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

185 over range(a, b, c) incorrectly gave an empty iterator when a, b and
186 c fit in C long but the length of the range did not. Also fix

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 class.
356
Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000357- Issue #8664: In py_compile, create __pycache__ when the compiled path is
358 given.
359
Victor Stinner449c4662010-05-08 11:10:09 +0000360- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
361 for use in the file system, environment variables or the command line.
362
Antoine Pitrou89562712010-05-07 17:04:02 +0000363- Issue #8571: Fix an internal error when compressing or decompressing a

365 objects.
366
Benjamin Peterson225168e2010-05-06 22:29:53 +0000367- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
368 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
369 file system encoding with the surrogateescape error handler (instead of
370 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000371
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000372- Issue #8573: asyncore _strerror() function might throw ValueError.
373
374- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
375 error messages when accessing undefined class attributes because of the cheap
376 inheritance with the underlying socket object.
377 The cheap inheritance has been deprecated.

Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000379- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
380 Patch by Tres Seaver.
381
Victor Stinnerde629d42010-05-05 21:43:57 +0000382- Issue #8390: tarfile uses surrogateespace as the default error handler
383 (instead of replace in read mode or strict in write mode)
384
Barry Warsaw83d89982010-05-05 16:18:31 +0000385- Issue #7755: Use an unencumbered audio file for tests.

Ronald Oussorenac764d32010-05-05 15:32:33 +0000387- Issue #8621: uuid.uuid4() returned the same sequence of values in the
388 parent and any children created using ``os.fork`` on MacOS X 10.6.
389
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000390- Issue #8567: Fix precedence of signals in Decimal module: when a
391 Decimal operation raises multiple signals and more than one of those
392 signals is trapped, the specification determines the order in which
393 the signals should be handled. In many cases this order wasn't
394 being followed, leading to the wrong Python exception being raised.
395
Antoine Pitrou6be88762010-05-03 16:48:20 +0000396- Issue #7865: The close() method of :mod:`io` objects should not swallow
397 exceptions raised by the implicit flush(). Also ensure that calling
398 close() several times is supported. Patch by Pascal Chambon.
399
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000400- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
401 gc.DEBUG_STATS.
402
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000403- Issue #8354: The siginterrupt setting is now preserved for all signals,
404 not just SIGCHLD.
405
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000406- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
407 webbrowser.get("safari").
408
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000409- Issue #8464: tarfile no longer creates files with execute permissions set
410 when mode="w|" is used.
411
Antoine Pitroubf043492010-04-29 10:11:46 +0000412- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
413 of the Linux kernel. Patch by Yaniv Aknin.
414
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000415- Issue #8295: Added shutil.unpack_archive.
416
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000417- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
418 It should correctly return an empty response now.
419
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000420- Issue #8546: Reject None given as the buffering argument to _pyio.open.

