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.

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

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.

Antoine Pitrou53b21662010-05-11 23:46:02 +0000354- Issue #8681: Make the zlib module's error messages more informative when
355 the zlib itself doesn't give any detailed explanation.
356
Mark Dickinson81fece22010-05-11 13:34:35 +0000357- The audioop module now supports sound fragments of length greater
358 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
359
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000360- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
361 class.
362
Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000363- Issue #8664: In py_compile, create __pycache__ when the compiled path is
364 given.
365
Victor Stinner449c4662010-05-08 11:10:09 +0000366- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
367 for use in the file system, environment variables or the command line.
368
Antoine Pitrou89562712010-05-07 17:04:02 +0000369- Issue #8571: Fix an internal error when compressing or decompressing a

371 objects.
372
Benjamin Peterson225168e2010-05-06 22:29:53 +0000373- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
374 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
375 file system encoding with the surrogateescape error handler (instead of
376 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000378- Issue #8573: asyncore _strerror() function might throw ValueError.
379
380- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
381 error messages when accessing undefined class attributes because of the cheap
382 inheritance with the underlying socket object.
383 The cheap inheritance has been deprecated.
384
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000385- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
386 Patch by Tres Seaver.
387
Victor Stinnerde629d42010-05-05 21:43:57 +0000388- Issue #8390: tarfile uses surrogateespace as the default error handler

395
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000396- Issue #8567: Fix precedence of signals in Decimal module: when a
397 Decimal operation raises multiple signals and more than one of those
398 signals is trapped, the specification determines the order in which
399 the signals should be handled. In many cases this order wasn't
400 being followed, leading to the wrong Python exception being raised.
401
Antoine Pitrou6be88762010-05-03 16:48:20 +0000402- Issue #7865: The close() method of :mod:`io` objects should not swallow
403 exceptions raised by the implicit flush(). Also ensure that calling
404 close() several times is supported. Patch by Pascal Chambon.
405
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000406- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
407 gc.DEBUG_STATS.
408
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000409- Issue #8354: The siginterrupt setting is now preserved for all signals,
410 not just SIGCHLD.
411
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000412- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
413 webbrowser.get("safari").
414
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000415- Issue #8464: tarfile no longer creates files with execute permissions set
416 when mode="w|" is used.
417
Antoine Pitroubf043492010-04-29 10:11:46 +0000418- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
419 of the Linux kernel. Patch by Yaniv Aknin.

422
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000423- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
424 It should correctly return an empty response now.
425
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000426- Issue #8546: Reject None given as the buffering argument to _pyio.open.

R. David Murrayad78d152010-04-27 02:45:53 +0000431- Issue #6656: fix locale.format_string to handle escaped percents
432 and mappings.
433
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000434- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
435 where the method could block indefinitely if called just before the
436 event loop started running. This also fixes the occasional freezes
437 witnessed in test_httpservers.
438
Antoine Pitrou40f08742010-04-24 22:04:40 +0000439- Issue #8524: When creating an SSL socket, the timeout value of the
440 original socket wasn't retained (instead, a socket with a positive timeout
441 would be turned into a non-blocking SSL socket).
442
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000443- Issue #5103: SSL handshake would ignore the socket timeout and block
444 indefinitely if the other end didn't respond.
445
446- The do_handshake() method of SSL objects now adjusts the blocking mode of
447 the SSL structure if necessary (as other methods already do).
448
Victor Stinner13bb71c2010-04-23 21:41:56 +0000449- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
450 and bytes strings for environment keys and values
451
Victor Stinner4d078042010-04-23 19:28:32 +0000452- Issue #8467: Pure Python implementation of subprocess encodes the error

457
Sean Reifscheider13daf122010-04-23 09:29:52 +0000458- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
459 the string "python" as the *ident*. openlog() arguments are all optional
460 and keywords.
461
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000462- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
463 a non-infinite timeout. Also make that method friendlier with applications
464 wanting to continue using the socket in clear-text mode, by disabling
465 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
466
Antoine Pitrou7062db82010-04-22 13:30:10 +0000467- Issue #8496: make mailcap.lookup() always return a list, rather than an
468 iterator. Patch by Gregory Nofi.

