12Core and Builtins
13-----------------
14
Ezio Melotti57221d02010-07-01 07:32:02 +000015- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
16 start byte and the continuation byte(s) are now considered invalid, instead
17 of the number of bytes specified by the start byte.
18 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
19 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
20 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
21 Previous versions returned a single u'\ufffd'.
22
Mark Dickinson50b79a82010-06-30 11:13:36 +000023- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real
24 part -0.0 rather than 0.0. So "-7j" is now exactly equivalent to
25 "-(7j)".
26
Benjamin Peterson88968ad2010-06-25 19:30:21 +000027- Be more specific in error messages about positional arguments.
28
Victor Stinner4aae1eb2010-06-24 22:08:25 +000029- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
30 objects, as described in the documentation.
31
Victor Stinner0fe25a42010-06-17 23:08:50 +000032- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000033 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
34 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000035
Mark Dickinsond35a32e2010-06-17 12:33:22 +000036- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
37 compilation code dealing with unary minus applied to a constant.
38 The removed code was mutating the ST, causing a second compilation
39 to fail.
40
Victor Stinner554f3f02010-06-16 23:33:54 +000041- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
42 mode raises unicode errors. The encoder only supports "strict" and "replace"
43 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000044 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000045
Victor Stinner25e8ec42010-06-25 00:02:38 +000046- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
47 "w*" format instead. Add tests for "w*" format.
48
Victor Stinner06e49dd2010-06-13 18:21:50 +000049- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
50 formats if the string contains a null byte/character. Write unit tests for
51 string formats.
52
Nick Coghlan5e76e942010-06-12 13:42:46 +000053- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
54 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
55 location of the raised exception.
56
Victor Stinner313a1202010-06-11 23:56:51 +000057- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
58 filenames and enable os.fsencode().
59
Benjamin Peterson285a6892010-06-22 19:21:52 +000060- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
61
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000062- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
63 the interpreter with characters outside the Basic Multilingual Plane
64 (higher than 0x10000).
65
Mark Dickinsonc7301312010-06-10 16:05:10 +000066- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
67 raise TypeError instead of giving a DeprecationWarning when a float
68 is parsed using the 'L' code (for long long). (All other integer
69 codes already raise TypeError in this case.)
70
Victor Stinner600d3be2010-06-10 12:00:55 +000071- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
72 enable shortcuts for upper case encoding name. Add also a shortcut for
73 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
74
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000075- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
76 doesn't support "char buffer" anymore in Python3.
77
78- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
79 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
80 like bytearray.
81
Victor Stinner33109a12010-05-28 21:55:10 +000082- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
83 used anymore and it was never documented.
84
Benjamin Peterson95304522010-06-08 14:57:22 +000085- In the str.format(), raise a ValueError when indexes to arguments are too
86 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000087
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000088- Issue #2844: Make int('42', n) consistently raise ValueError for
89 invalid integers n (including n = -909).
90
Mark Dickinsondc787d22010-05-23 13:33:13 +000091- Issue #8188: Introduce a new scheme for computing hashes of numbers
92 (instances of int, float, complex, decimal.Decimal and
93 fractions.Fraction) that makes it easy to maintain the invariant
94 that hash(x) == hash(y) whenever x and y have equal value.
95
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000096- Issue #8748: Fix two issues with comparisons between complex and integer
97 objects. (1) The comparison could incorrectly return True in some cases
98 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
99 (2) The comparison raised an OverflowError for large integers, leading
100 to unpredictable exceptions when combining integers and complex objects
101 in sets or dicts.
102
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000103- Issue #8766: Initialize _warnings module before importing the first module.
104 Fix a crash if an empty directory called "encodings" exists in sys.path.
105
Victor Stinner9ca9c252010-05-19 16:53:30 +0000106- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
107 encoding and surrogateespace error handler instead of the locale encoding to
108 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
109
Victor Stinner372ac5e2010-05-17 01:26:01 +0000110- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
111 (instead of strict) error handler to escape surrogates
112
Victor Stinnerae6265f2010-05-15 16:27:27 +0000113- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
114 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000115 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
116 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000117
Victor Stinner59e62db2010-05-15 13:14:32 +0000118- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
119 error handler, not only the default error handler (strict)
120
Victor Stinnerb744ba12010-05-15 12:27:16 +0000121- Issue #8610: Load file system codec at startup, and display a fatal error on
122 failure. Set the file system encoding to utf-8 (instead of None) if getting
123 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
124
Victor Stinner0964ee12010-04-30 16:48:45 +0000125- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
126 PyUnicode_FromString() to support surrogates in the filename and use the
127 right encoding
128
Georg Brandl8569e582010-05-19 20:57:08 +0000129- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
130
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000131- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
132
Benjamin Petersonfb886362010-04-24 18:21:17 +0000133- Issue #8419: Prevent the dict constructor from accepting non-string keyword
134 arguments.
135
Victor Stinner14284c22010-04-23 12:02:30 +0000136- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
137 indirectly Python signal handlers anymore because mywrite() ignores
138 exceptions (KeyboardInterrupt)
139
Victor Stinner31be90b2010-04-22 19:38:16 +0000140- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
141 unicode string (eg. backslashreplace)
142
Victor Stinnerdcb24032010-04-22 12:08:36 +0000143- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
144 you have to convert your bytearray filenames to bytes
145
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000146- Issue #7332: Remove the 16KB stack-based buffer in
147 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
148 benefit compared to the dynamic memory allocation fallback. Patch by
149 Charles-François Natali.
150
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000151- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
152 passed to bytes or bytearray.
153
Philip Jenvey0805ca32010-04-07 04:04:10 +0000154- Issue #7301: Add environment variable $PYTHONWARNINGS.
155
Benjamin Petersond856ab62010-04-06 21:55:16 +0000156- Issue #8329: Don't return the same lists from select.select when no fds are
157 changed.
158
Mark Dickinson3318d292010-04-06 16:53:17 +0000159- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
160 on 64-bit machines. The shift count for either left or right shift is
161 permitted to be up to sys.maxsize.
162
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000163- Ensure that tokenization of identifiers is not affected by locale.

