27
Mark Dickinsoncbb62742009-12-27 15:09:50 +000028- Issue #1811: improve accuracy and cross-platform consistency for
29 true division of integers: the result of a/b is now correctly
30 rounded for ints a and b (at least on IEEE 754 platforms), and in
31 particular does not depend on the internal representation of an int.
32
Ronald Oussoren6f6c5622009-12-24 14:03:19 +000033- Issue #6834: replace the implementation for the 'python' and 'pythonw'
34 executables on OSX.

58 over range(a, b, c) incorrectly gave an empty iterator when a, b and
59 c fit in C long but the length of the range did not. Also fix

Benjamin Peterson05159c42009-12-03 03:01:27 +0000189- Issue #2422: When compiled with the ``--with-valgrind`` option, the
190 pymalloc allocator will be automatically disabled when running under
191 Valgrind. This gives improved memory leak detection when running
192 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou060cee22009-11-13 16:29:04 +0000606- Issue #6551: test_zipimport could import and then destroy some modules of
607 the encodings package, which would make other tests fail further down
608 the road because the internally cached encoders and decoders would point
609 to empty global variables.
610
Antoine Pitrou941ee882009-11-11 20:59:38 +0000611- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrou557934f2009-11-06 22:41:14 +0000613- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
614 primitives such as Lock, RLock, Condition, Event and Semaphore.
615
Brett Cannoncfed0292009-11-05 01:26:57 +0000616- Issue #7248 (part 2): Use a unique temporary directory for importlib source
617 tests instead of tempfile.tempdir. This prevents the tests from sharing state
618 between concurrent executions on the same system.
619
Brett Cannon0ae45112009-11-05 01:17:22 +0000620- Issue #7248: In importlib.test.source.util a try/finally block did not make
621 sure that some referenced objects actually were created in the block before
622 calling methods on the object.
623
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000624- Issue #7222: Make thread "reaping" more reliable so that reference
625 leak-chasing test runs give sensible results. The previous method of
626 reaping threads could return successfully while some Thread objects were
627 still referenced. This also introduces a new private function:
628 :func:`_thread._count()`.
629
R. David Murray27144602009-10-19 15:26:16 +0000630- Issue #7151: fixed regrtest -j so that output to stderr from a test no
631 longer runs the risk of causing the worker thread to fail.
632
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000633- Issue #7055: test___all__ now greedily detects all modules which have an
634 __all__ attribute, rather than using a hardcoded and incomplete list.
635
R. David Murray0bc11ae2009-10-18 22:18:17 +0000636- Issue #7058: Added save/restore for things like sys.argv and cwd to
637 runtest_inner in regrtest, with warnings if the called test modifies them,
638 and a new section in the summary report at the end.

641
Brett Cannon3c273842009-07-20 00:14:29 +0000642- Fixed tests in importlib.test.source.test_abc_loader that were masking
643 the proper exceptions that should be raised for missing or improper code
644 object bytecode.
645
Brett Cannonb49c70c2009-07-15 04:08:33 +0000646- Removed importlib's custom test discovery code and switched to

918 in all operations, including splitdrive, split, etc. splitunc() now issues
919 a PendingDeprecation warning.
920
Eric Smith63376222009-05-05 14:04:18 +0000921- Issue #5920: For float.__format__, change the behavior with the
922 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
923 to be like 'g' but with at least one decimal point and with a
924 default precision of 12. Previously, the behavior the same but with
925 a default precision of 6. This more closely matches str(), and
926 reduces surprises when adding alignment flags to the empty
927 presentation type. This also affects the new complex.__format__ in
928 the same way.
929
Martin v. Löwis011e8422009-05-05 04:43:17 +0000930- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
931
R. David Murrayb18500d2009-05-04 22:59:07 +0000932- Issue #5890: in subclasses of 'property' the __doc__ attribute was
933 shadowed by classtype's, even if it was None. property now
934 inserts the __doc__ into the subclass instance __dict__.
935

Benjamin Petersond2e0c792009-05-01 20:40:59 +0000941- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
942 received a new method, detach(). detach() disconnects the underlying stream
943 from the buffer or text IO and returns it.
944
Mark Dickinson33841c32009-05-01 15:37:04 +0000945- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
946 floats with absolute value over 1e50. Also remove length
947 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
948 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000949
Eric Smith741191f2009-05-06 13:08:15 +0000950- Issue #1588: Add complex.__format__. For example,

952
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000953- Issue #5864: Fix empty format code formatting for floats so that it
954 never gives more than the requested number of significant digits.
955
Eric Smith6dc46f52009-04-27 20:39:49 +0000956- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +0000966- Issue #5816: complex(repr(z)) now recovers z exactly, even when
967 z involves nans, infs or negative zeros.

Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000969- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000970
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000971- Issue #1869 (and many duplicates): make round(x, n) correctly
972 rounded for a float x, by using the decimal <-> binary conversions
973 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
974 consistently agrees with format(x, '.2f').
975
Benjamin Petersonae937c02009-04-18 20:54:08 +0000976- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
977 some builtin types.
978
Eric Smith0923d1d2009-04-16 20:16:10 +0000979- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
980
Eric Smith35e84722009-04-16 20:21:28 +0000981- Issue #5515: str.format() type 'n' combined with commas and leading
982 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000983
984- Implement PEP 378, Format Specifier for Thousands Separator, for
985 floats.
986
Mark Dickinson3370cce2009-04-17 22:40:53 +0000987- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000988 1e11, not 1e12. This avoids printing 13 significant digits in
989 situations where only 12 of them are correct. Example problem
990 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
991 long time.)
992
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000993- Issue #1580: On most platforms, use a 'short' float repr: for a
994 finite float x, repr(x) now outputs a string based on the shortest
995 sequence of decimal digits that rounds to x. Previous behaviour was
996 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +0000997 Another minor difference is that the new repr switches to
998 exponential notation at 1e16 instead of the previous 1e17; this
999 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001000
1001 There's a new sys attribute sys.float_repr_style, which takes
1002 the value 'short' to indicate that we're using short float repr,
1003 and 'legacy' if the short float repr isn't available for one
1004 reason or another.
1005
1006 The float repr change involves incorporating David Gay's 'perfect
1007 rounding' code into the Python core (it's in Python/dtoa.c). As a
1008 secondary consequence, all string-to-float and float-to-string
1009 conversions (including all float formatting operations) will be
1010 correctly rounded on these platforms.
1011
1012 See issue 1580 discussions for details of platforms for which
1013 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001015- Issue #5759: float() didn't call __float__ on str subclasses.
1016
Georg Brandlabc38772009-04-12 15:51:51 +00001017- The string.maketrans() function is deprecated; there is a new static method
1018 maketrans() on the bytes and bytearray classes. This removes confusion about
1019 the types string.maketrans() is supposed to work with, and mirrors the
1020 methods available on the str class.

1185
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001186- Issue #4688: Add a heuristic so that tuples and dicts containing only
1187 untrackable objects are not tracked by the garbage collector. This can
1188 reduce the size of collections and therefore the garbage collection overhead
1189 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001283 struct.error instead of returning b'\xff\xff\xff\xff'. The
1284 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1285 have been removed from the struct module.

1310 rotating the object pointer by 4 bits to the right.
1311
Mark Dickinson87ec0852009-02-09 17:15:59 +00001312- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1313 it now forces its argument to double before testing for infinity.
1314
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001315- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1323 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001324
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001325- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001326 were suppressing all exceptions. These include list() and bytearray().
1327
Mark Dickinson1124e712009-01-28 21:25:58 +00001328- Issue #4707: round(x, n) now returns an integer if x is an integer.
1329 Previously it returned a float.
1330
Antoine Pitroub52ec782009-01-25 16:34:23 +00001331- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1332 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1333 evaluation loop is compiled with a new dispatch mechanism which gives
1334 speedups of up to 20%, depending on the system, on various benchmarks.
1335
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001336- Issue #4874: Most builtin decoders now reject unicode input.

