12Core and Builtins
13-----------------
14
Victor Stinner554f3f02010-06-16 23:33:54 +000015- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
16 mode raises unicode errors. The encoder only supports "strict" and "replace"
17 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000018 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000019
Victor Stinner06e49dd2010-06-13 18:21:50 +000020- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
21 formats if the string contains a null byte/character. Write unit tests for
22 string formats.
23
Nick Coghlan5e76e942010-06-12 13:42:46 +000024- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
25 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
26 location of the raised exception.
27
Victor Stinner313a1202010-06-11 23:56:51 +000028- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
29 filenames and enable os.fsencode().
30
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000031- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
32 the interpreter with characters outside the Basic Multilingual Plane
33 (higher than 0x10000).
34
Mark Dickinsonc7301312010-06-10 16:05:10 +000035- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
36 raise TypeError instead of giving a DeprecationWarning when a float
37 is parsed using the 'L' code (for long long). (All other integer
38 codes already raise TypeError in this case.)
39
Victor Stinner600d3be2010-06-10 12:00:55 +000040- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
41 enable shortcuts for upper case encoding name. Add also a shortcut for
42 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
43
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000044- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
45 doesn't support "char buffer" anymore in Python3.
46
47- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
48 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
49 like bytearray.
50
Victor Stinner33109a12010-05-28 21:55:10 +000051- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
52 used anymore and it was never documented.
53
Benjamin Peterson95304522010-06-08 14:57:22 +000054- In the str.format(), raise a ValueError when indexes to arguments are too
55 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000056
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000057- Issue #2844: Make int('42', n) consistently raise ValueError for
58 invalid integers n (including n = -909).
59
Mark Dickinsondc787d22010-05-23 13:33:13 +000060- Issue #8188: Introduce a new scheme for computing hashes of numbers
61 (instances of int, float, complex, decimal.Decimal and
62 fractions.Fraction) that makes it easy to maintain the invariant
63 that hash(x) == hash(y) whenever x and y have equal value.
64
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000065- Issue #8748: Fix two issues with comparisons between complex and integer
66 objects. (1) The comparison could incorrectly return True in some cases
67 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
68 (2) The comparison raised an OverflowError for large integers, leading
69 to unpredictable exceptions when combining integers and complex objects
70 in sets or dicts.
71
Victor Stinner7d79b8b2010-05-19 20:40:50 +000072- Issue #8766: Initialize _warnings module before importing the first module.
73 Fix a crash if an empty directory called "encodings" exists in sys.path.
74
Victor Stinner9ca9c252010-05-19 16:53:30 +000075- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
76 encoding and surrogateespace error handler instead of the locale encoding to
77 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
78
Victor Stinner372ac5e2010-05-17 01:26:01 +000079- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
80 (instead of strict) error handler to escape surrogates
81
Victor Stinnerae6265f2010-05-15 16:27:27 +000082- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
83 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000084 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
85 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000086
Victor Stinner59e62db2010-05-15 13:14:32 +000087- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
88 error handler, not only the default error handler (strict)
89
Victor Stinnerb744ba12010-05-15 12:27:16 +000090- Issue #8610: Load file system codec at startup, and display a fatal error on
91 failure. Set the file system encoding to utf-8 (instead of None) if getting
92 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
93
Victor Stinner0964ee12010-04-30 16:48:45 +000094- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
95 PyUnicode_FromString() to support surrogates in the filename and use the
96 right encoding
97
Georg Brandl8569e582010-05-19 20:57:08 +000098- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
99
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000100- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
101
Benjamin Petersonfb886362010-04-24 18:21:17 +0000102- Issue #8419: Prevent the dict constructor from accepting non-string keyword
103 arguments.
104
Victor Stinner14284c22010-04-23 12:02:30 +0000105- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
106 indirectly Python signal handlers anymore because mywrite() ignores
107 exceptions (KeyboardInterrupt)
108
Victor Stinner31be90b2010-04-22 19:38:16 +0000109- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
110 unicode string (eg. backslashreplace)
111
Victor Stinnerdcb24032010-04-22 12:08:36 +0000112- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
113 you have to convert your bytearray filenames to bytes
114
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000115- Issue #7332: Remove the 16KB stack-based buffer in
116 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
117 benefit compared to the dynamic memory allocation fallback. Patch by
118 Charles-François Natali.
119
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000120- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
121 passed to bytes or bytearray.
122
Philip Jenvey0805ca32010-04-07 04:04:10 +0000123- Issue #7301: Add environment variable $PYTHONWARNINGS.
124
Benjamin Petersond856ab62010-04-06 21:55:16 +0000125- Issue #8329: Don't return the same lists from select.select when no fds are
126 changed.
127
Mark Dickinson3318d292010-04-06 16:53:17 +0000128- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
129 on 64-bit machines. The shift count for either left or right shift is
130 permitted to be up to sys.maxsize.
131
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000132- Ensure that tokenization of identifiers is not affected by locale.

