84
Mark Dickinsonbc099642010-01-29 17:27:24 +000085- Issue #7788: Fix an interpreter crash produced by deleting a list
86 slice with very large step value.
87
Eric Smithf7bb5782010-01-27 00:44:57 +000088- Issue #7766: Change sys.getwindowsversion() return value to a named
89 tuple and add the additional members returned in an OSVERSIONINFOEX
90 structure. The new members are service_pack_major, service_pack_minor,
91 suite_mask, and product_type.
92
Antoine Pitroufc8d6f42010-01-17 12:38:54 +000093- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
94 could crash in many places because of the PyByteArray_AS_STRING() macro
95 returning NULL. The macro now returns a statically allocated empty
96 string instead.
97
Antoine Pitroub7fbcd32010-01-16 18:37:38 +000098- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
99 where the right hand operand is a set of constants, by turning the set into
100 a frozenset and pre-building it as a constant. The comparison operation
101 is made against the constant instead of building a new set each time it is
102 executed (a similar optimization already existed which turned a list of
103 constants into a pre-built tuple). Patch and additional tests by Dave
104 Malcolm.
105
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000106- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

111 alpha 2, including: (1) a serious 'wrong output' bug that could
112 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
113 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000114 strings corresponding to subnormal values, (3) a memory leak for
115 some values large enough to cause overflow, and (4) a number of
116 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000117
Benjamin Petersonaea44282010-01-04 01:10:28 +0000118- The __complex__ method is now looked up on the class of instances to make it

128 negative zero) in ** operator. The behaviour now conforms to that
129 described in C99 Annex F.
130
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000131- Issue #1811: improve accuracy and cross-platform consistency for
132 true division of integers: the result of a/b is now correctly
133 rounded for ints a and b (at least on IEEE 754 platforms), and in
134 particular does not depend on the internal representation of an int.
135
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000136- Issue #6834: replace the implementation for the 'python' and 'pythonw'
137 executables on OSX.
138
139 These executables now work properly with the arch(1) command:
140 ``arch -ppc python`` will start a universal binary version of python
141 in PPC mode (unlike previous releases).
142
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000143- Issue #7466: segmentation fault when the garbage collector is called

159
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000160- Issue #7298: fixes for range and reversed(range(...)). Iteration
161 over range(a, b, c) incorrectly gave an empty iterator when a, b and
162 c fit in C long but the length of the range did not. Also fix

Benjamin Peterson05159c42009-12-03 03:01:27 +0000313- Issue #2422: When compiled with the ``--with-valgrind`` option, the
314 pymalloc allocator will be automatically disabled when running under
315 Valgrind. This gives improved memory leak detection when running
316 under Valgrind, while taking advantage of pymalloc at other times.

325
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000326- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
327 code as stated in RFC-959 at chapter 5.4.
328
Victor Stinner738446f02010-04-18 00:00:44 +0000329- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
330 surrogates.
331
Antoine Pitrou0454af92010-04-17 23:51:58 +0000332- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000333 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

337
Victor Stinner0e59cc32010-04-16 23:49:32 +0000338- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
339 the current working directory.

351
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000352- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
353 module now takes an optional timeout argument in seconds. Timeout support
354 relies on the system threading library, so as to avoid a semi-busy wait
355 loop.
356
Victor Stinner485fb562010-04-13 11:07:24 +0000357- Issue #8383: pickle and pickletools use surrogatepass error handler when
358 encoding unicode as utf8 to support lone surrogates and stay compatible with
359 Python 2.x and 3.0
360
R. David Murrayb2416e52010-04-12 16:58:02 +0000361- Issue #7585: difflib context and unified diffs now place a tab between
362 filename and date, conforming to the 'standards' they were originally
363 designed to follow. This improves compatibility with patch tools.
364
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000365- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
366 character sets will now consistently use a Content-Transfer-Encoding of
367 7bit rather than sometimes being marked as 8bit.
368
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000369- Issue #8375: test_distutils now checks if the temporary directory are still

