10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Victor Stinner33109a12010-05-28 21:55:10 +000015- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
16 used anymore and it was never documented.
17
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000018- Issue #2844: Make int('42', n) consistently raise ValueError for
19 invalid integers n (including n = -909).
20
Mark Dickinsondc787d22010-05-23 13:33:13 +000021- Issue #8188: Introduce a new scheme for computing hashes of numbers
22 (instances of int, float, complex, decimal.Decimal and
23 fractions.Fraction) that makes it easy to maintain the invariant
24 that hash(x) == hash(y) whenever x and y have equal value.
25
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000026- Issue #8748: Fix two issues with comparisons between complex and integer
27 objects. (1) The comparison could incorrectly return True in some cases
28 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
29 (2) The comparison raised an OverflowError for large integers, leading
30 to unpredictable exceptions when combining integers and complex objects
31 in sets or dicts.
32
Victor Stinner7d79b8b2010-05-19 20:40:50 +000033- Issue #8766: Initialize _warnings module before importing the first module.
34 Fix a crash if an empty directory called "encodings" exists in sys.path.
35
Victor Stinner9ca9c252010-05-19 16:53:30 +000036- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
37 encoding and surrogateespace error handler instead of the locale encoding to
38 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
39
Victor Stinner372ac5e2010-05-17 01:26:01 +000040- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
41 (instead of strict) error handler to escape surrogates
42
Victor Stinnerae6265f2010-05-15 16:27:27 +000043- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
44 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000045 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
46 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000047
Victor Stinner59e62db2010-05-15 13:14:32 +000048- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
49 error handler, not only the default error handler (strict)
50
Victor Stinnerb744ba12010-05-15 12:27:16 +000051- Issue #8610: Load file system codec at startup, and display a fatal error on
52 failure. Set the file system encoding to utf-8 (instead of None) if getting
53 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
54
Victor Stinner0964ee12010-04-30 16:48:45 +000055- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
56 PyUnicode_FromString() to support surrogates in the filename and use the
57 right encoding
58
Georg Brandl8569e582010-05-19 20:57:08 +000059- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
60
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000061- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
62
Benjamin Petersonfb886362010-04-24 18:21:17 +000063- Issue #8419: Prevent the dict constructor from accepting non-string keyword
64 arguments.
65
Victor Stinner14284c22010-04-23 12:02:30 +000066- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
67 indirectly Python signal handlers anymore because mywrite() ignores
68 exceptions (KeyboardInterrupt)
69
Victor Stinner31be90b2010-04-22 19:38:16 +000070- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
71 unicode string (eg. backslashreplace)
72
Victor Stinnerdcb24032010-04-22 12:08:36 +000073- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
74 you have to convert your bytearray filenames to bytes
75
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000076- Issue #7332: Remove the 16KB stack-based buffer in
77 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
78 benefit compared to the dynamic memory allocation fallback. Patch by
79 Charles-François Natali.
80
Benjamin Peterson8380dd52010-04-16 22:51:37 +000081- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
82 passed to bytes or bytearray.
83
Philip Jenvey0805ca32010-04-07 04:04:10 +000084- Issue #7301: Add environment variable $PYTHONWARNINGS.
85
Benjamin Petersond856ab62010-04-06 21:55:16 +000086- Issue #8329: Don't return the same lists from select.select when no fds are
87 changed.
88
Mark Dickinson3318d292010-04-06 16:53:17 +000089- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
90 on 64-bit machines. The shift count for either left or right shift is
91 permitted to be up to sys.maxsize.
92
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000093- Ensure that tokenization of identifiers is not affected by locale.

100 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000101
Victor Stinner120c2122010-03-25 00:30:28 +0000102- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
103 is unknown
104
Victor Stinner808fc0a2010-03-22 12:50:40 +0000105- Issue #1583863: An str subclass can now override the __str__ method
106
Mark Dickinsond59b4162010-03-13 11:34:40 +0000107- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
108 PyMemberDefs could produce an internal error; raise TypeError instead.
109
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000110- Issue #7845: Rich comparison methods on the complex type now return
111 NotImplemented rather than raising a TypeError when comparing with an
112 incompatible type; this allows user-defined classes to implement their own
113 comparisons with complex.
114
Victor Stinner52f6dd72010-03-12 14:45:56 +0000115- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
116 (SIGINT). If an error occurs while importing the site module, the error is
117 printed and Python exits. Initialize the GIL before importing the site
118 module.
119
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000120- Issue #7173: Generator finalization could invalidate sys.exc_info().

