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

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

Mark Dickinsonde604012010-01-01 19:27:32 +0000313- Issue #5080: The argument parsing functions PyArg_ParseTuple,
314 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
315 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
316 DeprecationWarning for float arguments passed with the 'L' format
317 code. This will become a TypeError in a future version of Python,
318 to match the behaviour of the other integer format codes.
319
Georg Brandl1e28a272009-12-28 08:41:01 +0000320- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
321
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000322- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
323 in PyArg_ParseTupleAndKeywords.
324
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000325- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)
Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000326 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
327
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000328- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
329 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
330 should used for accessing the d_type and d_name members of structures
331 using PyDescr_COMMON.
332
333- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000334
Benjamin Peterson466a7822009-07-02 21:44:01 +0000335- The code flags for old __future__ features are now available again.
336
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000337- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
338 PyCode_Addr2Line().
339
340- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
341 object at a specified file, function, and line number.
342
343- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
344 ``const char *`` as the string is stored beyond the call.
345
Benjamin Peterson05159c42009-12-03 03:01:27 +0000346- Issue #2422: When compiled with the ``--with-valgrind`` option, the
347 pymalloc allocator will be automatically disabled when running under
348 Valgrind. This gives improved memory leak detection when running
349 under Valgrind, while taking advantage of pymalloc at other times.