170 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000171
Victor Stinner120c2122010-03-25 00:30:28 +0000172- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
173 is unknown
174

176
Mark Dickinsond59b4162010-03-13 11:34:40 +0000177- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
178 PyMemberDefs could produce an internal error; raise TypeError instead.
179
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000180- Issue #7845: Rich comparison methods on the complex type now return
181 NotImplemented rather than raising a TypeError when comparing with an
182 incompatible type; this allows user-defined classes to implement their own
183 comparisons with complex.
184
Victor Stinner52f6dd72010-03-12 14:45:56 +0000185- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
186 (SIGINT). If an error occurs while importing the site module, the error is
187 printed and Python exits. Initialize the GIL before importing the site
188 module.
189
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000190- Issue #7173: Generator finalization could invalidate sys.exc_info().

193 a fatal error in low memory condition.
194
Victor Stinner6aa278e2010-03-03 00:18:49 +0000195- Issue #7820: The parser tokenizer restores all bytes in the right if
196 the BOM check fails.
197
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000198- Handle errors from looking up __prepare__ correctly.
199
Larry Hastings1373a072010-02-24 22:49:58 +0000200- Issue #5939: Add additional runtime checking to ensure a valid capsule
201 in Modules/_ctypes/callproc.c.
202

204 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
205 strings.
206
Eric Smithabb28c62010-02-23 00:22:24 +0000207- Issue #6902: Fix problem with built-in types format incorrectly with

216 deprecations.
217
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000218- Issue #7385: Fix a crash in `MemoryView_FromObject` when
219 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
220
Mark Dickinsonbc099642010-01-29 17:27:24 +0000221- Issue #7788: Fix an interpreter crash produced by deleting a list
222 slice with very large step value.
223
Eric Smithf7bb5782010-01-27 00:44:57 +0000224- Issue #7766: Change sys.getwindowsversion() return value to a named
225 tuple and add the additional members returned in an OSVERSIONINFOEX
226 structure. The new members are service_pack_major, service_pack_minor,
227 suite_mask, and product_type.
228
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000229- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
230 could crash in many places because of the PyByteArray_AS_STRING() macro
231 returning NULL. The macro now returns a statically allocated empty
232 string instead.
233
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000234- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
235 where the right hand operand is a set of constants, by turning the set into
236 a frozenset and pre-building it as a constant. The comparison operation
237 is made against the constant instead of building a new set each time it is
238 executed (a similar optimization already existed which turned a list of
239 constants into a pre-built tuple). Patch and additional tests by Dave
240 Malcolm.
241
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000242- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

247 alpha 2, including: (1) a serious 'wrong output' bug that could
248 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
249 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000250 strings corresponding to subnormal values, (3) a memory leak for
251 some values large enough to cause overflow, and (4) a number of
252 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000253
Benjamin Petersonaea44282010-01-04 01:10:28 +0000254- The __complex__ method is now looked up on the class of instances to make it
255 consistent with other special methods.

