10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000015- Issue #2844: Make int('42', n) consistently raise ValueError for
16 invalid integers n (including n = -909).
17
Mark Dickinsondc787d22010-05-23 13:33:13 +000018- Issue #8188: Introduce a new scheme for computing hashes of numbers
19 (instances of int, float, complex, decimal.Decimal and
20 fractions.Fraction) that makes it easy to maintain the invariant
21 that hash(x) == hash(y) whenever x and y have equal value.
22
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000023- Issue #8748: Fix two issues with comparisons between complex and integer
24 objects. (1) The comparison could incorrectly return True in some cases
25 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
26 (2) The comparison raised an OverflowError for large integers, leading
27 to unpredictable exceptions when combining integers and complex objects
28 in sets or dicts.
29
Victor Stinner7d79b8b2010-05-19 20:40:50 +000030- Issue #8766: Initialize _warnings module before importing the first module.
31 Fix a crash if an empty directory called "encodings" exists in sys.path.
32
Victor Stinner9ca9c252010-05-19 16:53:30 +000033- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
34 encoding and surrogateespace error handler instead of the locale encoding to
35 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
36
Victor Stinner372ac5e2010-05-17 01:26:01 +000037- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
38 (instead of strict) error handler to escape surrogates
39
Victor Stinnerae6265f2010-05-15 16:27:27 +000040- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
41 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000042 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
43 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000044
Victor Stinner59e62db2010-05-15 13:14:32 +000045- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
46 error handler, not only the default error handler (strict)
47
Victor Stinnerb744ba12010-05-15 12:27:16 +000048- Issue #8610: Load file system codec at startup, and display a fatal error on
49 failure. Set the file system encoding to utf-8 (instead of None) if getting
50 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
51
Victor Stinner0964ee12010-04-30 16:48:45 +000052- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
53 PyUnicode_FromString() to support surrogates in the filename and use the
54 right encoding
55
Georg Brandl8569e582010-05-19 20:57:08 +000056- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
57
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000058- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
59
Benjamin Petersonfb886362010-04-24 18:21:17 +000060- Issue #8419: Prevent the dict constructor from accepting non-string keyword
61 arguments.
62
Victor Stinner14284c22010-04-23 12:02:30 +000063- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
64 indirectly Python signal handlers anymore because mywrite() ignores
65 exceptions (KeyboardInterrupt)
66
Victor Stinner31be90b2010-04-22 19:38:16 +000067- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
68 unicode string (eg. backslashreplace)
69
Victor Stinnerdcb24032010-04-22 12:08:36 +000070- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
71 you have to convert your bytearray filenames to bytes
72
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000073- Issue #7332: Remove the 16KB stack-based buffer in
74 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
75 benefit compared to the dynamic memory allocation fallback. Patch by
76 Charles-François Natali.
77
Benjamin Peterson8380dd52010-04-16 22:51:37 +000078- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
79 passed to bytes or bytearray.
80
Philip Jenvey0805ca32010-04-07 04:04:10 +000081- Issue #7301: Add environment variable $PYTHONWARNINGS.
82
Benjamin Petersond856ab62010-04-06 21:55:16 +000083- Issue #8329: Don't return the same lists from select.select when no fds are
84 changed.
85
Mark Dickinson3318d292010-04-06 16:53:17 +000086- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
87 on 64-bit machines. The shift count for either left or right shift is
88 permitted to be up to sys.maxsize.
89
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000090- Ensure that tokenization of identifiers is not affected by locale.

97 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +000098
Victor Stinner120c2122010-03-25 00:30:28 +000099- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
100 is unknown
101
Victor Stinner808fc0a2010-03-22 12:50:40 +0000102- Issue #1583863: An str subclass can now override the __str__ method
103
Mark Dickinsond59b4162010-03-13 11:34:40 +0000104- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
105 PyMemberDefs could produce an internal error; raise TypeError instead.
106
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000107- Issue #7845: Rich comparison methods on the complex type now return
108 NotImplemented rather than raising a TypeError when comparing with an
109 incompatible type; this allows user-defined classes to implement their own
110 comparisons with complex.
111
Victor Stinner52f6dd72010-03-12 14:45:56 +0000112- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
113 (SIGINT). If an error occurs while importing the site module, the error is
114 printed and Python exits. Initialize the GIL before importing the site
115 module.
116
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000117- Issue #7173: Generator finalization could invalidate sys.exc_info().

