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

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.

Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000326- Issue #4814: timeout parameter is now applied also for connections resulting
327 from PORT/EPRT commands.
328
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000329- Issue #8463: added missing reference to bztar in shutil's documentation.
330
Ronald Oussoren84151202010-04-18 20:46:11 +0000331- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
332 (as long as the user didn't specify 'automatic proxy configuration').

Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000334- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
335 code as stated in RFC-959 at chapter 5.4.
336
Victor Stinner738446f02010-04-18 00:00:44 +0000337- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
338 surrogates.
339
Antoine Pitrou0454af92010-04-17 23:51:58 +0000340- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000341 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

345
Victor Stinner0e59cc32010-04-16 23:49:32 +0000346- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
347 the current working directory.

359
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000360- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
361 module now takes an optional timeout argument in seconds. Timeout support
362 relies on the system threading library, so as to avoid a semi-busy wait
363 loop.
364
Victor Stinner485fb562010-04-13 11:07:24 +0000365- Issue #8383: pickle and pickletools use surrogatepass error handler when
366 encoding unicode as utf8 to support lone surrogates and stay compatible with
367 Python 2.x and 3.0
368
R. David Murrayb2416e52010-04-12 16:58:02 +0000369- Issue #7585: difflib context and unified diffs now place a tab between
370 filename and date, conforming to the 'standards' they were originally
371 designed to follow. This improves compatibility with patch tools.
372
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000373- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
374 character sets will now consistently use a Content-Transfer-Encoding of
375 7bit rather than sometimes being marked as 8bit.
376
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000377- Issue #8375: test_distutils now checks if the temporary directory are still
378 present before it cleans them.

384 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
385 and `ssl.OPENSSL_VERSION_NUMBER`.
386
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000387- Add functools.total_ordering() and functools.cmp_to_key().
388
Mark Dickinson089b00c2010-04-03 15:51:03 +0000389- Issue #8257: The Decimal construct now accepts a float instance
390 directly, converting that float to a Decimal of equal value:
391
392 >>> Decimal(1.1)
393 Decimal('1.100000000000000088817841970012523233890533447265625')
394
Mark Dickinson98127c32010-04-03 11:18:52 +0000395- Issue #8294: The Fraction constructor now accepts Decimal and float
396 instances directly.
397
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000398- Issue #7279: Comparisons involving a Decimal signaling NaN now
399 signal InvalidOperation instead of returning False. (Comparisons
400 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
401 are now hashable; Decimal signaling NaNs remain unhashable.
402
403- Issue #2531: Comparison operations between floats and Decimal
404 instances now return a result based on the numeric values of the
405 operands; previously they returned an arbitrary result based on
406 the relative ordering of id(float) and id(Decimal).
407
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000408- Added a subtract() method to collections.Counter().
409
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000410- Issue #8233: When run as a script, py_compile.py optionally takes a single
411 argument `-` which tells it to read files to compile from stdin. Each line
412 is read on demand and the named file is compiled immediately. (Original
413 patch by Piotr Ożarowski).
414
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000415- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
416 form feed (0x0C) are now considered linebreaks, as specified in Unicode
417 Standard Annex #14. See issue #7643.
418 http://www.unicode.org/reports/tr14/
419
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000420- Comparisons using one of <, <=, >, >= between a complex instance and
421 a Fractions instance now raise TypeError instead of returning
422 True/False. This makes Fraction <=> complex comparisons consistent with
423 int <=> complex, float <=> complex, and complex <=> complex comparisons.
424
Antoine Pitrou39b35432010-03-23 00:25:54 +0000425- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
426 some methods (such as oss_mixer_device.fileno()) were not available.
427 Initial patch by Bertrand Janin.
428
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000429- Issue #8205: Remove the "Modules" directory from sys.path when Python is
430 running from the build directory (POSIX only).
431
Antoine Pitrou910bd512010-03-22 20:11:09 +0000432- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
433 didn't support chflags() (for example ZFS under FreeBSD). The error is
434 now silenced.
435
R. David Murrayca2edce2010-03-22 17:48:48 +0000436- Issue #7860: platform.uname now reports the correct 'machine' type
437 when Python is running in WOW64 mode on 64 bit Windows.
438
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000439- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
440 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
441 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000442
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000443- Issue #4282: Fix the main function of the profile module for a non-ASCII
444 script, open the file in binary mode and not in text mode with the default
445 (utf8) encoding.
446
Florent Xicluna54467e02010-03-21 12:29:50 +0000447- Issue #8179: Fix macpath.realpath() on a non-existing path.
448