129
Larry Hastings1373a072010-02-24 22:49:58 +0000130- Issue #5939: Add additional runtime checking to ensure a valid capsule
131 in Modules/_ctypes/callproc.c.

144 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
145 and PyOS_string_to_double instead. See issue #5835 for the original
146 deprecations.
147
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000148- Issue #7385: Fix a crash in `MemoryView_FromObject` when
149 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
150
Mark Dickinsonbc099642010-01-29 17:27:24 +0000151- Issue #7788: Fix an interpreter crash produced by deleting a list
152 slice with very large step value.
153
Eric Smithf7bb5782010-01-27 00:44:57 +0000154- Issue #7766: Change sys.getwindowsversion() return value to a named
155 tuple and add the additional members returned in an OSVERSIONINFOEX

157 suite_mask, and product_type.
158
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000159- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
160 could crash in many places because of the PyByteArray_AS_STRING() macro
161 returning NULL. The macro now returns a statically allocated empty
162 string instead.
163
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000164- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
165 where the right hand operand is a set of constants, by turning the set into
166 a frozenset and pre-building it as a constant. The comparison operation
167 is made against the constant instead of building a new set each time it is
168 executed (a similar optimization already existed which turned a list of
169 constants into a pre-built tuple). Patch and additional tests by Dave
170 Malcolm.
171
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000172- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
173 methods of bytes, bytearray and unicode objects by using a common
174 implementation based on stringlib's fast search. Patch by Florent Xicluna.
175
Mark Dickinson45b63652010-01-16 18:10:25 +0000176- Issue #7632: Fix various str -> float conversion bugs present in 2.7
177 alpha 2, including: (1) a serious 'wrong output' bug that could
178 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
179 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000180 strings corresponding to subnormal values, (3) a memory leak for
181 some values large enough to cause overflow, and (4) a number of
182 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000183
Benjamin Petersonaea44282010-01-04 01:10:28 +0000184- The __complex__ method is now looked up on the class of instances to make it
185 consistent with other special methods.

188 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
189
Benjamin Petersond12362a2009-12-30 19:44:54 +0000190- Issue #7604: Deleting an unset slotted attribute did not raise an
191 AttributeError.

Mark Dickinson9ab44b52009-12-30 16:22:49 +0000193- Issue #7534: Fix handling of IEEE specials (infinities, nans,
194 negative zero) in ** operator. The behaviour now conforms to that
195 described in C99 Annex F.
196
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000197- Issue #1811: improve accuracy and cross-platform consistency for
198 true division of integers: the result of a/b is now correctly
199 rounded for ints a and b (at least on IEEE 754 platforms), and in
200 particular does not depend on the internal representation of an int.
201
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000202- Issue #6834: replace the implementation for the 'python' and 'pythonw'
203 executables on OSX.
204
205 These executables now work properly with the arch(1) command:
206 ``arch -ppc python`` will start a universal binary version of python
207 in PPC mode (unlike previous releases).
208
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000209- Issue #7466: segmentation fault when the garbage collector is called

217
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000218- Issue #7085: Fix crash when importing some extensions in a thread
219 on MacOSX 10.6.
220
Philip Jenvey1309adb2009-11-17 03:43:14 +0000221- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

224 implement the relevant rich comparison methods.
225
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000226- Issue #7298: fixes for range and reversed(range(...)). Iteration
227 over range(a, b, c) incorrectly gave an empty iterator when a, b and
228 c fit in C long but the length of the range did not. Also fix
229 several cases where reversed(range(a, b, c)) gave wrong results, and
230 fix a refleak for reversed(range(a, b, c)) with large arguments.
231
Raymond Hettingerfc438512009-11-01 20:55:33 +0000232- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitrouf978fac2010-05-21 17:25:34 +0000342- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
343 embedders of the interpreter to set sys.argv without also modifying
344 sys.path. This helps fix `CVE-2008-5983
345 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
346
Benjamin Petersonfb886362010-04-24 18:21:17 +0000347- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are

362 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
363 DeprecationWarning for float arguments passed with the 'L' format
364 code. This will become a TypeError in a future version of Python,
365 to match the behaviour of the other integer format codes.