Victor Stinner449c4662010-05-08 11:10:09 +0000354- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
355 for use in the file system, environment variables or the command line.
356
Antoine Pitrou89562712010-05-07 17:04:02 +0000357- Issue #8571: Fix an internal error when compressing or decompressing a
358 chunk larger than 1GB with the zlib module's compressor and decompressor
359 objects.
360
Benjamin Peterson225168e2010-05-06 22:29:53 +0000361- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
362 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
363 file system encoding with the surrogateescape error handler (instead of
364 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000365
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000366- Issue #8573: asyncore _strerror() function might throw ValueError.
367
368- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
369 error messages when accessing undefined class attributes because of the cheap
370 inheritance with the underlying socket object.
371 The cheap inheritance has been deprecated.
372
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000373- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
374 Patch by Tres Seaver.
375
Victor Stinnerde629d42010-05-05 21:43:57 +0000376- Issue #8390: tarfile uses surrogateespace as the default error handler
377 (instead of replace in read mode or strict in write mode)
378
Barry Warsaw83d89982010-05-05 16:18:31 +0000379- Issue #7755: Use an unencumbered audio file for tests.
380
Ronald Oussorenac764d32010-05-05 15:32:33 +0000381- Issue #8621: uuid.uuid4() returned the same sequence of values in the
382 parent and any children created using ``os.fork`` on MacOS X 10.6.
383
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000384- Issue #8567: Fix precedence of signals in Decimal module: when a
385 Decimal operation raises multiple signals and more than one of those
386 signals is trapped, the specification determines the order in which
387 the signals should be handled. In many cases this order wasn't
388 being followed, leading to the wrong Python exception being raised.
389
Antoine Pitrou6be88762010-05-03 16:48:20 +0000390- Issue #7865: The close() method of :mod:`io` objects should not swallow
391 exceptions raised by the implicit flush(). Also ensure that calling
392 close() several times is supported. Patch by Pascal Chambon.
393
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000394- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
395 gc.DEBUG_STATS.
396
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000397- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
398 webbrowser.get("safari").
399
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000400- Issue #8464: tarfile no longer creates files with execute permissions set
401 when mode="w|" is used.
402
Antoine Pitroubf043492010-04-29 10:11:46 +0000403- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
404 of the Linux kernel. Patch by Yaniv Aknin.
405
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000406- Issue #8295: Added shutil.unpack_archive.
407
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000408- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
409 It should correctly return an empty response now.
410
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000411- Issue #8546: Reject None given as the buffering argument to _pyio.open.
412
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000413- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
414 Sridhar Ratnakumar.
415
R. David Murrayad78d152010-04-27 02:45:53 +0000416- Issue #6656: fix locale.format_string to handle escaped percents
417 and mappings.
418
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000419- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
420 where the method could block indefinitely if called just before the
421 event loop started running. This also fixes the occasional freezes
422 witnessed in test_httpservers.
423
Antoine Pitrou40f08742010-04-24 22:04:40 +0000424- Issue #8524: When creating an SSL socket, the timeout value of the
425 original socket wasn't retained (instead, a socket with a positive timeout
426 would be turned into a non-blocking SSL socket).
427
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000428- Issue #5103: SSL handshake would ignore the socket timeout and block
429 indefinitely if the other end didn't respond.
430
431- The do_handshake() method of SSL objects now adjusts the blocking mode of
432 the SSL structure if necessary (as other methods already do).
433
Victor Stinner13bb71c2010-04-23 21:41:56 +0000434- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
435 and bytes strings for environment keys and values
436
Victor Stinner4d078042010-04-23 19:28:32 +0000437- Issue #8467: Pure Python implementation of subprocess encodes the error
438 message using surrogatepass error handler to support surrogates in the
439 message
440
Victor Stinner349fd522010-04-23 10:56:17 +0000441- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
442
Sean Reifscheider13daf122010-04-23 09:29:52 +0000443- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
444 the string "python" as the *ident*. openlog() arguments are all optional
445 and keywords.
446
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000447- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
448 a non-infinite timeout. Also make that method friendlier with applications
449 wanting to continue using the socket in clear-text mode, by disabling
450 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
451
Antoine Pitrou7062db82010-04-22 13:30:10 +0000452- Issue #8496: make mailcap.lookup() always return a list, rather than an
453 iterator. Patch by Gregory Nofi.
454
Victor Stinner35466c52010-04-22 11:23:23 +0000455- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
456 collation name contains a surrogate character.
457
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000458- Issue #8484: Load all ciphers and digest algorithms when initializing
459 the _ssl extension, such that verification of some SSL certificates
460 doesn't fail because of an "unknown algorithm".
461
Tarek Ziadéfb437512010-04-20 08:57:33 +0000462- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
463
Tarek Ziadé5340db32010-04-19 22:30:51 +0000464- Issue #1540112: Now allowing the choice of a copy function in
465 shutil.copytree.
466
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000467- Issue #4814: timeout parameter is now applied also for connections resulting
468 from PORT/EPRT commands.
469
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000470- Issue #8463: added missing reference to bztar in shutil's documentation.
471
Ronald Oussoren84151202010-04-18 20:46:11 +0000472- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
473 (as long as the user didn't specify 'automatic proxy configuration').
474
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000475- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
476 code as stated in RFC-959 at chapter 5.4.
477
Victor Stinner738446f02010-04-18 00:00:44 +0000478- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
479 surrogates.
480
Antoine Pitrou0454af92010-04-17 23:51:58 +0000481- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000482 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000483
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000484- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
485 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
486
Victor Stinner0e59cc32010-04-16 23:49:32 +0000487- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