Antoine Pitroufec12ff2010-04-21 19:46:23 +0000473- Issue #8484: Load all ciphers and digest algorithms when initializing
474 the _ssl extension, such that verification of some SSL certificates
475 doesn't fail because of an "unknown algorithm".
476
Tarek Ziadéfb437512010-04-20 08:57:33 +0000477- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
478
Tarek Ziadé5340db32010-04-19 22:30:51 +0000479- Issue #1540112: Now allowing the choice of a copy function in
480 shutil.copytree.
481
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000482- Issue #4814: timeout parameter is now applied also for connections resulting
483 from PORT/EPRT commands.
484
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000485- Issue #8463: added missing reference to bztar in shutil's documentation.
486
Ronald Oussoren84151202010-04-18 20:46:11 +0000487- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
488 (as long as the user didn't specify 'automatic proxy configuration').
489
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000490- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
491 code as stated in RFC-959 at chapter 5.4.
492
Victor Stinner738446f02010-04-18 00:00:44 +0000493- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
494 surrogates.
495
Antoine Pitrou0454af92010-04-17 23:51:58 +0000496- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000497 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000499- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
500 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
501
Victor Stinner0e59cc32010-04-16 23:49:32 +0000502- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
503 the current working directory.
504
Victor Stinner5bfe1462010-04-16 13:28:05 +0000505- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
506 using backslashreplace error handler

515
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000516- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
517 module now takes an optional timeout argument in seconds. Timeout support
518 relies on the system threading library, so as to avoid a semi-busy wait
519 loop.
520
Victor Stinner485fb562010-04-13 11:07:24 +0000521- Issue #8383: pickle and pickletools use surrogatepass error handler when

523 Python 2.x and 3.0
524
R. David Murrayb2416e52010-04-12 16:58:02 +0000525- Issue #7585: difflib context and unified diffs now place a tab between
526 filename and date, conforming to the 'standards' they were originally
527 designed to follow. This improves compatibility with patch tools.
528
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000529- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
530 character sets will now consistently use a Content-Transfer-Encoding of
531 7bit rather than sometimes being marked as 8bit.
532
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000533- Issue #8375: test_distutils now checks if the temporary directory are still
534 present before it cleans them.
535
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000536- Issue #8374: Update the internal alias table in the :mod:`locale` module
537 to cover recent locale changes and additions.
538
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000539- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
540 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
541 and `ssl.OPENSSL_VERSION_NUMBER`.
542
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000543- Add functools.total_ordering() and functools.cmp_to_key().
544
Mark Dickinson089b00c2010-04-03 15:51:03 +0000545- Issue #8257: The Decimal construct now accepts a float instance
546 directly, converting that float to a Decimal of equal value:
547
548 >>> Decimal(1.1)
549 Decimal('1.100000000000000088817841970012523233890533447265625')
550
Mark Dickinson98127c32010-04-03 11:18:52 +0000551- Issue #8294: The Fraction constructor now accepts Decimal and float
552 instances directly.
553
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000554- Issue #7279: Comparisons involving a Decimal signaling NaN now
555 signal InvalidOperation instead of returning False. (Comparisons
556 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
557 are now hashable; Decimal signaling NaNs remain unhashable.
558
559- Issue #2531: Comparison operations between floats and Decimal
560 instances now return a result based on the numeric values of the
561 operands; previously they returned an arbitrary result based on
562 the relative ordering of id(float) and id(Decimal).
563
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000564- Added a subtract() method to collections.Counter().
565
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000566- Issue #8233: When run as a script, py_compile.py optionally takes a single
567 argument `-` which tells it to read files to compile from stdin. Each line
568 is read on demand and the named file is compiled immediately. (Original
569 patch by Piotr Ożarowski).
570
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000571- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
572 form feed (0x0C) are now considered linebreaks, as specified in Unicode
573 Standard Annex #14. See issue #7643.
574 http://www.unicode.org/reports/tr14/
575
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000576- Comparisons using one of <, <=, >, >= between a complex instance and
577 a Fractions instance now raise TypeError instead of returning
578 True/False. This makes Fraction <=> complex comparisons consistent with
579 int <=> complex, float <=> complex, and complex <=> complex comparisons.
580
Antoine Pitrou39b35432010-03-23 00:25:54 +0000581- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

