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

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

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

Antoine Pitrouf978fac2010-05-21 17:25:34 +0000336- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
337 embedders of the interpreter to set sys.argv without also modifying
338 sys.path. This helps fix `CVE-2008-5983
339 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
340
Benjamin Petersonfb886362010-04-24 18:21:17 +0000341- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are

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 +0000486- Issue #8567: Fix precedence of signals in Decimal module: when a
487 Decimal operation raises multiple signals and more than one of those
488 signals is trapped, the specification determines the order in which
489 the signals should be handled. In many cases this order wasn't
490 being followed, leading to the wrong Python exception being raised.

531 would be turned into a non-blocking SSL socket).
532
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000533- Issue #5103: SSL handshake would ignore the socket timeout and block

Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000606- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
607 module now takes an optional timeout argument in seconds. Timeout support
608 relies on the system threading library, so as to avoid a semi-busy wait
609 loop.
610
Victor Stinner485fb562010-04-13 11:07:24 +0000611- Issue #8383: pickle and pickletools use surrogatepass error handler when
612 encoding unicode as utf8 to support lone surrogates and stay compatible with
613 Python 2.x and 3.0
614
R. David Murrayb2416e52010-04-12 16:58:02 +0000615- Issue #7585: difflib context and unified diffs now place a tab between
616 filename and date, conforming to the 'standards' they were originally
617 designed to follow. This improves compatibility with patch tools.
618
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000619- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
620 character sets will now consistently use a Content-Transfer-Encoding of
621 7bit rather than sometimes being marked as 8bit.
622
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000623- Issue #8375: test_distutils now checks if the temporary directory are still
624 present before it cleans them.
625
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000626- Issue #8374: Update the internal alias table in the :mod:`locale` module
627 to cover recent locale changes and additions.
628
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000629- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
630 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
631 and `ssl.OPENSSL_VERSION_NUMBER`.
632
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000633- Add functools.total_ordering() and functools.cmp_to_key().
634
Mark Dickinson089b00c2010-04-03 15:51:03 +0000635- Issue #8257: The Decimal construct now accepts a float instance
636 directly, converting that float to a Decimal of equal value:
637
638 >>> Decimal(1.1)
639 Decimal('1.100000000000000088817841970012523233890533447265625')
640
Mark Dickinson98127c32010-04-03 11:18:52 +0000641- Issue #8294: The Fraction constructor now accepts Decimal and float
642 instances directly.
643
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000644- Issue #7279: Comparisons involving a Decimal signaling NaN now
645 signal InvalidOperation instead of returning False. (Comparisons
646 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
647 are now hashable; Decimal signaling NaNs remain unhashable.
648
649- Issue #2531: Comparison operations between floats and Decimal
650 instances now return a result based on the numeric values of the
651 operands; previously they returned an arbitrary result based on
652 the relative ordering of id(float) and id(Decimal).
653
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000654- Added a subtract() method to collections.Counter().
655
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000656- Issue #8233: When run as a script, py_compile.py optionally takes a single
657 argument `-` which tells it to read files to compile from stdin. Each line
658 is read on demand and the named file is compiled immediately. (Original
659 patch by Piotr Ożarowski).
660
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000661- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
662 form feed (0x0C) are now considered linebreaks, as specified in Unicode
663 Standard Annex #14. See issue #7643.
664 http://www.unicode.org/reports/tr14/
665
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000666- Comparisons using one of <, <=, >, >= between a complex instance and
667 a Fractions instance now raise TypeError instead of returning
668 True/False. This makes Fraction <=> complex comparisons consistent with
669 int <=> complex, float <=> complex, and complex <=> complex comparisons.
670
Antoine Pitrou39b35432010-03-23 00:25:54 +0000671- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
672 some methods (such as oss_mixer_device.fileno()) were not available.
673 Initial patch by Bertrand Janin.
674
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000675- Issue #8205: Remove the "Modules" directory from sys.path when Python is
676 running from the build directory (POSIX only).
677
Antoine Pitrou910bd512010-03-22 20:11:09 +0000678- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
679 didn't support chflags() (for example ZFS under FreeBSD). The error is
680 now silenced.
681
R. David Murrayca2edce2010-03-22 17:48:48 +0000682- Issue #7860: platform.uname now reports the correct 'machine' type
683 when Python is running in WOW64 mode on 64 bit Windows.
684
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000685- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
686 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
687 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000688
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000689- Issue #4282: Fix the main function of the profile module for a non-ASCII
690 script, open the file in binary mode and not in text mode with the default
691 (utf8) encoding.
692
Florent Xicluna54467e02010-03-21 12:29:50 +0000693- Issue #8179: Fix macpath.realpath() on a non-existing path.
694

