11
12Core and Builtins
13-----------------
14
Mark Dickinson50b79a82010-06-30 11:13:36 +000015- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real
16 part -0.0 rather than 0.0. So "-7j" is now exactly equivalent to
17 "-(7j)".
18
Benjamin Peterson88968ad2010-06-25 19:30:21 +000019- Be more specific in error messages about positional arguments.
20
Victor Stinner4aae1eb2010-06-24 22:08:25 +000021- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
22 objects, as described in the documentation.
23
Victor Stinner0fe25a42010-06-17 23:08:50 +000024- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000025 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
26 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000027
Mark Dickinsond35a32e2010-06-17 12:33:22 +000028- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
29 compilation code dealing with unary minus applied to a constant.
30 The removed code was mutating the ST, causing a second compilation
31 to fail.
32
Victor Stinner554f3f02010-06-16 23:33:54 +000033- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
34 mode raises unicode errors. The encoder only supports "strict" and "replace"
35 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000036 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000037
Victor Stinner25e8ec42010-06-25 00:02:38 +000038- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
39 "w*" format instead. Add tests for "w*" format.
40
Victor Stinner06e49dd2010-06-13 18:21:50 +000041- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
42 formats if the string contains a null byte/character. Write unit tests for
43 string formats.
44
Nick Coghlan5e76e942010-06-12 13:42:46 +000045- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
46 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
47 location of the raised exception.
48
Victor Stinner313a1202010-06-11 23:56:51 +000049- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
50 filenames and enable os.fsencode().
51
Benjamin Peterson285a6892010-06-22 19:21:52 +000052- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
53
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000054- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
55 the interpreter with characters outside the Basic Multilingual Plane
56 (higher than 0x10000).
57
Mark Dickinsonc7301312010-06-10 16:05:10 +000058- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
59 raise TypeError instead of giving a DeprecationWarning when a float
60 is parsed using the 'L' code (for long long). (All other integer
61 codes already raise TypeError in this case.)
62
Victor Stinner600d3be2010-06-10 12:00:55 +000063- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
64 enable shortcuts for upper case encoding name. Add also a shortcut for
65 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
66
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000067- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
68 doesn't support "char buffer" anymore in Python3.
69
70- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
71 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
72 like bytearray.
73
Victor Stinner33109a12010-05-28 21:55:10 +000074- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
75 used anymore and it was never documented.
76
Benjamin Peterson95304522010-06-08 14:57:22 +000077- In the str.format(), raise a ValueError when indexes to arguments are too
78 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000079
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000080- Issue #2844: Make int('42', n) consistently raise ValueError for
81 invalid integers n (including n = -909).
82
Mark Dickinsondc787d22010-05-23 13:33:13 +000083- Issue #8188: Introduce a new scheme for computing hashes of numbers
84 (instances of int, float, complex, decimal.Decimal and
85 fractions.Fraction) that makes it easy to maintain the invariant
86 that hash(x) == hash(y) whenever x and y have equal value.
87
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000088- Issue #8748: Fix two issues with comparisons between complex and integer
89 objects. (1) The comparison could incorrectly return True in some cases
90 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
91 (2) The comparison raised an OverflowError for large integers, leading
92 to unpredictable exceptions when combining integers and complex objects
93 in sets or dicts.
94
Victor Stinner7d79b8b2010-05-19 20:40:50 +000095- Issue #8766: Initialize _warnings module before importing the first module.
96 Fix a crash if an empty directory called "encodings" exists in sys.path.
97
Victor Stinner9ca9c252010-05-19 16:53:30 +000098- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
99 encoding and surrogateespace error handler instead of the locale encoding to
100 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
101
Victor Stinner372ac5e2010-05-17 01:26:01 +0000102- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
103 (instead of strict) error handler to escape surrogates
104
Victor Stinnerae6265f2010-05-15 16:27:27 +0000105- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
106 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000107 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
108 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000109
Victor Stinner59e62db2010-05-15 13:14:32 +0000110- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
111 error handler, not only the default error handler (strict)
112
Victor Stinnerb744ba12010-05-15 12:27:16 +0000113- Issue #8610: Load file system codec at startup, and display a fatal error on
114 failure. Set the file system encoding to utf-8 (instead of None) if getting
115 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
116
Victor Stinner0964ee12010-04-30 16:48:45 +0000117- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
118 PyUnicode_FromString() to support surrogates in the filename and use the
119 right encoding
120
Georg Brandl8569e582010-05-19 20:57:08 +0000121- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
122
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000123- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
124
Benjamin Petersonfb886362010-04-24 18:21:17 +0000125- Issue #8419: Prevent the dict constructor from accepting non-string keyword
126 arguments.
127
Victor Stinner14284c22010-04-23 12:02:30 +0000128- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
129 indirectly Python signal handlers anymore because mywrite() ignores
130 exceptions (KeyboardInterrupt)
131
Victor Stinner31be90b2010-04-22 19:38:16 +0000132- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
133 unicode string (eg. backslashreplace)
134
Victor Stinnerdcb24032010-04-22 12:08:36 +0000135- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
136 you have to convert your bytearray filenames to bytes
137
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000138- Issue #7332: Remove the 16KB stack-based buffer in
139 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
140 benefit compared to the dynamic memory allocation fallback. Patch by
141 Charles-François Natali.
142
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000143- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
144 passed to bytes or bytearray.
145
Philip Jenvey0805ca32010-04-07 04:04:10 +0000146- Issue #7301: Add environment variable $PYTHONWARNINGS.
147
Benjamin Petersond856ab62010-04-06 21:55:16 +0000148- Issue #8329: Don't return the same lists from select.select when no fds are
149 changed.
150
Mark Dickinson3318d292010-04-06 16:53:17 +0000151- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
152 on 64-bit machines. The shift count for either left or right shift is
153 permitted to be up to sys.maxsize.
154
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000155- Ensure that tokenization of identifiers is not affected by locale.

