27 benefit compared to the dynamic memory allocation fallback. Patch by
28 Charles-François Natali.
29
Benjamin Peterson8380dd52010-04-16 22:51:37 +000030- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

99
Mark Dickinsonbc099642010-01-29 17:27:24 +0000100- Issue #7788: Fix an interpreter crash produced by deleting a list
101 slice with very large step value.
102
Eric Smithf7bb5782010-01-27 00:44:57 +0000103- Issue #7766: Change sys.getwindowsversion() return value to a named
104 tuple and add the additional members returned in an OSVERSIONINFOEX
105 structure. The new members are service_pack_major, service_pack_minor,
106 suite_mask, and product_type.
107
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000108- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
109 could crash in many places because of the PyByteArray_AS_STRING() macro
110 returning NULL. The macro now returns a statically allocated empty
111 string instead.
112
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000113- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
114 where the right hand operand is a set of constants, by turning the set into
115 a frozenset and pre-building it as a constant. The comparison operation
116 is made against the constant instead of building a new set each time it is
117 executed (a similar optimization already existed which turned a list of
118 constants into a pre-built tuple). Patch and additional tests by Dave
119 Malcolm.
120
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000121- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

123 implementation based on stringlib's fast search. Patch by Florent Xicluna.
124
Mark Dickinson45b63652010-01-16 18:10:25 +0000125- Issue #7632: Fix various str -> float conversion bugs present in 2.7
126 alpha 2, including: (1) a serious 'wrong output' bug that could
127 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
128 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000129 strings corresponding to subnormal values, (3) a memory leak for
130 some values large enough to cause overflow, and (4) a number of
131 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000132
Benjamin Petersonaea44282010-01-04 01:10:28 +0000133- The __complex__ method is now looked up on the class of instances to make it

143 negative zero) in ** operator. The behaviour now conforms to that
144 described in C99 Annex F.
145
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000146- Issue #1811: improve accuracy and cross-platform consistency for
147 true division of integers: the result of a/b is now correctly
148 rounded for ints a and b (at least on IEEE 754 platforms), and in
149 particular does not depend on the internal representation of an int.
150
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000151- Issue #6834: replace the implementation for the 'python' and 'pythonw'
152 executables on OSX.
153
154 These executables now work properly with the arch(1) command:
155 ``arch -ppc python`` will start a universal binary version of python
156 in PPC mode (unlike previous releases).
157
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000158- Issue #7466: segmentation fault when the garbage collector is called

174
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000175- Issue #7298: fixes for range and reversed(range(...)). Iteration
176 over range(a, b, c) incorrectly gave an empty iterator when a, b and
177 c fit in C long but the length of the range did not. Also fix
178 several cases where reversed(range(a, b, c)) gave wrong results, and

320 PyCode_Addr2Line().
321
322- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
323 object at a specified file, function, and line number.
324
325- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
326 ``const char *`` as the string is stored beyond the call.
327
Benjamin Peterson05159c42009-12-03 03:01:27 +0000328- Issue #2422: When compiled with the ``--with-valgrind`` option, the
329 pymalloc allocator will be automatically disabled when running under
330 Valgrind. This gives improved memory leak detection when running
331 under Valgrind, while taking advantage of pymalloc at other times.

341
Sean Reifscheider13daf122010-04-23 09:29:52 +0000342- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
343 the string "python" as the *ident*. openlog() arguments are all optional
344 and keywords.
345
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000346- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
347 a non-infinite timeout. Also make that method friendlier with applications
348 wanting to continue using the socket in clear-text mode, by disabling
349 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
350
Antoine Pitrou7062db82010-04-22 13:30:10 +0000351- Issue #8496: make mailcap.lookup() always return a list, rather than an
352 iterator. Patch by Gregory Nofi.

Victor Stinner35466c52010-04-22 11:23:23 +0000354- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
355 collation name contains a surrogate character.
356
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000357- Issue #8484: Load all ciphers and digest algorithms when initializing
358 the _ssl extension, such that verification of some SSL certificates
359 doesn't fail because of an "unknown algorithm".
360
Tarek Ziadéfb437512010-04-20 08:57:33 +0000361- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.

