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.

344
Sean Reifscheider13daf122010-04-23 09:29:52 +0000345- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
346 the string "python" as the *ident*. openlog() arguments are all optional
347 and keywords.
348
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000349- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
350 a non-infinite timeout. Also make that method friendlier with applications
351 wanting to continue using the socket in clear-text mode, by disabling
352 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
353
Antoine Pitrou7062db82010-04-22 13:30:10 +0000354- Issue #8496: make mailcap.lookup() always return a list, rather than an
355 iterator. Patch by Gregory Nofi.

Victor Stinner35466c52010-04-22 11:23:23 +0000357- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
358 collation name contains a surrogate character.

Antoine Pitroufec12ff2010-04-21 19:46:23 +0000360- Issue #8484: Load all ciphers and digest algorithms when initializing
361 the _ssl extension, such that verification of some SSL certificates
362 doesn't fail because of an "unknown algorithm".
363
Tarek Ziadéfb437512010-04-20 08:57:33 +0000364- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.

402
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000403- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
404 module now takes an optional timeout argument in seconds. Timeout support
405 relies on the system threading library, so as to avoid a semi-busy wait
406 loop.
407
Victor Stinner485fb562010-04-13 11:07:24 +0000408- Issue #8383: pickle and pickletools use surrogatepass error handler when

410 Python 2.x and 3.0
411
R. David Murrayb2416e52010-04-12 16:58:02 +0000412- Issue #7585: difflib context and unified diffs now place a tab between
413 filename and date, conforming to the 'standards' they were originally
414 designed to follow. This improves compatibility with patch tools.
415
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000416- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
417 character sets will now consistently use a Content-Transfer-Encoding of
418 7bit rather than sometimes being marked as 8bit.
419
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000420- Issue #8375: test_distutils now checks if the temporary directory are still
421 present before it cleans them.

427 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
428 and `ssl.OPENSSL_VERSION_NUMBER`.
429
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000430- Add functools.total_ordering() and functools.cmp_to_key().
431
Mark Dickinson089b00c2010-04-03 15:51:03 +0000432- Issue #8257: The Decimal construct now accepts a float instance
433 directly, converting that float to a Decimal of equal value:
434
435 >>> Decimal(1.1)
436 Decimal('1.100000000000000088817841970012523233890533447265625')
437
Mark Dickinson98127c32010-04-03 11:18:52 +0000438- Issue #8294: The Fraction constructor now accepts Decimal and float
439 instances directly.
440
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000441- Issue #7279: Comparisons involving a Decimal signaling NaN now
442 signal InvalidOperation instead of returning False. (Comparisons
443 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
444 are now hashable; Decimal signaling NaNs remain unhashable.
445
446- Issue #2531: Comparison operations between floats and Decimal
447 instances now return a result based on the numeric values of the
448 operands; previously they returned an arbitrary result based on
449 the relative ordering of id(float) and id(Decimal).
450
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000451- Added a subtract() method to collections.Counter().
452
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000453- Issue #8233: When run as a script, py_compile.py optionally takes a single
454 argument `-` which tells it to read files to compile from stdin. Each line
455 is read on demand and the named file is compiled immediately. (Original
456 patch by Piotr Ożarowski).
457
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000458- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
459 form feed (0x0C) are now considered linebreaks, as specified in Unicode
460 Standard Annex #14. See issue #7643.
461 http://www.unicode.org/reports/tr14/
462
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000463- Comparisons using one of <, <=, >, >= between a complex instance and
464 a Fractions instance now raise TypeError instead of returning
465 True/False. This makes Fraction <=> complex comparisons consistent with
466 int <=> complex, float <=> complex, and complex <=> complex comparisons.
467
Antoine Pitrou39b35432010-03-23 00:25:54 +0000468- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
469 some methods (such as oss_mixer_device.fileno()) were not available.
470 Initial patch by Bertrand Janin.
471
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000472- Issue #8205: Remove the "Modules" directory from sys.path when Python is
473 running from the build directory (POSIX only).
474
Antoine Pitrou910bd512010-03-22 20:11:09 +0000475- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
476 didn't support chflags() (for example ZFS under FreeBSD). The error is
477 now silenced.
478
R. David Murrayca2edce2010-03-22 17:48:48 +0000479- Issue #7860: platform.uname now reports the correct 'machine' type
480 when Python is running in WOW64 mode on 64 bit Windows.
481
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000482- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
483 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
484 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000485
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000486- Issue #4282: Fix the main function of the profile module for a non-ASCII
487 script, open the file in binary mode and not in text mode with the default
488 (utf8) encoding.

