16
Victor Stinner4aae1eb2010-06-24 22:08:25 +000017- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
18 objects, as described in the documentation.
19
Victor Stinner0fe25a42010-06-17 23:08:50 +000020- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000021 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
22 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000023
Mark Dickinsond35a32e2010-06-17 12:33:22 +000024- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
25 compilation code dealing with unary minus applied to a constant.
26 The removed code was mutating the ST, causing a second compilation
27 to fail.
28
Victor Stinner554f3f02010-06-16 23:33:54 +000029- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
30 mode raises unicode errors. The encoder only supports "strict" and "replace"
31 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000032 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000033
Victor Stinner25e8ec42010-06-25 00:02:38 +000034- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use

38 formats if the string contains a null byte/character. Write unit tests for
39 string formats.
40
Nick Coghlan5e76e942010-06-12 13:42:46 +000041- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
42 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
43 location of the raised exception.
44
Victor Stinner313a1202010-06-11 23:56:51 +000045- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
46 filenames and enable os.fsencode().
47

49
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000050- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
51 the interpreter with characters outside the Basic Multilingual Plane
52 (higher than 0x10000).
53
Mark Dickinsonc7301312010-06-10 16:05:10 +000054- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
55 raise TypeError instead of giving a DeprecationWarning when a float
56 is parsed using the 'L' code (for long long). (All other integer
57 codes already raise TypeError in this case.)
58
Victor Stinner600d3be2010-06-10 12:00:55 +000059- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
60 enable shortcuts for upper case encoding name. Add also a shortcut for
61 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
62
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000063- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
64 doesn't support "char buffer" anymore in Python3.
65
66- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
67 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
68 like bytearray.
69
Victor Stinner33109a12010-05-28 21:55:10 +000070- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
71 used anymore and it was never documented.
72
Benjamin Peterson95304522010-06-08 14:57:22 +000073- In the str.format(), raise a ValueError when indexes to arguments are too
74 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000075
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000076- Issue #2844: Make int('42', n) consistently raise ValueError for
77 invalid integers n (including n = -909).
78
Mark Dickinsondc787d22010-05-23 13:33:13 +000079- Issue #8188: Introduce a new scheme for computing hashes of numbers
80 (instances of int, float, complex, decimal.Decimal and
81 fractions.Fraction) that makes it easy to maintain the invariant
82 that hash(x) == hash(y) whenever x and y have equal value.
83
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000084- Issue #8748: Fix two issues with comparisons between complex and integer
85 objects. (1) The comparison could incorrectly return True in some cases
86 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
87 (2) The comparison raised an OverflowError for large integers, leading
88 to unpredictable exceptions when combining integers and complex objects
89 in sets or dicts.
90
Victor Stinner7d79b8b2010-05-19 20:40:50 +000091- Issue #8766: Initialize _warnings module before importing the first module.
92 Fix a crash if an empty directory called "encodings" exists in sys.path.
93
Victor Stinner9ca9c252010-05-19 16:53:30 +000094- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
95 encoding and surrogateespace error handler instead of the locale encoding to
96 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
97
Victor Stinner372ac5e2010-05-17 01:26:01 +000098- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
99 (instead of strict) error handler to escape surrogates
100
Victor Stinnerae6265f2010-05-15 16:27:27 +0000101- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
102 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000103 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
104 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000105
Victor Stinner59e62db2010-05-15 13:14:32 +0000106- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
107 error handler, not only the default error handler (strict)
108
Victor Stinnerb744ba12010-05-15 12:27:16 +0000109- Issue #8610: Load file system codec at startup, and display a fatal error on
110 failure. Set the file system encoding to utf-8 (instead of None) if getting
111 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
112
Victor Stinner0964ee12010-04-30 16:48:45 +0000113- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
114 PyUnicode_FromString() to support surrogates in the filename and use the
115 right encoding
116
Georg Brandl8569e582010-05-19 20:57:08 +0000117- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
118
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000119- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
120
Benjamin Petersonfb886362010-04-24 18:21:17 +0000121- Issue #8419: Prevent the dict constructor from accepting non-string keyword
122 arguments.
123
Victor Stinner14284c22010-04-23 12:02:30 +0000124- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
125 indirectly Python signal handlers anymore because mywrite() ignores
126 exceptions (KeyboardInterrupt)
127
Victor Stinner31be90b2010-04-22 19:38:16 +0000128- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
129 unicode string (eg. backslashreplace)
130
Victor Stinnerdcb24032010-04-22 12:08:36 +0000131- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
132 you have to convert your bytearray filenames to bytes
133
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000134- Issue #7332: Remove the 16KB stack-based buffer in
135 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
136 benefit compared to the dynamic memory allocation fallback. Patch by
137 Charles-François Natali.
138
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000139- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
140 passed to bytes or bytearray.

