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

391 pymalloc allocator will be automatically disabled when running under
392 Valgrind. This gives improved memory leak detection when running
393 under Valgrind, while taking advantage of pymalloc at other times.

620
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000621- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
622 module now takes an optional timeout argument in seconds. Timeout support
623 relies on the system threading library, so as to avoid a semi-busy wait
624 loop.
625
Victor Stinner485fb562010-04-13 11:07:24 +0000626- Issue #8383: pickle and pickletools use surrogatepass error handler when
627 encoding unicode as utf8 to support lone surrogates and stay compatible with
628 Python 2.x and 3.0
629
R. David Murrayb2416e52010-04-12 16:58:02 +0000630- Issue #7585: difflib context and unified diffs now place a tab between
631 filename and date, conforming to the 'standards' they were originally
632 designed to follow. This improves compatibility with patch tools.
633
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000634- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
635 character sets will now consistently use a Content-Transfer-Encoding of
636 7bit rather than sometimes being marked as 8bit.
637
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000638- Issue #8375: test_distutils now checks if the temporary directory are still
639 present before it cleans them.
640
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000641- Issue #8374: Update the internal alias table in the :mod:`locale` module
642 to cover recent locale changes and additions.
643

645 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
646 and `ssl.OPENSSL_VERSION_NUMBER`.
647
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000648- Add functools.total_ordering() and functools.cmp_to_key().
649
Mark Dickinson089b00c2010-04-03 15:51:03 +0000650- Issue #8257: The Decimal construct now accepts a float instance
651 directly, converting that float to a Decimal of equal value:
652
653 >>> Decimal(1.1)
654 Decimal('1.100000000000000088817841970012523233890533447265625')
655
Mark Dickinson98127c32010-04-03 11:18:52 +0000656- Issue #8294: The Fraction constructor now accepts Decimal and float
657 instances directly.
658
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000659- Issue #7279: Comparisons involving a Decimal signaling NaN now
660 signal InvalidOperation instead of returning False. (Comparisons
661 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
662 are now hashable; Decimal signaling NaNs remain unhashable.
663
664- Issue #2531: Comparison operations between floats and Decimal
665 instances now return a result based on the numeric values of the
666 operands; previously they returned an arbitrary result based on
667 the relative ordering of id(float) and id(Decimal).
668
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000669- Added a subtract() method to collections.Counter().
670
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000671- Issue #8233: When run as a script, py_compile.py optionally takes a single
672 argument `-` which tells it to read files to compile from stdin. Each line
673 is read on demand and the named file is compiled immediately. (Original
674 patch by Piotr Ożarowski).
675
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000676- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
677 form feed (0x0C) are now considered linebreaks, as specified in Unicode
678 Standard Annex #14. See issue #7643.
679 http://www.unicode.org/reports/tr14/
680
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000681- Comparisons using one of <, <=, >, >= between a complex instance and
682 a Fractions instance now raise TypeError instead of returning
683 True/False. This makes Fraction <=> complex comparisons consistent with
684 int <=> complex, float <=> complex, and complex <=> complex comparisons.
685
Antoine Pitrou39b35432010-03-23 00:25:54 +0000686- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

688 Initial patch by Bertrand Janin.
689
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000690- Issue #8205: Remove the "Modules" directory from sys.path when Python is
691 running from the build directory (POSIX only).
692
Antoine Pitrou910bd512010-03-22 20:11:09 +0000693- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
694 didn't support chflags() (for example ZFS under FreeBSD). The error is
695 now silenced.
696
R. David Murrayca2edce2010-03-22 17:48:48 +0000697- Issue #7860: platform.uname now reports the correct 'machine' type
698 when Python is running in WOW64 mode on 64 bit Windows.
699
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000700- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
701 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
702 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000703
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000704- Issue #4282: Fix the main function of the profile module for a non-ASCII
705 script, open the file in binary mode and not in text mode with the default
706 (utf8) encoding.
707
Florent Xicluna54467e02010-03-21 12:29:50 +0000708- Issue #8179: Fix macpath.realpath() on a non-existing path.
709

713
Benjamin Peterson689a5582010-03-18 22:29:52 +0000714- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
715 detected.
716
Martin v. Löwis4b003072010-03-16 13:19:21 +0000717- Issue #6716/2: Backslash-replace error output in compilall.
718
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000719- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
720 with Tcl/Tk-8.5.
721
Matthias Klosec33b9022010-03-16 00:36:26 +0000722- Issue #8140: extend compileall to compile single files. Add -i option.