139 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000140
Victor Stinner120c2122010-03-25 00:30:28 +0000141- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
142 is unknown
143
Victor Stinner808fc0a2010-03-22 12:50:40 +0000144- Issue #1583863: An str subclass can now override the __str__ method
145
Mark Dickinsond59b4162010-03-13 11:34:40 +0000146- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
147 PyMemberDefs could produce an internal error; raise TypeError instead.
148
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000149- Issue #7845: Rich comparison methods on the complex type now return
150 NotImplemented rather than raising a TypeError when comparing with an
151 incompatible type; this allows user-defined classes to implement their own
152 comparisons with complex.
153
Victor Stinner52f6dd72010-03-12 14:45:56 +0000154- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
155 (SIGINT). If an error occurs while importing the site module, the error is
156 printed and Python exits. Initialize the GIL before importing the site
157 module.
158
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000159- Issue #7173: Generator finalization could invalidate sys.exc_info().

162 a fatal error in low memory condition.
163
Victor Stinner6aa278e2010-03-03 00:18:49 +0000164- Issue #7820: The parser tokenizer restores all bytes in the right if
165 the BOM check fails.
166

168
Larry Hastings1373a072010-02-24 22:49:58 +0000169- Issue #5939: Add additional runtime checking to ensure a valid capsule
170 in Modules/_ctypes/callproc.c.
171
Eric Smith0facd772010-02-24 15:42:29 +0000172- Issue #7309: Fix unchecked attribute access when converting
173 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
174 strings.
175

183 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
184 and PyOS_string_to_double instead. See issue #5835 for the original
185 deprecations.
186
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000187- Issue #7385: Fix a crash in `MemoryView_FromObject` when
188 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
189
Mark Dickinsonbc099642010-01-29 17:27:24 +0000190- Issue #7788: Fix an interpreter crash produced by deleting a list
191 slice with very large step value.
192
Eric Smithf7bb5782010-01-27 00:44:57 +0000193- Issue #7766: Change sys.getwindowsversion() return value to a named
194 tuple and add the additional members returned in an OSVERSIONINFOEX
195 structure. The new members are service_pack_major, service_pack_minor,
196 suite_mask, and product_type.
197
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000198- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
199 could crash in many places because of the PyByteArray_AS_STRING() macro
200 returning NULL. The macro now returns a statically allocated empty
201 string instead.
202
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000203- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
204 where the right hand operand is a set of constants, by turning the set into
205 a frozenset and pre-building it as a constant. The comparison operation
206 is made against the constant instead of building a new set each time it is
207 executed (a similar optimization already existed which turned a list of
208 constants into a pre-built tuple). Patch and additional tests by Dave
209 Malcolm.
210
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000211- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
212 methods of bytes, bytearray and unicode objects by using a common
213 implementation based on stringlib's fast search. Patch by Florent Xicluna.
214

216 alpha 2, including: (1) a serious 'wrong output' bug that could
217 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
218 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000219 strings corresponding to subnormal values, (3) a memory leak for
220 some values large enough to cause overflow, and (4) a number of
221 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000222
Benjamin Petersonaea44282010-01-04 01:10:28 +0000223- The __complex__ method is now looked up on the class of instances to make it
224 consistent with other special methods.
225

227 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
228
Benjamin Petersond12362a2009-12-30 19:44:54 +0000229- Issue #7604: Deleting an unset slotted attribute did not raise an
230 AttributeError.
231
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000232- Issue #7534: Fix handling of IEEE specials (infinities, nans,
233 negative zero) in ** operator. The behaviour now conforms to that
234 described in C99 Annex F.
235
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000236- Issue #1811: improve accuracy and cross-platform consistency for
237 true division of integers: the result of a/b is now correctly
238 rounded for ints a and b (at least on IEEE 754 platforms), and in
239 particular does not depend on the internal representation of an int.
240
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000241- Issue #6834: replace the implementation for the 'python' and 'pythonw'
242 executables on OSX.
243
244 These executables now work properly with the arch(1) command:
245 ``arch -ppc python`` will start a universal binary version of python
246 in PPC mode (unlike previous releases).
247
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000248- Issue #7466: segmentation fault when the garbage collector is called
249 in the middle of populating a tuple. Patch by Florent Xicluna.

