104 deprecations.
105
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000106- Issue #7385: Fix a crash in `MemoryView_FromObject` when

108
Mark Dickinsonbc099642010-01-29 17:27:24 +0000109- Issue #7788: Fix an interpreter crash produced by deleting a list
110 slice with very large step value.
111
Eric Smithf7bb5782010-01-27 00:44:57 +0000112- Issue #7766: Change sys.getwindowsversion() return value to a named
113 tuple and add the additional members returned in an OSVERSIONINFOEX

116
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

152 negative zero) in ** operator. The behaviour now conforms to that
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

Georg Brandl1e28a272009-12-28 08:41:01 +0000317- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
318
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000319- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
320 in PyArg_ParseTupleAndKeywords.
321
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000322- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)
Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000323 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
324
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000325- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
326 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
327 should used for accessing the d_type and d_name members of structures
328 using PyDescr_COMMON.
329
330- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000331

333
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000334- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
335 PyCode_Addr2Line().
336
337- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
338 object at a specified file, function, and line number.
339
340- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
341 ``const char *`` as the string is stored beyond the call.
342
Benjamin Peterson05159c42009-12-03 03:01:27 +0000343- Issue #2422: When compiled with the ``--with-valgrind`` option, the
344 pymalloc allocator will be automatically disabled when running under
345 Valgrind. This gives improved memory leak detection when running
346 under Valgrind, while taking advantage of pymalloc at other times.