264 negative zero) in ** operator. The behaviour now conforms to that
265 described in C99 Annex F.
266
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000267- Issue #1811: improve accuracy and cross-platform consistency for
268 true division of integers: the result of a/b is now correctly
269 rounded for ints a and b (at least on IEEE 754 platforms), and in
270 particular does not depend on the internal representation of an int.
271
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000272- Issue #6834: replace the implementation for the 'python' and 'pythonw'
273 executables on OSX.
274
275 These executables now work properly with the arch(1) command:
276 ``arch -ppc python`` will start a universal binary version of python
277 in PPC mode (unlike previous releases).
278
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000279- Issue #7466: segmentation fault when the garbage collector is called

294 implement the relevant rich comparison methods.
295
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000296- Issue #7298: fixes for range and reversed(range(...)). Iteration
297 over range(a, b, c) incorrectly gave an empty iterator when a, b and
298 c fit in C long but the length of the range did not. Also fix
299 several cases where reversed(range(a, b, c)) gave wrong results, and
300 fix a refleak for reversed(range(a, b, c)) with large arguments.
301
Raymond Hettingerfc438512009-11-01 20:55:33 +0000302- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitrou152efa22010-05-16 18:19:27 +0000608- Issue #8550: Add first class ``SSLContext`` objects to the ssl module.
609
Antoine Pitrou53b21662010-05-11 23:46:02 +0000610- Issue #8681: Make the zlib module's error messages more informative when
611 the zlib itself doesn't give any detailed explanation.
612
Mark Dickinson81fece22010-05-11 13:34:35 +0000613- The audioop module now supports sound fragments of length greater
614 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
615
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000616- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
617 class.
618
Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000619- Issue #8664: In py_compile, create __pycache__ when the compiled path is
620 given.
621
Victor Stinner449c4662010-05-08 11:10:09 +0000622- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
623 for use in the file system, environment variables or the command line.
624
Antoine Pitrou89562712010-05-07 17:04:02 +0000625- Issue #8571: Fix an internal error when compressing or decompressing a
626 chunk larger than 1GB with the zlib module's compressor and decompressor
627 objects.
628
Benjamin Peterson225168e2010-05-06 22:29:53 +0000629- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
630 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
631 file system encoding with the surrogateescape error handler (instead of
632 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000633
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000634- Issue #8573: asyncore _strerror() function might throw ValueError.
635
Victor Stinnere125f132010-05-15 21:04:43 +0000636- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
637 error messages when accessing undefined class attributes because of the cheap
638 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000639 The cheap inheritance has been deprecated.
640
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000641- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
642 Patch by Tres Seaver.
643
Victor Stinnerde629d42010-05-05 21:43:57 +0000644- Issue #8390: tarfile uses surrogateespace as the default error handler
645 (instead of replace in read mode or strict in write mode)
646
Barry Warsaw83d89982010-05-05 16:18:31 +0000647- Issue #7755: Use an unencumbered audio file for tests.
648
Ronald Oussorenac764d32010-05-05 15:32:33 +0000649- Issue #8621: uuid.uuid4() returned the same sequence of values in the

