10*Release date: XX-XXX-XXX*
11
12Core and Builtins
13-----------------
14
Antoine Pitrou1ac745b2010-07-11 12:12:00 +000015- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
16 compiler.
17
Benjamin Petersonccabcd42010-07-07 20:54:01 +000018- Issue #8413: structsequence now subclasses tuple.
19
Ezio Melotti57221d02010-07-01 07:32:02 +000020- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
21 start byte and the continuation byte(s) are now considered invalid, instead
22 of the number of bytes specified by the start byte.
23 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
24 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
25 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
26 Previous versions returned a single u'\ufffd'.
27
Mark Dickinson50b79a82010-06-30 11:13:36 +000028- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real
29 part -0.0 rather than 0.0. So "-7j" is now exactly equivalent to
30 "-(7j)".
31
Benjamin Peterson88968ad2010-06-25 19:30:21 +000032- Be more specific in error messages about positional arguments.
33
Victor Stinner4aae1eb2010-06-24 22:08:25 +000034- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
35 objects, as described in the documentation.
36
Victor Stinner0fe25a42010-06-17 23:08:50 +000037- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000038 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
39 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000040
Mark Dickinsond35a32e2010-06-17 12:33:22 +000041- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
42 compilation code dealing with unary minus applied to a constant.
43 The removed code was mutating the ST, causing a second compilation
44 to fail.
45
Victor Stinner554f3f02010-06-16 23:33:54 +000046- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
47 mode raises unicode errors. The encoder only supports "strict" and "replace"
48 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000049 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000050
Victor Stinner25e8ec42010-06-25 00:02:38 +000051- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
52 "w*" format instead. Add tests for "w*" format.
53
Victor Stinner06e49dd2010-06-13 18:21:50 +000054- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
55 formats if the string contains a null byte/character. Write unit tests for
56 string formats.
57
Nick Coghlan5e76e942010-06-12 13:42:46 +000058- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
59 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
60 location of the raised exception.
61
Victor Stinner313a1202010-06-11 23:56:51 +000062- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
63 filenames and enable os.fsencode().
64
Benjamin Peterson285a6892010-06-22 19:21:52 +000065- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
66
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000067- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
68 the interpreter with characters outside the Basic Multilingual Plane
69 (higher than 0x10000).
70
Mark Dickinsonc7301312010-06-10 16:05:10 +000071- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
72 raise TypeError instead of giving a DeprecationWarning when a float
73 is parsed using the 'L' code (for long long). (All other integer
74 codes already raise TypeError in this case.)
75
Victor Stinner600d3be2010-06-10 12:00:55 +000076- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
77 enable shortcuts for upper case encoding name. Add also a shortcut for
78 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
79
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000080- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
81 doesn't support "char buffer" anymore in Python3.
82
83- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
84 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
85 like bytearray.
86
Victor Stinner33109a12010-05-28 21:55:10 +000087- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
88 used anymore and it was never documented.
89
Benjamin Peterson95304522010-06-08 14:57:22 +000090- In the str.format(), raise a ValueError when indexes to arguments are too
91 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000092
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000093- Issue #2844: Make int('42', n) consistently raise ValueError for
94 invalid integers n (including n = -909).
95
Mark Dickinsondc787d22010-05-23 13:33:13 +000096- Issue #8188: Introduce a new scheme for computing hashes of numbers
97 (instances of int, float, complex, decimal.Decimal and
98 fractions.Fraction) that makes it easy to maintain the invariant
99 that hash(x) == hash(y) whenever x and y have equal value.
100
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000101- Issue #8748: Fix two issues with comparisons between complex and integer
102 objects. (1) The comparison could incorrectly return True in some cases
103 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
104 (2) The comparison raised an OverflowError for large integers, leading
105 to unpredictable exceptions when combining integers and complex objects
106 in sets or dicts.
107
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000108- Issue #8766: Initialize _warnings module before importing the first module.
109 Fix a crash if an empty directory called "encodings" exists in sys.path.
110
Victor Stinner9ca9c252010-05-19 16:53:30 +0000111- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
112 encoding and surrogateespace error handler instead of the locale encoding to
113 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
114
Victor Stinner372ac5e2010-05-17 01:26:01 +0000115- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
116 (instead of strict) error handler to escape surrogates
117
Victor Stinnerae6265f2010-05-15 16:27:27 +0000118- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
119 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000120 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
121 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000122
Victor Stinner59e62db2010-05-15 13:14:32 +0000123- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
124 error handler, not only the default error handler (strict)
125
Victor Stinnerb744ba12010-05-15 12:27:16 +0000126- Issue #8610: Load file system codec at startup, and display a fatal error on
127 failure. Set the file system encoding to utf-8 (instead of None) if getting
128 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
129
Victor Stinner0964ee12010-04-30 16:48:45 +0000130- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
131 PyUnicode_FromString() to support surrogates in the filename and use the
132 right encoding
133
Georg Brandl8569e582010-05-19 20:57:08 +0000134- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
135
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000136- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
137
Benjamin Petersonfb886362010-04-24 18:21:17 +0000138- Issue #8419: Prevent the dict constructor from accepting non-string keyword
139 arguments.
140
Victor Stinner14284c22010-04-23 12:02:30 +0000141- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
142 indirectly Python signal handlers anymore because mywrite() ignores
143 exceptions (KeyboardInterrupt)
144
Victor Stinner31be90b2010-04-22 19:38:16 +0000145- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
146 unicode string (eg. backslashreplace)
147
Victor Stinnerdcb24032010-04-22 12:08:36 +0000148- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
149 you have to convert your bytearray filenames to bytes
150
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000151- Issue #7332: Remove the 16KB stack-based buffer in
152 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
153 benefit compared to the dynamic memory allocation fallback. Patch by
154 Charles-François Natali.
155
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000156- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
157 passed to bytes or bytearray.
158
Philip Jenvey0805ca32010-04-07 04:04:10 +0000159- Issue #7301: Add environment variable $PYTHONWARNINGS.
160
Benjamin Petersond856ab62010-04-06 21:55:16 +0000161- Issue #8329: Don't return the same lists from select.select when no fds are
162 changed.
163
Mark Dickinson3318d292010-04-06 16:53:17 +0000164- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
165 on 64-bit machines. The shift count for either left or right shift is
166 permitted to be up to sys.maxsize.
167
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000168- Ensure that tokenization of identifiers is not affected by locale.