256
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000257- Issue #7085: Fix crash when importing some extensions in a thread
258 on MacOSX 10.6.

263 implement the relevant rich comparison methods.
264
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000265- Issue #7298: fixes for range and reversed(range(...)). Iteration
266 over range(a, b, c) incorrectly gave an empty iterator when a, b and
267 c fit in C long but the length of the range did not. Also fix
268 several cases where reversed(range(a, b, c)) gave wrong results, and
269 fix a refleak for reversed(range(a, b, c)) with large arguments.
270
Raymond Hettingerfc438512009-11-01 20:55:33 +0000271- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Mark Dickinson08ade6f2010-06-11 10:44:52 +0000455 now permitted, returning a result based on the exact numerical
456 values of the operands. This builds on issue #2531, which allowed
457 Decimal-to-float comparisons; all comparisons involving numeric
458 types (bool, int, float, complex, Decimal, Fraction) should now

Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000609 webbrowser.get("safari").
610
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000611- Issue #8464: tarfile no longer creates files with execute permissions set
612 when mode="w|" is used.
613
Antoine Pitroubf043492010-04-29 10:11:46 +0000614- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
615 of the Linux kernel. Patch by Yaniv Aknin.
616

618
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000619- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
620 It should correctly return an empty response now.
621
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000622- Issue #8546: Reject None given as the buffering argument to _pyio.open.
623
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000624- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
625 Sridhar Ratnakumar.
626
R. David Murrayad78d152010-04-27 02:45:53 +0000627- Issue #6656: fix locale.format_string to handle escaped percents
628 and mappings.
629
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000630- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
631 where the method could block indefinitely if called just before the
632 event loop started running. This also fixes the occasional freezes
633 witnessed in test_httpservers.
634
Antoine Pitrou40f08742010-04-24 22:04:40 +0000635- Issue #8524: When creating an SSL socket, the timeout value of the
636 original socket wasn't retained (instead, a socket with a positive timeout
637 would be turned into a non-blocking SSL socket).
638
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000639- Issue #5103: SSL handshake would ignore the socket timeout and block
640 indefinitely if the other end didn't respond.
641
642- The do_handshake() method of SSL objects now adjusts the blocking mode of
643 the SSL structure if necessary (as other methods already do).
644
Victor Stinner13bb71c2010-04-23 21:41:56 +0000645- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
646 and bytes strings for environment keys and values
647
Victor Stinner4d078042010-04-23 19:28:32 +0000648- Issue #8467: Pure Python implementation of subprocess encodes the error

653
Sean Reifscheider13daf122010-04-23 09:29:52 +0000654- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
655 the string "python" as the *ident*. openlog() arguments are all optional
656 and keywords.
657
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000658- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
659 a non-infinite timeout. Also make that method friendlier with applications
660 wanting to continue using the socket in clear-text mode, by disabling
661 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
662
Antoine Pitrou7062db82010-04-22 13:30:10 +0000663- Issue #8496: make mailcap.lookup() always return a list, rather than an
664 iterator. Patch by Gregory Nofi.
665
Victor Stinner35466c52010-04-22 11:23:23 +0000666- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
667 collation name contains a surrogate character.
668
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000669- Issue #8484: Load all ciphers and digest algorithms when initializing
670 the _ssl extension, such that verification of some SSL certificates
671 doesn't fail because of an "unknown algorithm".
672
Tarek Ziadéfb437512010-04-20 08:57:33 +0000673- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
674
Victor Stinnere125f132010-05-15 21:04:43 +0000675- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000676 shutil.copytree.
677
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000678- Issue #4814: timeout parameter is now applied also for connections resulting
679 from PORT/EPRT commands.
680
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000681- Issue #8463: added missing reference to bztar in shutil's documentation.
682
Ronald Oussoren84151202010-04-18 20:46:11 +0000683- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
684 (as long as the user didn't specify 'automatic proxy configuration').
685
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000686- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
687 code as stated in RFC-959 at chapter 5.4.
688
Victor Stinner738446f02010-04-18 00:00:44 +0000689- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
690 surrogates.
691
Antoine Pitrou0454af92010-04-17 23:51:58 +0000692- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000693 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000694
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000695- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
696 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
697
Victor Stinner0e59cc32010-04-16 23:49:32 +0000698- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
699 the current working directory.
700