Victor Stinner0e59cc32010-04-16 23:49:32 +0000613- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
614 the current working directory.
615
Victor Stinner5bfe1462010-04-16 13:28:05 +0000616- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
617 using backslashreplace error handler
618

620 surrogates.
621
Senthil Kumaranad02d232010-04-16 03:02:13 +0000622- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
623 Locke and Hans Ulrich Niedermann.

626
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000627- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
628 module now takes an optional timeout argument in seconds. Timeout support
629 relies on the system threading library, so as to avoid a semi-busy wait
630 loop.
631
Victor Stinner485fb562010-04-13 11:07:24 +0000632- Issue #8383: pickle and pickletools use surrogatepass error handler when
633 encoding unicode as utf8 to support lone surrogates and stay compatible with
634 Python 2.x and 3.0
635
R. David Murrayb2416e52010-04-12 16:58:02 +0000636- Issue #7585: difflib context and unified diffs now place a tab between
637 filename and date, conforming to the 'standards' they were originally
638 designed to follow. This improves compatibility with patch tools.
639
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000640- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
641 character sets will now consistently use a Content-Transfer-Encoding of
642 7bit rather than sometimes being marked as 8bit.
643
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000644- Issue #8375: test_distutils now checks if the temporary directory are still
645 present before it cleans them.
646
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000647- Issue #8374: Update the internal alias table in the :mod:`locale` module
648 to cover recent locale changes and additions.
649
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000650- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
651 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
652 and `ssl.OPENSSL_VERSION_NUMBER`.
653
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000654- Add functools.total_ordering() and functools.cmp_to_key().
655
Mark Dickinson089b00c2010-04-03 15:51:03 +0000656- Issue #8257: The Decimal construct now accepts a float instance
657 directly, converting that float to a Decimal of equal value:
658
659 >>> Decimal(1.1)
660 Decimal('1.100000000000000088817841970012523233890533447265625')
661
Mark Dickinson98127c32010-04-03 11:18:52 +0000662- Issue #8294: The Fraction constructor now accepts Decimal and float
663 instances directly.
664
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000665- Issue #7279: Comparisons involving a Decimal signaling NaN now
666 signal InvalidOperation instead of returning False. (Comparisons
667 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
668 are now hashable; Decimal signaling NaNs remain unhashable.
669
670- Issue #2531: Comparison operations between floats and Decimal
671 instances now return a result based on the numeric values of the
672 operands; previously they returned an arbitrary result based on
673 the relative ordering of id(float) and id(Decimal).
674
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000675- Added a subtract() method to collections.Counter().
676
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000677- Issue #8233: When run as a script, py_compile.py optionally takes a single
678 argument `-` which tells it to read files to compile from stdin. Each line
679 is read on demand and the named file is compiled immediately. (Original
680 patch by Piotr Ożarowski).
681
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000682- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
683 form feed (0x0C) are now considered linebreaks, as specified in Unicode
684 Standard Annex #14. See issue #7643.
685 http://www.unicode.org/reports/tr14/
686
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000687- Comparisons using one of <, <=, >, >= between a complex instance and
688 a Fractions instance now raise TypeError instead of returning
689 True/False. This makes Fraction <=> complex comparisons consistent with
690 int <=> complex, float <=> complex, and complex <=> complex comparisons.
691
Antoine Pitrou39b35432010-03-23 00:25:54 +0000692- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
693 some methods (such as oss_mixer_device.fileno()) were not available.
694 Initial patch by Bertrand Janin.
695
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000696- Issue #8205: Remove the "Modules" directory from sys.path when Python is
697 running from the build directory (POSIX only).
698
Antoine Pitrou910bd512010-03-22 20:11:09 +0000699- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
700 didn't support chflags() (for example ZFS under FreeBSD). The error is
701 now silenced.
702
R. David Murrayca2edce2010-03-22 17:48:48 +0000703- Issue #7860: platform.uname now reports the correct 'machine' type
704 when Python is running in WOW64 mode on 64 bit Windows.
705
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000706- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
707 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
708 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000709
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000710- Issue #4282: Fix the main function of the profile module for a non-ASCII
711 script, open the file in binary mode and not in text mode with the default
712 (utf8) encoding.
713
Florent Xicluna54467e02010-03-21 12:29:50 +0000714- Issue #8179: Fix macpath.realpath() on a non-existing path.