488 the current working directory.
489
Victor Stinner5bfe1462010-04-16 13:28:05 +0000490- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
491 using backslashreplace error handler
492
Victor Stinnercfa72782010-04-16 11:45:13 +0000493- Issue #8412: os.system() now accepts bytes, bytearray and str with
494 surrogates.
495
Senthil Kumaranad02d232010-04-16 03:02:13 +0000496- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
497 Locke and Hans Ulrich Niedermann.
498
R. David Murrayd48739f2010-04-14 18:59:18 +0000499- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
500
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000501- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
502 module now takes an optional timeout argument in seconds. Timeout support
503 relies on the system threading library, so as to avoid a semi-busy wait
504 loop.
505
Victor Stinner485fb562010-04-13 11:07:24 +0000506- Issue #8383: pickle and pickletools use surrogatepass error handler when
507 encoding unicode as utf8 to support lone surrogates and stay compatible with
508 Python 2.x and 3.0
509
R. David Murrayb2416e52010-04-12 16:58:02 +0000510- Issue #7585: difflib context and unified diffs now place a tab between
511 filename and date, conforming to the 'standards' they were originally
512 designed to follow. This improves compatibility with patch tools.
513
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000514- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
515 character sets will now consistently use a Content-Transfer-Encoding of
516 7bit rather than sometimes being marked as 8bit.
517
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000518- Issue #8375: test_distutils now checks if the temporary directory are still
519 present before it cleans them.
520
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000521- Issue #8374: Update the internal alias table in the :mod:`locale` module
522 to cover recent locale changes and additions.
523
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000524- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
525 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
526 and `ssl.OPENSSL_VERSION_NUMBER`.
527
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000528- Add functools.total_ordering() and functools.cmp_to_key().
529
Mark Dickinson089b00c2010-04-03 15:51:03 +0000530- Issue #8257: The Decimal construct now accepts a float instance
531 directly, converting that float to a Decimal of equal value:
532
533 >>> Decimal(1.1)
534 Decimal('1.100000000000000088817841970012523233890533447265625')
535
Mark Dickinson98127c32010-04-03 11:18:52 +0000536- Issue #8294: The Fraction constructor now accepts Decimal and float
537 instances directly.
538
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000539- Issue #7279: Comparisons involving a Decimal signaling NaN now
540 signal InvalidOperation instead of returning False. (Comparisons
541 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
542 are now hashable; Decimal signaling NaNs remain unhashable.
543
544- Issue #2531: Comparison operations between floats and Decimal
545 instances now return a result based on the numeric values of the
546 operands; previously they returned an arbitrary result based on
547 the relative ordering of id(float) and id(Decimal).
548
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000549- Added a subtract() method to collections.Counter().
550
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000551- Issue #8233: When run as a script, py_compile.py optionally takes a single
552 argument `-` which tells it to read files to compile from stdin. Each line
553 is read on demand and the named file is compiled immediately. (Original
554 patch by Piotr Ożarowski).
555
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000556- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
557 form feed (0x0C) are now considered linebreaks, as specified in Unicode
558 Standard Annex #14. See issue #7643.
559 http://www.unicode.org/reports/tr14/
560
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000561- Comparisons using one of <, <=, >, >= between a complex instance and
562 a Fractions instance now raise TypeError instead of returning
563 True/False. This makes Fraction <=> complex comparisons consistent with
564 int <=> complex, float <=> complex, and complex <=> complex comparisons.
565
Antoine Pitrou39b35432010-03-23 00:25:54 +0000566- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
567 some methods (such as oss_mixer_device.fileno()) were not available.
568 Initial patch by Bertrand Janin.
569
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000570- Issue #8205: Remove the "Modules" directory from sys.path when Python is
571 running from the build directory (POSIX only).
572
Antoine Pitrou910bd512010-03-22 20:11:09 +0000573- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
574 didn't support chflags() (for example ZFS under FreeBSD). The error is
575 now silenced.
576
R. David Murrayca2edce2010-03-22 17:48:48 +0000577- Issue #7860: platform.uname now reports the correct 'machine' type
578 when Python is running in WOW64 mode on 64 bit Windows.
579
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000580- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
581 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
582 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000583
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000584- Issue #4282: Fix the main function of the profile module for a non-ASCII
585 script, open the file in binary mode and not in text mode with the default
586 (utf8) encoding.
587
Florent Xicluna54467e02010-03-21 12:29:50 +0000588- Issue #8179: Fix macpath.realpath() on a non-existing path.
589
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000590- Issue #8024: Update the Unicode database to 5.2.
591
Benjamin Peterson00888932010-03-18 22:37:38 +0000592- Issue #8168: py_compile now handles files with utf-8 BOMS.
593
Benjamin Peterson689a5582010-03-18 22:29:52 +0000594- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
595 detected.
596
Martin v. Löwis4b003072010-03-16 13:19:21 +0000597- Issue #6716/2: Backslash-replace error output in compilall.
598
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000599- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
600 with Tcl/Tk-8.5.
601
Matthias Klosec33b9022010-03-16 00:36:26 +0000602- Issue #8140: extend compileall to compile single files. Add -i option.
603
Matthias Klose82f60912010-03-15 13:46:04 +0000604- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
605 the locale.
606
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000607- The internals of the subprocess module on POSIX systems have been replaced
608 by an extension module (_posixsubprocess) so that the fork()+exec() can be
609 done safely without the possibility of deadlock in multithreaded applications.
610
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000611- subprocess.Popen now has restore_signals and start_new_session features.
612 The default of restore_signals=True is a new behavior compared to earlier
613 Python versions. This means that signals such as SIGPIPE are not ignored
614 by default in subprocesses launched by Python (Issue #1652).
615
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000616- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
617 cElementTree module is updated too.
618
Victor Stinnerb33062c2010-03-12 14:27:16 +0000619- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
620 an non existent program name and Python is unable to retrieve the real