495
Benjamin Peterson689a5582010-03-18 22:29:52 +0000496- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
497 detected.
498
Martin v. Löwis4b003072010-03-16 13:19:21 +0000499- Issue #6716/2: Backslash-replace error output in compilall.

Matthias Klosea6d9abf2010-03-16 10:51:28 +0000501- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
502 with Tcl/Tk-8.5.
503
Matthias Klosec33b9022010-03-16 00:36:26 +0000504- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000506- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
507 the locale.
508
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000509- The internals of the subprocess module on POSIX systems have been replaced
510 by an extension module (_posixsubprocess) so that the fork()+exec() can be
511 done safely without the possibility of deadlock in multithreaded applications.
512
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000513- subprocess.Popen now has restore_signals and start_new_session features.
514 The default of restore_signals=True is a new behavior compared to earlier
515 Python versions. This means that signals such as SIGPIPE are not ignored
516 by default in subprocesses launched by Python (Issue #1652).
517
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000518- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
519 cElementTree module is updated too.

528 the replacement were all bytes. Patch by Antoine Pitrou.
529
Gerhard Häringf9cee222010-03-05 15:20:03 +0000530- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
531 bugs and allows loading SQLite extensions from shared libraries.

Victor Stinnercee3ae82010-03-04 00:29:24 +0000536- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
537 reset also the pointer to the current pointer context.

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000547- Issue #691291: codecs.open() should not convert end of lines on reading and
548 writing.
549

Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000563- Issue #6666: fix bug in trace.py that applied the list of directories
564 to be ignored only to the first file. Noted by Bogdan Opanchuk.
565
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000566- Issue #7597: curses.use_env() can now be called before initscr().
567 Noted by Kan-Ru Chen.
568
Ezio Melotti19e4acf2010-02-22 15:59:01 +0000569- Issue #7310: fix the __repr__ of os.environ to show the environment variables.

573
Brett Cannonef7d6722010-02-19 16:04:36 +0000574- Issue #7361: Importlib was not properly checking the number of bytes in
575 bytecode file when it was less then 8 bytes.
576
Mark Dickinson84230a12010-02-18 14:49:50 +0000577- Issue #7633: In the decimal module, Context class methods (with the
578 exception of canonical and is_canonical) now accept instances of int
579 and long wherever a Decimal instance is accepted, and implicitly
580 convert that argument to Decimal. Previously only some arguments
581 were converted.
582
R. David Murray1f449142010-02-11 00:15:05 +0000583- Issue #7835: shelve should no longer produce mysterious warnings during
584 interpreter shutdown.
585
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000586- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
587 in XML processing instructions and comments. These raw characters are
588 allowed by the XML specification, and are necessary when outputting e.g.
589 PHP code in a processing instruction. Patch by Neil Muller.
590
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000591- Issue #6233: ElementTree failed converting unicode characters to XML

601 type is specified. Patch by Brian Curtin.
602
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000603- Issue #6939: Fix file I/O objects in the `io` module to keep the original
604 file position when calling `truncate()`. It would previously change the
605 file position to the given argument, which goes against the tradition of
606 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
607
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000608- Issue #7610: Reworked implementation of the internal
609 :class:`zipfile.ZipExtFile` class used to represent files stored inside
610 an archive. The new implementation is significantly faster and can
611 be wrapped in a :class:`io.BufferedReader` object for more speedups.
612 It also solves an issue where interleaved calls to `read()` and
613 `readline()` give wrong results. Patch by Nir Aides.
614
Jesse Noller1f0b6582010-01-27 03:36:01 +0000615- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
616 allowing for a maximum number of tasks within the pool to be completed by
617 the worker before that worker is terminated, and a new one created to
618 replace it.
619

R. David Murrayba311052009-12-04 00:09:14 +00001202- Issue #7431: use TESTFN in test_linecache instead of trying to create a

1204 user running the tests.
1205
R. David Murray35768ad2009-11-15 00:23:21 +00001206- Issue #7324: add a sanity check to regrtest argument parsing to

1211
Antoine Pitrou060cee22009-11-13 16:29:04 +00001212- Issue #6551: test_zipimport could import and then destroy some modules of

1214 the road because the internally cached encoders and decoders would point
1215 to empty global variables.
1216
Antoine Pitrou941ee882009-11-11 20:59:38 +00001217- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1228 calling methods on the object.
1229
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001230- Issue #7222: Make thread "reaping" more reliable so that reference
1231 leak-chasing test runs give sensible results. The previous method of
1232 reaping threads could return successfully while some Thread objects were
1233 still referenced. This also introduces a new private function:
1234 :func:`_thread._count()`.
1235
R. David Murray27144602009-10-19 15:26:16 +00001236- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1237 longer runs the risk of causing the worker thread to fail.
1238
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001239- Issue #7055: test___all__ now greedily detects all modules which have an
1240 __all__ attribute, rather than using a hardcoded and incomplete list.
1241
R. David Murray0bc11ae2009-10-18 22:18:17 +00001242- Issue #7058: Added save/restore for things like sys.argv and cwd to