175 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000176
Victor Stinner120c2122010-03-25 00:30:28 +0000177- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
178 is unknown
179

181
Mark Dickinsond59b4162010-03-13 11:34:40 +0000182- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
183 PyMemberDefs could produce an internal error; raise TypeError instead.
184
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000185- Issue #7845: Rich comparison methods on the complex type now return
186 NotImplemented rather than raising a TypeError when comparing with an
187 incompatible type; this allows user-defined classes to implement their own
188 comparisons with complex.
189
Victor Stinner52f6dd72010-03-12 14:45:56 +0000190- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
191 (SIGINT). If an error occurs while importing the site module, the error is
192 printed and Python exits. Initialize the GIL before importing the site
193 module.
194
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000195- Issue #7173: Generator finalization could invalidate sys.exc_info().

198 a fatal error in low memory condition.
199
Victor Stinner6aa278e2010-03-03 00:18:49 +0000200- Issue #7820: The parser tokenizer restores all bytes in the right if
201 the BOM check fails.
202
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000203- Handle errors from looking up __prepare__ correctly.
204
Larry Hastings1373a072010-02-24 22:49:58 +0000205- Issue #5939: Add additional runtime checking to ensure a valid capsule
206 in Modules/_ctypes/callproc.c.
207

210 strings.
211
Eric Smithabb28c62010-02-23 00:22:24 +0000212- Issue #6902: Fix problem with built-in types format incorrectly with