162 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000163
Victor Stinner120c2122010-03-25 00:30:28 +0000164- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
165 is unknown
166

168
Mark Dickinsond59b4162010-03-13 11:34:40 +0000169- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
170 PyMemberDefs could produce an internal error; raise TypeError instead.
171
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000172- Issue #7845: Rich comparison methods on the complex type now return
173 NotImplemented rather than raising a TypeError when comparing with an
174 incompatible type; this allows user-defined classes to implement their own
175 comparisons with complex.
176
Victor Stinner52f6dd72010-03-12 14:45:56 +0000177- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
178 (SIGINT). If an error occurs while importing the site module, the error is
179 printed and Python exits. Initialize the GIL before importing the site
180 module.
181
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000182- Issue #7173: Generator finalization could invalidate sys.exc_info().

208 deprecations.
209
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000210- Issue #7385: Fix a crash in `MemoryView_FromObject` when
211 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
212
Mark Dickinsonbc099642010-01-29 17:27:24 +0000213- Issue #7788: Fix an interpreter crash produced by deleting a list
214 slice with very large step value.
215
Eric Smithf7bb5782010-01-27 00:44:57 +0000216- Issue #7766: Change sys.getwindowsversion() return value to a named
217 tuple and add the additional members returned in an OSVERSIONINFOEX
218 structure. The new members are service_pack_major, service_pack_minor,
219 suite_mask, and product_type.
220
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000221- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
222 could crash in many places because of the PyByteArray_AS_STRING() macro
223 returning NULL. The macro now returns a statically allocated empty
224 string instead.
225
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000226- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
227 where the right hand operand is a set of constants, by turning the set into
228 a frozenset and pre-building it as a constant. The comparison operation
229 is made against the constant instead of building a new set each time it is
230 executed (a similar optimization already existed which turned a list of
231 constants into a pre-built tuple). Patch and additional tests by Dave
232 Malcolm.
233
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000234- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
235 methods of bytes, bytearray and unicode objects by using a common
236 implementation based on stringlib's fast search. Patch by Florent Xicluna.

239 alpha 2, including: (1) a serious 'wrong output' bug that could
240 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
241 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000242 strings corresponding to subnormal values, (3) a memory leak for
243 some values large enough to cause overflow, and (4) a number of
244 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000245
Benjamin Petersonaea44282010-01-04 01:10:28 +0000246- The __complex__ method is now looked up on the class of instances to make it
247 consistent with other special methods.

256 negative zero) in ** operator. The behaviour now conforms to that
257 described in C99 Annex F.
258
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000259- Issue #1811: improve accuracy and cross-platform consistency for
260 true division of integers: the result of a/b is now correctly
261 rounded for ints a and b (at least on IEEE 754 platforms), and in
262 particular does not depend on the internal representation of an int.
263
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000264- Issue #6834: replace the implementation for the 'python' and 'pythonw'
265 executables on OSX.
266
267 These executables now work properly with the arch(1) command:
268 ``arch -ppc python`` will start a universal binary version of python
269 in PPC mode (unlike previous releases).
270
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000271- Issue #7466: segmentation fault when the garbage collector is called
272 in the middle of populating a tuple. Patch by Florent Xicluna.
273
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +0000274- Issue #7419: setlocale() could crash the interpreter on Windows when called
275 with invalid values.
276
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000277- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
278 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
279
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000280- Issue #7085: Fix crash when importing some extensions in a thread

