10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Mark Dickinsondc787d22010-05-23 13:33:13 +000015- Issue #8188: Introduce a new scheme for computing hashes of numbers
16 (instances of int, float, complex, decimal.Decimal and
17 fractions.Fraction) that makes it easy to maintain the invariant
18 that hash(x) == hash(y) whenever x and y have equal value.
19
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000020- Issue #8748: Fix two issues with comparisons between complex and integer
21 objects. (1) The comparison could incorrectly return True in some cases
22 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
23 (2) The comparison raised an OverflowError for large integers, leading
24 to unpredictable exceptions when combining integers and complex objects
25 in sets or dicts.
26
Victor Stinner7d79b8b2010-05-19 20:40:50 +000027- Issue #8766: Initialize _warnings module before importing the first module.
28 Fix a crash if an empty directory called "encodings" exists in sys.path.
29
Victor Stinner9ca9c252010-05-19 16:53:30 +000030- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
31 encoding and surrogateespace error handler instead of the locale encoding to
32 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
33
Victor Stinner372ac5e2010-05-17 01:26:01 +000034- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
35 (instead of strict) error handler to escape surrogates
36
Victor Stinnerae6265f2010-05-15 16:27:27 +000037- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
38 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000039 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
40 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000041
Victor Stinner59e62db2010-05-15 13:14:32 +000042- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
43 error handler, not only the default error handler (strict)
44
Victor Stinnerb744ba12010-05-15 12:27:16 +000045- Issue #8610: Load file system codec at startup, and display a fatal error on
46 failure. Set the file system encoding to utf-8 (instead of None) if getting
47 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
48
Victor Stinner0964ee12010-04-30 16:48:45 +000049- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
50 PyUnicode_FromString() to support surrogates in the filename and use the
51 right encoding
52
Georg Brandl8569e582010-05-19 20:57:08 +000053- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
54
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000055- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
56
Benjamin Petersonfb886362010-04-24 18:21:17 +000057- Issue #8419: Prevent the dict constructor from accepting non-string keyword
58 arguments.
59
Victor Stinner14284c22010-04-23 12:02:30 +000060- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
61 indirectly Python signal handlers anymore because mywrite() ignores
62 exceptions (KeyboardInterrupt)
63
Victor Stinner31be90b2010-04-22 19:38:16 +000064- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
65 unicode string (eg. backslashreplace)
66
Victor Stinnerdcb24032010-04-22 12:08:36 +000067- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
68 you have to convert your bytearray filenames to bytes
69
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000070- Issue #7332: Remove the 16KB stack-based buffer in
71 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
72 benefit compared to the dynamic memory allocation fallback. Patch by
73 Charles-François Natali.
74
Benjamin Peterson8380dd52010-04-16 22:51:37 +000075- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
76 passed to bytes or bytearray.
77
Philip Jenvey0805ca32010-04-07 04:04:10 +000078- Issue #7301: Add environment variable $PYTHONWARNINGS.
79
Benjamin Petersond856ab62010-04-06 21:55:16 +000080- Issue #8329: Don't return the same lists from select.select when no fds are
81 changed.
82
Mark Dickinson3318d292010-04-06 16:53:17 +000083- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
84 on 64-bit machines. The shift count for either left or right shift is
85 permitted to be up to sys.maxsize.
86
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000087- Ensure that tokenization of identifiers is not affected by locale.

Marc-André Lemburg177ab082010-05-05 13:32:59 +000093- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in
94 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +000095
Victor Stinner120c2122010-03-25 00:30:28 +000096- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
97 is unknown
98
Victor Stinner808fc0a2010-03-22 12:50:40 +000099- Issue #1583863: An str subclass can now override the __str__ method
100
Mark Dickinsond59b4162010-03-13 11:34:40 +0000101- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
102 PyMemberDefs could produce an internal error; raise TypeError instead.
103
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000104- Issue #7845: Rich comparison methods on the complex type now return
105 NotImplemented rather than raising a TypeError when comparing with an
106 incompatible type; this allows user-defined classes to implement their own
107 comparisons with complex.
108
Victor Stinner52f6dd72010-03-12 14:45:56 +0000109- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
110 (SIGINT). If an error occurs while importing the site module, the error is
111 printed and Python exits. Initialize the GIL before importing the site
112 module.
113
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000114- Issue #7173: Generator finalization could invalidate sys.exc_info().