719
Benjamin Peterson689a5582010-03-18 22:29:52 +0000720- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
721 detected.
722
Martin v. Löwis4b003072010-03-16 13:19:21 +0000723- Issue #6716/2: Backslash-replace error output in compilall.
724
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000725- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
726 with Tcl/Tk-8.5.
727
Matthias Klosec33b9022010-03-16 00:36:26 +0000728- Issue #8140: extend compileall to compile single files. Add -i option.

731 the locale.
732
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000733- The internals of the subprocess module on POSIX systems have been replaced
734 by an extension module (_posixsubprocess) so that the fork()+exec() can be
735 done safely without the possibility of deadlock in multithreaded applications.
736
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000737- subprocess.Popen now has restore_signals and start_new_session features.
738 The default of restore_signals=True is a new behavior compared to earlier
739 Python versions. This means that signals such as SIGPIPE are not ignored
740 by default in subprocesses launched by Python (Issue #1652).
741
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000742- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
743 cElementTree module is updated too.

752 the replacement were all bytes. Patch by Antoine Pitrou.
753
Gerhard Häringf9cee222010-03-05 15:20:03 +0000754- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
755 bugs and allows loading SQLite extensions from shared libraries.

788 to be ignored only to the first file. Noted by Bogdan Opanchuk.
789
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000790- Issue #7597: curses.use_env() can now be called before initscr().
791 Noted by Kan-Ru Chen.
792

799 bytecode file when it was less then 8 bytes.
800
Mark Dickinson84230a12010-02-18 14:49:50 +0000801- Issue #7633: In the decimal module, Context class methods (with the
802 exception of canonical and is_canonical) now accept instances of int
803 and long wherever a Decimal instance is accepted, and implicitly
804 convert that argument to Decimal. Previously only some arguments
805 were converted.
806
R. David Murray1f449142010-02-11 00:15:05 +0000807- Issue #7835: shelve should no longer produce mysterious warnings during
808 interpreter shutdown.
809
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000810- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
811 in XML processing instructions and comments. These raw characters are
812 allowed by the XML specification, and are necessary when outputting e.g.
813 PHP code in a processing instruction. Patch by Neil Muller.

825 type is specified. Patch by Brian Curtin.
826
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000827- Issue #6939: Fix file I/O objects in the `io` module to keep the original
828 file position when calling `truncate()`. It would previously change the
829 file position to the given argument, which goes against the tradition of
830 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
831
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000832- Issue #7610: Reworked implementation of the internal
833 :class:`zipfile.ZipExtFile` class used to represent files stored inside
834 an archive. The new implementation is significantly faster and can
835 be wrapped in a :class:`io.BufferedReader` object for more speedups.
836 It also solves an issue where interleaved calls to `read()` and
837 `readline()` give wrong results. Patch by Nir Aides.
838
Jesse Noller1f0b6582010-01-27 03:36:01 +0000839- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

841 the worker before that worker is terminated, and a new one created to
842 replace it.
843
Benjamin Petersond6326642010-01-27 02:25:58 +0000844- Issue #7792: Registering non-classes to ABCs raised an obscure error.

999
Nick Coghlan260bd3e2009-11-16 06:49:25 +00001000- Issue #6816: runpy now provides a run_path function that allows Python code
1001 to execute file paths that refer to source or compiled Python files as well
1002 as zipfiles, directories and other valid sys.path entries that contain a
1003 __main__.py file. This allows applications that run other Python scripts to
1004 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001023 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001024 recursive locks as fast as regular non-recursive locks (previously,
1025 they were slower by 10x to 15x).

1045 reading from stdin so that existing input does not confuse it and
1046 lead to incorrect entry or an IOError. It also properly flushes it
1047 afterwards to avoid the terminal echoing the input afterwards on
1048 OSes such as Solaris.

