111 deprecations.
112
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000113- Issue #7385: Fix a crash in `MemoryView_FromObject` when
114 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
115
Mark Dickinsonbc099642010-01-29 17:27:24 +0000116- Issue #7788: Fix an interpreter crash produced by deleting a list
117 slice with very large step value.
118
Eric Smithf7bb5782010-01-27 00:44:57 +0000119- Issue #7766: Change sys.getwindowsversion() return value to a named
120 tuple and add the additional members returned in an OSVERSIONINFOEX

123
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000124- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
125 could crash in many places because of the PyByteArray_AS_STRING() macro
126 returning NULL. The macro now returns a statically allocated empty
127 string instead.
128
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000129- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
130 where the right hand operand is a set of constants, by turning the set into
131 a frozenset and pre-building it as a constant. The comparison operation
132 is made against the constant instead of building a new set each time it is
133 executed (a similar optimization already existed which turned a list of
134 constants into a pre-built tuple). Patch and additional tests by Dave
135 Malcolm.
136
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000137- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

142 alpha 2, including: (1) a serious 'wrong output' bug that could
143 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
144 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000145 strings corresponding to subnormal values, (3) a memory leak for
146 some values large enough to cause overflow, and (4) a number of
147 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000148
Benjamin Petersonaea44282010-01-04 01:10:28 +0000149- The __complex__ method is now looked up on the class of instances to make it

160 described in C99 Annex F.
161
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000162- Issue #1811: improve accuracy and cross-platform consistency for
163 true division of integers: the result of a/b is now correctly
164 rounded for ints a and b (at least on IEEE 754 platforms), and in
165 particular does not depend on the internal representation of an int.
166
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000167- Issue #6834: replace the implementation for the 'python' and 'pythonw'
168 executables on OSX.
169

192 over range(a, b, c) incorrectly gave an empty iterator when a, b and
193 c fit in C long but the length of the range did not. Also fix
194 several cases where reversed(range(a, b, c)) gave wrong results, and
195 fix a refleak for reversed(range(a, b, c)) with large arguments.

311 function declaration, which was kept for backwards compatibility reasons,
312 is now removed (the macro was introduced in 1997!).
313
Mark Dickinson93f562c2010-01-30 10:30:15 +0000314- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
315 analogous to PyLong_AsLongAndOverflow.
316
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000317- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
318 has '\0' at the end.
319
Mark Dickinsonde604012010-01-01 19:27:32 +0000320- Issue #5080: The argument parsing functions PyArg_ParseTuple,
321 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
322 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
323 DeprecationWarning for float arguments passed with the 'L' format
324 code. This will become a TypeError in a future version of Python,
325 to match the behaviour of the other integer format codes.
326
Georg Brandl1e28a272009-12-28 08:41:01 +0000327- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
328
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000329- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
330 in PyArg_ParseTupleAndKeywords.
331
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000332- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)
Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000333 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
334
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000335- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
336 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
337 should used for accessing the d_type and d_name members of structures
338 using PyDescr_COMMON.
339
340- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000341

