12Core and Builtins
13-----------------
14
Victor Stinner4aae1eb2010-06-24 22:08:25 +000015- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
16 objects, as described in the documentation.
17
Victor Stinner0fe25a42010-06-17 23:08:50 +000018- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000019 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
20 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000021
Mark Dickinsond35a32e2010-06-17 12:33:22 +000022- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
23 compilation code dealing with unary minus applied to a constant.
24 The removed code was mutating the ST, causing a second compilation
25 to fail.
26
Victor Stinner554f3f02010-06-16 23:33:54 +000027- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
28 mode raises unicode errors. The encoder only supports "strict" and "replace"
29 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000030 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000031
Victor Stinner25e8ec42010-06-25 00:02:38 +000032- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
33 "w*" format instead. Add tests for "w*" format.
34
Victor Stinner06e49dd2010-06-13 18:21:50 +000035- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
36 formats if the string contains a null byte/character. Write unit tests for
37 string formats.
38
Nick Coghlan5e76e942010-06-12 13:42:46 +000039- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
40 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
41 location of the raised exception.
42
Victor Stinner313a1202010-06-11 23:56:51 +000043- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
44 filenames and enable os.fsencode().
45
Benjamin Peterson285a6892010-06-22 19:21:52 +000046- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
47
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000048- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
49 the interpreter with characters outside the Basic Multilingual Plane
50 (higher than 0x10000).
51
Mark Dickinsonc7301312010-06-10 16:05:10 +000052- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
53 raise TypeError instead of giving a DeprecationWarning when a float
54 is parsed using the 'L' code (for long long). (All other integer
55 codes already raise TypeError in this case.)
56
Victor Stinner600d3be2010-06-10 12:00:55 +000057- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
58 enable shortcuts for upper case encoding name. Add also a shortcut for
59 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
60
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000061- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
62 doesn't support "char buffer" anymore in Python3.
63
64- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
65 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
66 like bytearray.
67
Victor Stinner33109a12010-05-28 21:55:10 +000068- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
69 used anymore and it was never documented.
70
Benjamin Peterson95304522010-06-08 14:57:22 +000071- In the str.format(), raise a ValueError when indexes to arguments are too
72 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000073
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000074- Issue #2844: Make int('42', n) consistently raise ValueError for
75 invalid integers n (including n = -909).
76
Mark Dickinsondc787d22010-05-23 13:33:13 +000077- Issue #8188: Introduce a new scheme for computing hashes of numbers
78 (instances of int, float, complex, decimal.Decimal and
79 fractions.Fraction) that makes it easy to maintain the invariant
80 that hash(x) == hash(y) whenever x and y have equal value.
81
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000082- Issue #8748: Fix two issues with comparisons between complex and integer
83 objects. (1) The comparison could incorrectly return True in some cases
84 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
85 (2) The comparison raised an OverflowError for large integers, leading
86 to unpredictable exceptions when combining integers and complex objects
87 in sets or dicts.
88
Victor Stinner7d79b8b2010-05-19 20:40:50 +000089- Issue #8766: Initialize _warnings module before importing the first module.
90 Fix a crash if an empty directory called "encodings" exists in sys.path.
91
Victor Stinner9ca9c252010-05-19 16:53:30 +000092- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
93 encoding and surrogateespace error handler instead of the locale encoding to
94 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
95
Victor Stinner372ac5e2010-05-17 01:26:01 +000096- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
97 (instead of strict) error handler to escape surrogates
98
Victor Stinnerae6265f2010-05-15 16:27:27 +000099- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
100 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000101 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
102 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000103
Victor Stinner59e62db2010-05-15 13:14:32 +0000104- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
105 error handler, not only the default error handler (strict)
106
Victor Stinnerb744ba12010-05-15 12:27:16 +0000107- Issue #8610: Load file system codec at startup, and display a fatal error on
108 failure. Set the file system encoding to utf-8 (instead of None) if getting
109 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
110
Victor Stinner0964ee12010-04-30 16:48:45 +0000111- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
112 PyUnicode_FromString() to support surrogates in the filename and use the
113 right encoding
114
Georg Brandl8569e582010-05-19 20:57:08 +0000115- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
116
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000117- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
118
Benjamin Petersonfb886362010-04-24 18:21:17 +0000119- Issue #8419: Prevent the dict constructor from accepting non-string keyword
120 arguments.
121
Victor Stinner14284c22010-04-23 12:02:30 +0000122- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
123 indirectly Python signal handlers anymore because mywrite() ignores
124 exceptions (KeyboardInterrupt)
125
Victor Stinner31be90b2010-04-22 19:38:16 +0000126- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
127 unicode string (eg. backslashreplace)
128
Victor Stinnerdcb24032010-04-22 12:08:36 +0000129- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
130 you have to convert your bytearray filenames to bytes
131
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000132- Issue #7332: Remove the 16KB stack-based buffer in
133 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
134 benefit compared to the dynamic memory allocation fallback. Patch by
135 Charles-François Natali.
136
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000137- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
138 passed to bytes or bytearray.
139
Philip Jenvey0805ca32010-04-07 04:04:10 +0000140- Issue #7301: Add environment variable $PYTHONWARNINGS.
141
Benjamin Petersond856ab62010-04-06 21:55:16 +0000142- Issue #8329: Don't return the same lists from select.select when no fds are
143 changed.
144
Mark Dickinson3318d292010-04-06 16:53:17 +0000145- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
146 on 64-bit machines. The shift count for either left or right shift is
147 permitted to be up to sys.maxsize.
148
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000149- Ensure that tokenization of identifiers is not affected by locale.

