21 changed.
22
Mark Dickinson3318d292010-04-06 16:53:17 +000023- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
24 on 64-bit machines. The shift count for either left or right shift is

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()
107 methods of bytes, bytearray and unicode objects by using a common
108 implementation based on stringlib's fast search. Patch by Florent Xicluna.

Mark Dickinson45b63652010-01-16 18:10:25 +0000110- Issue #7632: Fix various str -> float conversion bugs present in 2.7
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
163 several cases where reversed(range(a, b, c)) gave wrong results, and
164 fix a refleak for reversed(range(a, b, c)) with large arguments.

205 and include information from the Unihan.txt file.
206
Mark Dickinson2683ab02009-09-29 19:21:35 +0000207- Issue #7019: Raise ValueError when unmarshalling bad long data, instead
208 of producing internally inconsistent Python longs.

Victor Stinner5bfe1462010-04-16 13:28:05 +0000318- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
319 using backslashreplace error handler
320
Victor Stinnercfa72782010-04-16 11:45:13 +0000321- Issue #8412: os.system() now accepts bytes, bytearray and str with
322 surrogates.
323
Senthil Kumaranad02d232010-04-16 03:02:13 +0000324- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
325 Locke and Hans Ulrich Niedermann.
326
R. David Murrayd48739f2010-04-14 18:59:18 +0000327- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
328
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000329- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
330 module now takes an optional timeout argument in seconds. Timeout support
331 relies on the system threading library, so as to avoid a semi-busy wait
332 loop.
333
Victor Stinner485fb562010-04-13 11:07:24 +0000334- Issue #8383: pickle and pickletools use surrogatepass error handler when
335 encoding unicode as utf8 to support lone surrogates and stay compatible with
336 Python 2.x and 3.0
337
R. David Murrayb2416e52010-04-12 16:58:02 +0000338- Issue #7585: difflib context and unified diffs now place a tab between
339 filename and date, conforming to the 'standards' they were originally
340 designed to follow. This improves compatibility with patch tools.
341
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000342- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
343 character sets will now consistently use a Content-Transfer-Encoding of
344 7bit rather than sometimes being marked as 8bit.
345
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000346- Issue #8375: test_distutils now checks if the temporary directory are still
347 present before it cleans them.
348
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000349- Issue #8374: Update the internal alias table in the :mod:`locale` module
350 to cover recent locale changes and additions.
351
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000352- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
353 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
354 and `ssl.OPENSSL_VERSION_NUMBER`.
355
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000356- Add functools.total_ordering() and functools.cmp_to_key().
357
Mark Dickinson089b00c2010-04-03 15:51:03 +0000358- Issue #8257: The Decimal construct now accepts a float instance
359 directly, converting that float to a Decimal of equal value:
360
361 >>> Decimal(1.1)
362 Decimal('1.100000000000000088817841970012523233890533447265625')
363
Mark Dickinson98127c32010-04-03 11:18:52 +0000364- Issue #8294: The Fraction constructor now accepts Decimal and float
365 instances directly.
366
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000367- Issue #7279: Comparisons involving a Decimal signaling NaN now
368 signal InvalidOperation instead of returning False. (Comparisons
369 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
370 are now hashable; Decimal signaling NaNs remain unhashable.
371
372- Issue #2531: Comparison operations between floats and Decimal
373 instances now return a result based on the numeric values of the
374 operands; previously they returned an arbitrary result based on
