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.

200 The tables for code points representing numeric values, white spaces or line
201 breaks are now generated from the official Unicode Character Database files,
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.

Senthil Kumaranad02d232010-04-16 03:02:13 +0000315- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
316 Locke and Hans Ulrich Niedermann.
317
R. David Murrayd48739f2010-04-14 18:59:18 +0000318- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
319
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000320- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
321 module now takes an optional timeout argument in seconds. Timeout support
322 relies on the system threading library, so as to avoid a semi-busy wait
323 loop.
324
Victor Stinner485fb562010-04-13 11:07:24 +0000325- Issue #8383: pickle and pickletools use surrogatepass error handler when
326 encoding unicode as utf8 to support lone surrogates and stay compatible with
327 Python 2.x and 3.0
328
R. David Murrayb2416e52010-04-12 16:58:02 +0000329- Issue #7585: difflib context and unified diffs now place a tab between
330 filename and date, conforming to the 'standards' they were originally
331 designed to follow. This improves compatibility with patch tools.
332
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000333- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
334 character sets will now consistently use a Content-Transfer-Encoding of
335 7bit rather than sometimes being marked as 8bit.
336
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000337- Issue #8375: test_distutils now checks if the temporary directory are still
338 present before it cleans them.
339
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000340- Issue #8374: Update the internal alias table in the :mod:`locale` module
341 to cover recent locale changes and additions.
342
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000343- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
344 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
345 and `ssl.OPENSSL_VERSION_NUMBER`.
346
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000347- Add functools.total_ordering() and functools.cmp_to_key().
348
Mark Dickinson089b00c2010-04-03 15:51:03 +0000349- Issue #8257: The Decimal construct now accepts a float instance
350 directly, converting that float to a Decimal of equal value:
351
352 >>> Decimal(1.1)
353 Decimal('1.100000000000000088817841970012523233890533447265625')
354
Mark Dickinson98127c32010-04-03 11:18:52 +0000355- Issue #8294: The Fraction constructor now accepts Decimal and float
356 instances directly.
357
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000358- Issue #7279: Comparisons involving a Decimal signaling NaN now
359 signal InvalidOperation instead of returning False. (Comparisons
360 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
361 are now hashable; Decimal signaling NaNs remain unhashable.
362
363- Issue #2531: Comparison operations between floats and Decimal
364 instances now return a result based on the numeric values of the
365 operands; previously they returned an arbitrary result based on
366 the relative ordering of id(float) and id(Decimal).
367
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000368- Added a subtract() method to collections.Counter().
369
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000370- Issue #8233: When run as a script, py_compile.py optionally takes a single
371 argument `-` which tells it to read files to compile from stdin. Each line
372 is read on demand and the named file is compiled immediately. (Original
373 patch by Piotr Ożarowski).
374
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000375- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
376 form feed (0x0C) are now considered linebreaks, as specified in Unicode
377 Standard Annex #14. See issue #7643.
378 http://www.unicode.org/reports/tr14/
379
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000380- Comparisons using one of <, <=, >, >= between a complex instance and
381 a Fractions instance now raise TypeError instead of returning
382 True/False. This makes Fraction <=> complex comparisons consistent with
383 int <=> complex, float <=> complex, and complex <=> complex comparisons.
384
Antoine Pitrou39b35432010-03-23 00:25:54 +0000385- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
386 some methods (such as oss_mixer_device.fileno()) were not available.
387 Initial patch by Bertrand Janin.
388
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000389- Issue #8205: Remove the "Modules" directory from sys.path when Python is
390 running from the build directory (POSIX only).
391
Antoine Pitrou910bd512010-03-22 20:11:09 +0000392- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
393 didn't support chflags() (for example ZFS under FreeBSD). The error is
394 now silenced.
395
R. David Murrayca2edce2010-03-22 17:48:48 +0000396- Issue #7860: platform.uname now reports the correct 'machine' type
397 when Python is running in WOW64 mode on 64 bit Windows.
398
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000399- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
400 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
401 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000402
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000403- Issue #4282: Fix the main function of the profile module for a non-ASCII
404 script, open the file in binary mode and not in text mode with the default
405 (utf8) encoding.
406
Florent Xicluna54467e02010-03-21 12:29:50 +0000407- Issue #8179: Fix macpath.realpath() on a non-existing path.
408
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000409- Issue #8024: Update the Unicode database to 5.2.
410
Benjamin Peterson00888932010-03-18 22:37:38 +0000411- Issue #8168: py_compile now handles files with utf-8 BOMS.
412
Benjamin Peterson689a5582010-03-18 22:29:52 +0000413- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
414 detected.
415
Martin v. Löwis4b003072010-03-16 13:19:21 +0000416- Issue #6716/2: Backslash-replace error output in compilall.
417
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000418- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
419 with Tcl/Tk-8.5.
420
Matthias Klosec33b9022010-03-16 00:36:26 +0000421- Issue #8140: extend compileall to compile single files. Add -i option.
422
Matthias Klose82f60912010-03-15 13:46:04 +0000423- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
424 the locale.
425
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000426- The internals of the subprocess module on POSIX systems have been replaced
427 by an extension module (_posixsubprocess) so that the fork()+exec() can be
428 done safely without the possibility of deadlock in multithreaded applications.
429
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000430- subprocess.Popen now has restore_signals and start_new_session features.
431 The default of restore_signals=True is a new behavior compared to earlier
432 Python versions. This means that signals such as SIGPIPE are not ignored
433 by default in subprocesses launched by Python (Issue #1652).
434
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000435- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
436 cElementTree module is updated too.
437