343
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000344- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
345 PyCode_Addr2Line().
346
347- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
348 object at a specified file, function, and line number.
349
350- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
351 ``const char *`` as the string is stored beyond the call.
352
Benjamin Peterson05159c42009-12-03 03:01:27 +0000353- Issue #2422: When compiled with the ``--with-valgrind`` option, the
354 pymalloc allocator will be automatically disabled when running under
355 Valgrind. This gives improved memory leak detection when running
356 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou53b21662010-05-11 23:46:02 +0000361- Issue #8681: Make the zlib module's error messages more informative when
362 the zlib itself doesn't give any detailed explanation.
363
Mark Dickinson81fece22010-05-11 13:34:35 +0000364- The audioop module now supports sound fragments of length greater
365 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
366
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000367- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
368 class.
369
Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000370- Issue #8664: In py_compile, create __pycache__ when the compiled path is
371 given.
372
Victor Stinner449c4662010-05-08 11:10:09 +0000373- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
374 for use in the file system, environment variables or the command line.
375
Antoine Pitrou89562712010-05-07 17:04:02 +0000376- Issue #8571: Fix an internal error when compressing or decompressing a
377 chunk larger than 1GB with the zlib module's compressor and decompressor
378 objects.
379
Benjamin Peterson225168e2010-05-06 22:29:53 +0000380- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
381 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
382 file system encoding with the surrogateescape error handler (instead of
383 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000385- Issue #8573: asyncore _strerror() function might throw ValueError.
386
387- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
388 error messages when accessing undefined class attributes because of the cheap
389 inheritance with the underlying socket object.
390 The cheap inheritance has been deprecated.
391
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000392- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
393 Patch by Tres Seaver.
394
Victor Stinnerde629d42010-05-05 21:43:57 +0000395- Issue #8390: tarfile uses surrogateespace as the default error handler
396 (instead of replace in read mode or strict in write mode)
397
Barry Warsaw83d89982010-05-05 16:18:31 +0000398- Issue #7755: Use an unencumbered audio file for tests.
399
Ronald Oussorenac764d32010-05-05 15:32:33 +0000400- Issue #8621: uuid.uuid4() returned the same sequence of values in the
401 parent and any children created using ``os.fork`` on MacOS X 10.6.
402
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000403- Issue #8567: Fix precedence of signals in Decimal module: when a
404 Decimal operation raises multiple signals and more than one of those
405 signals is trapped, the specification determines the order in which
406 the signals should be handled. In many cases this order wasn't
407 being followed, leading to the wrong Python exception being raised.
408
Antoine Pitrou6be88762010-05-03 16:48:20 +0000409- Issue #7865: The close() method of :mod:`io` objects should not swallow
410 exceptions raised by the implicit flush(). Also ensure that calling
411 close() several times is supported. Patch by Pascal Chambon.
412
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000413- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
414 gc.DEBUG_STATS.
415
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000416- Issue #8354: The siginterrupt setting is now preserved for all signals,
417 not just SIGCHLD.
418
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000419- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
420 webbrowser.get("safari").
421
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000422- Issue #8464: tarfile no longer creates files with execute permissions set
423 when mode="w|" is used.
424
Antoine Pitroubf043492010-04-29 10:11:46 +0000425- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
426 of the Linux kernel. Patch by Yaniv Aknin.
427
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000428- Issue #8295: Added shutil.unpack_archive.
429
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000430- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
431 It should correctly return an empty response now.
432
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000433- Issue #8546: Reject None given as the buffering argument to _pyio.open.
434
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000435- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
436 Sridhar Ratnakumar.
437
R. David Murrayad78d152010-04-27 02:45:53 +0000438- Issue #6656: fix locale.format_string to handle escaped percents
439 and mappings.
440
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000441- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
442 where the method could block indefinitely if called just before the
443 event loop started running. This also fixes the occasional freezes
444 witnessed in test_httpservers.
445
Antoine Pitrou40f08742010-04-24 22:04:40 +0000446- Issue #8524: When creating an SSL socket, the timeout value of the
447 original socket wasn't retained (instead, a socket with a positive timeout
448 would be turned into a non-blocking SSL socket).
449
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000450- Issue #5103: SSL handshake would ignore the socket timeout and block
451 indefinitely if the other end didn't respond.
452
453- The do_handshake() method of SSL objects now adjusts the blocking mode of
454 the SSL structure if necessary (as other methods already do).
455
Victor Stinner13bb71c2010-04-23 21:41:56 +0000456- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
457 and bytes strings for environment keys and values
458
Victor Stinner4d078042010-04-23 19:28:32 +0000459- Issue #8467: Pure Python implementation of subprocess encodes the error
460 message using surrogatepass error handler to support surrogates in the
461 message
462
Victor Stinner349fd522010-04-23 10:56:17 +0000463- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
464
Sean Reifscheider13daf122010-04-23 09:29:52 +0000465- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
466 the string "python" as the *ident*. openlog() arguments are all optional
467 and keywords.
468
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000469- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
470 a non-infinite timeout. Also make that method friendlier with applications
471 wanting to continue using the socket in clear-text mode, by disabling
472 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
473
Antoine Pitrou7062db82010-04-22 13:30:10 +0000474- Issue #8496: make mailcap.lookup() always return a list, rather than an
475 iterator. Patch by Gregory Nofi.
476
Victor Stinner35466c52010-04-22 11:23:23 +0000477- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
478 collation name contains a surrogate character.
479
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000480- Issue #8484: Load all ciphers and digest algorithms when initializing
481 the _ssl extension, such that verification of some SSL certificates
482 doesn't fail because of an "unknown algorithm".
483
Tarek Ziadéfb437512010-04-20 08:57:33 +0000484- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
485
Tarek Ziadé5340db32010-04-19 22:30:51 +0000486- Issue #1540112: Now allowing the choice of a copy function in
487 shutil.copytree.
488
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000489- Issue #4814: timeout parameter is now applied also for connections resulting
490 from PORT/EPRT commands.
491
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000492- Issue #8463: added missing reference to bztar in shutil's documentation.
493
Ronald Oussoren84151202010-04-18 20:46:11 +0000494- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
495 (as long as the user didn't specify 'automatic proxy configuration').
496
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000497- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
498 code as stated in RFC-959 at chapter 5.4.
499
Victor Stinner738446f02010-04-18 00:00:44 +0000500- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
501 surrogates.
502
Antoine Pitrou0454af92010-04-17 23:51:58 +0000503- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000504 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000505
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000506- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
507 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
508
Victor Stinner0e59cc32010-04-16 23:49:32 +0000509- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
510 the current working directory.
511
Victor Stinner5bfe1462010-04-16 13:28:05 +0000512- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
513 using backslashreplace error handler
514
Victor Stinnercfa72782010-04-16 11:45:13 +0000515- Issue #8412: os.system() now accepts bytes, bytearray and str with
516 surrogates.
517
Senthil Kumaranad02d232010-04-16 03:02:13 +0000518- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony

R. David Murrayd48739f2010-04-14 18:59:18 +0000521- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
522
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000523- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
524 module now takes an optional timeout argument in seconds. Timeout support
525 relies on the system threading library, so as to avoid a semi-busy wait
526 loop.
527
Victor Stinner485fb562010-04-13 11:07:24 +0000528- Issue #8383: pickle and pickletools use surrogatepass error handler when
529 encoding unicode as utf8 to support lone surrogates and stay compatible with
530 Python 2.x and 3.0
531
R. David Murrayb2416e52010-04-12 16:58:02 +0000532- Issue #7585: difflib context and unified diffs now place a tab between
533 filename and date, conforming to the 'standards' they were originally
534 designed to follow. This improves compatibility with patch tools.
535
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000536- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
537 character sets will now consistently use a Content-Transfer-Encoding of
538 7bit rather than sometimes being marked as 8bit.
539
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000540- Issue #8375: test_distutils now checks if the temporary directory are still
541 present before it cleans them.
542
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000543- Issue #8374: Update the internal alias table in the :mod:`locale` module
544 to cover recent locale changes and additions.
545
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000546- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
547 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
548 and `ssl.OPENSSL_VERSION_NUMBER`.
549
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000550- Add functools.total_ordering() and functools.cmp_to_key().
551
Mark Dickinson089b00c2010-04-03 15:51:03 +0000552- Issue #8257: The Decimal construct now accepts a float instance
553 directly, converting that float to a Decimal of equal value:
554
555 >>> Decimal(1.1)
556 Decimal('1.100000000000000088817841970012523233890533447265625')
557
Mark Dickinson98127c32010-04-03 11:18:52 +0000558- Issue #8294: The Fraction constructor now accepts Decimal and float
559 instances directly.
560
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000561- Issue #7279: Comparisons involving a Decimal signaling NaN now
562 signal InvalidOperation instead of returning False. (Comparisons
563 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
564 are now hashable; Decimal signaling NaNs remain unhashable.
565
566- Issue #2531: Comparison operations between floats and Decimal
567 instances now return a result based on the numeric values of the
568 operands; previously they returned an arbitrary result based on
569 the relative ordering of id(float) and id(Decimal).
570
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000571- Added a subtract() method to collections.Counter().
572
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000573- Issue #8233: When run as a script, py_compile.py optionally takes a single
574 argument `-` which tells it to read files to compile from stdin. Each line
575 is read on demand and the named file is compiled immediately. (Original
576 patch by Piotr Ożarowski).
577
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000578- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
579 form feed (0x0C) are now considered linebreaks, as specified in Unicode
580 Standard Annex #14. See issue #7643.
581 http://www.unicode.org/reports/tr14/
582
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000583- Comparisons using one of <, <=, >, >= between a complex instance and
584 a Fractions instance now raise TypeError instead of returning
585 True/False. This makes Fraction <=> complex comparisons consistent with
586 int <=> complex, float <=> complex, and complex <=> complex comparisons.
587
Antoine Pitrou39b35432010-03-23 00:25:54 +0000588- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