711
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000712- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
713 module now takes an optional timeout argument in seconds. Timeout support
714 relies on the system threading library, so as to avoid a semi-busy wait
715 loop.
716
Victor Stinner485fb562010-04-13 11:07:24 +0000717- Issue #8383: pickle and pickletools use surrogatepass error handler when
718 encoding unicode as utf8 to support lone surrogates and stay compatible with
719 Python 2.x and 3.0
720
R. David Murrayb2416e52010-04-12 16:58:02 +0000721- Issue #7585: difflib context and unified diffs now place a tab between
722 filename and date, conforming to the 'standards' they were originally
723 designed to follow. This improves compatibility with patch tools.
724
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000725- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
726 character sets will now consistently use a Content-Transfer-Encoding of
727 7bit rather than sometimes being marked as 8bit.
728
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000729- Issue #8375: test_distutils now checks if the temporary directory are still
730 present before it cleans them.
731
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000732- Issue #8374: Update the internal alias table in the :mod:`locale` module
733 to cover recent locale changes and additions.
734
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000735- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
736 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
737 and `ssl.OPENSSL_VERSION_NUMBER`.
738
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000739- Add functools.total_ordering() and functools.cmp_to_key().
740
Mark Dickinson089b00c2010-04-03 15:51:03 +0000741- Issue #8257: The Decimal construct now accepts a float instance
742 directly, converting that float to a Decimal of equal value:
743
744 >>> Decimal(1.1)
745 Decimal('1.100000000000000088817841970012523233890533447265625')
746
Mark Dickinson98127c32010-04-03 11:18:52 +0000747- Issue #8294: The Fraction constructor now accepts Decimal and float
748 instances directly.
749
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000750- Issue #7279: Comparisons involving a Decimal signaling NaN now
751 signal InvalidOperation instead of returning False. (Comparisons
752 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
753 are now hashable; Decimal signaling NaNs remain unhashable.
754
755- Issue #2531: Comparison operations between floats and Decimal
756 instances now return a result based on the numeric values of the
757 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000758 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000759 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000760
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000761- Added a subtract() method to collections.Counter().
762
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000763- Issue #8233: When run as a script, py_compile.py optionally takes a single
764 argument `-` which tells it to read files to compile from stdin. Each line
765 is read on demand and the named file is compiled immediately. (Original
766 patch by Piotr Ożarowski).
767
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000768- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
769 form feed (0x0C) are now considered linebreaks, as specified in Unicode
770 Standard Annex #14. See issue #7643.
771 http://www.unicode.org/reports/tr14/
772
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000773- Comparisons using one of <, <=, >, >= between a complex instance and
774 a Fractions instance now raise TypeError instead of returning
775 True/False. This makes Fraction <=> complex comparisons consistent with
776 int <=> complex, float <=> complex, and complex <=> complex comparisons.
777
Antoine Pitrou39b35432010-03-23 00:25:54 +0000778- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
779 some methods (such as oss_mixer_device.fileno()) were not available.
780 Initial patch by Bertrand Janin.
781
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000782- Issue #8205: Remove the "Modules" directory from sys.path when Python is
783 running from the build directory (POSIX only).
784
Antoine Pitrou910bd512010-03-22 20:11:09 +0000785- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
786 didn't support chflags() (for example ZFS under FreeBSD). The error is
787 now silenced.
788
R. David Murrayca2edce2010-03-22 17:48:48 +0000789- Issue #7860: platform.uname now reports the correct 'machine' type
790 when Python is running in WOW64 mode on 64 bit Windows.
791
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000792- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
793 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
794 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000795
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000796- Issue #4282: Fix the main function of the profile module for a non-ASCII
797 script, open the file in binary mode and not in text mode with the default
798 (utf8) encoding.
799
Florent Xicluna54467e02010-03-21 12:29:50 +0000800- Issue #8179: Fix macpath.realpath() on a non-existing path.
801
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000802- Issue #8024: Update the Unicode database to 5.2.
803
Benjamin Peterson00888932010-03-18 22:37:38 +0000804- Issue #8168: py_compile now handles files with utf-8 BOMS.
805
Benjamin Peterson689a5582010-03-18 22:29:52 +0000806- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
807 detected.
808
Martin v. Löwis4b003072010-03-16 13:19:21 +0000809- Issue #6716/2: Backslash-replace error output in compilall.
810
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000811- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
812 with Tcl/Tk-8.5.
813
Matthias Klosec33b9022010-03-16 00:36:26 +0000814- Issue #8140: extend compileall to compile single files. Add -i option.