145 changed.
146
Mark Dickinson3318d292010-04-06 16:53:17 +0000147- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
148 on 64-bit machines. The shift count for either left or right shift is
149 permitted to be up to sys.maxsize.
150
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000151- Ensure that tokenization of identifiers is not affected by locale.

164
Mark Dickinsond59b4162010-03-13 11:34:40 +0000165- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
166 PyMemberDefs could produce an internal error; raise TypeError instead.
167
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000168- Issue #7845: Rich comparison methods on the complex type now return
169 NotImplemented rather than raising a TypeError when comparing with an
170 incompatible type; this allows user-defined classes to implement their own
171 comparisons with complex.
172
Victor Stinner52f6dd72010-03-12 14:45:56 +0000173- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
174 (SIGINT). If an error occurs while importing the site module, the error is
175 printed and Python exits. Initialize the GIL before importing the site
176 module.
177
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000178- Issue #7173: Generator finalization could invalidate sys.exc_info().

204 deprecations.
205
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000206- Issue #7385: Fix a crash in `MemoryView_FromObject` when
207 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
208
Mark Dickinsonbc099642010-01-29 17:27:24 +0000209- Issue #7788: Fix an interpreter crash produced by deleting a list
210 slice with very large step value.
211
Eric Smithf7bb5782010-01-27 00:44:57 +0000212- Issue #7766: Change sys.getwindowsversion() return value to a named
213 tuple and add the additional members returned in an OSVERSIONINFOEX
214 structure. The new members are service_pack_major, service_pack_minor,
215 suite_mask, and product_type.
216
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000217- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
218 could crash in many places because of the PyByteArray_AS_STRING() macro
219 returning NULL. The macro now returns a statically allocated empty
220 string instead.
221
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000222- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
223 where the right hand operand is a set of constants, by turning the set into
224 a frozenset and pre-building it as a constant. The comparison operation
225 is made against the constant instead of building a new set each time it is
226 executed (a similar optimization already existed which turned a list of
227 constants into a pre-built tuple). Patch and additional tests by Dave
228 Malcolm.
229
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000230- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()

235 alpha 2, including: (1) a serious 'wrong output' bug that could
236 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
237 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000238 strings corresponding to subnormal values, (3) a memory leak for
239 some values large enough to cause overflow, and (4) a number of
240 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000241
Benjamin Petersonaea44282010-01-04 01:10:28 +0000242- The __complex__ method is now looked up on the class of instances to make it

253 described in C99 Annex F.
254
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000255- Issue #1811: improve accuracy and cross-platform consistency for
256 true division of integers: the result of a/b is now correctly
257 rounded for ints a and b (at least on IEEE 754 platforms), and in
258 particular does not depend on the internal representation of an int.
259
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000260- Issue #6834: replace the implementation for the 'python' and 'pythonw'
261 executables on OSX.
262
263 These executables now work properly with the arch(1) command:
264 ``arch -ppc python`` will start a universal binary version of python
265 in PPC mode (unlike previous releases).
266
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000267- Issue #7466: segmentation fault when the garbage collector is called

283
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000284- Issue #7298: fixes for range and reversed(range(...)). Iteration
285 over range(a, b, c) incorrectly gave an empty iterator when a, b and
286 c fit in C long but the length of the range did not. Also fix
287 several cases where reversed(range(a, b, c)) gave wrong results, and
288 fix a refleak for reversed(range(a, b, c)) with large arguments.
289
Raymond Hettingerfc438512009-11-01 20:55:33 +0000290- Issue #7244: itertools.izip_longest() no longer ignores exceptions

416 has '\0' at the end.
417
Mark Dickinsonde604012010-01-01 19:27:32 +0000418- Issue #5080: The argument parsing functions PyArg_ParseTuple,
419 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
420 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a

492 Decimal-to-float comparisons; all comparisons involving numeric
493 types (bool, int, float, complex, Decimal, Fraction) should now
494 act as expected.

Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000609- Issue #8573: asyncore _strerror() function might throw ValueError.
610
Victor Stinnere125f132010-05-15 21:04:43 +0000611- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
612 error messages when accessing undefined class attributes because of the cheap
613 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000614 The cheap inheritance has been deprecated.
615
Tarek Ziadéae4d5c62010-05-05 22:27:31 +0000616- Issue #4265: shutil.copyfile() was leaking file descriptors when disk fills.
617 Patch by Tres Seaver.
618
Victor Stinnerde629d42010-05-05 21:43:57 +0000619- Issue #8390: tarfile uses surrogateespace as the default error handler
620 (instead of replace in read mode or strict in write mode)
621
Barry Warsaw83d89982010-05-05 16:18:31 +0000622- Issue #7755: Use an unencumbered audio file for tests.
623
Ronald Oussorenac764d32010-05-05 15:32:33 +0000624- Issue #8621: uuid.uuid4() returned the same sequence of values in the
625 parent and any children created using ``os.fork`` on MacOS X 10.6.
626
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000627- Issue #8567: Fix precedence of signals in Decimal module: when a
628 Decimal operation raises multiple signals and more than one of those
629 signals is trapped, the specification determines the order in which
630 the signals should be handled. In many cases this order wasn't
631 being followed, leading to the wrong Python exception being raised.
632
Antoine Pitrou6be88762010-05-03 16:48:20 +0000633- Issue #7865: The close() method of :mod:`io` objects should not swallow
634 exceptions raised by the implicit flush(). Also ensure that calling
635 close() several times is supported. Patch by Pascal Chambon.
636
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000637- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
638 gc.DEBUG_STATS.
639
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000640- Issue #8354: The siginterrupt setting is now preserved for all signals,
641 not just SIGCHLD.
642
Georg Brandl25106ce2010-05-21 21:49:47 +0000643- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000644 webbrowser.get("safari").
645
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000646- Issue #8464: tarfile no longer creates files with execute permissions set
647 when mode="w|" is used.
648
Antoine Pitroubf043492010-04-29 10:11:46 +0000649- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
650 of the Linux kernel. Patch by Yaniv Aknin.
651
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000652- Issue #8295: Added shutil.unpack_archive.
653
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000654- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
655 It should correctly return an empty response now.
656
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000657- Issue #8546: Reject None given as the buffering argument to _pyio.open.
658
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000659- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
660 Sridhar Ratnakumar.
661
R. David Murrayad78d152010-04-27 02:45:53 +0000662- Issue #6656: fix locale.format_string to handle escaped percents
663 and mappings.
664
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000665- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
666 where the method could block indefinitely if called just before the
667 event loop started running. This also fixes the occasional freezes
668 witnessed in test_httpservers.
669
Antoine Pitrou40f08742010-04-24 22:04:40 +0000670- Issue #8524: When creating an SSL socket, the timeout value of the
671 original socket wasn't retained (instead, a socket with a positive timeout
672 would be turned into a non-blocking SSL socket).
