19 encoding and surrogateespace error handler instead of the locale encoding to
20 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
21
Victor Stinner372ac5e2010-05-17 01:26:01 +000022- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace

35 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
36
Victor Stinner0964ee12010-04-30 16:48:45 +000037- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of

60 benefit compared to the dynamic memory allocation fallback. Patch by
61 Charles-François Natali.
62
Benjamin Peterson8380dd52010-04-16 22:51:37 +000063- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
64 passed to bytes or bytearray.

91
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000092- Issue #7845: Rich comparison methods on the complex type now return
93 NotImplemented rather than raising a TypeError when comparing with an
94 incompatible type; this allows user-defined classes to implement their own
95 comparisons with complex.
96
Victor Stinner52f6dd72010-03-12 14:45:56 +000097- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt

129
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000130- Issue #7385: Fix a crash in `MemoryView_FromObject` when
131 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.

139 suite_mask, and product_type.
140
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000141- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
142 could crash in many places because of the PyByteArray_AS_STRING() macro
143 returning NULL. The macro now returns a statically allocated empty
144 string instead.
145
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000146- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
147 where the right hand operand is a set of constants, by turning the set into
148 a frozenset and pre-building it as a constant. The comparison operation
149 is made against the constant instead of building a new set each time it is
150 executed (a similar optimization already existed which turned a list of
151 constants into a pre-built tuple). Patch and additional tests by Dave
152 Malcolm.
153
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000154- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

159 alpha 2, including: (1) a serious 'wrong output' bug that could
160 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
161 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000162 strings corresponding to subnormal values, (3) a memory leak for
163 some values large enough to cause overflow, and (4) a number of
164 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000165
Benjamin Petersonaea44282010-01-04 01:10:28 +0000166- The __complex__ method is now looked up on the class of instances to make it

177 described in C99 Annex F.
178
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000179- Issue #1811: improve accuracy and cross-platform consistency for
180 true division of integers: the result of a/b is now correctly
181 rounded for ints a and b (at least on IEEE 754 platforms), and in
182 particular does not depend on the internal representation of an int.
183
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000184- Issue #6834: replace the implementation for the 'python' and 'pythonw'
185 executables on OSX.
186
187 These executables now work properly with the arch(1) command:
188 ``arch -ppc python`` will start a universal binary version of python
189 in PPC mode (unlike previous releases).
190
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000191- Issue #7466: segmentation fault when the garbage collector is called

325 strings in an efficient manner.
326
Antoine Pitrou8689a102010-04-01 16:53:15 +0000327- Issue #8276: PyEval_CallObject() is now only available in macro form. The
328 function declaration, which was kept for backwards compatibility reasons,
329 is now removed (the macro was introduced in 1997!).
330
Mark Dickinson93f562c2010-01-30 10:30:15 +0000331- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
332 analogous to PyLong_AsLongAndOverflow.
333
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000334- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
335 has '\0' at the end.
336
Mark Dickinsonde604012010-01-01 19:27:32 +0000337- Issue #5080: The argument parsing functions PyArg_ParseTuple,
338 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
339 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
340 DeprecationWarning for float arguments passed with the 'L' format
341 code. This will become a TypeError in a future version of Python,
342 to match the behaviour of the other integer format codes.
343
Georg Brandl1e28a272009-12-28 08:41:01 +0000344- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
345
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000346- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
347 in PyArg_ParseTupleAndKeywords.
348
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000349- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)
Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000350 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
351
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000352- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
353 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
354 should used for accessing the d_type and d_name members of structures
355 using PyDescr_COMMON.
356
357- Issue #6405: Remove duplicate type declarations in descrobject.h.

365 object at a specified file, function, and line number.
366
367- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
368 ``const char *`` as the string is stored beyond the call.
369
Benjamin Peterson05159c42009-12-03 03:01:27 +0000370- Issue #2422: When compiled with the ``--with-valgrind`` option, the
371 pymalloc allocator will be automatically disabled when running under
372 Valgrind. This gives improved memory leak detection when running
373 under Valgrind, while taking advantage of pymalloc at other times.