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

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000874- Issue #6816: runpy now provides a run_path function that allows Python code
875 to execute file paths that refer to source or compiled Python files as well
876 as zipfiles, directories and other valid sys.path entries that contain a
877 __main__.py file. This allows applications that run other Python scripts to
878 support the same flexibility as the CPython command line itself.
879
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000880- Issue #7318: multiprocessing now uses a timeout when it fails to establish
881 a connection with another process, rather than looping endlessly. The
882 default timeout is 20 seconds, which should be amply sufficient for

897 default when instantiating a `threading.RLock` object. This makes
898 recursive locks as fast as regular non-recursive locks (previously,
899 they were slower by 10x to 15x).
900
Antoine Pitroub0872682009-11-09 16:08:16 +0000901- Issue #7282: Fix a memory leak when an RLock was used in a thread other

Antoine Pitrou03f13442009-11-02 11:36:51 +0000914- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
915 a modification is done through it. This fixes inconsistencies and test
916 failures on systems with slightly bogus mtime behaviour.
917
Gregory P. Smith50467882009-11-01 18:42:17 +0000918- Issue #7246 & Issue #7208: getpass now properly flushes input before
919 reading from stdin so that existing input does not confuse it and
920 lead to incorrect entry or an IOError. It also properly flushes it
921 afterwards to avoid the terminal echoing the input afterwards on
922 OSes such as Solaris.

1352
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001353- Issue #7222: Make thread "reaping" more reliable so that reference
1354 leak-chasing test runs give sensible results. The previous method of
1355 reaping threads could return successfully while some Thread objects were
1356 still referenced. This also introduces a new private function:
1357 :func:`_thread._count()`.
1358
R. David Murray27144602009-10-19 15:26:16 +00001359- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1361
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001362- Issue #7055: test___all__ now greedily detects all modules which have an

1367 and a new section in the summary report at the end.

1370
Brett Cannon3c273842009-07-20 00:14:29 +00001371- Fixed tests in importlib.test.source.test_abc_loader that were masking

1512-----------------
1513
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001514- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1515 of the command line.
1516
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001517- Issue #6012: Add cleanup support to O& argument parsing.
1518
Eric Smith41669ca2009-05-23 14:23:22 +00001519- Issue #6089: Fixed str.format with certain invalid field specifiers
1520 that would raise SystemError.
1521
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001522- Issue #5982: staticmethod and classmethod now expose the wrapped
1523 function with __func__.
1524
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001525- Added support for multiple context managers in the same with-statement.
1526 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001527
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001528- Issue #5829: complex("1e500") no longer raises OverflowError. This
1529 makes it consistent with float("1e500") and interpretation of real
1530 and imaginary literals.
1531
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001532- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1533
R. David Murraydd226ea2009-05-13 12:27:21 +00001534- Issue #5994: the marshal module now has docstrings.
1535
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001536- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1537 (1) inf and nan strings with trailing whitespace were incorrectly
1538 rejected; (2) parsing of strings representing infinities and nans
1539 was locale aware; and (3) the interpretation of fromhex('-nan')
1540 didn't match that of float('-nan').

