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.

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

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

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

608 subprocess.Popen() and os._execvpe() support bytes program name. Add
609 os.supports_bytes_environ flag: True if the native OS type of the environment
610 is bytes (eg. False on Windows).
611
Lars Gustäbel1465cc22010-05-17 18:02:50 +0000612- Issue #8633: tarfile is now able to read and write archives with "raw" binary
613 pax headers as described in POSIX.1-2008.
614
Florent Xiclunac7b8e862010-05-17 17:33:07 +0000615- Issue #1285086: Speed up urllib.parse functions: quote, quote_from_bytes,
616 unquote, unquote_to_bytes.
617
Tarek Ziadéc16a85c2010-05-17 10:38:53 +0000618- Issue #8688: Distutils now recalculates MANIFEST everytime.
619
Victor Stinnerf9faaad2010-05-16 21:36:37 +0000620- Issue #8477: ssl.RAND_egd() and ssl._test_decode_cert() support str with
621 surrogates and bytes for the filename
Victor Stinner3800e1e2010-05-16 21:23:48 +0000622
Antoine Pitrou152efa22010-05-16 18:19:27 +0000623- Issue #8550: Add first class ``SSLContext`` objects to the ssl module.
624
Antoine Pitrou53b21662010-05-11 23:46:02 +0000625- Issue #8681: Make the zlib module's error messages more informative when
626 the zlib itself doesn't give any detailed explanation.
627
Mark Dickinson81fece22010-05-11 13:34:35 +0000628- The audioop module now supports sound fragments of length greater
629 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
630
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000631- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
632 class.
633
Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000634- Issue #8664: In py_compile, create __pycache__ when the compiled path is
635 given.
636
Victor Stinner449c4662010-05-08 11:10:09 +0000637- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
638 for use in the file system, environment variables or the command line.
639
Antoine Pitrou89562712010-05-07 17:04:02 +0000640- Issue #8571: Fix an internal error when compressing or decompressing a
641 chunk larger than 1GB with the zlib module's compressor and decompressor
642 objects.
643
Benjamin Peterson225168e2010-05-06 22:29:53 +0000644- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
645 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
646 file system encoding with the surrogateescape error handler (instead of
647 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000648
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000649- Issue #8573: asyncore _strerror() function might throw ValueError.
650
Victor Stinnere125f132010-05-15 21:04:43 +0000651- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
652 error messages when accessing undefined class attributes because of the cheap
653 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000654 The cheap inheritance has been deprecated.
655
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000656- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
657 Patch by Tres Seaver.
658
Victor Stinnerde629d42010-05-05 21:43:57 +0000659- Issue #8390: tarfile uses surrogateespace as the default error handler
660 (instead of replace in read mode or strict in write mode)
661
Barry Warsaw83d89982010-05-05 16:18:31 +0000662- Issue #7755: Use an unencumbered audio file for tests.
663
Ronald Oussorenac764d32010-05-05 15:32:33 +0000664- Issue #8621: uuid.uuid4() returned the same sequence of values in the

