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.

72 on 64-bit machines. The shift count for either left or right shift is
73 permitted to be up to sys.maxsize.
74
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000075- Ensure that tokenization of identifiers is not affected by locale.

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

128 deprecations.
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

323
Benjamin Petersonfb886362010-04-24 18:21:17 +0000324- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
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.

364- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
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.

Victor Stinner2ca03c12010-05-19 17:00:07 +0000378- Issue #8663: distutils.log emulates backslashreplace error handler. Fix
379 compilation in a non-ASCII directory if stdout encoding is ASCII (eg. if
380 stdout is not a TTY).
381
Victor Stinnerb745a742010-05-18 17:17:23 +0000382- Issue #8513: os.get_exec_path() supports b'PATH' key and bytes value.
383 subprocess.Popen() and os._execvpe() support bytes program name. Add
384 os.supports_bytes_environ flag: True if the native OS type of the environment
385 is bytes (eg. False on Windows).
386
Lars Gustäbel1465cc22010-05-17 18:02:50 +0000387- Issue #8633: tarfile is now able to read and write archives with "raw" binary

410 given.
411
Victor Stinner449c4662010-05-08 11:10:09 +0000412- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
413 for use in the file system, environment variables or the command line.
414
Antoine Pitrou89562712010-05-07 17:04:02 +0000415- Issue #8571: Fix an internal error when compressing or decompressing a

417 objects.
418
Benjamin Peterson225168e2010-05-06 22:29:53 +0000419- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
420 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
421 file system encoding with the surrogateescape error handler (instead of
422 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000423
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000424- Issue #8573: asyncore _strerror() function might throw ValueError.
425
Victor Stinnere125f132010-05-15 21:04:43 +0000426- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
427 error messages when accessing undefined class attributes because of the cheap
428 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000429 The cheap inheritance has been deprecated.
430

432 Patch by Tres Seaver.
433
Victor Stinnerde629d42010-05-05 21:43:57 +0000434- Issue #8390: tarfile uses surrogateespace as the default error handler
435 (instead of replace in read mode or strict in write mode)
436

441
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000442- Issue #8567: Fix precedence of signals in Decimal module: when a
443 Decimal operation raises multiple signals and more than one of those
444 signals is trapped, the specification determines the order in which
445 the signals should be handled. In many cases this order wasn't
446 being followed, leading to the wrong Python exception being raised.
447
Antoine Pitrou6be88762010-05-03 16:48:20 +0000448- Issue #7865: The close() method of :mod:`io` objects should not swallow

478 and mappings.
479
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000480- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
481 where the method could block indefinitely if called just before the
482 event loop started running. This also fixes the occasional freezes
483 witnessed in test_httpservers.
484
Antoine Pitrou40f08742010-04-24 22:04:40 +0000485- Issue #8524: When creating an SSL socket, the timeout value of the
486 original socket wasn't retained (instead, a socket with a positive timeout
487 would be turned into a non-blocking SSL socket).
488
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000489- Issue #5103: SSL handshake would ignore the socket timeout and block
490 indefinitely if the other end didn't respond.
491
492- The do_handshake() method of SSL objects now adjusts the blocking mode of
493 the SSL structure if necessary (as other methods already do).
494
Victor Stinner13bb71c2010-04-23 21:41:56 +0000495- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
496 and bytes strings for environment keys and values
497
Victor Stinner4d078042010-04-23 19:28:32 +0000498- Issue #8467: Pure Python implementation of subprocess encodes the error

Sean Reifscheider13daf122010-04-23 09:29:52 +0000504- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
505 the string "python" as the *ident*. openlog() arguments are all optional
506 and keywords.