1548
R. David Murray1f1b9d32009-05-27 20:56:59 +00001549- Issue #6121: pydoc now ignores leading and trailing spaces in the
1550 argument to the 'help' function.
1551
Georg Brandlfaf41492009-05-26 18:31:11 +00001552- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1553 arguments for strings with a space in them.
1554
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001555- collections.namedtuple() was not working with the following field
1556 names: cls, self, tuple, itemgetter, and property.
1557
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001558- In unittest, using a skipping decorator on a class is now equivalent to
1559 skipping every test on the class. The ClassTestSuite class has been removed.
1560
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001561- Issue #6050: Don't fail extracting a directory from a zipfile if
1562 the directory already exists.
1563
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001564- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1565 than an int, which makes some operations possible under 64-bit Linux (e.g.
1566 DN_MULTISHOT with F_NOTIFY).
1567
Antoine Pitrou716c4442009-05-23 19:04:03 +00001568- Issue #5761: Add the name of the underlying file to the repr() of various
1569 IO objects.
1570
R. David Murraycaa27b72009-05-23 18:49:56 +00001571- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1572 by Musashi Tamura, tests by Marcin Bachry.
1573
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001574- Issue #1983: Fix functions taking or returning a process identifier to use
1575 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1576 a process identifier type wider than the standard C integer type.
1577
R. David Murray87e20742009-05-23 01:30:26 +00001578- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1582 deepcopy()ing.
1583
Antoine Pitrouc1d09362009-05-15 12:15:51 +00001584- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.

1587
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00001588- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
1589
Antoine Pitroue4501852009-05-14 18:55:55 +00001590- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1591 library. This means, for example, that opening an UTF-16 text file in
1592 append mode doesn't add a BOM at the end of the file if the file isn't
1593 empty.
1594
R. David Murray74b89242009-05-13 17:33:03 +00001595- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1596 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1597 corrects a pydoc regression.
1598
R. David Murray99352742009-05-07 18:24:38 +00001599- Issue 5955: aifc's close method did not close the file it wrapped,
1600 now it does. This also means getfp method now returns the real fp.
1601
Benjamin Peterson932073a2009-05-23 16:14:33 +00001602Installation
1603------------
1604
1605- Issue #6047: fullinstall has been removed because Python 3's executable will
1606 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001607
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001608- Lib/smtpd.py is no longer installed as a script.

1630-----
1631
1632- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1633 tests on darwin even when the OS was installed on a case-sensitive
1634 filesystem. Also fixed tests that should not be run when
1635 sys.dont_write_bytecode is true.