286 implement the relevant rich comparison methods.
287
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000288- Issue #7298: fixes for range and reversed(range(...)). Iteration
289 over range(a, b, c) incorrectly gave an empty iterator when a, b and
290 c fit in C long but the length of the range did not. Also fix
291 several cases where reversed(range(a, b, c)) gave wrong results, and
292 fix a refleak for reversed(range(a, b, c)) with large arguments.
293
Raymond Hettingerfc438512009-11-01 20:55:33 +0000294- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Benjamin Petersone87c0fc2010-05-08 19:52:49 +0000608- Issue #8664: In py_compile, create __pycache__ when the compiled path is
609 given.
610
Victor Stinner449c4662010-05-08 11:10:09 +0000611- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
612 for use in the file system, environment variables or the command line.
613
Antoine Pitrou89562712010-05-07 17:04:02 +0000614- Issue #8571: Fix an internal error when compressing or decompressing a
615 chunk larger than 1GB with the zlib module's compressor and decompressor
616 objects.
617
Benjamin Peterson225168e2010-05-06 22:29:53 +0000618- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
619 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
620 file system encoding with the surrogateescape error handler (instead of
621 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.
Victor Stinner84ae1182010-05-06 22:05:07 +0000622
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000623- Issue #8573: asyncore _strerror() function might throw ValueError.
624
Victor Stinnere125f132010-05-15 21:04:43 +0000625- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
626 error messages when accessing undefined class attributes because of the cheap
627 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000628 The cheap inheritance has been deprecated.
629
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000630- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
631 Patch by Tres Seaver.
632
Victor Stinnerde629d42010-05-05 21:43:57 +0000633- Issue #8390: tarfile uses surrogateespace as the default error handler
634 (instead of replace in read mode or strict in write mode)
635
Barry Warsaw83d89982010-05-05 16:18:31 +0000636- Issue #7755: Use an unencumbered audio file for tests.
637
Ronald Oussorenac764d32010-05-05 15:32:33 +0000638- Issue #8621: uuid.uuid4() returned the same sequence of values in the
639 parent and any children created using ``os.fork`` on MacOS X 10.6.
640
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000641- Issue #8567: Fix precedence of signals in Decimal module: when a
642 Decimal operation raises multiple signals and more than one of those
643 signals is trapped, the specification determines the order in which
644 the signals should be handled. In many cases this order wasn't
645 being followed, leading to the wrong Python exception being raised.
646
Antoine Pitrou6be88762010-05-03 16:48:20 +0000647- Issue #7865: The close() method of :mod:`io` objects should not swallow
648 exceptions raised by the implicit flush(). Also ensure that calling
649 close() several times is supported. Patch by Pascal Chambon.
650
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000651- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
652 gc.DEBUG_STATS.
653
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000654- Issue #8354: The siginterrupt setting is now preserved for all signals,
655 not just SIGCHLD.
656
Georg Brandl25106ce2010-05-21 21:49:47 +0000657- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000658 webbrowser.get("safari").
659
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000660- Issue #8464: tarfile no longer creates files with execute permissions set
661 when mode="w|" is used.
662
Antoine Pitroubf043492010-04-29 10:11:46 +0000663- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
664 of the Linux kernel. Patch by Yaniv Aknin.
665
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000666- Issue #8295: Added shutil.unpack_archive.
667
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000668- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
669 It should correctly return an empty response now.
670
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000671- Issue #8546: Reject None given as the buffering argument to _pyio.open.
672
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000673- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
674 Sridhar Ratnakumar.
675
R. David Murrayad78d152010-04-27 02:45:53 +0000676- Issue #6656: fix locale.format_string to handle escaped percents
677 and mappings.
678
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000679- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
680 where the method could block indefinitely if called just before the
681 event loop started running. This also fixes the occasional freezes
682 witnessed in test_httpservers.
683
Antoine Pitrou40f08742010-04-24 22:04:40 +0000684- Issue #8524: When creating an SSL socket, the timeout value of the
685 original socket wasn't retained (instead, a socket with a positive timeout
686 would be turned into a non-blocking SSL socket).
687
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000688- Issue #5103: SSL handshake would ignore the socket timeout and block
689 indefinitely if the other end didn't respond.
690
691- The do_handshake() method of SSL objects now adjusts the blocking mode of
692 the SSL structure if necessary (as other methods already do).
693
Victor Stinner13bb71c2010-04-23 21:41:56 +0000694- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
695 and bytes strings for environment keys and values
696
Victor Stinner4d078042010-04-23 19:28:32 +0000697- Issue #8467: Pure Python implementation of subprocess encodes the error