221 deprecations.
222
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000223- Issue #7385: Fix a crash in `MemoryView_FromObject` when
224 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
225
Mark Dickinsonbc099642010-01-29 17:27:24 +0000226- Issue #7788: Fix an interpreter crash produced by deleting a list
227 slice with very large step value.
228
Eric Smithf7bb5782010-01-27 00:44:57 +0000229- Issue #7766: Change sys.getwindowsversion() return value to a named
230 tuple and add the additional members returned in an OSVERSIONINFOEX
231 structure. The new members are service_pack_major, service_pack_minor,
232 suite_mask, and product_type.
233
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000234- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
235 could crash in many places because of the PyByteArray_AS_STRING() macro
236 returning NULL. The macro now returns a statically allocated empty
237 string instead.
238
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000239- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
240 where the right hand operand is a set of constants, by turning the set into
241 a frozenset and pre-building it as a constant. The comparison operation
242 is made against the constant instead of building a new set each time it is
243 executed (a similar optimization already existed which turned a list of
244 constants into a pre-built tuple). Patch and additional tests by Dave
245 Malcolm.
246
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000247- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
248 methods of bytes, bytearray and unicode objects by using a common
249 implementation based on stringlib's fast search. Patch by Florent Xicluna.
250
Mark Dickinson45b63652010-01-16 18:10:25 +0000251- Issue #7632: Fix various str -> float conversion bugs present in 2.7
252 alpha 2, including: (1) a serious 'wrong output' bug that could
253 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
254 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000255 strings corresponding to subnormal values, (3) a memory leak for
256 some values large enough to cause overflow, and (4) a number of
257 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000258
Benjamin Petersonaea44282010-01-04 01:10:28 +0000259- The __complex__ method is now looked up on the class of instances to make it
260 consistent with other special methods.

269 negative zero) in ** operator. The behaviour now conforms to that
270 described in C99 Annex F.
271
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000272- Issue #1811: improve accuracy and cross-platform consistency for
273 true division of integers: the result of a/b is now correctly
274 rounded for ints a and b (at least on IEEE 754 platforms), and in
275 particular does not depend on the internal representation of an int.
276
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000277- Issue #6834: replace the implementation for the 'python' and 'pythonw'
278 executables on OSX.
279
280 These executables now work properly with the arch(1) command:
281 ``arch -ppc python`` will start a universal binary version of python
282 in PPC mode (unlike previous releases).
283
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000284- Issue #7466: segmentation fault when the garbage collector is called
285 in the middle of populating a tuple. Patch by Florent Xicluna.
286
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +0000287- Issue #7419: setlocale() could crash the interpreter on Windows when called
288 with invalid values.
289
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000290- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
291 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
292
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000293- Issue #7085: Fix crash when importing some extensions in a thread

300
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000301- Issue #7298: fixes for range and reversed(range(...)). Iteration
302 over range(a, b, c) incorrectly gave an empty iterator when a, b and
303 c fit in C long but the length of the range did not. Also fix
304 several cases where reversed(range(a, b, c)) gave wrong results, and
305 fix a refleak for reversed(range(a, b, c)) with large arguments.
306
Raymond Hettingerfc438512009-11-01 20:55:33 +0000307- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitroub5218772010-05-21 09:56:06 +0000628 several ``OP_*`` constants to the `ssl` module. This allows to selectively
629 disable protocol versions, when used in combination with `PROTOCOL_SSLv23`.

634 compilation in a non-ASCII directory if stdout encoding is ASCII (eg. if
635 stdout is not a TTY).
636
Victor Stinnerb745a742010-05-18 17:17:23 +0000637- Issue #8513: os.get_exec_path() supports b'PATH' key and bytes value.
638 subprocess.Popen() and os._execvpe() support bytes program name. Add
639 os.supports_bytes_environ flag: True if the native OS type of the environment
640 is bytes (eg. False on Windows).
641
Lars Gustäbel1465cc22010-05-17 18:02:50 +0000642- Issue #8633: tarfile is now able to read and write archives with "raw" binary

672 objects.
673
Benjamin Peterson225168e2010-05-06 22:29:53 +0000674- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
675 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
676 file system encoding with the surrogateescape error handler (instead of
677 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

680
Victor Stinnere125f132010-05-15 21:04:43 +0000681- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
682 error messages when accessing undefined class attributes because of the cheap
683 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000684 The cheap inheritance has been deprecated.

696
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000697- Issue #8567: Fix precedence of signals in Decimal module: when a
698 Decimal operation raises multiple signals and more than one of those
699 signals is trapped, the specification determines the order in which
700 the signals should be handled. In many cases this order wasn't
701 being followed, leading to the wrong Python exception being raised.
702
Antoine Pitrou6be88762010-05-03 16:48:20 +0000703- Issue #7865: The close() method of :mod:`io` objects should not swallow

709
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000710- Issue #8354: The siginterrupt setting is now preserved for all signals,
711 not just SIGCHLD.
712
Georg Brandl25106ce2010-05-21 21:49:47 +0000713- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does