123
Larry Hastings1373a072010-02-24 22:49:58 +0000124- Issue #5939: Add additional runtime checking to ensure a valid capsule
125 in Modules/_ctypes/callproc.c.
126
Eric Smith0facd772010-02-24 15:42:29 +0000127- Issue #7309: Fix unchecked attribute access when converting
128 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
129 strings.
130

132 0 padding.
133
Eric Smith4e260c52010-02-22 18:54:44 +0000134- Issue #7988: Fix default alignment to be right aligned for
135 complex.__format__. Now it matches other numeric types.

138 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
139 and PyOS_string_to_double instead. See issue #5835 for the original
140 deprecations.
141
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000142- Issue #7385: Fix a crash in `MemoryView_FromObject` when
143 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
144
Mark Dickinsonbc099642010-01-29 17:27:24 +0000145- Issue #7788: Fix an interpreter crash produced by deleting a list
146 slice with very large step value.
147
Eric Smithf7bb5782010-01-27 00:44:57 +0000148- Issue #7766: Change sys.getwindowsversion() return value to a named
149 tuple and add the additional members returned in an OSVERSIONINFOEX
150 structure. The new members are service_pack_major, service_pack_minor,
151 suite_mask, and product_type.
152
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000153- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
154 could crash in many places because of the PyByteArray_AS_STRING() macro
155 returning NULL. The macro now returns a statically allocated empty
156 string instead.
157
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000158- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
159 where the right hand operand is a set of constants, by turning the set into
160 a frozenset and pre-building it as a constant. The comparison operation
161 is made against the constant instead of building a new set each time it is
162 executed (a similar optimization already existed which turned a list of
163 constants into a pre-built tuple). Patch and additional tests by Dave
164 Malcolm.
165
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000166- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
167 methods of bytes, bytearray and unicode objects by using a common
168 implementation based on stringlib's fast search. Patch by Florent Xicluna.
169
Mark Dickinson45b63652010-01-16 18:10:25 +0000170- Issue #7632: Fix various str -> float conversion bugs present in 2.7
171 alpha 2, including: (1) a serious 'wrong output' bug that could
172 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
173 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000174 strings corresponding to subnormal values, (3) a memory leak for
175 some values large enough to cause overflow, and (4) a number of
176 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000177
Benjamin Petersonaea44282010-01-04 01:10:28 +0000178- The __complex__ method is now looked up on the class of instances to make it
179 consistent with other special methods.
180

182 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
183
Benjamin Petersond12362a2009-12-30 19:44:54 +0000184- Issue #7604: Deleting an unset slotted attribute did not raise an
185 AttributeError.
186
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000187- Issue #7534: Fix handling of IEEE specials (infinities, nans,
188 negative zero) in ** operator. The behaviour now conforms to that
189 described in C99 Annex F.
190
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000191- Issue #1811: improve accuracy and cross-platform consistency for
192 true division of integers: the result of a/b is now correctly
193 rounded for ints a and b (at least on IEEE 754 platforms), and in
194 particular does not depend on the internal representation of an int.
195
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000196- Issue #6834: replace the implementation for the 'python' and 'pythonw'
197 executables on OSX.
198
199 These executables now work properly with the arch(1) command:
200 ``arch -ppc python`` will start a universal binary version of python
201 in PPC mode (unlike previous releases).
202
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000203- Issue #7466: segmentation fault when the garbage collector is called
204 in the middle of populating a tuple. Patch by Florent Xicluna.

219
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000220- Issue #7298: fixes for range and reversed(range(...)). Iteration
221 over range(a, b, c) incorrectly gave an empty iterator when a, b and
222 c fit in C long but the length of the range did not. Also fix
223 several cases where reversed(range(a, b, c)) gave wrong results, and
224 fix a refleak for reversed(range(a, b, c)) with large arguments.
225
Raymond Hettingerfc438512009-11-01 20:55:33 +0000226- Issue #7244: itertools.izip_longest() no longer ignores exceptions

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

Mark Dickinsonc69160e2010-05-04 14:35:33 +0000489- Issue #8567: Fix precedence of signals in Decimal module: when a
490 Decimal operation raises multiple signals and more than one of those
491 signals is trapped, the specification determines the order in which
492 the signals should be handled. In many cases this order wasn't
493 being followed, leading to the wrong Python exception being raised.