375 the relative ordering of id(float) and id(Decimal).
376
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000377- Added a subtract() method to collections.Counter().
378
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000379- Issue #8233: When run as a script, py_compile.py optionally takes a single
380 argument `-` which tells it to read files to compile from stdin. Each line
381 is read on demand and the named file is compiled immediately. (Original
382 patch by Piotr Ożarowski).
383
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000384- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
385 form feed (0x0C) are now considered linebreaks, as specified in Unicode
386 Standard Annex #14. See issue #7643.
387 http://www.unicode.org/reports/tr14/
388
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000389- Comparisons using one of <, <=, >, >= between a complex instance and
390 a Fractions instance now raise TypeError instead of returning
391 True/False. This makes Fraction <=> complex comparisons consistent with
392 int <=> complex, float <=> complex, and complex <=> complex comparisons.
393
Antoine Pitrou39b35432010-03-23 00:25:54 +0000394- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
395 some methods (such as oss_mixer_device.fileno()) were not available.
396 Initial patch by Bertrand Janin.
397
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000398- Issue #8205: Remove the "Modules" directory from sys.path when Python is
399 running from the build directory (POSIX only).
400
Antoine Pitrou910bd512010-03-22 20:11:09 +0000401- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
402 didn't support chflags() (for example ZFS under FreeBSD). The error is
403 now silenced.
404
R. David Murrayca2edce2010-03-22 17:48:48 +0000405- Issue #7860: platform.uname now reports the correct 'machine' type
406 when Python is running in WOW64 mode on 64 bit Windows.
407
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000408- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
409 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
410 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000411
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000412- Issue #4282: Fix the main function of the profile module for a non-ASCII
413 script, open the file in binary mode and not in text mode with the default
414 (utf8) encoding.
415
Florent Xicluna54467e02010-03-21 12:29:50 +0000416- Issue #8179: Fix macpath.realpath() on a non-existing path.
417
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000418- Issue #8024: Update the Unicode database to 5.2.
419
Benjamin Peterson00888932010-03-18 22:37:38 +0000420- Issue #8168: py_compile now handles files with utf-8 BOMS.
421
Benjamin Peterson689a5582010-03-18 22:29:52 +0000422- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
423 detected.
424
Martin v. Löwis4b003072010-03-16 13:19:21 +0000425- Issue #6716/2: Backslash-replace error output in compilall.
426
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000427- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
428 with Tcl/Tk-8.5.
429
Matthias Klosec33b9022010-03-16 00:36:26 +0000430- Issue #8140: extend compileall to compile single files. Add -i option.
431
Matthias Klose82f60912010-03-15 13:46:04 +0000432- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
433 the locale.
434
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000435- The internals of the subprocess module on POSIX systems have been replaced
436 by an extension module (_posixsubprocess) so that the fork()+exec() can be
437 done safely without the possibility of deadlock in multithreaded applications.
438
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000439- subprocess.Popen now has restore_signals and start_new_session features.
440 The default of restore_signals=True is a new behavior compared to earlier
441 Python versions. This means that signals such as SIGPIPE are not ignored
442 by default in subprocesses launched by Python (Issue #1652).
443
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000444- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
445 cElementTree module is updated too.