R. David Murrayad78d152010-04-27 02:45:53 +0000732- Issue #6656: fix locale.format_string to handle escaped percents
733 and mappings.
734
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000735- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
736 where the method could block indefinitely if called just before the
737 event loop started running. This also fixes the occasional freezes
738 witnessed in test_httpservers.
739
Antoine Pitrou40f08742010-04-24 22:04:40 +0000740- Issue #8524: When creating an SSL socket, the timeout value of the
741 original socket wasn't retained (instead, a socket with a positive timeout
742 would be turned into a non-blocking SSL socket).
743
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000744- Issue #5103: SSL handshake would ignore the socket timeout and block
745 indefinitely if the other end didn't respond.
746
747- The do_handshake() method of SSL objects now adjusts the blocking mode of
748 the SSL structure if necessary (as other methods already do).
749
Victor Stinner13bb71c2010-04-23 21:41:56 +0000750- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
751 and bytes strings for environment keys and values
752
Victor Stinner4d078042010-04-23 19:28:32 +0000753- Issue #8467: Pure Python implementation of subprocess encodes the error

758
Sean Reifscheider13daf122010-04-23 09:29:52 +0000759- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
760 the string "python" as the *ident*. openlog() arguments are all optional
761 and keywords.
762
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000763- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
764 a non-infinite timeout. Also make that method friendlier with applications
765 wanting to continue using the socket in clear-text mode, by disabling
766 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
767
Antoine Pitrou7062db82010-04-22 13:30:10 +0000768- Issue #8496: make mailcap.lookup() always return a list, rather than an
769 iterator. Patch by Gregory Nofi.

772 collation name contains a surrogate character.
773
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000774- Issue #8484: Load all ciphers and digest algorithms when initializing
775 the _ssl extension, such that verification of some SSL certificates
776 doesn't fail because of an "unknown algorithm".
777
Tarek Ziadéfb437512010-04-20 08:57:33 +0000778- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
779
Victor Stinnere125f132010-05-15 21:04:43 +0000780- Issue #1540112: Now allowing the choice of a copy function in

782
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000783- Issue #4814: timeout parameter is now applied also for connections resulting
784 from PORT/EPRT commands.
785
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000786- Issue #8463: added missing reference to bztar in shutil's documentation.
787
Ronald Oussoren84151202010-04-18 20:46:11 +0000788- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
789 (as long as the user didn't specify 'automatic proxy configuration').
790
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000791- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
792 code as stated in RFC-959 at chapter 5.4.
793
Victor Stinner738446f02010-04-18 00:00:44 +0000794- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
795 surrogates.
796
Antoine Pitrou0454af92010-04-17 23:51:58 +0000797- Issue #850728: Add a *timeout* parameter to the `acquire()` method of

802
Victor Stinner0e59cc32010-04-16 23:49:32 +0000803- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
804 the current working directory.
805

816
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000817- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
818 module now takes an optional timeout argument in seconds. Timeout support
819 relies on the system threading library, so as to avoid a semi-busy wait
820 loop.
821
Victor Stinner485fb562010-04-13 11:07:24 +0000822- Issue #8383: pickle and pickletools use surrogatepass error handler when