698 message using surrogatepass error handler to support surrogates in the
699 message
700
Victor Stinner349fd522010-04-23 10:56:17 +0000701- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
702
Sean Reifscheider13daf122010-04-23 09:29:52 +0000703- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
704 the string "python" as the *ident*. openlog() arguments are all optional
705 and keywords.
706
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000707- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
708 a non-infinite timeout. Also make that method friendlier with applications
709 wanting to continue using the socket in clear-text mode, by disabling
710 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
711
Antoine Pitrou7062db82010-04-22 13:30:10 +0000712- Issue #8496: make mailcap.lookup() always return a list, rather than an
713 iterator. Patch by Gregory Nofi.
714
Victor Stinner35466c52010-04-22 11:23:23 +0000715- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
716 collation name contains a surrogate character.
717
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000718- Issue #8484: Load all ciphers and digest algorithms when initializing
719 the _ssl extension, such that verification of some SSL certificates
720 doesn't fail because of an "unknown algorithm".
721
Tarek Ziadéfb437512010-04-20 08:57:33 +0000722- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
723
Victor Stinnere125f132010-05-15 21:04:43 +0000724- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000725 shutil.copytree.
726
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000727- Issue #4814: timeout parameter is now applied also for connections resulting
728 from PORT/EPRT commands.
729
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000730- Issue #8463: added missing reference to bztar in shutil's documentation.
731
Ronald Oussoren84151202010-04-18 20:46:11 +0000732- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
733 (as long as the user didn't specify 'automatic proxy configuration').
734
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000735- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
736 code as stated in RFC-959 at chapter 5.4.
737
Victor Stinner738446f02010-04-18 00:00:44 +0000738- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
739 surrogates.
740
Antoine Pitrou0454af92010-04-17 23:51:58 +0000741- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000742 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000743
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000744- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
745 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
746
Victor Stinner0e59cc32010-04-16 23:49:32 +0000747- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
748 the current working directory.
749
Victor Stinner5bfe1462010-04-16 13:28:05 +0000750- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
751 using backslashreplace error handler
752
Victor Stinnercfa72782010-04-16 11:45:13 +0000753- Issue #8412: os.system() now accepts bytes, bytearray and str with
754 surrogates.
755
Senthil Kumaranad02d232010-04-16 03:02:13 +0000756- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
757 Locke and Hans Ulrich Niedermann.
758
R. David Murrayd48739f2010-04-14 18:59:18 +0000759- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
760
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000761- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
762 module now takes an optional timeout argument in seconds. Timeout support
763 relies on the system threading library, so as to avoid a semi-busy wait
764 loop.
765
Victor Stinner485fb562010-04-13 11:07:24 +0000766- Issue #8383: pickle and pickletools use surrogatepass error handler when
767 encoding unicode as utf8 to support lone surrogates and stay compatible with
768 Python 2.x and 3.0
769
R. David Murrayb2416e52010-04-12 16:58:02 +0000770- Issue #7585: difflib context and unified diffs now place a tab between
771 filename and date, conforming to the 'standards' they were originally
772 designed to follow. This improves compatibility with patch tools.
773
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000774- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
775 character sets will now consistently use a Content-Transfer-Encoding of
776 7bit rather than sometimes being marked as 8bit.
777
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000778- Issue #8375: test_distutils now checks if the temporary directory are still
779 present before it cleans them.
780
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000781- Issue #8374: Update the internal alias table in the :mod:`locale` module
782 to cover recent locale changes and additions.
783
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000784- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
785 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
786 and `ssl.OPENSSL_VERSION_NUMBER`.
787
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000788- Add functools.total_ordering() and functools.cmp_to_key().
789
Mark Dickinson089b00c2010-04-03 15:51:03 +0000790- Issue #8257: The Decimal construct now accepts a float instance
791 directly, converting that float to a Decimal of equal value:
792
793 >>> Decimal(1.1)
794 Decimal('1.100000000000000088817841970012523233890533447265625')
795
Mark Dickinson98127c32010-04-03 11:18:52 +0000796- Issue #8294: The Fraction constructor now accepts Decimal and float
797 instances directly.
798
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000799- Issue #7279: Comparisons involving a Decimal signaling NaN now
800 signal InvalidOperation instead of returning False. (Comparisons
801 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
802 are now hashable; Decimal signaling NaNs remain unhashable.