156 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000157
Victor Stinner120c2122010-03-25 00:30:28 +0000158- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
159 is unknown

162
Mark Dickinsond59b4162010-03-13 11:34:40 +0000163- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
164 PyMemberDefs could produce an internal error; raise TypeError instead.
165
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000166- Issue #7845: Rich comparison methods on the complex type now return
167 NotImplemented rather than raising a TypeError when comparing with an
168 incompatible type; this allows user-defined classes to implement their own
169 comparisons with complex.
170
Victor Stinner52f6dd72010-03-12 14:45:56 +0000171- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
172 (SIGINT). If an error occurs while importing the site module, the error is
173 printed and Python exits. Initialize the GIL before importing the site
174 module.
175
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000176- Issue #7173: Generator finalization could invalidate sys.exc_info().

200 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
201 and PyOS_string_to_double instead. See issue #5835 for the original
202 deprecations.
203
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000204- Issue #7385: Fix a crash in `MemoryView_FromObject` when
205 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
206
Mark Dickinsonbc099642010-01-29 17:27:24 +0000207- Issue #7788: Fix an interpreter crash produced by deleting a list
208 slice with very large step value.
209
Eric Smithf7bb5782010-01-27 00:44:57 +0000210- Issue #7766: Change sys.getwindowsversion() return value to a named
211 tuple and add the additional members returned in an OSVERSIONINFOEX
212 structure. The new members are service_pack_major, service_pack_minor,
213 suite_mask, and product_type.
214
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000215- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
216 could crash in many places because of the PyByteArray_AS_STRING() macro
217 returning NULL. The macro now returns a statically allocated empty
218 string instead.
219
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000220- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
221 where the right hand operand is a set of constants, by turning the set into
222 a frozenset and pre-building it as a constant. The comparison operation
223 is made against the constant instead of building a new set each time it is
224 executed (a similar optimization already existed which turned a list of
225 constants into a pre-built tuple). Patch and additional tests by Dave
226 Malcolm.
227
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000228- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

233 alpha 2, including: (1) a serious 'wrong output' bug that could
234 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
235 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000236 strings corresponding to subnormal values, (3) a memory leak for
237 some values large enough to cause overflow, and (4) a number of
238 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000239
Benjamin Petersonaea44282010-01-04 01:10:28 +0000240- The __complex__ method is now looked up on the class of instances to make it

245
Benjamin Petersond12362a2009-12-30 19:44:54 +0000246- Issue #7604: Deleting an unset slotted attribute did not raise an
247 AttributeError.

250 negative zero) in ** operator. The behaviour now conforms to that
251 described in C99 Annex F.
252
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000253- Issue #1811: improve accuracy and cross-platform consistency for
254 true division of integers: the result of a/b is now correctly
255 rounded for ints a and b (at least on IEEE 754 platforms), and in
256 particular does not depend on the internal representation of an int.
257
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000258- Issue #6834: replace the implementation for the 'python' and 'pythonw'
259 executables on OSX.
260
261 These executables now work properly with the arch(1) command:
262 ``arch -ppc python`` will start a universal binary version of python
263 in PPC mode (unlike previous releases).
264
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000265- Issue #7466: segmentation fault when the garbage collector is called
266 in the middle of populating a tuple. Patch by Florent Xicluna.

280 implement the relevant rich comparison methods.
281
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000282- Issue #7298: fixes for range and reversed(range(...)). Iteration
283 over range(a, b, c) incorrectly gave an empty iterator when a, b and
284 c fit in C long but the length of the range did not. Also fix
285 several cases where reversed(range(a, b, c)) gave wrong results, and
286 fix a refleak for reversed(range(a, b, c)) with large arguments.
287
Raymond Hettingerfc438512009-11-01 20:55:33 +0000288- Issue #7244: itertools.izip_longest() no longer ignores exceptions

414 has '\0' at the end.
415
Mark Dickinsonde604012010-01-01 19:27:32 +0000416- Issue #5080: The argument parsing functions PyArg_ParseTuple,
417 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
418 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
419 DeprecationWarning for float arguments passed with the 'L' format
420 code. This will become a TypeError in a future version of Python,
421 to match the behaviour of the other integer format codes.
422

432 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
433 should used for accessing the d_type and d_name members of structures
434 using PyDescr_COMMON.