725 the locale.
726
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000727- The internals of the subprocess module on POSIX systems have been replaced
728 by an extension module (_posixsubprocess) so that the fork()+exec() can be
729 done safely without the possibility of deadlock in multithreaded applications.
730
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000731- subprocess.Popen now has restore_signals and start_new_session features.
732 The default of restore_signals=True is a new behavior compared to earlier
733 Python versions. This means that signals such as SIGPIPE are not ignored
734 by default in subprocesses launched by Python (Issue #1652).
735
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000736- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

746 the replacement were all bytes. Patch by Antoine Pitrou.
747
Gerhard Häringf9cee222010-03-05 15:20:03 +0000748- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
749 bugs and allows loading SQLite extensions from shared libraries.

783
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000784- Issue #7597: curses.use_env() can now be called before initscr().
785 Noted by Kan-Ru Chen.

793 bytecode file when it was less then 8 bytes.
794
Mark Dickinson84230a12010-02-18 14:49:50 +0000795- Issue #7633: In the decimal module, Context class methods (with the
796 exception of canonical and is_canonical) now accept instances of int
797 and long wherever a Decimal instance is accepted, and implicitly
798 convert that argument to Decimal. Previously only some arguments
799 were converted.
800
R. David Murray1f449142010-02-11 00:15:05 +0000801- Issue #7835: shelve should no longer produce mysterious warnings during
802 interpreter shutdown.
803
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000804- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
805 in XML processing instructions and comments. These raw characters are
806 allowed by the XML specification, and are necessary when outputting e.g.
807 PHP code in a processing instruction. Patch by Neil Muller.

819 type is specified. Patch by Brian Curtin.
820
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000821- Issue #6939: Fix file I/O objects in the `io` module to keep the original
822 file position when calling `truncate()`. It would previously change the
823 file position to the given argument, which goes against the tradition of
824 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
825
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000826- Issue #7610: Reworked implementation of the internal
827 :class:`zipfile.ZipExtFile` class used to represent files stored inside
828 an archive. The new implementation is significantly faster and can
829 be wrapped in a :class:`io.BufferedReader` object for more speedups.
830 It also solves an issue where interleaved calls to `read()` and
831 `readline()` give wrong results. Patch by Nir Aides.
832
Jesse Noller1f0b6582010-01-27 03:36:01 +0000833- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

835 the worker before that worker is terminated, and a new one created to
836 replace it.
837
Benjamin Petersond6326642010-01-27 02:25:58 +0000838- Issue #7792: Registering non-classes to ABCs raised an obscure error.

995 to execute file paths that refer to source or compiled Python files as well
996 as zipfiles, directories and other valid sys.path entries that contain a
997 __main__.py file. This allows applications that run other Python scripts to

Victor Stinnere125f132010-05-15 21:04:43 +00001017 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001018 recursive locks as fast as regular non-recursive locks (previously,
1019 they were slower by 10x to 15x).

1039 reading from stdin so that existing input does not confuse it and

R. David Murray596da442009-12-14 23:06:11 +00001465- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +00001466 instead of a hardcoded port number in test_rapid_restart.

Victor Stinnere125f132010-05-15 21:04:43 +00001468- Issue #7431: use TESTFN in test_linecache instead of trying to create a
R. David Murrayba311052009-12-04 00:09:14 +00001469 file in the Lib/test directory, which might be read-only for the
1470 user running the tests.

1480 the road because the internally cached encoders and decoders would point
1481 to empty global variables.
1482
Antoine Pitrou941ee882009-11-11 20:59:38 +00001483- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1494 calling methods on the object.
1495
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001496- Issue #7222: Make thread "reaping" more reliable so that reference
1497 leak-chasing test runs give sensible results. The previous method of
1498 reaping threads could return successfully while some Thread objects were
1499 still referenced. This also introduces a new private function:
1500 :func:`_thread._count()`.
1501
R. David Murray27144602009-10-19 15:26:16 +00001502- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1503 longer runs the risk of causing the worker thread to fail.
1504
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001505- Issue #7055: test___all__ now greedily detects all modules which have an
1506 __all__ attribute, rather than using a hardcoded and incomplete list.
1507
R. David Murray0bc11ae2009-10-18 22:18:17 +00001508- Issue #7058: Added save/restore for things like sys.argv and cwd to