R. David Murraye9e95932010-02-06 05:00:15 +00001467
R. David Murray445448c2009-12-20 17:28:31 +00001468- Issue #7376: instead of running a self-test (which was failing) when called

Victor Stinnere125f132010-05-15 21:04:43 +00001476- Issue #7431: use TESTFN in test_linecache instead of trying to create a
R. David Murrayba311052009-12-04 00:09:14 +00001477 file in the Lib/test directory, which might be read-only for the
1478 user running the tests.
1479
R. David Murray35768ad2009-11-15 00:23:21 +00001480- Issue #7324: add a sanity check to regrtest argument parsing to

Antoine Pitrou060cee22009-11-13 16:29:04 +00001486- Issue #6551: test_zipimport could import and then destroy some modules of

1502 calling methods on the object.
1503
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001504- Issue #7222: Make thread "reaping" more reliable so that reference
1505 leak-chasing test runs give sensible results. The previous method of
1506 reaping threads could return successfully while some Thread objects were
1507 still referenced. This also introduces a new private function:
1508 :func:`_thread._count()`.
1509
R. David Murray27144602009-10-19 15:26:16 +00001510- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1511 longer runs the risk of causing the worker thread to fail.
1512
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001513- Issue #7055: test___all__ now greedily detects all modules which have an
1514 __all__ attribute, rather than using a hardcoded and incomplete list.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001789What's New in Python 3.1 beta 1?
1790================================
1791
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001792*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001793
1794Core and Builtins
1795-----------------
1796
Mark Dickinson865e01a2009-05-07 16:37:01 +00001797- Issue #5914: Add new C API function PyOS_string_to_double, and
1798 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1799
Eric Smith741191f2009-05-06 13:08:15 +00001800- Issue #3382: float.__format__, complex.__format__, and %-formatting
1801 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1802 affects nan -> NAN and inf -> INF.
1803
Mark Hammond5a607a32009-05-06 08:04:54 +00001804- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1805 in all operations, including splitdrive, split, etc. splitunc() now issues
1806 a PendingDeprecation warning.
1807
Eric Smith63376222009-05-05 14:04:18 +00001808- Issue #5920: For float.__format__, change the behavior with the
1809 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1810 to be like 'g' but with at least one decimal point and with a
1811 default precision of 12. Previously, the behavior the same but with
1812 a default precision of 6. This more closely matches str(), and
1813 reduces surprises when adding alignment flags to the empty
1814 presentation type. This also affects the new complex.__format__ in
1815 the same way.
1816
Martin v. Löwis011e8422009-05-05 04:43:17 +00001817- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1818
R. David Murrayb18500d2009-05-04 22:59:07 +00001819- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1820 shadowed by classtype's, even if it was None. property now
1821 inserts the __doc__ into the subclass instance __dict__.
1822
Antoine Pitrou244651a2009-05-04 18:56:13 +00001823- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1824 sequences. Patch by Nick Barnes and Victor Stinner.
1825
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001826- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001827
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001828- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1829 received a new method, detach(). detach() disconnects the underlying stream
1830 from the buffer or text IO and returns it.
1831
Mark Dickinson33841c32009-05-01 15:37:04 +00001832- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1833 floats with absolute value over 1e50. Also remove length
1834 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1835 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001836
Eric Smith741191f2009-05-06 13:08:15 +00001837- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001838 format(complex(1, 2./3), '.5') now produces a sensible result.
1839
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001840- Issue #5864: Fix empty format code formatting for floats so that it
1841 never gives more than the requested number of significant digits.
1842
Eric Smith6dc46f52009-04-27 20:39:49 +00001843- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1844 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1845
Eric Smithcc32a112009-04-26 21:35:14 +00001846- Issue #5835: Deprecate PyOS_ascii_formatd.
1847
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001848- Issue #4971: Fix titlecase for characters that are their own
1849 titlecase, but not their own uppercase.
1850
Benjamin Peterson193152c2009-04-25 01:08:45 +00001851- Issue #5283: Setting __class__ in __del__ caused a segfault.
1852
Mark Dickinsonad476da2009-04-23 19:14:16 +00001853- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1854 z involves nans, infs or negative zeros.
1855
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001856- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001857
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001858- Issue #1869 (and many duplicates): make round(x, n) correctly
1859 rounded for a float x, by using the decimal <-> binary conversions
1860 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1861 consistently agrees with format(x, '.2f').
1862
Benjamin Petersonae937c02009-04-18 20:54:08 +00001863- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1864 some builtin types.
1865
Eric Smith0923d1d2009-04-16 20:16:10 +00001866- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1867
Eric Smith35e84722009-04-16 20:21:28 +00001868- Issue #5515: str.format() type 'n' combined with commas and leading
1869 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001870
1871- Implement PEP 378, Format Specifier for Thousands Separator, for
1872 floats.
1873
Mark Dickinson3370cce2009-04-17 22:40:53 +00001874- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001875 1e11, not 1e12. This avoids printing 13 significant digits in
1876 situations where only 12 of them are correct. Example problem
1877 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1878 long time.)
1879
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001880- Issue #1580: On most platforms, use a 'short' float repr: for a
1881 finite float x, repr(x) now outputs a string based on the shortest
1882 sequence of decimal digits that rounds to x. Previous behaviour was
1883 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001884 Another minor difference is that the new repr switches to
1885 exponential notation at 1e16 instead of the previous 1e17; this
1886 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001887
1888 There's a new sys attribute sys.float_repr_style, which takes
1889 the value 'short' to indicate that we're using short float repr,
1890 and 'legacy' if the short float repr isn't available for one
1891 reason or another.
1892
1893 The float repr change involves incorporating David Gay's 'perfect
1894 rounding' code into the Python core (it's in Python/dtoa.c). As a
1895 secondary consequence, all string-to-float and float-to-string
1896 conversions (including all float formatting operations) will be
1897 correctly rounded on these platforms.
1898
1899 See issue 1580 discussions for details of platforms for which
1900 this change does not apply.
1901
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001902- Issue #5759: float() didn't call __float__ on str subclasses.
1903
Georg Brandlabc38772009-04-12 15:51:51 +00001904- The string.maketrans() function is deprecated; there is a new static method
1905 maketrans() on the bytes and bytearray classes. This removes confusion about
1906 the types string.maketrans() is supposed to work with, and mirrors the
1907 methods available on the str class.
1908
R. David Murraydc6da8a2009-04-09 22:16:43 +00001909- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1910 its clarity and its speed.
1911
Matthias Klose091c7b12009-04-07 13:24:27 +00001912- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1913 to avoid compiler warnings.
1914
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001915- Issue #3739: The unicode-internal encoder now reports the number of characters

