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

636 subprocess.Popen() and os._execvpe() support bytes program name. Add
637 os.supports_bytes_environ flag: True if the native OS type of the environment
638 is bytes (eg. False on Windows).
639

694
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000695- Issue #8567: Fix precedence of signals in Decimal module: when a
696 Decimal operation raises multiple signals and more than one of those
697 signals is trapped, the specification determines the order in which
698 the signals should be handled. In many cases this order wasn't
699 being followed, leading to the wrong Python exception being raised.

R. David Murrayad78d152010-04-27 02:45:53 +0000730- Issue #6656: fix locale.format_string to handle escaped percents
731 and mappings.
732
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000733- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
734 where the method could block indefinitely if called just before the
735 event loop started running. This also fixes the occasional freezes
736 witnessed in test_httpservers.
737
Antoine Pitrou40f08742010-04-24 22:04:40 +0000738- Issue #8524: When creating an SSL socket, the timeout value of the
739 original socket wasn't retained (instead, a socket with a positive timeout
740 would be turned into a non-blocking SSL socket).
741
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000742- Issue #5103: SSL handshake would ignore the socket timeout and block
743 indefinitely if the other end didn't respond.
744
745- The do_handshake() method of SSL objects now adjusts the blocking mode of
746 the SSL structure if necessary (as other methods already do).
747
Victor Stinner13bb71c2010-04-23 21:41:56 +0000748- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

Sean Reifscheider13daf122010-04-23 09:29:52 +0000757- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
758 the string "python" as the *ident*. openlog() arguments are all optional
759 and keywords.
760
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000761- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
762 a non-infinite timeout. Also make that method friendlier with applications
763 wanting to continue using the socket in clear-text mode, by disabling
764 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
765
Antoine Pitrou7062db82010-04-22 13:30:10 +0000766- Issue #8496: make mailcap.lookup() always return a list, rather than an

770 collation name contains a surrogate character.
771
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000772- Issue #8484: Load all ciphers and digest algorithms when initializing
773 the _ssl extension, such that verification of some SSL certificates
774 doesn't fail because of an "unknown algorithm".
775
Tarek Ziadéfb437512010-04-20 08:57:33 +0000776- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
777
Victor Stinnere125f132010-05-15 21:04:43 +0000778- Issue #1540112: Now allowing the choice of a copy function in

780
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000781- Issue #4814: timeout parameter is now applied also for connections resulting
782 from PORT/EPRT commands.
783
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000784- Issue #8463: added missing reference to bztar in shutil's documentation.
785
Ronald Oussoren84151202010-04-18 20:46:11 +0000786- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
787 (as long as the user didn't specify 'automatic proxy configuration').
788
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000789- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
790 code as stated in RFC-959 at chapter 5.4.
791

800
Victor Stinner0e59cc32010-04-16 23:49:32 +0000801- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
802 the current working directory.
803

814
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000815- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
816 module now takes an optional timeout argument in seconds. Timeout support
817 relies on the system threading library, so as to avoid a semi-busy wait
818 loop.
819

822 Python 2.x and 3.0
823
R. David Murrayb2416e52010-04-12 16:58:02 +0000824- Issue #7585: difflib context and unified diffs now place a tab between
825 filename and date, conforming to the 'standards' they were originally
826 designed to follow. This improves compatibility with patch tools.
827
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000828- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
829 character sets will now consistently use a Content-Transfer-Encoding of
830 7bit rather than sometimes being marked as 8bit.
831
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000832- Issue #8375: test_distutils now checks if the temporary directory are still
833 present before it cleans them.
834
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000835- Issue #8374: Update the internal alias table in the :mod:`locale` module
836 to cover recent locale changes and additions.
837
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000838- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
839 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
840 and `ssl.OPENSSL_VERSION_NUMBER`.
841
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000842- Add functools.total_ordering() and functools.cmp_to_key().
843
Mark Dickinson089b00c2010-04-03 15:51:03 +0000844- Issue #8257: The Decimal construct now accepts a float instance
845 directly, converting that float to a Decimal of equal value:
846
847 >>> Decimal(1.1)
848 Decimal('1.100000000000000088817841970012523233890533447265625')
849
Mark Dickinson98127c32010-04-03 11:18:52 +0000850- Issue #8294: The Fraction constructor now accepts Decimal and float
851 instances directly.
852
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000853- Issue #7279: Comparisons involving a Decimal signaling NaN now
854 signal InvalidOperation instead of returning False. (Comparisons
855 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
856 are now hashable; Decimal signaling NaNs remain unhashable.
857
858- Issue #2531: Comparison operations between floats and Decimal
859 instances now return a result based on the numeric values of the
860 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000861 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000862 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000863
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000864- Added a subtract() method to collections.Counter().
865
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000866- Issue #8233: When run as a script, py_compile.py optionally takes a single
867 argument `-` which tells it to read files to compile from stdin. Each line
868 is read on demand and the named file is compiled immediately. (Original
869 patch by Piotr Ożarowski).
870
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000871- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
872 form feed (0x0C) are now considered linebreaks, as specified in Unicode
873 Standard Annex #14. See issue #7643.
874 http://www.unicode.org/reports/tr14/
875
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000876- Comparisons using one of <, <=, >, >= between a complex instance and
877 a Fractions instance now raise TypeError instead of returning
878 True/False. This makes Fraction <=> complex comparisons consistent with
879 int <=> complex, float <=> complex, and complex <=> complex comparisons.