445 the replacement were all bytes. Patch by Antoine Pitrou.
446
Gerhard Häringf9cee222010-03-05 15:20:03 +0000447- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
448 bugs and allows loading SQLite extensions from shared libraries.
449
Ezio Melottida227042010-03-14 11:51:00 +0000450- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public
451 Review Issue #29 (http://unicode.org/review/pr-29.html).
Victor Stinner7ed9c4c2010-03-04 12:14:57 +0000452
Victor Stinnercee3ae82010-03-04 00:29:24 +0000453- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
454 reset also the pointer to the current pointer context.

463
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000464- Issue #691291: codecs.open() should not convert end of lines on reading and
465 writing.
466
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000467- Issue #7869: logging: improved diagnostic for format-time errors.

481 to be ignored only to the first file. Noted by Bogdan Opanchuk.
482
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000483- Issue #7597: curses.use_env() can now be called before initscr().
484 Noted by Kan-Ru Chen.
485

495 exception of canonical and is_canonical) now accept instances of int
496 and long wherever a Decimal instance is accepted, and implicitly
497 convert that argument to Decimal. Previously only some arguments
498 were converted.
499
R. David Murray1f449142010-02-11 00:15:05 +0000500- Issue #7835: shelve should no longer produce mysterious warnings during
501 interpreter shutdown.
502
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000503- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
504 in XML processing instructions and comments. These raw characters are
505 allowed by the XML specification, and are necessary when outputting e.g.
506 PHP code in a processing instruction. Patch by Neil Muller.

518 type is specified. Patch by Brian Curtin.
519
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000520- Issue #6939: Fix file I/O objects in the `io` module to keep the original
521 file position when calling `truncate()`. It would previously change the
522 file position to the given argument, which goes against the tradition of
523 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
524
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000525- Issue #7610: Reworked implementation of the internal
526 :class:`zipfile.ZipExtFile` class used to represent files stored inside
527 an archive. The new implementation is significantly faster and can
528 be wrapped in a :class:`io.BufferedReader` object for more speedups.
529 It also solves an issue where interleaved calls to `read()` and
530 `readline()` give wrong results. Patch by Nir Aides.
531
Jesse Noller1f0b6582010-01-27 03:36:01 +0000532- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
533 allowing for a maximum number of tasks within the pool to be completed by
534 the worker before that worker is terminated, and a new one created to
535 replace it.
536
Benjamin Petersond6326642010-01-27 02:25:58 +0000537- Issue #7792: Registering non-classes to ABCs raised an obscure error.
538
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000539- Issue #7785: Don't accept bytes in FileIO.write().
Benjamin Peterson255058f2010-01-27 01:47:14 +0000540
Ezio Melotti38f00332010-01-25 12:39:47 +0000541- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
542

614 the same as passing no argument.
615
Lars Gustäbel365aff32009-12-13 11:42:29 +0000616- Issue #7357: tarfile no longer suppresses fatal extraction errors by

692
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000693- Issue #6816: runpy now provides a run_path function that allows Python code
694 to execute file paths that refer to source or compiled Python files as well
695 as zipfiles, directories and other valid sys.path entries that contain a
696 __main__.py file. This allows applications that run other Python scripts to
697 support the same flexibility as the CPython command line itself.
698
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000699- Issue #7318: multiprocessing now uses a timeout when it fails to establish

716 default when instantiating a `threading.RLock` object. This makes
717 recursive locks as fast as regular non-recursive locks (previously,
718 they were slower by 10x to 15x).
719

734 a modification is done through it. This fixes inconsistencies and test
735 failures on systems with slightly bogus mtime behaviour.
736
Gregory P. Smith50467882009-11-01 18:42:17 +0000737- Issue #7246 & Issue #7208: getpass now properly flushes input before
738 reading from stdin so that existing input does not confuse it and
739 lead to incorrect entry or an IOError. It also properly flushes it
740 afterwards to avoid the terminal echoing the input afterwards on
741 OSes such as Solaris.