350
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000351- Issue #8567: Fix precedence of signals in Decimal module: when a
352 Decimal operation raises multiple signals and more than one of those
353 signals is trapped, the specification determines the order in which
354 the signals should be handled. In many cases this order wasn't
355 being followed, leading to the wrong Python exception being raised.
356
Antoine Pitrou6be88762010-05-03 16:48:20 +0000357- Issue #7865: The close() method of :mod:`io` objects should not swallow
358 exceptions raised by the implicit flush(). Also ensure that calling
359 close() several times is supported. Patch by Pascal Chambon.
360
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000361- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
362 gc.DEBUG_STATS.
363
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000364- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
365 webbrowser.get("safari").
366
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000367- Issue #8464: tarfile no longer creates files with execute permissions set
368 when mode="w|" is used.
369
Antoine Pitroubf043492010-04-29 10:11:46 +0000370- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
371 of the Linux kernel. Patch by Yaniv Aknin.
372
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000373- Issue #8295: Added shutil.unpack_archive.
374
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000375- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
376 It should correctly return an empty response now.
377
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000378- Issue #8546: Reject None given as the buffering argument to _pyio.open.
379
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000380- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
381 Sridhar Ratnakumar.
382
R. David Murrayad78d152010-04-27 02:45:53 +0000383- Issue #6656: fix locale.format_string to handle escaped percents
384 and mappings.
385
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000386- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
387 where the method could block indefinitely if called just before the
388 event loop started running. This also fixes the occasional freezes
389 witnessed in test_httpservers.
390
Antoine Pitrou40f08742010-04-24 22:04:40 +0000391- Issue #8524: When creating an SSL socket, the timeout value of the
392 original socket wasn't retained (instead, a socket with a positive timeout
393 would be turned into a non-blocking SSL socket).
394
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000395- Issue #5103: SSL handshake would ignore the socket timeout and block
396 indefinitely if the other end didn't respond.
397
398- The do_handshake() method of SSL objects now adjusts the blocking mode of
399 the SSL structure if necessary (as other methods already do).
400
Victor Stinner13bb71c2010-04-23 21:41:56 +0000401- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
402 and bytes strings for environment keys and values
403
Victor Stinner4d078042010-04-23 19:28:32 +0000404- Issue #8467: Pure Python implementation of subprocess encodes the error
405 message using surrogatepass error handler to support surrogates in the
406 message
407
Victor Stinner349fd522010-04-23 10:56:17 +0000408- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
409
Sean Reifscheider13daf122010-04-23 09:29:52 +0000410- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
411 the string "python" as the *ident*. openlog() arguments are all optional
412 and keywords.
413
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000414- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
415 a non-infinite timeout. Also make that method friendlier with applications
416 wanting to continue using the socket in clear-text mode, by disabling
417 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
418
Antoine Pitrou7062db82010-04-22 13:30:10 +0000419- Issue #8496: make mailcap.lookup() always return a list, rather than an
420 iterator. Patch by Gregory Nofi.
421
Victor Stinner35466c52010-04-22 11:23:23 +0000422- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
423 collation name contains a surrogate character.
424
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000425- Issue #8484: Load all ciphers and digest algorithms when initializing
426 the _ssl extension, such that verification of some SSL certificates
427 doesn't fail because of an "unknown algorithm".
428
Tarek Ziadéfb437512010-04-20 08:57:33 +0000429- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
430
Tarek Ziadé5340db32010-04-19 22:30:51 +0000431- Issue #1540112: Now allowing the choice of a copy function in
432 shutil.copytree.
433
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000434- Issue #4814: timeout parameter is now applied also for connections resulting
435 from PORT/EPRT commands.
436
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000437- Issue #8463: added missing reference to bztar in shutil's documentation.
438
Ronald Oussoren84151202010-04-18 20:46:11 +0000439- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
440 (as long as the user didn't specify 'automatic proxy configuration').
441
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000442- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
443 code as stated in RFC-959 at chapter 5.4.
444
Victor Stinner738446f02010-04-18 00:00:44 +0000445- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
446 surrogates.
447
Antoine Pitrou0454af92010-04-17 23:51:58 +0000448- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000449 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000450
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000451- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
452 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
453
Victor Stinner0e59cc32010-04-16 23:49:32 +0000454- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
455 the current working directory.
456
Victor Stinner5bfe1462010-04-16 13:28:05 +0000457- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
458 using backslashreplace error handler
459
Victor Stinnercfa72782010-04-16 11:45:13 +0000460- Issue #8412: os.system() now accepts bytes, bytearray and str with
461 surrogates.
462
Senthil Kumaranad02d232010-04-16 03:02:13 +0000463- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
464 Locke and Hans Ulrich Niedermann.
465
R. David Murrayd48739f2010-04-14 18:59:18 +0000466- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
467
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000468- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
469 module now takes an optional timeout argument in seconds. Timeout support
470 relies on the system threading library, so as to avoid a semi-busy wait
471 loop.
472
Victor Stinner485fb562010-04-13 11:07:24 +0000473- Issue #8383: pickle and pickletools use surrogatepass error handler when
474 encoding unicode as utf8 to support lone surrogates and stay compatible with
475 Python 2.x and 3.0
476
R. David Murrayb2416e52010-04-12 16:58:02 +0000477- Issue #7585: difflib context and unified diffs now place a tab between
478 filename and date, conforming to the 'standards' they were originally
479 designed to follow. This improves compatibility with patch tools.
480
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000481- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
482 character sets will now consistently use a Content-Transfer-Encoding of
483 7bit rather than sometimes being marked as 8bit.
484
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000485- Issue #8375: test_distutils now checks if the temporary directory are still
486 present before it cleans them.
487
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000488- Issue #8374: Update the internal alias table in the :mod:`locale` module
489 to cover recent locale changes and additions.
490
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000491- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
492 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
493 and `ssl.OPENSSL_VERSION_NUMBER`.
494
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000495- Add functools.total_ordering() and functools.cmp_to_key().
496
Mark Dickinson089b00c2010-04-03 15:51:03 +0000497- Issue #8257: The Decimal construct now accepts a float instance
498 directly, converting that float to a Decimal of equal value:
499
500 >>> Decimal(1.1)
501 Decimal('1.100000000000000088817841970012523233890533447265625')
502
Mark Dickinson98127c32010-04-03 11:18:52 +0000503- Issue #8294: The Fraction constructor now accepts Decimal and float
504 instances directly.
505
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000506- Issue #7279: Comparisons involving a Decimal signaling NaN now
507 signal InvalidOperation instead of returning False. (Comparisons
508 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
509 are now hashable; Decimal signaling NaNs remain unhashable.
510
511- Issue #2531: Comparison operations between floats and Decimal
512 instances now return a result based on the numeric values of the
513 operands; previously they returned an arbitrary result based on
514 the relative ordering of id(float) and id(Decimal).
515
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000516- Added a subtract() method to collections.Counter().
517
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000518- Issue #8233: When run as a script, py_compile.py optionally takes a single
519 argument `-` which tells it to read files to compile from stdin. Each line
520 is read on demand and the named file is compiled immediately. (Original
521 patch by Piotr Ożarowski).
522
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000523- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
524 form feed (0x0C) are now considered linebreaks, as specified in Unicode
525 Standard Annex #14. See issue #7643.
526 http://www.unicode.org/reports/tr14/
527
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000528- Comparisons using one of <, <=, >, >= between a complex instance and
529 a Fractions instance now raise TypeError instead of returning
530 True/False. This makes Fraction <=> complex comparisons consistent with
531 int <=> complex, float <=> complex, and complex <=> complex comparisons.
532
Antoine Pitrou39b35432010-03-23 00:25:54 +0000533- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
534 some methods (such as oss_mixer_device.fileno()) were not available.
535 Initial patch by Bertrand Janin.
536
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000537- Issue #8205: Remove the "Modules" directory from sys.path when Python is
538 running from the build directory (POSIX only).
539
Antoine Pitrou910bd512010-03-22 20:11:09 +0000540- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
541 didn't support chflags() (for example ZFS under FreeBSD). The error is
542 now silenced.
543
R. David Murrayca2edce2010-03-22 17:48:48 +0000544- Issue #7860: platform.uname now reports the correct 'machine' type
545 when Python is running in WOW64 mode on 64 bit Windows.
546
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000547- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
548 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
549 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000550
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000551- Issue #4282: Fix the main function of the profile module for a non-ASCII
552 script, open the file in binary mode and not in text mode with the default
553 (utf8) encoding.
554
Florent Xicluna54467e02010-03-21 12:29:50 +0000555- Issue #8179: Fix macpath.realpath() on a non-existing path.
556
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000557- Issue #8024: Update the Unicode database to 5.2.