1244 and a new section in the summary report at the end.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001519
1520Core and Builtins
1521-----------------
1522
Mark Dickinson865e01a2009-05-07 16:37:01 +00001523- Issue #5914: Add new C API function PyOS_string_to_double, and
1524 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1525
Eric Smith741191f2009-05-06 13:08:15 +00001526- Issue #3382: float.__format__, complex.__format__, and %-formatting
1527 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1528 affects nan -> NAN and inf -> INF.
1529
Mark Hammond5a607a32009-05-06 08:04:54 +00001530- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1531 in all operations, including splitdrive, split, etc. splitunc() now issues
1532 a PendingDeprecation warning.
1533
Eric Smith63376222009-05-05 14:04:18 +00001534- Issue #5920: For float.__format__, change the behavior with the
1535 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1536 to be like 'g' but with at least one decimal point and with a
1537 default precision of 12. Previously, the behavior the same but with
1538 a default precision of 6. This more closely matches str(), and
1539 reduces surprises when adding alignment flags to the empty
1540 presentation type. This also affects the new complex.__format__ in
1541 the same way.
1542
Martin v. Löwis011e8422009-05-05 04:43:17 +00001543- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1544
R. David Murrayb18500d2009-05-04 22:59:07 +00001545- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1546 shadowed by classtype's, even if it was None. property now
1547 inserts the __doc__ into the subclass instance __dict__.
1548
Antoine Pitrou244651a2009-05-04 18:56:13 +00001549- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1550 sequences. Patch by Nick Barnes and Victor Stinner.
1551
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001552- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001553
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001554- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1555 received a new method, detach(). detach() disconnects the underlying stream
1556 from the buffer or text IO and returns it.
1557
Mark Dickinson33841c32009-05-01 15:37:04 +00001558- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1559 floats with absolute value over 1e50. Also remove length
1560 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1561 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001562
Eric Smith741191f2009-05-06 13:08:15 +00001563- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001564 format(complex(1, 2./3), '.5') now produces a sensible result.
1565
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001566- Issue #5864: Fix empty format code formatting for floats so that it
1567 never gives more than the requested number of significant digits.
1568
Eric Smith6dc46f52009-04-27 20:39:49 +00001569- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1570 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1571
Eric Smithcc32a112009-04-26 21:35:14 +00001572- Issue #5835: Deprecate PyOS_ascii_formatd.
1573
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001574- Issue #4971: Fix titlecase for characters that are their own
1575 titlecase, but not their own uppercase.
1576
Benjamin Peterson193152c2009-04-25 01:08:45 +00001577- Issue #5283: Setting __class__ in __del__ caused a segfault.
1578
Mark Dickinsonad476da2009-04-23 19:14:16 +00001579- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1580 z involves nans, infs or negative zeros.
1581
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001582- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001583
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001584- Issue #1869 (and many duplicates): make round(x, n) correctly
1585 rounded for a float x, by using the decimal <-> binary conversions
1586 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1587 consistently agrees with format(x, '.2f').
1588
Benjamin Petersonae937c02009-04-18 20:54:08 +00001589- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1590 some builtin types.
1591
Eric Smith0923d1d2009-04-16 20:16:10 +00001592- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1593
Eric Smith35e84722009-04-16 20:21:28 +00001594- Issue #5515: str.format() type 'n' combined with commas and leading
1595 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001596
1597- Implement PEP 378, Format Specifier for Thousands Separator, for
1598 floats.
1599
Mark Dickinson3370cce2009-04-17 22:40:53 +00001600- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001601 1e11, not 1e12. This avoids printing 13 significant digits in
1602 situations where only 12 of them are correct. Example problem
1603 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1604 long time.)
1605
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001606- Issue #1580: On most platforms, use a 'short' float repr: for a
1607 finite float x, repr(x) now outputs a string based on the shortest
1608 sequence of decimal digits that rounds to x. Previous behaviour was
1609 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001610 Another minor difference is that the new repr switches to
1611 exponential notation at 1e16 instead of the previous 1e17; this
1612 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001613
1614 There's a new sys attribute sys.float_repr_style, which takes
1615 the value 'short' to indicate that we're using short float repr,
1616 and 'legacy' if the short float repr isn't available for one
1617 reason or another.
1618
1619 The float repr change involves incorporating David Gay's 'perfect
1620 rounding' code into the Python core (it's in Python/dtoa.c). As a
1621 secondary consequence, all string-to-float and float-to-string
1622 conversions (including all float formatting operations) will be
1623 correctly rounded on these platforms.
1624
1625 See issue 1580 discussions for details of platforms for which
1626 this change does not apply.
1627
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001628- Issue #5759: float() didn't call __float__ on str subclasses.
1629
Georg Brandlabc38772009-04-12 15:51:51 +00001630- The string.maketrans() function is deprecated; there is a new static method
1631 maketrans() on the bytes and bytearray classes. This removes confusion about
1632 the types string.maketrans() is supposed to work with, and mirrors the
1633 methods available on the str class.
1634
R. David Murraydc6da8a2009-04-09 22:16:43 +00001635- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1636 its clarity and its speed.
1637
Matthias Klose091c7b12009-04-07 13:24:27 +00001638- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1639 to avoid compiler warnings.
1640
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001641- Issue #3739: The unicode-internal encoder now reports the number of characters
1642 consumed like any other encoder (instead of the number of bytes).