1126
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001127- Issue #7222: Make thread "reaping" more reliable so that reference
1128 leak-chasing test runs give sensible results. The previous method of
1129 reaping threads could return successfully while some Thread objects were
1130 still referenced. This also introduces a new private function:
1131 :func:`_thread._count()`.
1132
R. David Murray27144602009-10-19 15:26:16 +00001133- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1134 longer runs the risk of causing the worker thread to fail.
1135
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001136- Issue #7055: test___all__ now greedily detects all modules which have an

1141 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001142
Mark Dickinson2e304402009-10-04 18:43:54 +00001143- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1144
Brett Cannon3c273842009-07-20 00:14:29 +00001145- Fixed tests in importlib.test.source.test_abc_loader that were masking
1146 the proper exceptions that should be raised for missing or improper code
1147 object bytecode.
1148
Brett Cannonb49c70c2009-07-15 04:08:33 +00001149- Removed importlib's custom test discovery code and switched to

1337
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001338- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1339 than an int, which makes some operations possible under 64-bit Linux (e.g.
1340 DN_MULTISHOT with F_NOTIFY).

Mark Dickinson865e01a2009-05-07 16:37:01 +00001420- Issue #5914: Add new C API function PyOS_string_to_double, and
1421 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1422
Eric Smith741191f2009-05-06 13:08:15 +00001423- Issue #3382: float.__format__, complex.__format__, and %-formatting
1424 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1425 affects nan -> NAN and inf -> INF.

Mark Hammond5a607a32009-05-06 08:04:54 +00001427- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1428 in all operations, including splitdrive, split, etc. splitunc() now issues
1429 a PendingDeprecation warning.

Eric Smith63376222009-05-05 14:04:18 +00001431- Issue #5920: For float.__format__, change the behavior with the
1432 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1433 to be like 'g' but with at least one decimal point and with a
1434 default precision of 12. Previously, the behavior the same but with
1435 a default precision of 6. This more closely matches str(), and
1436 reduces surprises when adding alignment flags to the empty
1437 presentation type. This also affects the new complex.__format__ in
1438 the same way.
1439
Martin v. Löwis011e8422009-05-05 04:43:17 +00001440- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1448
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001449- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001451- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1452 received a new method, detach(). detach() disconnects the underlying stream
1453 from the buffer or text IO and returns it.
1454
Mark Dickinson33841c32009-05-01 15:37:04 +00001455- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1456 floats with absolute value over 1e50. Also remove length
1457 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

1464 never gives more than the requested number of significant digits.
1465
Eric Smith6dc46f52009-04-27 20:39:49 +00001466- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001481- Issue #1869 (and many duplicates): make round(x, n) correctly
1482 rounded for a float x, by using the decimal <-> binary conversions
1483 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1484 consistently agrees with format(x, '.2f').

Eric Smith35e84722009-04-16 20:21:28 +00001491- Issue #5515: str.format() type 'n' combined with commas and leading
1492 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001493
1494- Implement PEP 378, Format Specifier for Thousands Separator, for
1495 floats.
1496
Mark Dickinson3370cce2009-04-17 22:40:53 +00001497- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001498 1e11, not 1e12. This avoids printing 13 significant digits in
1499 situations where only 12 of them are correct. Example problem
1500 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1501 long time.)
1502
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001503- Issue #1580: On most platforms, use a 'short' float repr: for a
1504 finite float x, repr(x) now outputs a string based on the shortest
1505 sequence of decimal digits that rounds to x. Previous behaviour was
1506 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001507 Another minor difference is that the new repr switches to
1508 exponential notation at 1e16 instead of the previous 1e17; this
1509 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001510
1511 There's a new sys attribute sys.float_repr_style, which takes
1512 the value 'short' to indicate that we're using short float repr,
1513 and 'legacy' if the short float repr isn't available for one
1514 reason or another.
1515
1516 The float repr change involves incorporating David Gay's 'perfect
1517 rounding' code into the Python core (it's in Python/dtoa.c). As a
1518 secondary consequence, all string-to-float and float-to-string
1519 conversions (including all float formatting operations) will be
1520 correctly rounded on these platforms.
1521
1522 See issue 1580 discussions for details of platforms for which
1523 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001525- Issue #5759: float() didn't call __float__ on str subclasses.
1526
Georg Brandlabc38772009-04-12 15:51:51 +00001527- The string.maketrans() function is deprecated; there is a new static method
1528 maketrans() on the bytes and bytearray classes. This removes confusion about
1529 the types string.maketrans() is supposed to work with, and mirrors the
1530 methods available on the str class.
1531
R. David Murraydc6da8a2009-04-09 22:16:43 +00001532- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00001538- Issue #3739: The unicode-internal encoder now reports the number of characters

1820 rotating the object pointer by 4 bits to the right.
1821
Mark Dickinson87ec0852009-02-09 17:15:59 +00001822- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001834
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001835- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001836 were suppressing all exceptions. These include list() and bytearray().