560
Benjamin Peterson689a5582010-03-18 22:29:52 +0000561- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
562 detected.
563
Martin v. Löwis4b003072010-03-16 13:19:21 +0000564- Issue #6716/2: Backslash-replace error output in compilall.
565
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000566- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
567 with Tcl/Tk-8.5.
568
Matthias Klosec33b9022010-03-16 00:36:26 +0000569- Issue #8140: extend compileall to compile single files. Add -i option.

572 the locale.
573
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000574- The internals of the subprocess module on POSIX systems have been replaced
575 by an extension module (_posixsubprocess) so that the fork()+exec() can be
576 done safely without the possibility of deadlock in multithreaded applications.
577
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000578- subprocess.Popen now has restore_signals and start_new_session features.
579 The default of restore_signals=True is a new behavior compared to earlier
580 Python versions. This means that signals such as SIGPIPE are not ignored
581 by default in subprocesses launched by Python (Issue #1652).
582
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000583- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
584 cElementTree module is updated too.
585
Victor Stinnerb33062c2010-03-12 14:27:16 +0000586- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to

Ezio Melottib92ed7c2010-03-06 15:24:08 +0000592- Issue #6509: fix re.sub to work properly when the pattern, the string, and
593 the replacement were all bytes. Patch by Antoine Pitrou.
594
Gerhard Häringf9cee222010-03-05 15:20:03 +0000595- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
596 bugs and allows loading SQLite extensions from shared libraries.
597
Ezio Melottida227042010-03-14 11:51:00 +0000598- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

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

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

1312 calling methods on the object.
1313
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001314- Issue #7222: Make thread "reaping" more reliable so that reference
1315 leak-chasing test runs give sensible results. The previous method of
1316 reaping threads could return successfully while some Thread objects were
1317 still referenced. This also introduces a new private function:
1318 :func:`_thread._count()`.
1319
R. David Murray27144602009-10-19 15:26:16 +00001320- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1322
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001323- Issue #7055: test___all__ now greedily detects all modules which have an

1328 and a new section in the summary report at the end.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001497- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1498 (1) inf and nan strings with trailing whitespace were incorrectly
1499 rejected; (2) parsing of strings representing infinities and nans
1500 was locale aware; and (3) the interpretation of fromhex('-nan')
1501 didn't match that of float('-nan').