509 a non-infinite timeout. Also make that method friendlier with applications
510 wanting to continue using the socket in clear-text mode, by disabling
511 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
512
Antoine Pitrou7062db82010-04-22 13:30:10 +0000513- Issue #8496: make mailcap.lookup() always return a list, rather than an

576 character sets will now consistently use a Content-Transfer-Encoding of
577 7bit rather than sometimes being marked as 8bit.
578
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000579- Issue #8375: test_distutils now checks if the temporary directory are still

586 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
587 and `ssl.OPENSSL_VERSION_NUMBER`.
588
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000589- Add functools.total_ordering() and functools.cmp_to_key().
590
Mark Dickinson089b00c2010-04-03 15:51:03 +0000591- Issue #8257: The Decimal construct now accepts a float instance
592 directly, converting that float to a Decimal of equal value:
593
594 >>> Decimal(1.1)
595 Decimal('1.100000000000000088817841970012523233890533447265625')

598 instances directly.
599
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000600- Issue #7279: Comparisons involving a Decimal signaling NaN now
601 signal InvalidOperation instead of returning False. (Comparisons
602 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
603 are now hashable; Decimal signaling NaNs remain unhashable.
604
605- Issue #2531: Comparison operations between floats and Decimal
606 instances now return a result based on the numeric values of the
607 operands; previously they returned an arbitrary result based on
608 the relative ordering of id(float) and id(Decimal).
609
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000610- Added a subtract() method to collections.Counter().

Barry Warsawd5f9bf52010-03-31 21:36:22 +0000612- Issue #8233: When run as a script, py_compile.py optionally takes a single
613 argument `-` which tells it to read files to compile from stdin. Each line
614 is read on demand and the named file is compiled immediately. (Original
615 patch by Piotr Ożarowski).
616
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000617- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
618 form feed (0x0C) are now considered linebreaks, as specified in Unicode
619 Standard Annex #14. See issue #7643.

621
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000622- Comparisons using one of <, <=, >, >= between a complex instance and
623 a Fractions instance now raise TypeError instead of returning
624 True/False. This makes Fraction <=> complex comparisons consistent with
625 int <=> complex, float <=> complex, and complex <=> complex comparisons.

640
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000641- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.

667
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000668- The internals of the subprocess module on POSIX systems have been replaced
669 by an extension module (_posixsubprocess) so that the fork()+exec() can be
670 done safely without the possibility of deadlock in multithreaded applications.
671
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000672- subprocess.Popen now has restore_signals and start_new_session features.
673 The default of restore_signals=True is a new behavior compared to earlier
674 Python versions. This means that signals such as SIGPIPE are not ignored
675 by default in subprocesses launched by Python (Issue #1652).
676
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000677- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

763 file position when calling `truncate()`. It would previously change the
764 file position to the given argument, which goes against the tradition of
765 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
766
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000767- Issue #7610: Reworked implementation of the internal
768 :class:`zipfile.ZipExtFile` class used to represent files stored inside
769 an archive. The new implementation is significantly faster and can

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

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000935- Issue #6816: runpy now provides a run_path function that allows Python code
936 to execute file paths that refer to source or compiled Python files as well
937 as zipfiles, directories and other valid sys.path entries that contain a

Victor Stinnere125f132010-05-15 21:04:43 +0000958 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +0000959 recursive locks as fast as regular non-recursive locks (previously,
960 they were slower by 10x to 15x).

980 reading from stdin so that existing input does not confuse it and

1246 gcc. (Optimization was unintentionally turned on in gcc

R. David Murrayba311052009-12-04 00:09:14 +00001405 file in the Lib/test directory, which might be read-only for the
1406 user running the tests.
1407
R. David Murray35768ad2009-11-15 00:23:21 +00001408- Issue #7324: add a sanity check to regrtest argument parsing to

