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.

608 a test fails. Can be combined with -j.
609
Antoine Pitrou060cee22009-11-13 16:29:04 +0000610- Issue #6551: test_zipimport could import and then destroy some modules of
611 the encodings package, which would make other tests fail further down
612 the road because the internally cached encoders and decoders would point
613 to empty global variables.
614
Antoine Pitrou941ee882009-11-11 20:59:38 +0000615- Issue #7295: Do not use a hardcoded file name in test_tarfile.

618 primitives such as Lock, RLock, Condition, Event and Semaphore.
619
Brett Cannoncfed0292009-11-05 01:26:57 +0000620- Issue #7248 (part 2): Use a unique temporary directory for importlib source
621 tests instead of tempfile.tempdir. This prevents the tests from sharing state
622 between concurrent executions on the same system.
623
Brett Cannon0ae45112009-11-05 01:17:22 +0000624- Issue #7248: In importlib.test.source.util a try/finally block did not make
625 sure that some referenced objects actually were created in the block before
626 calling methods on the object.
627
Antoine Pitrou65c9c642009-10-30 17:25:12 +0000628- Issue #7222: Make thread "reaping" more reliable so that reference
629 leak-chasing test runs give sensible results. The previous method of
630 reaping threads could return successfully while some Thread objects were
631 still referenced. This also introduces a new private function:
632 :func:`_thread._count()`.
633
R. David Murray27144602009-10-19 15:26:16 +0000634- Issue #7151: fixed regrtest -j so that output to stderr from a test no
635 longer runs the risk of causing the worker thread to fail.
636
Antoine Pitrou4de39cd2009-10-10 21:08:31 +0000637- Issue #7055: test___all__ now greedily detects all modules which have an
638 __all__ attribute, rather than using a hardcoded and incomplete list.
639
R. David Murray0bc11ae2009-10-18 22:18:17 +0000640- Issue #7058: Added save/restore for things like sys.argv and cwd to
641 runtest_inner in regrtest, with warnings if the called test modifies them,
642 and a new section in the summary report at the end.

Mark Dickinson2e304402009-10-04 18:43:54 +0000644- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
645
Brett Cannon3c273842009-07-20 00:14:29 +0000646- Fixed tests in importlib.test.source.test_abc_loader that were masking
647 the proper exceptions that should be raised for missing or improper code
648 object bytecode.
649
Brett Cannonb49c70c2009-07-15 04:08:33 +0000650- Removed importlib's custom test discovery code and switched to

