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

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

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

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

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

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

Victor Stinnercfa72782010-04-16 11:45:13 +0000315- Issue #8412: os.system() now accepts bytes, bytearray and str with
316 surrogates.
317
Senthil Kumaranad02d232010-04-16 03:02:13 +0000318- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
319 Locke and Hans Ulrich Niedermann.
320
R. David Murrayd48739f2010-04-14 18:59:18 +0000321- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
322
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000323- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
324 module now takes an optional timeout argument in seconds. Timeout support
325 relies on the system threading library, so as to avoid a semi-busy wait
326 loop.
327
Victor Stinner485fb562010-04-13 11:07:24 +0000328- Issue #8383: pickle and pickletools use surrogatepass error handler when
329 encoding unicode as utf8 to support lone surrogates and stay compatible with
330 Python 2.x and 3.0
331
R. David Murrayb2416e52010-04-12 16:58:02 +0000332- Issue #7585: difflib context and unified diffs now place a tab between
333 filename and date, conforming to the 'standards' they were originally
334 designed to follow. This improves compatibility with patch tools.
335
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000336- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
337 character sets will now consistently use a Content-Transfer-Encoding of
338 7bit rather than sometimes being marked as 8bit.
339
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000340- Issue #8375: test_distutils now checks if the temporary directory are still
341 present before it cleans them.
342
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000343- Issue #8374: Update the internal alias table in the :mod:`locale` module
344 to cover recent locale changes and additions.
345
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000346- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
347 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
348 and `ssl.OPENSSL_VERSION_NUMBER`.
349
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000350- Add functools.total_ordering() and functools.cmp_to_key().
351
Mark Dickinson089b00c2010-04-03 15:51:03 +0000352- Issue #8257: The Decimal construct now accepts a float instance
353 directly, converting that float to a Decimal of equal value:
354
355 >>> Decimal(1.1)
356 Decimal('1.100000000000000088817841970012523233890533447265625')
357
Mark Dickinson98127c32010-04-03 11:18:52 +0000358- Issue #8294: The Fraction constructor now accepts Decimal and float
359 instances directly.
360
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000361- Issue #7279: Comparisons involving a Decimal signaling NaN now
362 signal InvalidOperation instead of returning False. (Comparisons
363 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
364 are now hashable; Decimal signaling NaNs remain unhashable.
365
366- Issue #2531: Comparison operations between floats and Decimal
367 instances now return a result based on the numeric values of the
368 operands; previously they returned an arbitrary result based on
369 the relative ordering of id(float) and id(Decimal).
370
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000371- Added a subtract() method to collections.Counter().
372
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000373- Issue #8233: When run as a script, py_compile.py optionally takes a single
374 argument `-` which tells it to read files to compile from stdin. Each line
375 is read on demand and the named file is compiled immediately. (Original
376 patch by Piotr Ożarowski).
377
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000378- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
379 form feed (0x0C) are now considered linebreaks, as specified in Unicode
380 Standard Annex #14. See issue #7643.
381 http://www.unicode.org/reports/tr14/
382
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000383- Comparisons using one of <, <=, >, >= between a complex instance and
384 a Fractions instance now raise TypeError instead of returning
385 True/False. This makes Fraction <=> complex comparisons consistent with
386 int <=> complex, float <=> complex, and complex <=> complex comparisons.
387
Antoine Pitrou39b35432010-03-23 00:25:54 +0000388- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
389 some methods (such as oss_mixer_device.fileno()) were not available.
390 Initial patch by Bertrand Janin.
391
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000392- Issue #8205: Remove the "Modules" directory from sys.path when Python is
393 running from the build directory (POSIX only).
394
Antoine Pitrou910bd512010-03-22 20:11:09 +0000395- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
396 didn't support chflags() (for example ZFS under FreeBSD). The error is
397 now silenced.
398
R. David Murrayca2edce2010-03-22 17:48:48 +0000399- Issue #7860: platform.uname now reports the correct 'machine' type
400 when Python is running in WOW64 mode on 64 bit Windows.
401
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000402- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
403 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
404 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000405
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000406- Issue #4282: Fix the main function of the profile module for a non-ASCII
407 script, open the file in binary mode and not in text mode with the default
408 (utf8) encoding.
409
Florent Xicluna54467e02010-03-21 12:29:50 +0000410- Issue #8179: Fix macpath.realpath() on a non-existing path.
411
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000412- Issue #8024: Update the Unicode database to 5.2.
413
Benjamin Peterson00888932010-03-18 22:37:38 +0000414- Issue #8168: py_compile now handles files with utf-8 BOMS.
415
Benjamin Peterson689a5582010-03-18 22:29:52 +0000416- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
417 detected.
418
Martin v. Löwis4b003072010-03-16 13:19:21 +0000419- Issue #6716/2: Backslash-replace error output in compilall.
420
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000421- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
422 with Tcl/Tk-8.5.
423
Matthias Klosec33b9022010-03-16 00:36:26 +0000424- Issue #8140: extend compileall to compile single files. Add -i option.
425
Matthias Klose82f60912010-03-15 13:46:04 +0000426- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
427 the locale.
428
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000429- The internals of the subprocess module on POSIX systems have been replaced
430 by an extension module (_posixsubprocess) so that the fork()+exec() can be
431 done safely without the possibility of deadlock in multithreaded applications.
432
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000433- subprocess.Popen now has restore_signals and start_new_session features.
434 The default of restore_signals=True is a new behavior compared to earlier
435 Python versions. This means that signals such as SIGPIPE are not ignored
436 by default in subprocesses launched by Python (Issue #1652).
437
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000438- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
439 cElementTree module is updated too.
440

