20 benefit compared to the dynamic memory allocation fallback. Patch by
21 Charles-François Natali.
22
Benjamin Peterson8380dd52010-04-16 22:51:37 +000023- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is

53 NotImplemented rather than raising a TypeError when comparing with an
54 incompatible type; this allows user-defined classes to implement their own
55 comparisons with complex.
56
Victor Stinner52f6dd72010-03-12 14:45:56 +000057- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt

92
Mark Dickinsonbc099642010-01-29 17:27:24 +000093- Issue #7788: Fix an interpreter crash produced by deleting a list
94 slice with very large step value.
95
Eric Smithf7bb5782010-01-27 00:44:57 +000096- Issue #7766: Change sys.getwindowsversion() return value to a named
97 tuple and add the additional members returned in an OSVERSIONINFOEX

100
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000101- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
102 could crash in many places because of the PyByteArray_AS_STRING() macro
103 returning NULL. The macro now returns a statically allocated empty
104 string instead.
105
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000106- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
107 where the right hand operand is a set of constants, by turning the set into
108 a frozenset and pre-building it as a constant. The comparison operation
109 is made against the constant instead of building a new set each time it is
110 executed (a similar optimization already existed which turned a list of
111 constants into a pre-built tuple). Patch and additional tests by Dave
112 Malcolm.
113
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000114- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

119 alpha 2, including: (1) a serious 'wrong output' bug that could
120 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
121 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000122 strings corresponding to subnormal values, (3) a memory leak for
123 some values large enough to cause overflow, and (4) a number of
124 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000125
Benjamin Petersonaea44282010-01-04 01:10:28 +0000126- The __complex__ method is now looked up on the class of instances to make it

136 negative zero) in ** operator. The behaviour now conforms to that
137 described in C99 Annex F.
138
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000139- Issue #1811: improve accuracy and cross-platform consistency for
140 true division of integers: the result of a/b is now correctly
141 rounded for ints a and b (at least on IEEE 754 platforms), and in
142 particular does not depend on the internal representation of an int.
143
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000144- Issue #6834: replace the implementation for the 'python' and 'pythonw'
145 executables on OSX.
146
147 These executables now work properly with the arch(1) command:
148 ``arch -ppc python`` will start a universal binary version of python
149 in PPC mode (unlike previous releases).
150
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000151- Issue #7466: segmentation fault when the garbage collector is called

166 implement the relevant rich comparison methods.
167
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000168- Issue #7298: fixes for range and reversed(range(...)). Iteration
169 over range(a, b, c) incorrectly gave an empty iterator when a, b and
170 c fit in C long but the length of the range did not. Also fix
171 several cases where reversed(range(a, b, c)) gave wrong results, and

316 object at a specified file, function, and line number.
317
318- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
319 ``const char *`` as the string is stored beyond the call.
320
Benjamin Peterson05159c42009-12-03 03:01:27 +0000321- Issue #2422: When compiled with the ``--with-valgrind`` option, the
322 pymalloc allocator will be automatically disabled when running under
323 Valgrind. This gives improved memory leak detection when running
324 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou7062db82010-04-22 13:30:10 +0000329- Issue #8496: make mailcap.lookup() always return a list, rather than an
330 iterator. Patch by Gregory Nofi.
331
Victor Stinner35466c52010-04-22 11:23:23 +0000332- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
333 collation name contains a surrogate character.
334
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000335- Issue #8484: Load all ciphers and digest algorithms when initializing
336 the _ssl extension, such that verification of some SSL certificates
337 doesn't fail because of an "unknown algorithm".
338
Tarek Ziadéfb437512010-04-20 08:57:33 +0000339- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
340
Tarek Ziadé5340db32010-04-19 22:30:51 +0000341- Issue #1540112: Now allowing the choice of a copy function in
342 shutil.copytree.
343
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000344- Issue #4814: timeout parameter is now applied also for connections resulting
345 from PORT/EPRT commands.
346
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000347- Issue #8463: added missing reference to bztar in shutil's documentation.
348
Ronald Oussoren84151202010-04-18 20:46:11 +0000349- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
350 (as long as the user didn't specify 'automatic proxy configuration').

Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000352- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
353 code as stated in RFC-959 at chapter 5.4.
354
Victor Stinner738446f02010-04-18 00:00:44 +0000355- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
356 surrogates.
357
Antoine Pitrou0454af92010-04-17 23:51:58 +0000358- Issue #850728: Add a *timeout* parameter to the `acquire()` method of

377
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000378- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
379 module now takes an optional timeout argument in seconds. Timeout support
380 relies on the system threading library, so as to avoid a semi-busy wait
381 loop.
382
Victor Stinner485fb562010-04-13 11:07:24 +0000383- Issue #8383: pickle and pickletools use surrogatepass error handler when
384 encoding unicode as utf8 to support lone surrogates and stay compatible with
385 Python 2.x and 3.0
386
R. David Murrayb2416e52010-04-12 16:58:02 +0000387- Issue #7585: difflib context and unified diffs now place a tab between
388 filename and date, conforming to the 'standards' they were originally
389 designed to follow. This improves compatibility with patch tools.
390
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000391- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
392 character sets will now consistently use a Content-Transfer-Encoding of
393 7bit rather than sometimes being marked as 8bit.
394
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000395- Issue #8375: test_distutils now checks if the temporary directory are still
396 present before it cleans them.

402 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
403 and `ssl.OPENSSL_VERSION_NUMBER`.
404
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000405- Add functools.total_ordering() and functools.cmp_to_key().
406
Mark Dickinson089b00c2010-04-03 15:51:03 +0000407- Issue #8257: The Decimal construct now accepts a float instance
408 directly, converting that float to a Decimal of equal value:
409
410 >>> Decimal(1.1)
411 Decimal('1.100000000000000088817841970012523233890533447265625')
412
Mark Dickinson98127c32010-04-03 11:18:52 +0000413- Issue #8294: The Fraction constructor now accepts Decimal and float
414 instances directly.
415
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000416- Issue #7279: Comparisons involving a Decimal signaling NaN now
417 signal InvalidOperation instead of returning False. (Comparisons
418 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
419 are now hashable; Decimal signaling NaNs remain unhashable.
420
421- Issue #2531: Comparison operations between floats and Decimal
422 instances now return a result based on the numeric values of the
423 operands; previously they returned an arbitrary result based on
424 the relative ordering of id(float) and id(Decimal).
425
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000426- Added a subtract() method to collections.Counter().
427
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000428- Issue #8233: When run as a script, py_compile.py optionally takes a single
429 argument `-` which tells it to read files to compile from stdin. Each line
430 is read on demand and the named file is compiled immediately. (Original
431 patch by Piotr Ożarowski).
432
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000433- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
434 form feed (0x0C) are now considered linebreaks, as specified in Unicode
435 Standard Annex #14. See issue #7643.
436 http://www.unicode.org/reports/tr14/
437
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000438- Comparisons using one of <, <=, >, >= between a complex instance and
439 a Fractions instance now raise TypeError instead of returning
440 True/False. This makes Fraction <=> complex comparisons consistent with
441 int <=> complex, float <=> complex, and complex <=> complex comparisons.
442
Antoine Pitrou39b35432010-03-23 00:25:54 +0000443- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
444 some methods (such as oss_mixer_device.fileno()) were not available.
445 Initial patch by Bertrand Janin.
446
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000447- Issue #8205: Remove the "Modules" directory from sys.path when Python is
448 running from the build directory (POSIX only).
449
Antoine Pitrou910bd512010-03-22 20:11:09 +0000450- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
451 didn't support chflags() (for example ZFS under FreeBSD). The error is
452 now silenced.
453
R. David Murrayca2edce2010-03-22 17:48:48 +0000454- Issue #7860: platform.uname now reports the correct 'machine' type
455 when Python is running in WOW64 mode on 64 bit Windows.
456
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000457- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
458 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
459 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000460
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000461- Issue #4282: Fix the main function of the profile module for a non-ASCII
462 script, open the file in binary mode and not in text mode with the default
463 (utf8) encoding.
464
Florent Xicluna54467e02010-03-21 12:29:50 +0000465- Issue #8179: Fix macpath.realpath() on a non-existing path.
466

468
Benjamin Peterson00888932010-03-18 22:37:38 +0000469- Issue #8168: py_compile now handles files with utf-8 BOMS.
470
Benjamin Peterson689a5582010-03-18 22:29:52 +0000471- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
472 detected.
473
Martin v. Löwis4b003072010-03-16 13:19:21 +0000474- Issue #6716/2: Backslash-replace error output in compilall.
475
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000476- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
477 with Tcl/Tk-8.5.
478
Matthias Klosec33b9022010-03-16 00:36:26 +0000479- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000481- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
482 the locale.
483
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000484- The internals of the subprocess module on POSIX systems have been replaced
485 by an extension module (_posixsubprocess) so that the fork()+exec() can be
486 done safely without the possibility of deadlock in multithreaded applications.
487
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000488- subprocess.Popen now has restore_signals and start_new_session features.
489 The default of restore_signals=True is a new behavior compared to earlier
490 Python versions. This means that signals such as SIGPIPE are not ignored
491 by default in subprocesses launched by Python (Issue #1652).
492
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000493- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
494 cElementTree module is updated too.
495