Mark Dickinson08ade6f2010-06-11 10:44:52 +0000486 now permitted, returning a result based on the exact numerical
487 values of the operands. This builds on issue #2531, which allowed
488 Decimal-to-float comparisons; all comparisons involving numeric
489 types (bool, int, float, complex, Decimal, Fraction) should now
490 act as expected.
491

Victor Stinnere125f132010-05-15 21:04:43 +0000607- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
608 error messages when accessing undefined class attributes because of the cheap
609 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000610 The cheap inheritance has been deprecated.
611
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000612- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
613 Patch by Tres Seaver.
614
Victor Stinnerde629d42010-05-05 21:43:57 +0000615- Issue #8390: tarfile uses surrogateespace as the default error handler
616 (instead of replace in read mode or strict in write mode)
617
Barry Warsaw83d89982010-05-05 16:18:31 +0000618- Issue #7755: Use an unencumbered audio file for tests.
619
Ronald Oussorenac764d32010-05-05 15:32:33 +0000620- Issue #8621: uuid.uuid4() returned the same sequence of values in the
621 parent and any children created using ``os.fork`` on MacOS X 10.6.
622
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000623- Issue #8567: Fix precedence of signals in Decimal module: when a
624 Decimal operation raises multiple signals and more than one of those
625 signals is trapped, the specification determines the order in which
626 the signals should be handled. In many cases this order wasn't
627 being followed, leading to the wrong Python exception being raised.
628
Antoine Pitrou6be88762010-05-03 16:48:20 +0000629- Issue #7865: The close() method of :mod:`io` objects should not swallow
630 exceptions raised by the implicit flush(). Also ensure that calling
631 close() several times is supported. Patch by Pascal Chambon.
632
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000633- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
634 gc.DEBUG_STATS.
635
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000636- Issue #8354: The siginterrupt setting is now preserved for all signals,
637 not just SIGCHLD.
638
Georg Brandl25106ce2010-05-21 21:49:47 +0000639- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000640 webbrowser.get("safari").
641
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000642- Issue #8464: tarfile no longer creates files with execute permissions set
643 when mode="w|" is used.
644
Antoine Pitroubf043492010-04-29 10:11:46 +0000645- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
646 of the Linux kernel. Patch by Yaniv Aknin.
647
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000648- Issue #8295: Added shutil.unpack_archive.
649
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000650- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
651 It should correctly return an empty response now.
652
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000653- Issue #8546: Reject None given as the buffering argument to _pyio.open.
654
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000655- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
656 Sridhar Ratnakumar.
657
R. David Murrayad78d152010-04-27 02:45:53 +0000658- Issue #6656: fix locale.format_string to handle escaped percents
659 and mappings.
660
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000661- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
662 where the method could block indefinitely if called just before the
663 event loop started running. This also fixes the occasional freezes
664 witnessed in test_httpservers.
665
Antoine Pitrou40f08742010-04-24 22:04:40 +0000666- Issue #8524: When creating an SSL socket, the timeout value of the
667 original socket wasn't retained (instead, a socket with a positive timeout
668 would be turned into a non-blocking SSL socket).
669
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000670- Issue #5103: SSL handshake would ignore the socket timeout and block
671 indefinitely if the other end didn't respond.
672
673- The do_handshake() method of SSL objects now adjusts the blocking mode of
674 the SSL structure if necessary (as other methods already do).
675
Victor Stinner13bb71c2010-04-23 21:41:56 +0000676- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
677 and bytes strings for environment keys and values
678
Victor Stinner4d078042010-04-23 19:28:32 +0000679- Issue #8467: Pure Python implementation of subprocess encodes the error
680 message using surrogatepass error handler to support surrogates in the
681 message
682
Victor Stinner349fd522010-04-23 10:56:17 +0000683- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
684
Sean Reifscheider13daf122010-04-23 09:29:52 +0000685- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
686 the string "python" as the *ident*. openlog() arguments are all optional
687 and keywords.
688
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000689- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
690 a non-infinite timeout. Also make that method friendlier with applications
691 wanting to continue using the socket in clear-text mode, by disabling
692 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
693
Antoine Pitrou7062db82010-04-22 13:30:10 +0000694- Issue #8496: make mailcap.lookup() always return a list, rather than an
695 iterator. Patch by Gregory Nofi.
696
Victor Stinner35466c52010-04-22 11:23:23 +0000697- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
698 collation name contains a surrogate character.
699
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000700- Issue #8484: Load all ciphers and digest algorithms when initializing
701 the _ssl extension, such that verification of some SSL certificates
702 doesn't fail because of an "unknown algorithm".
703
Tarek Ziadéfb437512010-04-20 08:57:33 +0000704- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
705
Victor Stinnere125f132010-05-15 21:04:43 +0000706- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000707 shutil.copytree.
708
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000709- Issue #4814: timeout parameter is now applied also for connections resulting
710 from PORT/EPRT commands.
711
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000712- Issue #8463: added missing reference to bztar in shutil's documentation.
713
Ronald Oussoren84151202010-04-18 20:46:11 +0000714- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
715 (as long as the user didn't specify 'automatic proxy configuration').
716
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000717- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
718 code as stated in RFC-959 at chapter 5.4.
719
Victor Stinner738446f02010-04-18 00:00:44 +0000720- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
721 surrogates.
722
Antoine Pitrou0454af92010-04-17 23:51:58 +0000723- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000724 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000725
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000726- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
727 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
728
Victor Stinner0e59cc32010-04-16 23:49:32 +0000729- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
730 the current working directory.
731
Victor Stinner5bfe1462010-04-16 13:28:05 +0000732- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
733 using backslashreplace error handler
734