448 the replacement were all bytes. Patch by Antoine Pitrou.
449
Gerhard Häringf9cee222010-03-05 15:20:03 +0000450- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
451 bugs and allows loading SQLite extensions from shared libraries.
452
Ezio Melottida227042010-03-14 11:51:00 +0000453- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public
454 Review Issue #29 (http://unicode.org/review/pr-29.html).
Victor Stinner7ed9c4c2010-03-04 12:14:57 +0000455
Victor Stinnercee3ae82010-03-04 00:29:24 +0000456- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
457 reset also the pointer to the current pointer context.

466
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000467- Issue #691291: codecs.open() should not convert end of lines on reading and
468 writing.
469
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000470- Issue #7869: logging: improved diagnostic for format-time errors.

484 to be ignored only to the first file. Noted by Bogdan Opanchuk.
485
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000486- Issue #7597: curses.use_env() can now be called before initscr().
487 Noted by Kan-Ru Chen.
488

498 exception of canonical and is_canonical) now accept instances of int
499 and long wherever a Decimal instance is accepted, and implicitly
500 convert that argument to Decimal. Previously only some arguments
501 were converted.
502
R. David Murray1f449142010-02-11 00:15:05 +0000503- Issue #7835: shelve should no longer produce mysterious warnings during
504 interpreter shutdown.
505
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000506- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
507 in XML processing instructions and comments. These raw characters are
508 allowed by the XML specification, and are necessary when outputting e.g.
509 PHP code in a processing instruction. Patch by Neil Muller.
510

521 type is specified. Patch by Brian Curtin.
522
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000523- Issue #6939: Fix file I/O objects in the `io` module to keep the original
524 file position when calling `truncate()`. It would previously change the
525 file position to the given argument, which goes against the tradition of
526 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
527
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000528- Issue #7610: Reworked implementation of the internal
529 :class:`zipfile.ZipExtFile` class used to represent files stored inside
530 an archive. The new implementation is significantly faster and can
531 be wrapped in a :class:`io.BufferedReader` object for more speedups.
532 It also solves an issue where interleaved calls to `read()` and
533 `readline()` give wrong results. Patch by Nir Aides.
534
Jesse Noller1f0b6582010-01-27 03:36:01 +0000535- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
536 allowing for a maximum number of tasks within the pool to be completed by
537 the worker before that worker is terminated, and a new one created to
538 replace it.
539
Benjamin Petersond6326642010-01-27 02:25:58 +0000540- Issue #7792: Registering non-classes to ABCs raised an obscure error.
541
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000542- Issue #7785: Don't accept bytes in FileIO.write().

