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

651 subprocess.Popen() and os._execvpe() support bytes program name. Add
652 os.supports_bytes_environ flag: True if the native OS type of the environment
653 is bytes (eg. False on Windows).
654
Lars Gustäbel1465cc22010-05-17 18:02:50 +0000655- Issue #8633: tarfile is now able to read and write archives with "raw" binary

Victor Stinner84ae1182010-05-06 22:05:07 +0000691
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000692- Issue #8573: asyncore _strerror() function might throw ValueError.
693
Victor Stinnere125f132010-05-15 21:04:43 +0000694- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
695 error messages when accessing undefined class attributes because of the cheap
696 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000697 The cheap inheritance has been deprecated.
698

709
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000710- Issue #8567: Fix precedence of signals in Decimal module: when a
711 Decimal operation raises multiple signals and more than one of those
712 signals is trapped, the specification determines the order in which
713 the signals should be handled. In many cases this order wasn't
714 being followed, leading to the wrong Python exception being raised.
715
Antoine Pitrou6be88762010-05-03 16:48:20 +0000716- Issue #7865: The close() method of :mod:`io` objects should not swallow

722
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000723- Issue #8354: The siginterrupt setting is now preserved for all signals,
724 not just SIGCHLD.
725
Georg Brandl25106ce2010-05-21 21:49:47 +0000726- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does

744
R. David Murrayad78d152010-04-27 02:45:53 +0000745- Issue #6656: fix locale.format_string to handle escaped percents
746 and mappings.
747
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000748- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
749 where the method could block indefinitely if called just before the
750 event loop started running. This also fixes the occasional freezes
751 witnessed in test_httpservers.
752
Antoine Pitrou40f08742010-04-24 22:04:40 +0000753- Issue #8524: When creating an SSL socket, the timeout value of the
754 original socket wasn't retained (instead, a socket with a positive timeout
755 would be turned into a non-blocking SSL socket).
756
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000757- Issue #5103: SSL handshake would ignore the socket timeout and block
758 indefinitely if the other end didn't respond.
759
760- The do_handshake() method of SSL objects now adjusts the blocking mode of
761 the SSL structure if necessary (as other methods already do).
762
Victor Stinner13bb71c2010-04-23 21:41:56 +0000763- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
764 and bytes strings for environment keys and values
765
Victor Stinner4d078042010-04-23 19:28:32 +0000766- Issue #8467: Pure Python implementation of subprocess encodes the error

771
Sean Reifscheider13daf122010-04-23 09:29:52 +0000772- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
773 the string "python" as the *ident*. openlog() arguments are all optional
774 and keywords.
775
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000776- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
777 a non-infinite timeout. Also make that method friendlier with applications
778 wanting to continue using the socket in clear-text mode, by disabling
779 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
780
Antoine Pitrou7062db82010-04-22 13:30:10 +0000781- Issue #8496: make mailcap.lookup() always return a list, rather than an
782 iterator. Patch by Gregory Nofi.
783
Victor Stinner35466c52010-04-22 11:23:23 +0000784- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
785 collation name contains a surrogate character.
786
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000787- Issue #8484: Load all ciphers and digest algorithms when initializing
788 the _ssl extension, such that verification of some SSL certificates
789 doesn't fail because of an "unknown algorithm".
790
Tarek Ziadéfb437512010-04-20 08:57:33 +0000791- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
792
Victor Stinnere125f132010-05-15 21:04:43 +0000793- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000794 shutil.copytree.
795
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000796- Issue #4814: timeout parameter is now applied also for connections resulting
797 from PORT/EPRT commands.
798
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000799- Issue #8463: added missing reference to bztar in shutil's documentation.
800
Ronald Oussoren84151202010-04-18 20:46:11 +0000801- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
802 (as long as the user didn't specify 'automatic proxy configuration').
803
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000804- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
805 code as stated in RFC-959 at chapter 5.4.
806
Victor Stinner738446f02010-04-18 00:00:44 +0000807- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
808 surrogates.
809
Antoine Pitrou0454af92010-04-17 23:51:58 +0000810- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000811 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

814 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
815
Victor Stinner0e59cc32010-04-16 23:49:32 +0000816- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
817 the current working directory.
818
Victor Stinner5bfe1462010-04-16 13:28:05 +0000819- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
820 using backslashreplace error handler