126
Larry Hastings1373a072010-02-24 22:49:58 +0000127- Issue #5939: Add additional runtime checking to ensure a valid capsule
128 in Modules/_ctypes/callproc.c.
129
Eric Smith0facd772010-02-24 15:42:29 +0000130- Issue #7309: Fix unchecked attribute access when converting
131 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
132 strings.
133

141 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
142 and PyOS_string_to_double instead. See issue #5835 for the original
143 deprecations.
144
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000145- Issue #7385: Fix a crash in `MemoryView_FromObject` when
146 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
147
Mark Dickinsonbc099642010-01-29 17:27:24 +0000148- Issue #7788: Fix an interpreter crash produced by deleting a list
149 slice with very large step value.
150
Eric Smithf7bb5782010-01-27 00:44:57 +0000151- Issue #7766: Change sys.getwindowsversion() return value to a named
152 tuple and add the additional members returned in an OSVERSIONINFOEX
153 structure. The new members are service_pack_major, service_pack_minor,
154 suite_mask, and product_type.
155
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000156- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
157 could crash in many places because of the PyByteArray_AS_STRING() macro
158 returning NULL. The macro now returns a statically allocated empty
159 string instead.
160
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000161- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
162 where the right hand operand is a set of constants, by turning the set into
163 a frozenset and pre-building it as a constant. The comparison operation
164 is made against the constant instead of building a new set each time it is
165 executed (a similar optimization already existed which turned a list of
166 constants into a pre-built tuple). Patch and additional tests by Dave
167 Malcolm.
168
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000169- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
170 methods of bytes, bytearray and unicode objects by using a common
171 implementation based on stringlib's fast search. Patch by Florent Xicluna.
172
Mark Dickinson45b63652010-01-16 18:10:25 +0000173- Issue #7632: Fix various str -> float conversion bugs present in 2.7
174 alpha 2, including: (1) a serious 'wrong output' bug that could
175 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
176 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000177 strings corresponding to subnormal values, (3) a memory leak for
178 some values large enough to cause overflow, and (4) a number of
179 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000180
Benjamin Petersonaea44282010-01-04 01:10:28 +0000181- The __complex__ method is now looked up on the class of instances to make it
182 consistent with other special methods.
183

185 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
186
Benjamin Petersond12362a2009-12-30 19:44:54 +0000187- Issue #7604: Deleting an unset slotted attribute did not raise an
188 AttributeError.

Mark Dickinson9ab44b52009-12-30 16:22:49 +0000190- Issue #7534: Fix handling of IEEE specials (infinities, nans,
191 negative zero) in ** operator. The behaviour now conforms to that
192 described in C99 Annex F.
193
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000194- Issue #1811: improve accuracy and cross-platform consistency for
195 true division of integers: the result of a/b is now correctly
196 rounded for ints a and b (at least on IEEE 754 platforms), and in
197 particular does not depend on the internal representation of an int.
198
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000199- Issue #6834: replace the implementation for the 'python' and 'pythonw'
200 executables on OSX.
201
202 These executables now work properly with the arch(1) command:
203 ``arch -ppc python`` will start a universal binary version of python
204 in PPC mode (unlike previous releases).
205
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000206- Issue #7466: segmentation fault when the garbage collector is called

Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000215- Issue #7085: Fix crash when importing some extensions in a thread
216 on MacOSX 10.6.
217
Philip Jenvey1309adb2009-11-17 03:43:14 +0000218- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

222
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000223- Issue #7298: fixes for range and reversed(range(...)). Iteration
224 over range(a, b, c) incorrectly gave an empty iterator when a, b and
225 c fit in C long but the length of the range did not. Also fix
226 several cases where reversed(range(a, b, c)) gave wrong results, and
227 fix a refleak for reversed(range(a, b, c)) with large arguments.
228

505 Decimal operation raises multiple signals and more than one of those
506 signals is trapped, the specification determines the order in which
507 the signals should be handled. In many cases this order wasn't
508 being followed, leading to the wrong Python exception being raised.

Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000607- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
608 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
609
Victor Stinner0e59cc32010-04-16 23:49:32 +0000610- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
611 the current working directory.
612
Victor Stinner5bfe1462010-04-16 13:28:05 +0000613- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
614 using backslashreplace error handler
615

617 surrogates.
618
Senthil Kumaranad02d232010-04-16 03:02:13 +0000619- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony

623
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000624- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
625 module now takes an optional timeout argument in seconds. Timeout support
626 relies on the system threading library, so as to avoid a semi-busy wait
627 loop.
628
Victor Stinner485fb562010-04-13 11:07:24 +0000629- Issue #8383: pickle and pickletools use surrogatepass error handler when
630 encoding unicode as utf8 to support lone surrogates and stay compatible with
631 Python 2.x and 3.0
632
R. David Murrayb2416e52010-04-12 16:58:02 +0000633- Issue #7585: difflib context and unified diffs now place a tab between
634 filename and date, conforming to the 'standards' they were originally
635 designed to follow. This improves compatibility with patch tools.
636
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000637- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
638 character sets will now consistently use a Content-Transfer-Encoding of
639 7bit rather than sometimes being marked as 8bit.
640
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000641- Issue #8375: test_distutils now checks if the temporary directory are still
642 present before it cleans them.
643
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000644- Issue #8374: Update the internal alias table in the :mod:`locale` module
645 to cover recent locale changes and additions.
646
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000647- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
648 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
649 and `ssl.OPENSSL_VERSION_NUMBER`.
650
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000651- Add functools.total_ordering() and functools.cmp_to_key().
652
Mark Dickinson089b00c2010-04-03 15:51:03 +0000653- Issue #8257: The Decimal construct now accepts a float instance
654 directly, converting that float to a Decimal of equal value:
655
656 >>> Decimal(1.1)
657 Decimal('1.100000000000000088817841970012523233890533447265625')
658
Mark Dickinson98127c32010-04-03 11:18:52 +0000659- Issue #8294: The Fraction constructor now accepts Decimal and float
660 instances directly.
661
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000662- Issue #7279: Comparisons involving a Decimal signaling NaN now
663 signal InvalidOperation instead of returning False. (Comparisons
664 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
665 are now hashable; Decimal signaling NaNs remain unhashable.
666
667- Issue #2531: Comparison operations between floats and Decimal
668 instances now return a result based on the numeric values of the
669 operands; previously they returned an arbitrary result based on
670 the relative ordering of id(float) and id(Decimal).
671
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000672- Added a subtract() method to collections.Counter().
673
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000674- Issue #8233: When run as a script, py_compile.py optionally takes a single
675 argument `-` which tells it to read files to compile from stdin. Each line
676 is read on demand and the named file is compiled immediately. (Original
677 patch by Piotr Ożarowski).
678
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000679- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
680 form feed (0x0C) are now considered linebreaks, as specified in Unicode
681 Standard Annex #14. See issue #7643.
682 http://www.unicode.org/reports/tr14/
683
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000684- Comparisons using one of <, <=, >, >= between a complex instance and
685 a Fractions instance now raise TypeError instead of returning
686 True/False. This makes Fraction <=> complex comparisons consistent with
687 int <=> complex, float <=> complex, and complex <=> complex comparisons.
688
Antoine Pitrou39b35432010-03-23 00:25:54 +0000689- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
690 some methods (such as oss_mixer_device.fileno()) were not available.
691 Initial patch by Bertrand Janin.
692
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000693- Issue #8205: Remove the "Modules" directory from sys.path when Python is
694 running from the build directory (POSIX only).
695
Antoine Pitrou910bd512010-03-22 20:11:09 +0000696- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
697 didn't support chflags() (for example ZFS under FreeBSD). The error is
698 now silenced.
699
R. David Murrayca2edce2010-03-22 17:48:48 +0000700- Issue #7860: platform.uname now reports the correct 'machine' type
701 when Python is running in WOW64 mode on 64 bit Windows.
702
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000703- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
704 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
705 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000706
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000707- Issue #4282: Fix the main function of the profile module for a non-ASCII
708 script, open the file in binary mode and not in text mode with the default
709 (utf8) encoding.
710
Florent Xicluna54467e02010-03-21 12:29:50 +0000711- Issue #8179: Fix macpath.realpath() on a non-existing path.
712

716
Benjamin Peterson689a5582010-03-18 22:29:52 +0000717- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
718 detected.
719
Martin v. Löwis4b003072010-03-16 13:19:21 +0000720- Issue #6716/2: Backslash-replace error output in compilall.
721
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000722- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
723 with Tcl/Tk-8.5.
724
Matthias Klosec33b9022010-03-16 00:36:26 +0000725- Issue #8140: extend compileall to compile single files. Add -i option.