Ezio Melotti38f00332010-01-25 12:39:47 +0000544- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
545
Benjamin Peterson25001472010-01-25 03:37:42 +0000546- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

Ezio Melottifaa6b7f2009-12-30 12:34:59 +0000597- Issue #5511: now zipfile.ZipFile can be used as a context manager.
598 Initial patch by Brian Curtin.
599
Tarek Ziadéc60ea322009-12-21 23:12:41 +0000600- Issue #7556: Make sure Distutils' msvc9compile reads and writes the

617 the same as passing no argument.
618
Lars Gustäbel365aff32009-12-13 11:42:29 +0000619- Issue #7357: tarfile no longer suppresses fatal extraction errors by

697 to execute file paths that refer to source or compiled Python files as well
698 as zipfiles, directories and other valid sys.path entries that contain a
699 __main__.py file. This allows applications that run other Python scripts to
700 support the same flexibility as the CPython command line itself.
701
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000702- Issue #7318: multiprocessing now uses a timeout when it fails to establish

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

738 failures on systems with slightly bogus mtime behaviour.
739
Gregory P. Smith50467882009-11-01 18:42:17 +0000740- Issue #7246 & Issue #7208: getpass now properly flushes input before
741 reading from stdin so that existing input does not confuse it and
742 lead to incorrect entry or an IOError. It also properly flushes it
743 afterwards to avoid the terminal echoing the input afterwards on
744 OSes such as Solaris.

1131
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001132- Issue #7222: Make thread "reaping" more reliable so that reference
1133 leak-chasing test runs give sensible results. The previous method of
1134 reaping threads could return successfully while some Thread objects were
1135 still referenced. This also introduces a new private function:
1136 :func:`_thread._count()`.
1137
R. David Murray27144602009-10-19 15:26:16 +00001138- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1139 longer runs the risk of causing the worker thread to fail.
1140
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001141- Issue #7055: test___all__ now greedily detects all modules which have an

Mark Dickinson2e304402009-10-04 18:43:54 +00001148- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1149
Brett Cannon3c273842009-07-20 00:14:29 +00001150- Fixed tests in importlib.test.source.test_abc_loader that were masking
1151 the proper exceptions that should be raised for missing or improper code

Antoine Pitrou61f77b52009-05-24 15:46:13 +00001343- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1344 than an int, which makes some operations possible under 64-bit Linux (e.g.

1423-----------------
1424
Mark Dickinson865e01a2009-05-07 16:37:01 +00001425- Issue #5914: Add new C API function PyOS_string_to_double, and
1426 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1427
Eric Smith741191f2009-05-06 13:08:15 +00001428- Issue #3382: float.__format__, complex.__format__, and %-formatting
1429 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1430 affects nan -> NAN and inf -> INF.
1431
Mark Hammond5a607a32009-05-06 08:04:54 +00001432- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1433 in all operations, including splitdrive, split, etc. splitunc() now issues
1434 a PendingDeprecation warning.
1435
Eric Smith63376222009-05-05 14:04:18 +00001436- Issue #5920: For float.__format__, change the behavior with the
1437 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1438 to be like 'g' but with at least one decimal point and with a
1439 default precision of 12. Previously, the behavior the same but with
1440 a default precision of 6. This more closely matches str(), and
1441 reduces surprises when adding alignment flags to the empty
1442 presentation type. This also affects the new complex.__format__ in
1443 the same way.
1444
Martin v. Löwis011e8422009-05-05 04:43:17 +00001445- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1453
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001454- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001456- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1457 received a new method, detach(). detach() disconnects the underlying stream
1458 from the buffer or text IO and returns it.
1459
Mark Dickinson33841c32009-05-01 15:37:04 +00001460- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1461 floats with absolute value over 1e50. Also remove length
1462 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