1637
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001638What's New in Python 3.1 beta 1?
1639================================
1640
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001641*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001642
1643Core and Builtins
1644-----------------
1645
Mark Dickinson865e01a2009-05-07 16:37:01 +00001646- Issue #5914: Add new C API function PyOS_string_to_double, and
1647 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1648
Eric Smith741191f2009-05-06 13:08:15 +00001649- Issue #3382: float.__format__, complex.__format__, and %-formatting
1650 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1651 affects nan -> NAN and inf -> INF.
1652
Mark Hammond5a607a32009-05-06 08:04:54 +00001653- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1654 in all operations, including splitdrive, split, etc. splitunc() now issues
1655 a PendingDeprecation warning.
1656
Eric Smith63376222009-05-05 14:04:18 +00001657- Issue #5920: For float.__format__, change the behavior with the
1658 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1659 to be like 'g' but with at least one decimal point and with a
1660 default precision of 12. Previously, the behavior the same but with
1661 a default precision of 6. This more closely matches str(), and
1662 reduces surprises when adding alignment flags to the empty
1663 presentation type. This also affects the new complex.__format__ in
1664 the same way.
1665
Martin v. Löwis011e8422009-05-05 04:43:17 +00001666- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1667
R. David Murrayb18500d2009-05-04 22:59:07 +00001668- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1669 shadowed by classtype's, even if it was None. property now
1670 inserts the __doc__ into the subclass instance __dict__.
1671
Antoine Pitrou244651a2009-05-04 18:56:13 +00001672- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1673 sequences. Patch by Nick Barnes and Victor Stinner.
1674
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001675- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001676
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001677- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1678 received a new method, detach(). detach() disconnects the underlying stream
1679 from the buffer or text IO and returns it.
1680
Mark Dickinson33841c32009-05-01 15:37:04 +00001681- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1682 floats with absolute value over 1e50. Also remove length
1683 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1684 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001685
Eric Smith741191f2009-05-06 13:08:15 +00001686- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001687 format(complex(1, 2./3), '.5') now produces a sensible result.
1688
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001689- Issue #5864: Fix empty format code formatting for floats so that it
1690 never gives more than the requested number of significant digits.
1691
Eric Smith6dc46f52009-04-27 20:39:49 +00001692- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1693 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1694
Eric Smithcc32a112009-04-26 21:35:14 +00001695- Issue #5835: Deprecate PyOS_ascii_formatd.
1696
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001697- Issue #4971: Fix titlecase for characters that are their own
1698 titlecase, but not their own uppercase.
1699
Benjamin Peterson193152c2009-04-25 01:08:45 +00001700- Issue #5283: Setting __class__ in __del__ caused a segfault.
1701
Mark Dickinsonad476da2009-04-23 19:14:16 +00001702- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1703 z involves nans, infs or negative zeros.
1704
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001705- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001706
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001707- Issue #1869 (and many duplicates): make round(x, n) correctly
1708 rounded for a float x, by using the decimal <-> binary conversions
1709 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1710 consistently agrees with format(x, '.2f').
1711
Benjamin Petersonae937c02009-04-18 20:54:08 +00001712- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1713 some builtin types.
1714
Eric Smith0923d1d2009-04-16 20:16:10 +00001715- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1716
Eric Smith35e84722009-04-16 20:21:28 +00001717- Issue #5515: str.format() type 'n' combined with commas and leading
1718 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001719
1720- Implement PEP 378, Format Specifier for Thousands Separator, for
1721 floats.
1722
Mark Dickinson3370cce2009-04-17 22:40:53 +00001723- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001724 1e11, not 1e12. This avoids printing 13 significant digits in
1725 situations where only 12 of them are correct. Example problem
1726 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1727 long time.)
1728
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001729- Issue #1580: On most platforms, use a 'short' float repr: for a
1730 finite float x, repr(x) now outputs a string based on the shortest
1731 sequence of decimal digits that rounds to x. Previous behaviour was
1732 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001733 Another minor difference is that the new repr switches to
1734 exponential notation at 1e16 instead of the previous 1e17; this
1735 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001736
1737 There's a new sys attribute sys.float_repr_style, which takes
1738 the value 'short' to indicate that we're using short float repr,
1739 and 'legacy' if the short float repr isn't available for one
1740 reason or another.
1741
1742 The float repr change involves incorporating David Gay's 'perfect
1743 rounding' code into the Python core (it's in Python/dtoa.c). As a
1744 secondary consequence, all string-to-float and float-to-string
1745 conversions (including all float formatting operations) will be
1746 correctly rounded on these platforms.
1747
1748 See issue 1580 discussions for details of platforms for which
1749 this change does not apply.
1750
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001751- Issue #5759: float() didn't call __float__ on str subclasses.
1752
Georg Brandlabc38772009-04-12 15:51:51 +00001753- The string.maketrans() function is deprecated; there is a new static method
1754 maketrans() on the bytes and bytearray classes. This removes confusion about
1755 the types string.maketrans() is supposed to work with, and mirrors the
1756 methods available on the str class.
1757
R. David Murraydc6da8a2009-04-09 22:16:43 +00001758- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1759 its clarity and its speed.
1760
Matthias Klose091c7b12009-04-07 13:24:27 +00001761- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1762 to avoid compiler warnings.
1763
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001764- Issue #3739: The unicode-internal encoder now reports the number of characters
1765 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002085- Issue #4935: The overflow checking code in the expandtabs() method common
2086 to str, bytes and bytearray could be optimized away by the compiler, letting
2087 the interpreter segfault instead of raising an error.
2088
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002089- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2090 __next__ method.
2091
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002092- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2093 function no longer attempt to call the __long__ slot to convert an object
2094 to an integer. Only the __int__ and __trunc__ slots are examined.
2095
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002096- Issue #4893: Use NT threading on CE.

