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.

355 chunk larger than 1GB with the zlib module's compressor and decompressor
356 objects.
357
Benjamin Peterson225168e2010-05-06 22:29:53 +0000358- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
359 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
360 file system encoding with the surrogateescape error handler (instead of
361 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000363- Issue #8573: asyncore _strerror() function might throw ValueError.
364
365- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
366 error messages when accessing undefined class attributes because of the cheap
367 inheritance with the underlying socket object.
368 The cheap inheritance has been deprecated.
369
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000370- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
371 Patch by Tres Seaver.
372
Victor Stinnerde629d42010-05-05 21:43:57 +0000373- Issue #8390: tarfile uses surrogateespace as the default error handler
374 (instead of replace in read mode or strict in write mode)
375
Barry Warsaw83d89982010-05-05 16:18:31 +0000376- Issue #7755: Use an unencumbered audio file for tests.

Ronald Oussorenac764d32010-05-05 15:32:33 +0000378- Issue #8621: uuid.uuid4() returned the same sequence of values in the
379 parent and any children created using ``os.fork`` on MacOS X 10.6.
380
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000381- Issue #8567: Fix precedence of signals in Decimal module: when a
382 Decimal operation raises multiple signals and more than one of those
383 signals is trapped, the specification determines the order in which
384 the signals should be handled. In many cases this order wasn't
385 being followed, leading to the wrong Python exception being raised.
386
Antoine Pitrou6be88762010-05-03 16:48:20 +0000387- Issue #7865: The close() method of :mod:`io` objects should not swallow
388 exceptions raised by the implicit flush(). Also ensure that calling
389 close() several times is supported. Patch by Pascal Chambon.
390
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000391- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
392 gc.DEBUG_STATS.
393
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000394- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
395 webbrowser.get("safari").
396
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000397- Issue #8464: tarfile no longer creates files with execute permissions set
398 when mode="w|" is used.

Antoine Pitroubf043492010-04-29 10:11:46 +0000400- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
401 of the Linux kernel. Patch by Yaniv Aknin.
402
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000403- Issue #8295: Added shutil.unpack_archive.

Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000405- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
406 It should correctly return an empty response now.
407
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000408- Issue #8546: Reject None given as the buffering argument to _pyio.open.