803
804- Issue #2531: Comparison operations between floats and Decimal
805 instances now return a result based on the numeric values of the
806 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000807 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000808 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000809
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000810- Added a subtract() method to collections.Counter().
811
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000812- Issue #8233: When run as a script, py_compile.py optionally takes a single
813 argument `-` which tells it to read files to compile from stdin. Each line
814 is read on demand and the named file is compiled immediately. (Original
815 patch by Piotr Ożarowski).
816
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000817- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
818 form feed (0x0C) are now considered linebreaks, as specified in Unicode
819 Standard Annex #14. See issue #7643.
820 http://www.unicode.org/reports/tr14/
821
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000822- Comparisons using one of <, <=, >, >= between a complex instance and
823 a Fractions instance now raise TypeError instead of returning
824 True/False. This makes Fraction <=> complex comparisons consistent with
825 int <=> complex, float <=> complex, and complex <=> complex comparisons.
826
Antoine Pitrou39b35432010-03-23 00:25:54 +0000827- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
828 some methods (such as oss_mixer_device.fileno()) were not available.
829 Initial patch by Bertrand Janin.
830
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000831- Issue #8205: Remove the "Modules" directory from sys.path when Python is
832 running from the build directory (POSIX only).
833
Antoine Pitrou910bd512010-03-22 20:11:09 +0000834- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
835 didn't support chflags() (for example ZFS under FreeBSD). The error is
836 now silenced.
837
R. David Murrayca2edce2010-03-22 17:48:48 +0000838- Issue #7860: platform.uname now reports the correct 'machine' type
839 when Python is running in WOW64 mode on 64 bit Windows.
840
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000841- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
842 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
843 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000844
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000845- Issue #4282: Fix the main function of the profile module for a non-ASCII
846 script, open the file in binary mode and not in text mode with the default
847 (utf8) encoding.
848
Florent Xicluna54467e02010-03-21 12:29:50 +0000849- Issue #8179: Fix macpath.realpath() on a non-existing path.
850
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000851- Issue #8024: Update the Unicode database to 5.2.
852
Benjamin Peterson00888932010-03-18 22:37:38 +0000853- Issue #8168: py_compile now handles files with utf-8 BOMS.
854
Benjamin Peterson689a5582010-03-18 22:29:52 +0000855- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
856 detected.
857
Martin v. Löwis4b003072010-03-16 13:19:21 +0000858- Issue #6716/2: Backslash-replace error output in compilall.
859
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000860- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
861 with Tcl/Tk-8.5.
862
Matthias Klosec33b9022010-03-16 00:36:26 +0000863- Issue #8140: extend compileall to compile single files. Add -i option.
864
Matthias Klose82f60912010-03-15 13:46:04 +0000865- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
866 the locale.
867
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000868- The internals of the subprocess module on POSIX systems have been replaced
869 by an extension module (_posixsubprocess) so that the fork()+exec() can be
870 done safely without the possibility of deadlock in multithreaded applications.
871
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000872- subprocess.Popen now has restore_signals and start_new_session features.
873 The default of restore_signals=True is a new behavior compared to earlier
874 Python versions. This means that signals such as SIGPIPE are not ignored
875 by default in subprocesses launched by Python (Issue #1652).
876
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000877- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
878 cElementTree module is updated too.
879
Victor Stinnerb33062c2010-03-12 14:27:16 +0000880- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
881 an non existent program name and Python is unable to retrieve the real
882 program name
883
Florent Xiclunaa4707382010-03-11 00:05:17 +0000884- Issue #7880: Fix sysconfig when the python executable is a symbolic link.
885
Ezio Melottib92ed7c2010-03-06 15:24:08 +0000886- Issue #6509: fix re.sub to work properly when the pattern, the string, and
887 the replacement were all bytes. Patch by Antoine Pitrou.
888
Gerhard Häringf9cee222010-03-05 15:20:03 +0000889- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
890 bugs and allows loading SQLite extensions from shared libraries.
891
Ezio Melottida227042010-03-14 11:51:00 +0000892- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public
893 Review Issue #29 (http://unicode.org/review/pr-29.html).
Victor Stinner7ed9c4c2010-03-04 12:14:57 +0000894
Victor Stinnercee3ae82010-03-04 00:29:24 +0000895- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
896 reset also the pointer to the current pointer context.
897
Lars Gustäbel01385812010-03-03 12:08:54 +0000898- Issue #7232: Add support for the context manager protocol to the TarFile
899 class.
900
Barry Warsawb1938262010-03-01 21:53:00 +0000901- Issue #7250: Fix info leak of os.environ across multi-run uses of
902 wsgiref.handlers.CGIHandler.