829
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000830- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
831 module now takes an optional timeout argument in seconds. Timeout support
832 relies on the system threading library, so as to avoid a semi-busy wait
833 loop.
834
Victor Stinner485fb562010-04-13 11:07:24 +0000835- Issue #8383: pickle and pickletools use surrogatepass error handler when
836 encoding unicode as utf8 to support lone surrogates and stay compatible with
837 Python 2.x and 3.0
838
R. David Murrayb2416e52010-04-12 16:58:02 +0000839- Issue #7585: difflib context and unified diffs now place a tab between
840 filename and date, conforming to the 'standards' they were originally
841 designed to follow. This improves compatibility with patch tools.
842
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000843- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
844 character sets will now consistently use a Content-Transfer-Encoding of
845 7bit rather than sometimes being marked as 8bit.
846
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000847- Issue #8375: test_distutils now checks if the temporary directory are still
848 present before it cleans them.
849
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000850- Issue #8374: Update the internal alias table in the :mod:`locale` module
851 to cover recent locale changes and additions.
852
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000853- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
854 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
855 and `ssl.OPENSSL_VERSION_NUMBER`.
856
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000857- Add functools.total_ordering() and functools.cmp_to_key().
858
Mark Dickinson089b00c2010-04-03 15:51:03 +0000859- Issue #8257: The Decimal construct now accepts a float instance
860 directly, converting that float to a Decimal of equal value:
861
862 >>> Decimal(1.1)
863 Decimal('1.100000000000000088817841970012523233890533447265625')
864
Mark Dickinson98127c32010-04-03 11:18:52 +0000865- Issue #8294: The Fraction constructor now accepts Decimal and float
866 instances directly.
867
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000868- Issue #7279: Comparisons involving a Decimal signaling NaN now
869 signal InvalidOperation instead of returning False. (Comparisons
870 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
871 are now hashable; Decimal signaling NaNs remain unhashable.
872
873- Issue #2531: Comparison operations between floats and Decimal
874 instances now return a result based on the numeric values of the
875 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000876 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000877 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000878
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000879- Added a subtract() method to collections.Counter().
880
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000881- Issue #8233: When run as a script, py_compile.py optionally takes a single
882 argument `-` which tells it to read files to compile from stdin. Each line
883 is read on demand and the named file is compiled immediately. (Original
884 patch by Piotr Ożarowski).
885
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000886- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
887 form feed (0x0C) are now considered linebreaks, as specified in Unicode
888 Standard Annex #14. See issue #7643.
889 http://www.unicode.org/reports/tr14/
890
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000891- Comparisons using one of <, <=, >, >= between a complex instance and
892 a Fractions instance now raise TypeError instead of returning
893 True/False. This makes Fraction <=> complex comparisons consistent with
894 int <=> complex, float <=> complex, and complex <=> complex comparisons.
895
Antoine Pitrou39b35432010-03-23 00:25:54 +0000896- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

1203
Nick Coghlan260bd3e2009-11-16 06:49:25 +00001204- Issue #6816: runpy now provides a run_path function that allows Python code
1205 to execute file paths that refer to source or compiled Python files as well
1206 as zipfiles, directories and other valid sys.path entries that contain a
1207 __main__.py file. This allows applications that run other Python scripts to
1208 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001227 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001228 recursive locks as fast as regular non-recursive locks (previously,
1229 they were slower by 10x to 15x).

1247
Gregory P. Smith50467882009-11-01 18:42:17 +00001248- Issue #7246 & Issue #7208: getpass now properly flushes input before
1249 reading from stdin so that existing input does not confuse it and
1250 lead to incorrect entry or an IOError. It also properly flushes it
1251 afterwards to avoid the terminal echoing the input afterwards on
1252 OSes such as Solaris.
1253
Mark Dickinsona2d1fe02009-10-29 12:23:02 +00001254- Issue #7233: Fix a number of two-argument Decimal methods to make

1476 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1477 method always returns ``None``. A class attribute, ``utc`` contains
1478 an instance representing the UTC timezone. Original patch by Rafe
1479 Kaplan.