Mark Dickinsond3ca5572009-04-29 18:47:07 +00001468- Issue #5864: Fix empty format code formatting for floats so that it
1469 never gives more than the requested number of significant digits.
1470
Eric Smith6dc46f52009-04-27 20:39:49 +00001471- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001486- Issue #1869 (and many duplicates): make round(x, n) correctly
1487 rounded for a float x, by using the decimal <-> binary conversions
1488 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1489 consistently agrees with format(x, '.2f').
1490
Benjamin Petersonae937c02009-04-18 20:54:08 +00001491- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1492 some builtin types.

Eric Smith0923d1d2009-04-16 20:16:10 +00001494- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1495
Eric Smith35e84722009-04-16 20:21:28 +00001496- Issue #5515: str.format() type 'n' combined with commas and leading
1497 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001498
1499- Implement PEP 378, Format Specifier for Thousands Separator, for
1500 floats.
1501
Mark Dickinson3370cce2009-04-17 22:40:53 +00001502- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001503 1e11, not 1e12. This avoids printing 13 significant digits in
1504 situations where only 12 of them are correct. Example problem
1505 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1506 long time.)
1507
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001508- Issue #1580: On most platforms, use a 'short' float repr: for a
1509 finite float x, repr(x) now outputs a string based on the shortest
1510 sequence of decimal digits that rounds to x. Previous behaviour was
1511 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001512 Another minor difference is that the new repr switches to
1513 exponential notation at 1e16 instead of the previous 1e17; this
1514 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001515
1516 There's a new sys attribute sys.float_repr_style, which takes
1517 the value 'short' to indicate that we're using short float repr,
1518 and 'legacy' if the short float repr isn't available for one
1519 reason or another.
1520
1521 The float repr change involves incorporating David Gay's 'perfect
1522 rounding' code into the Python core (it's in Python/dtoa.c). As a
1523 secondary consequence, all string-to-float and float-to-string
1524 conversions (including all float formatting operations) will be
1525 correctly rounded on these platforms.
1526
1527 See issue 1580 discussions for details of platforms for which
1528 this change does not apply.
1529
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001530- Issue #5759: float() didn't call __float__ on str subclasses.
1531
Georg Brandlabc38772009-04-12 15:51:51 +00001532- The string.maketrans() function is deprecated; there is a new static method
1533 maketrans() on the bytes and bytearray classes. This removes confusion about
1534 the types string.maketrans() is supposed to work with, and mirrors the
1535 methods available on the str class.
1536
R. David Murraydc6da8a2009-04-09 22:16:43 +00001537- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1702 untrackable objects are not tracked by the garbage collector. This can
1703 reduce the size of collections and therefore the garbage collection overhead
1704 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00001798 struct.error instead of returning b'\xff\xff\xff\xff'. The
1799 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
1800 have been removed from the struct module.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001839
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001840- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001841 were suppressing all exceptions. These include list() and bytearray().

1847 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1848 evaluation loop is compiled with a new dispatch mechanism which gives
1849 speedups of up to 20%, depending on the system, on various benchmarks.
1850

1859 optional module state data.
1860
Mark Dickinson8055afd2009-01-17 10:04:45 +00001861- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1862 type to (void *).
1863
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001864- Issue #4935: The overflow checking code in the expandtabs() method common
1865 to str, bytes and bytearray could be optimized away by the compiler, letting
1866 the interpreter segfault instead of raising an error.
1867
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001868- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1869 __next__ method.
1870
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001871- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1872 function no longer attempt to call the __long__ slot to convert an object
1873 to an integer. Only the __int__ and __trunc__ slots are examined.
1874
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001875- Issue #4893: Use NT threading on CE.