535
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000536- Issue #5103: SSL handshake would ignore the socket timeout and block

R. David Murrayd48739f2010-04-14 18:59:18 +0000607- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
608
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000609- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
610 module now takes an optional timeout argument in seconds. Timeout support
611 relies on the system threading library, so as to avoid a semi-busy wait
612 loop.
613
Victor Stinner485fb562010-04-13 11:07:24 +0000614- Issue #8383: pickle and pickletools use surrogatepass error handler when
615 encoding unicode as utf8 to support lone surrogates and stay compatible with
616 Python 2.x and 3.0
617
R. David Murrayb2416e52010-04-12 16:58:02 +0000618- Issue #7585: difflib context and unified diffs now place a tab between
619 filename and date, conforming to the 'standards' they were originally
620 designed to follow. This improves compatibility with patch tools.
621
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000622- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
623 character sets will now consistently use a Content-Transfer-Encoding of
624 7bit rather than sometimes being marked as 8bit.
625
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000626- Issue #8375: test_distutils now checks if the temporary directory are still
627 present before it cleans them.
628
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000629- Issue #8374: Update the internal alias table in the :mod:`locale` module
630 to cover recent locale changes and additions.
631
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000632- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
633 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
634 and `ssl.OPENSSL_VERSION_NUMBER`.
635
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000636- Add functools.total_ordering() and functools.cmp_to_key().
637
Mark Dickinson089b00c2010-04-03 15:51:03 +0000638- Issue #8257: The Decimal construct now accepts a float instance
639 directly, converting that float to a Decimal of equal value:
640
641 >>> Decimal(1.1)
642 Decimal('1.100000000000000088817841970012523233890533447265625')
643
Mark Dickinson98127c32010-04-03 11:18:52 +0000644- Issue #8294: The Fraction constructor now accepts Decimal and float
645 instances directly.
646
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000647- Issue #7279: Comparisons involving a Decimal signaling NaN now
648 signal InvalidOperation instead of returning False. (Comparisons
649 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
650 are now hashable; Decimal signaling NaNs remain unhashable.
651
652- Issue #2531: Comparison operations between floats and Decimal
653 instances now return a result based on the numeric values of the
654 operands; previously they returned an arbitrary result based on
655 the relative ordering of id(float) and id(Decimal).
656
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000657- Added a subtract() method to collections.Counter().
658
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000659- Issue #8233: When run as a script, py_compile.py optionally takes a single
660 argument `-` which tells it to read files to compile from stdin. Each line
661 is read on demand and the named file is compiled immediately. (Original
662 patch by Piotr Ożarowski).
663
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000664- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
665 form feed (0x0C) are now considered linebreaks, as specified in Unicode
666 Standard Annex #14. See issue #7643.
667 http://www.unicode.org/reports/tr14/
668
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000669- Comparisons using one of <, <=, >, >= between a complex instance and
670 a Fractions instance now raise TypeError instead of returning
671 True/False. This makes Fraction <=> complex comparisons consistent with
672 int <=> complex, float <=> complex, and complex <=> complex comparisons.
673
Antoine Pitrou39b35432010-03-23 00:25:54 +0000674- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
675 some methods (such as oss_mixer_device.fileno()) were not available.
676 Initial patch by Bertrand Janin.
677
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000678- Issue #8205: Remove the "Modules" directory from sys.path when Python is
679 running from the build directory (POSIX only).
680
Antoine Pitrou910bd512010-03-22 20:11:09 +0000681- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
682 didn't support chflags() (for example ZFS under FreeBSD). The error is
683 now silenced.
684
R. David Murrayca2edce2010-03-22 17:48:48 +0000685- Issue #7860: platform.uname now reports the correct 'machine' type
686 when Python is running in WOW64 mode on 64 bit Windows.
687
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000688- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
689 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
690 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000691
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000692- Issue #4282: Fix the main function of the profile module for a non-ASCII
693 script, open the file in binary mode and not in text mode with the default
694 (utf8) encoding.
695
Florent Xicluna54467e02010-03-21 12:29:50 +0000696- Issue #8179: Fix macpath.realpath() on a non-existing path.
697
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000698- Issue #8024: Update the Unicode database to 5.2.
699
Benjamin Peterson00888932010-03-18 22:37:38 +0000700- Issue #8168: py_compile now handles files with utf-8 BOMS.
701
Benjamin Peterson689a5582010-03-18 22:29:52 +0000702- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
703 detected.
704
Martin v. Löwis4b003072010-03-16 13:19:21 +0000705- Issue #6716/2: Backslash-replace error output in compilall.
706
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000707- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
708 with Tcl/Tk-8.5.
709
Matthias Klosec33b9022010-03-16 00:36:26 +0000710- Issue #8140: extend compileall to compile single files. Add -i option.
711
Matthias Klose82f60912010-03-15 13:46:04 +0000712- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
713 the locale.
714
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000715- The internals of the subprocess module on POSIX systems have been replaced
716 by an extension module (_posixsubprocess) so that the fork()+exec() can be
717 done safely without the possibility of deadlock in multithreaded applications.
718
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000719- subprocess.Popen now has restore_signals and start_new_session features.
720 The default of restore_signals=True is a new behavior compared to earlier
721 Python versions. This means that signals such as SIGPIPE are not ignored
722 by default in subprocesses launched by Python (Issue #1652).
723
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000724- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
725 cElementTree module is updated too.
726