698
Benjamin Peterson689a5582010-03-18 22:29:52 +0000699- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
700 detected.
701
Martin v. Löwis4b003072010-03-16 13:19:21 +0000702- Issue #6716/2: Backslash-replace error output in compilall.
703
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000704- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
705 with Tcl/Tk-8.5.
706
Matthias Klosec33b9022010-03-16 00:36:26 +0000707- Issue #8140: extend compileall to compile single files. Add -i option.

710 the locale.
711
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000712- The internals of the subprocess module on POSIX systems have been replaced
713 by an extension module (_posixsubprocess) so that the fork()+exec() can be
714 done safely without the possibility of deadlock in multithreaded applications.
715
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000716- subprocess.Popen now has restore_signals and start_new_session features.
717 The default of restore_signals=True is a new behavior compared to earlier
718 Python versions. This means that signals such as SIGPIPE are not ignored
719 by default in subprocesses launched by Python (Issue #1652).
720
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000721- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

731 the replacement were all bytes. Patch by Antoine Pitrou.
732
Gerhard Häringf9cee222010-03-05 15:20:03 +0000733- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
734 bugs and allows loading SQLite extensions from shared libraries.

768
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000769- Issue #7597: curses.use_env() can now be called before initscr().
770 Noted by Kan-Ru Chen.
771

778 bytecode file when it was less then 8 bytes.
779
Mark Dickinson84230a12010-02-18 14:49:50 +0000780- Issue #7633: In the decimal module, Context class methods (with the
781 exception of canonical and is_canonical) now accept instances of int
782 and long wherever a Decimal instance is accepted, and implicitly
783 convert that argument to Decimal. Previously only some arguments
784 were converted.
785
R. David Murray1f449142010-02-11 00:15:05 +0000786- Issue #7835: shelve should no longer produce mysterious warnings during
787 interpreter shutdown.
788
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000789- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
790 in XML processing instructions and comments. These raw characters are
791 allowed by the XML specification, and are necessary when outputting e.g.
792 PHP code in a processing instruction. Patch by Neil Muller.

804 type is specified. Patch by Brian Curtin.
805
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000806- Issue #6939: Fix file I/O objects in the `io` module to keep the original
807 file position when calling `truncate()`. It would previously change the
808 file position to the given argument, which goes against the tradition of
809 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
810
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000811- Issue #7610: Reworked implementation of the internal
812 :class:`zipfile.ZipExtFile` class used to represent files stored inside
813 an archive. The new implementation is significantly faster and can
814 be wrapped in a :class:`io.BufferedReader` object for more speedups.
815 It also solves an issue where interleaved calls to `read()` and
816 `readline()` give wrong results. Patch by Nir Aides.
817
Jesse Noller1f0b6582010-01-27 03:36:01 +0000818- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

820 the worker before that worker is terminated, and a new one created to
821 replace it.
822

932 ownership when the group is not forced, because the group may be different
933 from the user's group and inherit from its container when the test is run.
934

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000979- Issue #6816: runpy now provides a run_path function that allows Python code
980 to execute file paths that refer to source or compiled Python files as well
981 as zipfiles, directories and other valid sys.path entries that contain a
982 __main__.py file. This allows applications that run other Python scripts to
983 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001002 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001003 recursive locks as fast as regular non-recursive locks (previously,
1004 they were slower by 10x to 15x).