1191 as zipfiles, directories and other valid sys.path entries that contain a
1192 __main__.py file. This allows applications that run other Python scripts to
1193 support the same flexibility as the CPython command line itself.

Antoine Pitrou45d61a32009-11-13 22:35:18 +00001195- Issue #7318: multiprocessing now uses a timeout when it fails to establish
1196 a connection with another process, rather than looping endlessly. The
1197 default timeout is 20 seconds, which should be amply sufficient for
1198 local connections.
1199
Antoine Pitrouc63ecee2009-11-10 21:34:48 +00001200- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and

Antoine Pitrou434736a2009-11-10 18:46:01 +00001211- Issue #3001: Add a C implementation of recursive locks which is used by
Victor Stinnere125f132010-05-15 21:04:43 +00001212 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001213 recursive locks as fast as regular non-recursive locks (previously,
1214 they were slower by 10x to 15x).
1215

1231 failures on systems with slightly bogus mtime behaviour.
1232
Gregory P. Smith50467882009-11-01 18:42:17 +00001233- Issue #7246 & Issue #7208: getpass now properly flushes input before
1234 reading from stdin so that existing input does not confuse it and
1235 lead to incorrect entry or an IOError. It also properly flushes it
1236 afterwards to avoid the terminal echoing the input afterwards on
1237 OSes such as Solaris.
1238
Mark Dickinsona2d1fe02009-10-29 12:23:02 +00001239- Issue #7233: Fix a number of two-argument Decimal methods to make

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001437- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1438 10,000. Prior to this change, timezone adjustment in utctimetuple()
1439 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1440 raised in these edge cases.
1441
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001442- Issue #6641: The ``datetime.strptime`` method now supports the
1443 ``%z`` directive. When the ``%z`` directive is present in the
1444 format string, an aware ``datetime`` object is returned with
1445 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1446 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1447 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1448 without ``%z`` is discarded.
1449
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001450- Issue #5094: The ``datetime`` module now has a simple concrete class
1451 implementing ``datetime.tzinfo`` interface. Instances of the new
1452 class, ``datetime.timezone``, return fixed name and UTC offset from
1453 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1454 method always returns ``None``. A class attribute, ``utc`` contains
1455 an instance representing the UTC timezone. Original patch by Rafe
1456 Kaplan.

1473 algorithm with an improved 'binary-split' algorithm that uses fewer
1474 multiplications and allows many of the multiplications to be
1475 performed using plain C integer arithmetic instead of PyLong

1747 between concurrent executions on the same system.
1748
Brett Cannon0ae45112009-11-05 01:17:22 +00001749- Issue #7248: In importlib.test.source.util a try/finally block did not make

1754 leak-chasing test runs give sensible results. The previous method of
1755 reaping threads could return successfully while some Thread objects were
1756 still referenced. This also introduces a new private function:
1757 :func:`_thread._count()`.
1758
R. David Murray27144602009-10-19 15:26:16 +00001759- Issue #7151: fixed regrtest -j so that output to stderr from a test no

1761
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001762- Issue #7055: test___all__ now greedily detects all modules which have an