590 now silenced.
591
R. David Murrayca2edce2010-03-22 17:48:48 +0000592- Issue #7860: platform.uname now reports the correct 'machine' type
593 when Python is running in WOW64 mode on 64 bit Windows.
594
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000595- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
596 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
597 reads and writes are always retried by OpenSSL itself.

Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000622- The internals of the subprocess module on POSIX systems have been replaced
623 by an extension module (_posixsubprocess) so that the fork()+exec() can be
624 done safely without the possibility of deadlock in multithreaded applications.
625
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000626- subprocess.Popen now has restore_signals and start_new_session features.
627 The default of restore_signals=True is a new behavior compared to earlier
628 Python versions. This means that signals such as SIGPIPE are not ignored
629 by default in subprocesses launched by Python (Issue #1652).

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

717 file position when calling `truncate()`. It would previously change the
718 file position to the given argument, which goes against the tradition of
719 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
720
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000721- Issue #7610: Reworked implementation of the internal
722 :class:`zipfile.ZipExtFile` class used to represent files stored inside
723 an archive. The new implementation is significantly faster and can
724 be wrapped in a :class:`io.BufferedReader` object for more speedups.
725 It also solves an issue where interleaved calls to `read()` and
726 `readline()` give wrong results. Patch by Nir Aides.

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

893 support the same flexibility as the CPython command line itself.

1381 leak-chasing test runs give sensible results. The previous method of
1382 reaping threads could return successfully while some Thread objects were
1383 still referenced. This also introduces a new private function:
1384 :func:`_thread._count()`.
1385
R. David Murray27144602009-10-19 15:26:16 +00001386- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1387 longer runs the risk of causing the worker thread to fail.
1388
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001389- Issue #7055: test___all__ now greedily detects all modules which have an

1394 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001395
Mark Dickinson2e304402009-10-04 18:43:54 +00001396- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1397
Brett Cannon3c273842009-07-20 00:14:29 +00001398- Fixed tests in importlib.test.source.test_abc_loader that were masking
1399 the proper exceptions that should be raised for missing or improper code
1400 object bytecode.
1401
Brett Cannonb49c70c2009-07-15 04:08:33 +00001402- Removed importlib's custom test discovery code and switched to

1490 or dumping pickles with a 2.x-compatible protocol, in order to make data
1491 sharing and migration easier. This behaviour can be disabled using the
1492 new `fix_imports` optional argument.

Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001541- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1542 of the command line.
1543
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001544- Issue #6012: Add cleanup support to O& argument parsing.
1545
Eric Smith41669ca2009-05-23 14:23:22 +00001546- Issue #6089: Fixed str.format with certain invalid field specifiers
1547 that would raise SystemError.
1548
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001549- Issue #5982: staticmethod and classmethod now expose the wrapped
1550 function with __func__.
1551
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001552- Added support for multiple context managers in the same with-statement.
1553 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001555- Issue #5829: complex("1e500") no longer raises OverflowError. This
1556 makes it consistent with float("1e500") and interpretation of real
1557 and imaginary literals.
1558
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001559- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1560
R. David Murraydd226ea2009-05-13 12:27:21 +00001561- Issue #5994: the marshal module now has docstrings.
1562
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001563- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1564 (1) inf and nan strings with trailing whitespace were incorrectly
1565 rejected; (2) parsing of strings representing infinities and nans
1566 was locale aware; and (3) the interpretation of fromhex('-nan')
1567 didn't match that of float('-nan').

Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001572- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1573
R. David Murrayfb123912009-05-28 18:19:00 +00001574- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1575
R. David Murray1f1b9d32009-05-27 20:56:59 +00001576- Issue #6121: pydoc now ignores leading and trailing spaces in the
1577 argument to the 'help' function.
1578
Georg Brandlfaf41492009-05-26 18:31:11 +00001579- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1580 arguments for strings with a space in them.
1581
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001582- collections.namedtuple() was not working with the following field
1583 names: cls, self, tuple, itemgetter, and property.
1584
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001585- In unittest, using a skipping decorator on a class is now equivalent to
1586 skipping every test on the class. The ClassTestSuite class has been removed.
1587
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001588- Issue #6050: Don't fail extracting a directory from a zipfile if
1589 the directory already exists.
1590
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001591- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1592 than an int, which makes some operations possible under 64-bit Linux (e.g.
1593 DN_MULTISHOT with F_NOTIFY).
1594
Antoine Pitrou716c4442009-05-23 19:04:03 +00001595- Issue #5761: Add the name of the underlying file to the repr() of various

1599 by Musashi Tamura, tests by Marcin Bachry.
1600
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001601- Issue #1983: Fix functions taking or returning a process identifier to use
1602 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1603 a process identifier type wider than the standard C integer type.
1604
R. David Murray87e20742009-05-23 01:30:26 +00001605- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1616
Antoine Pitroue4501852009-05-14 18:55:55 +00001617- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1618 library. This means, for example, that opening an UTF-16 text file in
1619 append mode doesn't add a BOM at the end of the file if the file isn't
1620 empty.
1621
R. David Murray74b89242009-05-13 17:33:03 +00001622- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1623 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1624 corrects a pydoc regression.
1625
R. David Murray99352742009-05-07 18:24:38 +00001626- Issue 5955: aifc's close method did not close the file it wrapped,
1627 now it does. This also means getfp method now returns the real fp.

