Victor Stinnerae6265f2010-05-15 16:27:27 +000015- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
16 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000017 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
18 back to UTF-8.

24 failure. Set the file system encoding to utf-8 (instead of None) if getting
25 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
26
Victor Stinner0964ee12010-04-30 16:48:45 +000027- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
28 PyUnicode_FromString() to support surrogates in the filename and use the
29 right encoding
30

44 you have to convert your bytearray filenames to bytes
45
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000046- Issue #7332: Remove the 16KB stack-based buffer in
47 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
48 benefit compared to the dynamic memory allocation fallback. Patch by
49 Charles-François Natali.
50
Benjamin Peterson8380dd52010-04-16 22:51:37 +000051- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
52 passed to bytes or bytearray.
53

60 on 64-bit machines. The shift count for either left or right shift is
61 permitted to be up to sys.maxsize.
62
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000063- Ensure that tokenization of identifiers is not affected by locale.

79
Mark Dickinsonf673f0c2010-03-13 09:48:39 +000080- Issue #7845: Rich comparison methods on the complex type now return
81 NotImplemented rather than raising a TypeError when comparing with an
82 incompatible type; this allows user-defined classes to implement their own
83 comparisons with complex.
84
Victor Stinner52f6dd72010-03-12 14:45:56 +000085- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt

114 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
115 and PyOS_string_to_double instead. See issue #5835 for the original
116 deprecations.
117
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000118- Issue #7385: Fix a crash in `MemoryView_FromObject` when
119 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
120
Mark Dickinsonbc099642010-01-29 17:27:24 +0000121- Issue #7788: Fix an interpreter crash produced by deleting a list
122 slice with very large step value.
123
Eric Smithf7bb5782010-01-27 00:44:57 +0000124- Issue #7766: Change sys.getwindowsversion() return value to a named
125 tuple and add the additional members returned in an OSVERSIONINFOEX
126 structure. The new members are service_pack_major, service_pack_minor,

128
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000129- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
130 could crash in many places because of the PyByteArray_AS_STRING() macro
131 returning NULL. The macro now returns a statically allocated empty
132 string instead.
133
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000134- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
135 where the right hand operand is a set of constants, by turning the set into
136 a frozenset and pre-building it as a constant. The comparison operation
137 is made against the constant instead of building a new set each time it is
138 executed (a similar optimization already existed which turned a list of
139 constants into a pre-built tuple). Patch and additional tests by Dave
140 Malcolm.
141
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000142- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
143 methods of bytes, bytearray and unicode objects by using a common
144 implementation based on stringlib's fast search. Patch by Florent Xicluna.

147 alpha 2, including: (1) a serious 'wrong output' bug that could
148 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
149 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000150 strings corresponding to subnormal values, (3) a memory leak for
151 some values large enough to cause overflow, and (4) a number of
152 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000153
Benjamin Petersonaea44282010-01-04 01:10:28 +0000154- The __complex__ method is now looked up on the class of instances to make it

165 described in C99 Annex F.
166
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000167- Issue #1811: improve accuracy and cross-platform consistency for
168 true division of integers: the result of a/b is now correctly
169 rounded for ints a and b (at least on IEEE 754 platforms), and in
170 particular does not depend on the internal representation of an int.
171
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000172- Issue #6834: replace the implementation for the 'python' and 'pythonw'
173 executables on OSX.
174

Mark Dickinsond550c9a2009-11-15 09:57:26 +0000196- Issue #7298: fixes for range and reversed(range(...)). Iteration
197 over range(a, b, c) incorrectly gave an empty iterator when a, b and
198 c fit in C long but the length of the range did not. Also fix