Benjamin Petersonbd35b032009-04-04 23:16:41 +00002044
2045Core and Builtins
2046-----------------
2047
Mark Dickinson865e01a2009-05-07 16:37:01 +00002048- Issue #5914: Add new C API function PyOS_string_to_double, and
2049 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2050
Eric Smith741191f2009-05-06 13:08:15 +00002051- Issue #3382: float.__format__, complex.__format__, and %-formatting
2052 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2053 affects nan -> NAN and inf -> INF.
2054
Mark Hammond5a607a32009-05-06 08:04:54 +00002055- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2056 in all operations, including splitdrive, split, etc. splitunc() now issues
2057 a PendingDeprecation warning.
2058
Eric Smith63376222009-05-05 14:04:18 +00002059- Issue #5920: For float.__format__, change the behavior with the
2060 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2061 to be like 'g' but with at least one decimal point and with a
2062 default precision of 12. Previously, the behavior the same but with
2063 a default precision of 6. This more closely matches str(), and
2064 reduces surprises when adding alignment flags to the empty
2065 presentation type. This also affects the new complex.__format__ in
2066 the same way.
2067
Martin v. Löwis011e8422009-05-05 04:43:17 +00002068- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2069
R. David Murrayb18500d2009-05-04 22:59:07 +00002070- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2071 shadowed by classtype's, even if it was None. property now
2072 inserts the __doc__ into the subclass instance __dict__.
2073
Antoine Pitrou244651a2009-05-04 18:56:13 +00002074- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2075 sequences. Patch by Nick Barnes and Victor Stinner.
2076
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002077- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002078
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002079- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2080 received a new method, detach(). detach() disconnects the underlying stream
2081 from the buffer or text IO and returns it.
2082
Mark Dickinson33841c32009-05-01 15:37:04 +00002083- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2084 floats with absolute value over 1e50. Also remove length
2085 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2086 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002087
Eric Smith741191f2009-05-06 13:08:15 +00002088- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002089 format(complex(1, 2./3), '.5') now produces a sensible result.
2090
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002091- Issue #5864: Fix empty format code formatting for floats so that it
2092 never gives more than the requested number of significant digits.
2093
Eric Smith6dc46f52009-04-27 20:39:49 +00002094- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2095 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2096
Eric Smithcc32a112009-04-26 21:35:14 +00002097- Issue #5835: Deprecate PyOS_ascii_formatd.
2098
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002099- Issue #4971: Fix titlecase for characters that are their own
2100 titlecase, but not their own uppercase.
2101
Benjamin Peterson193152c2009-04-25 01:08:45 +00002102- Issue #5283: Setting __class__ in __del__ caused a segfault.
2103
Mark Dickinsonad476da2009-04-23 19:14:16 +00002104- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2105 z involves nans, infs or negative zeros.
2106
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002107- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002108
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002109- Issue #1869 (and many duplicates): make round(x, n) correctly
2110 rounded for a float x, by using the decimal <-> binary conversions
2111 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2112 consistently agrees with format(x, '.2f').
2113
Benjamin Petersonae937c02009-04-18 20:54:08 +00002114- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2115 some builtin types.
2116
Eric Smith0923d1d2009-04-16 20:16:10 +00002117- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2118
Eric Smith35e84722009-04-16 20:21:28 +00002119- Issue #5515: str.format() type 'n' combined with commas and leading
2120 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002121
2122- Implement PEP 378, Format Specifier for Thousands Separator, for
2123 floats.
2124
Mark Dickinson3370cce2009-04-17 22:40:53 +00002125- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002126 1e11, not 1e12. This avoids printing 13 significant digits in
2127 situations where only 12 of them are correct. Example problem
2128 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2129 long time.)
2130
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002131- Issue #1580: On most platforms, use a 'short' float repr: for a
2132 finite float x, repr(x) now outputs a string based on the shortest
2133 sequence of decimal digits that rounds to x. Previous behaviour was
2134 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002135 Another minor difference is that the new repr switches to
2136 exponential notation at 1e16 instead of the previous 1e17; this
2137 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002138
2139 There's a new sys attribute sys.float_repr_style, which takes
2140 the value 'short' to indicate that we're using short float repr,
2141 and 'legacy' if the short float repr isn't available for one
2142 reason or another.
2143
2144 The float repr change involves incorporating David Gay's 'perfect
2145 rounding' code into the Python core (it's in Python/dtoa.c). As a
2146 secondary consequence, all string-to-float and float-to-string
2147 conversions (including all float formatting operations) will be
2148 correctly rounded on these platforms.
2149
2150 See issue 1580 discussions for details of platforms for which
2151 this change does not apply.
2152
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002153- Issue #5759: float() didn't call __float__ on str subclasses.
2154
Georg Brandlabc38772009-04-12 15:51:51 +00002155- The string.maketrans() function is deprecated; there is a new static method
2156 maketrans() on the bytes and bytearray classes. This removes confusion about
2157 the types string.maketrans() is supposed to work with, and mirrors the
2158 methods available on the str class.
2159
R. David Murraydc6da8a2009-04-09 22:16:43 +00002160- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2161 its clarity and its speed.
2162
Matthias Klose091c7b12009-04-07 13:24:27 +00002163- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2164 to avoid compiler warnings.
2165
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002166- Issue #3739: The unicode-internal encoder now reports the number of characters
2167 consumed like any other encoder (instead of the number of bytes).
2168

2249 and POLLNVAL now call handle_close, not handle_expt_event. Also,
2250 dispatcher now has an 'ignore_log_types' attribute for suppressing