503 the replacement were all bytes. Patch by Antoine Pitrou.
504
Gerhard Häringf9cee222010-03-05 15:20:03 +0000505- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
506 bugs and allows loading SQLite extensions from shared libraries.
507
Ezio Melottida227042010-03-14 11:51:00 +0000508- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Victor Stinnercee3ae82010-03-04 00:29:24 +0000511- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
512 reset also the pointer to the current pointer context.
513
Lars Gustäbel01385812010-03-03 12:08:54 +0000514- Issue #7232: Add support for the context manager protocol to the TarFile

521
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000522- Issue #691291: codecs.open() should not convert end of lines on reading and
523 writing.
524
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000525- Issue #7869: logging: improved diagnostic for format-time errors.

Thomas Heller5117b0b2010-02-23 20:25:02 +0000533- Issue #7959: ctypes callback functions are now registered correctly
Ezio Melotti8b1458b2010-02-24 16:55:43 +0000534 with the cycle garbage collector.
Thomas Heller5117b0b2010-02-23 20:25:02 +0000535

537
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000538- Issue #6666: fix bug in trace.py that applied the list of directories
539 to be ignored only to the first file. Noted by Bogdan Opanchuk.
540
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000541- Issue #7597: curses.use_env() can now be called before initscr().
542 Noted by Kan-Ru Chen.
543
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000544- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

547 messages parsed by email.Parser.HeaderParser.
548
Brett Cannonef7d6722010-02-19 16:04:36 +0000549- Issue #7361: Importlib was not properly checking the number of bytes in
550 bytecode file when it was less then 8 bytes.
551
Mark Dickinson84230a12010-02-18 14:49:50 +0000552- Issue #7633: In the decimal module, Context class methods (with the
553 exception of canonical and is_canonical) now accept instances of int
554 and long wherever a Decimal instance is accepted, and implicitly
555 convert that argument to Decimal. Previously only some arguments
556 were converted.
557
R. David Murray1f449142010-02-11 00:15:05 +0000558- Issue #7835: shelve should no longer produce mysterious warnings during
559 interpreter shutdown.
560
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000561- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
562 in XML processing instructions and comments. These raw characters are
563 allowed by the XML specification, and are necessary when outputting e.g.
564 PHP code in a processing instruction. Patch by Neil Muller.
565
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000566- Issue #6233: ElementTree failed converting unicode characters to XML

571 specify the compression type.
572
Antoine Pitroub6375f12010-02-04 20:23:24 +0000573- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

576 type is specified. Patch by Brian Curtin.
577
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000578- Issue #6939: Fix file I/O objects in the `io` module to keep the original
579 file position when calling `truncate()`. It would previously change the
580 file position to the given argument, which goes against the tradition of
581 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
582
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000583- Issue #7610: Reworked implementation of the internal
584 :class:`zipfile.ZipExtFile` class used to represent files stored inside
585 an archive. The new implementation is significantly faster and can
586 be wrapped in a :class:`io.BufferedReader` object for more speedups.
587 It also solves an issue where interleaved calls to `read()` and
588 `readline()` give wrong results. Patch by Nir Aides.
589
Jesse Noller1f0b6582010-01-27 03:36:01 +0000590- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
591 allowing for a maximum number of tasks within the pool to be completed by
592 the worker before that worker is terminated, and a new one created to
593 replace it.
594
Benjamin Petersond6326642010-01-27 02:25:58 +0000595- Issue #7792: Registering non-classes to ABCs raised an obscure error.
596
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000597- Issue #7785: Don't accept bytes in FileIO.write().

Ezio Melotti38f00332010-01-25 12:39:47 +0000599- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
600
Benjamin Peterson25001472010-01-25 03:37:42 +0000601- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

752 to execute file paths that refer to source or compiled Python files as well

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

1193
Brett Cannoncfed0292009-11-05 01:26:57 +00001194- Issue #7248 (part 2): Use a unique temporary directory for importlib source
1195 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1196 between concurrent executions on the same system.
1197

1200 calling methods on the object.
1201
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001202- Issue #7222: Make thread "reaping" more reliable so that reference
1203 leak-chasing test runs give sensible results. The previous method of
1204 reaping threads could return successfully while some Thread objects were
1205 still referenced. This also introduces a new private function:
1206 :func:`_thread._count()`.