728 the locale.
729
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000730- The internals of the subprocess module on POSIX systems have been replaced
731 by an extension module (_posixsubprocess) so that the fork()+exec() can be
732 done safely without the possibility of deadlock in multithreaded applications.
733
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000734- subprocess.Popen now has restore_signals and start_new_session features.
735 The default of restore_signals=True is a new behavior compared to earlier
736 Python versions. This means that signals such as SIGPIPE are not ignored
737 by default in subprocesses launched by Python (Issue #1652).
738
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000739- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

749 the replacement were all bytes. Patch by Antoine Pitrou.
750
Gerhard Häringf9cee222010-03-05 15:20:03 +0000751- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
752 bugs and allows loading SQLite extensions from shared libraries.

Victor Stinnercee3ae82010-03-04 00:29:24 +0000757- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
758 reset also the pointer to the current pointer context.

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000768- Issue #691291: codecs.open() should not convert end of lines on reading and
769 writing.
770

785 to be ignored only to the first file. Noted by Bogdan Opanchuk.
786
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000787- Issue #7597: curses.use_env() can now be called before initscr().
788 Noted by Kan-Ru Chen.
789

796 bytecode file when it was less then 8 bytes.
797

799 exception of canonical and is_canonical) now accept instances of int
800 and long wherever a Decimal instance is accepted, and implicitly
801 convert that argument to Decimal. Previously only some arguments
802 were converted.
803
R. David Murray1f449142010-02-11 00:15:05 +0000804- Issue #7835: shelve should no longer produce mysterious warnings during
805 interpreter shutdown.
806
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000807- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
808 in XML processing instructions and comments. These raw characters are
809 allowed by the XML specification, and are necessary when outputting e.g.
810 PHP code in a processing instruction. Patch by Neil Muller.

822 type is specified. Patch by Brian Curtin.
823
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000824- Issue #6939: Fix file I/O objects in the `io` module to keep the original
825 file position when calling `truncate()`. It would previously change the
826 file position to the given argument, which goes against the tradition of
827 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
828
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000829- Issue #7610: Reworked implementation of the internal
830 :class:`zipfile.ZipExtFile` class used to represent files stored inside
831 an archive. The new implementation is significantly faster and can
832 be wrapped in a :class:`io.BufferedReader` object for more speedups.
833 It also solves an issue where interleaved calls to `read()` and
834 `readline()` give wrong results. Patch by Nir Aides.
835
Jesse Noller1f0b6582010-01-27 03:36:01 +0000836- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

838 the worker before that worker is terminated, and a new one created to
839 replace it.
840
Benjamin Petersond6326642010-01-27 02:25:58 +0000841- Issue #7792: Registering non-classes to ABCs raised an obscure error.
842

996
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000997- Issue #6816: runpy now provides a run_path function that allows Python code
998 to execute file paths that refer to source or compiled Python files as well
999 as zipfiles, directories and other valid sys.path entries that contain a
1000 __main__.py file. This allows applications that run other Python scripts to
1001 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001020 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001021 recursive locks as fast as regular non-recursive locks (previously,
1022 they were slower by 10x to 15x).

1042 reading from stdin so that existing input does not confuse it and
1043 lead to incorrect entry or an IOError. It also properly flushes it
1044 afterwards to avoid the terminal echoing the input afterwards on
1045 OSes such as Solaris.

R. David Murrayba311052009-12-04 00:09:14 +00001472 file in the Lib/test directory, which might be read-only for the

Antoine Pitrou060cee22009-11-13 16:29:04 +00001481- Issue #6551: test_zipimport could import and then destroy some modules of

1483 the road because the internally cached encoders and decoders would point
1484 to empty global variables.