673
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000674- Issue #5103: SSL handshake would ignore the socket timeout and block
675 indefinitely if the other end didn't respond.
676
677- The do_handshake() method of SSL objects now adjusts the blocking mode of
678 the SSL structure if necessary (as other methods already do).
679
Victor Stinner13bb71c2010-04-23 21:41:56 +0000680- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
681 and bytes strings for environment keys and values
682
Victor Stinner4d078042010-04-23 19:28:32 +0000683- Issue #8467: Pure Python implementation of subprocess encodes the error
684 message using surrogatepass error handler to support surrogates in the
685 message
686
Victor Stinner349fd522010-04-23 10:56:17 +0000687- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
688
Sean Reifscheider13daf122010-04-23 09:29:52 +0000689- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
690 the string "python" as the *ident*. openlog() arguments are all optional
691 and keywords.
692
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000693- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
694 a non-infinite timeout. Also make that method friendlier with applications
695 wanting to continue using the socket in clear-text mode, by disabling
696 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
697
Antoine Pitrou7062db82010-04-22 13:30:10 +0000698- Issue #8496: make mailcap.lookup() always return a list, rather than an
699 iterator. Patch by Gregory Nofi.
700
Victor Stinner35466c52010-04-22 11:23:23 +0000701- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
702 collation name contains a surrogate character.
703
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000704- Issue #8484: Load all ciphers and digest algorithms when initializing
705 the _ssl extension, such that verification of some SSL certificates
706 doesn't fail because of an "unknown algorithm".
707
Tarek Ziadéfb437512010-04-20 08:57:33 +0000708- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
709
Victor Stinnere125f132010-05-15 21:04:43 +0000710- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000711 shutil.copytree.
712
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000713- Issue #4814: timeout parameter is now applied also for connections resulting
714 from PORT/EPRT commands.
715
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000716- Issue #8463: added missing reference to bztar in shutil's documentation.
717
Ronald Oussoren84151202010-04-18 20:46:11 +0000718- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
719 (as long as the user didn't specify 'automatic proxy configuration').
720
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000721- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
722 code as stated in RFC-959 at chapter 5.4.
723
Victor Stinner738446f02010-04-18 00:00:44 +0000724- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
725 surrogates.
726
Antoine Pitrou0454af92010-04-17 23:51:58 +0000727- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000728 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000729
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000730- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
731 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
732
Victor Stinner0e59cc32010-04-16 23:49:32 +0000733- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
734 the current working directory.
735
Victor Stinner5bfe1462010-04-16 13:28:05 +0000736- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
737 using backslashreplace error handler
738
Victor Stinnercfa72782010-04-16 11:45:13 +0000739- Issue #8412: os.system() now accepts bytes, bytearray and str with