Victor Stinnercfa72782010-04-16 11:45:13 +0000735- Issue #8412: os.system() now accepts bytes, bytearray and str with
736 surrogates.
737
Senthil Kumaranad02d232010-04-16 03:02:13 +0000738- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
739 Locke and Hans Ulrich Niedermann.
740
R. David Murrayd48739f2010-04-14 18:59:18 +0000741- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
742
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000743- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
744 module now takes an optional timeout argument in seconds. Timeout support
745 relies on the system threading library, so as to avoid a semi-busy wait
746 loop.
747
Victor Stinner485fb562010-04-13 11:07:24 +0000748- Issue #8383: pickle and pickletools use surrogatepass error handler when
749 encoding unicode as utf8 to support lone surrogates and stay compatible with
750 Python 2.x and 3.0
751
R. David Murrayb2416e52010-04-12 16:58:02 +0000752- Issue #7585: difflib context and unified diffs now place a tab between
753 filename and date, conforming to the 'standards' they were originally
754 designed to follow. This improves compatibility with patch tools.
755
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000756- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
757 character sets will now consistently use a Content-Transfer-Encoding of
758 7bit rather than sometimes being marked as 8bit.
759
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000760- Issue #8375: test_distutils now checks if the temporary directory are still
761 present before it cleans them.
762
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000763- Issue #8374: Update the internal alias table in the :mod:`locale` module
764 to cover recent locale changes and additions.
765
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000766- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
767 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
768 and `ssl.OPENSSL_VERSION_NUMBER`.
769
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000770- Add functools.total_ordering() and functools.cmp_to_key().
771
Mark Dickinson089b00c2010-04-03 15:51:03 +0000772- Issue #8257: The Decimal construct now accepts a float instance
773 directly, converting that float to a Decimal of equal value:
774
775 >>> Decimal(1.1)
776 Decimal('1.100000000000000088817841970012523233890533447265625')
777
Mark Dickinson98127c32010-04-03 11:18:52 +0000778- Issue #8294: The Fraction constructor now accepts Decimal and float
779 instances directly.
780
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000781- Issue #7279: Comparisons involving a Decimal signaling NaN now
782 signal InvalidOperation instead of returning False. (Comparisons
783 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
784 are now hashable; Decimal signaling NaNs remain unhashable.
785
786- Issue #2531: Comparison operations between floats and Decimal
787 instances now return a result based on the numeric values of the
788 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000789 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000790 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000791
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000792- Added a subtract() method to collections.Counter().
793
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000794- Issue #8233: When run as a script, py_compile.py optionally takes a single
795 argument `-` which tells it to read files to compile from stdin. Each line
796 is read on demand and the named file is compiled immediately. (Original
797 patch by Piotr Ożarowski).
798
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000799- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
800 form feed (0x0C) are now considered linebreaks, as specified in Unicode
801 Standard Annex #14. See issue #7643.
802 http://www.unicode.org/reports/tr14/
803
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000804- Comparisons using one of <, <=, >, >= between a complex instance and
805 a Fractions instance now raise TypeError instead of returning
806 True/False. This makes Fraction <=> complex comparisons consistent with
807 int <=> complex, float <=> complex, and complex <=> complex comparisons.
808
Antoine Pitrou39b35432010-03-23 00:25:54 +0000809- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
810 some methods (such as oss_mixer_device.fileno()) were not available.
811 Initial patch by Bertrand Janin.
812
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000813- Issue #8205: Remove the "Modules" directory from sys.path when Python is
814 running from the build directory (POSIX only).
815
Antoine Pitrou910bd512010-03-22 20:11:09 +0000816- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
817 didn't support chflags() (for example ZFS under FreeBSD). The error is
818 now silenced.
819
R. David Murrayca2edce2010-03-22 17:48:48 +0000820- Issue #7860: platform.uname now reports the correct 'machine' type
821 when Python is running in WOW64 mode on 64 bit Windows.
822
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000823- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
824 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
825 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000826
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000827- Issue #4282: Fix the main function of the profile module for a non-ASCII
828 script, open the file in binary mode and not in text mode with the default
829 (utf8) encoding.
830
Florent Xicluna54467e02010-03-21 12:29:50 +0000831- Issue #8179: Fix macpath.realpath() on a non-existing path.
832
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000833- Issue #8024: Update the Unicode database to 5.2.
834
Benjamin Peterson00888932010-03-18 22:37:38 +0000835- Issue #8168: py_compile now handles files with utf-8 BOMS.
836
Benjamin Peterson689a5582010-03-18 22:29:52 +0000837- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
838 detected.
839
Martin v. Löwis4b003072010-03-16 13:19:21 +0000840- Issue #6716/2: Backslash-replace error output in compilall.
841
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000842- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
843 with Tcl/Tk-8.5.
844
Matthias Klosec33b9022010-03-16 00:36:26 +0000845- Issue #8140: extend compileall to compile single files. Add -i option.
846
Matthias Klose82f60912010-03-15 13:46:04 +0000847- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
848 the locale.
849
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000850- The internals of the subprocess module on POSIX systems have been replaced
851 by an extension module (_posixsubprocess) so that the fork()+exec() can be
852 done safely without the possibility of deadlock in multithreaded applications.
853
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000854- subprocess.Popen now has restore_signals and start_new_session features.
855 The default of restore_signals=True is a new behavior compared to earlier
856 Python versions. This means that signals such as SIGPIPE are not ignored
857 by default in subprocesses launched by Python (Issue #1652).
858
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000859- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
860 cElementTree module is updated too.
861
Victor Stinnerb33062c2010-03-12 14:27:16 +0000862- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
863 an non existent program name and Python is unable to retrieve the real
864 program name
865
Florent Xiclunaa4707382010-03-11 00:05:17 +0000866- Issue #7880: Fix sysconfig when the python executable is a symbolic link.

