81
Mark Dickinsonbc099642010-01-29 17:27:24 +000082- Issue #7788: Fix an interpreter crash produced by deleting a list
83 slice with very large step value.
84
Eric Smithf7bb5782010-01-27 00:44:57 +000085- Issue #7766: Change sys.getwindowsversion() return value to a named
86 tuple and add the additional members returned in an OSVERSIONINFOEX
87 structure. The new members are service_pack_major, service_pack_minor,
88 suite_mask, and product_type.
89
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000090- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
91 could crash in many places because of the PyByteArray_AS_STRING() macro
92 returning NULL. The macro now returns a statically allocated empty
93 string instead.
94
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000095- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
96 where the right hand operand is a set of constants, by turning the set into
97 a frozenset and pre-building it as a constant. The comparison operation
98 is made against the constant instead of building a new set each time it is
99 executed (a similar optimization already existed which turned a list of
100 constants into a pre-built tuple). Patch and additional tests by Dave
101 Malcolm.
102
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000103- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
104 methods of bytes, bytearray and unicode objects by using a common
105 implementation based on stringlib's fast search. Patch by Florent Xicluna.

108 alpha 2, including: (1) a serious 'wrong output' bug that could
109 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
110 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000111 strings corresponding to subnormal values, (3) a memory leak for
112 some values large enough to cause overflow, and (4) a number of
113 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000114
Benjamin Petersonaea44282010-01-04 01:10:28 +0000115- The __complex__ method is now looked up on the class of instances to make it

125 negative zero) in ** operator. The behaviour now conforms to that
126 described in C99 Annex F.
127
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000128- Issue #1811: improve accuracy and cross-platform consistency for
129 true division of integers: the result of a/b is now correctly
130 rounded for ints a and b (at least on IEEE 754 platforms), and in
131 particular does not depend on the internal representation of an int.
132
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000133- Issue #6834: replace the implementation for the 'python' and 'pythonw'
134 executables on OSX.
135
136 These executables now work properly with the arch(1) command:
137 ``arch -ppc python`` will start a universal binary version of python
138 in PPC mode (unlike previous releases).
139
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000140- Issue #7466: segmentation fault when the garbage collector is called

155 implement the relevant rich comparison methods.
156
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000157- Issue #7298: fixes for range and reversed(range(...)). Iteration
158 over range(a, b, c) incorrectly gave an empty iterator when a, b and
159 c fit in C long but the length of the range did not. Also fix
160 several cases where reversed(range(a, b, c)) gave wrong results, and
161 fix a refleak for reversed(range(a, b, c)) with large arguments.

202 and include information from the Unihan.txt file.
203
Mark Dickinson2683ab02009-09-29 19:21:35 +0000204- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
205 of producing internally inconsistent Python longs.

275 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
276 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
277 DeprecationWarning for float arguments passed with the 'L' format
278 code. This will become a TypeError in a future version of Python,
279 to match the behaviour of the other integer format codes.

