Victor Stinner372ac5e2010-05-17 01:26:01 +000015- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
16 (instead of strict) error handler to escape surrogates
17
Victor Stinnerae6265f2010-05-15 16:27:27 +000018- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
19 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000020 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
21 back to UTF-8.

Victor Stinnerb744ba12010-05-15 12:27:16 +000026- Issue #8610: Load file system codec at startup, and display a fatal error on
27 failure. Set the file system encoding to utf-8 (instead of None) if getting
28 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
29
Victor Stinner0964ee12010-04-30 16:48:45 +000030- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
31 PyUnicode_FromString() to support surrogates in the filename and use the
32 right encoding
33
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000034- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler

37 arguments.
38
Victor Stinner14284c22010-04-23 12:02:30 +000039- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
40 indirectly Python signal handlers anymore because mywrite() ignores
41 exceptions (KeyboardInterrupt)
42
Victor Stinner31be90b2010-04-22 19:38:16 +000043- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing

47 you have to convert your bytearray filenames to bytes
48
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000049- Issue #7332: Remove the 16KB stack-based buffer in
50 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
51 benefit compared to the dynamic memory allocation fallback. Patch by
52 Charles-François Natali.
53
Benjamin Peterson8380dd52010-04-16 22:51:37 +000054- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
55 passed to bytes or bytearray.
56
Philip Jenvey0805ca32010-04-07 04:04:10 +000057- Issue #7301: Add environment variable $PYTHONWARNINGS.
58
Benjamin Petersond856ab62010-04-06 21:55:16 +000059- Issue #8329: Don't return the same lists from select.select when no fds are
60 changed.
61
Mark Dickinson3318d292010-04-06 16:53:17 +000062- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
63 on 64-bit machines. The shift count for either left or right shift is
64 permitted to be up to sys.maxsize.
65
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000066- Ensure that tokenization of identifiers is not affected by locale.

79
Mark Dickinsond59b4162010-03-13 11:34:40 +000080- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
81 PyMemberDefs could produce an internal error; raise TypeError instead.
82
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000083- Issue #7845: Rich comparison methods on the complex type now return
84 NotImplemented rather than raising a TypeError when comparing with an
85 incompatible type; this allows user-defined classes to implement their own
86 comparisons with complex.
87
Victor Stinner52f6dd72010-03-12 14:45:56 +000088- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt

117 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
118 and PyOS_string_to_double instead. See issue #5835 for the original
119 deprecations.
120
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000121- Issue #7385: Fix a crash in `MemoryView_FromObject` when
122 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
123
Mark Dickinsonbc099642010-01-29 17:27:24 +0000124- Issue #7788: Fix an interpreter crash produced by deleting a list
125 slice with very large step value.
126
Eric Smithf7bb5782010-01-27 00:44:57 +0000127- Issue #7766: Change sys.getwindowsversion() return value to a named
128 tuple and add the additional members returned in an OSVERSIONINFOEX
129 structure. The new members are service_pack_major, service_pack_minor,
130 suite_mask, and product_type.
131
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000132- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
133 could crash in many places because of the PyByteArray_AS_STRING() macro
134 returning NULL. The macro now returns a statically allocated empty
135 string instead.
136
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000137- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
138 where the right hand operand is a set of constants, by turning the set into
139 a frozenset and pre-building it as a constant. The comparison operation
140 is made against the constant instead of building a new set each time it is
141 executed (a similar optimization already existed which turned a list of
142 constants into a pre-built tuple). Patch and additional tests by Dave
143 Malcolm.
144
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000145- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

150 alpha 2, including: (1) a serious 'wrong output' bug that could
151 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
152 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000153 strings corresponding to subnormal values, (3) a memory leak for
154 some values large enough to cause overflow, and (4) a number of
155 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000156
Benjamin Petersonaea44282010-01-04 01:10:28 +0000157- The __complex__ method is now looked up on the class of instances to make it

168 described in C99 Annex F.
169
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000170- Issue #1811: improve accuracy and cross-platform consistency for
171 true division of integers: the result of a/b is now correctly
172 rounded for ints a and b (at least on IEEE 754 platforms), and in
173 particular does not depend on the internal representation of an int.
174
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000175- Issue #6834: replace the implementation for the 'python' and 'pythonw'
176 executables on OSX.
177
178 These executables now work properly with the arch(1) command:
179 ``arch -ppc python`` will start a universal binary version of python
180 in PPC mode (unlike previous releases).
181
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000182- Issue #7466: segmentation fault when the garbage collector is called