666
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000667- Issue #8567: Fix precedence of signals in Decimal module: when a
668 Decimal operation raises multiple signals and more than one of those
669 signals is trapped, the specification determines the order in which
670 the signals should be handled. In many cases this order wasn't
671 being followed, leading to the wrong Python exception being raised.
672
Antoine Pitrou6be88762010-05-03 16:48:20 +0000673- Issue #7865: The close() method of :mod:`io` objects should not swallow
674 exceptions raised by the implicit flush(). Also ensure that calling
675 close() several times is supported. Patch by Pascal Chambon.
676
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000677- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
678 gc.DEBUG_STATS.
679
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000680- Issue #8354: The siginterrupt setting is now preserved for all signals,
681 not just SIGCHLD.
682
Georg Brandl25106ce2010-05-21 21:49:47 +0000683- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000684 webbrowser.get("safari").
685
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000686- Issue #8464: tarfile no longer creates files with execute permissions set
687 when mode="w|" is used.
688
Antoine Pitroubf043492010-04-29 10:11:46 +0000689- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
690 of the Linux kernel. Patch by Yaniv Aknin.
691
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000692- Issue #8295: Added shutil.unpack_archive.
693
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000694- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
695 It should correctly return an empty response now.
696
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000697- Issue #8546: Reject None given as the buffering argument to _pyio.open.
698
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000699- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
700 Sridhar Ratnakumar.
701
R. David Murrayad78d152010-04-27 02:45:53 +0000702- Issue #6656: fix locale.format_string to handle escaped percents
703 and mappings.
704
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000705- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
706 where the method could block indefinitely if called just before the
707 event loop started running. This also fixes the occasional freezes
708 witnessed in test_httpservers.
709
Antoine Pitrou40f08742010-04-24 22:04:40 +0000710- Issue #8524: When creating an SSL socket, the timeout value of the
711 original socket wasn't retained (instead, a socket with a positive timeout
712 would be turned into a non-blocking SSL socket).
713
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000714- Issue #5103: SSL handshake would ignore the socket timeout and block
715 indefinitely if the other end didn't respond.
716
717- The do_handshake() method of SSL objects now adjusts the blocking mode of
718 the SSL structure if necessary (as other methods already do).
719
Victor Stinner13bb71c2010-04-23 21:41:56 +0000720- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
721 and bytes strings for environment keys and values
722
Victor Stinner4d078042010-04-23 19:28:32 +0000723- Issue #8467: Pure Python implementation of subprocess encodes the error
724 message using surrogatepass error handler to support surrogates in the
725 message
726

728
Sean Reifscheider13daf122010-04-23 09:29:52 +0000729- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
730 the string "python" as the *ident*. openlog() arguments are all optional
731 and keywords.
732
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000733- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
734 a non-infinite timeout. Also make that method friendlier with applications
735 wanting to continue using the socket in clear-text mode, by disabling
736 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
737
Antoine Pitrou7062db82010-04-22 13:30:10 +0000738- Issue #8496: make mailcap.lookup() always return a list, rather than an
739 iterator. Patch by Gregory Nofi.
740
Victor Stinner35466c52010-04-22 11:23:23 +0000741- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
742 collation name contains a surrogate character.
743
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000744- Issue #8484: Load all ciphers and digest algorithms when initializing
745 the _ssl extension, such that verification of some SSL certificates
746 doesn't fail because of an "unknown algorithm".
747
Tarek Ziadéfb437512010-04-20 08:57:33 +0000748- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
749
Victor Stinnere125f132010-05-15 21:04:43 +0000750- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000751 shutil.copytree.
752
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000753- Issue #4814: timeout parameter is now applied also for connections resulting
754 from PORT/EPRT commands.
755
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000756- Issue #8463: added missing reference to bztar in shutil's documentation.
757
Ronald Oussoren84151202010-04-18 20:46:11 +0000758- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
759 (as long as the user didn't specify 'automatic proxy configuration').
760
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000761- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
762 code as stated in RFC-959 at chapter 5.4.
763
Victor Stinner738446f02010-04-18 00:00:44 +0000764- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
765 surrogates.
766
Antoine Pitrou0454af92010-04-17 23:51:58 +0000767- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000768 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000769
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000770- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
771 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
772
Victor Stinner0e59cc32010-04-16 23:49:32 +0000773- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
774 the current working directory.
775
Victor Stinner5bfe1462010-04-16 13:28:05 +0000776- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
777 using backslashreplace error handler
778
Victor Stinnercfa72782010-04-16 11:45:13 +0000779- Issue #8412: os.system() now accepts bytes, bytearray and str with