310-----
311
Benjamin Petersonfb886362010-04-24 18:21:17 +0000312- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are
313 strings in an efficient manner.
314
Antoine Pitrou8689a102010-04-01 16:53:15 +0000315- Issue #8276: PyEval_CallObject() is now only available in macro form. The
316 function declaration, which was kept for backwards compatibility reasons,
317 is now removed (the macro was introduced in 1997!).
318
Mark Dickinson93f562c2010-01-30 10:30:15 +0000319- Issue #7767: New function PyLong_AsLongLongAndOverflow added,
320 analogous to PyLong_AsLongAndOverflow.
321
Benjamin Peterson8667a9b2010-01-09 21:45:28 +0000322- Make PyUnicode_CompareWithASCIIString return not equal if the Python string
323 has '\0' at the end.
324
Mark Dickinsonde604012010-01-01 19:27:32 +0000325- Issue #5080: The argument parsing functions PyArg_ParseTuple,
326 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
327 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
328 DeprecationWarning for float arguments passed with the 'L' format
329 code. This will become a TypeError in a future version of Python,
330 to match the behaviour of the other integer format codes.
331
Georg Brandl1e28a272009-12-28 08:41:01 +0000332- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.
333
Mark Dickinsonf08173b2009-12-03 10:59:46 +0000334- Issue #7414: 'C' code wasn't being skipped properly (for keyword arguments)
335 in PyArg_ParseTupleAndKeywords.
336
Mark Dickinson0b2b2322009-12-04 11:32:26 +0000337- Issue #7228: Add '%lld' and '%llu' support to PyString_FromFormat(V)
Mark Dickinson6ce4a9a2009-11-16 17:00:11 +0000338 and PyErr_Format, on machines with HAVE_LONG_LONG defined.
339
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000340- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
341 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
342 should used for accessing the d_type and d_name members of structures
343 using PyDescr_COMMON.
344
345- Issue #6405: Remove duplicate type declarations in descrobject.h.
Benjamin Peterson89b89172009-07-03 13:30:25 +0000346
Benjamin Peterson466a7822009-07-02 21:44:01 +0000347- The code flags for old __future__ features are now available again.
348
Alexandre Vassalotti7b82b402009-07-21 04:30:03 +0000349- Issue #5954: Add a PyFrame_GetLineNumber() function to replace most uses of
350 PyCode_Addr2Line().
351
352- Issue #5959: Add a PyCode_NewEmpty() function to create a new empty code
353 object at a specified file, function, and line number.
354
355- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
356 ``const char *`` as the string is stored beyond the call.
357
Benjamin Peterson05159c42009-12-03 03:01:27 +0000358- Issue #2422: When compiled with the ``--with-valgrind`` option, the
359 pymalloc allocator will be automatically disabled when running under
360 Valgrind. This gives improved memory leak detection when running
361 under Valgrind, while taking advantage of pymalloc at other times.