1797 the end sys.path, for compatibility with the system install of Python.
1798
Antoine Pitrou3a652b12009-03-23 18:52:06 +00001799- Issue #4688: Add a heuristic so that tuples and dicts containing only
1800 untrackable objects are not tracked by the garbage collector. This can
1801 reduce the size of collections and therefore the garbage collection overhead
1802 on long-running programs, depending on their particular use of datatypes.
1803
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00001804- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
1805 improve its performance. Long divisions and remainder operations
1806 are now between 50% and 150% faster.
1807
Mark Dickinsonbd792642009-03-18 20:06:12 +00001808- Issue #4258: Make it possible to use base 2**30 instead of base
1809 2**15 for the internal representation of integers, for performance
1810 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
1811 --enable-big-digits option to configure, which overrides the
1812 default. Add sys.int_info structseq to provide information about
1813 the internal format.
1814
Mark Dickinson081dfee2009-03-18 14:47:41 +00001815- Issue #4474: PyUnicode_FromWideChar now converts characters outside
1816 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
1817 and sizeof(Py_UNICODE) == 2.
1818
Eric Smith8ec90442009-03-14 12:29:34 +00001819- Issue #5237: Allow auto-numbered fields in str.format(). For
1820 example: '{} {}'.format(1, 2) == '1 2'.
1821
Antoine Pitrou652e7072009-03-13 19:25:20 +00001822- Issue #5392: when a very low recursion limit was set, the interpreter would
1823 abort with a fatal error after the recursion limit was hit twice.
1824
Matthias Klose042f1332009-04-04 14:32:42 +00001825- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

1871
Lars Gustäbel42e00912009-03-22 20:34:29 +00001872- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1873 forever on incomplete input. That caused tarfile.open() to hang when used
1874 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinson87ec0852009-02-09 17:15:59 +00001925- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
1926 it now forces its argument to double before testing for infinity.
1927
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00001928- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
1929 returns a non-number type.
1930
Benjamin Peterson87618552009-02-08 15:00:52 +00001931- Issue #5182: Removed memoryview.__str__.

1936 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00001937
Georg Brandl1cdd83c2009-04-05 20:24:29 +00001938- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00001939 were suppressing all exceptions. These include list() and bytearray().
1940
Mark Dickinson1124e712009-01-28 21:25:58 +00001941- Issue #4707: round(x, n) now returns an integer if x is an integer.
1942 Previously it returned a float.
1943
Antoine Pitroub52ec782009-01-25 16:34:23 +00001944- Issue #4753: By enabling a configure option named '--with-computed-gotos'
1945 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
1946 evaluation loop is compiled with a new dispatch mechanism which gives
1947 speedups of up to 20%, depending on the system, on various benchmarks.
1948
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00001949- Issue #4874: Most builtin decoders now reject unicode input.