Senthil Kumaranad02d232010-04-16 03:02:13 +0000782- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
783 Locke and Hans Ulrich Niedermann.
784
R. David Murrayd48739f2010-04-14 18:59:18 +0000785- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
786
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000787- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
788 module now takes an optional timeout argument in seconds. Timeout support
789 relies on the system threading library, so as to avoid a semi-busy wait
790 loop.
791
Victor Stinner485fb562010-04-13 11:07:24 +0000792- Issue #8383: pickle and pickletools use surrogatepass error handler when
793 encoding unicode as utf8 to support lone surrogates and stay compatible with
794 Python 2.x and 3.0
795
R. David Murrayb2416e52010-04-12 16:58:02 +0000796- Issue #7585: difflib context and unified diffs now place a tab between
797 filename and date, conforming to the 'standards' they were originally
798 designed to follow. This improves compatibility with patch tools.
799
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000800- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
801 character sets will now consistently use a Content-Transfer-Encoding of
802 7bit rather than sometimes being marked as 8bit.
803
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000804- Issue #8375: test_distutils now checks if the temporary directory are still
805 present before it cleans them.
806
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000807- Issue #8374: Update the internal alias table in the :mod:`locale` module
808 to cover recent locale changes and additions.
809
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000810- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
811 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
812 and `ssl.OPENSSL_VERSION_NUMBER`.
813
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000814- Add functools.total_ordering() and functools.cmp_to_key().
815
Mark Dickinson089b00c2010-04-03 15:51:03 +0000816- Issue #8257: The Decimal construct now accepts a float instance
817 directly, converting that float to a Decimal of equal value:
818
819 >>> Decimal(1.1)
820 Decimal('1.100000000000000088817841970012523233890533447265625')
821
Mark Dickinson98127c32010-04-03 11:18:52 +0000822- Issue #8294: The Fraction constructor now accepts Decimal and float
823 instances directly.
824
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000825- Issue #7279: Comparisons involving a Decimal signaling NaN now
826 signal InvalidOperation instead of returning False. (Comparisons
827 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
828 are now hashable; Decimal signaling NaNs remain unhashable.
829
830- Issue #2531: Comparison operations between floats and Decimal
831 instances now return a result based on the numeric values of the
832 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000833 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000834 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000835
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000836- Added a subtract() method to collections.Counter().
837
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000838- Issue #8233: When run as a script, py_compile.py optionally takes a single
839 argument `-` which tells it to read files to compile from stdin. Each line
840 is read on demand and the named file is compiled immediately. (Original
841 patch by Piotr Ożarowski).
842
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000843- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
844 form feed (0x0C) are now considered linebreaks, as specified in Unicode
845 Standard Annex #14. See issue #7643.
846 http://www.unicode.org/reports/tr14/
847
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000848- Comparisons using one of <, <=, >, >= between a complex instance and
849 a Fractions instance now raise TypeError instead of returning
850 True/False. This makes Fraction <=> complex comparisons consistent with
851 int <=> complex, float <=> complex, and complex <=> complex comparisons.
852
Antoine Pitrou39b35432010-03-23 00:25:54 +0000853- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
854 some methods (such as oss_mixer_device.fileno()) were not available.
855 Initial patch by Bertrand Janin.
856
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000857- Issue #8205: Remove the "Modules" directory from sys.path when Python is
858 running from the build directory (POSIX only).
859
Antoine Pitrou910bd512010-03-22 20:11:09 +0000860- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
861 didn't support chflags() (for example ZFS under FreeBSD). The error is
862 now silenced.
863
R. David Murrayca2edce2010-03-22 17:48:48 +0000864- Issue #7860: platform.uname now reports the correct 'machine' type
865 when Python is running in WOW64 mode on 64 bit Windows.
866
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000867- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
868 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
869 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000870
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000871- Issue #4282: Fix the main function of the profile module for a non-ASCII
872 script, open the file in binary mode and not in text mode with the default
873 (utf8) encoding.
874
Florent Xicluna54467e02010-03-21 12:29:50 +0000875- Issue #8179: Fix macpath.realpath() on a non-existing path.
876
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000877- Issue #8024: Update the Unicode database to 5.2.
878
Benjamin Peterson00888932010-03-18 22:37:38 +0000879- Issue #8168: py_compile now handles files with utf-8 BOMS.
880
Benjamin Peterson689a5582010-03-18 22:29:52 +0000881- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
882 detected.
883
Martin v. Löwis4b003072010-03-16 13:19:21 +0000884- Issue #6716/2: Backslash-replace error output in compilall.
885
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000886- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
887 with Tcl/Tk-8.5.
888
Matthias Klosec33b9022010-03-16 00:36:26 +0000889- Issue #8140: extend compileall to compile single files. Add -i option.
890
Matthias Klose82f60912010-03-15 13:46:04 +0000891- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
892 the locale.
893
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000894- The internals of the subprocess module on POSIX systems have been replaced
895 by an extension module (_posixsubprocess) so that the fork()+exec() can be
896 done safely without the possibility of deadlock in multithreaded applications.
897
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000898- subprocess.Popen now has restore_signals and start_new_session features.
899 The default of restore_signals=True is a new behavior compared to earlier
900 Python versions. This means that signals such as SIGPIPE are not ignored