1024 reading from stdin so that existing input does not confuse it and
1025 lead to incorrect entry or an IOError. It also properly flushes it
1026 afterwards to avoid the terminal echoing the input afterwards on
1027 OSes such as Solaris.

1214 algorithm with an improved 'binary-split' algorithm that uses fewer
1215 multiplications and allows many of the multiplications to be

1477 leak-chasing test runs give sensible results. The previous method of
1478 reaping threads could return successfully while some Thread objects were
1479 still referenced. This also introduces a new private function:

1766Core and Builtins
1767-----------------
1768
Mark Dickinson865e01a2009-05-07 16:37:01 +00001769- Issue #5914: Add new C API function PyOS_string_to_double, and
1770 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1771
Eric Smith741191f2009-05-06 13:08:15 +00001772- Issue #3382: float.__format__, complex.__format__, and %-formatting
1773 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1774 affects nan -> NAN and inf -> INF.
1775
Mark Hammond5a607a32009-05-06 08:04:54 +00001776- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1777 in all operations, including splitdrive, split, etc. splitunc() now issues
1778 a PendingDeprecation warning.
1779
Eric Smith63376222009-05-05 14:04:18 +00001780- Issue #5920: For float.__format__, change the behavior with the
1781 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1782 to be like 'g' but with at least one decimal point and with a
1783 default precision of 12. Previously, the behavior the same but with
1784 a default precision of 6. This more closely matches str(), and
1785 reduces surprises when adding alignment flags to the empty
1786 presentation type. This also affects the new complex.__format__ in
1787 the same way.
1788
Martin v. Löwis011e8422009-05-05 04:43:17 +00001789- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1790
R. David Murrayb18500d2009-05-04 22:59:07 +00001791- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1792 shadowed by classtype's, even if it was None. property now
1793 inserts the __doc__ into the subclass instance __dict__.
1794
Antoine Pitrou244651a2009-05-04 18:56:13 +00001795- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1796 sequences. Patch by Nick Barnes and Victor Stinner.
1797
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001798- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001799
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001800- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1801 received a new method, detach(). detach() disconnects the underlying stream
1802 from the buffer or text IO and returns it.
1803
Mark Dickinson33841c32009-05-01 15:37:04 +00001804- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1805 floats with absolute value over 1e50. Also remove length
1806 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1807 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001808
Eric Smith741191f2009-05-06 13:08:15 +00001809- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001810 format(complex(1, 2./3), '.5') now produces a sensible result.
1811
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001812- Issue #5864: Fix empty format code formatting for floats so that it
1813 never gives more than the requested number of significant digits.
1814
Eric Smith6dc46f52009-04-27 20:39:49 +00001815- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1816 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1817
Eric Smithcc32a112009-04-26 21:35:14 +00001818- Issue #5835: Deprecate PyOS_ascii_formatd.
1819
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001820- Issue #4971: Fix titlecase for characters that are their own
1821 titlecase, but not their own uppercase.
1822
Benjamin Peterson193152c2009-04-25 01:08:45 +00001823- Issue #5283: Setting __class__ in __del__ caused a segfault.
1824
Mark Dickinsonad476da2009-04-23 19:14:16 +00001825- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1826 z involves nans, infs or negative zeros.
1827
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001828- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001829
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001830- Issue #1869 (and many duplicates): make round(x, n) correctly
1831 rounded for a float x, by using the decimal <-> binary conversions
1832 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1833 consistently agrees with format(x, '.2f').
1834
Benjamin Petersonae937c02009-04-18 20:54:08 +00001835- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1836 some builtin types.
1837
Eric Smith0923d1d2009-04-16 20:16:10 +00001838- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1839
Eric Smith35e84722009-04-16 20:21:28 +00001840- Issue #5515: str.format() type 'n' combined with commas and leading
1841 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001842
1843- Implement PEP 378, Format Specifier for Thousands Separator, for
1844 floats.
1845
Mark Dickinson3370cce2009-04-17 22:40:53 +00001846- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001847 1e11, not 1e12. This avoids printing 13 significant digits in
1848 situations where only 12 of them are correct. Example problem
1849 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1850 long time.)
1851
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001852- Issue #1580: On most platforms, use a 'short' float repr: for a
1853 finite float x, repr(x) now outputs a string based on the shortest
1854 sequence of decimal digits that rounds to x. Previous behaviour was
1855 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001856 Another minor difference is that the new repr switches to
1857 exponential notation at 1e16 instead of the previous 1e17; this
1858 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001859
1860 There's a new sys attribute sys.float_repr_style, which takes
1861 the value 'short' to indicate that we're using short float repr,
1862 and 'legacy' if the short float repr isn't available for one
1863 reason or another.
1864
1865 The float repr change involves incorporating David Gay's 'perfect
1866 rounding' code into the Python core (it's in Python/dtoa.c). As a
1867 secondary consequence, all string-to-float and float-to-string
1868 conversions (including all float formatting operations) will be
1869 correctly rounded on these platforms.
1870
1871 See issue 1580 discussions for details of platforms for which
1872 this change does not apply.
1873
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001874- Issue #5759: float() didn't call __float__ on str subclasses.
1875
Georg Brandlabc38772009-04-12 15:51:51 +00001876- The string.maketrans() function is deprecated; there is a new static method
1877 maketrans() on the bytes and bytearray classes. This removes confusion about
1878 the types string.maketrans() is supposed to work with, and mirrors the
1879 methods available on the str class.
1880
R. David Murraydc6da8a2009-04-09 22:16:43 +00001881- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
1882 its clarity and its speed.
1883
Matthias Klose091c7b12009-04-07 13:24:27 +00001884- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1885 to avoid compiler warnings.
1886
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001887- Issue #3739: The unicode-internal encoder now reports the number of characters
1888 consumed like any other encoder (instead of the number of bytes).