817 the locale.
818
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000819- The internals of the subprocess module on POSIX systems have been replaced
820 by an extension module (_posixsubprocess) so that the fork()+exec() can be
821 done safely without the possibility of deadlock in multithreaded applications.
822
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000823- subprocess.Popen now has restore_signals and start_new_session features.
824 The default of restore_signals=True is a new behavior compared to earlier
825 Python versions. This means that signals such as SIGPIPE are not ignored
826 by default in subprocesses launched by Python (Issue #1652).
827
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000828- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

838 the replacement were all bytes. Patch by Antoine Pitrou.
839
Gerhard Häringf9cee222010-03-05 15:20:03 +0000840- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure

872
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000873- Issue #6666: fix bug in trace.py that applied the list of directories
874 to be ignored only to the first file. Noted by Bogdan Opanchuk.
875
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000876- Issue #7597: curses.use_env() can now be called before initscr().
877 Noted by Kan-Ru Chen.

885 bytecode file when it was less then 8 bytes.
886
Mark Dickinson84230a12010-02-18 14:49:50 +0000887- Issue #7633: In the decimal module, Context class methods (with the
888 exception of canonical and is_canonical) now accept instances of int
889 and long wherever a Decimal instance is accepted, and implicitly
890 convert that argument to Decimal. Previously only some arguments
891 were converted.
892
R. David Murray1f449142010-02-11 00:15:05 +0000893- Issue #7835: shelve should no longer produce mysterious warnings during

906 specify the compression type.
907
Antoine Pitroub6375f12010-02-04 20:23:24 +0000908- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
909 specified, rather than fall through to AF_PACKET (in the `socket` module).
910 Also, raise ValueError rather than TypeError when an unknown TIPC address
911 type is specified. Patch by Brian Curtin.
912
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000913- Issue #6939: Fix file I/O objects in the `io` module to keep the original
914 file position when calling `truncate()`. It would previously change the
915 file position to the given argument, which goes against the tradition of
916 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
917
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000918- Issue #7610: Reworked implementation of the internal
919 :class:`zipfile.ZipExtFile` class used to represent files stored inside
920 an archive. The new implementation is significantly faster and can
921 be wrapped in a :class:`io.BufferedReader` object for more speedups.
922 It also solves an issue where interleaved calls to `read()` and
923 `readline()` give wrong results. Patch by Nir Aides.
924
Jesse Noller1f0b6582010-01-27 03:36:01 +0000925- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

Victor Stinnere125f132010-05-15 21:04:43 +0000991 MSVC XML Manifest file in text mode so string patterns can be used

1003 object). Patch by Victor Stinner and Florent Xicluna.
1004
Benjamin Petersonbf5ff762009-12-13 19:25:34 +00001005- Issue #7349: Make methods of file objects in the io module accept None as an
1006 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1007 the same as passing no argument.
1008

Nick Coghlan260bd3e2009-11-16 06:49:25 +00001086- Issue #6816: runpy now provides a run_path function that allows Python code
1087 to execute file paths that refer to source or compiled Python files as well
1088 as zipfiles, directories and other valid sys.path entries that contain a
1089 __main__.py file. This allows applications that run other Python scripts to
1090 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001109 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001110 recursive locks as fast as regular non-recursive locks (previously,
1111 they were slower by 10x to 15x).

1131 reading from stdin so that existing input does not confuse it and
1132 lead to incorrect entry or an IOError. It also properly flushes it
1133 afterwards to avoid the terminal echoing the input afterwards on
1134 OSes such as Solaris.

1352 calculating with integer arithmetic instead of float arithmetic internally):
1353 the result is now always correctly rounded, and is equivalent to td /
1354 timedelta(seconds=1).
1355
Mark Dickinson7c186e22010-04-20 22:32:49 +00001356- Issue #2706: Allow division of a timedelta by another timedelta:

1587 user running the tests.

