104 deprecations.
105
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000106- Issue #7385: Fix a crash in `MemoryView_FromObject` when

108
Mark Dickinsonbc099642010-01-29 17:27:24 +0000109- Issue #7788: Fix an interpreter crash produced by deleting a list
110 slice with very large step value.
111
Eric Smithf7bb5782010-01-27 00:44:57 +0000112- Issue #7766: Change sys.getwindowsversion() return value to a named
113 tuple and add the additional members returned in an OSVERSIONINFOEX

116
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000117- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
118 could crash in many places because of the PyByteArray_AS_STRING() macro
119 returning NULL. The macro now returns a statically allocated empty
120 string instead.
121
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000122- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
123 where the right hand operand is a set of constants, by turning the set into
124 a frozenset and pre-building it as a constant. The comparison operation
125 is made against the constant instead of building a new set each time it is
126 executed (a similar optimization already existed which turned a list of
127 constants into a pre-built tuple). Patch and additional tests by Dave
128 Malcolm.
129
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000130- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

135 alpha 2, including: (1) a serious 'wrong output' bug that could
136 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
137 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000138 strings corresponding to subnormal values, (3) a memory leak for
139 some values large enough to cause overflow, and (4) a number of
140 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000141
Benjamin Petersonaea44282010-01-04 01:10:28 +0000142- The __complex__ method is now looked up on the class of instances to make it

153 described in C99 Annex F.
154
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000155- Issue #1811: improve accuracy and cross-platform consistency for
156 true division of integers: the result of a/b is now correctly
157 rounded for ints a and b (at least on IEEE 754 platforms), and in
158 particular does not depend on the internal representation of an int.
159
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000160- Issue #6834: replace the implementation for the 'python' and 'pythonw'
161 executables on OSX.
162

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

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

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

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

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

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

1352 between concurrent executions on the same system.
1353
Brett Cannon0ae45112009-11-05 01:17:22 +00001354- Issue #7248: In importlib.test.source.util a try/finally block did not make

1356 calling methods on the object.
1357
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001358- Issue #7222: Make thread "reaping" more reliable so that reference
1359 leak-chasing test runs give sensible results. The previous method of
1360 reaping threads could return successfully while some Thread objects were
1361 still referenced. This also introduces a new private function:
1362 :func:`_thread._count()`.
1363
R. David Murray27144602009-10-19 15:26:16 +00001364- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1365 longer runs the risk of causing the worker thread to fail.
1366
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001367- Issue #7055: test___all__ now greedily detects all modules which have an
1368 __all__ attribute, rather than using a hardcoded and incomplete list.

1371 runtest_inner in regrtest, with warnings if the called test modifies them,
1372 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001373
Mark Dickinson2e304402009-10-04 18:43:54 +00001374- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1375
Brett Cannon3c273842009-07-20 00:14:29 +00001376- Fixed tests in importlib.test.source.test_abc_loader that were masking
1377 the proper exceptions that should be raised for missing or improper code
1378 object bytecode.
1379
Brett Cannonb49c70c2009-07-15 04:08:33 +00001380- Removed importlib's custom test discovery code and switched to

1525 that would raise SystemError.
1526
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001527- Issue #5982: staticmethod and classmethod now expose the wrapped
1528 function with __func__.
1529
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001530- Added support for multiple context managers in the same with-statement.
1531 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001533- Issue #5829: complex("1e500") no longer raises OverflowError. This
1534 makes it consistent with float("1e500") and interpretation of real
1535 and imaginary literals.
1536
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001537- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001541- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1542 (1) inf and nan strings with trailing whitespace were incorrectly
1543 rejected; (2) parsing of strings representing infinities and nans
1544 was locale aware; and (3) the interpretation of fromhex('-nan')
1545 didn't match that of float('-nan').

1561 names: cls, self, tuple, itemgetter, and property.
1562
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001563- In unittest, using a skipping decorator on a class is now equivalent to
1564 skipping every test on the class. The ClassTestSuite class has been removed.
1565
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001566- Issue #6050: Don't fail extracting a directory from a zipfile if
1567 the directory already exists.
1568
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001569- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1570 than an int, which makes some operations possible under 64-bit Linux (e.g.
1571 DN_MULTISHOT with F_NOTIFY).
1572
Antoine Pitrou716c4442009-05-23 19:04:03 +00001573- Issue #5761: Add the name of the underlying file to the repr() of various

1577 by Musashi Tamura, tests by Marcin Bachry.
1578
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001579- Issue #1983: Fix functions taking or returning a process identifier to use
1580 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1581 a process identifier type wider than the standard C integer type.
1582
R. David Murray87e20742009-05-23 01:30:26 +00001583- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1594
Antoine Pitroue4501852009-05-14 18:55:55 +00001595- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1596 library. This means, for example, that opening an UTF-16 text file in
1597 append mode doesn't add a BOM at the end of the file if the file isn't
1598 empty.
1599
R. David Murray74b89242009-05-13 17:33:03 +00001600- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1601 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1602 corrects a pydoc regression.
1603
R. David Murray99352742009-05-07 18:24:38 +00001604- Issue 5955: aifc's close method did not close the file it wrapped,
1605 now it does. This also means getfp method now returns the real fp.