Mark Dickinsond550c9a2009-11-15 09:57:26 +0000199- Issue #7298: fixes for range and reversed(range(...)). Iteration
200 over range(a, b, c) incorrectly gave an empty iterator when a, b and
201 c fit in C long but the length of the range did not. Also fix

313-----
314
Benjamin Petersonfb886362010-04-24 18:21:17 +0000315- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
316 strings in an efficient manner.
317
Antoine Pitrou8689a102010-04-01 16:53:15 +0000318- Issue #8276: PyEval_CallObject() is now only available in macro form. The
319 function declaration, which was kept for backwards compatibility reasons,
320 is now removed (the macro was introduced in 1997!).
321
Mark Dickinson93f562c2010-01-30 10:30:15 +0000322- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
323 analogous to PyLong_AsLongAndOverflow.
324
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000325- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
326 has '\0' at the end.
327
Mark Dickinsonde604012010-01-01 19:27:32 +0000328- Issue #5080: The argument parsing functions PyArg_ParseTuple,
329 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
330 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
331 DeprecationWarning for float arguments passed with the 'L' format
332 code. This will become a TypeError in a future version of Python,
333 to match the behaviour of the other integer format codes.
334
Georg Brandl1e28a272009-12-28 08:41:01 +0000335- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
336
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000337- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
338 in PyArg_ParseTupleAndKeywords.
339
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000340- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)
Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000341 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
342
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000343- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
344 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
345 should used for accessing the d_type and d_name members of structures
346 using PyDescr_COMMON.
347
348- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000349
Benjamin Peterson466a7822009-07-02 21:44:01 +0000350- The code flags for old __future__ features are now available again.
351
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000352- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
353 PyCode_Addr2Line().
354
355- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
356 object at a specified file, function, and line number.
357
358- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
359 ``const char *`` as the string is stored beyond the call.
360
Benjamin Peterson05159c42009-12-03 03:01:27 +0000361- Issue #2422: When compiled with the ``--with-valgrind`` option, the
362 pymalloc allocator will be automatically disabled when running under
363 Valgrind. This gives improved memory leak detection when running
364 under Valgrind, while taking advantage of pymalloc at other times.

Victor Stinnerf9faaad2010-05-16 21:36:37 +0000369- Issue #8477: ssl.RAND_egd() and ssl._test_decode_cert() support str with
370 surrogates and bytes for the filename
Victor Stinner3800e1e2010-05-16 21:23:48 +0000371
Antoine Pitrou152efa22010-05-16 18:19:27 +0000372- Issue #8550: Add first class ``SSLContext`` objects to the ssl module.
373
Antoine Pitrou53b21662010-05-11 23:46:02 +0000374- Issue #8681: Make the zlib module's error messages more informative when
375 the zlib itself doesn't give any detailed explanation.
376
Mark Dickinson81fece22010-05-11 13:34:35 +0000377- The audioop module now supports sound fragments of length greater
378 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
379
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000380- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
381 class.
382
Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000383- Issue #8664: In py_compile, create __pycache__ when the compiled path is
384 given.
385
Victor Stinner449c4662010-05-08 11:10:09 +0000386- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
387 for use in the file system, environment variables or the command line.
388
Antoine Pitrou89562712010-05-07 17:04:02 +0000389- Issue #8571: Fix an internal error when compressing or decompressing a

391 objects.
392
Benjamin Peterson225168e2010-05-06 22:29:53 +0000393- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
394 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
395 file system encoding with the surrogateescape error handler (instead of
396 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000397
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000398- Issue #8573: asyncore _strerror() function might throw ValueError.
399
Victor Stinnere125f132010-05-15 21:04:43 +0000400- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
401 error messages when accessing undefined class attributes because of the cheap
402 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000403 The cheap inheritance has been deprecated.
404
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000405- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
406 Patch by Tres Seaver.
407
Victor Stinnerde629d42010-05-05 21:43:57 +0000408- Issue #8390: tarfile uses surrogateespace as the default error handler
409 (instead of replace in read mode or strict in write mode)
410
Barry Warsaw83d89982010-05-05 16:18:31 +0000411- Issue #7755: Use an unencumbered audio file for tests.
412
Ronald Oussorenac764d32010-05-05 15:32:33 +0000413- Issue #8621: uuid.uuid4() returned the same sequence of values in the