1746 with no arguments, doctest.py now gives a usage message.
1747
R. David Murrayef1992b2009-12-16 15:19:27 +00001748- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
1749
R. David Murray596da442009-12-14 23:06:11 +00001750- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +00001751 instead of a hardcoded port number in test_rapid_restart.
1752
Victor Stinnere125f132010-05-15 21:04:43 +00001753- Issue #7431: use TESTFN in test_linecache instead of trying to create a
R. David Murrayba311052009-12-04 00:09:14 +00001754 file in the Lib/test directory, which might be read-only for the
1755 user running the tests.
1756
R. David Murray35768ad2009-11-15 00:23:21 +00001757- Issue #7324: add a sanity check to regrtest argument parsing to
1758 catch the case of an option with no handler.
1759
R. David Murray7dc72cc2009-11-14 16:13:02 +00001760- Issue #7312: Add a -F flag to run the selected tests in a loop until
1761 a test fails. Can be combined with -j.
1762
Antoine Pitrou060cee22009-11-13 16:29:04 +00001763- Issue #6551: test_zipimport could import and then destroy some modules of
1764 the encodings package, which would make other tests fail further down
1765 the road because the internally cached encoders and decoders would point
1766 to empty global variables.
1767
Antoine Pitrou941ee882009-11-11 20:59:38 +00001768- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1779 calling methods on the object.
1780
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001781- Issue #7222: Make thread "reaping" more reliable so that reference
1782 leak-chasing test runs give sensible results. The previous method of
1783 reaping threads could return successfully while some Thread objects were
1784 still referenced. This also introduces a new private function:
1785 :func:`_thread._count()`.
1786
R. David Murray27144602009-10-19 15:26:16 +00001787- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1788 longer runs the risk of causing the worker thread to fail.
1789
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001790- Issue #7055: test___all__ now greedily detects all modules which have an
1791 __all__ attribute, rather than using a hardcoded and incomplete list.