734 the replacement were all bytes. Patch by Antoine Pitrou.
735
Gerhard Häringf9cee222010-03-05 15:20:03 +0000736- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
737 bugs and allows loading SQLite extensions from shared libraries.
738

Victor Stinnercee3ae82010-03-04 00:29:24 +0000742- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
743 reset also the pointer to the current pointer context.

752
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000753- Issue #691291: codecs.open() should not convert end of lines on reading and
754 writing.
755
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000756- Issue #7869: logging: improved diagnostic for format-time errors.

Thomas Heller5117b0b2010-02-23 20:25:02 +0000764- Issue #7959: ctypes callback functions are now registered correctly
Ezio Melotti8b1458b2010-02-24 16:55:43 +0000765 with the cycle garbage collector.
Thomas Heller5117b0b2010-02-23 20:25:02 +0000766

770 to be ignored only to the first file. Noted by Bogdan Opanchuk.
771
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000772- Issue #7597: curses.use_env() can now be called before initscr().
773 Noted by Kan-Ru Chen.
774

781 bytecode file when it was less then 8 bytes.
782
Mark Dickinson84230a12010-02-18 14:49:50 +0000783- Issue #7633: In the decimal module, Context class methods (with the
784 exception of canonical and is_canonical) now accept instances of int
785 and long wherever a Decimal instance is accepted, and implicitly
786 convert that argument to Decimal. Previously only some arguments
787 were converted.
788
R. David Murray1f449142010-02-11 00:15:05 +0000789- Issue #7835: shelve should no longer produce mysterious warnings during
790 interpreter shutdown.
791
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000792- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
793 in XML processing instructions and comments. These raw characters are
794 allowed by the XML specification, and are necessary when outputting e.g.
795 PHP code in a processing instruction. Patch by Neil Muller.
796
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000797- Issue #6233: ElementTree failed converting unicode characters to XML

803
Antoine Pitroub6375f12010-02-04 20:23:24 +0000804- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

807 type is specified. Patch by Brian Curtin.
808
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000809- Issue #6939: Fix file I/O objects in the `io` module to keep the original
810 file position when calling `truncate()`. It would previously change the
811 file position to the given argument, which goes against the tradition of
812 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
813
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000814- Issue #7610: Reworked implementation of the internal
815 :class:`zipfile.ZipExtFile` class used to represent files stored inside
816 an archive. The new implementation is significantly faster and can
817 be wrapped in a :class:`io.BufferedReader` object for more speedups.
818 It also solves an issue where interleaved calls to `read()` and
819 `readline()` give wrong results. Patch by Nir Aides.
820
Jesse Noller1f0b6582010-01-27 03:36:01 +0000821- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
822 allowing for a maximum number of tasks within the pool to be completed by
823 the worker before that worker is terminated, and a new one created to
824 replace it.
825
Benjamin Petersond6326642010-01-27 02:25:58 +0000826- Issue #7792: Registering non-classes to ABCs raised an obscure error.
827
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000828- Issue #7785: Don't accept bytes in FileIO.write().