367
Antoine Pitrou53b21662010-05-11 23:46:02 +0000368- Issue #8681: Make the zlib module's error messages more informative when
369 the zlib itself doesn't give any detailed explanation.
370
Mark Dickinson81fece22010-05-11 13:34:35 +0000371- The audioop module now supports sound fragments of length greater
372 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
373
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000374- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
375 class.
376
Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000377- Issue #8664: In py_compile, create __pycache__ when the compiled path is
378 given.
379
Victor Stinner449c4662010-05-08 11:10:09 +0000380- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
381 for use in the file system, environment variables or the command line.
382
Antoine Pitrou89562712010-05-07 17:04:02 +0000383- Issue #8571: Fix an internal error when compressing or decompressing a
384 chunk larger than 1GB with the zlib module's compressor and decompressor
385 objects.
386
Benjamin Peterson225168e2010-05-06 22:29:53 +0000387- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
388 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
389 file system encoding with the surrogateescape error handler (instead of
390 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000391
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000392- Issue #8573: asyncore _strerror() function might throw ValueError.
393
Victor Stinnere125f132010-05-15 21:04:43 +0000394- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
395 error messages when accessing undefined class attributes because of the cheap
396 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000397 The cheap inheritance has been deprecated.
398
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000399- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
400 Patch by Tres Seaver.
401
Victor Stinnerde629d42010-05-05 21:43:57 +0000402- Issue #8390: tarfile uses surrogateespace as the default error handler
403 (instead of replace in read mode or strict in write mode)
404
Barry Warsaw83d89982010-05-05 16:18:31 +0000405- Issue #7755: Use an unencumbered audio file for tests.
406
Ronald Oussorenac764d32010-05-05 15:32:33 +0000407- Issue #8621: uuid.uuid4() returned the same sequence of values in the
408 parent and any children created using ``os.fork`` on MacOS X 10.6.
409
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000410- Issue #8567: Fix precedence of signals in Decimal module: when a
411 Decimal operation raises multiple signals and more than one of those
412 signals is trapped, the specification determines the order in which
413 the signals should be handled. In many cases this order wasn't
414 being followed, leading to the wrong Python exception being raised.
415
Antoine Pitrou6be88762010-05-03 16:48:20 +0000416- Issue #7865: The close() method of :mod:`io` objects should not swallow
417 exceptions raised by the implicit flush(). Also ensure that calling
418 close() several times is supported. Patch by Pascal Chambon.
419
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000420- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
421 gc.DEBUG_STATS.
422
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000423- Issue #8354: The siginterrupt setting is now preserved for all signals,
424 not just SIGCHLD.
425
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000426- Issue #7192: webbrowser.get("firefox") now wors on Mac OS X, as does
427 webbrowser.get("safari").
428
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000429- Issue #8464: tarfile no longer creates files with execute permissions set
430 when mode="w|" is used.
431
Antoine Pitroubf043492010-04-29 10:11:46 +0000432- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
433 of the Linux kernel. Patch by Yaniv Aknin.
434
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000435- Issue #8295: Added shutil.unpack_archive.
436
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000437- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
438 It should correctly return an empty response now.
439
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000440- Issue #8546: Reject None given as the buffering argument to _pyio.open.
441
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000442- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
443 Sridhar Ratnakumar.
444
R. David Murrayad78d152010-04-27 02:45:53 +0000445- Issue #6656: fix locale.format_string to handle escaped percents
446 and mappings.
447
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000448- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
449 where the method could block indefinitely if called just before the
450 event loop started running. This also fixes the occasional freezes
451 witnessed in test_httpservers.
452
Antoine Pitrou40f08742010-04-24 22:04:40 +0000453- Issue #8524: When creating an SSL socket, the timeout value of the
454 original socket wasn't retained (instead, a socket with a positive timeout
455 would be turned into a non-blocking SSL socket).
456
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000457- Issue #5103: SSL handshake would ignore the socket timeout and block
458 indefinitely if the other end didn't respond.
459
460- The do_handshake() method of SSL objects now adjusts the blocking mode of
461 the SSL structure if necessary (as other methods already do).
462
Victor Stinner13bb71c2010-04-23 21:41:56 +0000463- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
464 and bytes strings for environment keys and values
465
Victor Stinner4d078042010-04-23 19:28:32 +0000466- Issue #8467: Pure Python implementation of subprocess encodes the error
467 message using surrogatepass error handler to support surrogates in the
468 message
469
Victor Stinner349fd522010-04-23 10:56:17 +0000470- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
471
Sean Reifscheider13daf122010-04-23 09:29:52 +0000472- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
473 the string "python" as the *ident*. openlog() arguments are all optional
474 and keywords.
475
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000476- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
477 a non-infinite timeout. Also make that method friendlier with applications
478 wanting to continue using the socket in clear-text mode, by disabling
479 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
480
Antoine Pitrou7062db82010-04-22 13:30:10 +0000481- Issue #8496: make mailcap.lookup() always return a list, rather than an
482 iterator. Patch by Gregory Nofi.
483
Victor Stinner35466c52010-04-22 11:23:23 +0000484- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
485 collation name contains a surrogate character.
486
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000487- Issue #8484: Load all ciphers and digest algorithms when initializing
488 the _ssl extension, such that verification of some SSL certificates
489 doesn't fail because of an "unknown algorithm".
490
Tarek Ziadéfb437512010-04-20 08:57:33 +0000491- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
492
Victor Stinnere125f132010-05-15 21:04:43 +0000493- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000494 shutil.copytree.
495
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000496- Issue #4814: timeout parameter is now applied also for connections resulting
497 from PORT/EPRT commands.
498
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000499- Issue #8463: added missing reference to bztar in shutil's documentation.
500
Ronald Oussoren84151202010-04-18 20:46:11 +0000501- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
502 (as long as the user didn't specify 'automatic proxy configuration').
503
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000504- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
505 code as stated in RFC-959 at chapter 5.4.
506
Victor Stinner738446f02010-04-18 00:00:44 +0000507- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
508 surrogates.
509
Antoine Pitrou0454af92010-04-17 23:51:58 +0000510- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000511 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000512
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000513- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
514 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
515
Victor Stinner0e59cc32010-04-16 23:49:32 +0000516- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
517 the current working directory.
518
Victor Stinner5bfe1462010-04-16 13:28:05 +0000519- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
520 using backslashreplace error handler
521
Victor Stinnercfa72782010-04-16 11:45:13 +0000522- Issue #8412: os.system() now accepts bytes, bytearray and str with
523 surrogates.
524
Senthil Kumaranad02d232010-04-16 03:02:13 +0000525- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
526 Locke and Hans Ulrich Niedermann.