1648Core and Builtins
1649-----------------
1650
Mark Dickinson865e01a2009-05-07 16:37:01 +00001651- Issue #5914: Add new C API function PyOS_string_to_double, and
1652 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1653
Eric Smith741191f2009-05-06 13:08:15 +00001654- Issue #3382: float.__format__, complex.__format__, and %-formatting
1655 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1656 affects nan -> NAN and inf -> INF.
1657
Mark Hammond5a607a32009-05-06 08:04:54 +00001658- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1659 in all operations, including splitdrive, split, etc. splitunc() now issues
1660 a PendingDeprecation warning.
1661
Eric Smith63376222009-05-05 14:04:18 +00001662- Issue #5920: For float.__format__, change the behavior with the
1663 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1664 to be like 'g' but with at least one decimal point and with a
1665 default precision of 12. Previously, the behavior the same but with
1666 a default precision of 6. This more closely matches str(), and
1667 reduces surprises when adding alignment flags to the empty
1668 presentation type. This also affects the new complex.__format__ in
1669 the same way.
1670
Martin v. Löwis011e8422009-05-05 04:43:17 +00001671- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1672
R. David Murrayb18500d2009-05-04 22:59:07 +00001673- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1674 shadowed by classtype's, even if it was None. property now
1675 inserts the __doc__ into the subclass instance __dict__.
1676
Antoine Pitrou244651a2009-05-04 18:56:13 +00001677- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1678 sequences. Patch by Nick Barnes and Victor Stinner.
1679
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001680- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001681
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001682- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1683 received a new method, detach(). detach() disconnects the underlying stream
1684 from the buffer or text IO and returns it.
1685
Mark Dickinson33841c32009-05-01 15:37:04 +00001686- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1687 floats with absolute value over 1e50. Also remove length
1688 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1689 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001690
Eric Smith741191f2009-05-06 13:08:15 +00001691- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001692 format(complex(1, 2./3), '.5') now produces a sensible result.
1693
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001694- Issue #5864: Fix empty format code formatting for floats so that it
1695 never gives more than the requested number of significant digits.
1696
Eric Smith6dc46f52009-04-27 20:39:49 +00001697- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1698 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1699
Eric Smithcc32a112009-04-26 21:35:14 +00001700- Issue #5835: Deprecate PyOS_ascii_formatd.
1701
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001702- Issue #4971: Fix titlecase for characters that are their own
1703 titlecase, but not their own uppercase.
1704
Benjamin Peterson193152c2009-04-25 01:08:45 +00001705- Issue #5283: Setting __class__ in __del__ caused a segfault.
1706
Mark Dickinsonad476da2009-04-23 19:14:16 +00001707- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1708 z involves nans, infs or negative zeros.
1709
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001710- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001711
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001712- Issue #1869 (and many duplicates): make round(x, n) correctly
1713 rounded for a float x, by using the decimal <-> binary conversions
1714 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1715 consistently agrees with format(x, '.2f').
1716
Benjamin Petersonae937c02009-04-18 20:54:08 +00001717- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1718 some builtin types.
1719
Eric Smith0923d1d2009-04-16 20:16:10 +00001720- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1721
Eric Smith35e84722009-04-16 20:21:28 +00001722- Issue #5515: str.format() type 'n' combined with commas and leading
1723 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001724
1725- Implement PEP 378, Format Specifier for Thousands Separator, for
1726 floats.
1727
Mark Dickinson3370cce2009-04-17 22:40:53 +00001728- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001729 1e11, not 1e12. This avoids printing 13 significant digits in
1730 situations where only 12 of them are correct. Example problem
1731 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1732 long time.)
1733
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001734- Issue #1580: On most platforms, use a 'short' float repr: for a
1735 finite float x, repr(x) now outputs a string based on the shortest
1736 sequence of decimal digits that rounds to x. Previous behaviour was
1737 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001738 Another minor difference is that the new repr switches to
1739 exponential notation at 1e16 instead of the previous 1e17; this
1740 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001741
1742 There's a new sys attribute sys.float_repr_style, which takes
1743 the value 'short' to indicate that we're using short float repr,
1744 and 'legacy' if the short float repr isn't available for one
1745 reason or another.
1746
1747 The float repr change involves incorporating David Gay's 'perfect
1748 rounding' code into the Python core (it's in Python/dtoa.c). As a
1749 secondary consequence, all string-to-float and float-to-string
1750 conversions (including all float formatting operations) will be
1751 correctly rounded on these platforms.
1752
1753 See issue 1580 discussions for details of platforms for which
1754 this change does not apply.
1755
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001756- Issue #5759: float() didn't call __float__ on str subclasses.
1757
Georg Brandlabc38772009-04-12 15:51:51 +00001758- The string.maketrans() function is deprecated; there is a new static method
1759 maketrans() on the bytes and bytearray classes. This removes confusion about
1760 the types string.maketrans() is supposed to work with, and mirrors the
1761 methods available on the str class.
1762
R. David Murraydc6da8a2009-04-09 22:16:43 +00001763- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1764 its clarity and its speed.
1765
Matthias Klose091c7b12009-04-07 13:24:27 +00001766- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1767 to avoid compiler warnings.
1768
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001769- Issue #3739: The unicode-internal encoder now reports the number of characters
1770 consumed like any other encoder (instead of the number of bytes).