1510 and a new section in the summary report at the end.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001785
1786Core and Builtins
1787-----------------
1788
Mark Dickinson865e01a2009-05-07 16:37:01 +00001789- Issue #5914: Add new C API function PyOS_string_to_double, and
1790 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1791
Eric Smith741191f2009-05-06 13:08:15 +00001792- Issue #3382: float.__format__, complex.__format__, and %-formatting
1793 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1794 affects nan -> NAN and inf -> INF.
1795
Mark Hammond5a607a32009-05-06 08:04:54 +00001796- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1797 in all operations, including splitdrive, split, etc. splitunc() now issues
1798 a PendingDeprecation warning.
1799
Eric Smith63376222009-05-05 14:04:18 +00001800- Issue #5920: For float.__format__, change the behavior with the
1801 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1802 to be like 'g' but with at least one decimal point and with a
1803 default precision of 12. Previously, the behavior the same but with
1804 a default precision of 6. This more closely matches str(), and
1805 reduces surprises when adding alignment flags to the empty
1806 presentation type. This also affects the new complex.__format__ in
1807 the same way.
1808
Martin v. Löwis011e8422009-05-05 04:43:17 +00001809- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1810
R. David Murrayb18500d2009-05-04 22:59:07 +00001811- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1812 shadowed by classtype's, even if it was None. property now
1813 inserts the __doc__ into the subclass instance __dict__.
1814
Antoine Pitrou244651a2009-05-04 18:56:13 +00001815- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1816 sequences. Patch by Nick Barnes and Victor Stinner.
1817
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001818- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001819
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001820- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1821 received a new method, detach(). detach() disconnects the underlying stream
1822 from the buffer or text IO and returns it.
1823
Mark Dickinson33841c32009-05-01 15:37:04 +00001824- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1825 floats with absolute value over 1e50. Also remove length
1826 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1827 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001828
Eric Smith741191f2009-05-06 13:08:15 +00001829- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001830 format(complex(1, 2./3), '.5') now produces a sensible result.
1831
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001832- Issue #5864: Fix empty format code formatting for floats so that it
1833 never gives more than the requested number of significant digits.
1834
Eric Smith6dc46f52009-04-27 20:39:49 +00001835- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1836 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1837
Eric Smithcc32a112009-04-26 21:35:14 +00001838- Issue #5835: Deprecate PyOS_ascii_formatd.
1839
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001840- Issue #4971: Fix titlecase for characters that are their own
1841 titlecase, but not their own uppercase.
1842
Benjamin Peterson193152c2009-04-25 01:08:45 +00001843- Issue #5283: Setting __class__ in __del__ caused a segfault.
1844
Mark Dickinsonad476da2009-04-23 19:14:16 +00001845- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1846 z involves nans, infs or negative zeros.
1847
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001848- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001849
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001850- Issue #1869 (and many duplicates): make round(x, n) correctly
1851 rounded for a float x, by using the decimal <-> binary conversions
1852 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1853 consistently agrees with format(x, '.2f').
1854
Benjamin Petersonae937c02009-04-18 20:54:08 +00001855- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1856 some builtin types.
1857
Eric Smith0923d1d2009-04-16 20:16:10 +00001858- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1859
Eric Smith35e84722009-04-16 20:21:28 +00001860- Issue #5515: str.format() type 'n' combined with commas and leading
1861 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001862
1863- Implement PEP 378, Format Specifier for Thousands Separator, for
1864 floats.
1865
Mark Dickinson3370cce2009-04-17 22:40:53 +00001866- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001867 1e11, not 1e12. This avoids printing 13 significant digits in
1868 situations where only 12 of them are correct. Example problem
1869 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1870 long time.)
1871
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001872- Issue #1580: On most platforms, use a 'short' float repr: for a
1873 finite float x, repr(x) now outputs a string based on the shortest
1874 sequence of decimal digits that rounds to x. Previous behaviour was
1875 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001876 Another minor difference is that the new repr switches to
1877 exponential notation at 1e16 instead of the previous 1e17; this
1878 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001879
1880 There's a new sys attribute sys.float_repr_style, which takes
1881 the value 'short' to indicate that we're using short float repr,
1882 and 'legacy' if the short float repr isn't available for one
1883 reason or another.
1884
1885 The float repr change involves incorporating David Gay's 'perfect
1886 rounding' code into the Python core (it's in Python/dtoa.c). As a
1887 secondary consequence, all string-to-float and float-to-string
1888 conversions (including all float formatting operations) will be
1889 correctly rounded on these platforms.
1890
1891 See issue 1580 discussions for details of platforms for which
1892 this change does not apply.
1893
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001894- Issue #5759: float() didn't call __float__ on str subclasses.
1895
Georg Brandlabc38772009-04-12 15:51:51 +00001896- The string.maketrans() function is deprecated; there is a new static method
1897 maketrans() on the bytes and bytearray classes. This removes confusion about
1898 the types string.maketrans() is supposed to work with, and mirrors the
1899 methods available on the str class.
1900
R. David Murraydc6da8a2009-04-09 22:16:43 +00001901- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1902 its clarity and its speed.
1903
Matthias Klose091c7b12009-04-07 13:24:27 +00001904- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1905 to avoid compiler warnings.
1906
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001907- Issue #3739: The unicode-internal encoder now reports the number of characters
1908 consumed like any other encoder (instead of the number of bytes).