415
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000416- Issue #8567: Fix precedence of signals in Decimal module: when a
417 Decimal operation raises multiple signals and more than one of those
418 signals is trapped, the specification determines the order in which
419 the signals should be handled. In many cases this order wasn't
420 being followed, leading to the wrong Python exception being raised.
421
Antoine Pitrou6be88762010-05-03 16:48:20 +0000422- Issue #7865: The close() method of :mod:`io` objects should not swallow
423 exceptions raised by the implicit flush(). Also ensure that calling
424 close() several times is supported. Patch by Pascal Chambon.
425
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000426- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
427 gc.DEBUG_STATS.
428
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000429- Issue #8354: The siginterrupt setting is now preserved for all signals,
430 not just SIGCHLD.
431
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000432- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
433 webbrowser.get("safari").
434
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000435- Issue #8464: tarfile no longer creates files with execute permissions set
436 when mode="w|" is used.
437
Antoine Pitroubf043492010-04-29 10:11:46 +0000438- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
439 of the Linux kernel. Patch by Yaniv Aknin.
440
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000441- Issue #8295: Added shutil.unpack_archive.

Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000443- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
444 It should correctly return an empty response now.
445
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000446- Issue #8546: Reject None given as the buffering argument to _pyio.open.

450
R. David Murrayad78d152010-04-27 02:45:53 +0000451- Issue #6656: fix locale.format_string to handle escaped percents
452 and mappings.
453
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000454- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
455 where the method could block indefinitely if called just before the
456 event loop started running. This also fixes the occasional freezes
457 witnessed in test_httpservers.
458
Antoine Pitrou40f08742010-04-24 22:04:40 +0000459- Issue #8524: When creating an SSL socket, the timeout value of the
460 original socket wasn't retained (instead, a socket with a positive timeout
461 would be turned into a non-blocking SSL socket).
462
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000463- Issue #5103: SSL handshake would ignore the socket timeout and block
464 indefinitely if the other end didn't respond.
465
466- The do_handshake() method of SSL objects now adjusts the blocking mode of
467 the SSL structure if necessary (as other methods already do).
468
Victor Stinner13bb71c2010-04-23 21:41:56 +0000469- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
470 and bytes strings for environment keys and values
471
Victor Stinner4d078042010-04-23 19:28:32 +0000472- Issue #8467: Pure Python implementation of subprocess encodes the error
473 message using surrogatepass error handler to support surrogates in the
474 message
475
Victor Stinner349fd522010-04-23 10:56:17 +0000476- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
477
Sean Reifscheider13daf122010-04-23 09:29:52 +0000478- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
479 the string "python" as the *ident*. openlog() arguments are all optional
480 and keywords.
481
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000482- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
483 a non-infinite timeout. Also make that method friendlier with applications
484 wanting to continue using the socket in clear-text mode, by disabling
485 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
486
Antoine Pitrou7062db82010-04-22 13:30:10 +0000487- Issue #8496: make mailcap.lookup() always return a list, rather than an
488 iterator. Patch by Gregory Nofi.
489
Victor Stinner35466c52010-04-22 11:23:23 +0000490- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
491 collation name contains a surrogate character.
492
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000493- Issue #8484: Load all ciphers and digest algorithms when initializing
494 the _ssl extension, such that verification of some SSL certificates
495 doesn't fail because of an "unknown algorithm".
496
Tarek Ziadéfb437512010-04-20 08:57:33 +0000497- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
498
Victor Stinnere125f132010-05-15 21:04:43 +0000499- Issue #1540112: Now allowing the choice of a copy function in