741
Senthil Kumaranad02d232010-04-16 03:02:13 +0000742- Issue #2987: RFC2732 support for urlparse (IPv6 addresses). Patch by Tony
743 Locke and Hans Ulrich Niedermann.
744
R. David Murrayd48739f2010-04-14 18:59:18 +0000745- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
746
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000747- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
748 module now takes an optional timeout argument in seconds. Timeout support
749 relies on the system threading library, so as to avoid a semi-busy wait
750 loop.
751
Victor Stinner485fb562010-04-13 11:07:24 +0000752- Issue #8383: pickle and pickletools use surrogatepass error handler when
753 encoding unicode as utf8 to support lone surrogates and stay compatible with
754 Python 2.x and 3.0
755
R. David Murrayb2416e52010-04-12 16:58:02 +0000756- Issue #7585: difflib context and unified diffs now place a tab between
757 filename and date, conforming to the 'standards' they were originally
758 designed to follow. This improves compatibility with patch tools.
759
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000760- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
761 character sets will now consistently use a Content-Transfer-Encoding of
762 7bit rather than sometimes being marked as 8bit.
763
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000764- Issue #8375: test_distutils now checks if the temporary directory are still
765 present before it cleans them.
766
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000767- Issue #8374: Update the internal alias table in the :mod:`locale` module
768 to cover recent locale changes and additions.
769
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000770- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
771 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
772 and `ssl.OPENSSL_VERSION_NUMBER`.
773
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000774- Add functools.total_ordering() and functools.cmp_to_key().
775
Mark Dickinson089b00c2010-04-03 15:51:03 +0000776- Issue #8257: The Decimal construct now accepts a float instance
777 directly, converting that float to a Decimal of equal value:
778
779 >>> Decimal(1.1)
780 Decimal('1.100000000000000088817841970012523233890533447265625')
781
Mark Dickinson98127c32010-04-03 11:18:52 +0000782- Issue #8294: The Fraction constructor now accepts Decimal and float
783 instances directly.
784
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000785- Issue #7279: Comparisons involving a Decimal signaling NaN now
786 signal InvalidOperation instead of returning False. (Comparisons
787 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
788 are now hashable; Decimal signaling NaNs remain unhashable.
789
790- Issue #2531: Comparison operations between floats and Decimal
791 instances now return a result based on the numeric values of the
792 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000793 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000794 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000795
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000796- Added a subtract() method to collections.Counter().
797
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000798- Issue #8233: When run as a script, py_compile.py optionally takes a single
799 argument `-` which tells it to read files to compile from stdin. Each line
800 is read on demand and the named file is compiled immediately. (Original
801 patch by Piotr Ożarowski).
802
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000803- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
804 form feed (0x0C) are now considered linebreaks, as specified in Unicode
805 Standard Annex #14. See issue #7643.
806 http://www.unicode.org/reports/tr14/
807
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000808- Comparisons using one of <, <=, >, >= between a complex instance and
809 a Fractions instance now raise TypeError instead of returning
810 True/False. This makes Fraction <=> complex comparisons consistent with
811 int <=> complex, float <=> complex, and complex <=> complex comparisons.
812
Antoine Pitrou39b35432010-03-23 00:25:54 +0000813- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
814 some methods (such as oss_mixer_device.fileno()) were not available.
815 Initial patch by Bertrand Janin.
816
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000817- Issue #8205: Remove the "Modules" directory from sys.path when Python is
818 running from the build directory (POSIX only).
819
Antoine Pitrou910bd512010-03-22 20:11:09 +0000820- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
821 didn't support chflags() (for example ZFS under FreeBSD). The error is
822 now silenced.
823
R. David Murrayca2edce2010-03-22 17:48:48 +0000824- Issue #7860: platform.uname now reports the correct 'machine' type
825 when Python is running in WOW64 mode on 64 bit Windows.
826
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000827- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
828 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
829 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000830
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000831- Issue #4282: Fix the main function of the profile module for a non-ASCII
832 script, open the file in binary mode and not in text mode with the default
833 (utf8) encoding.
834
Florent Xicluna54467e02010-03-21 12:29:50 +0000835- Issue #8179: Fix macpath.realpath() on a non-existing path.
836
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000837- Issue #8024: Update the Unicode database to 5.2.
838
Benjamin Peterson00888932010-03-18 22:37:38 +0000839- Issue #8168: py_compile now handles files with utf-8 BOMS.
840
Benjamin Peterson689a5582010-03-18 22:29:52 +0000841- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
842 detected.
843
Martin v. Löwis4b003072010-03-16 13:19:21 +0000844- Issue #6716/2: Backslash-replace error output in compilall.
845
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000846- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
847 with Tcl/Tk-8.5.
848
Matthias Klosec33b9022010-03-16 00:36:26 +0000849- Issue #8140: extend compileall to compile single files. Add -i option.
850
Matthias Klose82f60912010-03-15 13:46:04 +0000851- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
852 the locale.
853
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000854- The internals of the subprocess module on POSIX systems have been replaced
855 by an extension module (_posixsubprocess) so that the fork()+exec() can be
856 done safely without the possibility of deadlock in multithreaded applications.
857
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000858- subprocess.Popen now has restore_signals and start_new_session features.
859 The default of restore_signals=True is a new behavior compared to earlier
860 Python versions. This means that signals such as SIGPIPE are not ignored
861 by default in subprocesses launched by Python (Issue #1652).
862
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000863- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
864 cElementTree module is updated too.
865
Victor Stinnerb33062c2010-03-12 14:27:16 +0000866- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to
867 an non existent program name and Python is unable to retrieve the real
868 program name