419 objects.
420
Benjamin Peterson225168e2010-05-06 22:29:53 +0000421- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
422 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
423 file system encoding with the surrogateescape error handler (instead of
424 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

434 Patch by Tres Seaver.
435
Victor Stinnerde629d42010-05-05 21:43:57 +0000436- Issue #8390: tarfile uses surrogateespace as the default error handler

443
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000444- Issue #8567: Fix precedence of signals in Decimal module: when a
445 Decimal operation raises multiple signals and more than one of those
446 signals is trapped, the specification determines the order in which
447 the signals should be handled. In many cases this order wasn't
448 being followed, leading to the wrong Python exception being raised.
449
Antoine Pitrou6be88762010-05-03 16:48:20 +0000450- Issue #7865: The close() method of :mod:`io` objects should not swallow

480 and mappings.
481
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000482- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
483 where the method could block indefinitely if called just before the
484 event loop started running. This also fixes the occasional freezes
485 witnessed in test_httpservers.
486
Antoine Pitrou40f08742010-04-24 22:04:40 +0000487- Issue #8524: When creating an SSL socket, the timeout value of the
488 original socket wasn't retained (instead, a socket with a positive timeout
489 would be turned into a non-blocking SSL socket).
490
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000491- Issue #5103: SSL handshake would ignore the socket timeout and block
492 indefinitely if the other end didn't respond.
493
494- The do_handshake() method of SSL objects now adjusts the blocking mode of
495 the SSL structure if necessary (as other methods already do).
496
Victor Stinner13bb71c2010-04-23 21:41:56 +0000497- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

511 a non-infinite timeout. Also make that method friendlier with applications
512 wanting to continue using the socket in clear-text mode, by disabling
513 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
514
Antoine Pitrou7062db82010-04-22 13:30:10 +0000515- Issue #8496: make mailcap.lookup() always return a list, rather than an

578 character sets will now consistently use a Content-Transfer-Encoding of
579 7bit rather than sometimes being marked as 8bit.
580
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000581- Issue #8375: test_distutils now checks if the temporary directory are still

588 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
589 and `ssl.OPENSSL_VERSION_NUMBER`.
590
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000591- Add functools.total_ordering() and functools.cmp_to_key().
592
Mark Dickinson089b00c2010-04-03 15:51:03 +0000593- Issue #8257: The Decimal construct now accepts a float instance
594 directly, converting that float to a Decimal of equal value:
595
596 >>> Decimal(1.1)
597 Decimal('1.100000000000000088817841970012523233890533447265625')

600 instances directly.
601
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000602- Issue #7279: Comparisons involving a Decimal signaling NaN now
603 signal InvalidOperation instead of returning False. (Comparisons
604 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
605 are now hashable; Decimal signaling NaNs remain unhashable.
606
607- Issue #2531: Comparison operations between floats and Decimal
608 instances now return a result based on the numeric values of the
609 operands; previously they returned an arbitrary result based on
610 the relative ordering of id(float) and id(Decimal).
611

613
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000614- Issue #8233: When run as a script, py_compile.py optionally takes a single
615 argument `-` which tells it to read files to compile from stdin. Each line
616 is read on demand and the named file is compiled immediately. (Original
617 patch by Piotr Ożarowski).
618
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000619- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
620 form feed (0x0C) are now considered linebreaks, as specified in Unicode
621 Standard Annex #14. See issue #7643.
622 http://www.unicode.org/reports/tr14/
623
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000624- Comparisons using one of <, <=, >, >= between a complex instance and
625 a Fractions instance now raise TypeError instead of returning
626 True/False. This makes Fraction <=> complex comparisons consistent with
627 int <=> complex, float <=> complex, and complex <=> complex comparisons.
628

642
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000643- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.

669
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000670- The internals of the subprocess module on POSIX systems have been replaced
671 by an extension module (_posixsubprocess) so that the fork()+exec() can be
672 done safely without the possibility of deadlock in multithreaded applications.
673
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000674- subprocess.Popen now has restore_signals and start_new_session features.
675 The default of restore_signals=True is a new behavior compared to earlier
676 Python versions. This means that signals such as SIGPIPE are not ignored
677 by default in subprocesses launched by Python (Issue #1652).
678
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000679- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

739 exception of canonical and is_canonical) now accept instances of int
740 and long wherever a Decimal instance is accepted, and implicitly

765 file position when calling `truncate()`. It would previously change the
766 file position to the given argument, which goes against the tradition of
767 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
768
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000769- Issue #7610: Reworked implementation of the internal
770 :class:`zipfile.ZipExtFile` class used to represent files stored inside

773 It also solves an issue where interleaved calls to `read()` and
774 `readline()` give wrong results. Patch by Nir Aides.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000937- Issue #6816: runpy now provides a run_path function that allows Python code
938 to execute file paths that refer to source or compiled Python files as well
939 as zipfiles, directories and other valid sys.path entries that contain a

Victor Stinnere125f132010-05-15 21:04:43 +0000960 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +0000961 recursive locks as fast as regular non-recursive locks (previously,
962 they were slower by 10x to 15x).