Nick Coghlan260bd3e2009-11-16 06:49:25 +00001135- Issue #6816: runpy now provides a run_path function that allows Python code
1136 to execute file paths that refer to source or compiled Python files as well
1137 as zipfiles, directories and other valid sys.path entries that contain a
1138 __main__.py file. This allows applications that run other Python scripts to
1139 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001158 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001159 recursive locks as fast as regular non-recursive locks (previously,
1160 they were slower by 10x to 15x).

1180 reading from stdin so that existing input does not confuse it and

1182 afterwards to avoid the terminal echoing the input afterwards on
1183 OSes such as Solaris.

1318 relation to other methods required by the ABCs.
1319
Brett Cannon64ef00f2009-07-20 03:19:18 +00001320- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001369- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1370 10,000. Prior to this change, timezone adjustment in utctimetuple()
1371 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1372 raised in these edge cases.
1373
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001374- Issue #6641: The ``datetime.strptime`` method now supports the
1375 ``%z`` directive. When the ``%z`` directive is present in the
1376 format string, an aware ``datetime`` object is returned with
1377 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1378 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1379 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1380 without ``%z`` is discarded.
1381
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001382- Issue #5094: The ``datetime`` module now has a simple concrete class
1383 implementing ``datetime.tzinfo`` interface. Instances of the new
1384 class, ``datetime.timezone``, return fixed name and UTC offset from
1385 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1386 method always returns ``None``. A class attribute, ``utc`` contains
1387 an instance representing the UTC timezone. Original patch by Rafe
1388 Kaplan.
1389
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001390- Issue #8973: Add __all__ to struct module; this ensures that

1392
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001393- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001394 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001395 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00001396
Stefan Kraha3ac44e2010-06-08 14:00:52 +00001397- Issue #7384: If the system readline library is linked against ncurses,
1398 the curses module must be linked against ncurses as well. Otherwise it
1399 is not safe to load both the readline and curses modules in an application.
1400
Brian Curtin60853212010-05-26 17:43:50 +00001401- Issue #2810: Fix cases where the Windows registry API returns

1403
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001404- Issue #8692: Optimize math.factorial: replace the previous naive
1405 algorithm with an improved 'binary-split' algorithm that uses fewer
1406 multiplications and allows many of the multiplications to be
1407 performed using plain C integer arithmetic instead of PyLong
1408 arithmetic. Also uses a lookup table for small arguments.
1409
Mark Dickinson85eacea2010-05-10 16:27:45 +00001410- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1411 overflow checks in the audioop module.
1412
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001413- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1414 calculating with integer arithmetic instead of float arithmetic internally):
1415 the result is now always correctly rounded, and is equivalent to td /
1416 timedelta(seconds=1).
1417
Mark Dickinson7c186e22010-04-20 22:32:49 +00001418- Issue #2706: Allow division of a timedelta by another timedelta:

1420 and divmod(timedelta, timedelta) are all supported.
1421
Victor Stinnerfebecd82010-04-16 12:07:30 +00001422- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
1423
Mark Dickinsonc5935772010-04-03 15:54:36 +00001424- Issue #8300: When passing a non-integer argument to struct.pack with any
1425 integer format code, struct.pack first attempts to convert the non-integer
1426 using its __index__ method. If that method is non-existent or raises
1427 TypeError it goes on to try the __int__ method, as described below.
1428

1678 leak-chasing test runs give sensible results. The previous method of
1679 reaping threads could return successfully while some Thread objects were
1680 still referenced. This also introduces a new private function:
1681 :func:`_thread._count()`.
1682
R. David Murray27144602009-10-19 15:26:16 +00001683- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1684 longer runs the risk of causing the worker thread to fail.
1685
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001686- Issue #7055: test___all__ now greedily detects all modules which have an
1687 __all__ attribute, rather than using a hardcoded and incomplete list.

1691 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001692
Mark Dickinson2e304402009-10-04 18:43:54 +00001693- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1694
Brett Cannon3c273842009-07-20 00:14:29 +00001695- Fixed tests in importlib.test.source.test_abc_loader that were masking
1696 the proper exceptions that should be raised for missing or improper code
1697 object bytecode.
1698
Brett Cannonb49c70c2009-07-15 04:08:33 +00001699- Removed importlib's custom test discovery code and switched to

Antoine Pitrou61f77b52009-05-24 15:46:13 +00001890- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1891 than an int, which makes some operations possible under 64-bit Linux (e.g.
1892 DN_MULTISHOT with F_NOTIFY).