Gregory P. Smith50467882009-11-01 18:42:17 +00001205- Issue #7246 & Issue #7208: getpass now properly flushes input before
1206 reading from stdin so that existing input does not confuse it and
1207 lead to incorrect entry or an IOError. It also properly flushes it
1208 afterwards to avoid the terminal echoing the input afterwards on
1209 OSes such as Solaris.

Brett Cannon69194272009-07-20 04:23:48 +00001341- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
1342 loaders that allow for modules to be executed. Both importlib.abc.PyLoader
1343 and PyPycLoader inherit from this class and provide implementations in
1344 relation to other methods required by the ABCs.
1345
Brett Cannon64ef00f2009-07-20 03:19:18 +00001346- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001398- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1399 10,000. Prior to this change, timezone adjustment in utctimetuple()
1400 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1401 raised in these edge cases.
1402
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001403- Issue #6641: The ``datetime.strptime`` method now supports the
1404 ``%z`` directive. When the ``%z`` directive is present in the
1405 format string, an aware ``datetime`` object is returned with
1406 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1407 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1408 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1409 without ``%z`` is discarded.
1410
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001411- Issue #5094: The ``datetime`` module now has a simple concrete class
1412 implementing ``datetime.tzinfo`` interface. Instances of the new
1413 class, ``datetime.timezone``, return fixed name and UTC offset from
1414 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1415 method always returns ``None``. A class attribute, ``utc`` contains
1416 an instance representing the UTC timezone. Original patch by Rafe
1417 Kaplan.

1421
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001422- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001423 For example, "1" or "ilib123" are now invalid formats and cause

Stefan Kraha3ac44e2010-06-08 14:00:52 +00001426- Issue #7384: If the system readline library is linked against ncurses,
1427 the curses module must be linked against ncurses as well. Otherwise it
1428 is not safe to load both the readline and curses modules in an application.
1429
Brian Curtin60853212010-05-26 17:43:50 +00001430- Issue #2810: Fix cases where the Windows registry API returns

1432
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001433- Issue #8692: Optimize math.factorial: replace the previous naive
1434 algorithm with an improved 'binary-split' algorithm that uses fewer
1435 multiplications and allows many of the multiplications to be
1436 performed using plain C integer arithmetic instead of PyLong
1437 arithmetic. Also uses a lookup table for small arguments.
1438
Mark Dickinson85eacea2010-05-10 16:27:45 +00001439- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing

1441
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001442- Issue #8644: The accuracy of td.total_seconds() has been improved (by

1444 the result is now always correctly rounded, and is equivalent to td /
1445 timedelta(seconds=1).
1446
Mark Dickinson7c186e22010-04-20 22:32:49 +00001447- Issue #2706: Allow division of a timedelta by another timedelta:

Mark Dickinsonc5935772010-04-03 15:54:36 +00001453- Issue #8300: When passing a non-integer argument to struct.pack with any
1454 integer format code, struct.pack first attempts to convert the non-integer
1455 using its __index__ method. If that method is non-existent or raises
1456 TypeError it goes on to try the __int__ method, as described below.