R. David Murrayad78d152010-04-27 02:45:53 +0000425- Issue #6656: fix locale.format_string to handle escaped percents
426 and mappings.
427
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000428- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
429 where the method could block indefinitely if called just before the
430 event loop started running. This also fixes the occasional freezes
431 witnessed in test_httpservers.
432
Antoine Pitrou40f08742010-04-24 22:04:40 +0000433- Issue #8524: When creating an SSL socket, the timeout value of the
434 original socket wasn't retained (instead, a socket with a positive timeout
435 would be turned into a non-blocking SSL socket).
436
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000437- Issue #5103: SSL handshake would ignore the socket timeout and block
438 indefinitely if the other end didn't respond.
439
440- The do_handshake() method of SSL objects now adjusts the blocking mode of
441 the SSL structure if necessary (as other methods already do).
442
Victor Stinner13bb71c2010-04-23 21:41:56 +0000443- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
444 and bytes strings for environment keys and values
445
Victor Stinner4d078042010-04-23 19:28:32 +0000446- Issue #8467: Pure Python implementation of subprocess encodes the error
447 message using surrogatepass error handler to support surrogates in the
448 message
449
Victor Stinner349fd522010-04-23 10:56:17 +0000450- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
451
Sean Reifscheider13daf122010-04-23 09:29:52 +0000452- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
453 the string "python" as the *ident*. openlog() arguments are all optional
454 and keywords.
455
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000456- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
457 a non-infinite timeout. Also make that method friendlier with applications
458 wanting to continue using the socket in clear-text mode, by disabling
459 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
460
Antoine Pitrou7062db82010-04-22 13:30:10 +0000461- Issue #8496: make mailcap.lookup() always return a list, rather than an
462 iterator. Patch by Gregory Nofi.
463
Victor Stinner35466c52010-04-22 11:23:23 +0000464- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
465 collation name contains a surrogate character.
466
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000467- Issue #8484: Load all ciphers and digest algorithms when initializing
468 the _ssl extension, such that verification of some SSL certificates
469 doesn't fail because of an "unknown algorithm".
470
Tarek Ziadéfb437512010-04-20 08:57:33 +0000471- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
472
Tarek Ziadé5340db32010-04-19 22:30:51 +0000473- Issue #1540112: Now allowing the choice of a copy function in
474 shutil.copytree.
475
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000476- Issue #4814: timeout parameter is now applied also for connections resulting
477 from PORT/EPRT commands.
478
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000479- Issue #8463: added missing reference to bztar in shutil's documentation.
480
Ronald Oussoren84151202010-04-18 20:46:11 +0000481- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
482 (as long as the user didn't specify 'automatic proxy configuration').
483
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000484- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
485 code as stated in RFC-959 at chapter 5.4.
486
Victor Stinner738446f02010-04-18 00:00:44 +0000487- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
488 surrogates.
489
Antoine Pitrou0454af92010-04-17 23:51:58 +0000490- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000491 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000493- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
494 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
495
Victor Stinner0e59cc32010-04-16 23:49:32 +0000496- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
497 the current working directory.
498
Victor Stinner5bfe1462010-04-16 13:28:05 +0000499- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
500 using backslashreplace error handler
501
Victor Stinnercfa72782010-04-16 11:45:13 +0000502- Issue #8412: os.system() now accepts bytes, bytearray and str with
503 surrogates.
504
Senthil Kumaranad02d232010-04-16 03:02:13 +0000505- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony

R. David Murrayd48739f2010-04-14 18:59:18 +0000508- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
509
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000510- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
511 module now takes an optional timeout argument in seconds. Timeout support
512 relies on the system threading library, so as to avoid a semi-busy wait
513 loop.
514
Victor Stinner485fb562010-04-13 11:07:24 +0000515- Issue #8383: pickle and pickletools use surrogatepass error handler when
516 encoding unicode as utf8 to support lone surrogates and stay compatible with
517 Python 2.x and 3.0
518
R. David Murrayb2416e52010-04-12 16:58:02 +0000519- Issue #7585: difflib context and unified diffs now place a tab between
520 filename and date, conforming to the 'standards' they were originally
521 designed to follow. This improves compatibility with patch tools.
522
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000523- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
524 character sets will now consistently use a Content-Transfer-Encoding of
525 7bit rather than sometimes being marked as 8bit.
526
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000527- Issue #8375: test_distutils now checks if the temporary directory are still
528 present before it cleans them.
529
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000530- Issue #8374: Update the internal alias table in the :mod:`locale` module
531 to cover recent locale changes and additions.
532
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000533- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
534 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
535 and `ssl.OPENSSL_VERSION_NUMBER`.
536
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000537- Add functools.total_ordering() and functools.cmp_to_key().
538
Mark Dickinson089b00c2010-04-03 15:51:03 +0000539- Issue #8257: The Decimal construct now accepts a float instance
540 directly, converting that float to a Decimal of equal value:
541
542 >>> Decimal(1.1)
543 Decimal('1.100000000000000088817841970012523233890533447265625')
544
Mark Dickinson98127c32010-04-03 11:18:52 +0000545- Issue #8294: The Fraction constructor now accepts Decimal and float
546 instances directly.
547
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000548- Issue #7279: Comparisons involving a Decimal signaling NaN now
549 signal InvalidOperation instead of returning False. (Comparisons
550 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
551 are now hashable; Decimal signaling NaNs remain unhashable.
552
553- Issue #2531: Comparison operations between floats and Decimal
554 instances now return a result based on the numeric values of the
555 operands; previously they returned an arbitrary result based on
556 the relative ordering of id(float) and id(Decimal).
557
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000558- Added a subtract() method to collections.Counter().
559
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000560- Issue #8233: When run as a script, py_compile.py optionally takes a single
561 argument `-` which tells it to read files to compile from stdin. Each line
562 is read on demand and the named file is compiled immediately. (Original
563 patch by Piotr Ożarowski).
564
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000565- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
566 form feed (0x0C) are now considered linebreaks, as specified in Unicode
567 Standard Annex #14. See issue #7643.
568 http://www.unicode.org/reports/tr14/
569
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000570- Comparisons using one of <, <=, >, >= between a complex instance and
571 a Fractions instance now raise TypeError instead of returning
572 True/False. This makes Fraction <=> complex comparisons consistent with
573 int <=> complex, float <=> complex, and complex <=> complex comparisons.
574
Antoine Pitrou39b35432010-03-23 00:25:54 +0000575- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
576 some methods (such as oss_mixer_device.fileno()) were not available.
577 Initial patch by Bertrand Janin.
578
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000579- Issue #8205: Remove the "Modules" directory from sys.path when Python is
580 running from the build directory (POSIX only).
581
Antoine Pitrou910bd512010-03-22 20:11:09 +0000582- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
583 didn't support chflags() (for example ZFS under FreeBSD). The error is
584 now silenced.
585
R. David Murrayca2edce2010-03-22 17:48:48 +0000586- Issue #7860: platform.uname now reports the correct 'machine' type
587 when Python is running in WOW64 mode on 64 bit Windows.
588
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000589- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
590 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
591 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000592
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000593- Issue #4282: Fix the main function of the profile module for a non-ASCII
594 script, open the file in binary mode and not in text mode with the default
595 (utf8) encoding.
596
Florent Xicluna54467e02010-03-21 12:29:50 +0000597- Issue #8179: Fix macpath.realpath() on a non-existing path.

Benjamin Peterson00888932010-03-18 22:37:38 +0000601- Issue #8168: py_compile now handles files with utf-8 BOMS.
602
Benjamin Peterson689a5582010-03-18 22:29:52 +0000603- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
604 detected.
605
Martin v. Löwis4b003072010-03-16 13:19:21 +0000606- Issue #6716/2: Backslash-replace error output in compilall.
607
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000608- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
609 with Tcl/Tk-8.5.
610
Matthias Klosec33b9022010-03-16 00:36:26 +0000611- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000613- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
614 the locale.
615
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000616- The internals of the subprocess module on POSIX systems have been replaced
617 by an extension module (_posixsubprocess) so that the fork()+exec() can be
618 done safely without the possibility of deadlock in multithreaded applications.
619
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000620- subprocess.Popen now has restore_signals and start_new_session features.
621 The default of restore_signals=True is a new behavior compared to earlier
622 Python versions. This means that signals such as SIGPIPE are not ignored

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

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

1361 between concurrent executions on the same system.
1362
Brett Cannon0ae45112009-11-05 01:17:22 +00001363- Issue #7248: In importlib.test.source.util a try/finally block did not make

1365 calling methods on the object.
1366
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001367- Issue #7222: Make thread "reaping" more reliable so that reference
1368 leak-chasing test runs give sensible results. The previous method of
1369 reaping threads could return successfully while some Thread objects were
1370 still referenced. This also introduces a new private function:
1371 :func:`_thread._count()`.
1372
R. David Murray27144602009-10-19 15:26:16 +00001373- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1374 longer runs the risk of causing the worker thread to fail.
1375
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001376- Issue #7055: test___all__ now greedily detects all modules which have an
1377 __all__ attribute, rather than using a hardcoded and incomplete list.