Mark Dickinson865e01a2009-05-07 16:37:01 +00001972- Issue #5914: Add new C API function PyOS_string_to_double, and
1973 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1974
Eric Smith741191f2009-05-06 13:08:15 +00001975- Issue #3382: float.__format__, complex.__format__, and %-formatting
1976 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1977 affects nan -> NAN and inf -> INF.
1978
Mark Hammond5a607a32009-05-06 08:04:54 +00001979- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1980 in all operations, including splitdrive, split, etc. splitunc() now issues
1981 a PendingDeprecation warning.
1982
Eric Smith63376222009-05-05 14:04:18 +00001983- Issue #5920: For float.__format__, change the behavior with the
1984 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1985 to be like 'g' but with at least one decimal point and with a
1986 default precision of 12. Previously, the behavior the same but with
1987 a default precision of 6. This more closely matches str(), and
1988 reduces surprises when adding alignment flags to the empty
1989 presentation type. This also affects the new complex.__format__ in
1990 the same way.
1991
Martin v. Löwis011e8422009-05-05 04:43:17 +00001992- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

2000
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002001- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00002003- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2004 received a new method, detach(). detach() disconnects the underlying stream
2005 from the buffer or text IO and returns it.
2006
Mark Dickinson33841c32009-05-01 15:37:04 +00002007- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2008 floats with absolute value over 1e50. Also remove length
2009 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %

2016 never gives more than the requested number of significant digits.
2017
Eric Smith6dc46f52009-04-27 20:39:49 +00002018- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsone6a076d2009-04-18 11:48:33 +00002033- Issue #1869 (and many duplicates): make round(x, n) correctly
2034 rounded for a float x, by using the decimal <-> binary conversions
2035 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2036 consistently agrees with format(x, '.2f').
2037
Benjamin Petersonae937c02009-04-18 20:54:08 +00002038- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

Eric Smith35e84722009-04-16 20:21:28 +00002043- Issue #5515: str.format() type 'n' combined with commas and leading
2044 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002045
2046- Implement PEP 378, Format Specifier for Thousands Separator, for
2047 floats.
2048
Mark Dickinson3370cce2009-04-17 22:40:53 +00002049- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002050 1e11, not 1e12. This avoids printing 13 significant digits in
2051 situations where only 12 of them are correct. Example problem
2052 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2053 long time.)
2054
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002055- Issue #1580: On most platforms, use a 'short' float repr: for a
2056 finite float x, repr(x) now outputs a string based on the shortest
2057 sequence of decimal digits that rounds to x. Previous behaviour was
2058 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002059 Another minor difference is that the new repr switches to
2060 exponential notation at 1e16 instead of the previous 1e17; this
2061 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002062
2063 There's a new sys attribute sys.float_repr_style, which takes
2064 the value 'short' to indicate that we're using short float repr,
2065 and 'legacy' if the short float repr isn't available for one
2066 reason or another.
2067
2068 The float repr change involves incorporating David Gay's 'perfect
2069 rounding' code into the Python core (it's in Python/dtoa.c). As a
2070 secondary consequence, all string-to-float and float-to-string
2071 conversions (including all float formatting operations) will be
2072 correctly rounded on these platforms.
2073
2074 See issue 1580 discussions for details of platforms for which
2075 this change does not apply.
2076
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002077- Issue #5759: float() didn't call __float__ on str subclasses.
2078
Georg Brandlabc38772009-04-12 15:51:51 +00002079- The string.maketrans() function is deprecated; there is a new static method
2080 maketrans() on the bytes and bytearray classes. This removes confusion about
2081 the types string.maketrans() is supposed to work with, and mirrors the
2082 methods available on the str class.
2083
R. David Murraydc6da8a2009-04-09 22:16:43 +00002084- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

Walter Dörwald8dc33d52009-05-06 14:41:26 +00002090- Issue #3739: The unicode-internal encoder now reports the number of characters

2348 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2349 have been removed from the struct module.

2372
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002373- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2374 rotating the object pointer by 4 bits to the right.
2375
Mark Dickinson87ec0852009-02-09 17:15:59 +00002376- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2377 it now forces its argument to double before testing for infinity.
2378
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002379- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002388
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002389- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002390 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002392- Issue #4707: round(x, n) now returns an integer if x is an integer.
2393 Previously it returned a float.
2394
Antoine Pitroub52ec782009-01-25 16:34:23 +00002395- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2396 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2397 evaluation loop is compiled with a new dispatch mechanism which gives
2398 speedups of up to 20%, depending on the system, on various benchmarks.
2399
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002400- Issue #4874: Most builtin decoders now reject unicode input.