1707 leak-chasing test runs give sensible results. The previous method of
1708 reaping threads could return successfully while some Thread objects were
1709 still referenced. This also introduces a new private function:
1710 :func:`_thread._count()`.

1714
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001715- Issue #7055: test___all__ now greedily detects all modules which have an

1723
Brett Cannon3c273842009-07-20 00:14:29 +00001724- Fixed tests in importlib.test.source.test_abc_loader that were masking
1725 the proper exceptions that should be raised for missing or improper code
1726 object bytecode.
1727
Brett Cannonb49c70c2009-07-15 04:08:33 +00001728- Removed importlib's custom test discovery code and switched to

1920 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00002001- Issue #5914: Add new C API function PyOS_string_to_double, and
2002 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2003
Eric Smith741191f2009-05-06 13:08:15 +00002004- Issue #3382: float.__format__, complex.__format__, and %-formatting
2005 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2006 affects nan -> NAN and inf -> INF.
2007
Mark Hammond5a607a32009-05-06 08:04:54 +00002008- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2009 in all operations, including splitdrive, split, etc. splitunc() now issues
2010 a PendingDeprecation warning.
2011
Eric Smith63376222009-05-05 14:04:18 +00002012- Issue #5920: For float.__format__, change the behavior with the
2013 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2014 to be like 'g' but with at least one decimal point and with a
2015 default precision of 12. Previously, the behavior the same but with
2016 a default precision of 6. This more closely matches str(), and
2017 reduces surprises when adding alignment flags to the empty
2018 presentation type. This also affects the new complex.__format__ in
2019 the same way.
2020
Martin v. Löwis011e8422009-05-05 04:43:17 +00002021- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

2033 received a new method, detach(). detach() disconnects the underlying stream
2034 from the buffer or text IO and returns it.
2035
Mark Dickinson33841c32009-05-01 15:37:04 +00002036- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2037 floats with absolute value over 1e50. Also remove length
2038 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2039 12.34 no longer raise an exception.

Eric Smith58a42242009-04-30 01:00:33 +00002042 format(complex(1, 2./3), '.5') now produces a sensible result.
2043
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002044- Issue #5864: Fix empty format code formatting for floats so that it
2045 never gives more than the requested number of significant digits.
2046
Eric Smith6dc46f52009-04-27 20:39:49 +00002047- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