501
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000502- Issue #4814: timeout parameter is now applied also for connections resulting
503 from PORT/EPRT commands.
504
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000505- Issue #8463: added missing reference to bztar in shutil's documentation.
506
Ronald Oussoren84151202010-04-18 20:46:11 +0000507- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
508 (as long as the user didn't specify 'automatic proxy configuration').
509
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000510- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
511 code as stated in RFC-959 at chapter 5.4.
512
Victor Stinner738446f02010-04-18 00:00:44 +0000513- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
514 surrogates.
515
Antoine Pitrou0454af92010-04-17 23:51:58 +0000516- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000517 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000519- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
520 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
521
Victor Stinner0e59cc32010-04-16 23:49:32 +0000522- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
523 the current working directory.
524
Victor Stinner5bfe1462010-04-16 13:28:05 +0000525- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
526 using backslashreplace error handler
527
Victor Stinnercfa72782010-04-16 11:45:13 +0000528- Issue #8412: os.system() now accepts bytes, bytearray and str with

535
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000536- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
537 module now takes an optional timeout argument in seconds. Timeout support
538 relies on the system threading library, so as to avoid a semi-busy wait
539 loop.
540
Victor Stinner485fb562010-04-13 11:07:24 +0000541- Issue #8383: pickle and pickletools use surrogatepass error handler when
542 encoding unicode as utf8 to support lone surrogates and stay compatible with
543 Python 2.x and 3.0
544
R. David Murrayb2416e52010-04-12 16:58:02 +0000545- Issue #7585: difflib context and unified diffs now place a tab between
546 filename and date, conforming to the 'standards' they were originally
547 designed to follow. This improves compatibility with patch tools.
548
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000549- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
550 character sets will now consistently use a Content-Transfer-Encoding of
551 7bit rather than sometimes being marked as 8bit.
552
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000553- Issue #8375: test_distutils now checks if the temporary directory are still
554 present before it cleans them.
555
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000556- Issue #8374: Update the internal alias table in the :mod:`locale` module
557 to cover recent locale changes and additions.
558
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000559- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
560 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
561 and `ssl.OPENSSL_VERSION_NUMBER`.
562
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000563- Add functools.total_ordering() and functools.cmp_to_key().
564
Mark Dickinson089b00c2010-04-03 15:51:03 +0000565- Issue #8257: The Decimal construct now accepts a float instance
566 directly, converting that float to a Decimal of equal value:
567
568 >>> Decimal(1.1)
569 Decimal('1.100000000000000088817841970012523233890533447265625')
570
Mark Dickinson98127c32010-04-03 11:18:52 +0000571- Issue #8294: The Fraction constructor now accepts Decimal and float
572 instances directly.
573
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000574- Issue #7279: Comparisons involving a Decimal signaling NaN now
575 signal InvalidOperation instead of returning False. (Comparisons
576 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
577 are now hashable; Decimal signaling NaNs remain unhashable.
578
579- Issue #2531: Comparison operations between floats and Decimal
580 instances now return a result based on the numeric values of the
581 operands; previously they returned an arbitrary result based on
582 the relative ordering of id(float) and id(Decimal).
583
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000584- Added a subtract() method to collections.Counter().
585
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000586- Issue #8233: When run as a script, py_compile.py optionally takes a single
587 argument `-` which tells it to read files to compile from stdin. Each line
588 is read on demand and the named file is compiled immediately. (Original
589 patch by Piotr Ożarowski).
590
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000591- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
592 form feed (0x0C) are now considered linebreaks, as specified in Unicode
593 Standard Annex #14. See issue #7643.
594 http://www.unicode.org/reports/tr14/
595
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000596- Comparisons using one of <, <=, >, >= between a complex instance and
597 a Fractions instance now raise TypeError instead of returning
598 True/False. This makes Fraction <=> complex comparisons consistent with
599 int <=> complex, float <=> complex, and complex <=> complex comparisons.
600
Antoine Pitrou39b35432010-03-23 00:25:54 +0000601- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
602 some methods (such as oss_mixer_device.fileno()) were not available.
603 Initial patch by Bertrand Janin.
604
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000605- Issue #8205: Remove the "Modules" directory from sys.path when Python is
606 running from the build directory (POSIX only).
607
Antoine Pitrou910bd512010-03-22 20:11:09 +0000608- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
609 didn't support chflags() (for example ZFS under FreeBSD). The error is
610 now silenced.
611
R. David Murrayca2edce2010-03-22 17:48:48 +0000612- Issue #7860: platform.uname now reports the correct 'machine' type