Ezio Melottib92ed7c2010-03-06 15:24:08 +0000868- Issue #6509: fix re.sub to work properly when the pattern, the string, and
869 the replacement were all bytes. Patch by Antoine Pitrou.
870
Gerhard Häringf9cee222010-03-05 15:20:03 +0000871- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
872 bugs and allows loading SQLite extensions from shared libraries.
873
Ezio Melottida227042010-03-14 11:51:00 +0000874- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Victor Stinnercee3ae82010-03-04 00:29:24 +0000877- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
878 reset also the pointer to the current pointer context.
879
Lars Gustäbel01385812010-03-03 12:08:54 +0000880- Issue #7232: Add support for the context manager protocol to the TarFile

887
Florent Xiclunac279ebf2010-02-27 11:31:21 +0000888- Issue #691291: codecs.open() should not convert end of lines on reading and
889 writing.
890
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000891- Issue #7869: logging: improved diagnostic for format-time errors.

1118 to execute file paths that refer to source or compiled Python files as well
1119 as zipfiles, directories and other valid sys.path entries that contain a
1120 __main__.py file. This allows applications that run other Python scripts to

Victor Stinnere125f132010-05-15 21:04:43 +00001140 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001141 recursive locks as fast as regular non-recursive locks (previously,
1142 they were slower by 10x to 15x).

1300 relation to other methods required by the ABCs.
1301
Brett Cannon64ef00f2009-07-20 03:19:18 +00001302- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
1303 the documentation said it did even though the code in PyLoader relied on the