Guido van Rossum0ad59d42009-03-30 22:01:35 +00002064- Issue #5604: non-ASCII characters in module name passed to
2065 imp.find_module() were converted to UTF-8 while the path is
2066 converted to the default filesystem encoding, causing nonsense.
2067
Benjamin Peterson09832742009-03-26 17:15:46 +00002068- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002070- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2071 the end sys.path, for compatibility with the system install of Python.
2072
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002073- Issue #4688: Add a heuristic so that tuples and dicts containing only
2074 untrackable objects are not tracked by the garbage collector. This can
2075 reduce the size of collections and therefore the garbage collection overhead
2076 on long-running programs, depending on their particular use of datatypes.
2077
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002078- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2079 improve its performance. Long divisions and remainder operations
2080 are now between 50% and 150% faster.
2081
Mark Dickinsonbd792642009-03-18 20:06:12 +00002082- Issue #4258: Make it possible to use base 2**30 instead of base
2083 2**15 for the internal representation of integers, for performance
2084 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2085 --enable-big-digits option to configure, which overrides the
2086 default. Add sys.int_info structseq to provide information about
2087 the internal format.
2088
Mark Dickinson081dfee2009-03-18 14:47:41 +00002089- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2090 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2091 and sizeof(Py_UNICODE) == 2.
2092
Eric Smith8ec90442009-03-14 12:29:34 +00002093- Issue #5237: Allow auto-numbered fields in str.format(). For
2094 example: '{} {}'.format(1, 2) == '1 2'.
2095
Antoine Pitrou652e7072009-03-13 19:25:20 +00002096- Issue #5392: when a very low recursion limit was set, the interpreter would
2097 abort with a fatal error after the recursion limit was hit twice.
2098
Matthias Klose042f1332009-04-04 14:32:42 +00002099- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with
2100 short file names.