908
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000909- Issue #6816: runpy now provides a run_path function that allows Python code
910 to execute file paths that refer to source or compiled Python files as well
911 as zipfiles, directories and other valid sys.path entries that contain a
912 __main__.py file. This allows applications that run other Python scripts to
913 support the same flexibility as the CPython command line itself.
914
Antoine Pitrou45d61a32009-11-13 22:35:18 +0000915- Issue #7318: multiprocessing now uses a timeout when it fails to establish
916 a connection with another process, rather than looping endlessly. The
917 default timeout is 20 seconds, which should be amply sufficient for
918 local connections.
919
Antoine Pitrouc63ecee2009-11-10 21:34:48 +0000920- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and

922 test_multiprocessing in verbose mode.
923
Michael Foord34c94622010-02-10 15:51:42 +0000924- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
925 argument added to the TextTestRunner constructor allowing a different result
926 class to be used without having to subclass.

Victor Stinnere125f132010-05-15 21:04:43 +0000932 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +0000933 recursive locks as fast as regular non-recursive locks (previously,
934 they were slower by 10x to 15x).
935
Antoine Pitroub0872682009-11-09 16:08:16 +0000936- Issue #7282: Fix a memory leak when an RLock was used in a thread other

950 a modification is done through it. This fixes inconsistencies and test
951 failures on systems with slightly bogus mtime behaviour.
952
Gregory P. Smith50467882009-11-01 18:42:17 +0000953- Issue #7246 & Issue #7208: getpass now properly flushes input before
954 reading from stdin so that existing input does not confuse it and
955 lead to incorrect entry or an IOError. It also properly flushes it
956 afterwards to avoid the terminal echoing the input afterwards on
957 OSes such as Solaris.
958
Mark Dickinsona2d1fe02009-10-29 12:23:02 +0000959- Issue #7233: Fix a number of two-argument Decimal methods to make

990 anachronisms in the code which were a relic of 1.5.2 compatibility.
Vinay Sajip96d4aa32009-10-16 14:06:44 +0000991
R. David Murraybf2e0aa2009-10-10 00:13:32 +0000992- Issue #7082: When falling back to the MIME 'name' parameter, the

1220 gcc. (Optimization was unintentionally turned on in gcc

Antoine Pitrou65c9c642009-10-30 17:25:12 +00001406- Issue #7222: Make thread "reaping" more reliable so that reference
1407 leak-chasing test runs give sensible results. The previous method of
1408 reaping threads could return successfully while some Thread objects were
1409 still referenced. This also introduces a new private function:
1410 :func:`_thread._count()`.

1414
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001415- Issue #7055: test___all__ now greedily detects all modules which have an
1416 __all__ attribute, rather than using a hardcoded and incomplete list.

1420 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001421
Mark Dickinson2e304402009-10-04 18:43:54 +00001422- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1423

1425 the proper exceptions that should be raised for missing or improper code
1426 object bytecode.

1592 was locale aware; and (3) the interpretation of fromhex('-nan')
1593 didn't match that of float('-nan').

1616
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001617- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1618 than an int, which makes some operations possible under 64-bit Linux (e.g.
1619 DN_MULTISHOT with F_NOTIFY).
1620
Antoine Pitrou716c4442009-05-23 19:04:03 +00001621- Issue #5761: Add the name of the underlying file to the repr() of various

Mark Dickinson865e01a2009-05-07 16:37:01 +00001699- Issue #5914: Add new C API function PyOS_string_to_double, and
1700 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1701
Eric Smith741191f2009-05-06 13:08:15 +00001702- Issue #3382: float.__format__, complex.__format__, and %-formatting
1703 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1704 affects nan -> NAN and inf -> INF.
1705
Mark Hammond5a607a32009-05-06 08:04:54 +00001706- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1707 in all operations, including splitdrive, split, etc. splitunc() now issues
1708 a PendingDeprecation warning.