376 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
377 and `ssl.OPENSSL_VERSION_NUMBER`.
378
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000379- Add functools.total_ordering() and functools.cmp_to_key().
380
Mark Dickinson089b00c2010-04-03 15:51:03 +0000381- Issue #8257: The Decimal construct now accepts a float instance
382 directly, converting that float to a Decimal of equal value:
383
384 >>> Decimal(1.1)
385 Decimal('1.100000000000000088817841970012523233890533447265625')
386
Mark Dickinson98127c32010-04-03 11:18:52 +0000387- Issue #8294: The Fraction constructor now accepts Decimal and float
388 instances directly.
389
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000390- Issue #7279: Comparisons involving a Decimal signaling NaN now
391 signal InvalidOperation instead of returning False. (Comparisons
392 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
393 are now hashable; Decimal signaling NaNs remain unhashable.
394
395- Issue #2531: Comparison operations between floats and Decimal
396 instances now return a result based on the numeric values of the
397 operands; previously they returned an arbitrary result based on
398 the relative ordering of id(float) and id(Decimal).
399
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000400- Added a subtract() method to collections.Counter().
401
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000402- Issue #8233: When run as a script, py_compile.py optionally takes a single
403 argument `-` which tells it to read files to compile from stdin. Each line
404 is read on demand and the named file is compiled immediately. (Original
405 patch by Piotr Ożarowski).
406
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000407- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
408 form feed (0x0C) are now considered linebreaks, as specified in Unicode
409 Standard Annex #14. See issue #7643.
410 http://www.unicode.org/reports/tr14/
411
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000412- Comparisons using one of <, <=, >, >= between a complex instance and
413 a Fractions instance now raise TypeError instead of returning
414 True/False. This makes Fraction <=> complex comparisons consistent with
415 int <=> complex, float <=> complex, and complex <=> complex comparisons.
416
Antoine Pitrou39b35432010-03-23 00:25:54 +0000417- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
418 some methods (such as oss_mixer_device.fileno()) were not available.
419 Initial patch by Bertrand Janin.
420
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000421- Issue #8205: Remove the "Modules" directory from sys.path when Python is
422 running from the build directory (POSIX only).
423
Antoine Pitrou910bd512010-03-22 20:11:09 +0000424- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
425 didn't support chflags() (for example ZFS under FreeBSD). The error is
426 now silenced.
427
R. David Murrayca2edce2010-03-22 17:48:48 +0000428- Issue #7860: platform.uname now reports the correct 'machine' type
429 when Python is running in WOW64 mode on 64 bit Windows.
430
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000431- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
432 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
433 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000434
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000435- Issue #4282: Fix the main function of the profile module for a non-ASCII
436 script, open the file in binary mode and not in text mode with the default
437 (utf8) encoding.
438
Florent Xicluna54467e02010-03-21 12:29:50 +0000439- Issue #8179: Fix macpath.realpath() on a non-existing path.

444
Benjamin Peterson689a5582010-03-18 22:29:52 +0000445- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
446 detected.
447
Martin v. Löwis4b003072010-03-16 13:19:21 +0000448- Issue #6716/2: Backslash-replace error output in compilall.
449
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000450- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
451 with Tcl/Tk-8.5.
452
Matthias Klosec33b9022010-03-16 00:36:26 +0000453- Issue #8140: extend compileall to compile single files. Add -i option.

456 the locale.
457
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000458- The internals of the subprocess module on POSIX systems have been replaced
459 by an extension module (_posixsubprocess) so that the fork()+exec() can be
460 done safely without the possibility of deadlock in multithreaded applications.
461
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000462- subprocess.Popen now has restore_signals and start_new_session features.
463 The default of restore_signals=True is a new behavior compared to earlier
464 Python versions. This means that signals such as SIGPIPE are not ignored
465 by default in subprocesses launched by Python (Issue #1652).
466
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000467- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
468 cElementTree module is updated too.

477 the replacement were all bytes. Patch by Antoine Pitrou.
478
Gerhard Häringf9cee222010-03-05 15:20:03 +0000479- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
480 bugs and allows loading SQLite extensions from shared libraries.

513 to be ignored only to the first file. Noted by Bogdan Opanchuk.
514
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000515- Issue #7597: curses.use_env() can now be called before initscr().
516 Noted by Kan-Ru Chen.
517

524 bytecode file when it was less then 8 bytes.
525
Mark Dickinson84230a12010-02-18 14:49:50 +0000526- Issue #7633: In the decimal module, Context class methods (with the
527 exception of canonical and is_canonical) now accept instances of int
528 and long wherever a Decimal instance is accepted, and implicitly
529 convert that argument to Decimal. Previously only some arguments
530 were converted.
531
R. David Murray1f449142010-02-11 00:15:05 +0000532- Issue #7835: shelve should no longer produce mysterious warnings during
533 interpreter shutdown.
534
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000535- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
536 in XML processing instructions and comments. These raw characters are
537 allowed by the XML specification, and are necessary when outputting e.g.
538 PHP code in a processing instruction. Patch by Neil Muller.