1670Core and Builtins
1671-----------------
1672
Mark Dickinson865e01a2009-05-07 16:37:01 +00001673- Issue #5914: Add new C API function PyOS_string_to_double, and
1674 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1675
Eric Smith741191f2009-05-06 13:08:15 +00001676- Issue #3382: float.__format__, complex.__format__, and %-formatting
1677 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1678 affects nan -> NAN and inf -> INF.
1679
Mark Hammond5a607a32009-05-06 08:04:54 +00001680- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1681 in all operations, including splitdrive, split, etc. splitunc() now issues
1682 a PendingDeprecation warning.
1683
Eric Smith63376222009-05-05 14:04:18 +00001684- Issue #5920: For float.__format__, change the behavior with the
1685 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1686 to be like 'g' but with at least one decimal point and with a
1687 default precision of 12. Previously, the behavior the same but with
1688 a default precision of 6. This more closely matches str(), and
1689 reduces surprises when adding alignment flags to the empty
1690 presentation type. This also affects the new complex.__format__ in
1691 the same way.
1692
Martin v. Löwis011e8422009-05-05 04:43:17 +00001693- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1694
R. David Murrayb18500d2009-05-04 22:59:07 +00001695- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1696 shadowed by classtype's, even if it was None. property now
1697 inserts the __doc__ into the subclass instance __dict__.
1698
Antoine Pitrou244651a2009-05-04 18:56:13 +00001699- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1700 sequences. Patch by Nick Barnes and Victor Stinner.
1701
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001702- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001703
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001704- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1705 received a new method, detach(). detach() disconnects the underlying stream
1706 from the buffer or text IO and returns it.
1707
Mark Dickinson33841c32009-05-01 15:37:04 +00001708- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1709 floats with absolute value over 1e50. Also remove length
1710 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1711 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001712
Eric Smith741191f2009-05-06 13:08:15 +00001713- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001714 format(complex(1, 2./3), '.5') now produces a sensible result.
1715
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001716- Issue #5864: Fix empty format code formatting for floats so that it
1717 never gives more than the requested number of significant digits.
1718
Eric Smith6dc46f52009-04-27 20:39:49 +00001719- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1720 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1721
Eric Smithcc32a112009-04-26 21:35:14 +00001722- Issue #5835: Deprecate PyOS_ascii_formatd.
1723
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001724- Issue #4971: Fix titlecase for characters that are their own
1725 titlecase, but not their own uppercase.
1726
Benjamin Peterson193152c2009-04-25 01:08:45 +00001727- Issue #5283: Setting __class__ in __del__ caused a segfault.
1728
Mark Dickinsonad476da2009-04-23 19:14:16 +00001729- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1730 z involves nans, infs or negative zeros.
1731
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001732- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001733
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001734- Issue #1869 (and many duplicates): make round(x, n) correctly
1735 rounded for a float x, by using the decimal <-> binary conversions
1736 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1737 consistently agrees with format(x, '.2f').
1738
Benjamin Petersonae937c02009-04-18 20:54:08 +00001739- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1740 some builtin types.
1741
Eric Smith0923d1d2009-04-16 20:16:10 +00001742- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1743
Eric Smith35e84722009-04-16 20:21:28 +00001744- Issue #5515: str.format() type 'n' combined with commas and leading
1745 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001746
1747- Implement PEP 378, Format Specifier for Thousands Separator, for
1748 floats.
1749
Mark Dickinson3370cce2009-04-17 22:40:53 +00001750- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001751 1e11, not 1e12. This avoids printing 13 significant digits in
1752 situations where only 12 of them are correct. Example problem
1753 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1754 long time.)
1755
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001756- Issue #1580: On most platforms, use a 'short' float repr: for a
1757 finite float x, repr(x) now outputs a string based on the shortest
1758 sequence of decimal digits that rounds to x. Previous behaviour was
1759 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001760 Another minor difference is that the new repr switches to
1761 exponential notation at 1e16 instead of the previous 1e17; this
1762 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001763
1764 There's a new sys attribute sys.float_repr_style, which takes
1765 the value 'short' to indicate that we're using short float repr,
1766 and 'legacy' if the short float repr isn't available for one
1767 reason or another.
1768
1769 The float repr change involves incorporating David Gay's 'perfect
1770 rounding' code into the Python core (it's in Python/dtoa.c). As a
1771 secondary consequence, all string-to-float and float-to-string
1772 conversions (including all float formatting operations) will be
1773 correctly rounded on these platforms.
1774
1775 See issue 1580 discussions for details of platforms for which
1776 this change does not apply.
1777
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001778- Issue #5759: float() didn't call __float__ on str subclasses.
1779
Georg Brandlabc38772009-04-12 15:51:51 +00001780- The string.maketrans() function is deprecated; there is a new static method
1781 maketrans() on the bytes and bytearray classes. This removes confusion about
1782 the types string.maketrans() is supposed to work with, and mirrors the
1783 methods available on the str class.
1784
R. David Murraydc6da8a2009-04-09 22:16:43 +00001785- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Mark Dickinsone94c6792009-02-02 20:36:42 +00002085 the type definition cmpfunc. The tp_compare slot has been renamed
2086 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002088- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002089 were suppressing all exceptions. These include list() and bytearray().
2090
Mark Dickinson1124e712009-01-28 21:25:58 +00002091- Issue #4707: round(x, n) now returns an integer if x is an integer.
2092 Previously it returned a float.
2093
Antoine Pitroub52ec782009-01-25 16:34:23 +00002094- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2095 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2096 evaluation loop is compiled with a new dispatch mechanism which gives
2097 speedups of up to 20%, depending on the system, on various benchmarks.
2098
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002099- Issue #4874: Most builtin decoders now reject unicode input.