Mark Hammond5a607a32009-05-06 08:04:54 +0000921- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
922 in all operations, including splitdrive, split, etc. splitunc() now issues
923 a PendingDeprecation warning.
924
Eric Smith63376222009-05-05 14:04:18 +0000925- Issue #5920: For float.__format__, change the behavior with the
926 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
927 to be like 'g' but with at least one decimal point and with a
928 default precision of 12. Previously, the behavior the same but with
929 a default precision of 6. This more closely matches str(), and
930 reduces surprises when adding alignment flags to the empty
931 presentation type. This also affects the new complex.__format__ in
932 the same way.
933
Martin v. Löwis011e8422009-05-05 04:43:17 +0000934- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
935
R. David Murrayb18500d2009-05-04 22:59:07 +0000936- Issue #5890: in subclasses of 'property' the __doc__ attribute was
937 shadowed by classtype's, even if it was None. property now
938 inserts the __doc__ into the subclass instance __dict__.
939
Antoine Pitrou244651a2009-05-04 18:56:13 +0000940- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Martin v. Löwisdb12d452009-05-02 18:52:14 +0000944
Benjamin Petersond2e0c792009-05-01 20:40:59 +0000945- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
946 received a new method, detach(). detach() disconnects the underlying stream
947 from the buffer or text IO and returns it.
948
Mark Dickinson33841c32009-05-01 15:37:04 +0000949- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
950 floats with absolute value over 1e50. Also remove length
951 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
952 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +0000953
Eric Smith741191f2009-05-06 13:08:15 +0000954- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +0000955 format(complex(1, 2./3), '.5') now produces a sensible result.
956
Mark Dickinsond3ca5572009-04-29 18:47:07 +0000957- Issue #5864: Fix empty format code formatting for floats so that it
958 never gives more than the requested number of significant digits.
959
Eric Smith6dc46f52009-04-27 20:39:49 +0000960- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +0000970- Issue #5816: complex(repr(z)) now recovers z exactly, even when
971 z involves nans, infs or negative zeros.
972
Mark Dickinson4a16e3a2009-04-23 19:15:48 +0000973- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +0000974
Mark Dickinsone6a076d2009-04-18 11:48:33 +0000975- Issue #1869 (and many duplicates): make round(x, n) correctly
976 rounded for a float x, by using the decimal <-> binary conversions
977 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
978 consistently agrees with format(x, '.2f').
979
Benjamin Petersonae937c02009-04-18 20:54:08 +0000980- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
981 some builtin types.
982
Eric Smith0923d1d2009-04-16 20:16:10 +0000983- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
984
Eric Smith35e84722009-04-16 20:21:28 +0000985- Issue #5515: str.format() type 'n' combined with commas and leading
986 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +0000987
988- Implement PEP 378, Format Specifier for Thousands Separator, for
989 floats.
990
Mark Dickinson3370cce2009-04-17 22:40:53 +0000991- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000992 1e11, not 1e12. This avoids printing 13 significant digits in
993 situations where only 12 of them are correct. Example problem
994 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
995 long time.)
996
Mark Dickinsonb08a53a2009-04-16 19:52:09 +0000997- Issue #1580: On most platforms, use a 'short' float repr: for a
998 finite float x, repr(x) now outputs a string based on the shortest
999 sequence of decimal digits that rounds to x. Previous behaviour was
1000 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001001 Another minor difference is that the new repr switches to
1002 exponential notation at 1e16 instead of the previous 1e17; this
1003 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001004
1005 There's a new sys attribute sys.float_repr_style, which takes
1006 the value 'short' to indicate that we're using short float repr,
1007 and 'legacy' if the short float repr isn't available for one
1008 reason or another.
1009
1010 The float repr change involves incorporating David Gay's 'perfect
1011 rounding' code into the Python core (it's in Python/dtoa.c). As a
1012 secondary consequence, all string-to-float and float-to-string
1013 conversions (including all float formatting operations) will be
1014 correctly rounded on these platforms.
1015
1016 See issue 1580 discussions for details of platforms for which
1017 this change does not apply.
1018
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001019- Issue #5759: float() didn't call __float__ on str subclasses.
1020
Georg Brandlabc38772009-04-12 15:51:51 +00001021- The string.maketrans() function is deprecated; there is a new static method
1022 maketrans() on the bytes and bytearray classes. This removes confusion about
1023 the types string.maketrans() is supposed to work with, and mirrors the
1024 methods available on the str class.
1025
R. David Murraydc6da8a2009-04-09 22:16:43 +00001026- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1189
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001190- Issue #4688: Add a heuristic so that tuples and dicts containing only
1191 untrackable objects are not tracked by the garbage collector. This can
1192 reduce the size of collections and therefore the garbage collection overhead
1193 on long-running programs, depending on their particular use of datatypes.

1314 rotating the object pointer by 4 bits to the right.
1315
Mark Dickinson87ec0852009-02-09 17:15:59 +00001316- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1317 it now forces its argument to double before testing for infinity.
1318
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001319- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1327 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001328
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001329- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001330 were suppressing all exceptions. These include list() and bytearray().
1331
Mark Dickinson1124e712009-01-28 21:25:58 +00001332- Issue #4707: round(x, n) now returns an integer if x is an integer.
1333 Previously it returned a float.
1334
Antoine Pitroub52ec782009-01-25 16:34:23 +00001335- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1336 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1337 evaluation loop is compiled with a new dispatch mechanism which gives
1338 speedups of up to 20%, depending on the system, on various benchmarks.
1339
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001340- Issue #4874: Most builtin decoders now reject unicode input.