1903
Vinay Sajipaffbd872009-06-11 10:11:47 +00001904- Issue #5940: distutils.command.build_clib.check_library_list was not doing

1967 results in a handle_expt_event call, not handle_read_event, and POLLERR
1968 and POLLNVAL now call handle_close, not handle_expt_event. Also,
1969 dispatcher now has an 'ignore_log_types' attribute for suppressing
1970 log messages, which is set to 'warning' by default.
1971
Matthias Klosea3d29e82009-04-07 13:13:10 +00001972- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for

2044
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002045- Issue #4688: Add a heuristic so that tuples and dicts containing only
2046 untrackable objects are not tracked by the garbage collector. This can
2047 reduce the size of collections and therefore the garbage collection overhead
2048 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002171- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2172 it now forces its argument to double before testing for infinity.
2173
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002174- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002183
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002184- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002185 were suppressing all exceptions. These include list() and bytearray().
2186
Mark Dickinson1124e712009-01-28 21:25:58 +00002187- Issue #4707: round(x, n) now returns an integer if x is an integer.
2188 Previously it returned a float.
2189
Antoine Pitroub52ec782009-01-25 16:34:23 +00002190- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2191 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2192 evaluation loop is compiled with a new dispatch mechanism which gives
2193 speedups of up to 20%, depending on the system, on various benchmarks.
2194
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002195- Issue #4874: Most builtin decoders now reject unicode input.