1795 and a new section in the summary report at the end.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00002068What's New in Python 3.1 beta 1?
2069================================
2070
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00002071*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00002072
2073Core and Builtins
2074-----------------
2075
Mark Dickinson865e01a2009-05-07 16:37:01 +00002076- Issue #5914: Add new C API function PyOS_string_to_double, and
2077 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2078
Eric Smith741191f2009-05-06 13:08:15 +00002079- Issue #3382: float.__format__, complex.__format__, and %-formatting
2080 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2081 affects nan -> NAN and inf -> INF.
2082
Mark Hammond5a607a32009-05-06 08:04:54 +00002083- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2084 in all operations, including splitdrive, split, etc. splitunc() now issues
2085 a PendingDeprecation warning.
2086
Eric Smith63376222009-05-05 14:04:18 +00002087- Issue #5920: For float.__format__, change the behavior with the
2088 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2089 to be like 'g' but with at least one decimal point and with a
2090 default precision of 12. Previously, the behavior the same but with
2091 a default precision of 6. This more closely matches str(), and
2092 reduces surprises when adding alignment flags to the empty
2093 presentation type. This also affects the new complex.__format__ in
2094 the same way.
2095
Martin v. Löwis011e8422009-05-05 04:43:17 +00002096- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2097
R. David Murrayb18500d2009-05-04 22:59:07 +00002098- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2099 shadowed by classtype's, even if it was None. property now
2100 inserts the __doc__ into the subclass instance __dict__.
2101
Antoine Pitrou244651a2009-05-04 18:56:13 +00002102- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2103 sequences. Patch by Nick Barnes and Victor Stinner.
2104
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002105- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002106
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002107- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2108 received a new method, detach(). detach() disconnects the underlying stream
2109 from the buffer or text IO and returns it.
2110
Mark Dickinson33841c32009-05-01 15:37:04 +00002111- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2112 floats with absolute value over 1e50. Also remove length
2113 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2114 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002115
Eric Smith741191f2009-05-06 13:08:15 +00002116- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002117 format(complex(1, 2./3), '.5') now produces a sensible result.
2118
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002119- Issue #5864: Fix empty format code formatting for floats so that it
2120 never gives more than the requested number of significant digits.
2121
Eric Smith6dc46f52009-04-27 20:39:49 +00002122- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2123 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2124
Eric Smithcc32a112009-04-26 21:35:14 +00002125- Issue #5835: Deprecate PyOS_ascii_formatd.
2126
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002127- Issue #4971: Fix titlecase for characters that are their own
2128 titlecase, but not their own uppercase.
2129
Benjamin Peterson193152c2009-04-25 01:08:45 +00002130- Issue #5283: Setting __class__ in __del__ caused a segfault.
2131
Mark Dickinsonad476da2009-04-23 19:14:16 +00002132- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2133 z involves nans, infs or negative zeros.
2134
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002135- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002136
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002137- Issue #1869 (and many duplicates): make round(x, n) correctly
2138 rounded for a float x, by using the decimal <-> binary conversions
2139 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2140 consistently agrees with format(x, '.2f').
2141
Benjamin Petersonae937c02009-04-18 20:54:08 +00002142- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2143 some builtin types.
2144
Eric Smith0923d1d2009-04-16 20:16:10 +00002145- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2146
Eric Smith35e84722009-04-16 20:21:28 +00002147- Issue #5515: str.format() type 'n' combined with commas and leading
2148 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002149
2150- Implement PEP 378, Format Specifier for Thousands Separator, for
2151 floats.
2152
Mark Dickinson3370cce2009-04-17 22:40:53 +00002153- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002154 1e11, not 1e12. This avoids printing 13 significant digits in
2155 situations where only 12 of them are correct. Example problem
2156 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2157 long time.)
2158
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002159- Issue #1580: On most platforms, use a 'short' float repr: for a
2160 finite float x, repr(x) now outputs a string based on the shortest
2161 sequence of decimal digits that rounds to x. Previous behaviour was
2162 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002163 Another minor difference is that the new repr switches to
2164 exponential notation at 1e16 instead of the previous 1e17; this
2165 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002166
2167 There's a new sys attribute sys.float_repr_style, which takes
2168 the value 'short' to indicate that we're using short float repr,
2169 and 'legacy' if the short float repr isn't available for one
2170 reason or another.
2171
2172 The float repr change involves incorporating David Gay's 'perfect
2173 rounding' code into the Python core (it's in Python/dtoa.c). As a
2174 secondary consequence, all string-to-float and float-to-string
2175 conversions (including all float formatting operations) will be
2176 correctly rounded on these platforms.
2177
2178 See issue 1580 discussions for details of platforms for which
2179 this change does not apply.
2180
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002181- Issue #5759: float() didn't call __float__ on str subclasses.
2182
Georg Brandlabc38772009-04-12 15:51:51 +00002183- The string.maketrans() function is deprecated; there is a new static method
2184 maketrans() on the bytes and bytearray classes. This removes confusion about
2185 the types string.maketrans() is supposed to work with, and mirrors the
2186 methods available on the str class.
2187
R. David Murraydc6da8a2009-04-09 22:16:43 +00002188- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2189 its clarity and its speed.
2190
Matthias Klose091c7b12009-04-07 13:24:27 +00002191- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2192 to avoid compiler warnings.
2193
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002194- Issue #3739: The unicode-internal encoder now reports the number of characters
2195 consumed like any other encoder (instead of the number of bytes).

Brett Cannon0759dd62009-04-01 18:13:07 +00002340- Issue #1665206: Remove the last eager import in _warnings.c and make it lazy.
2341
Georg Brandlab6f2f62009-03-31 04:16:10 +00002342- Fix a segfault when running test_exceptions with coverage, caused by
2343 insufficient checks in accessors of Exception.__context__.
2344
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002345- Issue #5604: non-ASCII characters in module name passed to
2346 imp.find_module() were converted to UTF-8 while the path is
2347 converted to the default filesystem encoding, causing nonsense.
2348
Benjamin Peterson09832742009-03-26 17:15:46 +00002349- Issue #5126: str.isprintable() returned False for space characters.