454 the replacement were all bytes. Patch by Antoine Pitrou.
455
Gerhard Häringf9cee222010-03-05 15:20:03 +0000456- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
457 bugs and allows loading SQLite extensions from shared libraries.
458
Ezio Melottida227042010-03-14 11:51:00 +0000459- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public
460 Review Issue #29 (http://unicode.org/review/pr-29.html).
Victor Stinner7ed9c4c2010-03-04 12:14:57 +0000461
Victor Stinnercee3ae82010-03-04 00:29:24 +0000462- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
463 reset also the pointer to the current pointer context.

472
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000473- Issue #691291: codecs.open() should not convert end of lines on reading and
474 writing.
475
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000476- Issue #7869: logging: improved diagnostic for format-time errors.

Thomas Heller5117b0b2010-02-23 20:25:02 +0000484- Issue #7959: ctypes callback functions are now registered correctly
Ezio Melotti8b1458b2010-02-24 16:55:43 +0000485 with the cycle garbage collector.
Thomas Heller5117b0b2010-02-23 20:25:02 +0000486

490 to be ignored only to the first file. Noted by Bogdan Opanchuk.
491
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000492- Issue #7597: curses.use_env() can now be called before initscr().
493 Noted by Kan-Ru Chen.
494

501 bytecode file when it was less then 8 bytes.
502
Mark Dickinson84230a12010-02-18 14:49:50 +0000503- Issue #7633: In the decimal module, Context class methods (with the
504 exception of canonical and is_canonical) now accept instances of int
505 and long wherever a Decimal instance is accepted, and implicitly
506 convert that argument to Decimal. Previously only some arguments
507 were converted.
508
R. David Murray1f449142010-02-11 00:15:05 +0000509- Issue #7835: shelve should no longer produce mysterious warnings during
510 interpreter shutdown.
511
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000512- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
513 in XML processing instructions and comments. These raw characters are
514 allowed by the XML specification, and are necessary when outputting e.g.
515 PHP code in a processing instruction. Patch by Neil Muller.
516
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000517- Issue #6233: ElementTree failed converting unicode characters to XML

527 type is specified. Patch by Brian Curtin.
528
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000529- Issue #6939: Fix file I/O objects in the `io` module to keep the original
530 file position when calling `truncate()`. It would previously change the
531 file position to the given argument, which goes against the tradition of
532 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
533
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000534- Issue #7610: Reworked implementation of the internal
535 :class:`zipfile.ZipExtFile` class used to represent files stored inside
536 an archive. The new implementation is significantly faster and can
537 be wrapped in a :class:`io.BufferedReader` object for more speedups.
538 It also solves an issue where interleaved calls to `read()` and
539 `readline()` give wrong results. Patch by Nir Aides.
540
Jesse Noller1f0b6582010-01-27 03:36:01 +0000541- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
542 allowing for a maximum number of tasks within the pool to be completed by
543 the worker before that worker is terminated, and a new one created to
544 replace it.
545
Benjamin Petersond6326642010-01-27 02:25:58 +0000546- Issue #7792: Registering non-classes to ABCs raised an obscure error.
547

701
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000702- Issue #6816: runpy now provides a run_path function that allows Python code
703 to execute file paths that refer to source or compiled Python files as well
704 as zipfiles, directories and other valid sys.path entries that contain a
705 __main__.py file. This allows applications that run other Python scripts to
706 support the same flexibility as the CPython command line itself.
707
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000708- Issue #7318: multiprocessing now uses a timeout when it fails to establish

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

743 a modification is done through it. This fixes inconsistencies and test
744 failures on systems with slightly bogus mtime behaviour.
745
Gregory P. Smith50467882009-11-01 18:42:17 +0000746- Issue #7246 & Issue #7208: getpass now properly flushes input before
747 reading from stdin so that existing input does not confuse it and
748 lead to incorrect entry or an IOError. It also properly flushes it
749 afterwards to avoid the terminal echoing the input afterwards on
750 OSes such as Solaris.

1137
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001138- Issue #7222: Make thread "reaping" more reliable so that reference
1139 leak-chasing test runs give sensible results. The previous method of
1140 reaping threads could return successfully while some Thread objects were
1141 still referenced. This also introduces a new private function:
1142 :func:`_thread._count()`.
1143
R. David Murray27144602009-10-19 15:26:16 +00001144- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1146
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001147- Issue #7055: test___all__ now greedily detects all modules which have an

1155
Brett Cannon3c273842009-07-20 00:14:29 +00001156- Fixed tests in importlib.test.source.test_abc_loader that were masking
1157 the proper exceptions that should be raised for missing or improper code

Antoine Pitrou61f77b52009-05-24 15:46:13 +00001349- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1350 than an int, which makes some operations possible under 64-bit Linux (e.g.
1351 DN_MULTISHOT with F_NOTIFY).
1352
Antoine Pitrou716c4442009-05-23 19:04:03 +00001353- Issue #5761: Add the name of the underlying file to the repr() of various

Mark Dickinson865e01a2009-05-07 16:37:01 +00001431- Issue #5914: Add new C API function PyOS_string_to_double, and
1432 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1433
Eric Smith741191f2009-05-06 13:08:15 +00001434- Issue #3382: float.__format__, complex.__format__, and %-formatting
1435 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1436 affects nan -> NAN and inf -> INF.
1437
Mark Hammond5a607a32009-05-06 08:04:54 +00001438- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1439 in all operations, including splitdrive, split, etc. splitunc() now issues