651
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000652- Issue #8567: Fix precedence of signals in Decimal module: when a
653 Decimal operation raises multiple signals and more than one of those
654 signals is trapped, the specification determines the order in which
655 the signals should be handled. In many cases this order wasn't
656 being followed, leading to the wrong Python exception being raised.
657
Antoine Pitrou6be88762010-05-03 16:48:20 +0000658- Issue #7865: The close() method of :mod:`io` objects should not swallow
659 exceptions raised by the implicit flush(). Also ensure that calling
660 close() several times is supported. Patch by Pascal Chambon.
661
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000662- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
663 gc.DEBUG_STATS.
664
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000665- Issue #8354: The siginterrupt setting is now preserved for all signals,
666 not just SIGCHLD.
667
Georg Brandl25106ce2010-05-21 21:49:47 +0000668- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000669 webbrowser.get("safari").
670
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000671- Issue #8464: tarfile no longer creates files with execute permissions set
672 when mode="w|" is used.
673
Antoine Pitroubf043492010-04-29 10:11:46 +0000674- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
675 of the Linux kernel. Patch by Yaniv Aknin.
676
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000677- Issue #8295: Added shutil.unpack_archive.
678
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000679- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
680 It should correctly return an empty response now.
681
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000682- Issue #8546: Reject None given as the buffering argument to _pyio.open.
683
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000684- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
685 Sridhar Ratnakumar.
686
R. David Murrayad78d152010-04-27 02:45:53 +0000687- Issue #6656: fix locale.format_string to handle escaped percents
688 and mappings.
689
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000690- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
691 where the method could block indefinitely if called just before the
692 event loop started running. This also fixes the occasional freezes
693 witnessed in test_httpservers.
694
Antoine Pitrou40f08742010-04-24 22:04:40 +0000695- Issue #8524: When creating an SSL socket, the timeout value of the
696 original socket wasn't retained (instead, a socket with a positive timeout
697 would be turned into a non-blocking SSL socket).
698
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000699- Issue #5103: SSL handshake would ignore the socket timeout and block
700 indefinitely if the other end didn't respond.
701
702- The do_handshake() method of SSL objects now adjusts the blocking mode of
703 the SSL structure if necessary (as other methods already do).
704
Victor Stinner13bb71c2010-04-23 21:41:56 +0000705- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
706 and bytes strings for environment keys and values
707
Victor Stinner4d078042010-04-23 19:28:32 +0000708- Issue #8467: Pure Python implementation of subprocess encodes the error
709 message using surrogatepass error handler to support surrogates in the
710 message
711
Victor Stinner349fd522010-04-23 10:56:17 +0000712- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
713
Sean Reifscheider13daf122010-04-23 09:29:52 +0000714- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
715 the string "python" as the *ident*. openlog() arguments are all optional
716 and keywords.
717
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000718- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
719 a non-infinite timeout. Also make that method friendlier with applications
720 wanting to continue using the socket in clear-text mode, by disabling
721 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
722
Antoine Pitrou7062db82010-04-22 13:30:10 +0000723- Issue #8496: make mailcap.lookup() always return a list, rather than an
724 iterator. Patch by Gregory Nofi.
725
Victor Stinner35466c52010-04-22 11:23:23 +0000726- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
727 collation name contains a surrogate character.
728
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000729- Issue #8484: Load all ciphers and digest algorithms when initializing
730 the _ssl extension, such that verification of some SSL certificates
731 doesn't fail because of an "unknown algorithm".
732
Tarek Ziadéfb437512010-04-20 08:57:33 +0000733- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
734
Victor Stinnere125f132010-05-15 21:04:43 +0000735- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000736 shutil.copytree.
737
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000738- Issue #4814: timeout parameter is now applied also for connections resulting
739 from PORT/EPRT commands.
740
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000741- Issue #8463: added missing reference to bztar in shutil's documentation.
742
Ronald Oussoren84151202010-04-18 20:46:11 +0000743- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
744 (as long as the user didn't specify 'automatic proxy configuration').
745
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000746- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
747 code as stated in RFC-959 at chapter 5.4.
748
Victor Stinner738446f02010-04-18 00:00:44 +0000749- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
750 surrogates.
751
Antoine Pitrou0454af92010-04-17 23:51:58 +0000752- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000753 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000754
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000755- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
756 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
757
Victor Stinner0e59cc32010-04-16 23:49:32 +0000758- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
759 the current working directory.
760
Victor Stinner5bfe1462010-04-16 13:28:05 +0000761- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
762 using backslashreplace error handler
763
Victor Stinnercfa72782010-04-16 11:45:13 +0000764- Issue #8412: os.system() now accepts bytes, bytearray and str with