Eric Smith63376222009-05-05 14:04:18 +00001710- Issue #5920: For float.__format__, change the behavior with the
1711 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1712 to be like 'g' but with at least one decimal point and with a
1713 default precision of 12. Previously, the behavior the same but with
1714 a default precision of 6. This more closely matches str(), and
1715 reduces surprises when adding alignment flags to the empty
1716 presentation type. This also affects the new complex.__format__ in
1717 the same way.
1718
Martin v. Löwis011e8422009-05-05 04:43:17 +00001719- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001730- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1731 received a new method, detach(). detach() disconnects the underlying stream
1732 from the buffer or text IO and returns it.
1733
Mark Dickinson33841c32009-05-01 15:37:04 +00001734- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1735 floats with absolute value over 1e50. Also remove length
1736 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1737 12.34 no longer raise an exception.

1743 never gives more than the requested number of significant digits.
1744
Eric Smith6dc46f52009-04-27 20:39:49 +00001745- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1756 z involves nans, infs or negative zeros.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00001760- Issue #1869 (and many duplicates): make round(x, n) correctly
1761 rounded for a float x, by using the decimal <-> binary conversions
1762 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1763 consistently agrees with format(x, '.2f').

Benjamin Petersonae937c02009-04-18 20:54:08 +00001765- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1766 some builtin types.
1767
Eric Smith0923d1d2009-04-16 20:16:10 +00001768- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1769
Eric Smith35e84722009-04-16 20:21:28 +00001770- Issue #5515: str.format() type 'n' combined with commas and leading
1771 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001772
1773- Implement PEP 378, Format Specifier for Thousands Separator, for
1774 floats.
1775
Mark Dickinson3370cce2009-04-17 22:40:53 +00001776- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001777 1e11, not 1e12. This avoids printing 13 significant digits in
1778 situations where only 12 of them are correct. Example problem
1779 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1780 long time.)
1781
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001782- Issue #1580: On most platforms, use a 'short' float repr: for a
1783 finite float x, repr(x) now outputs a string based on the shortest
1784 sequence of decimal digits that rounds to x. Previous behaviour was
1785 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001786 Another minor difference is that the new repr switches to
1787 exponential notation at 1e16 instead of the previous 1e17; this
1788 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001789
1790 There's a new sys attribute sys.float_repr_style, which takes
1791 the value 'short' to indicate that we're using short float repr,
1792 and 'legacy' if the short float repr isn't available for one
1793 reason or another.
1794
1795 The float repr change involves incorporating David Gay's 'perfect
1796 rounding' code into the Python core (it's in Python/dtoa.c). As a
1797 secondary consequence, all string-to-float and float-to-string
1798 conversions (including all float formatting operations) will be
1799 correctly rounded on these platforms.
1800
1801 See issue 1580 discussions for details of platforms for which
1802 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001804- Issue #5759: float() didn't call __float__ on str subclasses.
1805
Georg Brandlabc38772009-04-12 15:51:51 +00001806- The string.maketrans() function is deprecated; there is a new static method
1807 maketrans() on the bytes and bytearray classes. This removes confusion about
1808 the types string.maketrans() is supposed to work with, and mirrors the
1809 methods available on the str class.

1976 untrackable objects are not tracked by the garbage collector. This can
1977 reduce the size of collections and therefore the garbage collection overhead
1978 on long-running programs, depending on their particular use of datatypes.

Mark Dickinsonae681df2009-03-21 10:26:31 +00002070- Issue #5463: In struct module, remove deprecated overflow wrapping
2071 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002072 struct.error instead of returning b'\xff\xff\xff\xff'. The
2073 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2074 have been removed from the struct module.

2099 rotating the object pointer by 4 bits to the right.
2100
Mark Dickinson87ec0852009-02-09 17:15:59 +00002101- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2102 it now forces its argument to double before testing for infinity.
2103
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002104- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002113
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002114- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002115 were suppressing all exceptions. These include list() and bytearray().

2119
Antoine Pitroub52ec782009-01-25 16:34:23 +00002120- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2121 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2122 evaluation loop is compiled with a new dispatch mechanism which gives
2123 speedups of up to 20%, depending on the system, on various benchmarks.
2124
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002125- Issue #4874: Most builtin decoders now reject unicode input.