1213
R. David Murray0bc11ae2009-10-18 22:18:17 +00001214- Issue #7058: Added save/restore for things like sys.argv and cwd to

1493-----------------
1494
Mark Dickinson865e01a2009-05-07 16:37:01 +00001495- Issue #5914: Add new C API function PyOS_string_to_double, and
1496 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1497
Eric Smith741191f2009-05-06 13:08:15 +00001498- Issue #3382: float.__format__, complex.__format__, and %-formatting
1499 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1500 affects nan -> NAN and inf -> INF.
1501
Mark Hammond5a607a32009-05-06 08:04:54 +00001502- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1503 in all operations, including splitdrive, split, etc. splitunc() now issues
1504 a PendingDeprecation warning.
1505
Eric Smith63376222009-05-05 14:04:18 +00001506- Issue #5920: For float.__format__, change the behavior with the
1507 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1508 to be like 'g' but with at least one decimal point and with a
1509 default precision of 12. Previously, the behavior the same but with
1510 a default precision of 6. This more closely matches str(), and
1511 reduces surprises when adding alignment flags to the empty
1512 presentation type. This also affects the new complex.__format__ in
1513 the same way.
1514
Martin v. Löwis011e8422009-05-05 04:43:17 +00001515- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1516
R. David Murrayb18500d2009-05-04 22:59:07 +00001517- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1518 shadowed by classtype's, even if it was None. property now
1519 inserts the __doc__ into the subclass instance __dict__.
1520
Antoine Pitrou244651a2009-05-04 18:56:13 +00001521- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1522 sequences. Patch by Nick Barnes and Victor Stinner.
1523
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001524- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001525
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001526- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1527 received a new method, detach(). detach() disconnects the underlying stream
1528 from the buffer or text IO and returns it.
1529
Mark Dickinson33841c32009-05-01 15:37:04 +00001530- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1531 floats with absolute value over 1e50. Also remove length
1532 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1533 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001534
Eric Smith741191f2009-05-06 13:08:15 +00001535- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001536 format(complex(1, 2./3), '.5') now produces a sensible result.
1537
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001538- Issue #5864: Fix empty format code formatting for floats so that it
1539 never gives more than the requested number of significant digits.
1540
Eric Smith6dc46f52009-04-27 20:39:49 +00001541- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1542 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1543
Eric Smithcc32a112009-04-26 21:35:14 +00001544- Issue #5835: Deprecate PyOS_ascii_formatd.
1545
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001546- Issue #4971: Fix titlecase for characters that are their own
1547 titlecase, but not their own uppercase.
1548
Benjamin Peterson193152c2009-04-25 01:08:45 +00001549- Issue #5283: Setting __class__ in __del__ caused a segfault.
1550
Mark Dickinsonad476da2009-04-23 19:14:16 +00001551- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1552 z involves nans, infs or negative zeros.
1553
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001554- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001555
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001556- Issue #1869 (and many duplicates): make round(x, n) correctly
1557 rounded for a float x, by using the decimal <-> binary conversions
1558 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1559 consistently agrees with format(x, '.2f').
1560
Benjamin Petersonae937c02009-04-18 20:54:08 +00001561- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1562 some builtin types.
1563
Eric Smith0923d1d2009-04-16 20:16:10 +00001564- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1565
Eric Smith35e84722009-04-16 20:21:28 +00001566- Issue #5515: str.format() type 'n' combined with commas and leading
1567 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001568
1569- Implement PEP 378, Format Specifier for Thousands Separator, for
1570 floats.
1571
Mark Dickinson3370cce2009-04-17 22:40:53 +00001572- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001573 1e11, not 1e12. This avoids printing 13 significant digits in
1574 situations where only 12 of them are correct. Example problem
1575 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1576 long time.)
1577
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001578- Issue #1580: On most platforms, use a 'short' float repr: for a
1579 finite float x, repr(x) now outputs a string based on the shortest
1580 sequence of decimal digits that rounds to x. Previous behaviour was
1581 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001582 Another minor difference is that the new repr switches to
1583 exponential notation at 1e16 instead of the previous 1e17; this
1584 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001585
1586 There's a new sys attribute sys.float_repr_style, which takes
1587 the value 'short' to indicate that we're using short float repr,
1588 and 'legacy' if the short float repr isn't available for one
1589 reason or another.
1590
1591 The float repr change involves incorporating David Gay's 'perfect
1592 rounding' code into the Python core (it's in Python/dtoa.c). As a
1593 secondary consequence, all string-to-float and float-to-string
1594 conversions (including all float formatting operations) will be
1595 correctly rounded on these platforms.
1596
1597 See issue 1580 discussions for details of platforms for which
1598 this change does not apply.
1599
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001600- Issue #5759: float() didn't call __float__ on str subclasses.
1601
Georg Brandlabc38772009-04-12 15:51:51 +00001602- The string.maketrans() function is deprecated; there is a new static method
1603 maketrans() on the bytes and bytearray classes. This removes confusion about
1604 the types string.maketrans() is supposed to work with, and mirrors the
1605 methods available on the str class.
1606
R. David Murraydc6da8a2009-04-09 22:16:43 +00001607- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1608 its clarity and its speed.
1609
Matthias Klose091c7b12009-04-07 13:24:27 +00001610- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1611 to avoid compiler warnings.
1612
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001613- Issue #3739: The unicode-internal encoder now reports the number of characters
1614 consumed like any other encoder (instead of the number of bytes).