2083
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002084- Issue #4838: When a module is deallocated, free the memory backing the
2085 optional module state data.
2086
Mark Dickinson8055afd2009-01-17 10:04:45 +00002087- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2088 type to (void *).
2089
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002090- Issue #4935: The overflow checking code in the expandtabs() method common
2091 to str, bytes and bytearray could be optimized away by the compiler, letting
2092 the interpreter segfault instead of raising an error.
2093
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002094- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2095 __next__ method.
2096
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002097- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2098 function no longer attempt to call the __long__ slot to convert an object
2099 to an integer. Only the __int__ and __trunc__ slots are examined.

2104
Antoine Pitrouab868312009-01-10 15:40:25 +00002105- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2106 common cases are optimized thanks to a dedicated fast path and a moderate
2107 amount of loop unrolling.
2108
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002109- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2110 collecting the oldest generation) so that allocating lots of objects without
2111 destroying them does not show quadratic performance. Based on a proposal by
2112 Martin von Löwis at
2113 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2114
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002115- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002116 having been closed (for instance, a read() call could return some
2117 previously buffered data). Patch by Dmitry Vasiliev.
2118
Antoine Pitrou05608432009-01-09 18:53:14 +00002119- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2120 flag to work properly. Furthermore, when specifying -u, the text stdout
2121 and stderr streams have line-by-line buffering enabled (the default being
2122 to buffer arbitrary chunks of data).
2123
Raymond Hettinger35631532009-01-09 03:58:09 +00002124- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2125 instead of ints (reducing its size from 4 to 8 times thereby reducing
2126 Python's overall memory).
2127
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002128- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2129 an existing .py counterpart, override the co_filename attributes of all
2130 code objects if the original filename is obsolete (which can happen if the
2131 file has been renamed, moved, or if it is accessed through different paths).
2132 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2133
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002134- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2135 one byte. Also fixes the meaning of len() so that it returns the number of
2136 items, rather than the size in bytes.
2137
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002138- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2139
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002140- Issue #4747: When the terminal does not use utf-8, executing a script with
2141 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2142

2147 did not get collected.
2148
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002149- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2150 where the tp_hash and tp_dict slots are both NULL.
2151
Georg Brandlccc47b62008-12-28 11:44:14 +00002152- Issue #4759: None is now allowed as the first argument of
2153 bytearray.translate(). It was always allowed for bytes.translate().
2154
Skip Montanaro80072cb2008-12-23 03:51:14 +00002155- Added test case to ensure attempts to read from a file opened for writing
2156 fail.

2162
Antoine Pitrou621601a2008-12-17 23:18:19 +00002163- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2168
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002169- Issue #2173: When getting device encoding, check that return value of
2170 nl_langinfo is not the empty string. This was causing silent build
2171 failures on OS X.
2172
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002173- Issue #4597: Fixed several opcodes that weren't always propagating
2174 exceptions.
2175
2176- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002177 context manager returns a value that cannot be converted to a bool.
2178
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002179- Issue #4445: Replace "sizeof(PyBytesObject)" with
2180 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2181 bytes instances. On a typical machine this saves 3 bytes of memory
2182 (on average) per allocation of a bytes instance.
2183
Christian Heimesa872de52008-12-05 08:26:55 +00002184- Issue #4533: File read operation was dreadfully slow due to a slowly
2185 growing read buffer. Fixed by using the same growth rate algorithm as
2186 Python 2.x.
2187
Antoine Pitrou5504e892008-12-06 21:27:53 +00002188- Issue #4509: Various issues surrounding resize of bytearray objects to
2189 which there are buffer exports (e.g. memoryview instances).
2190
Georg Brandlf9734072008-12-07 15:30:06 +00002191- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2192 method on file objects with closefd=False. The file descriptor is still
2193 kept open but the file object behaves like a closed file. The ``FileIO``
2194 object also got a new readonly attribute ``closefd``.

2202
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002203- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2204 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2205 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2206 of using the replace error handler in PyUnicode_DecodeUTF8().