768 Locke and Hans Ulrich Niedermann.
769
R. David Murrayd48739f2010-04-14 18:59:18 +0000770- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
771
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000772- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
773 module now takes an optional timeout argument in seconds. Timeout support
774 relies on the system threading library, so as to avoid a semi-busy wait
775 loop.
776
Victor Stinner485fb562010-04-13 11:07:24 +0000777- Issue #8383: pickle and pickletools use surrogatepass error handler when
778 encoding unicode as utf8 to support lone surrogates and stay compatible with
779 Python 2.x and 3.0
780
R. David Murrayb2416e52010-04-12 16:58:02 +0000781- Issue #7585: difflib context and unified diffs now place a tab between
782 filename and date, conforming to the 'standards' they were originally
783 designed to follow. This improves compatibility with patch tools.
784
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000785- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
786 character sets will now consistently use a Content-Transfer-Encoding of
787 7bit rather than sometimes being marked as 8bit.
788
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000789- Issue #8375: test_distutils now checks if the temporary directory are still
790 present before it cleans them.
791
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000792- Issue #8374: Update the internal alias table in the :mod:`locale` module
793 to cover recent locale changes and additions.
794
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000795- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
796 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
797 and `ssl.OPENSSL_VERSION_NUMBER`.
798
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000799- Add functools.total_ordering() and functools.cmp_to_key().
800
Mark Dickinson089b00c2010-04-03 15:51:03 +0000801- Issue #8257: The Decimal construct now accepts a float instance
802 directly, converting that float to a Decimal of equal value:
803
804 >>> Decimal(1.1)
805 Decimal('1.100000000000000088817841970012523233890533447265625')
806
Mark Dickinson98127c32010-04-03 11:18:52 +0000807- Issue #8294: The Fraction constructor now accepts Decimal and float
808 instances directly.
809
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000810- Issue #7279: Comparisons involving a Decimal signaling NaN now
811 signal InvalidOperation instead of returning False. (Comparisons
812 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
813 are now hashable; Decimal signaling NaNs remain unhashable.
814
815- Issue #2531: Comparison operations between floats and Decimal
816 instances now return a result based on the numeric values of the
817 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000818 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000819 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000820
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000821- Added a subtract() method to collections.Counter().
822
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000823- Issue #8233: When run as a script, py_compile.py optionally takes a single
824 argument `-` which tells it to read files to compile from stdin. Each line
825 is read on demand and the named file is compiled immediately. (Original
826 patch by Piotr Ożarowski).
827
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000828- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
829 form feed (0x0C) are now considered linebreaks, as specified in Unicode
830 Standard Annex #14. See issue #7643.
831 http://www.unicode.org/reports/tr14/
832
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000833- Comparisons using one of <, <=, >, >= between a complex instance and
834 a Fractions instance now raise TypeError instead of returning
835 True/False. This makes Fraction <=> complex comparisons consistent with
836 int <=> complex, float <=> complex, and complex <=> complex comparisons.
837
Antoine Pitrou39b35432010-03-23 00:25:54 +0000838- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
839 some methods (such as oss_mixer_device.fileno()) were not available.
840 Initial patch by Bertrand Janin.
841
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000842- Issue #8205: Remove the "Modules" directory from sys.path when Python is
843 running from the build directory (POSIX only).
844
Antoine Pitrou910bd512010-03-22 20:11:09 +0000845- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
846 didn't support chflags() (for example ZFS under FreeBSD). The error is
847 now silenced.
848
R. David Murrayca2edce2010-03-22 17:48:48 +0000849- Issue #7860: platform.uname now reports the correct 'machine' type
850 when Python is running in WOW64 mode on 64 bit Windows.
851
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000852- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
853 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
854 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000855
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000856- Issue #4282: Fix the main function of the profile module for a non-ASCII
857 script, open the file in binary mode and not in text mode with the default
858 (utf8) encoding.
859
Florent Xicluna54467e02010-03-21 12:29:50 +0000860- Issue #8179: Fix macpath.realpath() on a non-existing path.
861
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000862- Issue #8024: Update the Unicode database to 5.2.
863
Benjamin Peterson00888932010-03-18 22:37:38 +0000864- Issue #8168: py_compile now handles files with utf-8 BOMS.
865
Benjamin Peterson689a5582010-03-18 22:29:52 +0000866- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
867 detected.
868
Martin v. Löwis4b003072010-03-16 13:19:21 +0000869- Issue #6716/2: Backslash-replace error output in compilall.
870
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000871- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
872 with Tcl/Tk-8.5.
873
Matthias Klosec33b9022010-03-16 00:36:26 +0000874- Issue #8140: extend compileall to compile single files. Add -i option.
875
Matthias Klose82f60912010-03-15 13:46:04 +0000876- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
877 the locale.
878
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000879- The internals of the subprocess module on POSIX systems have been replaced
880 by an extension module (_posixsubprocess) so that the fork()+exec() can be
881 done safely without the possibility of deadlock in multithreaded applications.
882
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000883- subprocess.Popen now has restore_signals and start_new_session features.
884 The default of restore_signals=True is a new behavior compared to earlier
885 Python versions. This means that signals such as SIGPIPE are not ignored
886 by default in subprocesses launched by Python (Issue #1652).
887
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000888- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
889 cElementTree module is updated too.
890
Victor Stinnerb33062c2010-03-12 14:27:16 +0000891- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
892 an non existent program name and Python is unable to retrieve the real
893 program name
894
Florent Xiclunaa4707382010-03-11 00:05:17 +0000895- Issue #7880: Fix sysconfig when the python executable is a symbolic link.
896
Ezio Melottib92ed7c2010-03-06 15:24:08 +0000897- Issue #6509: fix re.sub to work properly when the pattern, the string, and
898 the replacement were all bytes. Patch by Antoine Pitrou.
899
Gerhard Häringf9cee222010-03-05 15:20:03 +0000900- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
901 bugs and allows loading SQLite extensions from shared libraries.