529
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000530- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
531 module now takes an optional timeout argument in seconds. Timeout support
532 relies on the system threading library, so as to avoid a semi-busy wait
533 loop.
534
Victor Stinner485fb562010-04-13 11:07:24 +0000535- Issue #8383: pickle and pickletools use surrogatepass error handler when
536 encoding unicode as utf8 to support lone surrogates and stay compatible with
537 Python 2.x and 3.0
538
R. David Murrayb2416e52010-04-12 16:58:02 +0000539- Issue #7585: difflib context and unified diffs now place a tab between
540 filename and date, conforming to the 'standards' they were originally
541 designed to follow. This improves compatibility with patch tools.
542
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000543- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
544 character sets will now consistently use a Content-Transfer-Encoding of
545 7bit rather than sometimes being marked as 8bit.
546
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000547- Issue #8375: test_distutils now checks if the temporary directory are still
548 present before it cleans them.
549
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000550- Issue #8374: Update the internal alias table in the :mod:`locale` module
551 to cover recent locale changes and additions.
552
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000553- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
554 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
555 and `ssl.OPENSSL_VERSION_NUMBER`.
556
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000557- Add functools.total_ordering() and functools.cmp_to_key().
558
Mark Dickinson089b00c2010-04-03 15:51:03 +0000559- Issue #8257: The Decimal construct now accepts a float instance
560 directly, converting that float to a Decimal of equal value:
561
562 >>> Decimal(1.1)
563 Decimal('1.100000000000000088817841970012523233890533447265625')
564
Mark Dickinson98127c32010-04-03 11:18:52 +0000565- Issue #8294: The Fraction constructor now accepts Decimal and float
566 instances directly.
567
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000568- Issue #7279: Comparisons involving a Decimal signaling NaN now
569 signal InvalidOperation instead of returning False. (Comparisons
570 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
571 are now hashable; Decimal signaling NaNs remain unhashable.
572
573- Issue #2531: Comparison operations between floats and Decimal
574 instances now return a result based on the numeric values of the
575 operands; previously they returned an arbitrary result based on
576 the relative ordering of id(float) and id(Decimal).
577
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000578- Added a subtract() method to collections.Counter().
579
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000580- Issue #8233: When run as a script, py_compile.py optionally takes a single
581 argument `-` which tells it to read files to compile from stdin. Each line
582 is read on demand and the named file is compiled immediately. (Original
583 patch by Piotr Ożarowski).
584
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000585- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
586 form feed (0x0C) are now considered linebreaks, as specified in Unicode
587 Standard Annex #14. See issue #7643.
588 http://www.unicode.org/reports/tr14/
589
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000590- Comparisons using one of <, <=, >, >= between a complex instance and
591 a Fractions instance now raise TypeError instead of returning
592 True/False. This makes Fraction <=> complex comparisons consistent with
593 int <=> complex, float <=> complex, and complex <=> complex comparisons.
594
Antoine Pitrou39b35432010-03-23 00:25:54 +0000595- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
596 some methods (such as oss_mixer_device.fileno()) were not available.
597 Initial patch by Bertrand Janin.
598
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000599- Issue #8205: Remove the "Modules" directory from sys.path when Python is
600 running from the build directory (POSIX only).
601
Antoine Pitrou910bd512010-03-22 20:11:09 +0000602- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
603 didn't support chflags() (for example ZFS under FreeBSD). The error is
604 now silenced.
605
R. David Murrayca2edce2010-03-22 17:48:48 +0000606- Issue #7860: platform.uname now reports the correct 'machine' type
607 when Python is running in WOW64 mode on 64 bit Windows.
608
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000609- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
610 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
611 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000612
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000613- Issue #4282: Fix the main function of the profile module for a non-ASCII
614 script, open the file in binary mode and not in text mode with the default

Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000636- The internals of the subprocess module on POSIX systems have been replaced
637 by an extension module (_posixsubprocess) so that the fork()+exec() can be
638 done safely without the possibility of deadlock in multithreaded applications.
639
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000640- subprocess.Popen now has restore_signals and start_new_session features.
641 The default of restore_signals=True is a new behavior compared to earlier
642 Python versions. This means that signals such as SIGPIPE are not ignored
643 by default in subprocesses launched by Python (Issue #1652).
644
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000645- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

705 exception of canonical and is_canonical) now accept instances of int
706 and long wherever a Decimal instance is accepted, and implicitly
707 convert that argument to Decimal. Previously only some arguments
708 were converted.

731 file position when calling `truncate()`. It would previously change the
732 file position to the given argument, which goes against the tradition of
733 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

736 :class:`zipfile.ZipExtFile` class used to represent files stored inside
737 an archive. The new implementation is significantly faster and can

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

Victor Stinnere125f132010-05-15 21:04:43 +0000926 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +0000927 recursive locks as fast as regular non-recursive locks (previously,
928 they were slower by 10x to 15x).

1401 leak-chasing test runs give sensible results. The previous method of
1402 reaping threads could return successfully while some Thread objects were
1403 still referenced. This also introduces a new private function:
1404 :func:`_thread._count()`.

1408
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001409- Issue #7055: test___all__ now greedily detects all modules which have an

1414 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001415
Mark Dickinson2e304402009-10-04 18:43:54 +00001416- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1417

1586 was locale aware; and (3) the interpretation of fromhex('-nan')
1587 didn't match that of float('-nan').

1610
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001611- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1612 than an int, which makes some operations possible under 64-bit Linux (e.g.
1613 DN_MULTISHOT with F_NOTIFY).
1614

1638 library. This means, for example, that opening an UTF-16 text file in
1639 append mode doesn't add a BOM at the end of the file if the file isn't
1640 empty.

1692
Mark Dickinson865e01a2009-05-07 16:37:01 +00001693- Issue #5914: Add new C API function PyOS_string_to_double, and
1694 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1695
Eric Smith741191f2009-05-06 13:08:15 +00001696- Issue #3382: float.__format__, complex.__format__, and %-formatting
1697 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1698 affects nan -> NAN and inf -> INF.
1699
Mark Hammond5a607a32009-05-06 08:04:54 +00001700- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1701 in all operations, including splitdrive, split, etc. splitunc() now issues
1702 a PendingDeprecation warning.
1703
Eric Smith63376222009-05-05 14:04:18 +00001704- Issue #5920: For float.__format__, change the behavior with the
1705 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1706 to be like 'g' but with at least one decimal point and with a
1707 default precision of 12. Previously, the behavior the same but with
1708 a default precision of 6. This more closely matches str(), and
1709 reduces surprises when adding alignment flags to the empty
1710 presentation type. This also affects the new complex.__format__ in
1711 the same way.
1712
Martin v. Löwis011e8422009-05-05 04:43:17 +00001713- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1716 shadowed by classtype's, even if it was None. property now
1717 inserts the __doc__ into the subclass instance __dict__.
1718
Antoine Pitrou244651a2009-05-04 18:56:13 +00001719- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1720 sequences. Patch by Nick Barnes and Victor Stinner.
1721
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001722- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001723
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001724- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1725 received a new method, detach(). detach() disconnects the underlying stream
1726 from the buffer or text IO and returns it.
1727
Mark Dickinson33841c32009-05-01 15:37:04 +00001728- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1729 floats with absolute value over 1e50. Also remove length
1730 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1731 12.34 no longer raise an exception.