R. David Murrayd48739f2010-04-14 18:59:18 +0000315- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
316
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000317- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
318 module now takes an optional timeout argument in seconds. Timeout support
319 relies on the system threading library, so as to avoid a semi-busy wait
320 loop.
321
Victor Stinner485fb562010-04-13 11:07:24 +0000322- Issue #8383: pickle and pickletools use surrogatepass error handler when
323 encoding unicode as utf8 to support lone surrogates and stay compatible with
324 Python 2.x and 3.0
325
R. David Murrayb2416e52010-04-12 16:58:02 +0000326- Issue #7585: difflib context and unified diffs now place a tab between
327 filename and date, conforming to the 'standards' they were originally
328 designed to follow. This improves compatibility with patch tools.
329
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000330- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
331 character sets will now consistently use a Content-Transfer-Encoding of
332 7bit rather than sometimes being marked as 8bit.
333
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000334- Issue #8375: test_distutils now checks if the temporary directory are still
335 present before it cleans them.
336
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000337- Issue #8374: Update the internal alias table in the :mod:`locale` module
338 to cover recent locale changes and additions.
339
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000340- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
341 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
342 and `ssl.OPENSSL_VERSION_NUMBER`.
343
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000344- Add functools.total_ordering() and functools.cmp_to_key().
345
Mark Dickinson089b00c2010-04-03 15:51:03 +0000346- Issue #8257: The Decimal construct now accepts a float instance
347 directly, converting that float to a Decimal of equal value:
348
349 >>> Decimal(1.1)
350 Decimal('1.100000000000000088817841970012523233890533447265625')
351
Mark Dickinson98127c32010-04-03 11:18:52 +0000352- Issue #8294: The Fraction constructor now accepts Decimal and float
353 instances directly.
354
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000355- Issue #7279: Comparisons involving a Decimal signaling NaN now
356 signal InvalidOperation instead of returning False. (Comparisons
357 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
358 are now hashable; Decimal signaling NaNs remain unhashable.
359
360- Issue #2531: Comparison operations between floats and Decimal
361 instances now return a result based on the numeric values of the
362 operands; previously they returned an arbitrary result based on
363 the relative ordering of id(float) and id(Decimal).
364
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000365- Added a subtract() method to collections.Counter().
366
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000367- Issue #8233: When run as a script, py_compile.py optionally takes a single
368 argument `-` which tells it to read files to compile from stdin. Each line
369 is read on demand and the named file is compiled immediately. (Original
370 patch by Piotr Ożarowski).
371
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000372- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
373 form feed (0x0C) are now considered linebreaks, as specified in Unicode
374 Standard Annex #14. See issue #7643.
375 http://www.unicode.org/reports/tr14/
376
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000377- Comparisons using one of <, <=, >, >= between a complex instance and
378 a Fractions instance now raise TypeError instead of returning
379 True/False. This makes Fraction <=> complex comparisons consistent with
380 int <=> complex, float <=> complex, and complex <=> complex comparisons.
381
Antoine Pitrou39b35432010-03-23 00:25:54 +0000382- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
383 some methods (such as oss_mixer_device.fileno()) were not available.
384 Initial patch by Bertrand Janin.
385
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000386- Issue #8205: Remove the "Modules" directory from sys.path when Python is
387 running from the build directory (POSIX only).
388
Antoine Pitrou910bd512010-03-22 20:11:09 +0000389- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
390 didn't support chflags() (for example ZFS under FreeBSD). The error is
391 now silenced.
392
R. David Murrayca2edce2010-03-22 17:48:48 +0000393- Issue #7860: platform.uname now reports the correct 'machine' type
394 when Python is running in WOW64 mode on 64 bit Windows.
395
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000396- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
397 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
398 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000399
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000400- Issue #4282: Fix the main function of the profile module for a non-ASCII
401 script, open the file in binary mode and not in text mode with the default
402 (utf8) encoding.
403
Florent Xicluna54467e02010-03-21 12:29:50 +0000404- Issue #8179: Fix macpath.realpath() on a non-existing path.
405
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000406- Issue #8024: Update the Unicode database to 5.2.
407
Benjamin Peterson00888932010-03-18 22:37:38 +0000408- Issue #8168: py_compile now handles files with utf-8 BOMS.
409
Benjamin Peterson689a5582010-03-18 22:29:52 +0000410- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
411 detected.
412
Martin v. Löwis4b003072010-03-16 13:19:21 +0000413- Issue #6716/2: Backslash-replace error output in compilall.
414
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000415- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
416 with Tcl/Tk-8.5.
417
Matthias Klosec33b9022010-03-16 00:36:26 +0000418- Issue #8140: extend compileall to compile single files. Add -i option.
419
Matthias Klose82f60912010-03-15 13:46:04 +0000420- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
421 the locale.
422
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000423- The internals of the subprocess module on POSIX systems have been replaced
424 by an extension module (_posixsubprocess) so that the fork()+exec() can be
425 done safely without the possibility of deadlock in multithreaded applications.
426
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000427- subprocess.Popen now has restore_signals and start_new_session features.
428 The default of restore_signals=True is a new behavior compared to earlier
429 Python versions. This means that signals such as SIGPIPE are not ignored
430 by default in subprocesses launched by Python (Issue #1652).
431
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000432- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
433 cElementTree module is updated too.
434

442 the replacement were all bytes. Patch by Antoine Pitrou.
443
Gerhard Häringf9cee222010-03-05 15:20:03 +0000444- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
445 bugs and allows loading SQLite extensions from shared libraries.
446
Ezio Melottida227042010-03-14 11:51:00 +0000447- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public
448 Review Issue #29 (http://unicode.org/review/pr-29.html).
Victor Stinner7ed9c4c2010-03-04 12:14:57 +0000449
Victor Stinnercee3ae82010-03-04 00:29:24 +0000450- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
451 reset also the pointer to the current pointer context.