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001351- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1352 10,000. Prior to this change, timezone adjustment in utctimetuple()
1353 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1354 raised in these edge cases.
1355
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001356- Issue #6641: The ``datetime.strptime`` method now supports the
1357 ``%z`` directive. When the ``%z`` directive is present in the
1358 format string, an aware ``datetime`` object is returned with
1359 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1360 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1361 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1362 without ``%z`` is discarded.
1363
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001364- Issue #5094: The ``datetime`` module now has a simple concrete class
1365 implementing ``datetime.tzinfo`` interface. Instances of the new
1366 class, ``datetime.timezone``, return fixed name and UTC offset from
1367 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1368 method always returns ``None``. A class attribute, ``utc`` contains
1369 an instance representing the UTC timezone. Original patch by Rafe
1370 Kaplan.
1371
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001372- Issue #8973: Add __all__ to struct module; this ensures that
1373 help(struct) includes documentation for the struct.Struct class.
1374
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001375- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001376 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001377 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00001378
Stefan Kraha3ac44e2010-06-08 14:00:52 +00001379- Issue #7384: If the system readline library is linked against ncurses,
1380 the curses module must be linked against ncurses as well. Otherwise it
1381 is not safe to load both the readline and curses modules in an application.
1382
Brian Curtin60853212010-05-26 17:43:50 +00001383- Issue #2810: Fix cases where the Windows registry API returns
1384 ERROR_MORE_DATA, requiring a re-try in order to get the complete result.
1385
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001386- Issue #8692: Optimize math.factorial: replace the previous naive
1387 algorithm with an improved 'binary-split' algorithm that uses fewer
1388 multiplications and allows many of the multiplications to be
1389 performed using plain C integer arithmetic instead of PyLong
1390 arithmetic. Also uses a lookup table for small arguments.
1391
Mark Dickinson85eacea2010-05-10 16:27:45 +00001392- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1393 overflow checks in the audioop module.
1394
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001395- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1396 calculating with integer arithmetic instead of float arithmetic internally):
1397 the result is now always correctly rounded, and is equivalent to td /
1398 timedelta(seconds=1).
1399
Mark Dickinson7c186e22010-04-20 22:32:49 +00001400- Issue #2706: Allow division of a timedelta by another timedelta:
1401 timedelta / timedelta, timedelta % timedelta, timedelta // timedelta
1402 and divmod(timedelta, timedelta) are all supported.
1403
Victor Stinnerfebecd82010-04-16 12:07:30 +00001404- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
1405
Mark Dickinsonc5935772010-04-03 15:54:36 +00001406- Issue #8300: When passing a non-integer argument to struct.pack with any
1407 integer format code, struct.pack first attempts to convert the non-integer
1408 using its __index__ method. If that method is non-existent or raises
1409 TypeError it goes on to try the __int__ method, as described below.
1410
Matthias Klosea8349752010-03-15 13:25:28 +00001411- Issue #8142: Update libffi to the 3.0.9 release.

1660 leak-chasing test runs give sensible results. The previous method of
1661 reaping threads could return successfully while some Thread objects were
1662 still referenced. This also introduces a new private function:
1663 :func:`_thread._count()`.
1664
R. David Murray27144602009-10-19 15:26:16 +00001665- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1666 longer runs the risk of causing the worker thread to fail.
1667
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001668- Issue #7055: test___all__ now greedily detects all modules which have an
1669 __all__ attribute, rather than using a hardcoded and incomplete list.

1673 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001674
Mark Dickinson2e304402009-10-04 18:43:54 +00001675- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1676
Brett Cannon3c273842009-07-20 00:14:29 +00001677- Fixed tests in importlib.test.source.test_abc_loader that were masking
1678 the proper exceptions that should be raised for missing or improper code

Raymond Hettinger2bcde142009-05-29 04:52:27 +00001830- Issue #5982: staticmethod and classmethod now expose the wrapped
1831 function with __func__.
1832
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001833- Added support for multiple context managers in the same with-statement.
1834 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001836- Issue #5829: complex("1e500") no longer raises OverflowError. This
1837 makes it consistent with float("1e500") and interpretation of real
1838 and imaginary literals.
1839
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001840- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1845 (1) inf and nan strings with trailing whitespace were incorrectly
1846 rejected; (2) parsing of strings representing infinities and nans
1847 was locale aware; and (3) the interpretation of fromhex('-nan')
1848 didn't match that of float('-nan').

1865
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001866- In unittest, using a skipping decorator on a class is now equivalent to

1868
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001869- Issue #6050: Don't fail extracting a directory from a zipfile if
1870 the directory already exists.
1871
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001872- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1873 than an int, which makes some operations possible under 64-bit Linux (e.g.
1874 DN_MULTISHOT with F_NOTIFY).
1875
Antoine Pitrou716c4442009-05-23 19:04:03 +00001876- Issue #5761: Add the name of the underlying file to the repr() of various

Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001882- Issue #1983: Fix functions taking or returning a process identifier to use
1883 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1884 a process identifier type wider than the standard C integer type.
1885

1897
Antoine Pitroue4501852009-05-14 18:55:55 +00001898- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1899 library. This means, for example, that opening an UTF-16 text file in
1900 append mode doesn't add a BOM at the end of the file if the file isn't
1901 empty.
1902
R. David Murray74b89242009-05-13 17:33:03 +00001903- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'

1905 corrects a pydoc regression.
1906
R. David Murray99352742009-05-07 18:24:38 +00001907- Issue 5955: aifc's close method did not close the file it wrapped,
1908 now it does. This also means getfp method now returns the real fp.