2131
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002132- Issue #4838: When a module is deallocated, free the memory backing the
2133 optional module state data.
2134
Mark Dickinson8055afd2009-01-17 10:04:45 +00002135- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2136 type to (void *).
2137
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002138- Issue #4935: The overflow checking code in the expandtabs() method common
2139 to str, bytes and bytearray could be optimized away by the compiler, letting
2140 the interpreter segfault instead of raising an error.
2141
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002142- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2143 __next__ method.
2144
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002145- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2146 function no longer attempt to call the __long__ slot to convert an object
2147 to an integer. Only the __int__ and __trunc__ slots are examined.
2148
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002149- Issue #4893: Use NT threading on CE.
2150

2152
Antoine Pitrouab868312009-01-10 15:40:25 +00002153- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2154 common cases are optimized thanks to a dedicated fast path and a moderate
2155 amount of loop unrolling.
2156
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002157- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2158 collecting the oldest generation) so that allocating lots of objects without
2159 destroying them does not show quadratic performance. Based on a proposal by
2160 Martin von Löwis at
2161 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2162
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002163- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002164 having been closed (for instance, a read() call could return some
2165 previously buffered data). Patch by Dmitry Vasiliev.
2166
Antoine Pitrou05608432009-01-09 18:53:14 +00002167- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2168 flag to work properly. Furthermore, when specifying -u, the text stdout
2169 and stderr streams have line-by-line buffering enabled (the default being
2170 to buffer arbitrary chunks of data).
2171
Raymond Hettinger35631532009-01-09 03:58:09 +00002172- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2173 instead of ints (reducing its size from 4 to 8 times thereby reducing
2174 Python's overall memory).
2175
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002176- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2177 an existing .py counterpart, override the co_filename attributes of all
2178 code objects if the original filename is obsolete (which can happen if the
2179 file has been renamed, moved, or if it is accessed through different paths).
2180 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2181
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002182- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2183 one byte. Also fixes the meaning of len() so that it returns the number of
2184 items, rather than the size in bytes.
2185
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002186- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2187
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002188- Issue #4747: When the terminal does not use utf-8, executing a script with
2189 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2190
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002191- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002192 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002193
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002194- Issue #3680: Reference cycles created through a dict, set or deque iterator
2195 did not get collected.
2196
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002197- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2198 where the tp_hash and tp_dict slots are both NULL.
2199
Georg Brandlccc47b62008-12-28 11:44:14 +00002200- Issue #4759: None is now allowed as the first argument of
2201 bytearray.translate(). It was always allowed for bytes.translate().
2202
Skip Montanaro80072cb2008-12-23 03:51:14 +00002203- Added test case to ensure attempts to read from a file opened for writing
2204 fail.
2205
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002206- Issue #3106: Speedup some comparisons (str/str and int/int).

2210
Antoine Pitrou621601a2008-12-17 23:18:19 +00002211- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2212 print elapsed times, not only when some objects are uncollectable /
2213 unreachable. Original patch by Neil Schemenauer.
2214
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002215- Issue #3439: Add a bit_length method to int.
2216
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002217- Issue #2173: When getting device encoding, check that return value of
2218 nl_langinfo is not the empty string. This was causing silent build
2219 failures on OS X.
2220
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002221- Issue #4597: Fixed several opcodes that weren't always propagating
2222 exceptions.
2223
2224- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002225 context manager returns a value that cannot be converted to a bool.
2226
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002227- Issue #4445: Replace "sizeof(PyBytesObject)" with
2228 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2229 bytes instances. On a typical machine this saves 3 bytes of memory
2230 (on average) per allocation of a bytes instance.
2231
Christian Heimesa872de52008-12-05 08:26:55 +00002232- Issue #4533: File read operation was dreadfully slow due to a slowly
2233 growing read buffer. Fixed by using the same growth rate algorithm as
2234 Python 2.x.
2235
Antoine Pitrou5504e892008-12-06 21:27:53 +00002236- Issue #4509: Various issues surrounding resize of bytearray objects to
2237 which there are buffer exports (e.g. memoryview instances).
2238
Georg Brandlf9734072008-12-07 15:30:06 +00002239- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2240 method on file objects with closefd=False. The file descriptor is still
2241 kept open but the file object behaves like a closed file. The ``FileIO``
2242 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002243
Antoine Pitroubc420402008-12-07 20:14:49 +00002244- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2245 larger than 1.

2250
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002251- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2252 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2253 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2254 of using the replace error handler in PyUnicode_DecodeUTF8().