Antoine Pitrou06e34a92010-04-27 19:14:15 +0000410- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
411 Sridhar Ratnakumar.
412
R. David Murrayad78d152010-04-27 02:45:53 +0000413- Issue #6656: fix locale.format_string to handle escaped percents
414 and mappings.
415
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000416- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
417 where the method could block indefinitely if called just before the
418 event loop started running. This also fixes the occasional freezes
419 witnessed in test_httpservers.
420
Antoine Pitrou40f08742010-04-24 22:04:40 +0000421- Issue #8524: When creating an SSL socket, the timeout value of the
422 original socket wasn't retained (instead, a socket with a positive timeout
423 would be turned into a non-blocking SSL socket).
424
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000425- Issue #5103: SSL handshake would ignore the socket timeout and block
426 indefinitely if the other end didn't respond.
427
428- The do_handshake() method of SSL objects now adjusts the blocking mode of
429 the SSL structure if necessary (as other methods already do).
430
Victor Stinner13bb71c2010-04-23 21:41:56 +0000431- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
432 and bytes strings for environment keys and values
433
Victor Stinner4d078042010-04-23 19:28:32 +0000434- Issue #8467: Pure Python implementation of subprocess encodes the error
435 message using surrogatepass error handler to support surrogates in the
436 message
437
Victor Stinner349fd522010-04-23 10:56:17 +0000438- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
439
Sean Reifscheider13daf122010-04-23 09:29:52 +0000440- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
441 the string "python" as the *ident*. openlog() arguments are all optional
442 and keywords.
443
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000444- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
445 a non-infinite timeout. Also make that method friendlier with applications
446 wanting to continue using the socket in clear-text mode, by disabling
447 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
448
Antoine Pitrou7062db82010-04-22 13:30:10 +0000449- Issue #8496: make mailcap.lookup() always return a list, rather than an
450 iterator. Patch by Gregory Nofi.
451
Victor Stinner35466c52010-04-22 11:23:23 +0000452- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
453 collation name contains a surrogate character.
454
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000455- Issue #8484: Load all ciphers and digest algorithms when initializing
456 the _ssl extension, such that verification of some SSL certificates
457 doesn't fail because of an "unknown algorithm".
458
Tarek Ziadéfb437512010-04-20 08:57:33 +0000459- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
460
Tarek Ziadé5340db32010-04-19 22:30:51 +0000461- Issue #1540112: Now allowing the choice of a copy function in
462 shutil.copytree.
463
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000464- Issue #4814: timeout parameter is now applied also for connections resulting
465 from PORT/EPRT commands.
466
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000467- Issue #8463: added missing reference to bztar in shutil's documentation.
468
Ronald Oussoren84151202010-04-18 20:46:11 +0000469- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
470 (as long as the user didn't specify 'automatic proxy configuration').
471
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000472- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
473 code as stated in RFC-959 at chapter 5.4.
474
Victor Stinner738446f02010-04-18 00:00:44 +0000475- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
476 surrogates.
477
Antoine Pitrou0454af92010-04-17 23:51:58 +0000478- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000479 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000480
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000481- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
482 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
483
Victor Stinner0e59cc32010-04-16 23:49:32 +0000484- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
485 the current working directory.
486
Victor Stinner5bfe1462010-04-16 13:28:05 +0000487- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
488 using backslashreplace error handler
489
Victor Stinnercfa72782010-04-16 11:45:13 +0000490- Issue #8412: os.system() now accepts bytes, bytearray and str with
491 surrogates.
492
Senthil Kumaranad02d232010-04-16 03:02:13 +0000493- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
494 Locke and Hans Ulrich Niedermann.
495
R. David Murrayd48739f2010-04-14 18:59:18 +0000496- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
497
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000498- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
499 module now takes an optional timeout argument in seconds. Timeout support
500 relies on the system threading library, so as to avoid a semi-busy wait
501 loop.
502
Victor Stinner485fb562010-04-13 11:07:24 +0000503- Issue #8383: pickle and pickletools use surrogatepass error handler when
504 encoding unicode as utf8 to support lone surrogates and stay compatible with
505 Python 2.x and 3.0
506
R. David Murrayb2416e52010-04-12 16:58:02 +0000507- Issue #7585: difflib context and unified diffs now place a tab between
508 filename and date, conforming to the 'standards' they were originally
509 designed to follow. This improves compatibility with patch tools.
510
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000511- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
512 character sets will now consistently use a Content-Transfer-Encoding of
513 7bit rather than sometimes being marked as 8bit.
514
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000515- Issue #8375: test_distutils now checks if the temporary directory are still
516 present before it cleans them.
517
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000518- Issue #8374: Update the internal alias table in the :mod:`locale` module
519 to cover recent locale changes and additions.
520
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000521- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
522 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
523 and `ssl.OPENSSL_VERSION_NUMBER`.
524
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000525- Add functools.total_ordering() and functools.cmp_to_key().
526
Mark Dickinson089b00c2010-04-03 15:51:03 +0000527- Issue #8257: The Decimal construct now accepts a float instance
528 directly, converting that float to a Decimal of equal value:
529
530 >>> Decimal(1.1)
531 Decimal('1.100000000000000088817841970012523233890533447265625')
532
Mark Dickinson98127c32010-04-03 11:18:52 +0000533- Issue #8294: The Fraction constructor now accepts Decimal and float
534 instances directly.
535
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000536- Issue #7279: Comparisons involving a Decimal signaling NaN now
537 signal InvalidOperation instead of returning False. (Comparisons
538 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
539 are now hashable; Decimal signaling NaNs remain unhashable.
540
541- Issue #2531: Comparison operations between floats and Decimal
542 instances now return a result based on the numeric values of the
543 operands; previously they returned an arbitrary result based on
544 the relative ordering of id(float) and id(Decimal).
545
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000546- Added a subtract() method to collections.Counter().
547
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000548- Issue #8233: When run as a script, py_compile.py optionally takes a single
549 argument `-` which tells it to read files to compile from stdin. Each line
550 is read on demand and the named file is compiled immediately. (Original
551 patch by Piotr Ożarowski).
552
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000553- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
554 form feed (0x0C) are now considered linebreaks, as specified in Unicode
555 Standard Annex #14. See issue #7643.
556 http://www.unicode.org/reports/tr14/
557
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000558- Comparisons using one of <, <=, >, >= between a complex instance and
559 a Fractions instance now raise TypeError instead of returning
560 True/False. This makes Fraction <=> complex comparisons consistent with
561 int <=> complex, float <=> complex, and complex <=> complex comparisons.
562
Antoine Pitrou39b35432010-03-23 00:25:54 +0000563- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
564 some methods (such as oss_mixer_device.fileno()) were not available.
565 Initial patch by Bertrand Janin.
566
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000567- Issue #8205: Remove the "Modules" directory from sys.path when Python is
568 running from the build directory (POSIX only).
569
Antoine Pitrou910bd512010-03-22 20:11:09 +0000570- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
571 didn't support chflags() (for example ZFS under FreeBSD). The error is
572 now silenced.
573
R. David Murrayca2edce2010-03-22 17:48:48 +0000574- Issue #7860: platform.uname now reports the correct 'machine' type
575 when Python is running in WOW64 mode on 64 bit Windows.
576
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000577- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
578 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
579 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000580
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000581- Issue #4282: Fix the main function of the profile module for a non-ASCII
582 script, open the file in binary mode and not in text mode with the default
583 (utf8) encoding.
584
Florent Xicluna54467e02010-03-21 12:29:50 +0000585- Issue #8179: Fix macpath.realpath() on a non-existing path.
586
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000587- Issue #8024: Update the Unicode database to 5.2.
588
Benjamin Peterson00888932010-03-18 22:37:38 +0000589- Issue #8168: py_compile now handles files with utf-8 BOMS.
590
Benjamin Peterson689a5582010-03-18 22:29:52 +0000591- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
592 detected.
593
Martin v. Löwis4b003072010-03-16 13:19:21 +0000594- Issue #6716/2: Backslash-replace error output in compilall.
595
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000596- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
597 with Tcl/Tk-8.5.
598
Matthias Klosec33b9022010-03-16 00:36:26 +0000599- Issue #8140: extend compileall to compile single files. Add -i option.
600
Matthias Klose82f60912010-03-15 13:46:04 +0000601- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
602 the locale.
603
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000604- The internals of the subprocess module on POSIX systems have been replaced
605 by an extension module (_posixsubprocess) so that the fork()+exec() can be
606 done safely without the possibility of deadlock in multithreaded applications.
607
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000608- subprocess.Popen now has restore_signals and start_new_session features.
609 The default of restore_signals=True is a new behavior compared to earlier
610 Python versions. This means that signals such as SIGPIPE are not ignored
611 by default in subprocesses launched by Python (Issue #1652).
612
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000613- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
614 cElementTree module is updated too.
615
Victor Stinnerb33062c2010-03-12 14:27:16 +0000616- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
617 an non existent program name and Python is unable to retrieve the real
618 program name
619