Tarek Ziadé5340db32010-04-19 22:30:51 +0000363- Issue #1540112: Now allowing the choice of a copy function in
364 shutil.copytree.
365
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000366- Issue #4814: timeout parameter is now applied also for connections resulting
367 from PORT/EPRT commands.
368
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000369- Issue #8463: added missing reference to bztar in shutil's documentation.
370
Ronald Oussoren84151202010-04-18 20:46:11 +0000371- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6

375 code as stated in RFC-959 at chapter 5.4.
376
Victor Stinner738446f02010-04-18 00:00:44 +0000377- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
378 surrogates.
379
Antoine Pitrou0454af92010-04-17 23:51:58 +0000380- Issue #850728: Add a *timeout* parameter to the `acquire()` method of

399
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000400- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
401 module now takes an optional timeout argument in seconds. Timeout support
402 relies on the system threading library, so as to avoid a semi-busy wait
403 loop.
404
Victor Stinner485fb562010-04-13 11:07:24 +0000405- Issue #8383: pickle and pickletools use surrogatepass error handler when
406 encoding unicode as utf8 to support lone surrogates and stay compatible with
407 Python 2.x and 3.0
408
R. David Murrayb2416e52010-04-12 16:58:02 +0000409- Issue #7585: difflib context and unified diffs now place a tab between
410 filename and date, conforming to the 'standards' they were originally
411 designed to follow. This improves compatibility with patch tools.
412
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000413- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
414 character sets will now consistently use a Content-Transfer-Encoding of
415 7bit rather than sometimes being marked as 8bit.
416
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000417- Issue #8375: test_distutils now checks if the temporary directory are still
418 present before it cleans them.
419

424 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
425 and `ssl.OPENSSL_VERSION_NUMBER`.
426
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000427- Add functools.total_ordering() and functools.cmp_to_key().
428
Mark Dickinson089b00c2010-04-03 15:51:03 +0000429- Issue #8257: The Decimal construct now accepts a float instance
430 directly, converting that float to a Decimal of equal value:
431
432 >>> Decimal(1.1)
433 Decimal('1.100000000000000088817841970012523233890533447265625')
434
Mark Dickinson98127c32010-04-03 11:18:52 +0000435- Issue #8294: The Fraction constructor now accepts Decimal and float
436 instances directly.
437
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000438- Issue #7279: Comparisons involving a Decimal signaling NaN now
439 signal InvalidOperation instead of returning False. (Comparisons
440 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
441 are now hashable; Decimal signaling NaNs remain unhashable.
442
443- Issue #2531: Comparison operations between floats and Decimal
444 instances now return a result based on the numeric values of the
445 operands; previously they returned an arbitrary result based on
446 the relative ordering of id(float) and id(Decimal).
447
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000448- Added a subtract() method to collections.Counter().
449
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000450- Issue #8233: When run as a script, py_compile.py optionally takes a single
451 argument `-` which tells it to read files to compile from stdin. Each line
452 is read on demand and the named file is compiled immediately. (Original
453 patch by Piotr Ożarowski).
454
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000455- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
456 form feed (0x0C) are now considered linebreaks, as specified in Unicode
457 Standard Annex #14. See issue #7643.
458 http://www.unicode.org/reports/tr14/
459
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000460- Comparisons using one of <, <=, >, >= between a complex instance and
461 a Fractions instance now raise TypeError instead of returning
462 True/False. This makes Fraction <=> complex comparisons consistent with
463 int <=> complex, float <=> complex, and complex <=> complex comparisons.
464
Antoine Pitrou39b35432010-03-23 00:25:54 +0000465- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
466 some methods (such as oss_mixer_device.fileno()) were not available.
467 Initial patch by Bertrand Janin.
468
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000469- Issue #8205: Remove the "Modules" directory from sys.path when Python is
470 running from the build directory (POSIX only).
471
Antoine Pitrou910bd512010-03-22 20:11:09 +0000472- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
473 didn't support chflags() (for example ZFS under FreeBSD). The error is
474 now silenced.
475
R. David Murrayca2edce2010-03-22 17:48:48 +0000476- Issue #7860: platform.uname now reports the correct 'machine' type
477 when Python is running in WOW64 mode on 64 bit Windows.
478
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000479- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
480 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
481 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000482
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000483- Issue #4282: Fix the main function of the profile module for a non-ASCII
484 script, open the file in binary mode and not in text mode with the default
485 (utf8) encoding.
486
Florent Xicluna54467e02010-03-21 12:29:50 +0000487- Issue #8179: Fix macpath.realpath() on a non-existing path.