1955
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00001956- Issue #4838: When a module is deallocated, free the memory backing the
1957 optional module state data.
1958
Mark Dickinson8055afd2009-01-17 10:04:45 +00001959- Issue #4910: Rename nb_long slot to nb_reserved, and change its
1960 type to (void *).
1961
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00001962- Issue #4935: The overflow checking code in the expandtabs() method common
1963 to str, bytes and bytearray could be optimized away by the compiler, letting
1964 the interpreter segfault instead of raising an error.
1965
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00001966- Issue #3720: Fix a crash when an iterator modifies its class and removes its
1967 __next__ method.
1968
Mark Dickinsone5e298f2009-01-12 20:49:19 +00001969- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
1970 function no longer attempt to call the __long__ slot to convert an object
1971 to an integer. Only the __int__ and __trunc__ slots are examined.
1972
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00001973- Issue #4893: Use NT threading on CE.
1974

1976
Antoine Pitrouab868312009-01-10 15:40:25 +00001977- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
1978 common cases are optimized thanks to a dedicated fast path and a moderate
1979 amount of loop unrolling.
1980
Antoine Pitrou14b78f52009-01-09 22:27:08 +00001981- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
1982 collecting the oldest generation) so that allocating lots of objects without
1983 destroying them does not show quadratic performance. Based on a proposal by
1984 Martin von Löwis at
1985 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
1986
Vinay Sajip6268cbc2009-01-21 00:19:28 +00001987- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00001988 having been closed (for instance, a read() call could return some
1989 previously buffered data). Patch by Dmitry Vasiliev.
1990
Antoine Pitrou05608432009-01-09 18:53:14 +00001991- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
1992 flag to work properly. Furthermore, when specifying -u, the text stdout
1993 and stderr streams have line-by-line buffering enabled (the default being
1994 to buffer arbitrary chunks of data).
1995
Raymond Hettinger35631532009-01-09 03:58:09 +00001996- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
1997 instead of ints (reducing its size from 4 to 8 times thereby reducing
1998 Python's overall memory).
1999
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002000- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2001 an existing .py counterpart, override the co_filename attributes of all
2002 code objects if the original filename is obsolete (which can happen if the
2003 file has been renamed, moved, or if it is accessed through different paths).
2004 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2005
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002006- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2007 one byte. Also fixes the meaning of len() so that it returns the number of
2008 items, rather than the size in bytes.
2009
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002010- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2011
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002012- Issue #4747: When the terminal does not use utf-8, executing a script with
2013 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2014
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002015- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002016 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002017
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002018- Issue #3680: Reference cycles created through a dict, set or deque iterator
2019 did not get collected.
2020
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002021- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2022 where the tp_hash and tp_dict slots are both NULL.
2023
Georg Brandlccc47b62008-12-28 11:44:14 +00002024- Issue #4759: None is now allowed as the first argument of
2025 bytearray.translate(). It was always allowed for bytes.translate().
2026
Skip Montanaro80072cb2008-12-23 03:51:14 +00002027- Added test case to ensure attempts to read from a file opened for writing
2028 fail.

2033 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2034
Antoine Pitrou621601a2008-12-17 23:18:19 +00002035- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2036 print elapsed times, not only when some objects are uncollectable /
2037 unreachable. Original patch by Neil Schemenauer.
2038
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002039- Issue #3439: Add a bit_length method to int.
2040
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002041- Issue #2173: When getting device encoding, check that return value of
2042 nl_langinfo is not the empty string. This was causing silent build
2043 failures on OS X.
2044
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002045- Issue #4597: Fixed several opcodes that weren't always propagating
2046 exceptions.
2047
2048- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002049 context manager returns a value that cannot be converted to a bool.
2050
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002051- Issue #4445: Replace "sizeof(PyBytesObject)" with
2052 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2053 bytes instances. On a typical machine this saves 3 bytes of memory
2054 (on average) per allocation of a bytes instance.
2055
Christian Heimesa872de52008-12-05 08:26:55 +00002056- Issue #4533: File read operation was dreadfully slow due to a slowly
2057 growing read buffer. Fixed by using the same growth rate algorithm as
2058 Python 2.x.
2059
Antoine Pitrou5504e892008-12-06 21:27:53 +00002060- Issue #4509: Various issues surrounding resize of bytearray objects to
2061 which there are buffer exports (e.g. memoryview instances).
2062
Georg Brandlf9734072008-12-07 15:30:06 +00002063- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2064 method on file objects with closefd=False. The file descriptor is still
2065 kept open but the file object behaves like a closed file. The ``FileIO``
2066 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002067
Antoine Pitroubc420402008-12-07 20:14:49 +00002068- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2069 larger than 1.

2074
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002075- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2076 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2077 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Antoine Pitrou31f30b12009-01-02 17:34:35 +00002659- Issue #4738: Each zlib object now has a separate lock, allowing to compress
2660 or decompress several streams at once on multi-CPU systems. Also, the GIL
2661 is now released when computing the CRC of a large buffer. Patch by ebfe.

Antoine Pitrou88909542009-06-29 13:54:42 +00002680- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2681 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002683- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2684 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2685 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2686 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002688- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002689 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002690 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002692- Issue #5083: New 'gui' resource for regrtest.