2102 from a string.
2103
Benjamin Peterson05e782f2009-01-19 15:15:02 +00002104- Issue #4991: os.fdopen now raises an OSError for invalid file descriptors.
2105
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002106- Issue #4838: When a module is deallocated, free the memory backing the
2107 optional module state data.
2108
Mark Dickinson8055afd2009-01-17 10:04:45 +00002109- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2110 type to (void *).
2111
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002112- Issue #4935: The overflow checking code in the expandtabs() method common
2113 to str, bytes and bytearray could be optimized away by the compiler, letting
2114 the interpreter segfault instead of raising an error.
2115
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002116- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2117 __next__ method.
2118
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002119- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2120 function no longer attempt to call the __long__ slot to convert an object
2121 to an integer. Only the __int__ and __trunc__ slots are examined.

2126
Antoine Pitrouab868312009-01-10 15:40:25 +00002127- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2128 common cases are optimized thanks to a dedicated fast path and a moderate
2129 amount of loop unrolling.
2130
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002131- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2132 collecting the oldest generation) so that allocating lots of objects without
2133 destroying them does not show quadratic performance. Based on a proposal by
2134 Martin von Löwis at
2135 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2136
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002137- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002138 having been closed (for instance, a read() call could return some
2139 previously buffered data). Patch by Dmitry Vasiliev.
2140
Antoine Pitrou05608432009-01-09 18:53:14 +00002141- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2142 flag to work properly. Furthermore, when specifying -u, the text stdout
2143 and stderr streams have line-by-line buffering enabled (the default being
2144 to buffer arbitrary chunks of data).
2145
Raymond Hettinger35631532009-01-09 03:58:09 +00002146- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2147 instead of ints (reducing its size from 4 to 8 times thereby reducing
2148 Python's overall memory).
2149
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002150- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2151 an existing .py counterpart, override the co_filename attributes of all
2152 code objects if the original filename is obsolete (which can happen if the
2153 file has been renamed, moved, or if it is accessed through different paths).
2154 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2155
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002156- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2157 one byte. Also fixes the meaning of len() so that it returns the number of
2158 items, rather than the size in bytes.
2159
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002160- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2161
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002162- Issue #4747: When the terminal does not use utf-8, executing a script with
2163 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2164
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002165- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002166 file with `bytes' filename on Windows.

2169 did not get collected.
2170
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002171- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2172 where the tp_hash and tp_dict slots are both NULL.
2173
Georg Brandlccc47b62008-12-28 11:44:14 +00002174- Issue #4759: None is now allowed as the first argument of
2175 bytearray.translate(). It was always allowed for bytes.translate().
2176
Skip Montanaro80072cb2008-12-23 03:51:14 +00002177- Added test case to ensure attempts to read from a file opened for writing
2178 fail.
2179
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002180- Issue #3106: Speedup some comparisons (str/str and int/int).

2184
Antoine Pitrou621601a2008-12-17 23:18:19 +00002185- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2187 unreachable. Original patch by Neil Schemenauer.
2188

2190
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002191- Issue #2173: When getting device encoding, check that return value of
2192 nl_langinfo is not the empty string. This was causing silent build
2193 failures on OS X.
2194
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002195- Issue #4597: Fixed several opcodes that weren't always propagating
2196 exceptions.
2197
2198- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002199 context manager returns a value that cannot be converted to a bool.
2200
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002201- Issue #4445: Replace "sizeof(PyBytesObject)" with
2202 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2203 bytes instances. On a typical machine this saves 3 bytes of memory
2204 (on average) per allocation of a bytes instance.
2205
Christian Heimesa872de52008-12-05 08:26:55 +00002206- Issue #4533: File read operation was dreadfully slow due to a slowly
2207 growing read buffer. Fixed by using the same growth rate algorithm as
2208 Python 2.x.
2209
Antoine Pitrou5504e892008-12-06 21:27:53 +00002210- Issue #4509: Various issues surrounding resize of bytearray objects to
2211 which there are buffer exports (e.g. memoryview instances).
2212
Georg Brandlf9734072008-12-07 15:30:06 +00002213- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2214 method on file objects with closefd=False. The file descriptor is still
2215 kept open but the file object behaves like a closed file. The ``FileIO``
2216 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002218- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2224
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002225- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2226 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2227 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2228 of using the replace error handler in PyUnicode_DecodeUTF8().