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

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

875 support the same flexibility as the CPython command line itself.
876
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000877- Issue #7318: multiprocessing now uses a timeout when it fails to establish

912 a modification is done through it. This fixes inconsistencies and test
913 failures on systems with slightly bogus mtime behaviour.
914
Gregory P. Smith50467882009-11-01 18:42:17 +0000915- Issue #7246 & Issue #7208: getpass now properly flushes input before
916 reading from stdin so that existing input does not confuse it and

1349
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001350- Issue #7222: Make thread "reaping" more reliable so that reference
1351 leak-chasing test runs give sensible results. The previous method of
1352 reaping threads could return successfully while some Thread objects were
1353 still referenced. This also introduces a new private function:
1354 :func:`_thread._count()`.

1358
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001359- Issue #7055: test___all__ now greedily detects all modules which have an

1364 and a new section in the summary report at the end.

1509-----------------
1510
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001511- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1512 of the command line.
1513
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001514- Issue #6012: Add cleanup support to O& argument parsing.
1515
Eric Smith41669ca2009-05-23 14:23:22 +00001516- Issue #6089: Fixed str.format with certain invalid field specifiers
1517 that would raise SystemError.
1518
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001519- Issue #5982: staticmethod and classmethod now expose the wrapped
1520 function with __func__.
1521
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001522- Added support for multiple context managers in the same with-statement.
1523 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001524
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001525- Issue #5829: complex("1e500") no longer raises OverflowError. This
1526 makes it consistent with float("1e500") and interpretation of real
1527 and imaginary literals.
1528
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001529- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1530
R. David Murraydd226ea2009-05-13 12:27:21 +00001531- Issue #5994: the marshal module now has docstrings.
1532
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001533- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1534 (1) inf and nan strings with trailing whitespace were incorrectly
1535 rejected; (2) parsing of strings representing infinities and nans
1536 was locale aware; and (3) the interpretation of fromhex('-nan')
1537 didn't match that of float('-nan').