2325
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002326- Issue #4688: Add a heuristic so that tuples and dicts containing only
2327 untrackable objects are not tracked by the garbage collector. This can
2328 reduce the size of collections and therefore the garbage collection overhead
2329 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002452- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2453 it now forces its argument to double before testing for infinity.
2454
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002455- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002464
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002465- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002466 were suppressing all exceptions. These include list() and bytearray().
2467
Mark Dickinson1124e712009-01-28 21:25:58 +00002468- Issue #4707: round(x, n) now returns an integer if x is an integer.
2469 Previously it returned a float.
2470
Antoine Pitroub52ec782009-01-25 16:34:23 +00002471- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2472 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2473 evaluation loop is compiled with a new dispatch mechanism which gives
2474 speedups of up to 20%, depending on the system, on various benchmarks.
2475

2484 optional module state data.
2485
Mark Dickinson8055afd2009-01-17 10:04:45 +00002486- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2487 type to (void *).
2488
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002489- Issue #4935: The overflow checking code in the expandtabs() method common
2490 to str, bytes and bytearray could be optimized away by the compiler, letting
2491 the interpreter segfault instead of raising an error.
2492
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002493- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2494 __next__ method.
2495
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002496- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2497 function no longer attempt to call the __long__ slot to convert an object
2498 to an integer. Only the __int__ and __trunc__ slots are examined.
2499
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002500- Issue #4893: Use NT threading on CE.
2501

2503
Antoine Pitrouab868312009-01-10 15:40:25 +00002504- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2505 common cases are optimized thanks to a dedicated fast path and a moderate
2506 amount of loop unrolling.
2507
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002508- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2509 collecting the oldest generation) so that allocating lots of objects without
2510 destroying them does not show quadratic performance. Based on a proposal by
2511 Martin von Löwis at
2512 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2513
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002514- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002515 having been closed (for instance, a read() call could return some
2516 previously buffered data). Patch by Dmitry Vasiliev.
2517
Antoine Pitrou05608432009-01-09 18:53:14 +00002518- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2519 flag to work properly. Furthermore, when specifying -u, the text stdout
2520 and stderr streams have line-by-line buffering enabled (the default being
2521 to buffer arbitrary chunks of data).
2522
Raymond Hettinger35631532009-01-09 03:58:09 +00002523- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2524 instead of ints (reducing its size from 4 to 8 times thereby reducing
2525 Python's overall memory).
2526
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002527- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2528 an existing .py counterpart, override the co_filename attributes of all
2529 code objects if the original filename is obsolete (which can happen if the
2530 file has been renamed, moved, or if it is accessed through different paths).
2531 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2532
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002533- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2534 one byte. Also fixes the meaning of len() so that it returns the number of
2535 items, rather than the size in bytes.
2536
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002537- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2538
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002539- Issue #4747: When the terminal does not use utf-8, executing a script with
2540 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2541
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002542- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002543 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002544
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002545- Issue #3680: Reference cycles created through a dict, set or deque iterator
2546 did not get collected.
2547
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002548- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2549 where the tp_hash and tp_dict slots are both NULL.
2550
Georg Brandlccc47b62008-12-28 11:44:14 +00002551- Issue #4759: None is now allowed as the first argument of
2552 bytearray.translate(). It was always allowed for bytes.translate().
2553
Skip Montanaro80072cb2008-12-23 03:51:14 +00002554- Added test case to ensure attempts to read from a file opened for writing
2555 fail.

2564 unreachable. Original patch by Neil Schemenauer.
2565
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002566- Issue #3439: Add a bit_length method to int.
2567
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002568- Issue #2173: When getting device encoding, check that return value of
2569 nl_langinfo is not the empty string. This was causing silent build
2570 failures on OS X.
2571
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002572- Issue #4597: Fixed several opcodes that weren't always propagating
2573 exceptions.
2574
2575- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002576 context manager returns a value that cannot be converted to a bool.
2577
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002578- Issue #4445: Replace "sizeof(PyBytesObject)" with
2579 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2580 bytes instances. On a typical machine this saves 3 bytes of memory
2581 (on average) per allocation of a bytes instance.
2582
Christian Heimesa872de52008-12-05 08:26:55 +00002583- Issue #4533: File read operation was dreadfully slow due to a slowly
2584 growing read buffer. Fixed by using the same growth rate algorithm as
2585 Python 2.x.
2586
Antoine Pitrou5504e892008-12-06 21:27:53 +00002587- Issue #4509: Various issues surrounding resize of bytearray objects to
2588 which there are buffer exports (e.g. memoryview instances).
2589
Georg Brandlf9734072008-12-07 15:30:06 +00002590- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2591 method on file objects with closefd=False. The file descriptor is still
2592 kept open but the file object behaves like a closed file. The ``FileIO``
2593 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002595- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2603 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2604 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2605 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00003207- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3208 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00003210- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3211 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
3212 the same behaviour as test_ttkguionly (and now also test_tk) which is to
3213 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00003215- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003216 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003217 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00003219- Issue #5083: New 'gui' resource for regrtest.