2145
Lars Gustäbel42e00912009-03-22 20:34:29 +00002146- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2147 forever on incomplete input. That caused tarfile.open() to hang when used
2148 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2149 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002170 struct.error instead of returning b'\xff\xff\xff\xff'. The
2171 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

2197 rotating the object pointer by 4 bits to the right.
2198
Mark Dickinson87ec0852009-02-09 17:15:59 +00002199- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2200 it now forces its argument to double before testing for infinity.
2201
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002202- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2203 returns a non-number type.
2204
Benjamin Peterson87618552009-02-08 15:00:52 +00002205- Issue #5182: Removed memoryview.__str__.

2208 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00002209 the type definition cmpfunc. The tp_compare slot has been renamed
2210 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002211
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002212- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002213 were suppressing all exceptions. These include list() and bytearray().
2214
Mark Dickinson1124e712009-01-28 21:25:58 +00002215- Issue #4707: round(x, n) now returns an integer if x is an integer.
2216 Previously it returned a float.
2217
Antoine Pitroub52ec782009-01-25 16:34:23 +00002218- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2219 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2220 evaluation loop is compiled with a new dispatch mechanism which gives
2221 speedups of up to 20%, depending on the system, on various benchmarks.
2222
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002223- Issue #4874: Most builtin decoders now reject unicode input.

2229
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002230- Issue #4838: When a module is deallocated, free the memory backing the
2231 optional module state data.
2232
Mark Dickinson8055afd2009-01-17 10:04:45 +00002233- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2234 type to (void *).
2235
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002236- Issue #4935: The overflow checking code in the expandtabs() method common
2237 to str, bytes and bytearray could be optimized away by the compiler, letting
2238 the interpreter segfault instead of raising an error.
2239
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002240- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2241 __next__ method.
2242
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002243- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2250
Antoine Pitrouab868312009-01-10 15:40:25 +00002251- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2252 common cases are optimized thanks to a dedicated fast path and a moderate
2253 amount of loop unrolling.
2254
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002255- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2256 collecting the oldest generation) so that allocating lots of objects without
2257 destroying them does not show quadratic performance. Based on a proposal by
2258 Martin von Löwis at
2259 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2260
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002261- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002262 having been closed (for instance, a read() call could return some
2263 previously buffered data). Patch by Dmitry Vasiliev.
2264
Antoine Pitrou05608432009-01-09 18:53:14 +00002265- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2266 flag to work properly. Furthermore, when specifying -u, the text stdout
2267 and stderr streams have line-by-line buffering enabled (the default being
2268 to buffer arbitrary chunks of data).
2269
Raymond Hettinger35631532009-01-09 03:58:09 +00002270- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2271 instead of ints (reducing its size from 4 to 8 times thereby reducing
2272 Python's overall memory).
2273
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002274- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2275 an existing .py counterpart, override the co_filename attributes of all
2276 code objects if the original filename is obsolete (which can happen if the
2277 file has been renamed, moved, or if it is accessed through different paths).
2278 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2279
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002280- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2281 one byte. Also fixes the meaning of len() so that it returns the number of
2282 items, rather than the size in bytes.
2283
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002284- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2285
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002286- Issue #4747: When the terminal does not use utf-8, executing a script with
2287 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2288
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002289- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002290 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002291
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002292- Issue #3680: Reference cycles created through a dict, set or deque iterator
2293 did not get collected.
2294
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002295- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2296 where the tp_hash and tp_dict slots are both NULL.
2297
Georg Brandlccc47b62008-12-28 11:44:14 +00002298- Issue #4759: None is now allowed as the first argument of
2299 bytearray.translate(). It was always allowed for bytes.translate().
2300
Skip Montanaro80072cb2008-12-23 03:51:14 +00002301- Added test case to ensure attempts to read from a file opened for writing
2302 fail.
2303
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002304- Issue #3106: Speedup some comparisons (str/str and int/int).