1878
Antoine Pitrouab868312009-01-10 15:40:25 +00001879- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1880 common cases are optimized thanks to a dedicated fast path and a moderate
1881 amount of loop unrolling.
1882
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001883- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1884 collecting the oldest generation) so that allocating lots of objects without
1885 destroying them does not show quadratic performance. Based on a proposal by
1886 Martin von Löwis at
1887 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1888
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001889- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001890 having been closed (for instance, a read() call could return some
1891 previously buffered data). Patch by Dmitry Vasiliev.
1892
Antoine Pitrou05608432009-01-09 18:53:14 +00001893- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1894 flag to work properly. Furthermore, when specifying -u, the text stdout
1895 and stderr streams have line-by-line buffering enabled (the default being
1896 to buffer arbitrary chunks of data).
1897
Raymond Hettinger35631532009-01-09 03:58:09 +00001898- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1899 instead of ints (reducing its size from 4 to 8 times thereby reducing
1900 Python's overall memory).
1901
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001902- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1903 an existing .py counterpart, override the co_filename attributes of all
1904 code objects if the original filename is obsolete (which can happen if the
1905 file has been renamed, moved, or if it is accessed through different paths).
1906 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1907
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001908- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1909 one byte. Also fixes the meaning of len() so that it returns the number of
1910 items, rather than the size in bytes.
1911
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001912- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1913
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001914- Issue #4747: When the terminal does not use utf-8, executing a script with
1915 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1916
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001917- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001918 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001919
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001920- Issue #3680: Reference cycles created through a dict, set or deque iterator
1921 did not get collected.
1922
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001923- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1924 where the tp_hash and tp_dict slots are both NULL.
1925
Georg Brandlccc47b62008-12-28 11:44:14 +00001926- Issue #4759: None is now allowed as the first argument of
1927 bytearray.translate(). It was always allowed for bytes.translate().
1928
Skip Montanaro80072cb2008-12-23 03:51:14 +00001929- Added test case to ensure attempts to read from a file opened for writing
1930 fail.
1931

1942
Mark Dickinsonda2706b2008-12-11 18:03:03 +00001943- Issue #2173: When getting device encoding, check that return value of
1944 nl_langinfo is not the empty string. This was causing silent build
1945 failures on OS X.
1946
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00001947- Issue #4597: Fixed several opcodes that weren't always propagating
1948 exceptions.
1949
1950- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00001951 context manager returns a value that cannot be converted to a bool.
1952
Mark Dickinsonfd24b322008-12-06 15:33:31 +00001953- Issue #4445: Replace "sizeof(PyBytesObject)" with
1954 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
1955 bytes instances. On a typical machine this saves 3 bytes of memory
1956 (on average) per allocation of a bytes instance.
1957
Christian Heimesa872de52008-12-05 08:26:55 +00001958- Issue #4533: File read operation was dreadfully slow due to a slowly
1959 growing read buffer. Fixed by using the same growth rate algorithm as
1960 Python 2.x.
1961
Antoine Pitrou5504e892008-12-06 21:27:53 +00001962- Issue #4509: Various issues surrounding resize of bytearray objects to
1963 which there are buffer exports (e.g. memoryview instances).
1964
Georg Brandlf9734072008-12-07 15:30:06 +00001965- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
1966 method on file objects with closefd=False. The file descriptor is still
1967 kept open but the file object behaves like a closed file. The ``FileIO``
1968 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00001969
Antoine Pitroubc420402008-12-07 20:14:49 +00001970- Issue #4569: Interpreter crash when mutating a memoryview with an item size

1976
Walter Dörwaldc1651a02009-05-03 22:55:55 +00001977- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
1978 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
1979 step. This avoids problems with counting UTF-8 bytes that ignores the effect
1980 of using the replace error handler in PyUnicode_DecodeUTF8().