1953
Mark Dickinson865e01a2009-05-07 16:37:01 +00001954- Issue #5914: Add new C API function PyOS_string_to_double, and
1955 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1956
Eric Smith741191f2009-05-06 13:08:15 +00001957- Issue #3382: float.__format__, complex.__format__, and %-formatting
1958 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1959 affects nan -> NAN and inf -> INF.
1960
Mark Hammond5a607a32009-05-06 08:04:54 +00001961- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1962 in all operations, including splitdrive, split, etc. splitunc() now issues
1963 a PendingDeprecation warning.
1964
Eric Smith63376222009-05-05 14:04:18 +00001965- Issue #5920: For float.__format__, change the behavior with the
1966 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1967 to be like 'g' but with at least one decimal point and with a
1968 default precision of 12. Previously, the behavior the same but with
1969 a default precision of 6. This more closely matches str(), and
1970 reduces surprises when adding alignment flags to the empty
1971 presentation type. This also affects the new complex.__format__ in
1972 the same way.
1973
Martin v. Löwis011e8422009-05-05 04:43:17 +00001974- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1975
R. David Murrayb18500d2009-05-04 22:59:07 +00001976- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1977 shadowed by classtype's, even if it was None. property now
1978 inserts the __doc__ into the subclass instance __dict__.
1979
Antoine Pitrou244651a2009-05-04 18:56:13 +00001980- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1981 sequences. Patch by Nick Barnes and Victor Stinner.
1982
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001983- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001984
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001985- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1986 received a new method, detach(). detach() disconnects the underlying stream
1987 from the buffer or text IO and returns it.
1988
Mark Dickinson33841c32009-05-01 15:37:04 +00001989- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1990 floats with absolute value over 1e50. Also remove length
1991 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1992 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001993
Eric Smith741191f2009-05-06 13:08:15 +00001994- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001995 format(complex(1, 2./3), '.5') now produces a sensible result.
1996
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001997- Issue #5864: Fix empty format code formatting for floats so that it
1998 never gives more than the requested number of significant digits.
1999
Eric Smith6dc46f52009-04-27 20:39:49 +00002000- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2001 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2002
Eric Smithcc32a112009-04-26 21:35:14 +00002003- Issue #5835: Deprecate PyOS_ascii_formatd.
2004
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002005- Issue #4971: Fix titlecase for characters that are their own
2006 titlecase, but not their own uppercase.
2007
Benjamin Peterson193152c2009-04-25 01:08:45 +00002008- Issue #5283: Setting __class__ in __del__ caused a segfault.
2009
Mark Dickinsonad476da2009-04-23 19:14:16 +00002010- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2011 z involves nans, infs or negative zeros.
2012
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002013- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002014
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002015- Issue #1869 (and many duplicates): make round(x, n) correctly
2016 rounded for a float x, by using the decimal <-> binary conversions
2017 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2018 consistently agrees with format(x, '.2f').
2019
Benjamin Petersonae937c02009-04-18 20:54:08 +00002020- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2021 some builtin types.
2022
Eric Smith0923d1d2009-04-16 20:16:10 +00002023- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2024
Eric Smith35e84722009-04-16 20:21:28 +00002025- Issue #5515: str.format() type 'n' combined with commas and leading
2026 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002027
2028- Implement PEP 378, Format Specifier for Thousands Separator, for
2029 floats.
2030
Mark Dickinson3370cce2009-04-17 22:40:53 +00002031- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002032 1e11, not 1e12. This avoids printing 13 significant digits in
2033 situations where only 12 of them are correct. Example problem
2034 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2035 long time.)
2036
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002037- Issue #1580: On most platforms, use a 'short' float repr: for a
2038 finite float x, repr(x) now outputs a string based on the shortest
2039 sequence of decimal digits that rounds to x. Previous behaviour was
2040 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002041 Another minor difference is that the new repr switches to
2042 exponential notation at 1e16 instead of the previous 1e17; this
2043 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002044
2045 There's a new sys attribute sys.float_repr_style, which takes
2046 the value 'short' to indicate that we're using short float repr,
2047 and 'legacy' if the short float repr isn't available for one
2048 reason or another.
2049
2050 The float repr change involves incorporating David Gay's 'perfect
2051 rounding' code into the Python core (it's in Python/dtoa.c). As a
2052 secondary consequence, all string-to-float and float-to-string
2053 conversions (including all float formatting operations) will be
2054 correctly rounded on these platforms.
2055
2056 See issue 1580 discussions for details of platforms for which
2057 this change does not apply.