597 now silenced.
598
R. David Murrayca2edce2010-03-22 17:48:48 +0000599- Issue #7860: platform.uname now reports the correct 'machine' type
600 when Python is running in WOW64 mode on 64 bit Windows.
601
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000602- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
603 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
604 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000605
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000606- Issue #4282: Fix the main function of the profile module for a non-ASCII

615
Benjamin Peterson689a5582010-03-18 22:29:52 +0000616- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
617 detected.
618

Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000629- The internals of the subprocess module on POSIX systems have been replaced
630 by an extension module (_posixsubprocess) so that the fork()+exec() can be
631 done safely without the possibility of deadlock in multithreaded applications.
632
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000633- subprocess.Popen now has restore_signals and start_new_session features.
634 The default of restore_signals=True is a new behavior compared to earlier
635 Python versions. This means that signals such as SIGPIPE are not ignored
636 by default in subprocesses launched by Python (Issue #1652).
637
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000638- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

698 exception of canonical and is_canonical) now accept instances of int
699 and long wherever a Decimal instance is accepted, and implicitly
700 convert that argument to Decimal. Previously only some arguments
701 were converted.

724 file position when calling `truncate()`. It would previously change the
725 file position to the given argument, which goes against the tradition of
726 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
727
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000728- Issue #7610: Reworked implementation of the internal
729 :class:`zipfile.ZipExtFile` class used to represent files stored inside
730 an archive. The new implementation is significantly faster and can
731 be wrapped in a :class:`io.BufferedReader` object for more speedups.
732 It also solves an issue where interleaved calls to `read()` and
733 `readline()` give wrong results. Patch by Nir Aides.

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000896- Issue #6816: runpy now provides a run_path function that allows Python code
897 to execute file paths that refer to source or compiled Python files as well
898 as zipfiles, directories and other valid sys.path entries that contain a
899 __main__.py file. This allows applications that run other Python scripts to
900 support the same flexibility as the CPython command line itself.
901
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000902- Issue #7318: multiprocessing now uses a timeout when it fails to establish

1386
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001387- Issue #7222: Make thread "reaping" more reliable so that reference
1388 leak-chasing test runs give sensible results. The previous method of
1389 reaping threads could return successfully while some Thread objects were
1390 still referenced. This also introduces a new private function:
1391 :func:`_thread._count()`.
1392
R. David Murray27144602009-10-19 15:26:16 +00001393- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1394 longer runs the risk of causing the worker thread to fail.
1395
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001396- Issue #7055: test___all__ now greedily detects all modules which have an
1397 __all__ attribute, rather than using a hardcoded and incomplete list.