452
Benjamin Peterson689a5582010-03-18 22:29:52 +0000453- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
454 detected.
455
Martin v. Löwis4b003072010-03-16 13:19:21 +0000456- Issue #6716/2: Backslash-replace error output in compilall.
457
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000458- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
459 with Tcl/Tk-8.5.
460
Matthias Klosec33b9022010-03-16 00:36:26 +0000461- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000463- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
464 the locale.
465
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000466- The internals of the subprocess module on POSIX systems have been replaced
467 by an extension module (_posixsubprocess) so that the fork()+exec() can be
468 done safely without the possibility of deadlock in multithreaded applications.
469
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000470- subprocess.Popen now has restore_signals and start_new_session features.
471 The default of restore_signals=True is a new behavior compared to earlier
472 Python versions. This means that signals such as SIGPIPE are not ignored
473 by default in subprocesses launched by Python (Issue #1652).
474
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000475- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
476 cElementTree module is updated too.
477
Victor Stinnerb33062c2010-03-12 14:27:16 +0000478- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to

485 the replacement were all bytes. Patch by Antoine Pitrou.
486
Gerhard Häringf9cee222010-03-05 15:20:03 +0000487- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
488 bugs and allows loading SQLite extensions from shared libraries.
489

Victor Stinnercee3ae82010-03-04 00:29:24 +0000493- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
494 reset also the pointer to the current pointer context.
495
Lars Gustäbel01385812010-03-03 12:08:54 +0000496- Issue #7232: Add support for the context manager protocol to the TarFile

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000504- Issue #691291: codecs.open() should not convert end of lines on reading and
505 writing.
506
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000507- Issue #7869: logging: improved diagnostic for format-time errors.

521 to be ignored only to the first file. Noted by Bogdan Opanchuk.
522
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000523- Issue #7597: curses.use_env() can now be called before initscr().
524 Noted by Kan-Ru Chen.
525

532 bytecode file when it was less then 8 bytes.
533
Mark Dickinson84230a12010-02-18 14:49:50 +0000534- Issue #7633: In the decimal module, Context class methods (with the
535 exception of canonical and is_canonical) now accept instances of int
536 and long wherever a Decimal instance is accepted, and implicitly
537 convert that argument to Decimal. Previously only some arguments
538 were converted.
539
R. David Murray1f449142010-02-11 00:15:05 +0000540- Issue #7835: shelve should no longer produce mysterious warnings during
541 interpreter shutdown.
542
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000543- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
544 in XML processing instructions and comments. These raw characters are
545 allowed by the XML specification, and are necessary when outputting e.g.
546 PHP code in a processing instruction. Patch by Neil Muller.
547
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000548- Issue #6233: ElementTree failed converting unicode characters to XML

553 specify the compression type.
554
Antoine Pitroub6375f12010-02-04 20:23:24 +0000555- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

558 type is specified. Patch by Brian Curtin.
559
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000560- Issue #6939: Fix file I/O objects in the `io` module to keep the original
561 file position when calling `truncate()`. It would previously change the
562 file position to the given argument, which goes against the tradition of
563 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
564
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000565- Issue #7610: Reworked implementation of the internal
566 :class:`zipfile.ZipExtFile` class used to represent files stored inside
567 an archive. The new implementation is significantly faster and can
568 be wrapped in a :class:`io.BufferedReader` object for more speedups.
569 It also solves an issue where interleaved calls to `read()` and
570 `readline()` give wrong results. Patch by Nir Aides.
571
Jesse Noller1f0b6582010-01-27 03:36:01 +0000572- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
573 allowing for a maximum number of tasks within the pool to be completed by
574 the worker before that worker is terminated, and a new one created to
575 replace it.
576
Benjamin Petersond6326642010-01-27 02:25:58 +0000577- Issue #7792: Registering non-classes to ABCs raised an obscure error.
578
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000579- Issue #7785: Don't accept bytes in FileIO.write().