2063 the end sys.path, for compatibility with the system install of Python.
2064
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002065- Issue #4688: Add a heuristic so that tuples and dicts containing only
2066 untrackable objects are not tracked by the garbage collector. This can
2067 reduce the size of collections and therefore the garbage collection overhead
2068 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002070- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2071 improve its performance. Long divisions and remainder operations
2072 are now between 50% and 150% faster.
2073
Mark Dickinsonbd792642009-03-18 20:06:12 +00002074- Issue #4258: Make it possible to use base 2**30 instead of base
2075 2**15 for the internal representation of integers, for performance
2076 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2077 --enable-big-digits option to configure, which overrides the
2078 default. Add sys.int_info structseq to provide information about
2079 the internal format.
2080
Mark Dickinson081dfee2009-03-18 14:47:41 +00002081- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2082 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2083 and sizeof(Py_UNICODE) == 2.
2084
Eric Smith8ec90442009-03-14 12:29:34 +00002085- Issue #5237: Allow auto-numbered fields in str.format(). For
2086 example: '{} {}'.format(1, 2) == '1 2'.
2087
Antoine Pitrou652e7072009-03-13 19:25:20 +00002088- Issue #5392: when a very low recursion limit was set, the interpreter would
2089 abort with a fatal error after the recursion limit was hit twice.
2090
Matthias Klose042f1332009-04-04 14:32:42 +00002091- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2137
Lars Gustäbel42e00912009-03-22 20:34:29 +00002138- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2139 forever on incomplete input. That caused tarfile.open() to hang when used
2140 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2141 partial bzip2 compressed data.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002191- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2192 it now forces its argument to double before testing for infinity.
2193
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002194- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2195 returns a non-number type.
2196
Benjamin Peterson87618552009-02-08 15:00:52 +00002197- Issue #5182: Removed memoryview.__str__.

2202 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002203
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002204- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002205 were suppressing all exceptions. These include list() and bytearray().
2206
Mark Dickinson1124e712009-01-28 21:25:58 +00002207- Issue #4707: round(x, n) now returns an integer if x is an integer.
2208 Previously it returned a float.
2209
Antoine Pitroub52ec782009-01-25 16:34:23 +00002210- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2211 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2212 evaluation loop is compiled with a new dispatch mechanism which gives
2213 speedups of up to 20%, depending on the system, on various benchmarks.
2214
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002215- Issue #4874: Most builtin decoders now reject unicode input.

2221
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002222- Issue #4838: When a module is deallocated, free the memory backing the
2223 optional module state data.
2224
Mark Dickinson8055afd2009-01-17 10:04:45 +00002225- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2226 type to (void *).
2227
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002228- Issue #4935: The overflow checking code in the expandtabs() method common
2229 to str, bytes and bytearray could be optimized away by the compiler, letting
2230 the interpreter segfault instead of raising an error.
2231
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002232- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2233 __next__ method.
2234
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002235- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2236 function no longer attempt to call the __long__ slot to convert an object
2237 to an integer. Only the __int__ and __trunc__ slots are examined.
2238
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002239- Issue #4893: Use NT threading on CE.