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +00002351- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
2352 the end sys.path, for compatibility with the system install of Python.
2353
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002354- Issue #4688: Add a heuristic so that tuples and dicts containing only
2355 untrackable objects are not tracked by the garbage collector. This can
2356 reduce the size of collections and therefore the garbage collection overhead
2357 on long-running programs, depending on their particular use of datatypes.
2358
Mark Dickinson17e4fdd2009-03-23 18:44:57 +00002359- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
2360 improve its performance. Long divisions and remainder operations
2361 are now between 50% and 150% faster.
2362
Mark Dickinsonbd792642009-03-18 20:06:12 +00002363- Issue #4258: Make it possible to use base 2**30 instead of base
2364 2**15 for the internal representation of integers, for performance
2365 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2366 --enable-big-digits option to configure, which overrides the
2367 default. Add sys.int_info structseq to provide information about
2368 the internal format.
2369
Mark Dickinson081dfee2009-03-18 14:47:41 +00002370- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2371 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2372 and sizeof(Py_UNICODE) == 2.
2373
Eric Smith8ec90442009-03-14 12:29:34 +00002374- Issue #5237: Allow auto-numbered fields in str.format(). For
2375 example: '{} {}'.format(1, 2) == '1 2'.
2376
Antoine Pitrou652e7072009-03-13 19:25:20 +00002377- Issue #5392: when a very low recursion limit was set, the interpreter would
2378 abort with a fatal error after the recursion limit was hit twice.
2379
Matthias Klose042f1332009-04-04 14:32:42 +00002380- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

2426
Lars Gustäbel42e00912009-03-22 20:34:29 +00002427- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2428 forever on incomplete input. That caused tarfile.open() to hang when used
2429 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002451 struct.error instead of returning b'\xff\xff\xff\xff'. The
2452 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

Mark Dickinson87ec0852009-02-09 17:15:59 +00002480- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2481 it now forces its argument to double before testing for infinity.
2482
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002483- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2484 returns a non-number type.
2485
Benjamin Peterson87618552009-02-08 15:00:52 +00002486- Issue #5182: Removed memoryview.__str__.

2491 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002492
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002493- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002494 were suppressing all exceptions. These include list() and bytearray().
2495
Mark Dickinson1124e712009-01-28 21:25:58 +00002496- Issue #4707: round(x, n) now returns an integer if x is an integer.
2497 Previously it returned a float.
2498
Antoine Pitroub52ec782009-01-25 16:34:23 +00002499- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2500 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2501 evaluation loop is compiled with a new dispatch mechanism which gives
2502 speedups of up to 20%, depending on the system, on various benchmarks.
2503
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002504- Issue #4874: Most builtin decoders now reject unicode input.

2510
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002511- Issue #4838: When a module is deallocated, free the memory backing the
2512 optional module state data.
2513
Mark Dickinson8055afd2009-01-17 10:04:45 +00002514- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2515 type to (void *).
2516
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002517- Issue #4935: The overflow checking code in the expandtabs() method common
2518 to str, bytes and bytearray could be optimized away by the compiler, letting
2519 the interpreter segfault instead of raising an error.
2520
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002521- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2522 __next__ method.
2523
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002524- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API

2531
Antoine Pitrouab868312009-01-10 15:40:25 +00002532- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2533 common cases are optimized thanks to a dedicated fast path and a moderate
2534 amount of loop unrolling.
2535
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002536- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2537 collecting the oldest generation) so that allocating lots of objects without
2538 destroying them does not show quadratic performance. Based on a proposal by
2539 Martin von Löwis at
2540 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2541
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002542- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002543 having been closed (for instance, a read() call could return some
2544 previously buffered data). Patch by Dmitry Vasiliev.
2545
Antoine Pitrou05608432009-01-09 18:53:14 +00002546- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2547 flag to work properly. Furthermore, when specifying -u, the text stdout
2548 and stderr streams have line-by-line buffering enabled (the default being
2549 to buffer arbitrary chunks of data).
2550
Raymond Hettinger35631532009-01-09 03:58:09 +00002551- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2552 instead of ints (reducing its size from 4 to 8 times thereby reducing
2553 Python's overall memory).
2554
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002555- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2556 an existing .py counterpart, override the co_filename attributes of all
2557 code objects if the original filename is obsolete (which can happen if the
2558 file has been renamed, moved, or if it is accessed through different paths).
2559 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2560
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002561- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2562 one byte. Also fixes the meaning of len() so that it returns the number of
2563 items, rather than the size in bytes.
2564
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002565- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2566
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002567- Issue #4747: When the terminal does not use utf-8, executing a script with
2568 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2569
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002570- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002571 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002572
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002573- Issue #3680: Reference cycles created through a dict, set or deque iterator
2574 did not get collected.
2575
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002576- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2577 where the tp_hash and tp_dict slots are both NULL.
2578
Georg Brandlccc47b62008-12-28 11:44:14 +00002579- Issue #4759: None is now allowed as the first argument of
2580 bytearray.translate(). It was always allowed for bytes.translate().
2581
Skip Montanaro80072cb2008-12-23 03:51:14 +00002582- Added test case to ensure attempts to read from a file opened for writing
2583 fail.
2584
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002585- Issue #3106: Speedup some comparisons (str/str and int/int).