Ezio Melotti38f00332010-01-25 12:39:47 +0000581- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
582
Benjamin Peterson25001472010-01-25 03:37:42 +0000583- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

734 to execute file paths that refer to source or compiled Python files as well
735 as zipfiles, directories and other valid sys.path entries that contain a
736 __main__.py file. This allows applications that run other Python scripts to
737 support the same flexibility as the CPython command line itself.
738

757 recursive locks as fast as regular non-recursive locks (previously,
758 they were slower by 10x to 15x).

775 failures on systems with slightly bogus mtime behaviour.
776
Gregory P. Smith50467882009-11-01 18:42:17 +0000777- Issue #7246 & Issue #7208: getpass now properly flushes input before
778 reading from stdin so that existing input does not confuse it and

1170 leak-chasing test runs give sensible results. The previous method of
1171 reaping threads could return successfully while some Thread objects were
1172 still referenced. This also introduces a new private function:
1173 :func:`_thread._count()`.
1174
R. David Murray27144602009-10-19 15:26:16 +00001175- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1177
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001178- Issue #7055: test___all__ now greedily detects all modules which have an

1186
Brett Cannon3c273842009-07-20 00:14:29 +00001187- Fixed tests in importlib.test.source.test_abc_loader that were masking
1188 the proper exceptions that should be raised for missing or improper code
1189 object bytecode.
1190
Brett Cannonb49c70c2009-07-15 04:08:33 +00001191- Removed importlib's custom test discovery code and switched to

Mark Dickinson865e01a2009-05-07 16:37:01 +00001462- Issue #5914: Add new C API function PyOS_string_to_double, and
1463 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1464
Eric Smith741191f2009-05-06 13:08:15 +00001465- Issue #3382: float.__format__, complex.__format__, and %-formatting
1466 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1467 affects nan -> NAN and inf -> INF.
1468

1472
Eric Smith63376222009-05-05 14:04:18 +00001473- Issue #5920: For float.__format__, change the behavior with the
1474 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1475 to be like 'g' but with at least one decimal point and with a
1476 default precision of 12. Previously, the behavior the same but with
1477 a default precision of 6. This more closely matches str(), and
1478 reduces surprises when adding alignment flags to the empty
1479 presentation type. This also affects the new complex.__format__ in
1480 the same way.
1481
Martin v. Löwis011e8422009-05-05 04:43:17 +00001482- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001493- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1494 received a new method, detach(). detach() disconnects the underlying stream
1495 from the buffer or text IO and returns it.
1496
Mark Dickinson33841c32009-05-01 15:37:04 +00001497- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1498 floats with absolute value over 1e50. Also remove length
1499 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1500 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001502- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001503 format(complex(1, 2./3), '.5') now produces a sensible result.
1504
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001505- Issue #5864: Fix empty format code formatting for floats so that it
1506 never gives more than the requested number of significant digits.
1507
Eric Smith6dc46f52009-04-27 20:39:49 +00001508- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1515
Benjamin Peterson193152c2009-04-25 01:08:45 +00001516- Issue #5283: Setting __class__ in __del__ caused a segfault.