2307 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2308
Antoine Pitrou621601a2008-12-17 23:18:19 +00002309- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2310 print elapsed times, not only when some objects are uncollectable /
2311 unreachable. Original patch by Neil Schemenauer.
2312
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002313- Issue #3439: Add a bit_length method to int.
2314
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002315- Issue #2173: When getting device encoding, check that return value of
2316 nl_langinfo is not the empty string. This was causing silent build
2317 failures on OS X.
2318
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002319- Issue #4597: Fixed several opcodes that weren't always propagating
2320 exceptions.
2321
2322- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002323 context manager returns a value that cannot be converted to a bool.
2324
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002325- Issue #4445: Replace "sizeof(PyBytesObject)" with
2326 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2327 bytes instances. On a typical machine this saves 3 bytes of memory
2328 (on average) per allocation of a bytes instance.
2329
Christian Heimesa872de52008-12-05 08:26:55 +00002330- Issue #4533: File read operation was dreadfully slow due to a slowly
2331 growing read buffer. Fixed by using the same growth rate algorithm as
2332 Python 2.x.
2333
Antoine Pitrou5504e892008-12-06 21:27:53 +00002334- Issue #4509: Various issues surrounding resize of bytearray objects to
2335 which there are buffer exports (e.g. memoryview instances).
2336
Georg Brandlf9734072008-12-07 15:30:06 +00002337- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2338 method on file objects with closefd=False. The file descriptor is still
2339 kept open but the file object behaves like a closed file. The ``FileIO``
2340 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002341
Antoine Pitroubc420402008-12-07 20:14:49 +00002342- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2629 inside its source path if it began with the same letters (e.g. "src" vs.
2630 "src.new").
2631

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002638- Issue #5021: doctest.testfile() did not create __name__ and

2640
2641- Backport importlib from Python 3.1. Only the import_module() function has

Jesse Noller6fd47e22009-01-23 14:09:08 +00002669 --without-threads argument. When this occurs, _multiprocessing will
2670 be disabled, and not compiled.
2671
Antoine Pitrou08838b62009-01-21 00:55:13 +00002672- Issue #5008: When a file is opened in append mode with the new IO library,
2673 do an explicit seek to the end of file (so that e.g. tell() returns the
2674 file size rather than 0). This is consistent with the behaviour of the
2675 traditional 2.x file object.

2692 without defaults.
2693
Jesse Noller6214edd2009-01-19 16:23:53 +00002694- Issue #3321: _multiprocessing.Connection() doesn't check handle; added checks
2695 for *nix machines for negative handles and large int handles. Without this check

2705 appropriately when it is being used via socket.makefile() objects
2706 rather than delaying the close by waiting for garbage collection to do it.
2707
Raymond Hettingerb8baf632009-01-14 02:20:07 +00002708- Issue #1696199: Add collections.Counter() for rapid and convenient
2709 counting.

2921 implementations or external openssl library).
2922
Mark Dickinson29500f62009-01-15 15:36:10 +00002923- Issue #4397: Fix occasional test_socket failure on OS X.

Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00002927- Issue #4751: hashlib now releases the GIL when hashing large buffers
2928 (with a hardwired threshold of 2048 bytes), allowing better parallelization
2929 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.

Antoine Pitrou31f30b12009-01-02 17:34:35 +00002933- Issue #4738: Each zlib object now has a separate lock, allowing to compress
2934 or decompress several streams at once on multi-CPU systems. Also, the GIL
2935 is now released when computing the CRC of a large buffer. Patch by ebfe.
2936
Georg Brandlb1441c72009-01-03 22:33:39 +00002937- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.

Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00002944- Issue #4583: array.array would not always prohibit resizing when a buffer
2945 has been exported, resulting in an interpreter crash when accessing the
2946 buffer.

Antoine Pitrou88909542009-06-29 13:54:42 +00002954- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2955 regression tests in parallel, shortening the total runtime.
2956
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002957- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2958 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2959 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2960 skip the tests if DISPLAY is defined but can't be used.
2961
R. David Murraya21e4ca2009-03-31 23:16:50 +00002962- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002963 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002964 from test support, which does the conversion.
2965
Guilherme Polo9de29af2009-01-28 20:40:48 +00002966- Issue #5083: New 'gui' resource for regrtest.