982 reading from stdin so that existing input does not confuse it and
983 lead to incorrect entry or an IOError. It also properly flushes it

1248 gcc. (Optimization was unintentionally turned on in gcc

R. David Murrayba311052009-12-04 00:09:14 +00001407 file in the Lib/test directory, which might be read-only for the
1408 user running the tests.
1409
R. David Murray35768ad2009-11-15 00:23:21 +00001410- Issue #7324: add a sanity check to regrtest argument parsing to

1414 a test fails. Can be combined with -j.
1415
Antoine Pitrou060cee22009-11-13 16:29:04 +00001416- Issue #6551: test_zipimport could import and then destroy some modules of
1417 the encodings package, which would make other tests fail further down
1418 the road because the internally cached encoders and decoders would point
1419 to empty global variables.
1420
Antoine Pitrou941ee882009-11-11 20:59:38 +00001421- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1433
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001434- Issue #7222: Make thread "reaping" more reliable so that reference
1435 leak-chasing test runs give sensible results. The previous method of
1436 reaping threads could return successfully while some Thread objects were
1437 still referenced. This also introduces a new private function:
1438 :func:`_thread._count()`.
1439
R. David Murray27144602009-10-19 15:26:16 +00001440- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1441 longer runs the risk of causing the worker thread to fail.
1442
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001443- Issue #7055: test___all__ now greedily detects all modules which have an
1444 __all__ attribute, rather than using a hardcoded and incomplete list.
1445
R. David Murray0bc11ae2009-10-18 22:18:17 +00001446- Issue #7058: Added save/restore for things like sys.argv and cwd to

1448 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001449

1451
Brett Cannon3c273842009-07-20 00:14:29 +00001452- Fixed tests in importlib.test.source.test_abc_loader that were masking
1453 the proper exceptions that should be raised for missing or improper code
1454 object bytecode.
1455
Brett Cannonb49c70c2009-07-15 04:08:33 +00001456- Removed importlib's custom test discovery code and switched to
1457 unittest.TestLoader.discover().