1147 to execute file paths that refer to source or compiled Python files as well
1148 as zipfiles, directories and other valid sys.path entries that contain a
1149 __main__.py file. This allows applications that run other Python scripts to
1150 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001169 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001170 recursive locks as fast as regular non-recursive locks (previously,

1191 reading from stdin so that existing input does not confuse it and
1192 lead to incorrect entry or an IOError. It also properly flushes it

Brett Cannon69194272009-07-20 04:23:48 +00001326- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
1327 loaders that allow for modules to be executed. Both importlib.abc.PyLoader

1330
Brett Cannon64ef00f2009-07-20 03:19:18 +00001331- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001383- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1384 10,000. Prior to this change, timezone adjustment in utctimetuple()
1385 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1386 raised in these edge cases.
1387
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001388- Issue #6641: The ``datetime.strptime`` method now supports the
1389 ``%z`` directive. When the ``%z`` directive is present in the
1390 format string, an aware ``datetime`` object is returned with
1391 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1392 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1393 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1394 without ``%z`` is discarded.
1395
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001396- Issue #5094: The ``datetime`` module now has a simple concrete class
1397 implementing ``datetime.tzinfo`` interface. Instances of the new
1398 class, ``datetime.timezone``, return fixed name and UTC offset from
1399 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1400 method always returns ``None``. A class attribute, ``utc`` contains
1401 an instance representing the UTC timezone. Original patch by Rafe
1402 Kaplan.
1403
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001404- Issue #8973: Add __all__ to struct module; this ensures that

1406
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001407- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001408 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001409 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00001410
Stefan Kraha3ac44e2010-06-08 14:00:52 +00001411- Issue #7384: If the system readline library is linked against ncurses,
1412 the curses module must be linked against ncurses as well. Otherwise it
1413 is not safe to load both the readline and curses modules in an application.
1414
Brian Curtin60853212010-05-26 17:43:50 +00001415- Issue #2810: Fix cases where the Windows registry API returns

1417
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001418- Issue #8692: Optimize math.factorial: replace the previous naive
1419 algorithm with an improved 'binary-split' algorithm that uses fewer
1420 multiplications and allows many of the multiplications to be
1421 performed using plain C integer arithmetic instead of PyLong
1422 arithmetic. Also uses a lookup table for small arguments.
1423
Mark Dickinson85eacea2010-05-10 16:27:45 +00001424- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1425 overflow checks in the audioop module.
1426
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001427- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1428 calculating with integer arithmetic instead of float arithmetic internally):
1429 the result is now always correctly rounded, and is equivalent to td /
1430 timedelta(seconds=1).
1431
Mark Dickinson7c186e22010-04-20 22:32:49 +00001432- Issue #2706: Allow division of a timedelta by another timedelta:
1433 timedelta / timedelta, timedelta % timedelta, timedelta // timedelta
1434 and divmod(timedelta, timedelta) are all supported.
1435
Victor Stinnerfebecd82010-04-16 12:07:30 +00001436- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
1437
Mark Dickinsonc5935772010-04-03 15:54:36 +00001438- Issue #8300: When passing a non-integer argument to struct.pack with any
1439 integer format code, struct.pack first attempts to convert the non-integer
1440 using its __index__ method. If that method is non-existent or raises
1441 TypeError it goes on to try the __int__ method, as described below.
1442
Matthias Klosea8349752010-03-15 13:25:28 +00001443- Issue #8142: Update libffi to the 3.0.9 release.

R. David Murrayba311052009-12-04 00:09:14 +00001664 file in the Lib/test directory, which might be read-only for the
1665 user running the tests.

1692 leak-chasing test runs give sensible results. The previous method of
1693 reaping threads could return successfully while some Thread objects were
1694 still referenced. This also introduces a new private function:
1695 :func:`_thread._count()`.
1696
R. David Murray27144602009-10-19 15:26:16 +00001697- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1698 longer runs the risk of causing the worker thread to fail.
1699
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001700- Issue #7055: test___all__ now greedily detects all modules which have an
1701 __all__ attribute, rather than using a hardcoded and incomplete list.