1629
Vinay Sajipaffbd872009-06-11 10:11:47 +00001630- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1693 results in a handle_expt_event call, not handle_read_event, and POLLERR
1694 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1695 dispatcher now has an 'ignore_log_types' attribute for suppressing
1696 log messages, which is set to 'warning' by default.
1697

Benjamin Peterson8f76b492009-04-03 22:22:42 +00001749- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
1750
Benjamin Peterson7fe98532009-04-02 00:33:55 +00001751- Issue #5499: The 'c' code for argument parsing functions now only accepts a
1752 byte, and the 'C' code only accepts a unicode character.
1753
Georg Brandl406b3d82009-04-11 21:24:37 +00001754- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

1760 insufficient checks in accessors of Exception.__context__.
1761
Guido van Rossum0ad59d42009-03-30 22:01:35 +00001762- Issue #5604: non-ASCII characters in module name passed to
1763 imp.find_module() were converted to UTF-8 while the path is
1764 converted to the default filesystem encoding, causing nonsense.
1765
Benjamin Peterson09832742009-03-26 17:15:46 +00001766- Issue #5126: str.isprintable() returned False for space characters.
1767
Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00001768- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
1769 the end sys.path, for compatibility with the system install of Python.
1770
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001771- Issue #4688: Add a heuristic so that tuples and dicts containing only
1772 untrackable objects are not tracked by the garbage collector. This can
1773 reduce the size of collections and therefore the garbage collection overhead
1774 on long-running programs, depending on their particular use of datatypes.
1775
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001776- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

1781 2**15 for the internal representation of integers, for performance
1782 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1783 --enable-big-digits option to configure, which overrides the
1784 default. Add sys.int_info structseq to provide information about
1785 the internal format.
1786
Mark Dickinson081dfee2009-03-18 14:47:41 +00001787- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1788 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1789 and sizeof(Py_UNICODE) == 2.
1790
Eric Smith8ec90442009-03-14 12:29:34 +00001791- Issue #5237: Allow auto-numbered fields in str.format(). For

Mark Dickinson87ec0852009-02-09 17:15:59 +00001897- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1898 it now forces its argument to double before testing for infinity.
1899
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001900- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001909
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001910- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001911 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00001913- Issue #4707: round(x, n) now returns an integer if x is an integer.
1914 Previously it returned a float.
1915
Antoine Pitroub52ec782009-01-25 16:34:23 +00001916- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1917 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1918 evaluation loop is compiled with a new dispatch mechanism which gives
1919 speedups of up to 20%, depending on the system, on various benchmarks.
1920
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001921- Issue #4874: Most builtin decoders now reject unicode input.