1842 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1843 evaluation loop is compiled with a new dispatch mechanism which gives
1844 speedups of up to 20%, depending on the system, on various benchmarks.
1845

1852
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001853- Issue #4838: When a module is deallocated, free the memory backing the
1854 optional module state data.
1855
Mark Dickinson8055afd2009-01-17 10:04:45 +00001856- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1857 type to (void *).
1858
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001859- Issue #4935: The overflow checking code in the expandtabs() method common
1860 to str, bytes and bytearray could be optimized away by the compiler, letting
1861 the interpreter segfault instead of raising an error.
1862
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001863- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1864 __next__ method.
1865
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001866- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1867 function no longer attempt to call the __long__ slot to convert an object
1868 to an integer. Only the __int__ and __trunc__ slots are examined.
1869
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001870- Issue #4893: Use NT threading on CE.
1871

1873
Antoine Pitrouab868312009-01-10 15:40:25 +00001874- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1875 common cases are optimized thanks to a dedicated fast path and a moderate
1876 amount of loop unrolling.
1877
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001878- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1879 collecting the oldest generation) so that allocating lots of objects without
1880 destroying them does not show quadratic performance. Based on a proposal by
1881 Martin von Löwis at
1882 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1883
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001884- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001885 having been closed (for instance, a read() call could return some
1886 previously buffered data). Patch by Dmitry Vasiliev.
1887
Antoine Pitrou05608432009-01-09 18:53:14 +00001888- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1889 flag to work properly. Furthermore, when specifying -u, the text stdout
1890 and stderr streams have line-by-line buffering enabled (the default being
1891 to buffer arbitrary chunks of data).
1892
Raymond Hettinger35631532009-01-09 03:58:09 +00001893- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1894 instead of ints (reducing its size from 4 to 8 times thereby reducing
1895 Python's overall memory).
1896
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001897- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1898 an existing .py counterpart, override the co_filename attributes of all
1899 code objects if the original filename is obsolete (which can happen if the
1900 file has been renamed, moved, or if it is accessed through different paths).
1901 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1902
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001903- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1904 one byte. Also fixes the meaning of len() so that it returns the number of
1905 items, rather than the size in bytes.
1906
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001907- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1908
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001909- Issue #4747: When the terminal does not use utf-8, executing a script with
1910 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1911
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001912- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001913 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001914
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001915- Issue #3680: Reference cycles created through a dict, set or deque iterator
1916 did not get collected.
1917
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001918- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1919 where the tp_hash and tp_dict slots are both NULL.
1920
Georg Brandlccc47b62008-12-28 11:44:14 +00001921- Issue #4759: None is now allowed as the first argument of
1922 bytearray.translate(). It was always allowed for bytes.translate().
1923
Skip Montanaro80072cb2008-12-23 03:51:14 +00001924- Added test case to ensure attempts to read from a file opened for writing
1925 fail.
1926
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001927- Issue #3106: Speedup some comparisons (str/str and int/int).

1931
Antoine Pitrou621601a2008-12-17 23:18:19 +00001932- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1933 print elapsed times, not only when some objects are uncollectable /
1934 unreachable. Original patch by Neil Schemenauer.
1935
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001936- Issue #3439: Add a bit_length method to int.
1937
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001938- Issue #2173: When getting device encoding, check that return value of
1939 nl_langinfo is not the empty string. This was causing silent build
1940 failures on OS X.
1941
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001942- Issue #4597: Fixed several opcodes that weren't always propagating
1943 exceptions.
1944
1945- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001946 context manager returns a value that cannot be converted to a bool.
1947
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001948- Issue #4445: Replace "sizeof(PyBytesObject)" with
1949 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1950 bytes instances. On a typical machine this saves 3 bytes of memory
1951 (on average) per allocation of a bytes instance.
1952
Christian Heimesa872de52008-12-05 08:26:55 +00001953- Issue #4533: File read operation was dreadfully slow due to a slowly
1954 growing read buffer. Fixed by using the same growth rate algorithm as
1955 Python 2.x.
1956
Antoine Pitrou5504e892008-12-06 21:27:53 +00001957- Issue #4509: Various issues surrounding resize of bytearray objects to
1958 which there are buffer exports (e.g. memoryview instances).
1959
Georg Brandlf9734072008-12-07 15:30:06 +00001960- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1961 method on file objects with closefd=False. The file descriptor is still
1962 kept open but the file object behaves like a closed file. The ``FileIO``
1963 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001964
Antoine Pitroubc420402008-12-07 20:14:49 +00001965- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1971
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001972- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1973 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1974 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1975 of using the replace error handler in PyUnicode_DecodeUTF8().