490
Benjamin Peterson00888932010-03-18 22:37:38 +0000491- Issue #8168: py_compile now handles files with utf-8 BOMS.
492
Benjamin Peterson689a5582010-03-18 22:29:52 +0000493- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
494 detected.
495
Martin v. Löwis4b003072010-03-16 13:19:21 +0000496- Issue #6716/2: Backslash-replace error output in compilall.
497
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000498- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
499 with Tcl/Tk-8.5.
500
Matthias Klosec33b9022010-03-16 00:36:26 +0000501- Issue #8140: extend compileall to compile single files. Add -i option.
502
Matthias Klose82f60912010-03-15 13:46:04 +0000503- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
504 the locale.
505
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000506- The internals of the subprocess module on POSIX systems have been replaced
507 by an extension module (_posixsubprocess) so that the fork()+exec() can be
508 done safely without the possibility of deadlock in multithreaded applications.
509
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000510- subprocess.Popen now has restore_signals and start_new_session features.
511 The default of restore_signals=True is a new behavior compared to earlier
512 Python versions. This means that signals such as SIGPIPE are not ignored
513 by default in subprocesses launched by Python (Issue #1652).
514
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000515- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
516 cElementTree module is updated too.
517

525 the replacement were all bytes. Patch by Antoine Pitrou.
526
Gerhard Häringf9cee222010-03-05 15:20:03 +0000527- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
528 bugs and allows loading SQLite extensions from shared libraries.

Victor Stinnercee3ae82010-03-04 00:29:24 +0000533- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
534 reset also the pointer to the current pointer context.
535

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000544- Issue #691291: codecs.open() should not convert end of lines on reading and
545 writing.
546
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000547- Issue #7869: logging: improved diagnostic for format-time errors.

Thomas Heller5117b0b2010-02-23 20:25:02 +0000555- Issue #7959: ctypes callback functions are now registered correctly
Ezio Melotti8b1458b2010-02-24 16:55:43 +0000556 with the cycle garbage collector.
Thomas Heller5117b0b2010-02-23 20:25:02 +0000557

559
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000560- Issue #6666: fix bug in trace.py that applied the list of directories
561 to be ignored only to the first file. Noted by Bogdan Opanchuk.
562
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000563- Issue #7597: curses.use_env() can now be called before initscr().
564 Noted by Kan-Ru Chen.
565
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000566- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

569 messages parsed by email.Parser.HeaderParser.
570
Brett Cannonef7d6722010-02-19 16:04:36 +0000571- Issue #7361: Importlib was not properly checking the number of bytes in
572 bytecode file when it was less then 8 bytes.
573
Mark Dickinson84230a12010-02-18 14:49:50 +0000574- Issue #7633: In the decimal module, Context class methods (with the
575 exception of canonical and is_canonical) now accept instances of int
576 and long wherever a Decimal instance is accepted, and implicitly
577 convert that argument to Decimal. Previously only some arguments
578 were converted.
579
R. David Murray1f449142010-02-11 00:15:05 +0000580- Issue #7835: shelve should no longer produce mysterious warnings during
581 interpreter shutdown.
582
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000583- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
584 in XML processing instructions and comments. These raw characters are
585 allowed by the XML specification, and are necessary when outputting e.g.
586 PHP code in a processing instruction. Patch by Neil Muller.
587
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000588- Issue #6233: ElementTree failed converting unicode characters to XML

