Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000117- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
118 could crash in many places because of the PyByteArray_AS_STRING() macro
119 returning NULL. The macro now returns a statically allocated empty
120 string instead.
121
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000122- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
123 where the right hand operand is a set of constants, by turning the set into
124 a frozenset and pre-building it as a constant. The comparison operation
125 is made against the constant instead of building a new set each time it is
126 executed (a similar optimization already existed which turned a list of
127 constants into a pre-built tuple). Patch and additional tests by Dave
128 Malcolm.
129
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000130- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

135 alpha 2, including: (1) a serious 'wrong output' bug that could
136 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
137 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000138 strings corresponding to subnormal values, (3) a memory leak for
139 some values large enough to cause overflow, and (4) a number of
140 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000141
Benjamin Petersonaea44282010-01-04 01:10:28 +0000142- The __complex__ method is now looked up on the class of instances to make it

153 described in C99 Annex F.
154
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000155- Issue #1811: improve accuracy and cross-platform consistency for
156 true division of integers: the result of a/b is now correctly
157 rounded for ints a and b (at least on IEEE 754 platforms), and in
158 particular does not depend on the internal representation of an int.
159
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000160- Issue #6834: replace the implementation for the 'python' and 'pythonw'
161 executables on OSX.
162
163 These executables now work properly with the arch(1) command:
164 ``arch -ppc python`` will start a universal binary version of python
165 in PPC mode (unlike previous releases).
166
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000167- Issue #7466: segmentation fault when the garbage collector is called

183
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000184- Issue #7298: fixes for range and reversed(range(...)). Iteration
185 over range(a, b, c) incorrectly gave an empty iterator when a, b and
186 c fit in C long but the length of the range did not. Also fix
187 several cases where reversed(range(a, b, c)) gave wrong results, and
188 fix a refleak for reversed(range(a, b, c)) with large arguments.

Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000320 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
321
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000322- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
323 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
324 should used for accessing the d_type and d_name members of structures
325 using PyDescr_COMMON.
326
327- Issue #6405: Remove duplicate type declarations in descrobject.h.

Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000331- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
332 PyCode_Addr2Line().
333
334- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
335 object at a specified file, function, and line number.
336
337- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
338 ``const char *`` as the string is stored beyond the call.
339
Benjamin Peterson05159c42009-12-03 03:01:27 +0000340- Issue #2422: When compiled with the ``--with-valgrind`` option, the
341 pymalloc allocator will be automatically disabled when running under
342 Valgrind. This gives improved memory leak detection when running
343 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou6be88762010-05-03 16:48:20 +0000348- Issue #7865: The close() method of :mod:`io` objects should not swallow
349 exceptions raised by the implicit flush(). Also ensure that calling
350 close() several times is supported. Patch by Pascal Chambon.
351
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000352- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
353 gc.DEBUG_STATS.

Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000355- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
356 webbrowser.get("safari").
357
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000358- Issue #8464: tarfile no longer creates files with execute permissions set
359 when mode="w|" is used.
360
Antoine Pitroubf043492010-04-29 10:11:46 +0000361- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
362 of the Linux kernel. Patch by Yaniv Aknin.

365
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000366- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
367 It should correctly return an empty response now.
368
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000369- Issue #8546: Reject None given as the buffering argument to _pyio.open.

375 and mappings.
376
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000377- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
378 where the method could block indefinitely if called just before the
379 event loop started running. This also fixes the occasional freezes
380 witnessed in test_httpservers.
381
Antoine Pitrou40f08742010-04-24 22:04:40 +0000382- Issue #8524: When creating an SSL socket, the timeout value of the
383 original socket wasn't retained (instead, a socket with a positive timeout
384 would be turned into a non-blocking SSL socket).
385
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000386- Issue #5103: SSL handshake would ignore the socket timeout and block
387 indefinitely if the other end didn't respond.
388
389- The do_handshake() method of SSL objects now adjusts the blocking mode of
390 the SSL structure if necessary (as other methods already do).
391
Victor Stinner13bb71c2010-04-23 21:41:56 +0000392- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
393 and bytes strings for environment keys and values
394
Victor Stinner4d078042010-04-23 19:28:32 +0000395- Issue #8467: Pure Python implementation of subprocess encodes the error