1927
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001928- Issue #4838: When a module is deallocated, free the memory backing the
1929 optional module state data.
1930
Mark Dickinson8055afd2009-01-17 10:04:45 +00001931- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1932 type to (void *).
1933
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001934- Issue #4935: The overflow checking code in the expandtabs() method common
1935 to str, bytes and bytearray could be optimized away by the compiler, letting
1936 the interpreter segfault instead of raising an error.
1937
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001938- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1939 __next__ method.
1940
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001941- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1942 function no longer attempt to call the __long__ slot to convert an object
1943 to an integer. Only the __int__ and __trunc__ slots are examined.
1944
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001945- Issue #4893: Use NT threading on CE.
1946

1948
Antoine Pitrouab868312009-01-10 15:40:25 +00001949- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1950 common cases are optimized thanks to a dedicated fast path and a moderate
1951 amount of loop unrolling.
1952
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001953- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1954 collecting the oldest generation) so that allocating lots of objects without
1955 destroying them does not show quadratic performance. Based on a proposal by
1956 Martin von Löwis at
1957 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1958
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001959- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001960 having been closed (for instance, a read() call could return some
1961 previously buffered data). Patch by Dmitry Vasiliev.
1962
Antoine Pitrou05608432009-01-09 18:53:14 +00001963- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1964 flag to work properly. Furthermore, when specifying -u, the text stdout
1965 and stderr streams have line-by-line buffering enabled (the default being
1966 to buffer arbitrary chunks of data).
1967
Raymond Hettinger35631532009-01-09 03:58:09 +00001968- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1969 instead of ints (reducing its size from 4 to 8 times thereby reducing
1970 Python's overall memory).
1971
Antoine Pitroud35cbf62009-01-06 19:02:24 +00001972- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
1973 an existing .py counterpart, override the co_filename attributes of all
1974 code objects if the original filename is obsolete (which can happen if the
1975 file has been renamed, moved, or if it is accessed through different paths).
1976 Patch by Ziga Seilnacht and Jean-Paul Calderone.
1977
Antoine Pitrouc3b39242009-01-03 16:59:18 +00001978- Issue #4580: Fix slicing of memoryviews when the item size is greater than
1979 one byte. Also fixes the meaning of len() so that it returns the number of
1980 items, rather than the size in bytes.
1981
Martin v. Löwis5c88d812009-01-02 20:47:48 +00001982- Issue #4075: Use OutputDebugStringW in Py_FatalError.
1983
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00001984- Issue #4747: When the terminal does not use utf-8, executing a script with
1985 non-ascii characters in its name could fail with a "SyntaxError: None" error.
1986
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001987- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00001988 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00001989
Antoine Pitrou7ddda782009-01-01 15:35:33 +00001990- Issue #3680: Reference cycles created through a dict, set or deque iterator
1991 did not get collected.
1992
Nick Coghlanf1f2f682008-12-30 07:29:12 +00001993- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
1994 where the tp_hash and tp_dict slots are both NULL.
1995
Georg Brandlccc47b62008-12-28 11:44:14 +00001996- Issue #4759: None is now allowed as the first argument of
1997 bytearray.translate(). It was always allowed for bytes.translate().
1998
Skip Montanaro80072cb2008-12-23 03:51:14 +00001999- Added test case to ensure attempts to read from a file opened for writing
2000 fail.
2001

2006
Antoine Pitrou621601a2008-12-17 23:18:19 +00002007- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2008 print elapsed times, not only when some objects are uncollectable /
2009 unreachable. Original patch by Neil Schemenauer.
2010
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002011- Issue #3439: Add a bit_length method to int.
2012
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002013- Issue #2173: When getting device encoding, check that return value of
2014 nl_langinfo is not the empty string. This was causing silent build
2015 failures on OS X.
2016
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002017- Issue #4597: Fixed several opcodes that weren't always propagating
2018 exceptions.

Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002021 context manager returns a value that cannot be converted to a bool.
2022
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002023- Issue #4445: Replace "sizeof(PyBytesObject)" with
2024 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2025 bytes instances. On a typical machine this saves 3 bytes of memory
2026 (on average) per allocation of a bytes instance.
2027
Christian Heimesa872de52008-12-05 08:26:55 +00002028- Issue #4533: File read operation was dreadfully slow due to a slowly
2029 growing read buffer. Fixed by using the same growth rate algorithm as
2030 Python 2.x.
2031
Antoine Pitrou5504e892008-12-06 21:27:53 +00002032- Issue #4509: Various issues surrounding resize of bytearray objects to
2033 which there are buffer exports (e.g. memoryview instances).
2034
Georg Brandlf9734072008-12-07 15:30:06 +00002035- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2036 method on file objects with closefd=False. The file descriptor is still
2037 kept open but the file object behaves like a closed file. The ``FileIO``
2038 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002039
Antoine Pitroubc420402008-12-07 20:14:49 +00002040- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2048 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2049 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2050 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00002652- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2653 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002655- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2656 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2657 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2658 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002660- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002661 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002662 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002664- Issue #5083: New 'gui' resource for regrtest.