593 specify the compression type.
594
Antoine Pitroub6375f12010-02-04 20:23:24 +0000595- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

598 type is specified. Patch by Brian Curtin.
599
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000600- Issue #6939: Fix file I/O objects in the `io` module to keep the original
601 file position when calling `truncate()`. It would previously change the
602 file position to the given argument, which goes against the tradition of
603 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
604
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000605- Issue #7610: Reworked implementation of the internal
606 :class:`zipfile.ZipExtFile` class used to represent files stored inside
607 an archive. The new implementation is significantly faster and can
608 be wrapped in a :class:`io.BufferedReader` object for more speedups.
609 It also solves an issue where interleaved calls to `read()` and
610 `readline()` give wrong results. Patch by Nir Aides.
611
Jesse Noller1f0b6582010-01-27 03:36:01 +0000612- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
613 allowing for a maximum number of tasks within the pool to be completed by
614 the worker before that worker is terminated, and a new one created to
615 replace it.
616
Benjamin Petersond6326642010-01-27 02:25:58 +0000617- Issue #7792: Registering non-classes to ABCs raised an obscure error.

R. David Murray83396232009-12-14 22:45:15 +00001197 instead of a hardcoded port number in test_rapid_restart.
1198
R. David Murrayba311052009-12-04 00:09:14 +00001199- Issue #7431: use TESTFN in test_linecache instead of trying to create a
1200 file in the Lib/test directory, which might be read-only for the
1201 user running the tests.
1202
R. David Murray35768ad2009-11-15 00:23:21 +00001203- Issue #7324: add a sanity check to regrtest argument parsing to
1204 catch the case of an option with no handler.
1205
R. David Murray7dc72cc2009-11-14 16:13:02 +00001206- Issue #7312: Add a -F flag to run the selected tests in a loop until
1207 a test fails. Can be combined with -j.
1208
Antoine Pitrou060cee22009-11-13 16:29:04 +00001209- Issue #6551: test_zipimport could import and then destroy some modules of
1210 the encodings package, which would make other tests fail further down
1211 the road because the internally cached encoders and decoders would point
1212 to empty global variables.
1213
Antoine Pitrou941ee882009-11-11 20:59:38 +00001214- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1225 calling methods on the object.
1226
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001227- Issue #7222: Make thread "reaping" more reliable so that reference
1228 leak-chasing test runs give sensible results. The previous method of
1229 reaping threads could return successfully while some Thread objects were
1230 still referenced. This also introduces a new private function:
1231 :func:`_thread._count()`.
1232
R. David Murray27144602009-10-19 15:26:16 +00001233- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1234 longer runs the risk of causing the worker thread to fail.
1235
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001236- Issue #7055: test___all__ now greedily detects all modules which have an
1237 __all__ attribute, rather than using a hardcoded and incomplete list.
1238
R. David Murray0bc11ae2009-10-18 22:18:17 +00001239- Issue #7058: Added save/restore for things like sys.argv and cwd to