1611 calling methods on the object.
1612
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001613- Issue #7222: Make thread "reaping" more reliable so that reference
1614 leak-chasing test runs give sensible results. The previous method of
1615 reaping threads could return successfully while some Thread objects were
1616 still referenced. This also introduces a new private function:
1617 :func:`_thread._count()`.
1618
R. David Murray27144602009-10-19 15:26:16 +00001619- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1620 longer runs the risk of causing the worker thread to fail.
1621
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001622- Issue #7055: test___all__ now greedily detects all modules which have an
1623 __all__ attribute, rather than using a hardcoded and incomplete list.
1624
R. David Murray0bc11ae2009-10-18 22:18:17 +00001625- Issue #7058: Added save/restore for things like sys.argv and cwd to
1626 runtest_inner in regrtest, with warnings if the called test modifies them,
1627 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001628
Mark Dickinson2e304402009-10-04 18:43:54 +00001629- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1630
Brett Cannon3c273842009-07-20 00:14:29 +00001631- Fixed tests in importlib.test.source.test_abc_loader that were masking
1632 the proper exceptions that should be raised for missing or improper code
1633 object bytecode.
1634
Brett Cannonb49c70c2009-07-15 04:08:33 +00001635- Removed importlib's custom test discovery code and switched to

1644 added to the `Tools/` directory. They were previously living in the
1645 sandbox.

1780
Eric Smith41669ca2009-05-23 14:23:22 +00001781- Issue #6089: Fixed str.format with certain invalid field specifiers
1782 that would raise SystemError.
1783
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001784- Issue #5982: staticmethod and classmethod now expose the wrapped
1785 function with __func__.
1786
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001787- Added support for multiple context managers in the same with-statement.
1788 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001790- Issue #5829: complex("1e500") no longer raises OverflowError. This
1791 makes it consistent with float("1e500") and interpretation of real
1792 and imaginary literals.
1793
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001794- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1795

1797
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001798- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1799 (1) inf and nan strings with trailing whitespace were incorrectly
1800 rejected; (2) parsing of strings representing infinities and nans
1801 was locale aware; and (3) the interpretation of fromhex('-nan')
1802 didn't match that of float('-nan').

1810
R. David Murray1f1b9d32009-05-27 20:56:59 +00001811- Issue #6121: pydoc now ignores leading and trailing spaces in the
1812 argument to the 'help' function.
1813
Georg Brandlfaf41492009-05-26 18:31:11 +00001814- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1815 arguments for strings with a space in them.
1816
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001817- collections.namedtuple() was not working with the following field
1818 names: cls, self, tuple, itemgetter, and property.
1819
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001820- In unittest, using a skipping decorator on a class is now equivalent to
1821 skipping every test on the class. The ClassTestSuite class has been removed.
1822
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001823- Issue #6050: Don't fail extracting a directory from a zipfile if
1824 the directory already exists.
1825
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001826- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1827 than an int, which makes some operations possible under 64-bit Linux (e.g.
1828 DN_MULTISHOT with F_NOTIFY).
1829
Antoine Pitrou716c4442009-05-23 19:04:03 +00001830- Issue #5761: Add the name of the underlying file to the repr() of various

1832
R. David Murraycaa27b72009-05-23 18:49:56 +00001833- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1834 by Musashi Tamura, tests by Marcin Bachry.
1835
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001836- Issue #1983: Fix functions taking or returning a process identifier to use
1837 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1838 a process identifier type wider than the standard C integer type.
1839
R. David Murray87e20742009-05-23 01:30:26 +00001840- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1851
Antoine Pitroue4501852009-05-14 18:55:55 +00001852- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1853 library. This means, for example, that opening an UTF-16 text file in
1854 append mode doesn't add a BOM at the end of the file if the file isn't
1855 empty.
1856
R. David Murray74b89242009-05-13 17:33:03 +00001857- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1858 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1859 corrects a pydoc regression.
1860
R. David Murray99352742009-05-07 18:24:38 +00001861- Issue 5955: aifc's close method did not close the file it wrapped,
1862 now it does. This also means getfp method now returns the real fp.
1863
Benjamin Peterson932073a2009-05-23 16:14:33 +00001864Installation
1865------------