1401 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001402
Mark Dickinson2e304402009-10-04 18:43:54 +00001403- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1404
Brett Cannon3c273842009-07-20 00:14:29 +00001405- Fixed tests in importlib.test.source.test_abc_loader that were masking
1406 the proper exceptions that should be raised for missing or improper code
1407 object bytecode.
1408
Brett Cannonb49c70c2009-07-15 04:08:33 +00001409- Removed importlib's custom test discovery code and switched to

1494 are always None now.
1495
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00001496- Issue #6137: The pickle module now translates module names when loading
1497 or dumping pickles with a 2.x-compatible protocol, in order to make data
1498 sharing and migration easier. This behaviour can be disabled using the
1499 new `fix_imports` optional argument.

1554 that would raise SystemError.
1555
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001556- Issue #5982: staticmethod and classmethod now expose the wrapped
1557 function with __func__.
1558
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001559- Added support for multiple context managers in the same with-statement.
1560 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001562- Issue #5829: complex("1e500") no longer raises OverflowError. This
1563 makes it consistent with float("1e500") and interpretation of real
1564 and imaginary literals.
1565
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001566- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1569
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001570- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1571 (1) inf and nan strings with trailing whitespace were incorrectly
1572 rejected; (2) parsing of strings representing infinities and nans
1573 was locale aware; and (3) the interpretation of fromhex('-nan')
1574 didn't match that of float('-nan').

1585
Georg Brandlfaf41492009-05-26 18:31:11 +00001586- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1587 arguments for strings with a space in them.
1588

1590 names: cls, self, tuple, itemgetter, and property.
1591
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001592- In unittest, using a skipping decorator on a class is now equivalent to
1593 skipping every test on the class. The ClassTestSuite class has been removed.
1594
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001595- Issue #6050: Don't fail extracting a directory from a zipfile if
1596 the directory already exists.
1597
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001598- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1599 than an int, which makes some operations possible under 64-bit Linux (e.g.
1600 DN_MULTISHOT with F_NOTIFY).
1601
Antoine Pitrou716c4442009-05-23 19:04:03 +00001602- Issue #5761: Add the name of the underlying file to the repr() of various

1606 by Musashi Tamura, tests by Marcin Bachry.
1607
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001608- Issue #1983: Fix functions taking or returning a process identifier to use
1609 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1610 a process identifier type wider than the standard C integer type.
1611
R. David Murray87e20742009-05-23 01:30:26 +00001612- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1623
Antoine Pitroue4501852009-05-14 18:55:55 +00001624- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1625 library. This means, for example, that opening an UTF-16 text file in
1626 append mode doesn't add a BOM at the end of the file if the file isn't
1627 empty.
1628
R. David Murray74b89242009-05-13 17:33:03 +00001629- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1630 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1631 corrects a pydoc regression.
1632
R. David Murray99352742009-05-07 18:24:38 +00001633- Issue 5955: aifc's close method did not close the file it wrapped,
1634 now it does. This also means getfp method now returns the real fp.
1635
Benjamin Peterson932073a2009-05-23 16:14:33 +00001636Installation
1637------------