550 type is specified. Patch by Brian Curtin.
551
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000552- Issue #6939: Fix file I/O objects in the `io` module to keep the original
553 file position when calling `truncate()`. It would previously change the
554 file position to the given argument, which goes against the tradition of
555 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
556
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000557- Issue #7610: Reworked implementation of the internal
558 :class:`zipfile.ZipExtFile` class used to represent files stored inside
559 an archive. The new implementation is significantly faster and can
560 be wrapped in a :class:`io.BufferedReader` object for more speedups.
561 It also solves an issue where interleaved calls to `read()` and
562 `readline()` give wrong results. Patch by Nir Aides.
563
Jesse Noller1f0b6582010-01-27 03:36:01 +0000564- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

566 the worker before that worker is terminated, and a new one created to
567 replace it.
568
Benjamin Petersond6326642010-01-27 02:25:58 +0000569- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000725- Issue #6816: runpy now provides a run_path function that allows Python code
726 to execute file paths that refer to source or compiled Python files as well
727 as zipfiles, directories and other valid sys.path entries that contain a
728 __main__.py file. This allows applications that run other Python scripts to
729 support the same flexibility as the CPython command line itself.
730

749 recursive locks as fast as regular non-recursive locks (previously,

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

1112
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001113- Issue #7712: test.support gained a new `temp_cwd` context manager which is

1135 user running the tests.
1136
R. David Murray35768ad2009-11-15 00:23:21 +00001137- Issue #7324: add a sanity check to regrtest argument parsing to

1142
Antoine Pitrou060cee22009-11-13 16:29:04 +00001143- Issue #6551: test_zipimport could import and then destroy some modules of

1145 the road because the internally cached encoders and decoders would point
1146 to empty global variables.
1147
Antoine Pitrou941ee882009-11-11 20:59:38 +00001148- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1160
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001161- Issue #7222: Make thread "reaping" more reliable so that reference
1162 leak-chasing test runs give sensible results. The previous method of
1163 reaping threads could return successfully while some Thread objects were
1164 still referenced. This also introduces a new private function:
1165 :func:`_thread._count()`.
1166
R. David Murray27144602009-10-19 15:26:16 +00001167- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1169
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001170- Issue #7055: test___all__ now greedily detects all modules which have an

1178
Brett Cannon3c273842009-07-20 00:14:29 +00001179- Fixed tests in importlib.test.source.test_abc_loader that were masking
1180 the proper exceptions that should be raised for missing or improper code
1181 object bytecode.
1182
Brett Cannonb49c70c2009-07-15 04:08:33 +00001183- Removed importlib's custom test discovery code and switched to

1373 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001454- Issue #5914: Add new C API function PyOS_string_to_double, and
1455 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1456
Eric Smith741191f2009-05-06 13:08:15 +00001457- Issue #3382: float.__format__, complex.__format__, and %-formatting
1458 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1459 affects nan -> NAN and inf -> INF.

Eric Smith63376222009-05-05 14:04:18 +00001465- Issue #5920: For float.__format__, change the behavior with the
1466 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1467 to be like 'g' but with at least one decimal point and with a
1468 default precision of 12. Previously, the behavior the same but with
1469 a default precision of 6. This more closely matches str(), and
1470 reduces surprises when adding alignment flags to the empty
1471 presentation type. This also affects the new complex.__format__ in
1472 the same way.

Martin v. Löwis011e8422009-05-05 04:43:17 +00001474- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001485- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1486 received a new method, detach(). detach() disconnects the underlying stream
1487 from the buffer or text IO and returns it.
1488
Mark Dickinson33841c32009-05-01 15:37:04 +00001489- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1490 floats with absolute value over 1e50. Also remove length
1491 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Eric Smith741191f2009-05-06 13:08:15 +00001494- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001495 format(complex(1, 2./3), '.5') now produces a sensible result.

Mark Dickinsond3ca5572009-04-29 18:47:07 +00001497- Issue #5864: Fix empty format code formatting for floats so that it
1498 never gives more than the requested number of significant digits.