1241 and a new section in the summary report at the end.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001516
1517Core and Builtins
1518-----------------
1519
Mark Dickinson865e01a2009-05-07 16:37:01 +00001520- Issue #5914: Add new C API function PyOS_string_to_double, and
1521 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1522
Eric Smith741191f2009-05-06 13:08:15 +00001523- Issue #3382: float.__format__, complex.__format__, and %-formatting
1524 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1525 affects nan -> NAN and inf -> INF.
1526
Mark Hammond5a607a32009-05-06 08:04:54 +00001527- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1528 in all operations, including splitdrive, split, etc. splitunc() now issues
1529 a PendingDeprecation warning.
1530
Eric Smith63376222009-05-05 14:04:18 +00001531- Issue #5920: For float.__format__, change the behavior with the
1532 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1533 to be like 'g' but with at least one decimal point and with a
1534 default precision of 12. Previously, the behavior the same but with
1535 a default precision of 6. This more closely matches str(), and
1536 reduces surprises when adding alignment flags to the empty
1537 presentation type. This also affects the new complex.__format__ in
1538 the same way.
1539
Martin v. Löwis011e8422009-05-05 04:43:17 +00001540- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1541
R. David Murrayb18500d2009-05-04 22:59:07 +00001542- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1543 shadowed by classtype's, even if it was None. property now
1544 inserts the __doc__ into the subclass instance __dict__.
1545
Antoine Pitrou244651a2009-05-04 18:56:13 +00001546- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1547 sequences. Patch by Nick Barnes and Victor Stinner.
1548
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001549- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001550
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001551- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1552 received a new method, detach(). detach() disconnects the underlying stream
1553 from the buffer or text IO and returns it.
1554
Mark Dickinson33841c32009-05-01 15:37:04 +00001555- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1556 floats with absolute value over 1e50. Also remove length
1557 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1558 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001559
Eric Smith741191f2009-05-06 13:08:15 +00001560- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001561 format(complex(1, 2./3), '.5') now produces a sensible result.
1562
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001563- Issue #5864: Fix empty format code formatting for floats so that it
1564 never gives more than the requested number of significant digits.
1565
Eric Smith6dc46f52009-04-27 20:39:49 +00001566- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1567 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1568
Eric Smithcc32a112009-04-26 21:35:14 +00001569- Issue #5835: Deprecate PyOS_ascii_formatd.
1570
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001571- Issue #4971: Fix titlecase for characters that are their own
1572 titlecase, but not their own uppercase.
1573
Benjamin Peterson193152c2009-04-25 01:08:45 +00001574- Issue #5283: Setting __class__ in __del__ caused a segfault.
1575
Mark Dickinsonad476da2009-04-23 19:14:16 +00001576- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1577 z involves nans, infs or negative zeros.
1578
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001579- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001580
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001581- Issue #1869 (and many duplicates): make round(x, n) correctly
1582 rounded for a float x, by using the decimal <-> binary conversions
1583 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1584 consistently agrees with format(x, '.2f').
1585
Benjamin Petersonae937c02009-04-18 20:54:08 +00001586- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1587 some builtin types.
1588
Eric Smith0923d1d2009-04-16 20:16:10 +00001589- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1590
Eric Smith35e84722009-04-16 20:21:28 +00001591- Issue #5515: str.format() type 'n' combined with commas and leading
1592 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001593
1594- Implement PEP 378, Format Specifier for Thousands Separator, for
1595 floats.
1596
Mark Dickinson3370cce2009-04-17 22:40:53 +00001597- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001598 1e11, not 1e12. This avoids printing 13 significant digits in
1599 situations where only 12 of them are correct. Example problem
1600 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1601 long time.)
1602
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001603- Issue #1580: On most platforms, use a 'short' float repr: for a
1604 finite float x, repr(x) now outputs a string based on the shortest
1605 sequence of decimal digits that rounds to x. Previous behaviour was
1606 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001607 Another minor difference is that the new repr switches to
1608 exponential notation at 1e16 instead of the previous 1e17; this
1609 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001610
1611 There's a new sys attribute sys.float_repr_style, which takes
1612 the value 'short' to indicate that we're using short float repr,
1613 and 'legacy' if the short float repr isn't available for one
1614 reason or another.
1615
1616 The float repr change involves incorporating David Gay's 'perfect
1617 rounding' code into the Python core (it's in Python/dtoa.c). As a
1618 secondary consequence, all string-to-float and float-to-string
1619 conversions (including all float formatting operations) will be
1620 correctly rounded on these platforms.
1621
1622 See issue 1580 discussions for details of platforms for which
1623 this change does not apply.
1624
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001625- Issue #5759: float() didn't call __float__ on str subclasses.
1626
Georg Brandlabc38772009-04-12 15:51:51 +00001627- The string.maketrans() function is deprecated; there is a new static method
1628 maketrans() on the bytes and bytearray classes. This removes confusion about
1629 the types string.maketrans() is supposed to work with, and mirrors the
1630 methods available on the str class.
1631
R. David Murraydc6da8a2009-04-09 22:16:43 +00001632- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1633 its clarity and its speed.
1634
Matthias Klose091c7b12009-04-07 13:24:27 +00001635- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1636 to avoid compiler warnings.
1637
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001638- Issue #3739: The unicode-internal encoder now reports the number of characters
1639 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou3a652b12009-03-23 18:52:06 +00001796- Issue #4688: Add a heuristic so that tuples and dicts containing only
1797 untrackable objects are not tracked by the garbage collector. This can
1798 reduce the size of collections and therefore the garbage collection overhead
1799 on long-running programs, depending on their particular use of datatypes.
1800
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001801- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1802 improve its performance. Long divisions and remainder operations
1803 are now between 50% and 150% faster.
1804
Mark Dickinsonbd792642009-03-18 20:06:12 +00001805- Issue #4258: Make it possible to use base 2**30 instead of base
1806 2**15 for the internal representation of integers, for performance
1807 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1808 --enable-big-digits option to configure, which overrides the
1809 default. Add sys.int_info structseq to provide information about
1810 the internal format.
1811
Mark Dickinson081dfee2009-03-18 14:47:41 +00001812- Issue #4474: PyUnicode_FromWideChar now converts characters outside