1380 runtest_inner in regrtest, with warnings if the called test modifies them,
1381 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001382
Mark Dickinson2e304402009-10-04 18:43:54 +00001383- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1384
Brett Cannon3c273842009-07-20 00:14:29 +00001385- Fixed tests in importlib.test.source.test_abc_loader that were masking
1386 the proper exceptions that should be raised for missing or improper code
1387 object bytecode.
1388
Brett Cannonb49c70c2009-07-15 04:08:33 +00001389- Removed importlib's custom test discovery code and switched to

1534 that would raise SystemError.
1535
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001536- Issue #5982: staticmethod and classmethod now expose the wrapped
1537 function with __func__.
1538
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001539- Added support for multiple context managers in the same with-statement.
1540 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001542- Issue #5829: complex("1e500") no longer raises OverflowError. This
1543 makes it consistent with float("1e500") and interpretation of real
1544 and imaginary literals.
1545
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001546- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1547
R. David Murraydd226ea2009-05-13 12:27:21 +00001548- Issue #5994: the marshal module now has docstrings.
1549
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001550- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1551 (1) inf and nan strings with trailing whitespace were incorrectly
1552 rejected; (2) parsing of strings representing infinities and nans
1553 was locale aware; and (3) the interpretation of fromhex('-nan')
1554 didn't match that of float('-nan').

1562
R. David Murray1f1b9d32009-05-27 20:56:59 +00001563- Issue #6121: pydoc now ignores leading and trailing spaces in the
1564 argument to the 'help' function.
1565
Georg Brandlfaf41492009-05-26 18:31:11 +00001566- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1567 arguments for strings with a space in them.
1568
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001569- collections.namedtuple() was not working with the following field
1570 names: cls, self, tuple, itemgetter, and property.
1571
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001572- In unittest, using a skipping decorator on a class is now equivalent to
1573 skipping every test on the class. The ClassTestSuite class has been removed.
1574
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001575- Issue #6050: Don't fail extracting a directory from a zipfile if
1576 the directory already exists.
1577
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001578- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1579 than an int, which makes some operations possible under 64-bit Linux (e.g.
1580 DN_MULTISHOT with F_NOTIFY).
1581
Antoine Pitrou716c4442009-05-23 19:04:03 +00001582- Issue #5761: Add the name of the underlying file to the repr() of various

1587
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001588- Issue #1983: Fix functions taking or returning a process identifier to use
1589 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1590 a process identifier type wider than the standard C integer type.
1591
R. David Murray87e20742009-05-23 01:30:26 +00001592- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1603
Antoine Pitroue4501852009-05-14 18:55:55 +00001604- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1605 library. This means, for example, that opening an UTF-16 text file in
1606 append mode doesn't add a BOM at the end of the file if the file isn't
1607 empty.
1608
R. David Murray74b89242009-05-13 17:33:03 +00001609- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1610 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1611 corrects a pydoc regression.
1612
R. David Murray99352742009-05-07 18:24:38 +00001613- Issue 5955: aifc's close method did not close the file it wrapped,
1614 now it does. This also means getfp method now returns the real fp.