1346
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001347- Issue #4838: When a module is deallocated, free the memory backing the
1348 optional module state data.
1349
Mark Dickinson8055afd2009-01-17 10:04:45 +00001350- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1351 type to (void *).
1352
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001353- Issue #4935: The overflow checking code in the expandtabs() method common
1354 to str, bytes and bytearray could be optimized away by the compiler, letting
1355 the interpreter segfault instead of raising an error.
1356
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001357- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1358 __next__ method.
1359
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001360- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1361 function no longer attempt to call the __long__ slot to convert an object
1362 to an integer. Only the __int__ and __trunc__ slots are examined.
1363
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001364- Issue #4893: Use NT threading on CE.
1365
Martin v. Löwisec59d042009-01-12 07:59:10 +00001366- Issue #4915: Port sysmodule to Windows CE.
1367
Antoine Pitrouab868312009-01-10 15:40:25 +00001368- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1369 common cases are optimized thanks to a dedicated fast path and a moderate
1370 amount of loop unrolling.
1371
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001372- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1373 collecting the oldest generation) so that allocating lots of objects without
1374 destroying them does not show quadratic performance. Based on a proposal by
1375 Martin von Löwis at
1376 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1377
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001378- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001379 having been closed (for instance, a read() call could return some
1380 previously buffered data). Patch by Dmitry Vasiliev.
1381
Antoine Pitrou05608432009-01-09 18:53:14 +00001382- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1383 flag to work properly. Furthermore, when specifying -u, the text stdout
1384 and stderr streams have line-by-line buffering enabled (the default being
1385 to buffer arbitrary chunks of data).
1386
Raymond Hettinger35631532009-01-09 03:58:09 +00001387- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1388 instead of ints (reducing its size from 4 to 8 times thereby reducing
1389 Python's overall memory).
1390
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001391- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1392 an existing .py counterpart, override the co_filename attributes of all
1393 code objects if the original filename is obsolete (which can happen if the
1394 file has been renamed, moved, or if it is accessed through different paths).
1395 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1396
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001397- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1398 one byte. Also fixes the meaning of len() so that it returns the number of
1399 items, rather than the size in bytes.
1400
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001401- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1402
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001403- Issue #4747: When the terminal does not use utf-8, executing a script with
1404 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1405
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001406- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001407 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001408
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001409- Issue #3680: Reference cycles created through a dict, set or deque iterator
1410 did not get collected.
1411
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001412- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1413 where the tp_hash and tp_dict slots are both NULL.
1414
Georg Brandlccc47b62008-12-28 11:44:14 +00001415- Issue #4759: None is now allowed as the first argument of
1416 bytearray.translate(). It was always allowed for bytes.translate().
1417
Skip Montanaro80072cb2008-12-23 03:51:14 +00001418- Added test case to ensure attempts to read from a file opened for writing
1419 fail.
1420
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001421- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00001423- Issue #2183: Simplify and optimize bytecode for list, dict and set
1424 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1425
Antoine Pitrou621601a2008-12-17 23:18:19 +00001426- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1427 print elapsed times, not only when some objects are uncollectable /
1428 unreachable. Original patch by Neil Schemenauer.
1429
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001430- Issue #3439: Add a bit_length method to int.
1431
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001432- Issue #2173: When getting device encoding, check that return value of
1433 nl_langinfo is not the empty string. This was causing silent build
1434 failures on OS X.
1435
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001436- Issue #4597: Fixed several opcodes that weren't always propagating
1437 exceptions.
1438
1439- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001440 context manager returns a value that cannot be converted to a bool.
1441
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001442- Issue #4445: Replace "sizeof(PyBytesObject)" with
1443 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1444 bytes instances. On a typical machine this saves 3 bytes of memory
1445 (on average) per allocation of a bytes instance.
1446
Christian Heimesa872de52008-12-05 08:26:55 +00001447- Issue #4533: File read operation was dreadfully slow due to a slowly
1448 growing read buffer. Fixed by using the same growth rate algorithm as
1449 Python 2.x.
1450
Antoine Pitrou5504e892008-12-06 21:27:53 +00001451- Issue #4509: Various issues surrounding resize of bytearray objects to
1452 which there are buffer exports (e.g. memoryview instances).
1453
Georg Brandlf9734072008-12-07 15:30:06 +00001454- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1455 method on file objects with closefd=False. The file descriptor is still
1456 kept open but the file object behaves like a closed file. The ``FileIO``
1457 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001458
Antoine Pitroubc420402008-12-07 20:14:49 +00001459- Issue #4569: Interpreter crash when mutating a memoryview with an item size
1460 larger than 1.

1465
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001466- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1467 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1468 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1469 of using the replace error handler in PyUnicode_DecodeUTF8().