1497 calling methods on the object.
1498
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001499- Issue #7222: Make thread "reaping" more reliable so that reference
1500 leak-chasing test runs give sensible results. The previous method of
1501 reaping threads could return successfully while some Thread objects were
1502 still referenced. This also introduces a new private function:
1503 :func:`_thread._count()`.
1504
R. David Murray27144602009-10-19 15:26:16 +00001505- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1506 longer runs the risk of causing the worker thread to fail.
1507
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001508- Issue #7055: test___all__ now greedily detects all modules which have an
1509 __all__ attribute, rather than using a hardcoded and incomplete list.
1510
R. David Murray0bc11ae2009-10-18 22:18:17 +00001511- Issue #7058: Added save/restore for things like sys.argv and cwd to

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001787*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001788
1789Core and Builtins
1790-----------------
1791
Mark Dickinson865e01a2009-05-07 16:37:01 +00001792- Issue #5914: Add new C API function PyOS_string_to_double, and
1793 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1794
Eric Smith741191f2009-05-06 13:08:15 +00001795- Issue #3382: float.__format__, complex.__format__, and %-formatting
1796 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1797 affects nan -> NAN and inf -> INF.
1798
Mark Hammond5a607a32009-05-06 08:04:54 +00001799- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1800 in all operations, including splitdrive, split, etc. splitunc() now issues
1801 a PendingDeprecation warning.
1802
Eric Smith63376222009-05-05 14:04:18 +00001803- Issue #5920: For float.__format__, change the behavior with the
1804 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1805 to be like 'g' but with at least one decimal point and with a
1806 default precision of 12. Previously, the behavior the same but with
1807 a default precision of 6. This more closely matches str(), and
1808 reduces surprises when adding alignment flags to the empty
1809 presentation type. This also affects the new complex.__format__ in
1810 the same way.
1811
Martin v. Löwis011e8422009-05-05 04:43:17 +00001812- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1813
R. David Murrayb18500d2009-05-04 22:59:07 +00001814- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1815 shadowed by classtype's, even if it was None. property now
1816 inserts the __doc__ into the subclass instance __dict__.
1817
Antoine Pitrou244651a2009-05-04 18:56:13 +00001818- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1819 sequences. Patch by Nick Barnes and Victor Stinner.
1820
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001821- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001822
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001823- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1824 received a new method, detach(). detach() disconnects the underlying stream
1825 from the buffer or text IO and returns it.
1826
Mark Dickinson33841c32009-05-01 15:37:04 +00001827- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1828 floats with absolute value over 1e50. Also remove length
1829 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1830 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001831
Eric Smith741191f2009-05-06 13:08:15 +00001832- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001833 format(complex(1, 2./3), '.5') now produces a sensible result.
1834
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001835- Issue #5864: Fix empty format code formatting for floats so that it
1836 never gives more than the requested number of significant digits.
1837
Eric Smith6dc46f52009-04-27 20:39:49 +00001838- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1839 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1840
Eric Smithcc32a112009-04-26 21:35:14 +00001841- Issue #5835: Deprecate PyOS_ascii_formatd.
1842
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001843- Issue #4971: Fix titlecase for characters that are their own
1844 titlecase, but not their own uppercase.
1845
Benjamin Peterson193152c2009-04-25 01:08:45 +00001846- Issue #5283: Setting __class__ in __del__ caused a segfault.
1847
Mark Dickinsonad476da2009-04-23 19:14:16 +00001848- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1849 z involves nans, infs or negative zeros.
1850
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001851- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001852
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001853- Issue #1869 (and many duplicates): make round(x, n) correctly
1854 rounded for a float x, by using the decimal <-> binary conversions
1855 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1856 consistently agrees with format(x, '.2f').
1857
Benjamin Petersonae937c02009-04-18 20:54:08 +00001858- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1859 some builtin types.
1860
Eric Smith0923d1d2009-04-16 20:16:10 +00001861- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1862
Eric Smith35e84722009-04-16 20:21:28 +00001863- Issue #5515: str.format() type 'n' combined with commas and leading
1864 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001865
1866- Implement PEP 378, Format Specifier for Thousands Separator, for
1867 floats.
1868
Mark Dickinson3370cce2009-04-17 22:40:53 +00001869- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001870 1e11, not 1e12. This avoids printing 13 significant digits in
1871 situations where only 12 of them are correct. Example problem
1872 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1873 long time.)
1874
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001875- Issue #1580: On most platforms, use a 'short' float repr: for a
1876 finite float x, repr(x) now outputs a string based on the shortest
1877 sequence of decimal digits that rounds to x. Previous behaviour was
1878 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001879 Another minor difference is that the new repr switches to
1880 exponential notation at 1e16 instead of the previous 1e17; this
1881 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001882
1883 There's a new sys attribute sys.float_repr_style, which takes
1884 the value 'short' to indicate that we're using short float repr,
1885 and 'legacy' if the short float repr isn't available for one
1886 reason or another.
1887
1888 The float repr change involves incorporating David Gay's 'perfect
1889 rounding' code into the Python core (it's in Python/dtoa.c). As a
1890 secondary consequence, all string-to-float and float-to-string
1891 conversions (including all float formatting operations) will be
1892 correctly rounded on these platforms.
1893
1894 See issue 1580 discussions for details of platforms for which
1895 this change does not apply.
1896
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001897- Issue #5759: float() didn't call __float__ on str subclasses.
1898
Georg Brandlabc38772009-04-12 15:51:51 +00001899- The string.maketrans() function is deprecated; there is a new static method
1900 maketrans() on the bytes and bytearray classes. This removes confusion about
1901 the types string.maketrans() is supposed to work with, and mirrors the
1902 methods available on the str class.
1903
R. David Murraydc6da8a2009-04-09 22:16:43 +00001904- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1905 its clarity and its speed.
1906
Matthias Klose091c7b12009-04-07 13:24:27 +00001907- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1908 to avoid compiler warnings.
1909
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001910- Issue #3739: The unicode-internal encoder now reports the number of characters
1911 consumed like any other encoder (instead of the number of bytes).