2201
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002202- Issue #4838: When a module is deallocated, free the memory backing the
2203 optional module state data.
2204
Mark Dickinson8055afd2009-01-17 10:04:45 +00002205- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2206 type to (void *).
2207
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002208- Issue #4935: The overflow checking code in the expandtabs() method common
2209 to str, bytes and bytearray could be optimized away by the compiler, letting
2210 the interpreter segfault instead of raising an error.
2211
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002212- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2213 __next__ method.
2214
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002215- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2216 function no longer attempt to call the __long__ slot to convert an object
2217 to an integer. Only the __int__ and __trunc__ slots are examined.
2218
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002219- Issue #4893: Use NT threading on CE.
2220

2222
Antoine Pitrouab868312009-01-10 15:40:25 +00002223- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2224 common cases are optimized thanks to a dedicated fast path and a moderate
2225 amount of loop unrolling.
2226
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002227- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2228 collecting the oldest generation) so that allocating lots of objects without
2229 destroying them does not show quadratic performance. Based on a proposal by
2230 Martin von Löwis at
2231 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2232
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002233- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002234 having been closed (for instance, a read() call could return some
2235 previously buffered data). Patch by Dmitry Vasiliev.
2236
Antoine Pitrou05608432009-01-09 18:53:14 +00002237- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2238 flag to work properly. Furthermore, when specifying -u, the text stdout
2239 and stderr streams have line-by-line buffering enabled (the default being
2240 to buffer arbitrary chunks of data).
2241
Raymond Hettinger35631532009-01-09 03:58:09 +00002242- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2243 instead of ints (reducing its size from 4 to 8 times thereby reducing
2244 Python's overall memory).
2245
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002246- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2247 an existing .py counterpart, override the co_filename attributes of all
2248 code objects if the original filename is obsolete (which can happen if the
2249 file has been renamed, moved, or if it is accessed through different paths).
2250 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2251
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002252- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2253 one byte. Also fixes the meaning of len() so that it returns the number of
2254 items, rather than the size in bytes.
2255
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002256- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2257
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002258- Issue #4747: When the terminal does not use utf-8, executing a script with
2259 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2260
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002261- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002262 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002263
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002264- Issue #3680: Reference cycles created through a dict, set or deque iterator
2265 did not get collected.
2266
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002267- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2268 where the tp_hash and tp_dict slots are both NULL.
2269
Georg Brandlccc47b62008-12-28 11:44:14 +00002270- Issue #4759: None is now allowed as the first argument of
2271 bytearray.translate(). It was always allowed for bytes.translate().
2272
Skip Montanaro80072cb2008-12-23 03:51:14 +00002273- Added test case to ensure attempts to read from a file opened for writing
2274 fail.

2283 unreachable. Original patch by Neil Schemenauer.
2284

2286
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002287- Issue #2173: When getting device encoding, check that return value of
2288 nl_langinfo is not the empty string. This was causing silent build
2289 failures on OS X.
2290
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002291- Issue #4597: Fixed several opcodes that weren't always propagating
2292 exceptions.
2293
2294- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002295 context manager returns a value that cannot be converted to a bool.
2296
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002297- Issue #4445: Replace "sizeof(PyBytesObject)" with
2298 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2299 bytes instances. On a typical machine this saves 3 bytes of memory
2300 (on average) per allocation of a bytes instance.
2301
Christian Heimesa872de52008-12-05 08:26:55 +00002302- Issue #4533: File read operation was dreadfully slow due to a slowly
2303 growing read buffer. Fixed by using the same growth rate algorithm as
2304 Python 2.x.
2305
Antoine Pitrou5504e892008-12-06 21:27:53 +00002306- Issue #4509: Various issues surrounding resize of bytearray objects to
2307 which there are buffer exports (e.g. memoryview instances).
2308
Georg Brandlf9734072008-12-07 15:30:06 +00002309- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2310 method on file objects with closefd=False. The file descriptor is still
2311 kept open but the file object behaves like a closed file. The ``FileIO``
2312 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002314- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2322 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2323 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2324 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00002926- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
2927 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00002929- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
2930 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2931 the same behaviour as test_ttkguionly (and now also test_tk) which is to
2932 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00002934- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002935 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002936 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00002938- Issue #5083: New 'gui' resource for regrtest.