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001900What's New in Python 3.1 beta 1?
1901================================
1902
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001903*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001904
1905Core and Builtins
1906-----------------
1907
Mark Dickinson865e01a2009-05-07 16:37:01 +00001908- Issue #5914: Add new C API function PyOS_string_to_double, and
1909 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1910
Eric Smith741191f2009-05-06 13:08:15 +00001911- Issue #3382: float.__format__, complex.__format__, and %-formatting
1912 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1913 affects nan -> NAN and inf -> INF.
1914
Mark Hammond5a607a32009-05-06 08:04:54 +00001915- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1916 in all operations, including splitdrive, split, etc. splitunc() now issues
1917 a PendingDeprecation warning.
1918
Eric Smith63376222009-05-05 14:04:18 +00001919- Issue #5920: For float.__format__, change the behavior with the
1920 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1921 to be like 'g' but with at least one decimal point and with a
1922 default precision of 12. Previously, the behavior the same but with
1923 a default precision of 6. This more closely matches str(), and
1924 reduces surprises when adding alignment flags to the empty
1925 presentation type. This also affects the new complex.__format__ in
1926 the same way.
1927
Martin v. Löwis011e8422009-05-05 04:43:17 +00001928- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1929
R. David Murrayb18500d2009-05-04 22:59:07 +00001930- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1931 shadowed by classtype's, even if it was None. property now
1932 inserts the __doc__ into the subclass instance __dict__.
1933
Antoine Pitrou244651a2009-05-04 18:56:13 +00001934- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1935 sequences. Patch by Nick Barnes and Victor Stinner.
1936
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001937- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001938
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001939- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1940 received a new method, detach(). detach() disconnects the underlying stream
1941 from the buffer or text IO and returns it.
1942
Mark Dickinson33841c32009-05-01 15:37:04 +00001943- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1944 floats with absolute value over 1e50. Also remove length
1945 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1946 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001947
Eric Smith741191f2009-05-06 13:08:15 +00001948- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001949 format(complex(1, 2./3), '.5') now produces a sensible result.
1950
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001951- Issue #5864: Fix empty format code formatting for floats so that it
1952 never gives more than the requested number of significant digits.
1953
Eric Smith6dc46f52009-04-27 20:39:49 +00001954- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1955 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1956
Eric Smithcc32a112009-04-26 21:35:14 +00001957- Issue #5835: Deprecate PyOS_ascii_formatd.
1958
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001959- Issue #4971: Fix titlecase for characters that are their own
1960 titlecase, but not their own uppercase.
1961
Benjamin Peterson193152c2009-04-25 01:08:45 +00001962- Issue #5283: Setting __class__ in __del__ caused a segfault.
1963
Mark Dickinsonad476da2009-04-23 19:14:16 +00001964- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1965 z involves nans, infs or negative zeros.
1966
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001967- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001968
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001969- Issue #1869 (and many duplicates): make round(x, n) correctly
1970 rounded for a float x, by using the decimal <-> binary conversions
1971 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1972 consistently agrees with format(x, '.2f').
1973
Benjamin Petersonae937c02009-04-18 20:54:08 +00001974- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1975 some builtin types.
1976
Eric Smith0923d1d2009-04-16 20:16:10 +00001977- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1978
Eric Smith35e84722009-04-16 20:21:28 +00001979- Issue #5515: str.format() type 'n' combined with commas and leading
1980 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001981
1982- Implement PEP 378, Format Specifier for Thousands Separator, for
1983 floats.
1984
Mark Dickinson3370cce2009-04-17 22:40:53 +00001985- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001986 1e11, not 1e12. This avoids printing 13 significant digits in
1987 situations where only 12 of them are correct. Example problem
1988 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1989 long time.)
1990
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001991- Issue #1580: On most platforms, use a 'short' float repr: for a
1992 finite float x, repr(x) now outputs a string based on the shortest
1993 sequence of decimal digits that rounds to x. Previous behaviour was
1994 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001995 Another minor difference is that the new repr switches to
1996 exponential notation at 1e16 instead of the previous 1e17; this
1997 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001998
1999 There's a new sys attribute sys.float_repr_style, which takes
2000 the value 'short' to indicate that we're using short float repr,
2001 and 'legacy' if the short float repr isn't available for one
2002 reason or another.
2003
2004 The float repr change involves incorporating David Gay's 'perfect
2005 rounding' code into the Python core (it's in Python/dtoa.c). As a
2006 secondary consequence, all string-to-float and float-to-string
2007 conversions (including all float formatting operations) will be
2008 correctly rounded on these platforms.
2009
2010 See issue 1580 discussions for details of platforms for which
2011 this change does not apply.
2012
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002013- Issue #5759: float() didn't call __float__ on str subclasses.
2014
Georg Brandlabc38772009-04-12 15:51:51 +00002015- The string.maketrans() function is deprecated; there is a new static method
2016 maketrans() on the bytes and bytearray classes. This removes confusion about
2017 the types string.maketrans() is supposed to work with, and mirrors the
2018 methods available on the str class.
2019
R. David Murraydc6da8a2009-04-09 22:16:43 +00002020- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2021 its clarity and its speed.
2022
Matthias Klose091c7b12009-04-07 13:24:27 +00002023- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2024 to avoid compiler warnings.
2025
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002026- Issue #3739: The unicode-internal encoder now reports the number of characters
2027 consumed like any other encoder (instead of the number of bytes).