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002065- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2066 the end sys.path, for compatibility with the system install of Python.
2067
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002068- Issue #4688: Add a heuristic so that tuples and dicts containing only
2069 untrackable objects are not tracked by the garbage collector. This can
2070 reduce the size of collections and therefore the garbage collection overhead
2071 on long-running programs, depending on their particular use of datatypes.
2072
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002073- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2074 improve its performance. Long divisions and remainder operations
2075 are now between 50% and 150% faster.
2076
Mark Dickinsonbd792642009-03-18 20:06:12 +00002077- Issue #4258: Make it possible to use base 2**30 instead of base
2078 2**15 for the internal representation of integers, for performance
2079 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2080 --enable-big-digits option to configure, which overrides the
2081 default. Add sys.int_info structseq to provide information about
2082 the internal format.
2083
Mark Dickinson081dfee2009-03-18 14:47:41 +00002084- Issue #4474: PyUnicode_FromWideChar now converts characters outside

2090
Antoine Pitrou652e7072009-03-13 19:25:20 +00002091- Issue #5392: when a very low recursion limit was set, the interpreter would
2092 abort with a fatal error after the recursion limit was hit twice.
2093
Matthias Klose042f1332009-04-04 14:32:42 +00002094- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2140
Lars Gustäbel42e00912009-03-22 20:34:29 +00002141- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2142 forever on incomplete input. That caused tarfile.open() to hang when used
2143 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinson87ec0852009-02-09 17:15:59 +00002194- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2195 it now forces its argument to double before testing for infinity.
2196
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002197- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2198 returns a non-number type.
2199
Benjamin Peterson87618552009-02-08 15:00:52 +00002200- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002206
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002207- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002208 were suppressing all exceptions. These include list() and bytearray().
2209
Mark Dickinson1124e712009-01-28 21:25:58 +00002210- Issue #4707: round(x, n) now returns an integer if x is an integer.
2211 Previously it returned a float.
2212
Antoine Pitroub52ec782009-01-25 16:34:23 +00002213- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2214 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2215 evaluation loop is compiled with a new dispatch mechanism which gives
2216 speedups of up to 20%, depending on the system, on various benchmarks.
2217
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002218- Issue #4874: Most builtin decoders now reject unicode input.