1342
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001343- Issue #4838: When a module is deallocated, free the memory backing the
1344 optional module state data.
1345
Mark Dickinson8055afd2009-01-17 10:04:45 +00001346- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1347 type to (void *).
1348
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001349- Issue #4935: The overflow checking code in the expandtabs() method common
1350 to str, bytes and bytearray could be optimized away by the compiler, letting
1351 the interpreter segfault instead of raising an error.
1352
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001353- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1354 __next__ method.
1355
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001356- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1357 function no longer attempt to call the __long__ slot to convert an object
1358 to an integer. Only the __int__ and __trunc__ slots are examined.
1359
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001360- Issue #4893: Use NT threading on CE.
1361
Martin v. Löwisec59d042009-01-12 07:59:10 +00001362- Issue #4915: Port sysmodule to Windows CE.
1363
Antoine Pitrouab868312009-01-10 15:40:25 +00001364- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1365 common cases are optimized thanks to a dedicated fast path and a moderate
1366 amount of loop unrolling.
1367
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001368- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1369 collecting the oldest generation) so that allocating lots of objects without
1370 destroying them does not show quadratic performance. Based on a proposal by
1371 Martin von Löwis at
1372 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1373
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001374- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001375 having been closed (for instance, a read() call could return some
1376 previously buffered data). Patch by Dmitry Vasiliev.
1377
Antoine Pitrou05608432009-01-09 18:53:14 +00001378- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1379 flag to work properly. Furthermore, when specifying -u, the text stdout
1380 and stderr streams have line-by-line buffering enabled (the default being
1381 to buffer arbitrary chunks of data).
1382
Raymond Hettinger35631532009-01-09 03:58:09 +00001383- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1384 instead of ints (reducing its size from 4 to 8 times thereby reducing
1385 Python's overall memory).
1386
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001387- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1388 an existing .py counterpart, override the co_filename attributes of all
1389 code objects if the original filename is obsolete (which can happen if the
1390 file has been renamed, moved, or if it is accessed through different paths).
1391 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1392
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001393- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1394 one byte. Also fixes the meaning of len() so that it returns the number of
1395 items, rather than the size in bytes.
1396
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001397- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1398
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001399- Issue #4747: When the terminal does not use utf-8, executing a script with
1400 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1401
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001402- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001403 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001404
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001405- Issue #3680: Reference cycles created through a dict, set or deque iterator
1406 did not get collected.
1407
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001408- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1409 where the tp_hash and tp_dict slots are both NULL.
1410
Georg Brandlccc47b62008-12-28 11:44:14 +00001411- Issue #4759: None is now allowed as the first argument of
1412 bytearray.translate(). It was always allowed for bytes.translate().
1413
Skip Montanaro80072cb2008-12-23 03:51:14 +00001414- Added test case to ensure attempts to read from a file opened for writing
1415 fail.
1416
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001417- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001419- Issue #2183: Simplify and optimize bytecode for list, dict and set
1420 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1421
Antoine Pitrou621601a2008-12-17 23:18:19 +00001422- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1423 print elapsed times, not only when some objects are uncollectable /
1424 unreachable. Original patch by Neil Schemenauer.
1425
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001426- Issue #3439: Add a bit_length method to int.
1427
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001428- Issue #2173: When getting device encoding, check that return value of
1429 nl_langinfo is not the empty string. This was causing silent build
1430 failures on OS X.
1431
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001432- Issue #4597: Fixed several opcodes that weren't always propagating
1433 exceptions.
1434
1435- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001436 context manager returns a value that cannot be converted to a bool.
1437
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001438- Issue #4445: Replace "sizeof(PyBytesObject)" with
1439 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1440 bytes instances. On a typical machine this saves 3 bytes of memory
1441 (on average) per allocation of a bytes instance.
1442
Christian Heimesa872de52008-12-05 08:26:55 +00001443- Issue #4533: File read operation was dreadfully slow due to a slowly
1444 growing read buffer. Fixed by using the same growth rate algorithm as
1445 Python 2.x.
1446
Antoine Pitrou5504e892008-12-06 21:27:53 +00001447- Issue #4509: Various issues surrounding resize of bytearray objects to
1448 which there are buffer exports (e.g. memoryview instances).
1449
Georg Brandlf9734072008-12-07 15:30:06 +00001450- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1451 method on file objects with closefd=False. The file descriptor is still
1452 kept open but the file object behaves like a closed file. The ``FileIO``
1453 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001454
Antoine Pitroubc420402008-12-07 20:14:49 +00001455- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1456 larger than 1.

1461
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001462- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1463 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1464 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1465 of using the replace error handler in PyUnicode_DecodeUTF8().