824 Python 2.x and 3.0
825
R. David Murrayb2416e52010-04-12 16:58:02 +0000826- Issue #7585: difflib context and unified diffs now place a tab between
827 filename and date, conforming to the 'standards' they were originally
828 designed to follow. This improves compatibility with patch tools.
829
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000830- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
831 character sets will now consistently use a Content-Transfer-Encoding of
832 7bit rather than sometimes being marked as 8bit.
833
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000834- Issue #8375: test_distutils now checks if the temporary directory are still
835 present before it cleans them.
836
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000837- Issue #8374: Update the internal alias table in the :mod:`locale` module
838 to cover recent locale changes and additions.
839
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000840- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
841 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
842 and `ssl.OPENSSL_VERSION_NUMBER`.
843
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000844- Add functools.total_ordering() and functools.cmp_to_key().
845
Mark Dickinson089b00c2010-04-03 15:51:03 +0000846- Issue #8257: The Decimal construct now accepts a float instance
847 directly, converting that float to a Decimal of equal value:
848
849 >>> Decimal(1.1)
850 Decimal('1.100000000000000088817841970012523233890533447265625')
851
Mark Dickinson98127c32010-04-03 11:18:52 +0000852- Issue #8294: The Fraction constructor now accepts Decimal and float
853 instances directly.
854
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000855- Issue #7279: Comparisons involving a Decimal signaling NaN now
856 signal InvalidOperation instead of returning False. (Comparisons
857 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
858 are now hashable; Decimal signaling NaNs remain unhashable.
859
860- Issue #2531: Comparison operations between floats and Decimal
861 instances now return a result based on the numeric values of the
862 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000863 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000864 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000865
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000866- Added a subtract() method to collections.Counter().
867
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000868- Issue #8233: When run as a script, py_compile.py optionally takes a single
869 argument `-` which tells it to read files to compile from stdin. Each line
870 is read on demand and the named file is compiled immediately. (Original
871 patch by Piotr Ożarowski).
872
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000873- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
874 form feed (0x0C) are now considered linebreaks, as specified in Unicode
875 Standard Annex #14. See issue #7643.
876 http://www.unicode.org/reports/tr14/
877
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000878- Comparisons using one of <, <=, >, >= between a complex instance and
879 a Fractions instance now raise TypeError instead of returning
880 True/False. This makes Fraction <=> complex comparisons consistent with
881 int <=> complex, float <=> complex, and complex <=> complex comparisons.
882
Antoine Pitrou39b35432010-03-23 00:25:54 +0000883- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

892 now silenced.
893
R. David Murrayca2edce2010-03-22 17:48:48 +0000894- Issue #7860: platform.uname now reports the correct 'machine' type
895 when Python is running in WOW64 mode on 64 bit Windows.
896

1192 to execute file paths that refer to source or compiled Python files as well
1193 as zipfiles, directories and other valid sys.path entries that contain a
1194 __main__.py file. This allows applications that run other Python scripts to
1195 support the same flexibility as the CPython command line itself.
1196
Antoine Pitrou45d61a32009-11-13 22:35:18 +00001197- Issue #7318: multiprocessing now uses a timeout when it fails to establish
1198 a connection with another process, rather than looping endlessly. The
1199 default timeout is 20 seconds, which should be amply sufficient for
1200 local connections.
1201
Antoine Pitrouc63ecee2009-11-10 21:34:48 +00001202- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and
1203 unpickled. This fixes crashes under Windows when trying to run
1204 test_multiprocessing in verbose mode.
1205
Michael Foord34c94622010-02-10 15:51:42 +00001206- Issue #7893: ``unittest.TextTestResult`` is made public and a ``resultclass``
1207 argument added to the TextTestRunner constructor allowing a different result
1208 class to be used without having to subclass.

1212
Antoine Pitrou434736a2009-11-10 18:46:01 +00001213- Issue #3001: Add a C implementation of recursive locks which is used by
Victor Stinnere125f132010-05-15 21:04:43 +00001214 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001215 recursive locks as fast as regular non-recursive locks (previously,
1216 they were slower by 10x to 15x).
1217
Antoine Pitroub0872682009-11-09 16:08:16 +00001218- Issue #7282: Fix a memory leak when an RLock was used in a thread other
1219 than those started through `threading.Thread` (for example, using
1220 `_thread.start_new_thread()`).
1221
Brett Cannone52c9192009-11-07 23:55:05 +00001222- Issue #7187: Importlib would not silence the IOError raised when trying to

1229 objects on 64-bit systems. Patch by Michael Broghton.
1230
Antoine Pitrou03f13442009-11-02 11:36:51 +00001231- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
1232 a modification is done through it. This fixes inconsistencies and test
1233 failures on systems with slightly bogus mtime behaviour.
1234
Gregory P. Smith50467882009-11-01 18:42:17 +00001235- Issue #7246 & Issue #7208: getpass now properly flushes input before
1236 reading from stdin so that existing input does not confuse it and
1237 lead to incorrect entry or an IOError. It also properly flushes it
1238 afterwards to avoid the terminal echoing the input afterwards on
1239 OSes such as Solaris.
1240
Mark Dickinsona2d1fe02009-10-29 12:23:02 +00001241- Issue #7233: Fix a number of two-argument Decimal methods to make