1705 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001706
Mark Dickinson2e304402009-10-04 18:43:54 +00001707- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1708
Brett Cannon3c273842009-07-20 00:14:29 +00001709- Fixed tests in importlib.test.source.test_abc_loader that were masking
1710 the proper exceptions that should be raised for missing or improper code
1711 object bytecode.
1712
Brett Cannonb49c70c2009-07-15 04:08:33 +00001713- Removed importlib's custom test discovery code and switched to

2000 default precision of 12. Previously, the behavior the same but with
2001 a default precision of 6. This more closely matches str(), and

2039
Benjamin Peterson193152c2009-04-25 01:08:45 +00002040- Issue #5283: Setting __class__ in __del__ caused a segfault.
2041
Mark Dickinsonad476da2009-04-23 19:14:16 +00002042- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2043 z involves nans, infs or negative zeros.
2044
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002045- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002046
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002047- Issue #1869 (and many duplicates): make round(x, n) correctly
2048 rounded for a float x, by using the decimal <-> binary conversions
2049 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2050 consistently agrees with format(x, '.2f').
2051
Benjamin Petersonae937c02009-04-18 20:54:08 +00002052- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2053 some builtin types.
2054
Eric Smith0923d1d2009-04-16 20:16:10 +00002055- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2056
Eric Smith35e84722009-04-16 20:21:28 +00002057- Issue #5515: str.format() type 'n' combined with commas and leading
2058 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002059
2060- Implement PEP 378, Format Specifier for Thousands Separator, for
2061 floats.
2062
Mark Dickinson3370cce2009-04-17 22:40:53 +00002063- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002064 1e11, not 1e12. This avoids printing 13 significant digits in
2065 situations where only 12 of them are correct. Example problem
2066 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2067 long time.)
2068
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002069- Issue #1580: On most platforms, use a 'short' float repr: for a
2070 finite float x, repr(x) now outputs a string based on the shortest
2071 sequence of decimal digits that rounds to x. Previous behaviour was
2072 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002073 Another minor difference is that the new repr switches to
2074 exponential notation at 1e16 instead of the previous 1e17; this
2075 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002076
2077 There's a new sys attribute sys.float_repr_style, which takes
2078 the value 'short' to indicate that we're using short float repr,
2079 and 'legacy' if the short float repr isn't available for one
2080 reason or another.
2081
2082 The float repr change involves incorporating David Gay's 'perfect
2083 rounding' code into the Python core (it's in Python/dtoa.c). As a
2084 secondary consequence, all string-to-float and float-to-string
2085 conversions (including all float formatting operations) will be
2086 correctly rounded on these platforms.
2087
2088 See issue 1580 discussions for details of platforms for which
2089 this change does not apply.
2090
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002091- Issue #5759: float() didn't call __float__ on str subclasses.
2092
Georg Brandlabc38772009-04-12 15:51:51 +00002093- The string.maketrans() function is deprecated; there is a new static method
2094 maketrans() on the bytes and bytearray classes. This removes confusion about
2095 the types string.maketrans() is supposed to work with, and mirrors the
2096 methods available on the str class.
2097
R. David Murraydc6da8a2009-04-09 22:16:43 +00002098- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

2265 untrackable objects are not tracked by the garbage collector. This can
2266 reduce the size of collections and therefore the garbage collection overhead
2267 on long-running programs, depending on their particular use of datatypes.

Lars Gustäbel42e00912009-03-22 20:34:29 +00002337- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2338 forever on incomplete input. That caused tarfile.open() to hang when used
2339 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2340 partial bzip2 compressed data.
2341
Mark Dickinson79f52032009-03-17 23:12:51 +00002342- Issue #2110: Add support for thousands separator and 'n' type
2343 specifier to Decimal.__format__
2344

2346 '>' alignment characters.
2347
Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00002348- The error detection code in FileIO.close() could fail to reflect the `errno`
2349 value, and report it as -1 instead.
2350
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00002351- Issue #5016: FileIO.seekable() could return False if the file position

2360 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002361 struct.error instead of returning b'\xff\xff\xff\xff'. The
2362 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2363 have been removed from the struct module.

2382 contained non ascii character on windows.
2383
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002384- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2385 source has already been decoded into str.
2386
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002387- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2388 rotating the object pointer by 4 bits to the right.
2389
Mark Dickinson87ec0852009-02-09 17:15:59 +00002390- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2391 it now forces its argument to double before testing for infinity.
2392
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002393- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2394 returns a non-number type.
2395
Benjamin Peterson87618552009-02-08 15:00:52 +00002396- Issue #5182: Removed memoryview.__str__.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002402
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002403- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002404 were suppressing all exceptions. These include list() and bytearray().
2405
Mark Dickinson1124e712009-01-28 21:25:58 +00002406- Issue #4707: round(x, n) now returns an integer if x is an integer.
2407 Previously it returned a float.
2408
Antoine Pitroub52ec782009-01-25 16:34:23 +00002409- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2410 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2411 evaluation loop is compiled with a new dispatch mechanism which gives
2412 speedups of up to 20%, depending on the system, on various benchmarks.
2413
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002414- Issue #4874: Most builtin decoders now reject unicode input.