1520
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001521- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001522
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001523- Issue #1869 (and many duplicates): make round(x, n) correctly
1524 rounded for a float x, by using the decimal <-> binary conversions
1525 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1526 consistently agrees with format(x, '.2f').
1527
Benjamin Petersonae937c02009-04-18 20:54:08 +00001528- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1530
Eric Smith0923d1d2009-04-16 20:16:10 +00001531- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1532
Eric Smith35e84722009-04-16 20:21:28 +00001533- Issue #5515: str.format() type 'n' combined with commas and leading
1534 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001535
1536- Implement PEP 378, Format Specifier for Thousands Separator, for
1537 floats.
1538
Mark Dickinson3370cce2009-04-17 22:40:53 +00001539- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001540 1e11, not 1e12. This avoids printing 13 significant digits in
1541 situations where only 12 of them are correct. Example problem
1542 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1543 long time.)
1544
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001545- Issue #1580: On most platforms, use a 'short' float repr: for a
1546 finite float x, repr(x) now outputs a string based on the shortest
1547 sequence of decimal digits that rounds to x. Previous behaviour was
1548 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001549 Another minor difference is that the new repr switches to
1550 exponential notation at 1e16 instead of the previous 1e17; this
1551 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001552
1553 There's a new sys attribute sys.float_repr_style, which takes
1554 the value 'short' to indicate that we're using short float repr,
1555 and 'legacy' if the short float repr isn't available for one
1556 reason or another.
1557
1558 The float repr change involves incorporating David Gay's 'perfect
1559 rounding' code into the Python core (it's in Python/dtoa.c). As a
1560 secondary consequence, all string-to-float and float-to-string
1561 conversions (including all float formatting operations) will be
1562 correctly rounded on these platforms.
1563
1564 See issue 1580 discussions for details of platforms for which
1565 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001567- Issue #5759: float() didn't call __float__ on str subclasses.
1568
Georg Brandlabc38772009-04-12 15:51:51 +00001569- The string.maketrans() function is deprecated; there is a new static method
1570 maketrans() on the bytes and bytearray classes. This removes confusion about
1571 the types string.maketrans() is supposed to work with, and mirrors the
1572 methods available on the str class.

1739 untrackable objects are not tracked by the garbage collector. This can
1740 reduce the size of collections and therefore the garbage collection overhead
1741 on long-running programs, depending on their particular use of datatypes.

1798
Jesse Noller7af4ef82009-03-30 16:47:15 +00001799- Issue #5177: Multiprocessing's SocketListener class now uses

1806 (typically /dev/zero under Unix) could crash the interpreter.
1807
Benjamin Peterson59406a92009-03-26 17:10:29 +00001808- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

1810
Lars Gustäbel42e00912009-03-22 20:34:29 +00001811- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1812 forever on incomplete input. That caused tarfile.open() to hang when used
1813 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1814 partial bzip2 compressed data.
1815
Mark Dickinson79f52032009-03-17 23:12:51 +00001816- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001835 struct.error instead of returning b'\xff\xff\xff\xff'. The
1836 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

1862 rotating the object pointer by 4 bits to the right.
1863
Mark Dickinson87ec0852009-02-09 17:15:59 +00001864- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1865 it now forces its argument to double before testing for infinity.
1866
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001867- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

1875 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001876
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001877- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001878 were suppressing all exceptions. These include list() and bytearray().
1879
Mark Dickinson1124e712009-01-28 21:25:58 +00001880- Issue #4707: round(x, n) now returns an integer if x is an integer.
1881 Previously it returned a float.
1882
Antoine Pitroub52ec782009-01-25 16:34:23 +00001883- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1884 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1885 evaluation loop is compiled with a new dispatch mechanism which gives
1886 speedups of up to 20%, depending on the system, on various benchmarks.
1887
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001888- Issue #4874: Most builtin decoders now reject unicode input.