873 the replacement were all bytes. Patch by Antoine Pitrou.
874
Gerhard Häringf9cee222010-03-05 15:20:03 +0000875- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
876 bugs and allows loading SQLite extensions from shared libraries.
877
Ezio Melottida227042010-03-14 11:51:00 +0000878- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Victor Stinnercee3ae82010-03-04 00:29:24 +0000881- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
882 reset also the pointer to the current pointer context.
883
Lars Gustäbel01385812010-03-03 12:08:54 +0000884- Issue #7232: Add support for the context manager protocol to the TarFile

894
Vinay Sajipdb81c4c2010-02-25 23:13:06 +0000895- Issue #7869: logging: improved diagnostic for format-time errors.

923 exception of canonical and is_canonical) now accept instances of int
924 and long wherever a Decimal instance is accepted, and implicitly

949 file position when calling `truncate()`. It would previously change the
950 file position to the given argument, which goes against the tradition of
951 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

957 It also solves an issue where interleaved calls to `read()` and
958 `readline()` give wrong results. Patch by Nir Aides.

1122 to execute file paths that refer to source or compiled Python files as well
1123 as zipfiles, directories and other valid sys.path entries that contain a
1124 __main__.py file. This allows applications that run other Python scripts to
1125 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001144 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001145 recursive locks as fast as regular non-recursive locks (previously,
1146 they were slower by 10x to 15x).

1304 relation to other methods required by the ABCs.
1305
Brett Cannon64ef00f2009-07-20 03:19:18 +00001306- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001355- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1356 10,000. Prior to this change, timezone adjustment in utctimetuple()
1357 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1358 raised in these edge cases.
1359
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001360- Issue #6641: The ``datetime.strptime`` method now supports the
1361 ``%z`` directive. When the ``%z`` directive is present in the
1362 format string, an aware ``datetime`` object is returned with
1363 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1364 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1365 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1366 without ``%z`` is discarded.
1367
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001368- Issue #5094: The ``datetime`` module now has a simple concrete class
1369 implementing ``datetime.tzinfo`` interface. Instances of the new
1370 class, ``datetime.timezone``, return fixed name and UTC offset from
1371 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1372 method always returns ``None``. A class attribute, ``utc`` contains
1373 an instance representing the UTC timezone. Original patch by Rafe
1374 Kaplan.
1375
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001376- Issue #8973: Add __all__ to struct module; this ensures that

1378
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001379- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001380 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001381 ``struct.error`` to be raised. Patch by Caleb Deveraux.

1385 is not safe to load both the readline and curses modules in an application.
1386

1389
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001390- Issue #8692: Optimize math.factorial: replace the previous naive
1391 algorithm with an improved 'binary-split' algorithm that uses fewer
1392 multiplications and allows many of the multiplications to be
1393 performed using plain C integer arithmetic instead of PyLong
1394 arithmetic. Also uses a lookup table for small arguments.
1395
Mark Dickinson85eacea2010-05-10 16:27:45 +00001396- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1397 overflow checks in the audioop module.
1398
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001399- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1400 calculating with integer arithmetic instead of float arithmetic internally):
1401 the result is now always correctly rounded, and is equivalent to td /
1402 timedelta(seconds=1).
1403
Mark Dickinson7c186e22010-04-20 22:32:49 +00001404- Issue #2706: Allow division of a timedelta by another timedelta:

1409
Mark Dickinsonc5935772010-04-03 15:54:36 +00001410- Issue #8300: When passing a non-integer argument to struct.pack with any
1411 integer format code, struct.pack first attempts to convert the non-integer
1412 using its __index__ method. If that method is non-existent or raises
1413 TypeError it goes on to try the __int__ method, as described below.
1414

1663 calling methods on the object.
1664
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001665- Issue #7222: Make thread "reaping" more reliable so that reference
1666 leak-chasing test runs give sensible results. The previous method of
1667 reaping threads could return successfully while some Thread objects were
1668 still referenced. This also introduces a new private function:
1669 :func:`_thread._count()`.
1670
R. David Murray27144602009-10-19 15:26:16 +00001671- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1672 longer runs the risk of causing the worker thread to fail.
1673
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001674- Issue #7055: test___all__ now greedily detects all modules which have an
1675 __all__ attribute, rather than using a hardcoded and incomplete list.

1678 runtest_inner in regrtest, with warnings if the called test modifies them,
1679 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001680
Mark Dickinson2e304402009-10-04 18:43:54 +00001681- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1682
Brett Cannon3c273842009-07-20 00:14:29 +00001683- Fixed tests in importlib.test.source.test_abc_loader that were masking
1684 the proper exceptions that should be raised for missing or improper code
1685 object bytecode.
1686
Brett Cannonb49c70c2009-07-15 04:08:33 +00001687- Removed importlib's custom test discovery code and switched to
1688 unittest.TestLoader.discover().

1877
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001878- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1879 than an int, which makes some operations possible under 64-bit Linux (e.g.

Mark Dickinson865e01a2009-05-07 16:37:01 +00001960- Issue #5914: Add new C API function PyOS_string_to_double, and
1961 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1962
Eric Smith741191f2009-05-06 13:08:15 +00001963- Issue #3382: float.__format__, complex.__format__, and %-formatting
1964 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1965 affects nan -> NAN and inf -> INF.