2099
Antoine Pitrouab868312009-01-10 15:40:25 +00002100- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2101 common cases are optimized thanks to a dedicated fast path and a moderate
2102 amount of loop unrolling.
2103
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002104- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2105 collecting the oldest generation) so that allocating lots of objects without
2106 destroying them does not show quadratic performance. Based on a proposal by
2107 Martin von Löwis at
2108 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2109
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002110- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002111 having been closed (for instance, a read() call could return some
2112 previously buffered data). Patch by Dmitry Vasiliev.
2113
Antoine Pitrou05608432009-01-09 18:53:14 +00002114- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2115 flag to work properly. Furthermore, when specifying -u, the text stdout
2116 and stderr streams have line-by-line buffering enabled (the default being
2117 to buffer arbitrary chunks of data).
2118
Raymond Hettinger35631532009-01-09 03:58:09 +00002119- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2120 instead of ints (reducing its size from 4 to 8 times thereby reducing
2121 Python's overall memory).
2122
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002123- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2124 an existing .py counterpart, override the co_filename attributes of all
2125 code objects if the original filename is obsolete (which can happen if the
2126 file has been renamed, moved, or if it is accessed through different paths).
2127 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2128
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002129- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2130 one byte. Also fixes the meaning of len() so that it returns the number of
2131 items, rather than the size in bytes.
2132
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002133- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2134
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002135- Issue #4747: When the terminal does not use utf-8, executing a script with
2136 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2137
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002138- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002139 file with `bytes' filename on Windows.

Antoine Pitrou7ddda782009-01-01 15:35:33 +00002141- Issue #3680: Reference cycles created through a dict, set or deque iterator
2142 did not get collected.
2143
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002144- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2145 where the tp_hash and tp_dict slots are both NULL.
2146
Georg Brandlccc47b62008-12-28 11:44:14 +00002147- Issue #4759: None is now allowed as the first argument of
2148 bytearray.translate(). It was always allowed for bytes.translate().
2149
Skip Montanaro80072cb2008-12-23 03:51:14 +00002150- Added test case to ensure attempts to read from a file opened for writing
2151 fail.
2152
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002153- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002155- Issue #2183: Simplify and optimize bytecode for list, dict and set
2156 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2157
Antoine Pitrou621601a2008-12-17 23:18:19 +00002158- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2160 unreachable. Original patch by Neil Schemenauer.
2161
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002162- Issue #3439: Add a bit_length method to int.
2163
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002164- Issue #2173: When getting device encoding, check that return value of
2165 nl_langinfo is not the empty string. This was causing silent build
2166 failures on OS X.
2167
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002168- Issue #4597: Fixed several opcodes that weren't always propagating
2169 exceptions.
2170
2171- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002172 context manager returns a value that cannot be converted to a bool.
2173
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002174- Issue #4445: Replace "sizeof(PyBytesObject)" with
2175 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2176 bytes instances. On a typical machine this saves 3 bytes of memory
2177 (on average) per allocation of a bytes instance.
2178
Christian Heimesa872de52008-12-05 08:26:55 +00002179- Issue #4533: File read operation was dreadfully slow due to a slowly
2180 growing read buffer. Fixed by using the same growth rate algorithm as
2181 Python 2.x.
2182
Antoine Pitrou5504e892008-12-06 21:27:53 +00002183- Issue #4509: Various issues surrounding resize of bytearray objects to
2184 which there are buffer exports (e.g. memoryview instances).
2185
Georg Brandlf9734072008-12-07 15:30:06 +00002186- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2187 method on file objects with closefd=False. The file descriptor is still
2188 kept open but the file object behaves like a closed file. The ``FileIO``
2189 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002191- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2197
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002198- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2199 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2200 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2201 of using the replace error handler in PyUnicode_DecodeUTF8().