1894
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001895- Issue #4838: When a module is deallocated, free the memory backing the
1896 optional module state data.
1897
Mark Dickinson8055afd2009-01-17 10:04:45 +00001898- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1899 type to (void *).
1900
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001901- Issue #4935: The overflow checking code in the expandtabs() method common
1902 to str, bytes and bytearray could be optimized away by the compiler, letting
1903 the interpreter segfault instead of raising an error.
1904
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001905- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1906 __next__ method.
1907
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001908- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1909 function no longer attempt to call the __long__ slot to convert an object
1910 to an integer. Only the __int__ and __trunc__ slots are examined.
1911
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001912- Issue #4893: Use NT threading on CE.
1913
Martin v. Löwisec59d042009-01-12 07:59:10 +00001914- Issue #4915: Port sysmodule to Windows CE.
1915
Antoine Pitrouab868312009-01-10 15:40:25 +00001916- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1917 common cases are optimized thanks to a dedicated fast path and a moderate
1918 amount of loop unrolling.
1919
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001920- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1921 collecting the oldest generation) so that allocating lots of objects without
1922 destroying them does not show quadratic performance. Based on a proposal by
1923 Martin von Löwis at
1924 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1925
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001926- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001927 having been closed (for instance, a read() call could return some
1928 previously buffered data). Patch by Dmitry Vasiliev.
1929
Antoine Pitrou05608432009-01-09 18:53:14 +00001930- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1931 flag to work properly. Furthermore, when specifying -u, the text stdout
1932 and stderr streams have line-by-line buffering enabled (the default being
1933 to buffer arbitrary chunks of data).
1934
Raymond Hettinger35631532009-01-09 03:58:09 +00001935- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1936 instead of ints (reducing its size from 4 to 8 times thereby reducing
1937 Python's overall memory).
1938
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001939- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1940 an existing .py counterpart, override the co_filename attributes of all
1941 code objects if the original filename is obsolete (which can happen if the
1942 file has been renamed, moved, or if it is accessed through different paths).
1943 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1944
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001945- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1946 one byte. Also fixes the meaning of len() so that it returns the number of
1947 items, rather than the size in bytes.
1948
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001949- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1950
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001951- Issue #4747: When the terminal does not use utf-8, executing a script with
1952 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1953
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001954- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001955 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001956
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001957- Issue #3680: Reference cycles created through a dict, set or deque iterator
1958 did not get collected.
1959
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001960- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1961 where the tp_hash and tp_dict slots are both NULL.
1962
Georg Brandlccc47b62008-12-28 11:44:14 +00001963- Issue #4759: None is now allowed as the first argument of
1964 bytearray.translate(). It was always allowed for bytes.translate().
1965
Skip Montanaro80072cb2008-12-23 03:51:14 +00001966- Added test case to ensure attempts to read from a file opened for writing
1967 fail.
1968
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001969- Issue #3106: Speedup some comparisons (str/str and int/int).

1972 comprehensions. Original patch for list comprehensions by Neal Norwitz.
1973
Antoine Pitrou621601a2008-12-17 23:18:19 +00001974- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1975 print elapsed times, not only when some objects are uncollectable /
1976 unreachable. Original patch by Neil Schemenauer.
1977
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001978- Issue #3439: Add a bit_length method to int.
1979
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001980- Issue #2173: When getting device encoding, check that return value of
1981 nl_langinfo is not the empty string. This was causing silent build
1982 failures on OS X.
1983
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001984- Issue #4597: Fixed several opcodes that weren't always propagating
1985 exceptions.
1986
1987- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001988 context manager returns a value that cannot be converted to a bool.
1989
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001990- Issue #4445: Replace "sizeof(PyBytesObject)" with
1991 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1992 bytes instances. On a typical machine this saves 3 bytes of memory
1993 (on average) per allocation of a bytes instance.
1994
Christian Heimesa872de52008-12-05 08:26:55 +00001995- Issue #4533: File read operation was dreadfully slow due to a slowly
1996 growing read buffer. Fixed by using the same growth rate algorithm as
1997 Python 2.x.
1998
Antoine Pitrou5504e892008-12-06 21:27:53 +00001999- Issue #4509: Various issues surrounding resize of bytearray objects to
2000 which there are buffer exports (e.g. memoryview instances).
2001
Georg Brandlf9734072008-12-07 15:30:06 +00002002- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2003 method on file objects with closefd=False. The file descriptor is still
2004 kept open but the file object behaves like a closed file. The ``FileIO``
2005 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002006
Antoine Pitroubc420402008-12-07 20:14:49 +00002007- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002014- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2015 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2016 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2017 of using the replace error handler in PyUnicode_DecodeUTF8().