2242
Antoine Pitrouab868312009-01-10 15:40:25 +00002243- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2244 common cases are optimized thanks to a dedicated fast path and a moderate
2245 amount of loop unrolling.
2246
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002247- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2248 collecting the oldest generation) so that allocating lots of objects without
2249 destroying them does not show quadratic performance. Based on a proposal by
2250 Martin von Löwis at
2251 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2252
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002253- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002254 having been closed (for instance, a read() call could return some
2255 previously buffered data). Patch by Dmitry Vasiliev.
2256
Antoine Pitrou05608432009-01-09 18:53:14 +00002257- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2258 flag to work properly. Furthermore, when specifying -u, the text stdout
2259 and stderr streams have line-by-line buffering enabled (the default being
2260 to buffer arbitrary chunks of data).
2261
Raymond Hettinger35631532009-01-09 03:58:09 +00002262- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2263 instead of ints (reducing its size from 4 to 8 times thereby reducing
2264 Python's overall memory).
2265
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002266- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2267 an existing .py counterpart, override the co_filename attributes of all
2268 code objects if the original filename is obsolete (which can happen if the
2269 file has been renamed, moved, or if it is accessed through different paths).
2270 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2271
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002272- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2273 one byte. Also fixes the meaning of len() so that it returns the number of
2274 items, rather than the size in bytes.
2275
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002276- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2277
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002278- Issue #4747: When the terminal does not use utf-8, executing a script with
2279 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2280
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002281- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002282 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002283
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002284- Issue #3680: Reference cycles created through a dict, set or deque iterator
2285 did not get collected.
2286
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002287- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2288 where the tp_hash and tp_dict slots are both NULL.
2289
Georg Brandlccc47b62008-12-28 11:44:14 +00002290- Issue #4759: None is now allowed as the first argument of
2291 bytearray.translate(). It was always allowed for bytes.translate().
2292
Skip Montanaro80072cb2008-12-23 03:51:14 +00002293- Added test case to ensure attempts to read from a file opened for writing
2294 fail.
2295
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002296- Issue #3106: Speedup some comparisons (str/str and int/int).

2299 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2300
Antoine Pitrou621601a2008-12-17 23:18:19 +00002301- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2302 print elapsed times, not only when some objects are uncollectable /
2303 unreachable. Original patch by Neil Schemenauer.
2304
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002305- Issue #3439: Add a bit_length method to int.
2306
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002307- Issue #2173: When getting device encoding, check that return value of
2308 nl_langinfo is not the empty string. This was causing silent build
2309 failures on OS X.
2310
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002311- Issue #4597: Fixed several opcodes that weren't always propagating
2312 exceptions.
2313
2314- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002315 context manager returns a value that cannot be converted to a bool.
2316
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002317- Issue #4445: Replace "sizeof(PyBytesObject)" with
2318 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2319 bytes instances. On a typical machine this saves 3 bytes of memory
2320 (on average) per allocation of a bytes instance.
2321
Christian Heimesa872de52008-12-05 08:26:55 +00002322- Issue #4533: File read operation was dreadfully slow due to a slowly
2323 growing read buffer. Fixed by using the same growth rate algorithm as
2324 Python 2.x.
2325
Antoine Pitrou5504e892008-12-06 21:27:53 +00002326- Issue #4509: Various issues surrounding resize of bytearray objects to
2327 which there are buffer exports (e.g. memoryview instances).
2328
Georg Brandlf9734072008-12-07 15:30:06 +00002329- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2330 method on file objects with closefd=False. The file descriptor is still
2331 kept open but the file object behaves like a closed file. The ``FileIO``
2332 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002333
Antoine Pitroubc420402008-12-07 20:14:49 +00002334- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2335 larger than 1.

2340
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002341- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2342 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2343 step. This avoids problems with counting UTF-8 bytes that ignores the effect

Antoine Pitrou31f30b12009-01-02 17:34:35 +00002925- Issue #4738: Each zlib object now has a separate lock, allowing to compress
2926 or decompress several streams at once on multi-CPU systems. Also, the GIL
2927 is now released when computing the CRC of a large buffer. Patch by ebfe.

Antoine Pitrou88909542009-06-29 13:54:42 +00002946- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2947 regression tests in parallel, shortening the total runtime.
2948
Guilherme Polo2a998fa2009-06-21 17:40:07 +00002949- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2950 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2951 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2952 skip the tests if DISPLAY is defined but can't be used.
2953
R. David Murraya21e4ca2009-03-31 23:16:50 +00002954- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002955 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002956 from test support, which does the conversion.
2957
Guilherme Polo9de29af2009-01-28 20:40:48 +00002958- Issue #5083: New 'gui' resource for regrtest.