1814 and sizeof(Py_UNICODE) == 2.
1815
Eric Smith8ec90442009-03-14 12:29:34 +00001816- Issue #5237: Allow auto-numbered fields in str.format(). For

1818
Antoine Pitrou652e7072009-03-13 19:25:20 +00001819- Issue #5392: when a very low recursion limit was set, the interpreter would
1820 abort with a fatal error after the recursion limit was hit twice.
1821
Matthias Klose042f1332009-04-04 14:32:42 +00001822- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1868
Lars Gustäbel42e00912009-03-22 20:34:29 +00001869- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1870 forever on incomplete input. That caused tarfile.open() to hang when used
1871 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

1920 rotating the object pointer by 4 bits to the right.
1921
Mark Dickinson87ec0852009-02-09 17:15:59 +00001922- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1923 it now forces its argument to double before testing for infinity.
1924
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001925- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1926 returns a non-number type.
1927
Benjamin Peterson87618552009-02-08 15:00:52 +00001928- Issue #5182: Removed memoryview.__str__.

1933 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001934
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001935- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001936 were suppressing all exceptions. These include list() and bytearray().
1937
Mark Dickinson1124e712009-01-28 21:25:58 +00001938- Issue #4707: round(x, n) now returns an integer if x is an integer.
1939 Previously it returned a float.
1940
Antoine Pitroub52ec782009-01-25 16:34:23 +00001941- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1942 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1943 evaluation loop is compiled with a new dispatch mechanism which gives
1944 speedups of up to 20%, depending on the system, on various benchmarks.
1945
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001946- Issue #4874: Most builtin decoders now reject unicode input.

1952
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001953- Issue #4838: When a module is deallocated, free the memory backing the
1954 optional module state data.
1955
Mark Dickinson8055afd2009-01-17 10:04:45 +00001956- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1957 type to (void *).
1958
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001959- Issue #4935: The overflow checking code in the expandtabs() method common
1960 to str, bytes and bytearray could be optimized away by the compiler, letting
1961 the interpreter segfault instead of raising an error.
1962
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001963- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1964 __next__ method.
1965
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001966- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1967 function no longer attempt to call the __long__ slot to convert an object
1968 to an integer. Only the __int__ and __trunc__ slots are examined.
1969
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001970- Issue #4893: Use NT threading on CE.