2420
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002421- Issue #4838: When a module is deallocated, free the memory backing the
2422 optional module state data.
2423
Mark Dickinson8055afd2009-01-17 10:04:45 +00002424- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2425 type to (void *).
2426
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002427- Issue #4935: The overflow checking code in the expandtabs() method common
2428 to str, bytes and bytearray could be optimized away by the compiler, letting
2429 the interpreter segfault instead of raising an error.
2430
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002431- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2432 __next__ method.
2433
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002434- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2435 function no longer attempt to call the __long__ slot to convert an object
2436 to an integer. Only the __int__ and __trunc__ slots are examined.
2437
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002438- Issue #4893: Use NT threading on CE.
2439
Martin v. Löwisec59d042009-01-12 07:59:10 +00002440- Issue #4915: Port sysmodule to Windows CE.
2441
Antoine Pitrouab868312009-01-10 15:40:25 +00002442- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2443 common cases are optimized thanks to a dedicated fast path and a moderate
2444 amount of loop unrolling.
2445
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002446- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2447 collecting the oldest generation) so that allocating lots of objects without
2448 destroying them does not show quadratic performance. Based on a proposal by
2449 Martin von Löwis at
2450 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2451
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002452- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002453 having been closed (for instance, a read() call could return some
2454 previously buffered data). Patch by Dmitry Vasiliev.
2455
Antoine Pitrou05608432009-01-09 18:53:14 +00002456- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2457 flag to work properly. Furthermore, when specifying -u, the text stdout
2458 and stderr streams have line-by-line buffering enabled (the default being
2459 to buffer arbitrary chunks of data).
2460
Raymond Hettinger35631532009-01-09 03:58:09 +00002461- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2462 instead of ints (reducing its size from 4 to 8 times thereby reducing
2463 Python's overall memory).
2464
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002465- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2466 an existing .py counterpart, override the co_filename attributes of all
2467 code objects if the original filename is obsolete (which can happen if the
2468 file has been renamed, moved, or if it is accessed through different paths).
2469 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2470
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002471- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2472 one byte. Also fixes the meaning of len() so that it returns the number of
2473 items, rather than the size in bytes.
2474
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002475- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2476
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002477- Issue #4747: When the terminal does not use utf-8, executing a script with
2478 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2479
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002480- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002481 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002482
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002483- Issue #3680: Reference cycles created through a dict, set or deque iterator
2484 did not get collected.
2485
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002486- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2487 where the tp_hash and tp_dict slots are both NULL.
2488
Georg Brandlccc47b62008-12-28 11:44:14 +00002489- Issue #4759: None is now allowed as the first argument of
2490 bytearray.translate(). It was always allowed for bytes.translate().
2491
Skip Montanaro80072cb2008-12-23 03:51:14 +00002492- Added test case to ensure attempts to read from a file opened for writing
2493 fail.
2494
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002495- Issue #3106: Speedup some comparisons (str/str and int/int).

2499
Antoine Pitrou621601a2008-12-17 23:18:19 +00002500- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2501 print elapsed times, not only when some objects are uncollectable /
2502 unreachable. Original patch by Neil Schemenauer.
2503
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002504- Issue #3439: Add a bit_length method to int.
2505
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002506- Issue #2173: When getting device encoding, check that return value of
2507 nl_langinfo is not the empty string. This was causing silent build
2508 failures on OS X.
2509
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002510- Issue #4597: Fixed several opcodes that weren't always propagating
2511 exceptions.
2512
2513- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002514 context manager returns a value that cannot be converted to a bool.
2515
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002516- Issue #4445: Replace "sizeof(PyBytesObject)" with
2517 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2518 bytes instances. On a typical machine this saves 3 bytes of memory
2519 (on average) per allocation of a bytes instance.
2520
Christian Heimesa872de52008-12-05 08:26:55 +00002521- Issue #4533: File read operation was dreadfully slow due to a slowly
2522 growing read buffer. Fixed by using the same growth rate algorithm as
2523 Python 2.x.
2524
Antoine Pitrou5504e892008-12-06 21:27:53 +00002525- Issue #4509: Various issues surrounding resize of bytearray objects to
2526 which there are buffer exports (e.g. memoryview instances).
2527
Georg Brandlf9734072008-12-07 15:30:06 +00002528- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2529 method on file objects with closefd=False. The file descriptor is still
2530 kept open but the file object behaves like a closed file. The ``FileIO``
2531 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002532
Antoine Pitroubc420402008-12-07 20:14:49 +00002533- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2534 larger than 1.

2539
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002540- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2541 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2542 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2543 of using the replace error handler in PyUnicode_DecodeUTF8().