R. David Murrayfb123912009-05-28 18:19:00 +00001544- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1545
R. David Murray1f1b9d32009-05-27 20:56:59 +00001546- Issue #6121: pydoc now ignores leading and trailing spaces in the
1547 argument to the 'help' function.
1548
Georg Brandlfaf41492009-05-26 18:31:11 +00001549- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1550 arguments for strings with a space in them.
1551
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001552- collections.namedtuple() was not working with the following field
1553 names: cls, self, tuple, itemgetter, and property.
1554
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001555- In unittest, using a skipping decorator on a class is now equivalent to
1556 skipping every test on the class. The ClassTestSuite class has been removed.
1557
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001558- Issue #6050: Don't fail extracting a directory from a zipfile if
1559 the directory already exists.
1560
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001561- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1562 than an int, which makes some operations possible under 64-bit Linux (e.g.
1563 DN_MULTISHOT with F_NOTIFY).
1564
Antoine Pitrou716c4442009-05-23 19:04:03 +00001565- Issue #5761: Add the name of the underlying file to the repr() of various
1566 IO objects.
1567
R. David Murraycaa27b72009-05-23 18:49:56 +00001568- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1569 by Musashi Tamura, tests by Marcin Bachry.
1570
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001571- Issue #1983: Fix functions taking or returning a process identifier to use
1572 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1573 a process identifier type wider than the standard C integer type.
1574
R. David Murray87e20742009-05-23 01:30:26 +00001575- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.
1576 Patch by Farhan Ahmad, test by Marcin Bachry.
1577
Antoine Pitrou6e610062009-05-15 17:04:50 +00001578- Issue #2116: Weak references and weak dictionaries now support copy()ing and
1579 deepcopy()ing.
1580
Antoine Pitrouc1d09362009-05-15 12:15:51 +00001581- Issue #1655: Make imaplib IPv6-capable. Patch by Derek Morr.
1582
Antoine Pitrou37d1c182009-05-14 21:54:00 +00001583- Issue #5918: Fix a crash in the parser module.
1584
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00001585- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
1586
Antoine Pitroue4501852009-05-14 18:55:55 +00001587- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1588 library. This means, for example, that opening an UTF-16 text file in
1589 append mode doesn't add a BOM at the end of the file if the file isn't
1590 empty.
1591
R. David Murray74b89242009-05-13 17:33:03 +00001592- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1593 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1594 corrects a pydoc regression.
1595
R. David Murray99352742009-05-07 18:24:38 +00001596- Issue 5955: aifc's close method did not close the file it wrapped,
1597 now it does. This also means getfp method now returns the real fp.
1598
Benjamin Peterson932073a2009-05-23 16:14:33 +00001599Installation
1600------------
1601
1602- Issue #6047: fullinstall has been removed because Python 3's executable will
1603 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001604
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001605- Lib/smtpd.py is no longer installed as a script.

1627-----
1628
1629- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1630 tests on darwin even when the OS was installed on a case-sensitive
1631 filesystem. Also fixed tests that should not be run when
1632 sys.dont_write_bytecode is true.