Eric Smith741191f2009-05-06 13:08:15 +00001733- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001734 format(complex(1, 2./3), '.5') now produces a sensible result.
1735
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001736- Issue #5864: Fix empty format code formatting for floats so that it
1737 never gives more than the requested number of significant digits.
1738
Eric Smith6dc46f52009-04-27 20:39:49 +00001739- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00001749- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1750 z involves nans, infs or negative zeros.
1751
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001752- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001753
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001754- Issue #1869 (and many duplicates): make round(x, n) correctly
1755 rounded for a float x, by using the decimal <-> binary conversions
1756 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1757 consistently agrees with format(x, '.2f').
1758
Benjamin Petersonae937c02009-04-18 20:54:08 +00001759- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

1765 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001766
1767- Implement PEP 378, Format Specifier for Thousands Separator, for
1768 floats.

Mark Dickinson3370cce2009-04-17 22:40:53 +00001770- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001771 1e11, not 1e12. This avoids printing 13 significant digits in
1772 situations where only 12 of them are correct. Example problem
1773 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1774 long time.)
1775
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001776- Issue #1580: On most platforms, use a 'short' float repr: for a
1777 finite float x, repr(x) now outputs a string based on the shortest
1778 sequence of decimal digits that rounds to x. Previous behaviour was
1779 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001780 Another minor difference is that the new repr switches to
1781 exponential notation at 1e16 instead of the previous 1e17; this
1782 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001783
1784 There's a new sys attribute sys.float_repr_style, which takes
1785 the value 'short' to indicate that we're using short float repr,
1786 and 'legacy' if the short float repr isn't available for one
1787 reason or another.
1788
1789 The float repr change involves incorporating David Gay's 'perfect
1790 rounding' code into the Python core (it's in Python/dtoa.c). As a
1791 secondary consequence, all string-to-float and float-to-string
1792 conversions (including all float formatting operations) will be
1793 correctly rounded on these platforms.
1794
1795 See issue 1580 discussions for details of platforms for which
1796 this change does not apply.

1799
Georg Brandlabc38772009-04-12 15:51:51 +00001800- The string.maketrans() function is deprecated; there is a new static method
1801 maketrans() on the bytes and bytearray classes. This removes confusion about
1802 the types string.maketrans() is supposed to work with, and mirrors the
1803 methods available on the str class.

1970 untrackable objects are not tracked by the garbage collector. This can
1971 reduce the size of collections and therefore the garbage collection overhead
1972 on long-running programs, depending on their particular use of datatypes.

2093 rotating the object pointer by 4 bits to the right.
2094
Mark Dickinson87ec0852009-02-09 17:15:59 +00002095- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002107
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002108- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002109 were suppressing all exceptions. These include list() and bytearray().

2113
Antoine Pitroub52ec782009-01-25 16:34:23 +00002114- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2115 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2116 evaluation loop is compiled with a new dispatch mechanism which gives
2117 speedups of up to 20%, depending on the system, on various benchmarks.
2118
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002119- Issue #4874: Most builtin decoders now reject unicode input.

2125
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002126- Issue #4838: When a module is deallocated, free the memory backing the
2127 optional module state data.
2128
Mark Dickinson8055afd2009-01-17 10:04:45 +00002129- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2130 type to (void *).
2131
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002132- Issue #4935: The overflow checking code in the expandtabs() method common
2133 to str, bytes and bytearray could be optimized away by the compiler, letting
2134 the interpreter segfault instead of raising an error.
2135
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002136- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2137 __next__ method.
2138
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002139- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2140 function no longer attempt to call the __long__ slot to convert an object
2141 to an integer. Only the __int__ and __trunc__ slots are examined.
2142
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002143- Issue #4893: Use NT threading on CE.