1512
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001513- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001514
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001515- Issue #1869 (and many duplicates): make round(x, n) correctly
1516 rounded for a float x, by using the decimal <-> binary conversions
1517 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1518 consistently agrees with format(x, '.2f').
1519
Benjamin Petersonae937c02009-04-18 20:54:08 +00001520- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1522
Eric Smith0923d1d2009-04-16 20:16:10 +00001523- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1524
Eric Smith35e84722009-04-16 20:21:28 +00001525- Issue #5515: str.format() type 'n' combined with commas and leading
1526 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001527
1528- Implement PEP 378, Format Specifier for Thousands Separator, for
1529 floats.
1530
Mark Dickinson3370cce2009-04-17 22:40:53 +00001531- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001532 1e11, not 1e12. This avoids printing 13 significant digits in
1533 situations where only 12 of them are correct. Example problem
1534 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1535 long time.)
1536
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001537- Issue #1580: On most platforms, use a 'short' float repr: for a
1538 finite float x, repr(x) now outputs a string based on the shortest
1539 sequence of decimal digits that rounds to x. Previous behaviour was
1540 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001541 Another minor difference is that the new repr switches to
1542 exponential notation at 1e16 instead of the previous 1e17; this
1543 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001544
1545 There's a new sys attribute sys.float_repr_style, which takes
1546 the value 'short' to indicate that we're using short float repr,
1547 and 'legacy' if the short float repr isn't available for one
1548 reason or another.
1549
1550 The float repr change involves incorporating David Gay's 'perfect
1551 rounding' code into the Python core (it's in Python/dtoa.c). As a
1552 secondary consequence, all string-to-float and float-to-string
1553 conversions (including all float formatting operations) will be
1554 correctly rounded on these platforms.
1555
1556 See issue 1580 discussions for details of platforms for which
1557 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001559- Issue #5759: float() didn't call __float__ on str subclasses.
1560
Georg Brandlabc38772009-04-12 15:51:51 +00001561- The string.maketrans() function is deprecated; there is a new static method
1562 maketrans() on the bytes and bytearray classes. This removes confusion about
1563 the types string.maketrans() is supposed to work with, and mirrors the
1564 methods available on the str class.

1731 untrackable objects are not tracked by the garbage collector. This can
1732 reduce the size of collections and therefore the garbage collection overhead
1733 on long-running programs, depending on their particular use of datatypes.

1798 (typically /dev/zero under Unix) could crash the interpreter.
1799
Benjamin Peterson59406a92009-03-26 17:10:29 +00001800- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1802
Lars Gustäbel42e00912009-03-22 20:34:29 +00001803- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1804 forever on incomplete input. That caused tarfile.open() to hang when used
1805 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1806 partial bzip2 compressed data.
1807
Mark Dickinson79f52032009-03-17 23:12:51 +00001808- Issue #2110: Add support for thousands separator and 'n' type

1826 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001827 struct.error instead of returning b'\xff\xff\xff\xff'. The
1828 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1829 have been removed from the struct module.

1848 contained non ascii character on windows.
1849
Benjamin Petersonf5b52242009-03-02 23:31:26 +00001850- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
1851 source has already been decoded into str.
1852
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00001853- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
1854 rotating the object pointer by 4 bits to the right.
1855
Mark Dickinson87ec0852009-02-09 17:15:59 +00001856- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1857 it now forces its argument to double before testing for infinity.
1858
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001859- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1867 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001868
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001869- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001870 were suppressing all exceptions. These include list() and bytearray().
1871
Mark Dickinson1124e712009-01-28 21:25:58 +00001872- Issue #4707: round(x, n) now returns an integer if x is an integer.
1873 Previously it returned a float.
1874
Antoine Pitroub52ec782009-01-25 16:34:23 +00001875- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1876 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1877 evaluation loop is compiled with a new dispatch mechanism which gives
1878 speedups of up to 20%, depending on the system, on various benchmarks.
1879
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001880- Issue #4874: Most builtin decoders now reject unicode input.