1657Core and Builtins
1658-----------------
1659
Mark Dickinson865e01a2009-05-07 16:37:01 +00001660- Issue #5914: Add new C API function PyOS_string_to_double, and
1661 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1662
Eric Smith741191f2009-05-06 13:08:15 +00001663- Issue #3382: float.__format__, complex.__format__, and %-formatting
1664 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1665 affects nan -> NAN and inf -> INF.
1666
Mark Hammond5a607a32009-05-06 08:04:54 +00001667- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1668 in all operations, including splitdrive, split, etc. splitunc() now issues
1669 a PendingDeprecation warning.
1670
Eric Smith63376222009-05-05 14:04:18 +00001671- Issue #5920: For float.__format__, change the behavior with the
1672 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1673 to be like 'g' but with at least one decimal point and with a
1674 default precision of 12. Previously, the behavior the same but with
1675 a default precision of 6. This more closely matches str(), and
1676 reduces surprises when adding alignment flags to the empty
1677 presentation type. This also affects the new complex.__format__ in
1678 the same way.
1679
Martin v. Löwis011e8422009-05-05 04:43:17 +00001680- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1681
R. David Murrayb18500d2009-05-04 22:59:07 +00001682- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1683 shadowed by classtype's, even if it was None. property now
1684 inserts the __doc__ into the subclass instance __dict__.
1685
Antoine Pitrou244651a2009-05-04 18:56:13 +00001686- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1687 sequences. Patch by Nick Barnes and Victor Stinner.
1688
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001689- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001690
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001691- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1692 received a new method, detach(). detach() disconnects the underlying stream
1693 from the buffer or text IO and returns it.
1694
Mark Dickinson33841c32009-05-01 15:37:04 +00001695- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1696 floats with absolute value over 1e50. Also remove length
1697 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1698 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001699
Eric Smith741191f2009-05-06 13:08:15 +00001700- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001701 format(complex(1, 2./3), '.5') now produces a sensible result.
1702
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001703- Issue #5864: Fix empty format code formatting for floats so that it
1704 never gives more than the requested number of significant digits.
1705
Eric Smith6dc46f52009-04-27 20:39:49 +00001706- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1707 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1708
Eric Smithcc32a112009-04-26 21:35:14 +00001709- Issue #5835: Deprecate PyOS_ascii_formatd.
1710
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001711- Issue #4971: Fix titlecase for characters that are their own
1712 titlecase, but not their own uppercase.
1713
Benjamin Peterson193152c2009-04-25 01:08:45 +00001714- Issue #5283: Setting __class__ in __del__ caused a segfault.
1715
Mark Dickinsonad476da2009-04-23 19:14:16 +00001716- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1717 z involves nans, infs or negative zeros.
1718
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001719- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001720
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001721- Issue #1869 (and many duplicates): make round(x, n) correctly
1722 rounded for a float x, by using the decimal <-> binary conversions
1723 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1724 consistently agrees with format(x, '.2f').
1725
Benjamin Petersonae937c02009-04-18 20:54:08 +00001726- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1727 some builtin types.
1728
Eric Smith0923d1d2009-04-16 20:16:10 +00001729- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1730
Eric Smith35e84722009-04-16 20:21:28 +00001731- Issue #5515: str.format() type 'n' combined with commas and leading
1732 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001733
1734- Implement PEP 378, Format Specifier for Thousands Separator, for
1735 floats.
1736
Mark Dickinson3370cce2009-04-17 22:40:53 +00001737- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001738 1e11, not 1e12. This avoids printing 13 significant digits in
1739 situations where only 12 of them are correct. Example problem
1740 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1741 long time.)
1742
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001743- Issue #1580: On most platforms, use a 'short' float repr: for a
1744 finite float x, repr(x) now outputs a string based on the shortest
1745 sequence of decimal digits that rounds to x. Previous behaviour was
1746 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001747 Another minor difference is that the new repr switches to
1748 exponential notation at 1e16 instead of the previous 1e17; this
1749 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001750
1751 There's a new sys attribute sys.float_repr_style, which takes
1752 the value 'short' to indicate that we're using short float repr,
1753 and 'legacy' if the short float repr isn't available for one
1754 reason or another.
1755
1756 The float repr change involves incorporating David Gay's 'perfect
1757 rounding' code into the Python core (it's in Python/dtoa.c). As a
1758 secondary consequence, all string-to-float and float-to-string
1759 conversions (including all float formatting operations) will be
1760 correctly rounded on these platforms.
1761
1762 See issue 1580 discussions for details of platforms for which
1763 this change does not apply.
1764
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001765- Issue #5759: float() didn't call __float__ on str subclasses.
1766
Georg Brandlabc38772009-04-12 15:51:51 +00001767- The string.maketrans() function is deprecated; there is a new static method
1768 maketrans() on the bytes and bytearray classes. This removes confusion about
1769 the types string.maketrans() is supposed to work with, and mirrors the
1770 methods available on the str class.
1771
R. David Murraydc6da8a2009-04-09 22:16:43 +00001772- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1773 its clarity and its speed.
1774
Matthias Klose091c7b12009-04-07 13:24:27 +00001775- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1776 to avoid compiler warnings.
1777
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001778- Issue #3739: The unicode-internal encoder now reports the number of characters
1779 consumed like any other encoder (instead of the number of bytes).

Antoine Pitroub52ec782009-01-25 16:34:23 +00002081- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2082 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2083 evaluation loop is compiled with a new dispatch mechanism which gives
2084 speedups of up to 20%, depending on the system, on various benchmarks.
2085
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002086- Issue #4874: Most builtin decoders now reject unicode input.