Eric Smith63376222009-05-05 14:04:18 +00001442- Issue #5920: For float.__format__, change the behavior with the
1443 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1444 to be like 'g' but with at least one decimal point and with a
1445 default precision of 12. Previously, the behavior the same but with
1446 a default precision of 6. This more closely matches str(), and
1447 reduces surprises when adding alignment flags to the empty
1448 presentation type. This also affects the new complex.__format__ in
1449 the same way.
1450
Martin v. Löwis011e8422009-05-05 04:43:17 +00001451- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1463 received a new method, detach(). detach() disconnects the underlying stream
1464 from the buffer or text IO and returns it.
1465
Mark Dickinson33841c32009-05-01 15:37:04 +00001466- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1467 floats with absolute value over 1e50. Also remove length
1468 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

1488 z involves nans, infs or negative zeros.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001492- Issue #1869 (and many duplicates): make round(x, n) correctly
1493 rounded for a float x, by using the decimal <-> binary conversions
1494 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now

Benjamin Petersonae937c02009-04-18 20:54:08 +00001497- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1498 some builtin types.
1499
Eric Smith0923d1d2009-04-16 20:16:10 +00001500- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1501
Eric Smith35e84722009-04-16 20:21:28 +00001502- Issue #5515: str.format() type 'n' combined with commas and leading
1503 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001504
1505- Implement PEP 378, Format Specifier for Thousands Separator, for
1506 floats.
1507
Mark Dickinson3370cce2009-04-17 22:40:53 +00001508- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001509 1e11, not 1e12. This avoids printing 13 significant digits in
1510 situations where only 12 of them are correct. Example problem
1511 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1512 long time.)
1513
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001514- Issue #1580: On most platforms, use a 'short' float repr: for a
1515 finite float x, repr(x) now outputs a string based on the shortest
1516 sequence of decimal digits that rounds to x. Previous behaviour was
1517 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001518 Another minor difference is that the new repr switches to
1519 exponential notation at 1e16 instead of the previous 1e17; this
1520 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001521
1522 There's a new sys attribute sys.float_repr_style, which takes
1523 the value 'short' to indicate that we're using short float repr,
1524 and 'legacy' if the short float repr isn't available for one
1525 reason or another.
1526
1527 The float repr change involves incorporating David Gay's 'perfect
1528 rounding' code into the Python core (it's in Python/dtoa.c). As a
1529 secondary consequence, all string-to-float and float-to-string
1530 conversions (including all float formatting operations) will be
1531 correctly rounded on these platforms.
1532
1533 See issue 1580 discussions for details of platforms for which
1534 this change does not apply.
1535
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001536- Issue #5759: float() didn't call __float__ on str subclasses.
1537
Georg Brandlabc38772009-04-12 15:51:51 +00001538- The string.maketrans() function is deprecated; there is a new static method
1539 maketrans() on the bytes and bytearray classes. This removes confusion about
1540 the types string.maketrans() is supposed to work with, and mirrors the
1541 methods available on the str class.
1542
R. David Murraydc6da8a2009-04-09 22:16:43 +00001543- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1708 untrackable objects are not tracked by the garbage collector. This can
1709 reduce the size of collections and therefore the garbage collection overhead
1710 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonae681df2009-03-21 10:26:31 +00001802- Issue #5463: In struct module, remove deprecated overflow wrapping
1803 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00001804 struct.error instead of returning b'\xff\xff\xff\xff'. The
1805 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1806 have been removed from the struct module.

1831 rotating the object pointer by 4 bits to the right.
1832
Mark Dickinson87ec0852009-02-09 17:15:59 +00001833- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1834 it now forces its argument to double before testing for infinity.
1835
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001836- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001845
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001846- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001847 were suppressing all exceptions. These include list() and bytearray().

1851
Antoine Pitroub52ec782009-01-25 16:34:23 +00001852- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1853 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1854 evaluation loop is compiled with a new dispatch mechanism which gives
1855 speedups of up to 20%, depending on the system, on various benchmarks.
1856
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001857- Issue #4874: Most builtin decoders now reject unicode input.