460
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000461- Issue #691291: codecs.open() should not convert end of lines on reading and
462 writing.
463
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000464- Issue #7869: logging: improved diagnostic for format-time errors.

481 Noted by Kan-Ru Chen.
482

492 exception of canonical and is_canonical) now accept instances of int
493 and long wherever a Decimal instance is accepted, and implicitly
494 convert that argument to Decimal. Previously only some arguments
495 were converted.
496
R. David Murray1f449142010-02-11 00:15:05 +0000497- Issue #7835: shelve should no longer produce mysterious warnings during
498 interpreter shutdown.
499
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000500- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
501 in XML processing instructions and comments. These raw characters are
502 allowed by the XML specification, and are necessary when outputting e.g.
503 PHP code in a processing instruction. Patch by Neil Muller.
504

515 type is specified. Patch by Brian Curtin.
516
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000517- Issue #6939: Fix file I/O objects in the `io` module to keep the original
518 file position when calling `truncate()`. It would previously change the
519 file position to the given argument, which goes against the tradition of
520 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
521
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000522- Issue #7610: Reworked implementation of the internal
523 :class:`zipfile.ZipExtFile` class used to represent files stored inside
524 an archive. The new implementation is significantly faster and can
525 be wrapped in a :class:`io.BufferedReader` object for more speedups.
526 It also solves an issue where interleaved calls to `read()` and
527 `readline()` give wrong results. Patch by Nir Aides.
528
Jesse Noller1f0b6582010-01-27 03:36:01 +0000529- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
530 allowing for a maximum number of tasks within the pool to be completed by
531 the worker before that worker is terminated, and a new one created to
532 replace it.
533
Benjamin Petersond6326642010-01-27 02:25:58 +0000534- Issue #7792: Registering non-classes to ABCs raised an obscure error.
535
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000536- Issue #7785: Don't accept bytes in FileIO.write().
Benjamin Peterson255058f2010-01-27 01:47:14 +0000537
Ezio Melotti38f00332010-01-25 12:39:47 +0000538- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
539

611 the same as passing no argument.
612
Lars Gustäbel365aff32009-12-13 11:42:29 +0000613- Issue #7357: tarfile no longer suppresses fatal extraction errors by

689
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000690- Issue #6816: runpy now provides a run_path function that allows Python code
691 to execute file paths that refer to source or compiled Python files as well
692 as zipfiles, directories and other valid sys.path entries that contain a
693 __main__.py file. This allows applications that run other Python scripts to
694 support the same flexibility as the CPython command line itself.
695
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000696- Issue #7318: multiprocessing now uses a timeout when it fails to establish
697 a connection with another process, rather than looping endlessly. The

713 default when instantiating a `threading.RLock` object. This makes
714 recursive locks as fast as regular non-recursive locks (previously,
715 they were slower by 10x to 15x).

731 a modification is done through it. This fixes inconsistencies and test
732 failures on systems with slightly bogus mtime behaviour.
733
Gregory P. Smith50467882009-11-01 18:42:17 +0000734- Issue #7246 & Issue #7208: getpass now properly flushes input before
735 reading from stdin so that existing input does not confuse it and
736 lead to incorrect entry or an IOError. It also properly flushes it
737 afterwards to avoid the terminal echoing the input afterwards on
738 OSes such as Solaris.

1123
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001124- Issue #7222: Make thread "reaping" more reliable so that reference
1125 leak-chasing test runs give sensible results. The previous method of
1126 reaping threads could return successfully while some Thread objects were
1127 still referenced. This also introduces a new private function:
1128 :func:`_thread._count()`.
1129
R. David Murray27144602009-10-19 15:26:16 +00001130- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1131 longer runs the risk of causing the worker thread to fail.
1132
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001133- Issue #7055: test___all__ now greedily detects all modules which have an

1138 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001139
Mark Dickinson2e304402009-10-04 18:43:54 +00001140- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1141
Brett Cannon3c273842009-07-20 00:14:29 +00001142- Fixed tests in importlib.test.source.test_abc_loader that were masking
1143 the proper exceptions that should be raised for missing or improper code
1144 object bytecode.
1145
Brett Cannonb49c70c2009-07-15 04:08:33 +00001146- Removed importlib's custom test discovery code and switched to

1334
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001335- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1336 than an int, which makes some operations possible under 64-bit Linux (e.g.
1337 DN_MULTISHOT with F_NOTIFY).