2146
Antoine Pitrouab868312009-01-10 15:40:25 +00002147- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2148 common cases are optimized thanks to a dedicated fast path and a moderate
2149 amount of loop unrolling.
2150
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002151- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2152 collecting the oldest generation) so that allocating lots of objects without
2153 destroying them does not show quadratic performance. Based on a proposal by
2154 Martin von Löwis at
2155 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2156
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002157- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002158 having been closed (for instance, a read() call could return some
2159 previously buffered data). Patch by Dmitry Vasiliev.
2160
Antoine Pitrou05608432009-01-09 18:53:14 +00002161- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2162 flag to work properly. Furthermore, when specifying -u, the text stdout
2163 and stderr streams have line-by-line buffering enabled (the default being
2164 to buffer arbitrary chunks of data).
2165
Raymond Hettinger35631532009-01-09 03:58:09 +00002166- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2167 instead of ints (reducing its size from 4 to 8 times thereby reducing
2168 Python's overall memory).
2169
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002170- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2171 an existing .py counterpart, override the co_filename attributes of all
2172 code objects if the original filename is obsolete (which can happen if the
2173 file has been renamed, moved, or if it is accessed through different paths).
2174 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2175
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002176- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2177 one byte. Also fixes the meaning of len() so that it returns the number of
2178 items, rather than the size in bytes.
2179
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002180- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2181
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002182- Issue #4747: When the terminal does not use utf-8, executing a script with
2183 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2184
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002185- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002186 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002187
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002188- Issue #3680: Reference cycles created through a dict, set or deque iterator
2189 did not get collected.
2190
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002191- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2192 where the tp_hash and tp_dict slots are both NULL.
2193
Georg Brandlccc47b62008-12-28 11:44:14 +00002194- Issue #4759: None is now allowed as the first argument of
2195 bytearray.translate(). It was always allowed for bytes.translate().
2196
Skip Montanaro80072cb2008-12-23 03:51:14 +00002197- Added test case to ensure attempts to read from a file opened for writing
2198 fail.
2199
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002200- Issue #3106: Speedup some comparisons (str/str and int/int).

2204
Antoine Pitrou621601a2008-12-17 23:18:19 +00002205- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2206 print elapsed times, not only when some objects are uncollectable /
2207 unreachable. Original patch by Neil Schemenauer.
2208
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002209- Issue #3439: Add a bit_length method to int.
2210
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002211- Issue #2173: When getting device encoding, check that return value of
2212 nl_langinfo is not the empty string. This was causing silent build
2213 failures on OS X.
2214
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002215- Issue #4597: Fixed several opcodes that weren't always propagating
2216 exceptions.
2217
2218- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002219 context manager returns a value that cannot be converted to a bool.
2220
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002221- Issue #4445: Replace "sizeof(PyBytesObject)" with
2222 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2223 bytes instances. On a typical machine this saves 3 bytes of memory
2224 (on average) per allocation of a bytes instance.
2225
Christian Heimesa872de52008-12-05 08:26:55 +00002226- Issue #4533: File read operation was dreadfully slow due to a slowly
2227 growing read buffer. Fixed by using the same growth rate algorithm as
2228 Python 2.x.
2229
Antoine Pitrou5504e892008-12-06 21:27:53 +00002230- Issue #4509: Various issues surrounding resize of bytearray objects to
2231 which there are buffer exports (e.g. memoryview instances).
2232
Georg Brandlf9734072008-12-07 15:30:06 +00002233- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2234 method on file objects with closefd=False. The file descriptor is still
2235 kept open but the file object behaves like a closed file. The ``FileIO``
2236 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002237
Antoine Pitroubc420402008-12-07 20:14:49 +00002238- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2244
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002245- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2246 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2247 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2248 of using the replace error handler in PyUnicode_DecodeUTF8().