1677Core and Builtins
1678-----------------
1679
Mark Dickinson865e01a2009-05-07 16:37:01 +00001680- Issue #5914: Add new C API function PyOS_string_to_double, and
1681 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1682
Eric Smith741191f2009-05-06 13:08:15 +00001683- Issue #3382: float.__format__, complex.__format__, and %-formatting
1684 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1685 affects nan -> NAN and inf -> INF.
1686
Mark Hammond5a607a32009-05-06 08:04:54 +00001687- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1688 in all operations, including splitdrive, split, etc. splitunc() now issues
1689 a PendingDeprecation warning.
1690
Eric Smith63376222009-05-05 14:04:18 +00001691- Issue #5920: For float.__format__, change the behavior with the
1692 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1693 to be like 'g' but with at least one decimal point and with a
1694 default precision of 12. Previously, the behavior the same but with
1695 a default precision of 6. This more closely matches str(), and
1696 reduces surprises when adding alignment flags to the empty
1697 presentation type. This also affects the new complex.__format__ in
1698 the same way.
1699
Martin v. Löwis011e8422009-05-05 04:43:17 +00001700- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1701
R. David Murrayb18500d2009-05-04 22:59:07 +00001702- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1703 shadowed by classtype's, even if it was None. property now
1704 inserts the __doc__ into the subclass instance __dict__.
1705
Antoine Pitrou244651a2009-05-04 18:56:13 +00001706- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1707 sequences. Patch by Nick Barnes and Victor Stinner.
1708
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001709- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001710
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001711- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1712 received a new method, detach(). detach() disconnects the underlying stream
1713 from the buffer or text IO and returns it.
1714
Mark Dickinson33841c32009-05-01 15:37:04 +00001715- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1716 floats with absolute value over 1e50. Also remove length
1717 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1718 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001719
Eric Smith741191f2009-05-06 13:08:15 +00001720- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001721 format(complex(1, 2./3), '.5') now produces a sensible result.
1722
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001723- Issue #5864: Fix empty format code formatting for floats so that it
1724 never gives more than the requested number of significant digits.
1725
Eric Smith6dc46f52009-04-27 20:39:49 +00001726- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1727 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1728
Eric Smithcc32a112009-04-26 21:35:14 +00001729- Issue #5835: Deprecate PyOS_ascii_formatd.
1730
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001731- Issue #4971: Fix titlecase for characters that are their own
1732 titlecase, but not their own uppercase.
1733
Benjamin Peterson193152c2009-04-25 01:08:45 +00001734- Issue #5283: Setting __class__ in __del__ caused a segfault.
1735
Mark Dickinsonad476da2009-04-23 19:14:16 +00001736- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1737 z involves nans, infs or negative zeros.
1738
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001739- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001740
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001741- Issue #1869 (and many duplicates): make round(x, n) correctly
1742 rounded for a float x, by using the decimal <-> binary conversions
1743 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1744 consistently agrees with format(x, '.2f').
1745
Benjamin Petersonae937c02009-04-18 20:54:08 +00001746- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1747 some builtin types.
1748
Eric Smith0923d1d2009-04-16 20:16:10 +00001749- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1750
Eric Smith35e84722009-04-16 20:21:28 +00001751- Issue #5515: str.format() type 'n' combined with commas and leading
1752 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001753
1754- Implement PEP 378, Format Specifier for Thousands Separator, for
1755 floats.
1756
Mark Dickinson3370cce2009-04-17 22:40:53 +00001757- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001758 1e11, not 1e12. This avoids printing 13 significant digits in
1759 situations where only 12 of them are correct. Example problem
1760 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1761 long time.)
1762
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001763- Issue #1580: On most platforms, use a 'short' float repr: for a
1764 finite float x, repr(x) now outputs a string based on the shortest
1765 sequence of decimal digits that rounds to x. Previous behaviour was
1766 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001767 Another minor difference is that the new repr switches to
1768 exponential notation at 1e16 instead of the previous 1e17; this
1769 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001770
1771 There's a new sys attribute sys.float_repr_style, which takes
1772 the value 'short' to indicate that we're using short float repr,
1773 and 'legacy' if the short float repr isn't available for one
1774 reason or another.
1775
1776 The float repr change involves incorporating David Gay's 'perfect
1777 rounding' code into the Python core (it's in Python/dtoa.c). As a
1778 secondary consequence, all string-to-float and float-to-string
1779 conversions (including all float formatting operations) will be
1780 correctly rounded on these platforms.
1781
1782 See issue 1580 discussions for details of platforms for which

1786
Georg Brandlabc38772009-04-12 15:51:51 +00001787- The string.maketrans() function is deprecated; there is a new static method

1789 the types string.maketrans() is supposed to work with, and mirrors the
1790 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002095- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002096 were suppressing all exceptions. These include list() and bytearray().
2097
Mark Dickinson1124e712009-01-28 21:25:58 +00002098- Issue #4707: round(x, n) now returns an integer if x is an integer.
2099 Previously it returned a float.
2100
Antoine Pitroub52ec782009-01-25 16:34:23 +00002101- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2102 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2103 evaluation loop is compiled with a new dispatch mechanism which gives
2104 speedups of up to 20%, depending on the system, on various benchmarks.
2105
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002106- Issue #4874: Most builtin decoders now reject unicode input.