400
Sean Reifscheider13daf122010-04-23 09:29:52 +0000401- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
402 the string "python" as the *ident*. openlog() arguments are all optional
403 and keywords.
404
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000405- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
406 a non-infinite timeout. Also make that method friendlier with applications
407 wanting to continue using the socket in clear-text mode, by disabling
408 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
409
Antoine Pitrou7062db82010-04-22 13:30:10 +0000410- Issue #8496: make mailcap.lookup() always return a list, rather than an
411 iterator. Patch by Gregory Nofi.
412
Victor Stinner35466c52010-04-22 11:23:23 +0000413- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
414 collation name contains a surrogate character.
415
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000416- Issue #8484: Load all ciphers and digest algorithms when initializing
417 the _ssl extension, such that verification of some SSL certificates
418 doesn't fail because of an "unknown algorithm".
419
Tarek Ziadéfb437512010-04-20 08:57:33 +0000420- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
421
Tarek Ziadé5340db32010-04-19 22:30:51 +0000422- Issue #1540112: Now allowing the choice of a copy function in
423 shutil.copytree.
424
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000425- Issue #4814: timeout parameter is now applied also for connections resulting
426 from PORT/EPRT commands.
427
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000428- Issue #8463: added missing reference to bztar in shutil's documentation.
429
Ronald Oussoren84151202010-04-18 20:46:11 +0000430- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
431 (as long as the user didn't specify 'automatic proxy configuration').
432
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000433- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
434 code as stated in RFC-959 at chapter 5.4.
435
Victor Stinner738446f02010-04-18 00:00:44 +0000436- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
437 surrogates.
438
Antoine Pitrou0454af92010-04-17 23:51:58 +0000439- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000440 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000441
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000442- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
443 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
444
Victor Stinner0e59cc32010-04-16 23:49:32 +0000445- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
446 the current working directory.

452 surrogates.
453
Senthil Kumaranad02d232010-04-16 03:02:13 +0000454- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
455 Locke and Hans Ulrich Niedermann.
456
R. David Murrayd48739f2010-04-14 18:59:18 +0000457- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
458
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000459- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
460 module now takes an optional timeout argument in seconds. Timeout support
461 relies on the system threading library, so as to avoid a semi-busy wait
462 loop.
463
Victor Stinner485fb562010-04-13 11:07:24 +0000464- Issue #8383: pickle and pickletools use surrogatepass error handler when
465 encoding unicode as utf8 to support lone surrogates and stay compatible with
466 Python 2.x and 3.0
467
R. David Murrayb2416e52010-04-12 16:58:02 +0000468- Issue #7585: difflib context and unified diffs now place a tab between
469 filename and date, conforming to the 'standards' they were originally
470 designed to follow. This improves compatibility with patch tools.
471
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000472- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
473 character sets will now consistently use a Content-Transfer-Encoding of
474 7bit rather than sometimes being marked as 8bit.
475
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000476- Issue #8375: test_distutils now checks if the temporary directory are still
477 present before it cleans them.
478
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000479- Issue #8374: Update the internal alias table in the :mod:`locale` module
480 to cover recent locale changes and additions.
481
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000482- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
483 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
484 and `ssl.OPENSSL_VERSION_NUMBER`.
485
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000486- Add functools.total_ordering() and functools.cmp_to_key().
487
Mark Dickinson089b00c2010-04-03 15:51:03 +0000488- Issue #8257: The Decimal construct now accepts a float instance
489 directly, converting that float to a Decimal of equal value:
490
491 >>> Decimal(1.1)
492 Decimal('1.100000000000000088817841970012523233890533447265625')
493
Mark Dickinson98127c32010-04-03 11:18:52 +0000494- Issue #8294: The Fraction constructor now accepts Decimal and float
495 instances directly.
496
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000497- Issue #7279: Comparisons involving a Decimal signaling NaN now
498 signal InvalidOperation instead of returning False. (Comparisons
499 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
500 are now hashable; Decimal signaling NaNs remain unhashable.
501
502- Issue #2531: Comparison operations between floats and Decimal
503 instances now return a result based on the numeric values of the
504 operands; previously they returned an arbitrary result based on
505 the relative ordering of id(float) and id(Decimal).
506
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000507- Added a subtract() method to collections.Counter().
508
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000509- Issue #8233: When run as a script, py_compile.py optionally takes a single
510 argument `-` which tells it to read files to compile from stdin. Each line
511 is read on demand and the named file is compiled immediately. (Original
512 patch by Piotr Ożarowski).
513
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000514- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
515 form feed (0x0C) are now considered linebreaks, as specified in Unicode
516 Standard Annex #14. See issue #7643.
517 http://www.unicode.org/reports/tr14/
518
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000519- Comparisons using one of <, <=, >, >= between a complex instance and
520 a Fractions instance now raise TypeError instead of returning
521 True/False. This makes Fraction <=> complex comparisons consistent with
522 int <=> complex, float <=> complex, and complex <=> complex comparisons.
523
Antoine Pitrou39b35432010-03-23 00:25:54 +0000524- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

526 Initial patch by Bertrand Janin.
527
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000528- Issue #8205: Remove the "Modules" directory from sys.path when Python is
529 running from the build directory (POSIX only).
530
Antoine Pitrou910bd512010-03-22 20:11:09 +0000531- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
532 didn't support chflags() (for example ZFS under FreeBSD). The error is
533 now silenced.
534
R. David Murrayca2edce2010-03-22 17:48:48 +0000535- Issue #7860: platform.uname now reports the correct 'machine' type
536 when Python is running in WOW64 mode on 64 bit Windows.
537
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000538- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
539 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
540 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000541
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000542- Issue #4282: Fix the main function of the profile module for a non-ASCII
543 script, open the file in binary mode and not in text mode with the default
544 (utf8) encoding.
545
Florent Xicluna54467e02010-03-21 12:29:50 +0000546- Issue #8179: Fix macpath.realpath() on a non-existing path.