Mark Dickinson865e01a2009-05-07 16:37:01 +00001417- Issue #5914: Add new C API function PyOS_string_to_double, and
1418 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1419
Eric Smith741191f2009-05-06 13:08:15 +00001420- Issue #3382: float.__format__, complex.__format__, and %-formatting
1421 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1422 affects nan -> NAN and inf -> INF.
1423
Mark Hammond5a607a32009-05-06 08:04:54 +00001424- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1425 in all operations, including splitdrive, split, etc. splitunc() now issues
1426 a PendingDeprecation warning.
1427
Eric Smith63376222009-05-05 14:04:18 +00001428- Issue #5920: For float.__format__, change the behavior with the
1429 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1430 to be like 'g' but with at least one decimal point and with a
1431 default precision of 12. Previously, the behavior the same but with
1432 a default precision of 6. This more closely matches str(), and
1433 reduces surprises when adding alignment flags to the empty
1434 presentation type. This also affects the new complex.__format__ in
1435 the same way.
1436
Martin v. Löwis011e8422009-05-05 04:43:17 +00001437- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1445
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001446- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001448- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1449 received a new method, detach(). detach() disconnects the underlying stream
1450 from the buffer or text IO and returns it.
1451
Mark Dickinson33841c32009-05-01 15:37:04 +00001452- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1453 floats with absolute value over 1e50. Also remove length
1454 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinsond3ca5572009-04-29 18:47:07 +00001460- Issue #5864: Fix empty format code formatting for floats so that it
1461 never gives more than the requested number of significant digits.
1462
Eric Smith6dc46f52009-04-27 20:39:49 +00001463- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001478- Issue #1869 (and many duplicates): make round(x, n) correctly
1479 rounded for a float x, by using the decimal <-> binary conversions
1480 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1481 consistently agrees with format(x, '.2f').
1482
Benjamin Petersonae937c02009-04-18 20:54:08 +00001483- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith35e84722009-04-16 20:21:28 +00001488- Issue #5515: str.format() type 'n' combined with commas and leading
1489 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001490
1491- Implement PEP 378, Format Specifier for Thousands Separator, for
1492 floats.
1493
Mark Dickinson3370cce2009-04-17 22:40:53 +00001494- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001495 1e11, not 1e12. This avoids printing 13 significant digits in
1496 situations where only 12 of them are correct. Example problem
1497 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1498 long time.)
1499
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001500- Issue #1580: On most platforms, use a 'short' float repr: for a
1501 finite float x, repr(x) now outputs a string based on the shortest
1502 sequence of decimal digits that rounds to x. Previous behaviour was
1503 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001504 Another minor difference is that the new repr switches to
1505 exponential notation at 1e16 instead of the previous 1e17; this
1506 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001507
1508 There's a new sys attribute sys.float_repr_style, which takes
1509 the value 'short' to indicate that we're using short float repr,
1510 and 'legacy' if the short float repr isn't available for one
1511 reason or another.
1512
1513 The float repr change involves incorporating David Gay's 'perfect
1514 rounding' code into the Python core (it's in Python/dtoa.c). As a
1515 secondary consequence, all string-to-float and float-to-string
1516 conversions (including all float formatting operations) will be
1517 correctly rounded on these platforms.
1518
1519 See issue 1580 discussions for details of platforms for which
1520 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001522- Issue #5759: float() didn't call __float__ on str subclasses.
1523
Georg Brandlabc38772009-04-12 15:51:51 +00001524- The string.maketrans() function is deprecated; there is a new static method
1525 maketrans() on the bytes and bytearray classes. This removes confusion about
1526 the types string.maketrans() is supposed to work with, and mirrors the
1527 methods available on the str class.

1817 rotating the object pointer by 4 bits to the right.
1818
Mark Dickinson87ec0852009-02-09 17:15:59 +00001819- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001831
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001832- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001833 were suppressing all exceptions. These include list() and bytearray().

1839 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1840 evaluation loop is compiled with a new dispatch mechanism which gives
1841 speedups of up to 20%, depending on the system, on various benchmarks.
1842
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001843- Issue #4874: Most builtin decoders now reject unicode input.