1634
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001635What's New in Python 3.1 beta 1?
1636================================
1637
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001638*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001639
1640Core and Builtins
1641-----------------
1642
Mark Dickinson865e01a2009-05-07 16:37:01 +00001643- Issue #5914: Add new C API function PyOS_string_to_double, and
1644 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1645
Eric Smith741191f2009-05-06 13:08:15 +00001646- Issue #3382: float.__format__, complex.__format__, and %-formatting
1647 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1648 affects nan -> NAN and inf -> INF.
1649
Mark Hammond5a607a32009-05-06 08:04:54 +00001650- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1651 in all operations, including splitdrive, split, etc. splitunc() now issues
1652 a PendingDeprecation warning.
1653
Eric Smith63376222009-05-05 14:04:18 +00001654- Issue #5920: For float.__format__, change the behavior with the
1655 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1656 to be like 'g' but with at least one decimal point and with a
1657 default precision of 12. Previously, the behavior the same but with
1658 a default precision of 6. This more closely matches str(), and
1659 reduces surprises when adding alignment flags to the empty
1660 presentation type. This also affects the new complex.__format__ in
1661 the same way.
1662
Martin v. Löwis011e8422009-05-05 04:43:17 +00001663- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1664
R. David Murrayb18500d2009-05-04 22:59:07 +00001665- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1666 shadowed by classtype's, even if it was None. property now
1667 inserts the __doc__ into the subclass instance __dict__.
1668
Antoine Pitrou244651a2009-05-04 18:56:13 +00001669- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1670 sequences. Patch by Nick Barnes and Victor Stinner.
1671
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001672- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001673
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001674- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1675 received a new method, detach(). detach() disconnects the underlying stream
1676 from the buffer or text IO and returns it.
1677
Mark Dickinson33841c32009-05-01 15:37:04 +00001678- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1679 floats with absolute value over 1e50. Also remove length
1680 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1681 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001682
Eric Smith741191f2009-05-06 13:08:15 +00001683- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001684 format(complex(1, 2./3), '.5') now produces a sensible result.
1685
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001686- Issue #5864: Fix empty format code formatting for floats so that it
1687 never gives more than the requested number of significant digits.
1688
Eric Smith6dc46f52009-04-27 20:39:49 +00001689- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1690 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1691
Eric Smithcc32a112009-04-26 21:35:14 +00001692- Issue #5835: Deprecate PyOS_ascii_formatd.
1693
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001694- Issue #4971: Fix titlecase for characters that are their own
1695 titlecase, but not their own uppercase.
1696
Benjamin Peterson193152c2009-04-25 01:08:45 +00001697- Issue #5283: Setting __class__ in __del__ caused a segfault.
1698
Mark Dickinsonad476da2009-04-23 19:14:16 +00001699- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1700 z involves nans, infs or negative zeros.
1701
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001702- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001703
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001704- Issue #1869 (and many duplicates): make round(x, n) correctly
1705 rounded for a float x, by using the decimal <-> binary conversions
1706 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1707 consistently agrees with format(x, '.2f').
1708
Benjamin Petersonae937c02009-04-18 20:54:08 +00001709- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1710 some builtin types.
1711
Eric Smith0923d1d2009-04-16 20:16:10 +00001712- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1713
Eric Smith35e84722009-04-16 20:21:28 +00001714- Issue #5515: str.format() type 'n' combined with commas and leading
1715 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001716
1717- Implement PEP 378, Format Specifier for Thousands Separator, for
1718 floats.
1719
Mark Dickinson3370cce2009-04-17 22:40:53 +00001720- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001721 1e11, not 1e12. This avoids printing 13 significant digits in
1722 situations where only 12 of them are correct. Example problem
1723 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1724 long time.)
1725
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001726- Issue #1580: On most platforms, use a 'short' float repr: for a
1727 finite float x, repr(x) now outputs a string based on the shortest
1728 sequence of decimal digits that rounds to x. Previous behaviour was
1729 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001730 Another minor difference is that the new repr switches to
1731 exponential notation at 1e16 instead of the previous 1e17; this
1732 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001733
1734 There's a new sys attribute sys.float_repr_style, which takes
1735 the value 'short' to indicate that we're using short float repr,
1736 and 'legacy' if the short float repr isn't available for one
1737 reason or another.
1738
1739 The float repr change involves incorporating David Gay's 'perfect
1740 rounding' code into the Python core (it's in Python/dtoa.c). As a
1741 secondary consequence, all string-to-float and float-to-string
1742 conversions (including all float formatting operations) will be
1743 correctly rounded on these platforms.
1744
1745 See issue 1580 discussions for details of platforms for which
1746 this change does not apply.
1747
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001748- Issue #5759: float() didn't call __float__ on str subclasses.
1749
Georg Brandlabc38772009-04-12 15:51:51 +00001750- The string.maketrans() function is deprecated; there is a new static method
1751 maketrans() on the bytes and bytearray classes. This removes confusion about
1752 the types string.maketrans() is supposed to work with, and mirrors the
1753 methods available on the str class.
1754
R. David Murraydc6da8a2009-04-09 22:16:43 +00001755- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1756 its clarity and its speed.
1757
Matthias Klose091c7b12009-04-07 13:24:27 +00001758- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1759 to avoid compiler warnings.
1760
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001761- Issue #3739: The unicode-internal encoder now reports the number of characters
1762 consumed like any other encoder (instead of the number of bytes).

Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002082- Issue #4935: The overflow checking code in the expandtabs() method common
2083 to str, bytes and bytearray could be optimized away by the compiler, letting
2084 the interpreter segfault instead of raising an error.
2085
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002086- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2087 __next__ method.
2088
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002089- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2090 function no longer attempt to call the __long__ slot to convert an object
2091 to an integer. Only the __int__ and __trunc__ slots are examined.
2092
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002093- Issue #4893: Use NT threading on CE.

2096
Antoine Pitrouab868312009-01-10 15:40:25 +00002097- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2098 common cases are optimized thanks to a dedicated fast path and a moderate
2099 amount of loop unrolling.
2100
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002101- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2102 collecting the oldest generation) so that allocating lots of objects without
2103 destroying them does not show quadratic performance. Based on a proposal by
2104 Martin von Löwis at
2105 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2106
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002107- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002108 having been closed (for instance, a read() call could return some
2109 previously buffered data). Patch by Dmitry Vasiliev.
2110
Antoine Pitrou05608432009-01-09 18:53:14 +00002111- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2112 flag to work properly. Furthermore, when specifying -u, the text stdout
2113 and stderr streams have line-by-line buffering enabled (the default being
2114 to buffer arbitrary chunks of data).
2115
Raymond Hettinger35631532009-01-09 03:58:09 +00002116- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2117 instead of ints (reducing its size from 4 to 8 times thereby reducing
2118 Python's overall memory).
2119
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002120- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2121 an existing .py counterpart, override the co_filename attributes of all
2122 code objects if the original filename is obsolete (which can happen if the
2123 file has been renamed, moved, or if it is accessed through different paths).
2124 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2125
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002126- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2127 one byte. Also fixes the meaning of len() so that it returns the number of
2128 items, rather than the size in bytes.
2129
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002130- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2131
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002132- Issue #4747: When the terminal does not use utf-8, executing a script with
2133 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2134
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002135- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002136 file with `bytes' filename on Windows.

Antoine Pitrou7ddda782009-01-01 15:35:33 +00002138- Issue #3680: Reference cycles created through a dict, set or deque iterator
2139 did not get collected.
2140
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002141- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2142 where the tp_hash and tp_dict slots are both NULL.
2143
Georg Brandlccc47b62008-12-28 11:44:14 +00002144- Issue #4759: None is now allowed as the first argument of
2145 bytearray.translate(). It was always allowed for bytes.translate().
2146
Skip Montanaro80072cb2008-12-23 03:51:14 +00002147- Added test case to ensure attempts to read from a file opened for writing
2148 fail.
2149
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002150- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002152- Issue #2183: Simplify and optimize bytecode for list, dict and set
2153 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2154
Antoine Pitrou621601a2008-12-17 23:18:19 +00002155- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2156 print elapsed times, not only when some objects are uncollectable /
2157 unreachable. Original patch by Neil Schemenauer.
2158
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002159- Issue #3439: Add a bit_length method to int.
2160
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002161- Issue #2173: When getting device encoding, check that return value of
2162 nl_langinfo is not the empty string. This was causing silent build
2163 failures on OS X.
2164
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002165- Issue #4597: Fixed several opcodes that weren't always propagating
2166 exceptions.
2167
2168- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002169 context manager returns a value that cannot be converted to a bool.
2170
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002171- Issue #4445: Replace "sizeof(PyBytesObject)" with
2172 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2173 bytes instances. On a typical machine this saves 3 bytes of memory
2174 (on average) per allocation of a bytes instance.
2175
Christian Heimesa872de52008-12-05 08:26:55 +00002176- Issue #4533: File read operation was dreadfully slow due to a slowly
2177 growing read buffer. Fixed by using the same growth rate algorithm as
2178 Python 2.x.
2179
Antoine Pitrou5504e892008-12-06 21:27:53 +00002180- Issue #4509: Various issues surrounding resize of bytearray objects to
2181 which there are buffer exports (e.g. memoryview instances).
2182
Georg Brandlf9734072008-12-07 15:30:06 +00002183- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2184 method on file objects with closefd=False. The file descriptor is still
2185 kept open but the file object behaves like a closed file. The ``FileIO``
2186 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002187
Antoine Pitroubc420402008-12-07 20:14:49 +00002188- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2189 larger than 1.

2194
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002195- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2196 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2197 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2198 of using the replace error handler in PyUnicode_DecodeUTF8().