2224
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002225- Issue #4838: When a module is deallocated, free the memory backing the
2226 optional module state data.
2227
Mark Dickinson8055afd2009-01-17 10:04:45 +00002228- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2229 type to (void *).
2230
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002231- Issue #4935: The overflow checking code in the expandtabs() method common
2232 to str, bytes and bytearray could be optimized away by the compiler, letting
2233 the interpreter segfault instead of raising an error.
2234
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002235- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2236 __next__ method.
2237
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002238- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2245
Antoine Pitrouab868312009-01-10 15:40:25 +00002246- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2247 common cases are optimized thanks to a dedicated fast path and a moderate
2248 amount of loop unrolling.
2249
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002250- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2251 collecting the oldest generation) so that allocating lots of objects without
2252 destroying them does not show quadratic performance. Based on a proposal by
2253 Martin von Löwis at
2254 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2255
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002256- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002257 having been closed (for instance, a read() call could return some
2258 previously buffered data). Patch by Dmitry Vasiliev.
2259
Antoine Pitrou05608432009-01-09 18:53:14 +00002260- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2261 flag to work properly. Furthermore, when specifying -u, the text stdout
2262 and stderr streams have line-by-line buffering enabled (the default being
2263 to buffer arbitrary chunks of data).
2264
Raymond Hettinger35631532009-01-09 03:58:09 +00002265- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2266 instead of ints (reducing its size from 4 to 8 times thereby reducing
2267 Python's overall memory).
2268
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002269- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2270 an existing .py counterpart, override the co_filename attributes of all
2271 code objects if the original filename is obsolete (which can happen if the
2272 file has been renamed, moved, or if it is accessed through different paths).
2273 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2274
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002275- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2276 one byte. Also fixes the meaning of len() so that it returns the number of
2277 items, rather than the size in bytes.
2278
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002279- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2280
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002281- Issue #4747: When the terminal does not use utf-8, executing a script with
2282 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2283
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002284- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002285 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002286
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002287- Issue #3680: Reference cycles created through a dict, set or deque iterator
2288 did not get collected.
2289
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002290- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2291 where the tp_hash and tp_dict slots are both NULL.
2292
Georg Brandlccc47b62008-12-28 11:44:14 +00002293- Issue #4759: None is now allowed as the first argument of
2294 bytearray.translate(). It was always allowed for bytes.translate().
2295
Skip Montanaro80072cb2008-12-23 03:51:14 +00002296- Added test case to ensure attempts to read from a file opened for writing
2297 fail.
2298
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002299- Issue #3106: Speedup some comparisons (str/str and int/int).

2302 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2303
Antoine Pitrou621601a2008-12-17 23:18:19 +00002304- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2305 print elapsed times, not only when some objects are uncollectable /
2306 unreachable. Original patch by Neil Schemenauer.
2307
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002308- Issue #3439: Add a bit_length method to int.
2309
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002310- Issue #2173: When getting device encoding, check that return value of
2311 nl_langinfo is not the empty string. This was causing silent build
2312 failures on OS X.
2313
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002314- Issue #4597: Fixed several opcodes that weren't always propagating
2315 exceptions.
2316
2317- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002318 context manager returns a value that cannot be converted to a bool.
2319
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002320- Issue #4445: Replace "sizeof(PyBytesObject)" with
2321 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2322 bytes instances. On a typical machine this saves 3 bytes of memory
2323 (on average) per allocation of a bytes instance.
2324
Christian Heimesa872de52008-12-05 08:26:55 +00002325- Issue #4533: File read operation was dreadfully slow due to a slowly
2326 growing read buffer. Fixed by using the same growth rate algorithm as
2327 Python 2.x.
2328
Antoine Pitrou5504e892008-12-06 21:27:53 +00002329- Issue #4509: Various issues surrounding resize of bytearray objects to
2330 which there are buffer exports (e.g. memoryview instances).
2331
Georg Brandlf9734072008-12-07 15:30:06 +00002332- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2333 method on file objects with closefd=False. The file descriptor is still
2334 kept open but the file object behaves like a closed file. The ``FileIO``
2335 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002336
Antoine Pitroubc420402008-12-07 20:14:49 +00002337- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2666
Antoine Pitrou08838b62009-01-21 00:55:13 +00002667- Issue #5008: When a file is opened in append mode with the new IO library,
2668 do an explicit seek to the end of file (so that e.g. tell() returns the
2669 file size rather than 0). This is consistent with the behaviour of the
2670 traditional 2.x file object.

Antoine Pitrou88909542009-06-29 13:54:42 +00002949- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2950 regression tests in parallel, shortening the total runtime.
2951
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002952- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2953 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2954 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2955 skip the tests if DISPLAY is defined but can't be used.
2956
R. David Murraya21e4ca2009-03-31 23:16:50 +00002957- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002958 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002959 from test support, which does the conversion.
2960
Guilherme Polo9de29af2009-01-28 20:40:48 +00002961- Issue #5083: New 'gui' resource for regrtest.