2115
Mark Dickinson8055afd2009-01-17 10:04:45 +00002116- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2117 type to (void *).
2118
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002119- Issue #4935: The overflow checking code in the expandtabs() method common
2120 to str, bytes and bytearray could be optimized away by the compiler, letting
2121 the interpreter segfault instead of raising an error.
2122
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002123- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2124 __next__ method.
2125
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002126- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2127 function no longer attempt to call the __long__ slot to convert an object
2128 to an integer. Only the __int__ and __trunc__ slots are examined.

2133
Antoine Pitrouab868312009-01-10 15:40:25 +00002134- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2135 common cases are optimized thanks to a dedicated fast path and a moderate
2136 amount of loop unrolling.
2137
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002138- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2139 collecting the oldest generation) so that allocating lots of objects without
2140 destroying them does not show quadratic performance. Based on a proposal by
2141 Martin von Löwis at
2142 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2143
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002144- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002145 having been closed (for instance, a read() call could return some
2146 previously buffered data). Patch by Dmitry Vasiliev.
2147
Antoine Pitrou05608432009-01-09 18:53:14 +00002148- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2149 flag to work properly. Furthermore, when specifying -u, the text stdout
2150 and stderr streams have line-by-line buffering enabled (the default being
2151 to buffer arbitrary chunks of data).
2152
Raymond Hettinger35631532009-01-09 03:58:09 +00002153- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2154 instead of ints (reducing its size from 4 to 8 times thereby reducing
2155 Python's overall memory).
2156
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002157- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2158 an existing .py counterpart, override the co_filename attributes of all
2159 code objects if the original filename is obsolete (which can happen if the
2160 file has been renamed, moved, or if it is accessed through different paths).
2161 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2162
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002163- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2164 one byte. Also fixes the meaning of len() so that it returns the number of
2165 items, rather than the size in bytes.
2166
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002167- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2168
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002169- Issue #4747: When the terminal does not use utf-8, executing a script with
2170 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2171

2176 did not get collected.
2177
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002178- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2179 where the tp_hash and tp_dict slots are both NULL.
2180
Georg Brandlccc47b62008-12-28 11:44:14 +00002181- Issue #4759: None is now allowed as the first argument of
2182 bytearray.translate(). It was always allowed for bytes.translate().
2183
Skip Montanaro80072cb2008-12-23 03:51:14 +00002184- Added test case to ensure attempts to read from a file opened for writing
2185 fail.

2191
Antoine Pitrou621601a2008-12-17 23:18:19 +00002192- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00002198- Issue #2173: When getting device encoding, check that return value of
2199 nl_langinfo is not the empty string. This was causing silent build
2200 failures on OS X.
2201
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002202- Issue #4597: Fixed several opcodes that weren't always propagating
2203 exceptions.
2204
2205- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002206 context manager returns a value that cannot be converted to a bool.
2207
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002208- Issue #4445: Replace "sizeof(PyBytesObject)" with
2209 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2210 bytes instances. On a typical machine this saves 3 bytes of memory
2211 (on average) per allocation of a bytes instance.
2212
Christian Heimesa872de52008-12-05 08:26:55 +00002213- Issue #4533: File read operation was dreadfully slow due to a slowly
2214 growing read buffer. Fixed by using the same growth rate algorithm as
2215 Python 2.x.
2216
Antoine Pitrou5504e892008-12-06 21:27:53 +00002217- Issue #4509: Various issues surrounding resize of bytearray objects to
2218 which there are buffer exports (e.g. memoryview instances).
2219
Georg Brandlf9734072008-12-07 15:30:06 +00002220- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2221 method on file objects with closefd=False. The file descriptor is still
2222 kept open but the file object behaves like a closed file. The ``FileIO``
2223 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002232- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2233 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2234 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2235 of using the replace error handler in PyUnicode_DecodeUTF8().