2054
Benjamin Peterson193152c2009-04-25 01:08:45 +00002055- Issue #5283: Setting __class__ in __del__ caused a segfault.
2056
Mark Dickinsonad476da2009-04-23 19:14:16 +00002057- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2058 z involves nans, infs or negative zeros.
2059
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002060- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002061
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002062- Issue #1869 (and many duplicates): make round(x, n) correctly
2063 rounded for a float x, by using the decimal <-> binary conversions
2064 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2065 consistently agrees with format(x, '.2f').
2066
Benjamin Petersonae937c02009-04-18 20:54:08 +00002067- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2068 some builtin types.
2069
Eric Smith0923d1d2009-04-16 20:16:10 +00002070- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2071
Eric Smith35e84722009-04-16 20:21:28 +00002072- Issue #5515: str.format() type 'n' combined with commas and leading
2073 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002074
2075- Implement PEP 378, Format Specifier for Thousands Separator, for
2076 floats.
2077
Mark Dickinson3370cce2009-04-17 22:40:53 +00002078- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002079 1e11, not 1e12. This avoids printing 13 significant digits in
2080 situations where only 12 of them are correct. Example problem
2081 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2082 long time.)
2083
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002084- Issue #1580: On most platforms, use a 'short' float repr: for a
2085 finite float x, repr(x) now outputs a string based on the shortest
2086 sequence of decimal digits that rounds to x. Previous behaviour was
2087 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002088 Another minor difference is that the new repr switches to
2089 exponential notation at 1e16 instead of the previous 1e17; this
2090 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002091
2092 There's a new sys attribute sys.float_repr_style, which takes
2093 the value 'short' to indicate that we're using short float repr,
2094 and 'legacy' if the short float repr isn't available for one
2095 reason or another.
2096
2097 The float repr change involves incorporating David Gay's 'perfect
2098 rounding' code into the Python core (it's in Python/dtoa.c). As a
2099 secondary consequence, all string-to-float and float-to-string
2100 conversions (including all float formatting operations) will be
2101 correctly rounded on these platforms.
2102
2103 See issue 1580 discussions for details of platforms for which
2104 this change does not apply.
2105
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002106- Issue #5759: float() didn't call __float__ on str subclasses.
2107
Georg Brandlabc38772009-04-12 15:51:51 +00002108- The string.maketrans() function is deprecated; there is a new static method
2109 maketrans() on the bytes and bytearray classes. This removes confusion about
2110 the types string.maketrans() is supposed to work with, and mirrors the
2111 methods available on the str class.
2112
R. David Murraydc6da8a2009-04-09 22:16:43 +00002113- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00002119- Issue #3739: The unicode-internal encoder now reports the number of characters

2280 untrackable objects are not tracked by the garbage collector. This can
2281 reduce the size of collections and therefore the garbage collection overhead
2282 on long-running programs, depending on their particular use of datatypes.

2351
Lars Gustäbel42e00912009-03-22 20:34:29 +00002352- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2353 forever on incomplete input. That caused tarfile.open() to hang when used
2354 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2355 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002376 struct.error instead of returning b'\xff\xff\xff\xff'. The
2377 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2378 have been removed from the struct module.

2397 contained non ascii character on windows.
2398
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002399- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2400 source has already been decoded into str.
2401

2403 rotating the object pointer by 4 bits to the right.
2404
Mark Dickinson87ec0852009-02-09 17:15:59 +00002405- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2406 it now forces its argument to double before testing for infinity.
2407
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002408- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2409 returns a non-number type.
2410
Benjamin Peterson87618552009-02-08 15:00:52 +00002411- Issue #5182: Removed memoryview.__str__.

2416 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002417
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002418- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002419 were suppressing all exceptions. These include list() and bytearray().
2420
Mark Dickinson1124e712009-01-28 21:25:58 +00002421- Issue #4707: round(x, n) now returns an integer if x is an integer.
2422 Previously it returned a float.
2423
Antoine Pitroub52ec782009-01-25 16:34:23 +00002424- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2425 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2426 evaluation loop is compiled with a new dispatch mechanism which gives
2427 speedups of up to 20%, depending on the system, on various benchmarks.
2428
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002429- Issue #4874: Most builtin decoders now reject unicode input.