1863
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001864- Issue #4838: When a module is deallocated, free the memory backing the
1865 optional module state data.
1866
Mark Dickinson8055afd2009-01-17 10:04:45 +00001867- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1868 type to (void *).
1869
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001870- Issue #4935: The overflow checking code in the expandtabs() method common
1871 to str, bytes and bytearray could be optimized away by the compiler, letting
1872 the interpreter segfault instead of raising an error.
1873
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001874- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1875 __next__ method.
1876
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001877- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1878 function no longer attempt to call the __long__ slot to convert an object
1879 to an integer. Only the __int__ and __trunc__ slots are examined.
1880
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001881- Issue #4893: Use NT threading on CE.
1882

1884
Antoine Pitrouab868312009-01-10 15:40:25 +00001885- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1886 common cases are optimized thanks to a dedicated fast path and a moderate
1887 amount of loop unrolling.
1888
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001889- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1890 collecting the oldest generation) so that allocating lots of objects without
1891 destroying them does not show quadratic performance. Based on a proposal by
1892 Martin von Löwis at
1893 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1894
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001895- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001896 having been closed (for instance, a read() call could return some
1897 previously buffered data). Patch by Dmitry Vasiliev.
1898
Antoine Pitrou05608432009-01-09 18:53:14 +00001899- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1900 flag to work properly. Furthermore, when specifying -u, the text stdout
1901 and stderr streams have line-by-line buffering enabled (the default being
1902 to buffer arbitrary chunks of data).
1903
Raymond Hettinger35631532009-01-09 03:58:09 +00001904- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1905 instead of ints (reducing its size from 4 to 8 times thereby reducing
1906 Python's overall memory).
1907
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001908- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1909 an existing .py counterpart, override the co_filename attributes of all
1910 code objects if the original filename is obsolete (which can happen if the
1911 file has been renamed, moved, or if it is accessed through different paths).
1912 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1913
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001914- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1915 one byte. Also fixes the meaning of len() so that it returns the number of
1916 items, rather than the size in bytes.
1917
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001918- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1919
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001920- Issue #4747: When the terminal does not use utf-8, executing a script with
1921 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1922
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001923- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001924 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001925
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001926- Issue #3680: Reference cycles created through a dict, set or deque iterator
1927 did not get collected.
1928
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001929- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1930 where the tp_hash and tp_dict slots are both NULL.
1931
Georg Brandlccc47b62008-12-28 11:44:14 +00001932- Issue #4759: None is now allowed as the first argument of
1933 bytearray.translate(). It was always allowed for bytes.translate().
1934
Skip Montanaro80072cb2008-12-23 03:51:14 +00001935- Added test case to ensure attempts to read from a file opened for writing
1936 fail.
1937
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00001938- Issue #3106: Speedup some comparisons (str/str and int/int).

1942
Antoine Pitrou621601a2008-12-17 23:18:19 +00001943- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
1944 print elapsed times, not only when some objects are uncollectable /
1945 unreachable. Original patch by Neil Schemenauer.
1946
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00001947- Issue #3439: Add a bit_length method to int.
1948
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001949- Issue #2173: When getting device encoding, check that return value of
1950 nl_langinfo is not the empty string. This was causing silent build
1951 failures on OS X.
1952
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001953- Issue #4597: Fixed several opcodes that weren't always propagating
1954 exceptions.
1955
1956- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001957 context manager returns a value that cannot be converted to a bool.
1958
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001959- Issue #4445: Replace "sizeof(PyBytesObject)" with
1960 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1961 bytes instances. On a typical machine this saves 3 bytes of memory
1962 (on average) per allocation of a bytes instance.
1963
Christian Heimesa872de52008-12-05 08:26:55 +00001964- Issue #4533: File read operation was dreadfully slow due to a slowly
1965 growing read buffer. Fixed by using the same growth rate algorithm as
1966 Python 2.x.
1967
Antoine Pitrou5504e892008-12-06 21:27:53 +00001968- Issue #4509: Various issues surrounding resize of bytearray objects to
1969 which there are buffer exports (e.g. memoryview instances).
1970
Georg Brandlf9734072008-12-07 15:30:06 +00001971- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1972 method on file objects with closefd=False. The file descriptor is still
1973 kept open but the file object behaves like a closed file. The ``FileIO``
1974 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001975
Antoine Pitroubc420402008-12-07 20:14:49 +00001976- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1982
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001983- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1984 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1985 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1986 of using the replace error handler in PyUnicode_DecodeUTF8().