1849
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001850- Issue #4838: When a module is deallocated, free the memory backing the
1851 optional module state data.
1852
Mark Dickinson8055afd2009-01-17 10:04:45 +00001853- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1854 type to (void *).
1855
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001856- Issue #4935: The overflow checking code in the expandtabs() method common
1857 to str, bytes and bytearray could be optimized away by the compiler, letting
1858 the interpreter segfault instead of raising an error.
1859
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001860- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1861 __next__ method.
1862
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001863- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1864 function no longer attempt to call the __long__ slot to convert an object
1865 to an integer. Only the __int__ and __trunc__ slots are examined.
1866
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001867- Issue #4893: Use NT threading on CE.
1868

1870
Antoine Pitrouab868312009-01-10 15:40:25 +00001871- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1872 common cases are optimized thanks to a dedicated fast path and a moderate
1873 amount of loop unrolling.
1874
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001875- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1876 collecting the oldest generation) so that allocating lots of objects without
1877 destroying them does not show quadratic performance. Based on a proposal by
1878 Martin von Löwis at
1879 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1880
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001881- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001882 having been closed (for instance, a read() call could return some
1883 previously buffered data). Patch by Dmitry Vasiliev.
1884
Antoine Pitrou05608432009-01-09 18:53:14 +00001885- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1886 flag to work properly. Furthermore, when specifying -u, the text stdout
1887 and stderr streams have line-by-line buffering enabled (the default being
1888 to buffer arbitrary chunks of data).
1889
Raymond Hettinger35631532009-01-09 03:58:09 +00001890- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1891 instead of ints (reducing its size from 4 to 8 times thereby reducing
1892 Python's overall memory).
1893
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001894- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1895 an existing .py counterpart, override the co_filename attributes of all
1896 code objects if the original filename is obsolete (which can happen if the
1897 file has been renamed, moved, or if it is accessed through different paths).
1898 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1899
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001900- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1901 one byte. Also fixes the meaning of len() so that it returns the number of
1902 items, rather than the size in bytes.
1903
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001904- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1905
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001906- Issue #4747: When the terminal does not use utf-8, executing a script with
1907 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1908
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001909- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001910 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001911
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001912- Issue #3680: Reference cycles created through a dict, set or deque iterator
1913 did not get collected.
1914
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001915- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1916 where the tp_hash and tp_dict slots are both NULL.
1917
Georg Brandlccc47b62008-12-28 11:44:14 +00001918- Issue #4759: None is now allowed as the first argument of
1919 bytearray.translate(). It was always allowed for bytes.translate().
1920
Skip Montanaro80072cb2008-12-23 03:51:14 +00001921- Added test case to ensure attempts to read from a file opened for writing
1922 fail.

1928
Antoine Pitrou621601a2008-12-17 23:18:19 +00001929- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1930 print elapsed times, not only when some objects are uncollectable /
1931 unreachable. Original patch by Neil Schemenauer.
1932
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001933- Issue #3439: Add a bit_length method to int.
1934
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001935- Issue #2173: When getting device encoding, check that return value of
1936 nl_langinfo is not the empty string. This was causing silent build
1937 failures on OS X.
1938
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001939- Issue #4597: Fixed several opcodes that weren't always propagating
1940 exceptions.
1941
1942- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001943 context manager returns a value that cannot be converted to a bool.
1944
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001945- Issue #4445: Replace "sizeof(PyBytesObject)" with
1946 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1947 bytes instances. On a typical machine this saves 3 bytes of memory
1948 (on average) per allocation of a bytes instance.
1949
Christian Heimesa872de52008-12-05 08:26:55 +00001950- Issue #4533: File read operation was dreadfully slow due to a slowly
1951 growing read buffer. Fixed by using the same growth rate algorithm as
1952 Python 2.x.
1953
Antoine Pitrou5504e892008-12-06 21:27:53 +00001954- Issue #4509: Various issues surrounding resize of bytearray objects to

1956
Georg Brandlf9734072008-12-07 15:30:06 +00001957- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1958 method on file objects with closefd=False. The file descriptor is still
1959 kept open but the file object behaves like a closed file. The ``FileIO``
1960 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001961
Antoine Pitroubc420402008-12-07 20:14:49 +00001962- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1968
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001969- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1970 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1971 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1972 of using the replace error handler in PyUnicode_DecodeUTF8().