2406
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002407- Issue #4838: When a module is deallocated, free the memory backing the
2408 optional module state data.
2409
Mark Dickinson8055afd2009-01-17 10:04:45 +00002410- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2411 type to (void *).
2412
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002413- Issue #4935: The overflow checking code in the expandtabs() method common
2414 to str, bytes and bytearray could be optimized away by the compiler, letting
2415 the interpreter segfault instead of raising an error.
2416
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002417- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2418 __next__ method.
2419
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002420- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2421 function no longer attempt to call the __long__ slot to convert an object
2422 to an integer. Only the __int__ and __trunc__ slots are examined.
2423
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002424- Issue #4893: Use NT threading on CE.
2425

2427
Antoine Pitrouab868312009-01-10 15:40:25 +00002428- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2429 common cases are optimized thanks to a dedicated fast path and a moderate
2430 amount of loop unrolling.
2431
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002432- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2433 collecting the oldest generation) so that allocating lots of objects without
2434 destroying them does not show quadratic performance. Based on a proposal by
2435 Martin von Löwis at
2436 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2437
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002438- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002439 having been closed (for instance, a read() call could return some
2440 previously buffered data). Patch by Dmitry Vasiliev.
2441
Antoine Pitrou05608432009-01-09 18:53:14 +00002442- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2443 flag to work properly. Furthermore, when specifying -u, the text stdout
2444 and stderr streams have line-by-line buffering enabled (the default being
2445 to buffer arbitrary chunks of data).
2446
Raymond Hettinger35631532009-01-09 03:58:09 +00002447- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2448 instead of ints (reducing its size from 4 to 8 times thereby reducing
2449 Python's overall memory).
2450
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002451- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2452 an existing .py counterpart, override the co_filename attributes of all
2453 code objects if the original filename is obsolete (which can happen if the
2454 file has been renamed, moved, or if it is accessed through different paths).
2455 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2456
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002457- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2458 one byte. Also fixes the meaning of len() so that it returns the number of
2459 items, rather than the size in bytes.
2460
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002461- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2462
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002463- Issue #4747: When the terminal does not use utf-8, executing a script with
2464 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2465
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002466- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002467 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002468
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002469- Issue #3680: Reference cycles created through a dict, set or deque iterator
2470 did not get collected.
2471
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002472- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2473 where the tp_hash and tp_dict slots are both NULL.
2474
Georg Brandlccc47b62008-12-28 11:44:14 +00002475- Issue #4759: None is now allowed as the first argument of
2476 bytearray.translate(). It was always allowed for bytes.translate().
2477
Skip Montanaro80072cb2008-12-23 03:51:14 +00002478- Added test case to ensure attempts to read from a file opened for writing
2479 fail.
2480
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002481- Issue #3106: Speedup some comparisons (str/str and int/int).

2485
Antoine Pitrou621601a2008-12-17 23:18:19 +00002486- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2487 print elapsed times, not only when some objects are uncollectable /
2488 unreachable. Original patch by Neil Schemenauer.
2489
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002490- Issue #3439: Add a bit_length method to int.
2491
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002492- Issue #2173: When getting device encoding, check that return value of
2493 nl_langinfo is not the empty string. This was causing silent build
2494 failures on OS X.
2495
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002496- Issue #4597: Fixed several opcodes that weren't always propagating
2497 exceptions.
2498
2499- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002500 context manager returns a value that cannot be converted to a bool.
2501
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002502- Issue #4445: Replace "sizeof(PyBytesObject)" with
2503 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2504 bytes instances. On a typical machine this saves 3 bytes of memory
2505 (on average) per allocation of a bytes instance.
2506
Christian Heimesa872de52008-12-05 08:26:55 +00002507- Issue #4533: File read operation was dreadfully slow due to a slowly
2508 growing read buffer. Fixed by using the same growth rate algorithm as
2509 Python 2.x.
2510
Antoine Pitrou5504e892008-12-06 21:27:53 +00002511- Issue #4509: Various issues surrounding resize of bytearray objects to
2512 which there are buffer exports (e.g. memoryview instances).
2513
Georg Brandlf9734072008-12-07 15:30:06 +00002514- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2515 method on file objects with closefd=False. The file descriptor is still
2516 kept open but the file object behaves like a closed file. The ``FileIO``
2517 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002518
Antoine Pitroubc420402008-12-07 20:14:49 +00002519- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2520 larger than 1.

2525
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002526- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2527 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2528 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2529 of using the replace error handler in PyUnicode_DecodeUTF8().