1412 a test fails. Can be combined with -j.
1413
Antoine Pitrou060cee22009-11-13 16:29:04 +00001414- Issue #6551: test_zipimport could import and then destroy some modules of
1415 the encodings package, which would make other tests fail further down
1416 the road because the internally cached encoders and decoders would point
1417 to empty global variables.
1418
Antoine Pitrou941ee882009-11-11 20:59:38 +00001419- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1431
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001432- Issue #7222: Make thread "reaping" more reliable so that reference
1433 leak-chasing test runs give sensible results. The previous method of
1434 reaping threads could return successfully while some Thread objects were
1435 still referenced. This also introduces a new private function:
1436 :func:`_thread._count()`.
1437
R. David Murray27144602009-10-19 15:26:16 +00001438- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1439 longer runs the risk of causing the worker thread to fail.
1440
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001441- Issue #7055: test___all__ now greedily detects all modules which have an
1442 __all__ attribute, rather than using a hardcoded and incomplete list.
1443
R. David Murray0bc11ae2009-10-18 22:18:17 +00001444- Issue #7058: Added save/restore for things like sys.argv and cwd to

1446 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001447
Mark Dickinson2e304402009-10-04 18:43:54 +00001448- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1449
Brett Cannon3c273842009-07-20 00:14:29 +00001450- Fixed tests in importlib.test.source.test_abc_loader that were masking
1451 the proper exceptions that should be raised for missing or improper code
1452 object bytecode.
1453
Brett Cannonb49c70c2009-07-15 04:08:33 +00001454- Removed importlib's custom test discovery code and switched to
1455 unittest.TestLoader.discover().

1644 than an int, which makes some operations possible under 64-bit Linux (e.g.

1724
Mark Dickinson865e01a2009-05-07 16:37:01 +00001725- Issue #5914: Add new C API function PyOS_string_to_double, and
1726 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1727
Eric Smith741191f2009-05-06 13:08:15 +00001728- Issue #3382: float.__format__, complex.__format__, and %-formatting
1729 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1730 affects nan -> NAN and inf -> INF.
1731
Mark Hammond5a607a32009-05-06 08:04:54 +00001732- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1733 in all operations, including splitdrive, split, etc. splitunc() now issues
1734 a PendingDeprecation warning.
1735
Eric Smith63376222009-05-05 14:04:18 +00001736- Issue #5920: For float.__format__, change the behavior with the
1737 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1738 to be like 'g' but with at least one decimal point and with a
1739 default precision of 12. Previously, the behavior the same but with
1740 a default precision of 6. This more closely matches str(), and
1741 reduces surprises when adding alignment flags to the empty
1742 presentation type. This also affects the new complex.__format__ in
1743 the same way.
1744
Martin v. Löwis011e8422009-05-05 04:43:17 +00001745- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1753
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001754- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001756- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1757 received a new method, detach(). detach() disconnects the underlying stream
1758 from the buffer or text IO and returns it.
1759
Mark Dickinson33841c32009-05-01 15:37:04 +00001760- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1761 floats with absolute value over 1e50. Also remove length
1762 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1763 12.34 no longer raise an exception.