Brett Cannon69194272009-07-20 04:23:48 +00001371- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
1372 loaders that allow for modules to be executed. Both importlib.abc.PyLoader
1373 and PyPycLoader inherit from this class and provide implementations in
1374 relation to other methods required by the ABCs.
1375
Brett Cannon64ef00f2009-07-20 03:19:18 +00001376- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001439- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1440 10,000. Prior to this change, timezone adjustment in utctimetuple()
1441 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1442 raised in these edge cases.
1443
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001444- Issue #6641: The ``datetime.strptime`` method now supports the
1445 ``%z`` directive. When the ``%z`` directive is present in the
1446 format string, an aware ``datetime`` object is returned with
1447 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1448 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1449 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1450 without ``%z`` is discarded.
1451
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001452- Issue #5094: The ``datetime`` module now has a simple concrete class
1453 implementing ``datetime.tzinfo`` interface. Instances of the new
1454 class, ``datetime.timezone``, return fixed name and UTC offset from
1455 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1456 method always returns ``None``. A class attribute, ``utc`` contains
1457 an instance representing the UTC timezone. Original patch by Rafe
1458 Kaplan.

1475 algorithm with an improved 'binary-split' algorithm that uses fewer
1476 multiplications and allows many of the multiplications to be
1477 performed using plain C integer arithmetic instead of PyLong
1478 arithmetic. Also uses a lookup table for small arguments.

1759 leak-chasing test runs give sensible results. The previous method of
1760 reaping threads could return successfully while some Thread objects were
1761 still referenced. This also introduces a new private function:
1762 :func:`_thread._count()`.
1763
R. David Murray27144602009-10-19 15:26:16 +00001764- Issue #7151: fixed regrtest -j so that output to stderr from a test no

Benjamin Petersonbd35b032009-04-04 23:16:41 +00002049
2050Core and Builtins
2051-----------------
2052
Mark Dickinson865e01a2009-05-07 16:37:01 +00002053- Issue #5914: Add new C API function PyOS_string_to_double, and
2054 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2055
Eric Smith741191f2009-05-06 13:08:15 +00002056- Issue #3382: float.__format__, complex.__format__, and %-formatting
2057 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2058 affects nan -> NAN and inf -> INF.
2059
Mark Hammond5a607a32009-05-06 08:04:54 +00002060- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2061 in all operations, including splitdrive, split, etc. splitunc() now issues
2062 a PendingDeprecation warning.
2063
Eric Smith63376222009-05-05 14:04:18 +00002064- Issue #5920: For float.__format__, change the behavior with the
2065 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2066 to be like 'g' but with at least one decimal point and with a
2067 default precision of 12. Previously, the behavior the same but with
2068 a default precision of 6. This more closely matches str(), and
2069 reduces surprises when adding alignment flags to the empty
2070 presentation type. This also affects the new complex.__format__ in
2071 the same way.
2072
Martin v. Löwis011e8422009-05-05 04:43:17 +00002073- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2074
R. David Murrayb18500d2009-05-04 22:59:07 +00002075- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2076 shadowed by classtype's, even if it was None. property now
2077 inserts the __doc__ into the subclass instance __dict__.
2078
Antoine Pitrou244651a2009-05-04 18:56:13 +00002079- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2080 sequences. Patch by Nick Barnes and Victor Stinner.
2081
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002082- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002083
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002084- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2085 received a new method, detach(). detach() disconnects the underlying stream
2086 from the buffer or text IO and returns it.
2087
Mark Dickinson33841c32009-05-01 15:37:04 +00002088- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2089 floats with absolute value over 1e50. Also remove length
2090 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2091 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002092
Eric Smith741191f2009-05-06 13:08:15 +00002093- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002094 format(complex(1, 2./3), '.5') now produces a sensible result.
2095
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002096- Issue #5864: Fix empty format code formatting for floats so that it
2097 never gives more than the requested number of significant digits.
2098
Eric Smith6dc46f52009-04-27 20:39:49 +00002099- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2100 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2101
Eric Smithcc32a112009-04-26 21:35:14 +00002102- Issue #5835: Deprecate PyOS_ascii_formatd.
2103
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002104- Issue #4971: Fix titlecase for characters that are their own
2105 titlecase, but not their own uppercase.
2106
Benjamin Peterson193152c2009-04-25 01:08:45 +00002107- Issue #5283: Setting __class__ in __del__ caused a segfault.
2108
Mark Dickinsonad476da2009-04-23 19:14:16 +00002109- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2110 z involves nans, infs or negative zeros.
2111
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002112- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002113
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002114- Issue #1869 (and many duplicates): make round(x, n) correctly
2115 rounded for a float x, by using the decimal <-> binary conversions
2116 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2117 consistently agrees with format(x, '.2f').
2118
Benjamin Petersonae937c02009-04-18 20:54:08 +00002119- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2120 some builtin types.
2121
Eric Smith0923d1d2009-04-16 20:16:10 +00002122- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2123
Eric Smith35e84722009-04-16 20:21:28 +00002124- Issue #5515: str.format() type 'n' combined with commas and leading
2125 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002126
2127- Implement PEP 378, Format Specifier for Thousands Separator, for
2128 floats.
2129
Mark Dickinson3370cce2009-04-17 22:40:53 +00002130- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002131 1e11, not 1e12. This avoids printing 13 significant digits in
2132 situations where only 12 of them are correct. Example problem
2133 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2134 long time.)
2135
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002136- Issue #1580: On most platforms, use a 'short' float repr: for a
2137 finite float x, repr(x) now outputs a string based on the shortest
2138 sequence of decimal digits that rounds to x. Previous behaviour was
2139 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002140 Another minor difference is that the new repr switches to
2141 exponential notation at 1e16 instead of the previous 1e17; this
2142 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002143
2144 There's a new sys attribute sys.float_repr_style, which takes
2145 the value 'short' to indicate that we're using short float repr,
2146 and 'legacy' if the short float repr isn't available for one
2147 reason or another.
2148
2149 The float repr change involves incorporating David Gay's 'perfect
2150 rounding' code into the Python core (it's in Python/dtoa.c). As a
2151 secondary consequence, all string-to-float and float-to-string
2152 conversions (including all float formatting operations) will be
2153 correctly rounded on these platforms.
2154
2155 See issue 1580 discussions for details of platforms for which
2156 this change does not apply.
2157
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002158- Issue #5759: float() didn't call __float__ on str subclasses.
2159
Georg Brandlabc38772009-04-12 15:51:51 +00002160- The string.maketrans() function is deprecated; there is a new static method
2161 maketrans() on the bytes and bytearray classes. This removes confusion about
2162 the types string.maketrans() is supposed to work with, and mirrors the
2163 methods available on the str class.
2164
R. David Murraydc6da8a2009-04-09 22:16:43 +00002165- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2166 its clarity and its speed.
2167
Matthias Klose091c7b12009-04-07 13:24:27 +00002168- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2169 to avoid compiler warnings.
2170
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002171- Issue #3739: The unicode-internal encoder now reports the number of characters
2172 consumed like any other encoder (instead of the number of bytes).
2173