1646 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001727- Issue #5914: Add new C API function PyOS_string_to_double, and
1728 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1729
Eric Smith741191f2009-05-06 13:08:15 +00001730- Issue #3382: float.__format__, complex.__format__, and %-formatting
1731 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1732 affects nan -> NAN and inf -> INF.
1733
Mark Hammond5a607a32009-05-06 08:04:54 +00001734- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1735 in all operations, including splitdrive, split, etc. splitunc() now issues
1736 a PendingDeprecation warning.
1737
Eric Smith63376222009-05-05 14:04:18 +00001738- Issue #5920: For float.__format__, change the behavior with the
1739 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1740 to be like 'g' but with at least one decimal point and with a
1741 default precision of 12. Previously, the behavior the same but with
1742 a default precision of 6. This more closely matches str(), and
1743 reduces surprises when adding alignment flags to the empty
1744 presentation type. This also affects the new complex.__format__ in
1745 the same way.
1746
Martin v. Löwis011e8422009-05-05 04:43:17 +00001747- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001758- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1759 received a new method, detach(). detach() disconnects the underlying stream
1760 from the buffer or text IO and returns it.
1761
Mark Dickinson33841c32009-05-01 15:37:04 +00001762- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1763 floats with absolute value over 1e50. Also remove length
1764 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1765 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001767- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001768 format(complex(1, 2./3), '.5') now produces a sensible result.
1769
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001770- Issue #5864: Fix empty format code formatting for floats so that it
1771 never gives more than the requested number of significant digits.
1772
Eric Smith6dc46f52009-04-27 20:39:49 +00001773- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1780
Benjamin Peterson193152c2009-04-25 01:08:45 +00001781- Issue #5283: Setting __class__ in __del__ caused a segfault.
1782
Mark Dickinsonad476da2009-04-23 19:14:16 +00001783- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1784 z involves nans, infs or negative zeros.
1785
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001786- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001787
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001788- Issue #1869 (and many duplicates): make round(x, n) correctly
1789 rounded for a float x, by using the decimal <-> binary conversions
1790 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1791 consistently agrees with format(x, '.2f').
1792
Benjamin Petersonae937c02009-04-18 20:54:08 +00001793- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1794 some builtin types.
1795
Eric Smith0923d1d2009-04-16 20:16:10 +00001796- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1797
Eric Smith35e84722009-04-16 20:21:28 +00001798- Issue #5515: str.format() type 'n' combined with commas and leading
1799 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001800
1801- Implement PEP 378, Format Specifier for Thousands Separator, for
1802 floats.
1803
Mark Dickinson3370cce2009-04-17 22:40:53 +00001804- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001805 1e11, not 1e12. This avoids printing 13 significant digits in
1806 situations where only 12 of them are correct. Example problem
1807 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1808 long time.)
1809
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001810- Issue #1580: On most platforms, use a 'short' float repr: for a
1811 finite float x, repr(x) now outputs a string based on the shortest
1812 sequence of decimal digits that rounds to x. Previous behaviour was
1813 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001814 Another minor difference is that the new repr switches to
1815 exponential notation at 1e16 instead of the previous 1e17; this
1816 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001817
1818 There's a new sys attribute sys.float_repr_style, which takes
1819 the value 'short' to indicate that we're using short float repr,
1820 and 'legacy' if the short float repr isn't available for one
1821 reason or another.
1822
1823 The float repr change involves incorporating David Gay's 'perfect
1824 rounding' code into the Python core (it's in Python/dtoa.c). As a
1825 secondary consequence, all string-to-float and float-to-string
1826 conversions (including all float formatting operations) will be
1827 correctly rounded on these platforms.
1828
1829 See issue 1580 discussions for details of platforms for which
1830 this change does not apply.
1831
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001832- Issue #5759: float() didn't call __float__ on str subclasses.
1833
Georg Brandlabc38772009-04-12 15:51:51 +00001834- The string.maketrans() function is deprecated; there is a new static method
1835 maketrans() on the bytes and bytearray classes. This removes confusion about
1836 the types string.maketrans() is supposed to work with, and mirrors the
1837 methods available on the str class.
1838
R. David Murraydc6da8a2009-04-09 22:16:43 +00001839- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00001845- Issue #3739: The unicode-internal encoder now reports the number of characters

2071 (typically /dev/zero under Unix) could crash the interpreter.
2072
Benjamin Peterson59406a92009-03-26 17:10:29 +00002073- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

2075
Lars Gustäbel42e00912009-03-22 20:34:29 +00002076- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2077 forever on incomplete input. That caused tarfile.open() to hang when used
2078 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2079 partial bzip2 compressed data.
2080
Mark Dickinson79f52032009-03-17 23:12:51 +00002081- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002100 struct.error instead of returning b'\xff\xff\xff\xff'. The
2101 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

2121 contained non ascii character on windows.
2122
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002123- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2124 source has already been decoded into str.
2125
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002126- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2127 rotating the object pointer by 4 bits to the right.
2128
Mark Dickinson87ec0852009-02-09 17:15:59 +00002129- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2130 it now forces its argument to double before testing for infinity.
2131
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002132- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2133 returns a non-number type.
2134
Benjamin Peterson87618552009-02-08 15:00:52 +00002135- Issue #5182: Removed memoryview.__str__.

2140 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002141
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002142- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002143 were suppressing all exceptions. These include list() and bytearray().
2144
Mark Dickinson1124e712009-01-28 21:25:58 +00002145- Issue #4707: round(x, n) now returns an integer if x is an integer.
2146 Previously it returned a float.
2147
Antoine Pitroub52ec782009-01-25 16:34:23 +00002148- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2149 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2150 evaluation loop is compiled with a new dispatch mechanism which gives
2151 speedups of up to 20%, depending on the system, on various benchmarks.
2152
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002153- Issue #4874: Most builtin decoders now reject unicode input.