Ezio Melotti38f00332010-01-25 12:39:47 +0000830- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
831
Benjamin Peterson25001472010-01-25 03:37:42 +0000832- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

884 Initial patch by Brian Curtin.
885
Tarek Ziadéc60ea322009-12-21 23:12:41 +0000886- Issue #7556: Make sure Distutils' msvc9compile reads and writes the
Victor Stinnere125f132010-05-15 21:04:43 +0000887 MSVC XML Manifest file in text mode so string patterns can be used

935 ownership when the group is not forced, because the group may be different
936 from the user's group and inherit from its container when the test is run.
937

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000982- Issue #6816: runpy now provides a run_path function that allows Python code
983 to execute file paths that refer to source or compiled Python files as well
984 as zipfiles, directories and other valid sys.path entries that contain a
985 __main__.py file. This allows applications that run other Python scripts to

Victor Stinnere125f132010-05-15 21:04:43 +00001005 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001006 recursive locks as fast as regular non-recursive locks (previously,
1007 they were slower by 10x to 15x).

1027 reading from stdin so that existing input does not confuse it and
1028 lead to incorrect entry or an IOError. It also properly flushes it
1029 afterwards to avoid the terminal echoing the input afterwards on
1030 OSes such as Solaris.

1217 algorithm with an improved 'binary-split' algorithm that uses fewer
1218 multiplications and allows many of the multiplications to be
1219 performed using plain C integer arithmetic instead of PyLong
1220 arithmetic. Also uses a lookup table for small arguments.

1293 gcc. (Optimization was unintentionally turned on in gcc

1478
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001479- Issue #7222: Make thread "reaping" more reliable so that reference
1480 leak-chasing test runs give sensible results. The previous method of
1481 reaping threads could return successfully while some Thread objects were
1482 still referenced. This also introduces a new private function:

1769Core and Builtins
1770-----------------
1771
Mark Dickinson865e01a2009-05-07 16:37:01 +00001772- Issue #5914: Add new C API function PyOS_string_to_double, and
1773 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1774
Eric Smith741191f2009-05-06 13:08:15 +00001775- Issue #3382: float.__format__, complex.__format__, and %-formatting
1776 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1777 affects nan -> NAN and inf -> INF.
1778
Mark Hammond5a607a32009-05-06 08:04:54 +00001779- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1780 in all operations, including splitdrive, split, etc. splitunc() now issues
1781 a PendingDeprecation warning.
1782
Eric Smith63376222009-05-05 14:04:18 +00001783- Issue #5920: For float.__format__, change the behavior with the
1784 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1785 to be like 'g' but with at least one decimal point and with a
1786 default precision of 12. Previously, the behavior the same but with
1787 a default precision of 6. This more closely matches str(), and
1788 reduces surprises when adding alignment flags to the empty
1789 presentation type. This also affects the new complex.__format__ in
1790 the same way.
1791
Martin v. Löwis011e8422009-05-05 04:43:17 +00001792- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1793
R. David Murrayb18500d2009-05-04 22:59:07 +00001794- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1795 shadowed by classtype's, even if it was None. property now
1796 inserts the __doc__ into the subclass instance __dict__.
1797
Antoine Pitrou244651a2009-05-04 18:56:13 +00001798- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1799 sequences. Patch by Nick Barnes and Victor Stinner.
1800
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001801- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001802
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001803- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1804 received a new method, detach(). detach() disconnects the underlying stream
1805 from the buffer or text IO and returns it.
1806
Mark Dickinson33841c32009-05-01 15:37:04 +00001807- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1808 floats with absolute value over 1e50. Also remove length
1809 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1810 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001811
Eric Smith741191f2009-05-06 13:08:15 +00001812- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001813 format(complex(1, 2./3), '.5') now produces a sensible result.
1814
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001815- Issue #5864: Fix empty format code formatting for floats so that it
1816 never gives more than the requested number of significant digits.
1817
Eric Smith6dc46f52009-04-27 20:39:49 +00001818- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1819 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1820
Eric Smithcc32a112009-04-26 21:35:14 +00001821- Issue #5835: Deprecate PyOS_ascii_formatd.
1822
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001823- Issue #4971: Fix titlecase for characters that are their own
1824 titlecase, but not their own uppercase.
1825
Benjamin Peterson193152c2009-04-25 01:08:45 +00001826- Issue #5283: Setting __class__ in __del__ caused a segfault.
1827
Mark Dickinsonad476da2009-04-23 19:14:16 +00001828- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1829 z involves nans, infs or negative zeros.
1830
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001831- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001832
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001833- Issue #1869 (and many duplicates): make round(x, n) correctly
1834 rounded for a float x, by using the decimal <-> binary conversions
1835 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1836 consistently agrees with format(x, '.2f').
1837
Benjamin Petersonae937c02009-04-18 20:54:08 +00001838- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1839 some builtin types.
1840
Eric Smith0923d1d2009-04-16 20:16:10 +00001841- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1842
Eric Smith35e84722009-04-16 20:21:28 +00001843- Issue #5515: str.format() type 'n' combined with commas and leading
1844 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001845
1846- Implement PEP 378, Format Specifier for Thousands Separator, for
1847 floats.
1848
Mark Dickinson3370cce2009-04-17 22:40:53 +00001849- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001850 1e11, not 1e12. This avoids printing 13 significant digits in
1851 situations where only 12 of them are correct. Example problem
1852 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1853 long time.)
1854
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001855- Issue #1580: On most platforms, use a 'short' float repr: for a
1856 finite float x, repr(x) now outputs a string based on the shortest
1857 sequence of decimal digits that rounds to x. Previous behaviour was
1858 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001859 Another minor difference is that the new repr switches to
1860 exponential notation at 1e16 instead of the previous 1e17; this
1861 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001862
1863 There's a new sys attribute sys.float_repr_style, which takes
1864 the value 'short' to indicate that we're using short float repr,
1865 and 'legacy' if the short float repr isn't available for one
1866 reason or another.
1867
1868 The float repr change involves incorporating David Gay's 'perfect
1869 rounding' code into the Python core (it's in Python/dtoa.c). As a
1870 secondary consequence, all string-to-float and float-to-string
1871 conversions (including all float formatting operations) will be
1872 correctly rounded on these platforms.
1873
1874 See issue 1580 discussions for details of platforms for which
1875 this change does not apply.
1876
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001877- Issue #5759: float() didn't call __float__ on str subclasses.
1878
Georg Brandlabc38772009-04-12 15:51:51 +00001879- The string.maketrans() function is deprecated; there is a new static method
1880 maketrans() on the bytes and bytearray classes. This removes confusion about
1881 the types string.maketrans() is supposed to work with, and mirrors the
1882 methods available on the str class.
1883
R. David Murraydc6da8a2009-04-09 22:16:43 +00001884- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1885 its clarity and its speed.
1886
Matthias Klose091c7b12009-04-07 13:24:27 +00001887- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1888 to avoid compiler warnings.
1889
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001890- Issue #3739: The unicode-internal encoder now reports the number of characters
1891 consumed like any other encoder (instead of the number of bytes).

1906
Vinay Sajipaffbd872009-06-11 10:11:47 +00001907- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1971 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1972 dispatcher now has an 'ignore_log_types' attribute for suppressing
1973 log messages, which is set to 'warning' by default.
1974

2047
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002048- Issue #4688: Add a heuristic so that tuples and dicts containing only
2049 untrackable objects are not tracked by the garbage collector. This can
2050 reduce the size of collections and therefore the garbage collection overhead
2051 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002174- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2175 it now forces its argument to double before testing for infinity.
2176
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002177- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002186
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002187- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002188 were suppressing all exceptions. These include list() and bytearray().
2189
Mark Dickinson1124e712009-01-28 21:25:58 +00002190- Issue #4707: round(x, n) now returns an integer if x is an integer.
2191 Previously it returned a float.
2192
Antoine Pitroub52ec782009-01-25 16:34:23 +00002193- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2194 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2195 evaluation loop is compiled with a new dispatch mechanism which gives
2196 speedups of up to 20%, depending on the system, on various benchmarks.
2197
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002198- Issue #4874: Most builtin decoders now reject unicode input.