1973
Antoine Pitrouab868312009-01-10 15:40:25 +00001974- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1975 common cases are optimized thanks to a dedicated fast path and a moderate
1976 amount of loop unrolling.
1977
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001978- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1979 collecting the oldest generation) so that allocating lots of objects without
1980 destroying them does not show quadratic performance. Based on a proposal by
1981 Martin von Löwis at
1982 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1983
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001984- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001985 having been closed (for instance, a read() call could return some
1986 previously buffered data). Patch by Dmitry Vasiliev.
1987
Antoine Pitrou05608432009-01-09 18:53:14 +00001988- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1989 flag to work properly. Furthermore, when specifying -u, the text stdout
1990 and stderr streams have line-by-line buffering enabled (the default being
1991 to buffer arbitrary chunks of data).
1992
Raymond Hettinger35631532009-01-09 03:58:09 +00001993- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1994 instead of ints (reducing its size from 4 to 8 times thereby reducing
1995 Python's overall memory).
1996
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001997- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1998 an existing .py counterpart, override the co_filename attributes of all
1999 code objects if the original filename is obsolete (which can happen if the
2000 file has been renamed, moved, or if it is accessed through different paths).
2001 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2002
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002003- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2004 one byte. Also fixes the meaning of len() so that it returns the number of
2005 items, rather than the size in bytes.
2006
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002007- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2008
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002009- Issue #4747: When the terminal does not use utf-8, executing a script with
2010 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2011
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002012- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002013 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002014
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002015- Issue #3680: Reference cycles created through a dict, set or deque iterator
2016 did not get collected.
2017
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002018- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2019 where the tp_hash and tp_dict slots are both NULL.
2020
Georg Brandlccc47b62008-12-28 11:44:14 +00002021- Issue #4759: None is now allowed as the first argument of
2022 bytearray.translate(). It was always allowed for bytes.translate().
2023
Skip Montanaro80072cb2008-12-23 03:51:14 +00002024- Added test case to ensure attempts to read from a file opened for writing
2025 fail.

2030 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2031
Antoine Pitrou621601a2008-12-17 23:18:19 +00002032- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2033 print elapsed times, not only when some objects are uncollectable /
2034 unreachable. Original patch by Neil Schemenauer.
2035
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002036- Issue #3439: Add a bit_length method to int.
2037
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002038- Issue #2173: When getting device encoding, check that return value of
2039 nl_langinfo is not the empty string. This was causing silent build
2040 failures on OS X.
2041
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002042- Issue #4597: Fixed several opcodes that weren't always propagating
2043 exceptions.
2044
2045- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002046 context manager returns a value that cannot be converted to a bool.
2047
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002048- Issue #4445: Replace "sizeof(PyBytesObject)" with
2049 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2050 bytes instances. On a typical machine this saves 3 bytes of memory
2051 (on average) per allocation of a bytes instance.
2052
Christian Heimesa872de52008-12-05 08:26:55 +00002053- Issue #4533: File read operation was dreadfully slow due to a slowly
2054 growing read buffer. Fixed by using the same growth rate algorithm as
2055 Python 2.x.
2056
Antoine Pitrou5504e892008-12-06 21:27:53 +00002057- Issue #4509: Various issues surrounding resize of bytearray objects to
2058 which there are buffer exports (e.g. memoryview instances).
2059
Georg Brandlf9734072008-12-07 15:30:06 +00002060- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2061 method on file objects with closefd=False. The file descriptor is still
2062 kept open but the file object behaves like a closed file. The ``FileIO``
2063 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002064
Antoine Pitroubc420402008-12-07 20:14:49 +00002065- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2066 larger than 1.

2073 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2074 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2075 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou31f30b12009-01-02 17:34:35 +00002656- Issue #4738: Each zlib object now has a separate lock, allowing to compress
2657 or decompress several streams at once on multi-CPU systems. Also, the GIL
2658 is now released when computing the CRC of a large buffer. Patch by ebfe.
2659
Georg Brandlb1441c72009-01-03 22:33:39 +00002660- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00002667- Issue #4583: array.array would not always prohibit resizing when a buffer
2668 has been exported, resulting in an interpreter crash when accessing the
2669 buffer.

Antoine Pitrou88909542009-06-29 13:54:42 +00002677- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2678 regression tests in parallel, shortening the total runtime.
2679
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002680- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2681 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2682 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2683 skip the tests if DISPLAY is defined but can't be used.
2684
R. David Murraya21e4ca2009-03-31 23:16:50 +00002685- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002686 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002687 from test support, which does the conversion.
2688
Guilherme Polo9de29af2009-01-28 20:40:48 +00002689- Issue #5083: New 'gui' resource for regrtest.