Eric Smith58a42242009-04-30 01:00:33 +00001766 format(complex(1, 2./3), '.5') now produces a sensible result.
1767
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001768- Issue #5864: Fix empty format code formatting for floats so that it
1769 never gives more than the requested number of significant digits.
1770
Eric Smith6dc46f52009-04-27 20:39:49 +00001771- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1778
Benjamin Peterson193152c2009-04-25 01:08:45 +00001779- Issue #5283: Setting __class__ in __del__ caused a segfault.
1780
Mark Dickinsonad476da2009-04-23 19:14:16 +00001781- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1782 z involves nans, infs or negative zeros.
1783
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001784- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001785
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001786- Issue #1869 (and many duplicates): make round(x, n) correctly
1787 rounded for a float x, by using the decimal <-> binary conversions
1788 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1789 consistently agrees with format(x, '.2f').
1790
Benjamin Petersonae937c02009-04-18 20:54:08 +00001791- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1792 some builtin types.
1793
Eric Smith0923d1d2009-04-16 20:16:10 +00001794- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1795
Eric Smith35e84722009-04-16 20:21:28 +00001796- Issue #5515: str.format() type 'n' combined with commas and leading
1797 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001798
1799- Implement PEP 378, Format Specifier for Thousands Separator, for
1800 floats.
1801
Mark Dickinson3370cce2009-04-17 22:40:53 +00001802- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001803 1e11, not 1e12. This avoids printing 13 significant digits in
1804 situations where only 12 of them are correct. Example problem
1805 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1806 long time.)
1807
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001808- Issue #1580: On most platforms, use a 'short' float repr: for a
1809 finite float x, repr(x) now outputs a string based on the shortest
1810 sequence of decimal digits that rounds to x. Previous behaviour was
1811 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001812 Another minor difference is that the new repr switches to
1813 exponential notation at 1e16 instead of the previous 1e17; this
1814 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001815
1816 There's a new sys attribute sys.float_repr_style, which takes
1817 the value 'short' to indicate that we're using short float repr,
1818 and 'legacy' if the short float repr isn't available for one
1819 reason or another.
1820
1821 The float repr change involves incorporating David Gay's 'perfect
1822 rounding' code into the Python core (it's in Python/dtoa.c). As a
1823 secondary consequence, all string-to-float and float-to-string
1824 conversions (including all float formatting operations) will be
1825 correctly rounded on these platforms.
1826
1827 See issue 1580 discussions for details of platforms for which
1828 this change does not apply.
1829
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001830- Issue #5759: float() didn't call __float__ on str subclasses.
1831
Georg Brandlabc38772009-04-12 15:51:51 +00001832- The string.maketrans() function is deprecated; there is a new static method
1833 maketrans() on the bytes and bytearray classes. This removes confusion about
1834 the types string.maketrans() is supposed to work with, and mirrors the
1835 methods available on the str class.
1836
R. David Murraydc6da8a2009-04-09 22:16:43 +00001837- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00001843- Issue #3739: The unicode-internal encoder now reports the number of characters

2073
Lars Gustäbel42e00912009-03-22 20:34:29 +00002074- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2075 forever on incomplete input. That caused tarfile.open() to hang when used
2076 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2077 partial bzip2 compressed data.
2078
Mark Dickinson79f52032009-03-17 23:12:51 +00002079- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002098 struct.error instead of returning b'\xff\xff\xff\xff'. The
2099 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

2119 contained non ascii character on windows.
2120
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002121- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2122 source has already been decoded into str.
2123
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002124- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2125 rotating the object pointer by 4 bits to the right.
2126
Mark Dickinson87ec0852009-02-09 17:15:59 +00002127- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2128 it now forces its argument to double before testing for infinity.
2129
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002130- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2131 returns a non-number type.
2132
Benjamin Peterson87618552009-02-08 15:00:52 +00002133- Issue #5182: Removed memoryview.__str__.

2138 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002139
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002140- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002141 were suppressing all exceptions. These include list() and bytearray().
2142
Mark Dickinson1124e712009-01-28 21:25:58 +00002143- Issue #4707: round(x, n) now returns an integer if x is an integer.
2144 Previously it returned a float.
2145
Antoine Pitroub52ec782009-01-25 16:34:23 +00002146- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2147 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2148 evaluation loop is compiled with a new dispatch mechanism which gives
2149 speedups of up to 20%, depending on the system, on various benchmarks.
2150
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002151- Issue #4874: Most builtin decoders now reject unicode input.