1969 a PendingDeprecation warning.
1970
Eric Smith63376222009-05-05 14:04:18 +00001971- Issue #5920: For float.__format__, change the behavior with the
1972 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1973 to be like 'g' but with at least one decimal point and with a
1974 default precision of 12. Previously, the behavior the same but with
1975 a default precision of 6. This more closely matches str(), and
1976 reduces surprises when adding alignment flags to the empty
1977 presentation type. This also affects the new complex.__format__ in
1978 the same way.
1979
Martin v. Löwis011e8422009-05-05 04:43:17 +00001980- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

1983 shadowed by classtype's, even if it was None. property now
1984 inserts the __doc__ into the subclass instance __dict__.
1985

1988
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001989- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001991- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1992 received a new method, detach(). detach() disconnects the underlying stream
1993 from the buffer or text IO and returns it.
1994
Mark Dickinson33841c32009-05-01 15:37:04 +00001995- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1996 floats with absolute value over 1e50. Also remove length
1997 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1998 12.34 no longer raise an exception.

2004 never gives more than the requested number of significant digits.
2005
Eric Smith6dc46f52009-04-27 20:39:49 +00002006- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

Mark Dickinsonad476da2009-04-23 19:14:16 +00002016- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2017 z involves nans, infs or negative zeros.
2018
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002019- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002020
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002021- Issue #1869 (and many duplicates): make round(x, n) correctly
2022 rounded for a float x, by using the decimal <-> binary conversions
2023 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2024 consistently agrees with format(x, '.2f').
2025
Benjamin Petersonae937c02009-04-18 20:54:08 +00002026- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

2032 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002033
2034- Implement PEP 378, Format Specifier for Thousands Separator, for
2035 floats.

Mark Dickinson3370cce2009-04-17 22:40:53 +00002037- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002038 1e11, not 1e12. This avoids printing 13 significant digits in
2039 situations where only 12 of them are correct. Example problem
2040 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2041 long time.)
2042
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002043- Issue #1580: On most platforms, use a 'short' float repr: for a
2044 finite float x, repr(x) now outputs a string based on the shortest
2045 sequence of decimal digits that rounds to x. Previous behaviour was
2046 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002047 Another minor difference is that the new repr switches to
2048 exponential notation at 1e16 instead of the previous 1e17; this
2049 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002050
2051 There's a new sys attribute sys.float_repr_style, which takes
2052 the value 'short' to indicate that we're using short float repr,
2053 and 'legacy' if the short float repr isn't available for one
2054 reason or another.
2055
2056 The float repr change involves incorporating David Gay's 'perfect
2057 rounding' code into the Python core (it's in Python/dtoa.c). As a
2058 secondary consequence, all string-to-float and float-to-string
2059 conversions (including all float formatting operations) will be
2060 correctly rounded on these platforms.
2061
2062 See issue 1580 discussions for details of platforms for which
2063 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002065- Issue #5759: float() didn't call __float__ on str subclasses.
2066
Georg Brandlabc38772009-04-12 15:51:51 +00002067- The string.maketrans() function is deprecated; there is a new static method
2068 maketrans() on the bytes and bytearray classes. This removes confusion about
2069 the types string.maketrans() is supposed to work with, and mirrors the
2070 methods available on the str class.

2360
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002361- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2362 rotating the object pointer by 4 bits to the right.
2363
Mark Dickinson87ec0852009-02-09 17:15:59 +00002364- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2365 it now forces its argument to double before testing for infinity.

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002376
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002377- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002378 were suppressing all exceptions. These include list() and bytearray().

2382
Antoine Pitroub52ec782009-01-25 16:34:23 +00002383- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2384 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2385 evaluation loop is compiled with a new dispatch mechanism which gives
2386 speedups of up to 20%, depending on the system, on various benchmarks.
2387
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002388- Issue #4874: Most builtin decoders now reject unicode input.