2435
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002436- Issue #4838: When a module is deallocated, free the memory backing the
2437 optional module state data.
2438
Mark Dickinson8055afd2009-01-17 10:04:45 +00002439- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2440 type to (void *).
2441
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002442- Issue #4935: The overflow checking code in the expandtabs() method common
2443 to str, bytes and bytearray could be optimized away by the compiler, letting
2444 the interpreter segfault instead of raising an error.
2445
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002446- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2447 __next__ method.
2448
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002449- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2450 function no longer attempt to call the __long__ slot to convert an object
2451 to an integer. Only the __int__ and __trunc__ slots are examined.
2452
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002453- Issue #4893: Use NT threading on CE.
2454
Martin v. Löwisec59d042009-01-12 07:59:10 +00002455- Issue #4915: Port sysmodule to Windows CE.
2456
Antoine Pitrouab868312009-01-10 15:40:25 +00002457- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2458 common cases are optimized thanks to a dedicated fast path and a moderate
2459 amount of loop unrolling.
2460
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002461- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2462 collecting the oldest generation) so that allocating lots of objects without
2463 destroying them does not show quadratic performance. Based on a proposal by
2464 Martin von Löwis at
2465 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2466
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002467- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002468 having been closed (for instance, a read() call could return some
2469 previously buffered data). Patch by Dmitry Vasiliev.
2470
Antoine Pitrou05608432009-01-09 18:53:14 +00002471- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2472 flag to work properly. Furthermore, when specifying -u, the text stdout
2473 and stderr streams have line-by-line buffering enabled (the default being
2474 to buffer arbitrary chunks of data).
2475
Raymond Hettinger35631532009-01-09 03:58:09 +00002476- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2477 instead of ints (reducing its size from 4 to 8 times thereby reducing
2478 Python's overall memory).
2479
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002480- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2481 an existing .py counterpart, override the co_filename attributes of all
2482 code objects if the original filename is obsolete (which can happen if the
2483 file has been renamed, moved, or if it is accessed through different paths).
2484 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2485
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002486- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2487 one byte. Also fixes the meaning of len() so that it returns the number of
2488 items, rather than the size in bytes.
2489
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002490- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2491
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002492- Issue #4747: When the terminal does not use utf-8, executing a script with
2493 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2494
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002495- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002496 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002497
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002498- Issue #3680: Reference cycles created through a dict, set or deque iterator
2499 did not get collected.
2500
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002501- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2502 where the tp_hash and tp_dict slots are both NULL.
2503
Georg Brandlccc47b62008-12-28 11:44:14 +00002504- Issue #4759: None is now allowed as the first argument of
2505 bytearray.translate(). It was always allowed for bytes.translate().
2506
Skip Montanaro80072cb2008-12-23 03:51:14 +00002507- Added test case to ensure attempts to read from a file opened for writing
2508 fail.
2509
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002510- Issue #3106: Speedup some comparisons (str/str and int/int).

2513 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2514
Antoine Pitrou621601a2008-12-17 23:18:19 +00002515- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2516 print elapsed times, not only when some objects are uncollectable /
2517 unreachable. Original patch by Neil Schemenauer.
2518
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002519- Issue #3439: Add a bit_length method to int.
2520
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002521- Issue #2173: When getting device encoding, check that return value of
2522 nl_langinfo is not the empty string. This was causing silent build
2523 failures on OS X.
2524
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002525- Issue #4597: Fixed several opcodes that weren't always propagating
2526 exceptions.
2527
2528- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002529 context manager returns a value that cannot be converted to a bool.
2530
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002531- Issue #4445: Replace "sizeof(PyBytesObject)" with
2532 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2533 bytes instances. On a typical machine this saves 3 bytes of memory
2534 (on average) per allocation of a bytes instance.
2535
Christian Heimesa872de52008-12-05 08:26:55 +00002536- Issue #4533: File read operation was dreadfully slow due to a slowly
2537 growing read buffer. Fixed by using the same growth rate algorithm as
2538 Python 2.x.
2539
Antoine Pitrou5504e892008-12-06 21:27:53 +00002540- Issue #4509: Various issues surrounding resize of bytearray objects to
2541 which there are buffer exports (e.g. memoryview instances).
2542
Georg Brandlf9734072008-12-07 15:30:06 +00002543- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2544 method on file objects with closefd=False. The file descriptor is still
2545 kept open but the file object behaves like a closed file. The ``FileIO``
2546 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002547
Antoine Pitroubc420402008-12-07 20:14:49 +00002548- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2554
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002555- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2556 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2557 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2558 of using the replace error handler in PyUnicode_DecodeUTF8().