551
Benjamin Peterson689a5582010-03-18 22:29:52 +0000552- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
553 detected.
554
Martin v. Löwis4b003072010-03-16 13:19:21 +0000555- Issue #6716/2: Backslash-replace error output in compilall.
556
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000557- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
558 with Tcl/Tk-8.5.
559
Matthias Klosec33b9022010-03-16 00:36:26 +0000560- Issue #8140: extend compileall to compile single files. Add -i option.

563 the locale.
564
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000565- The internals of the subprocess module on POSIX systems have been replaced
566 by an extension module (_posixsubprocess) so that the fork()+exec() can be
567 done safely without the possibility of deadlock in multithreaded applications.
568
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000569- subprocess.Popen now has restore_signals and start_new_session features.
570 The default of restore_signals=True is a new behavior compared to earlier
571 Python versions. This means that signals such as SIGPIPE are not ignored
572 by default in subprocesses launched by Python (Issue #1652).
573
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000574- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

584 the replacement were all bytes. Patch by Antoine Pitrou.
585
Gerhard Häringf9cee222010-03-05 15:20:03 +0000586- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
587 bugs and allows loading SQLite extensions from shared libraries.

634 exception of canonical and is_canonical) now accept instances of int
635 and long wherever a Decimal instance is accepted, and implicitly

660 file position when calling `truncate()`. It would previously change the
661 file position to the given argument, which goes against the tradition of
662 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

668 It also solves an issue where interleaved calls to `read()` and
669 `readline()` give wrong results. Patch by Nir Aides.

833 to execute file paths that refer to source or compiled Python files as well
834 as zipfiles, directories and other valid sys.path entries that contain a

836 support the same flexibility as the CPython command line itself.
837
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000838- Issue #7318: multiprocessing now uses a timeout when it fails to establish

1303 calling methods on the object.
1304
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001305- Issue #7222: Make thread "reaping" more reliable so that reference
1306 leak-chasing test runs give sensible results. The previous method of
1307 reaping threads could return successfully while some Thread objects were
1308 still referenced. This also introduces a new private function:
1309 :func:`_thread._count()`.
1310
R. David Murray27144602009-10-19 15:26:16 +00001311- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1313
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001314- Issue #7055: test___all__ now greedily detects all modules which have an

1319 and a new section in the summary report at the end.

1322
Brett Cannon3c273842009-07-20 00:14:29 +00001323- Fixed tests in importlib.test.source.test_abc_loader that were masking
1324 the proper exceptions that should be raised for missing or improper code
1325 object bytecode.
1326

Antoine Pitroue4501852009-05-14 18:55:55 +00001542- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1543 library. This means, for example, that opening an UTF-16 text file in
1544 append mode doesn't add a BOM at the end of the file if the file isn't
1545 empty.