1604Core and Builtins
1605-----------------
1606
Mark Dickinson865e01a2009-05-07 16:37:01 +00001607- Issue #5914: Add new C API function PyOS_string_to_double, and
1608 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1609
Eric Smith741191f2009-05-06 13:08:15 +00001610- Issue #3382: float.__format__, complex.__format__, and %-formatting
1611 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1612 affects nan -> NAN and inf -> INF.
1613
Mark Hammond5a607a32009-05-06 08:04:54 +00001614- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1615 in all operations, including splitdrive, split, etc. splitunc() now issues
1616 a PendingDeprecation warning.
1617
Eric Smith63376222009-05-05 14:04:18 +00001618- Issue #5920: For float.__format__, change the behavior with the
1619 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1620 to be like 'g' but with at least one decimal point and with a
1621 default precision of 12. Previously, the behavior the same but with
1622 a default precision of 6. This more closely matches str(), and
1623 reduces surprises when adding alignment flags to the empty
1624 presentation type. This also affects the new complex.__format__ in
1625 the same way.
1626
Martin v. Löwis011e8422009-05-05 04:43:17 +00001627- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1628
R. David Murrayb18500d2009-05-04 22:59:07 +00001629- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1630 shadowed by classtype's, even if it was None. property now
1631 inserts the __doc__ into the subclass instance __dict__.
1632
Antoine Pitrou244651a2009-05-04 18:56:13 +00001633- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1634 sequences. Patch by Nick Barnes and Victor Stinner.
1635
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001636- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001637
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001638- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1639 received a new method, detach(). detach() disconnects the underlying stream
1640 from the buffer or text IO and returns it.
1641
Mark Dickinson33841c32009-05-01 15:37:04 +00001642- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1643 floats with absolute value over 1e50. Also remove length
1644 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1645 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001646
Eric Smith741191f2009-05-06 13:08:15 +00001647- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001648 format(complex(1, 2./3), '.5') now produces a sensible result.
1649
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001650- Issue #5864: Fix empty format code formatting for floats so that it
1651 never gives more than the requested number of significant digits.
1652
Eric Smith6dc46f52009-04-27 20:39:49 +00001653- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1654 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1655
Eric Smithcc32a112009-04-26 21:35:14 +00001656- Issue #5835: Deprecate PyOS_ascii_formatd.
1657
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001658- Issue #4971: Fix titlecase for characters that are their own
1659 titlecase, but not their own uppercase.
1660
Benjamin Peterson193152c2009-04-25 01:08:45 +00001661- Issue #5283: Setting __class__ in __del__ caused a segfault.
1662
Mark Dickinsonad476da2009-04-23 19:14:16 +00001663- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1664 z involves nans, infs or negative zeros.
1665
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001666- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001667
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001668- Issue #1869 (and many duplicates): make round(x, n) correctly
1669 rounded for a float x, by using the decimal <-> binary conversions
1670 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1671 consistently agrees with format(x, '.2f').
1672
Benjamin Petersonae937c02009-04-18 20:54:08 +00001673- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1674 some builtin types.
1675
Eric Smith0923d1d2009-04-16 20:16:10 +00001676- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1677
Eric Smith35e84722009-04-16 20:21:28 +00001678- Issue #5515: str.format() type 'n' combined with commas and leading
1679 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001680
1681- Implement PEP 378, Format Specifier for Thousands Separator, for
1682 floats.
1683
Mark Dickinson3370cce2009-04-17 22:40:53 +00001684- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001685 1e11, not 1e12. This avoids printing 13 significant digits in
1686 situations where only 12 of them are correct. Example problem
1687 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1688 long time.)
1689
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001690- Issue #1580: On most platforms, use a 'short' float repr: for a
1691 finite float x, repr(x) now outputs a string based on the shortest
1692 sequence of decimal digits that rounds to x. Previous behaviour was
1693 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001694 Another minor difference is that the new repr switches to
1695 exponential notation at 1e16 instead of the previous 1e17; this
1696 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001697
1698 There's a new sys attribute sys.float_repr_style, which takes
1699 the value 'short' to indicate that we're using short float repr,
1700 and 'legacy' if the short float repr isn't available for one
1701 reason or another.
1702
1703 The float repr change involves incorporating David Gay's 'perfect
1704 rounding' code into the Python core (it's in Python/dtoa.c). As a
1705 secondary consequence, all string-to-float and float-to-string
1706 conversions (including all float formatting operations) will be
1707 correctly rounded on these platforms.
1708
1709 See issue 1580 discussions for details of platforms for which
1710 this change does not apply.
1711
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001712- Issue #5759: float() didn't call __float__ on str subclasses.
1713
Georg Brandlabc38772009-04-12 15:51:51 +00001714- The string.maketrans() function is deprecated; there is a new static method
1715 maketrans() on the bytes and bytearray classes. This removes confusion about
1716 the types string.maketrans() is supposed to work with, and mirrors the
1717 methods available on the str class.
1718
R. David Murraydc6da8a2009-04-09 22:16:43 +00001719- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1720 its clarity and its speed.
1721
Matthias Klose091c7b12009-04-07 13:24:27 +00001722- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1723 to avoid compiler warnings.
1724
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001725- Issue #3739: The unicode-internal encoder now reports the number of characters
1726 consumed like any other encoder (instead of the number of bytes).

1805 results in a handle_expt_event call, not handle_read_event, and POLLERR
1806 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1807 dispatcher now has an 'ignore_log_types' attribute for suppressing
1808 log messages, which is set to 'warning' by default.

1884 untrackable objects are not tracked by the garbage collector. This can
1885 reduce the size of collections and therefore the garbage collection overhead

2136 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

2148 method on file objects with closefd=False. The file descriptor is still
2149 kept open but the file object behaves like a closed file. The ``FileIO``
2150 object also got a new readonly attribute ``closefd``.

2160 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2161 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2162 of using the replace error handler in PyUnicode_DecodeUTF8().

2483 do an explicit seek to the end of file (so that e.g. tell() returns the