2157
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002158- Issue #4838: When a module is deallocated, free the memory backing the
2159 optional module state data.
2160
Mark Dickinson8055afd2009-01-17 10:04:45 +00002161- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2162 type to (void *).
2163
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002164- Issue #4935: The overflow checking code in the expandtabs() method common
2165 to str, bytes and bytearray could be optimized away by the compiler, letting
2166 the interpreter segfault instead of raising an error.
2167
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002168- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2169 __next__ method.
2170
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002171- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2172 function no longer attempt to call the __long__ slot to convert an object
2173 to an integer. Only the __int__ and __trunc__ slots are examined.
2174
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002175- Issue #4893: Use NT threading on CE.
2176
Martin v. Löwisec59d042009-01-12 07:59:10 +00002177- Issue #4915: Port sysmodule to Windows CE.
2178
Antoine Pitrouab868312009-01-10 15:40:25 +00002179- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2180 common cases are optimized thanks to a dedicated fast path and a moderate
2181 amount of loop unrolling.
2182
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002183- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2184 collecting the oldest generation) so that allocating lots of objects without
2185 destroying them does not show quadratic performance. Based on a proposal by
2186 Martin von Löwis at
2187 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2188
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002189- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002190 having been closed (for instance, a read() call could return some
2191 previously buffered data). Patch by Dmitry Vasiliev.
2192
Antoine Pitrou05608432009-01-09 18:53:14 +00002193- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2194 flag to work properly. Furthermore, when specifying -u, the text stdout
2195 and stderr streams have line-by-line buffering enabled (the default being
2196 to buffer arbitrary chunks of data).
2197
Raymond Hettinger35631532009-01-09 03:58:09 +00002198- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2199 instead of ints (reducing its size from 4 to 8 times thereby reducing
2200 Python's overall memory).
2201
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002202- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2203 an existing .py counterpart, override the co_filename attributes of all
2204 code objects if the original filename is obsolete (which can happen if the
2205 file has been renamed, moved, or if it is accessed through different paths).
2206 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2207
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002208- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2209 one byte. Also fixes the meaning of len() so that it returns the number of
2210 items, rather than the size in bytes.
2211
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002212- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2213
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002214- Issue #4747: When the terminal does not use utf-8, executing a script with
2215 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2216
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002217- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002218 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002219
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002220- Issue #3680: Reference cycles created through a dict, set or deque iterator
2221 did not get collected.
2222
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002223- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2224 where the tp_hash and tp_dict slots are both NULL.
2225
Georg Brandlccc47b62008-12-28 11:44:14 +00002226- Issue #4759: None is now allowed as the first argument of
2227 bytearray.translate(). It was always allowed for bytes.translate().
2228
Skip Montanaro80072cb2008-12-23 03:51:14 +00002229- Added test case to ensure attempts to read from a file opened for writing
2230 fail.
2231
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002232- Issue #3106: Speedup some comparisons (str/str and int/int).

2235 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2236
Antoine Pitrou621601a2008-12-17 23:18:19 +00002237- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2238 print elapsed times, not only when some objects are uncollectable /
2239 unreachable. Original patch by Neil Schemenauer.
2240
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002241- Issue #3439: Add a bit_length method to int.
2242
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002243- Issue #2173: When getting device encoding, check that return value of
2244 nl_langinfo is not the empty string. This was causing silent build
2245 failures on OS X.
2246
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002247- Issue #4597: Fixed several opcodes that weren't always propagating
2248 exceptions.
2249
2250- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002251 context manager returns a value that cannot be converted to a bool.
2252
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002253- Issue #4445: Replace "sizeof(PyBytesObject)" with
2254 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2255 bytes instances. On a typical machine this saves 3 bytes of memory
2256 (on average) per allocation of a bytes instance.
2257
Christian Heimesa872de52008-12-05 08:26:55 +00002258- Issue #4533: File read operation was dreadfully slow due to a slowly
2259 growing read buffer. Fixed by using the same growth rate algorithm as
2260 Python 2.x.
2261
Antoine Pitrou5504e892008-12-06 21:27:53 +00002262- Issue #4509: Various issues surrounding resize of bytearray objects to
2263 which there are buffer exports (e.g. memoryview instances).
2264
Georg Brandlf9734072008-12-07 15:30:06 +00002265- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2266 method on file objects with closefd=False. The file descriptor is still
2267 kept open but the file object behaves like a closed file. The ``FileIO``
2268 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002269
Antoine Pitroubc420402008-12-07 20:14:49 +00002270- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2271 larger than 1.

2276
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002277- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2278 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2279 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2280 of using the replace error handler in PyUnicode_DecodeUTF8().