2186
Raymond Hettingereb816952009-05-29 01:22:18 +00002187- Issue #5150: IDLE's format menu now has an option to strip trailing

2189
Vinay Sajipaffbd872009-06-11 10:11:47 +00002190- Issue #5940: distutils.command.build_clib.check_library_list was not doing

2253 results in a handle_expt_event call, not handle_read_event, and POLLERR
2254 and POLLNVAL now call handle_close, not handle_expt_event. Also,
2255 dispatcher now has an 'ignore_log_types' attribute for suppressing
2256 log messages, which is set to 'warning' by default.
2257

2320 insufficient checks in accessors of Exception.__context__.
2321
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002322- Issue #5604: non-ASCII characters in module name passed to
2323 imp.find_module() were converted to UTF-8 while the path is
2324 converted to the default filesystem encoding, causing nonsense.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002328- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2329 the end sys.path, for compatibility with the system install of Python.
2330
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002331- Issue #4688: Add a heuristic so that tuples and dicts containing only
2332 untrackable objects are not tracked by the garbage collector. This can
2333 reduce the size of collections and therefore the garbage collection overhead
2334 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002457- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2458 it now forces its argument to double before testing for infinity.
2459
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002460- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002469
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002470- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002471 were suppressing all exceptions. These include list() and bytearray().
2472
Mark Dickinson1124e712009-01-28 21:25:58 +00002473- Issue #4707: round(x, n) now returns an integer if x is an integer.
2474 Previously it returned a float.
2475
Antoine Pitroub52ec782009-01-25 16:34:23 +00002476- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2477 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2478 evaluation loop is compiled with a new dispatch mechanism which gives
2479 speedups of up to 20%, depending on the system, on various benchmarks.
2480