2092
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002093- Issue #4838: When a module is deallocated, free the memory backing the
2094 optional module state data.
2095
Mark Dickinson8055afd2009-01-17 10:04:45 +00002096- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2097 type to (void *).
2098
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002099- Issue #4935: The overflow checking code in the expandtabs() method common
2100 to str, bytes and bytearray could be optimized away by the compiler, letting
2101 the interpreter segfault instead of raising an error.
2102
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002103- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2104 __next__ method.
2105
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002106- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2107 function no longer attempt to call the __long__ slot to convert an object
2108 to an integer. Only the __int__ and __trunc__ slots are examined.

2113
Antoine Pitrouab868312009-01-10 15:40:25 +00002114- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2115 common cases are optimized thanks to a dedicated fast path and a moderate
2116 amount of loop unrolling.
2117
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002118- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2119 collecting the oldest generation) so that allocating lots of objects without
2120 destroying them does not show quadratic performance. Based on a proposal by
2121 Martin von Löwis at
2122 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2123
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002124- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002125 having been closed (for instance, a read() call could return some
2126 previously buffered data). Patch by Dmitry Vasiliev.
2127
Antoine Pitrou05608432009-01-09 18:53:14 +00002128- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2129 flag to work properly. Furthermore, when specifying -u, the text stdout
2130 and stderr streams have line-by-line buffering enabled (the default being
2131 to buffer arbitrary chunks of data).
2132
Raymond Hettinger35631532009-01-09 03:58:09 +00002133- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2134 instead of ints (reducing its size from 4 to 8 times thereby reducing
2135 Python's overall memory).
2136
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002137- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2138 an existing .py counterpart, override the co_filename attributes of all
2139 code objects if the original filename is obsolete (which can happen if the
2140 file has been renamed, moved, or if it is accessed through different paths).
2141 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2142
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002143- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2144 one byte. Also fixes the meaning of len() so that it returns the number of
2145 items, rather than the size in bytes.
2146
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002147- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2148
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002149- Issue #4747: When the terminal does not use utf-8, executing a script with
2150 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2151
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002152- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

2156 did not get collected.
2157
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002158- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2159 where the tp_hash and tp_dict slots are both NULL.
2160
Georg Brandlccc47b62008-12-28 11:44:14 +00002161- Issue #4759: None is now allowed as the first argument of
2162 bytearray.translate(). It was always allowed for bytes.translate().
2163
Skip Montanaro80072cb2008-12-23 03:51:14 +00002164- Added test case to ensure attempts to read from a file opened for writing
2165 fail.

2171
Antoine Pitrou621601a2008-12-17 23:18:19 +00002172- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2177
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002178- Issue #2173: When getting device encoding, check that return value of
2179 nl_langinfo is not the empty string. This was causing silent build
2180 failures on OS X.
2181
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002182- Issue #4597: Fixed several opcodes that weren't always propagating
2183 exceptions.
2184
2185- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002186 context manager returns a value that cannot be converted to a bool.
2187
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002188- Issue #4445: Replace "sizeof(PyBytesObject)" with
2189 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2190 bytes instances. On a typical machine this saves 3 bytes of memory
2191 (on average) per allocation of a bytes instance.
2192
Christian Heimesa872de52008-12-05 08:26:55 +00002193- Issue #4533: File read operation was dreadfully slow due to a slowly
2194 growing read buffer. Fixed by using the same growth rate algorithm as
2195 Python 2.x.
2196
Antoine Pitrou5504e892008-12-06 21:27:53 +00002197- Issue #4509: Various issues surrounding resize of bytearray objects to
2198 which there are buffer exports (e.g. memoryview instances).
2199
Georg Brandlf9734072008-12-07 15:30:06 +00002200- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2201 method on file objects with closefd=False. The file descriptor is still
2202 kept open but the file object behaves like a closed file. The ``FileIO``
2203 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002205- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2211
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002212- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2213 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2214 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2215 of using the replace error handler in PyUnicode_DecodeUTF8().