2204
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002205- Issue #4838: When a module is deallocated, free the memory backing the
2206 optional module state data.
2207
Mark Dickinson8055afd2009-01-17 10:04:45 +00002208- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2209 type to (void *).
2210
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002211- Issue #4935: The overflow checking code in the expandtabs() method common
2212 to str, bytes and bytearray could be optimized away by the compiler, letting
2213 the interpreter segfault instead of raising an error.
2214
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002215- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2216 __next__ method.
2217
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002218- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2219 function no longer attempt to call the __long__ slot to convert an object
2220 to an integer. Only the __int__ and __trunc__ slots are examined.
2221
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002222- Issue #4893: Use NT threading on CE.
2223

2225
Antoine Pitrouab868312009-01-10 15:40:25 +00002226- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2227 common cases are optimized thanks to a dedicated fast path and a moderate
2228 amount of loop unrolling.
2229
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002230- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2231 collecting the oldest generation) so that allocating lots of objects without
2232 destroying them does not show quadratic performance. Based on a proposal by
2233 Martin von Löwis at
2234 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2235
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002236- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002237 having been closed (for instance, a read() call could return some
2238 previously buffered data). Patch by Dmitry Vasiliev.
2239
Antoine Pitrou05608432009-01-09 18:53:14 +00002240- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2241 flag to work properly. Furthermore, when specifying -u, the text stdout
2242 and stderr streams have line-by-line buffering enabled (the default being
2243 to buffer arbitrary chunks of data).
2244
Raymond Hettinger35631532009-01-09 03:58:09 +00002245- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2246 instead of ints (reducing its size from 4 to 8 times thereby reducing
2247 Python's overall memory).
2248
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002249- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2250 an existing .py counterpart, override the co_filename attributes of all
2251 code objects if the original filename is obsolete (which can happen if the
2252 file has been renamed, moved, or if it is accessed through different paths).
2253 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2254
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002255- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2256 one byte. Also fixes the meaning of len() so that it returns the number of
2257 items, rather than the size in bytes.
2258
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002259- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2260
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002261- Issue #4747: When the terminal does not use utf-8, executing a script with
2262 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2263
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002264- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002265 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002266
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002267- Issue #3680: Reference cycles created through a dict, set or deque iterator
2268 did not get collected.
2269
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002270- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2271 where the tp_hash and tp_dict slots are both NULL.
2272
Georg Brandlccc47b62008-12-28 11:44:14 +00002273- Issue #4759: None is now allowed as the first argument of
2274 bytearray.translate(). It was always allowed for bytes.translate().
2275
Skip Montanaro80072cb2008-12-23 03:51:14 +00002276- Added test case to ensure attempts to read from a file opened for writing
2277 fail.
2278
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002279- Issue #3106: Speedup some comparisons (str/str and int/int).

2282 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2283
Antoine Pitrou621601a2008-12-17 23:18:19 +00002284- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2285 print elapsed times, not only when some objects are uncollectable /
2286 unreachable. Original patch by Neil Schemenauer.
2287
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002288- Issue #3439: Add a bit_length method to int.
2289
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002290- Issue #2173: When getting device encoding, check that return value of
2291 nl_langinfo is not the empty string. This was causing silent build
2292 failures on OS X.
2293
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002294- Issue #4597: Fixed several opcodes that weren't always propagating
2295 exceptions.
2296
2297- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002298 context manager returns a value that cannot be converted to a bool.
2299
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002300- Issue #4445: Replace "sizeof(PyBytesObject)" with
2301 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2302 bytes instances. On a typical machine this saves 3 bytes of memory
2303 (on average) per allocation of a bytes instance.
2304
Christian Heimesa872de52008-12-05 08:26:55 +00002305- Issue #4533: File read operation was dreadfully slow due to a slowly
2306 growing read buffer. Fixed by using the same growth rate algorithm as
2307 Python 2.x.
2308
Antoine Pitrou5504e892008-12-06 21:27:53 +00002309- Issue #4509: Various issues surrounding resize of bytearray objects to
2310 which there are buffer exports (e.g. memoryview instances).
2311
Georg Brandlf9734072008-12-07 15:30:06 +00002312- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2313 method on file objects with closefd=False. The file descriptor is still
2314 kept open but the file object behaves like a closed file. The ``FileIO``
2315 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002317- Issue #4569: Interpreter crash when mutating a memoryview with an item size

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002324- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2325 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2326 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2327 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00002929- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2930 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002932- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2933 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2934 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2935 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002937- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002938 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002939 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002941- Issue #5083: New 'gui' resource for regrtest.