2489 optional module state data.
2490
Mark Dickinson8055afd2009-01-17 10:04:45 +00002491- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2492 type to (void *).
2493
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002494- Issue #4935: The overflow checking code in the expandtabs() method common
2495 to str, bytes and bytearray could be optimized away by the compiler, letting
2496 the interpreter segfault instead of raising an error.
2497
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002498- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2499 __next__ method.
2500
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002501- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2502 function no longer attempt to call the __long__ slot to convert an object
2503 to an integer. Only the __int__ and __trunc__ slots are examined.
2504
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002505- Issue #4893: Use NT threading on CE.

2508
Antoine Pitrouab868312009-01-10 15:40:25 +00002509- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2510 common cases are optimized thanks to a dedicated fast path and a moderate
2511 amount of loop unrolling.
2512
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002513- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2514 collecting the oldest generation) so that allocating lots of objects without
2515 destroying them does not show quadratic performance. Based on a proposal by
2516 Martin von Löwis at
2517 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2518
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002519- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002520 having been closed (for instance, a read() call could return some
2521 previously buffered data). Patch by Dmitry Vasiliev.
2522
Antoine Pitrou05608432009-01-09 18:53:14 +00002523- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2524 flag to work properly. Furthermore, when specifying -u, the text stdout
2525 and stderr streams have line-by-line buffering enabled (the default being
2526 to buffer arbitrary chunks of data).
2527
Raymond Hettinger35631532009-01-09 03:58:09 +00002528- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2529 instead of ints (reducing its size from 4 to 8 times thereby reducing
2530 Python's overall memory).
2531
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002532- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2533 an existing .py counterpart, override the co_filename attributes of all
2534 code objects if the original filename is obsolete (which can happen if the
2535 file has been renamed, moved, or if it is accessed through different paths).
2536 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2537
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002538- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2539 one byte. Also fixes the meaning of len() so that it returns the number of
2540 items, rather than the size in bytes.
2541
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002542- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2543
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002544- Issue #4747: When the terminal does not use utf-8, executing a script with
2545 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2546
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002547- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002548 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002549
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002550- Issue #3680: Reference cycles created through a dict, set or deque iterator
2551 did not get collected.
2552
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002553- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2554 where the tp_hash and tp_dict slots are both NULL.
2555
Georg Brandlccc47b62008-12-28 11:44:14 +00002556- Issue #4759: None is now allowed as the first argument of
2557 bytearray.translate(). It was always allowed for bytes.translate().
2558
Skip Montanaro80072cb2008-12-23 03:51:14 +00002559- Added test case to ensure attempts to read from a file opened for writing
2560 fail.

2569 unreachable. Original patch by Neil Schemenauer.
2570

2572
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002573- Issue #2173: When getting device encoding, check that return value of
2574 nl_langinfo is not the empty string. This was causing silent build
2575 failures on OS X.
2576
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002577- Issue #4597: Fixed several opcodes that weren't always propagating
2578 exceptions.

2580- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002581 context manager returns a value that cannot be converted to a bool.
2582
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002583- Issue #4445: Replace "sizeof(PyBytesObject)" with
2584 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2585 bytes instances. On a typical machine this saves 3 bytes of memory
2586 (on average) per allocation of a bytes instance.
2587
Christian Heimesa872de52008-12-05 08:26:55 +00002588- Issue #4533: File read operation was dreadfully slow due to a slowly
2589 growing read buffer. Fixed by using the same growth rate algorithm as
2590 Python 2.x.
2591
Antoine Pitrou5504e892008-12-06 21:27:53 +00002592- Issue #4509: Various issues surrounding resize of bytearray objects to
2593 which there are buffer exports (e.g. memoryview instances).
2594
Georg Brandlf9734072008-12-07 15:30:06 +00002595- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2596 method on file objects with closefd=False. The file descriptor is still
2597 kept open but the file object behaves like a closed file. The ``FileIO``
2598 object also got a new readonly attribute ``closefd``.

2608 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2609 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2610 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00003212- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3213 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00003215- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3216 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
3217 the same behaviour as test_ttkguionly (and now also test_tk) which is to
3218 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00003220- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003221 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003222 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00003224- Issue #5083: New 'gui' resource for regrtest.