1595Core and Builtins
1596-----------------
1597
Mark Dickinson865e01a2009-05-07 16:37:01 +00001598- Issue #5914: Add new C API function PyOS_string_to_double, and
1599 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1600
Eric Smith741191f2009-05-06 13:08:15 +00001601- Issue #3382: float.__format__, complex.__format__, and %-formatting
1602 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1603 affects nan -> NAN and inf -> INF.
1604
Mark Hammond5a607a32009-05-06 08:04:54 +00001605- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1606 in all operations, including splitdrive, split, etc. splitunc() now issues
1607 a PendingDeprecation warning.
1608
Eric Smith63376222009-05-05 14:04:18 +00001609- Issue #5920: For float.__format__, change the behavior with the
1610 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1611 to be like 'g' but with at least one decimal point and with a
1612 default precision of 12. Previously, the behavior the same but with
1613 a default precision of 6. This more closely matches str(), and
1614 reduces surprises when adding alignment flags to the empty
1615 presentation type. This also affects the new complex.__format__ in
1616 the same way.
1617
Martin v. Löwis011e8422009-05-05 04:43:17 +00001618- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1619
R. David Murrayb18500d2009-05-04 22:59:07 +00001620- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1621 shadowed by classtype's, even if it was None. property now
1622 inserts the __doc__ into the subclass instance __dict__.
1623
Antoine Pitrou244651a2009-05-04 18:56:13 +00001624- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1625 sequences. Patch by Nick Barnes and Victor Stinner.
1626
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001627- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001628
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001629- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1630 received a new method, detach(). detach() disconnects the underlying stream
1631 from the buffer or text IO and returns it.
1632
Mark Dickinson33841c32009-05-01 15:37:04 +00001633- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1634 floats with absolute value over 1e50. Also remove length
1635 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1636 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001637
Eric Smith741191f2009-05-06 13:08:15 +00001638- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001639 format(complex(1, 2./3), '.5') now produces a sensible result.
1640
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001641- Issue #5864: Fix empty format code formatting for floats so that it
1642 never gives more than the requested number of significant digits.
1643
Eric Smith6dc46f52009-04-27 20:39:49 +00001644- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1645 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1646
Eric Smithcc32a112009-04-26 21:35:14 +00001647- Issue #5835: Deprecate PyOS_ascii_formatd.
1648
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001649- Issue #4971: Fix titlecase for characters that are their own
1650 titlecase, but not their own uppercase.
1651
Benjamin Peterson193152c2009-04-25 01:08:45 +00001652- Issue #5283: Setting __class__ in __del__ caused a segfault.
1653
Mark Dickinsonad476da2009-04-23 19:14:16 +00001654- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1655 z involves nans, infs or negative zeros.
1656
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001657- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001658
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001659- Issue #1869 (and many duplicates): make round(x, n) correctly
1660 rounded for a float x, by using the decimal <-> binary conversions
1661 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1662 consistently agrees with format(x, '.2f').
1663
Benjamin Petersonae937c02009-04-18 20:54:08 +00001664- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1665 some builtin types.
1666
Eric Smith0923d1d2009-04-16 20:16:10 +00001667- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1668
Eric Smith35e84722009-04-16 20:21:28 +00001669- Issue #5515: str.format() type 'n' combined with commas and leading
1670 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001671
1672- Implement PEP 378, Format Specifier for Thousands Separator, for
1673 floats.
1674
Mark Dickinson3370cce2009-04-17 22:40:53 +00001675- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001676 1e11, not 1e12. This avoids printing 13 significant digits in
1677 situations where only 12 of them are correct. Example problem
1678 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1679 long time.)
1680
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001681- Issue #1580: On most platforms, use a 'short' float repr: for a
1682 finite float x, repr(x) now outputs a string based on the shortest
1683 sequence of decimal digits that rounds to x. Previous behaviour was
1684 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001685 Another minor difference is that the new repr switches to
1686 exponential notation at 1e16 instead of the previous 1e17; this
1687 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001688
1689 There's a new sys attribute sys.float_repr_style, which takes
1690 the value 'short' to indicate that we're using short float repr,
1691 and 'legacy' if the short float repr isn't available for one
1692 reason or another.
1693
1694 The float repr change involves incorporating David Gay's 'perfect
1695 rounding' code into the Python core (it's in Python/dtoa.c). As a
1696 secondary consequence, all string-to-float and float-to-string
1697 conversions (including all float formatting operations) will be
1698 correctly rounded on these platforms.
1699
1700 See issue 1580 discussions for details of platforms for which
1701 this change does not apply.
1702
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001703- Issue #5759: float() didn't call __float__ on str subclasses.
1704
Georg Brandlabc38772009-04-12 15:51:51 +00001705- The string.maketrans() function is deprecated; there is a new static method
1706 maketrans() on the bytes and bytearray classes. This removes confusion about
1707 the types string.maketrans() is supposed to work with, and mirrors the
1708 methods available on the str class.
1709
R. David Murraydc6da8a2009-04-09 22:16:43 +00001710- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1711 its clarity and its speed.
1712
Matthias Klose091c7b12009-04-07 13:24:27 +00001713- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1714 to avoid compiler warnings.
1715
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001716- Issue #3739: The unicode-internal encoder now reports the number of characters
1717 consumed like any other encoder (instead of the number of bytes).

1796 results in a handle_expt_event call, not handle_read_event, and POLLERR
1797 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1798 dispatcher now has an 'ignore_log_types' attribute for suppressing
1799 log messages, which is set to 'warning' by default.

1875 untrackable objects are not tracked by the garbage collector. This can
1876 reduce the size of collections and therefore the garbage collection overhead
1877 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +00001947- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
1948 forever on incomplete input. That caused tarfile.open() to hang when used
1949 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
1950 partial bzip2 compressed data.

2067 flag to work properly. Furthermore, when specifying -u, the text stdout
2068 and stderr streams have line-by-line buffering enabled (the default being
2069 to buffer arbitrary chunks of data).

Antoine Pitrou08838b62009-01-21 00:55:13 +00002473- Issue #5008: When a file is opened in append mode with the new IO library,
2474 do an explicit seek to the end of file (so that e.g. tell() returns the