1886
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001887- Issue #4838: When a module is deallocated, free the memory backing the
1888 optional module state data.
1889
Mark Dickinson8055afd2009-01-17 10:04:45 +00001890- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1891 type to (void *).
1892
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001893- Issue #4935: The overflow checking code in the expandtabs() method common
1894 to str, bytes and bytearray could be optimized away by the compiler, letting
1895 the interpreter segfault instead of raising an error.
1896
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001897- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1898 __next__ method.
1899
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001900- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1901 function no longer attempt to call the __long__ slot to convert an object
1902 to an integer. Only the __int__ and __trunc__ slots are examined.
1903
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001904- Issue #4893: Use NT threading on CE.
1905
Martin v. Löwisec59d042009-01-12 07:59:10 +00001906- Issue #4915: Port sysmodule to Windows CE.
1907
Antoine Pitrouab868312009-01-10 15:40:25 +00001908- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1909 common cases are optimized thanks to a dedicated fast path and a moderate
1910 amount of loop unrolling.
1911
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001912- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1913 collecting the oldest generation) so that allocating lots of objects without
1914 destroying them does not show quadratic performance. Based on a proposal by
1915 Martin von Löwis at
1916 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1917
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001918- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001919 having been closed (for instance, a read() call could return some
1920 previously buffered data). Patch by Dmitry Vasiliev.
1921
Antoine Pitrou05608432009-01-09 18:53:14 +00001922- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1923 flag to work properly. Furthermore, when specifying -u, the text stdout
1924 and stderr streams have line-by-line buffering enabled (the default being
1925 to buffer arbitrary chunks of data).
1926
Raymond Hettinger35631532009-01-09 03:58:09 +00001927- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1928 instead of ints (reducing its size from 4 to 8 times thereby reducing
1929 Python's overall memory).
1930
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001931- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1932 an existing .py counterpart, override the co_filename attributes of all
1933 code objects if the original filename is obsolete (which can happen if the
1934 file has been renamed, moved, or if it is accessed through different paths).
1935 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1936
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001937- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1938 one byte. Also fixes the meaning of len() so that it returns the number of
1939 items, rather than the size in bytes.
1940
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001941- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1942
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001943- Issue #4747: When the terminal does not use utf-8, executing a script with
1944 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1945
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001946- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001947 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001948
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001949- Issue #3680: Reference cycles created through a dict, set or deque iterator
1950 did not get collected.
1951
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001952- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1953 where the tp_hash and tp_dict slots are both NULL.
1954
Georg Brandlccc47b62008-12-28 11:44:14 +00001955- Issue #4759: None is now allowed as the first argument of
1956 bytearray.translate(). It was always allowed for bytes.translate().
1957
Skip Montanaro80072cb2008-12-23 03:51:14 +00001958- Added test case to ensure attempts to read from a file opened for writing
1959 fail.
1960
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001961- Issue #3106: Speedup some comparisons (str/str and int/int).

1965
Antoine Pitrou621601a2008-12-17 23:18:19 +00001966- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1967 print elapsed times, not only when some objects are uncollectable /
1968 unreachable. Original patch by Neil Schemenauer.
1969
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001970- Issue #3439: Add a bit_length method to int.
1971
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001972- Issue #2173: When getting device encoding, check that return value of
1973 nl_langinfo is not the empty string. This was causing silent build
1974 failures on OS X.
1975
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001976- Issue #4597: Fixed several opcodes that weren't always propagating
1977 exceptions.
1978
1979- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001980 context manager returns a value that cannot be converted to a bool.
1981
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001982- Issue #4445: Replace "sizeof(PyBytesObject)" with
1983 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1984 bytes instances. On a typical machine this saves 3 bytes of memory
1985 (on average) per allocation of a bytes instance.
1986
Christian Heimesa872de52008-12-05 08:26:55 +00001987- Issue #4533: File read operation was dreadfully slow due to a slowly
1988 growing read buffer. Fixed by using the same growth rate algorithm as
1989 Python 2.x.
1990
Antoine Pitrou5504e892008-12-06 21:27:53 +00001991- Issue #4509: Various issues surrounding resize of bytearray objects to
1992 which there are buffer exports (e.g. memoryview instances).
1993
Georg Brandlf9734072008-12-07 15:30:06 +00001994- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1995 method on file objects with closefd=False. The file descriptor is still
1996 kept open but the file object behaves like a closed file. The ``FileIO``
1997 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001998
Antoine Pitroubc420402008-12-07 20:14:49 +00001999- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2005
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002006- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2007 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2008 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2009 of using the replace error handler in PyUnicode_DecodeUTF8().