2342 optional module state data.
2343
Mark Dickinson8055afd2009-01-17 10:04:45 +00002344- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2345 type to (void *).
2346
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002347- Issue #4935: The overflow checking code in the expandtabs() method common
2348 to str, bytes and bytearray could be optimized away by the compiler, letting
2349 the interpreter segfault instead of raising an error.
2350
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002351- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2352 __next__ method.
2353
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002354- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2355 function no longer attempt to call the __long__ slot to convert an object
2356 to an integer. Only the __int__ and __trunc__ slots are examined.

2361
Antoine Pitrouab868312009-01-10 15:40:25 +00002362- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2363 common cases are optimized thanks to a dedicated fast path and a moderate
2364 amount of loop unrolling.
2365
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002366- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2367 collecting the oldest generation) so that allocating lots of objects without
2368 destroying them does not show quadratic performance. Based on a proposal by
2369 Martin von Löwis at
2370 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2371
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002372- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002373 having been closed (for instance, a read() call could return some
2374 previously buffered data). Patch by Dmitry Vasiliev.
2375
Antoine Pitrou05608432009-01-09 18:53:14 +00002376- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2377 flag to work properly. Furthermore, when specifying -u, the text stdout
2378 and stderr streams have line-by-line buffering enabled (the default being
2379 to buffer arbitrary chunks of data).
2380
Raymond Hettinger35631532009-01-09 03:58:09 +00002381- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2382 instead of ints (reducing its size from 4 to 8 times thereby reducing
2383 Python's overall memory).
2384
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002385- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2386 an existing .py counterpart, override the co_filename attributes of all
2387 code objects if the original filename is obsolete (which can happen if the
2388 file has been renamed, moved, or if it is accessed through different paths).
2389 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2390
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002391- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2392 one byte. Also fixes the meaning of len() so that it returns the number of
2393 items, rather than the size in bytes.
2394
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002395- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2396
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002397- Issue #4747: When the terminal does not use utf-8, executing a script with
2398 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2399
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002400- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

2404 did not get collected.
2405
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002406- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2407 where the tp_hash and tp_dict slots are both NULL.
2408
Georg Brandlccc47b62008-12-28 11:44:14 +00002409- Issue #4759: None is now allowed as the first argument of
2410 bytearray.translate(). It was always allowed for bytes.translate().
2411
Skip Montanaro80072cb2008-12-23 03:51:14 +00002412- Added test case to ensure attempts to read from a file opened for writing
2413 fail.

2419
Antoine Pitrou621601a2008-12-17 23:18:19 +00002420- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

Mark Dickinsonda2706b2008-12-11 18:03:03 +00002426- Issue #2173: When getting device encoding, check that return value of
2427 nl_langinfo is not the empty string. This was causing silent build
2428 failures on OS X.
2429
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002430- Issue #4597: Fixed several opcodes that weren't always propagating
2431 exceptions.
2432
2433- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002434 context manager returns a value that cannot be converted to a bool.
2435
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002436- Issue #4445: Replace "sizeof(PyBytesObject)" with
2437 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2438 bytes instances. On a typical machine this saves 3 bytes of memory
2439 (on average) per allocation of a bytes instance.
2440
Christian Heimesa872de52008-12-05 08:26:55 +00002441- Issue #4533: File read operation was dreadfully slow due to a slowly
2442 growing read buffer. Fixed by using the same growth rate algorithm as
2443 Python 2.x.
2444
Antoine Pitrou5504e892008-12-06 21:27:53 +00002445- Issue #4509: Various issues surrounding resize of bytearray objects to
2446 which there are buffer exports (e.g. memoryview instances).
2447
Georg Brandlf9734072008-12-07 15:30:06 +00002448- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2449 method on file objects with closefd=False. The file descriptor is still
2450 kept open but the file object behaves like a closed file. The ``FileIO``
2451 object also got a new readonly attribute ``closefd``.

2459
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002460- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2461 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2462 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2463 of using the replace error handler in PyUnicode_DecodeUTF8().