2159
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002160- Issue #4838: When a module is deallocated, free the memory backing the
2161 optional module state data.
2162
Mark Dickinson8055afd2009-01-17 10:04:45 +00002163- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2164 type to (void *).
2165
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002166- Issue #4935: The overflow checking code in the expandtabs() method common
2167 to str, bytes and bytearray could be optimized away by the compiler, letting
2168 the interpreter segfault instead of raising an error.
2169
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002170- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2171 __next__ method.
2172
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002173- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2174 function no longer attempt to call the __long__ slot to convert an object
2175 to an integer. Only the __int__ and __trunc__ slots are examined.
2176
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002177- Issue #4893: Use NT threading on CE.
2178
Martin v. Löwisec59d042009-01-12 07:59:10 +00002179- Issue #4915: Port sysmodule to Windows CE.
2180
Antoine Pitrouab868312009-01-10 15:40:25 +00002181- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2182 common cases are optimized thanks to a dedicated fast path and a moderate
2183 amount of loop unrolling.
2184
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002185- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2186 collecting the oldest generation) so that allocating lots of objects without
2187 destroying them does not show quadratic performance. Based on a proposal by
2188 Martin von Löwis at
2189 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2190
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002191- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002192 having been closed (for instance, a read() call could return some
2193 previously buffered data). Patch by Dmitry Vasiliev.
2194
Antoine Pitrou05608432009-01-09 18:53:14 +00002195- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2196 flag to work properly. Furthermore, when specifying -u, the text stdout
2197 and stderr streams have line-by-line buffering enabled (the default being
2198 to buffer arbitrary chunks of data).
2199
Raymond Hettinger35631532009-01-09 03:58:09 +00002200- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2201 instead of ints (reducing its size from 4 to 8 times thereby reducing
2202 Python's overall memory).
2203
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002204- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2205 an existing .py counterpart, override the co_filename attributes of all
2206 code objects if the original filename is obsolete (which can happen if the
2207 file has been renamed, moved, or if it is accessed through different paths).
2208 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2209
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002210- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2211 one byte. Also fixes the meaning of len() so that it returns the number of
2212 items, rather than the size in bytes.
2213
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002214- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2215
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002216- Issue #4747: When the terminal does not use utf-8, executing a script with
2217 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2218
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002219- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002220 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002221
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002222- Issue #3680: Reference cycles created through a dict, set or deque iterator
2223 did not get collected.
2224
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002225- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2226 where the tp_hash and tp_dict slots are both NULL.
2227
Georg Brandlccc47b62008-12-28 11:44:14 +00002228- Issue #4759: None is now allowed as the first argument of
2229 bytearray.translate(). It was always allowed for bytes.translate().
2230
Skip Montanaro80072cb2008-12-23 03:51:14 +00002231- Added test case to ensure attempts to read from a file opened for writing
2232 fail.
2233
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002234- Issue #3106: Speedup some comparisons (str/str and int/int).

2238
Antoine Pitrou621601a2008-12-17 23:18:19 +00002239- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2240 print elapsed times, not only when some objects are uncollectable /
2241 unreachable. Original patch by Neil Schemenauer.
2242
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002243- Issue #3439: Add a bit_length method to int.
2244
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002245- Issue #2173: When getting device encoding, check that return value of
2246 nl_langinfo is not the empty string. This was causing silent build
2247 failures on OS X.
2248
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002249- Issue #4597: Fixed several opcodes that weren't always propagating
2250 exceptions.
2251
2252- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002253 context manager returns a value that cannot be converted to a bool.
2254
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002255- Issue #4445: Replace "sizeof(PyBytesObject)" with
2256 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2257 bytes instances. On a typical machine this saves 3 bytes of memory
2258 (on average) per allocation of a bytes instance.
2259
Christian Heimesa872de52008-12-05 08:26:55 +00002260- Issue #4533: File read operation was dreadfully slow due to a slowly
2261 growing read buffer. Fixed by using the same growth rate algorithm as
2262 Python 2.x.
2263
Antoine Pitrou5504e892008-12-06 21:27:53 +00002264- Issue #4509: Various issues surrounding resize of bytearray objects to
2265 which there are buffer exports (e.g. memoryview instances).
2266
Georg Brandlf9734072008-12-07 15:30:06 +00002267- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2268 method on file objects with closefd=False. The file descriptor is still
2269 kept open but the file object behaves like a closed file. The ``FileIO``
2270 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002271
Antoine Pitroubc420402008-12-07 20:14:49 +00002272- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2278
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002279- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2280 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2281 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2282 of using the replace error handler in PyUnicode_DecodeUTF8().