2588 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2589
Antoine Pitrou621601a2008-12-17 23:18:19 +00002590- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2591 print elapsed times, not only when some objects are uncollectable /
2592 unreachable. Original patch by Neil Schemenauer.
2593
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002594- Issue #3439: Add a bit_length method to int.
2595
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002596- Issue #2173: When getting device encoding, check that return value of
2597 nl_langinfo is not the empty string. This was causing silent build
2598 failures on OS X.
2599
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002600- Issue #4597: Fixed several opcodes that weren't always propagating
2601 exceptions.
2602
2603- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002604 context manager returns a value that cannot be converted to a bool.
2605
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002606- Issue #4445: Replace "sizeof(PyBytesObject)" with
2607 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2608 bytes instances. On a typical machine this saves 3 bytes of memory
2609 (on average) per allocation of a bytes instance.
2610
Christian Heimesa872de52008-12-05 08:26:55 +00002611- Issue #4533: File read operation was dreadfully slow due to a slowly
2612 growing read buffer. Fixed by using the same growth rate algorithm as
2613 Python 2.x.
2614
Antoine Pitrou5504e892008-12-06 21:27:53 +00002615- Issue #4509: Various issues surrounding resize of bytearray objects to
2616 which there are buffer exports (e.g. memoryview instances).
2617
Georg Brandlf9734072008-12-07 15:30:06 +00002618- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2619 method on file objects with closefd=False. The file descriptor is still
2620 kept open but the file object behaves like a closed file. The ``FileIO``

2954 do an explicit seek to the end of file (so that e.g. tell() returns the

3201 supporting objects as input no matter how it was compiled (built in
3202 implementations or external openssl library).
3203
Mark Dickinson29500f62009-01-15 15:36:10 +00003204- Issue #4397: Fix occasional test_socket failure on OS X.

3207
Antoine Pitroubcd5cbe2009-01-08 21:17:16 +00003208- Issue #4751: hashlib now releases the GIL when hashing large buffers
3209 (with a hardwired threshold of 2048 bytes), allowing better parallelization
3210 on multi-CPU systems. Contributed by Lukas Lueg (ebfe) and Victor Stinner.
3211
Martin v. Löwis5c88d812009-01-02 20:47:48 +00003212- Issue #4051: Prevent conflict of UNICODE macros in cPickle.
3213
Antoine Pitrou31f30b12009-01-02 17:34:35 +00003214- Issue #4738: Each zlib object now has a separate lock, allowing to compress
3215 or decompress several streams at once on multi-CPU systems. Also, the GIL
3216 is now released when computing the CRC of a large buffer. Patch by ebfe.
3217
Georg Brandlb1441c72009-01-03 22:33:39 +00003218- Issue #4228: Pack negative values the same way as 2.4 in struct's L format.
3219

3223 OpenBSD.
Amaury Forgeot d'Arcefae8c42008-11-21 23:08:09 +00003224
Antoine Pitrou3ad3a0d2008-12-18 17:08:32 +00003225- Issue #4583: array.array would not always prohibit resizing when a buffer
3226 has been exported, resulting in an interpreter crash when accessing the
3227 buffer.
3228
Martin v. Löwis841edad2008-11-30 10:36:49 +00003229
Jack Diederiche0cbd692009-04-01 04:27:09 +00003230- Issue #5228: Make functools.partial objects can now be pickled.

3234
Antoine Pitrou88909542009-06-29 13:54:42 +00003235- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3236 regression tests in parallel, shortening the total runtime.
3237
Guilherme Polo2a998fa2009-06-21 17:40:07 +00003238- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3239 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
3240 the same behaviour as test_ttkguionly (and now also test_tk) which is to
3241 skip the tests if DISPLAY is defined but can't be used.
3242
R. David Murraya21e4ca2009-03-31 23:16:50 +00003243- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003244 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003245 from test support, which does the conversion.
3246
Guilherme Polo9de29af2009-01-28 20:40:48 +00003247- Issue #5083: New 'gui' resource for regrtest.