Georg Brandlabc38772009-04-12 15:51:51 +00002061- The string.maketrans() function is deprecated; there is a new static method
2062 maketrans() on the bytes and bytearray classes. This removes confusion about
2063 the types string.maketrans() is supposed to work with, and mirrors the
2064 methods available on the str class.

2356 rotating the object pointer by 4 bits to the right.
2357
Mark Dickinson87ec0852009-02-09 17:15:59 +00002358- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2359 it now forces its argument to double before testing for infinity.
2360
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002361- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002370
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002371- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002372 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002374- Issue #4707: round(x, n) now returns an integer if x is an integer.
2375 Previously it returned a float.
2376
Antoine Pitroub52ec782009-01-25 16:34:23 +00002377- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2378 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2379 evaluation loop is compiled with a new dispatch mechanism which gives
2380 speedups of up to 20%, depending on the system, on various benchmarks.
2381

2390 optional module state data.
2391
Mark Dickinson8055afd2009-01-17 10:04:45 +00002392- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2393 type to (void *).
2394
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002395- Issue #4935: The overflow checking code in the expandtabs() method common
2396 to str, bytes and bytearray could be optimized away by the compiler, letting
2397 the interpreter segfault instead of raising an error.
2398
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002399- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2400 __next__ method.
2401
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002402- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2403 function no longer attempt to call the __long__ slot to convert an object
2404 to an integer. Only the __int__ and __trunc__ slots are examined.

2409
Antoine Pitrouab868312009-01-10 15:40:25 +00002410- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2411 common cases are optimized thanks to a dedicated fast path and a moderate
2412 amount of loop unrolling.
2413
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002414- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2415 collecting the oldest generation) so that allocating lots of objects without
2416 destroying them does not show quadratic performance. Based on a proposal by
2417 Martin von Löwis at
2418 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2419
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002420- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002421 having been closed (for instance, a read() call could return some
2422 previously buffered data). Patch by Dmitry Vasiliev.
2423
Antoine Pitrou05608432009-01-09 18:53:14 +00002424- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2425 flag to work properly. Furthermore, when specifying -u, the text stdout
2426 and stderr streams have line-by-line buffering enabled (the default being
2427 to buffer arbitrary chunks of data).
2428
Raymond Hettinger35631532009-01-09 03:58:09 +00002429- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2430 instead of ints (reducing its size from 4 to 8 times thereby reducing
2431 Python's overall memory).
2432
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002433- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2434 an existing .py counterpart, override the co_filename attributes of all
2435 code objects if the original filename is obsolete (which can happen if the
2436 file has been renamed, moved, or if it is accessed through different paths).
2437 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2438
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002439- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2440 one byte. Also fixes the meaning of len() so that it returns the number of
2441 items, rather than the size in bytes.
2442
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002443- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2444
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002445- Issue #4747: When the terminal does not use utf-8, executing a script with
2446 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2447

2456
Georg Brandlccc47b62008-12-28 11:44:14 +00002457- Issue #4759: None is now allowed as the first argument of
2458 bytearray.translate(). It was always allowed for bytes.translate().
2459
Skip Montanaro80072cb2008-12-23 03:51:14 +00002460- Added test case to ensure attempts to read from a file opened for writing
2461 fail.

2473
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002474- Issue #2173: When getting device encoding, check that return value of
2475 nl_langinfo is not the empty string. This was causing silent build
2476 failures on OS X.
2477
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002478- Issue #4597: Fixed several opcodes that weren't always propagating
2479 exceptions.
2480
2481- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002482 context manager returns a value that cannot be converted to a bool.
2483
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002484- Issue #4445: Replace "sizeof(PyBytesObject)" with
2485 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2486 bytes instances. On a typical machine this saves 3 bytes of memory
2487 (on average) per allocation of a bytes instance.
2488
Christian Heimesa872de52008-12-05 08:26:55 +00002489- Issue #4533: File read operation was dreadfully slow due to a slowly
2490 growing read buffer. Fixed by using the same growth rate algorithm as
2491 Python 2.x.
2492
Antoine Pitrou5504e892008-12-06 21:27:53 +00002493- Issue #4509: Various issues surrounding resize of bytearray objects to
2494 which there are buffer exports (e.g. memoryview instances).
2495
Georg Brandlf9734072008-12-07 15:30:06 +00002496- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2497 method on file objects with closefd=False. The file descriptor is still
2498 kept open but the file object behaves like a closed file. The ``FileIO``
2499 object also got a new readonly attribute ``closefd``.

2507
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002508- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2509 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2510 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2511 of using the replace error handler in PyUnicode_DecodeUTF8().