2394
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002395- Issue #4838: When a module is deallocated, free the memory backing the
2396 optional module state data.
2397
Mark Dickinson8055afd2009-01-17 10:04:45 +00002398- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2399 type to (void *).
2400
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002401- Issue #4935: The overflow checking code in the expandtabs() method common
2402 to str, bytes and bytearray could be optimized away by the compiler, letting
2403 the interpreter segfault instead of raising an error.
2404
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002405- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2406 __next__ method.
2407
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002408- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2409 function no longer attempt to call the __long__ slot to convert an object
2410 to an integer. Only the __int__ and __trunc__ slots are examined.
2411
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002412- Issue #4893: Use NT threading on CE.
2413

2415
Antoine Pitrouab868312009-01-10 15:40:25 +00002416- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2417 common cases are optimized thanks to a dedicated fast path and a moderate
2418 amount of loop unrolling.
2419
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002420- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2421 collecting the oldest generation) so that allocating lots of objects without
2422 destroying them does not show quadratic performance. Based on a proposal by
2423 Martin von Löwis at
2424 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2425
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002426- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002427 having been closed (for instance, a read() call could return some
2428 previously buffered data). Patch by Dmitry Vasiliev.
2429
Antoine Pitrou05608432009-01-09 18:53:14 +00002430- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2431 flag to work properly. Furthermore, when specifying -u, the text stdout
2432 and stderr streams have line-by-line buffering enabled (the default being
2433 to buffer arbitrary chunks of data).
2434
Raymond Hettinger35631532009-01-09 03:58:09 +00002435- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2436 instead of ints (reducing its size from 4 to 8 times thereby reducing
2437 Python's overall memory).
2438
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002439- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2440 an existing .py counterpart, override the co_filename attributes of all
2441 code objects if the original filename is obsolete (which can happen if the
2442 file has been renamed, moved, or if it is accessed through different paths).
2443 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2444
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002445- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2446 one byte. Also fixes the meaning of len() so that it returns the number of
2447 items, rather than the size in bytes.
2448
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002449- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2450
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002451- Issue #4747: When the terminal does not use utf-8, executing a script with
2452 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2453
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002454- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002455 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002456
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002457- Issue #3680: Reference cycles created through a dict, set or deque iterator
2458 did not get collected.
2459
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002460- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2461 where the tp_hash and tp_dict slots are both NULL.
2462
Georg Brandlccc47b62008-12-28 11:44:14 +00002463- Issue #4759: None is now allowed as the first argument of
2464 bytearray.translate(). It was always allowed for bytes.translate().
2465
Skip Montanaro80072cb2008-12-23 03:51:14 +00002466- Added test case to ensure attempts to read from a file opened for writing
2467 fail.
2468
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002469- Issue #3106: Speedup some comparisons (str/str and int/int).

2473
Antoine Pitrou621601a2008-12-17 23:18:19 +00002474- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2475 print elapsed times, not only when some objects are uncollectable /
2476 unreachable. Original patch by Neil Schemenauer.
2477
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002478- Issue #3439: Add a bit_length method to int.
2479
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002480- Issue #2173: When getting device encoding, check that return value of
2481 nl_langinfo is not the empty string. This was causing silent build
2482 failures on OS X.
2483
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002484- Issue #4597: Fixed several opcodes that weren't always propagating
2485 exceptions.
2486
2487- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002488 context manager returns a value that cannot be converted to a bool.
2489
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002490- Issue #4445: Replace "sizeof(PyBytesObject)" with
2491 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2492 bytes instances. On a typical machine this saves 3 bytes of memory
2493 (on average) per allocation of a bytes instance.
2494
Christian Heimesa872de52008-12-05 08:26:55 +00002495- Issue #4533: File read operation was dreadfully slow due to a slowly
2496 growing read buffer. Fixed by using the same growth rate algorithm as
2497 Python 2.x.
2498
Antoine Pitrou5504e892008-12-06 21:27:53 +00002499- Issue #4509: Various issues surrounding resize of bytearray objects to
2500 which there are buffer exports (e.g. memoryview instances).
2501
Georg Brandlf9734072008-12-07 15:30:06 +00002502- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2503 method on file objects with closefd=False. The file descriptor is still
2504 kept open but the file object behaves like a closed file. The ``FileIO``
2505 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002506
Antoine Pitroubc420402008-12-07 20:14:49 +00002507- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2513
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002514- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2515 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2516 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2517 of using the replace error handler in PyUnicode_DecodeUTF8().
