11
12Core and Builtins
13-----------------
14
Victor Stinner8182b712010-07-28 00:40:58 +000015- Issue #8991: convertbuffer() rejects discontigious buffers.
16
Antoine Pitrou1ac745b2010-07-11 12:12:00 +000017- Issue #7616: Fix copying of overlapping memoryview slices with the Intel
18 compiler.
19
Benjamin Petersonccabcd42010-07-07 20:54:01 +000020- Issue #8413: structsequence now subclasses tuple.
21
Ezio Melotti57221d02010-07-01 07:32:02 +000022- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
23 start byte and the continuation byte(s) are now considered invalid, instead
24 of the number of bytes specified by the start byte.
25 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
26 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
27 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
28 Previous versions returned a single u'\ufffd'.
29
Mark Dickinson50b79a82010-06-30 11:13:36 +000030- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real
31 part -0.0 rather than 0.0. So "-7j" is now exactly equivalent to
32 "-(7j)".
33
Benjamin Peterson88968ad2010-06-25 19:30:21 +000034- Be more specific in error messages about positional arguments.
35
Victor Stinner4aae1eb2010-06-24 22:08:25 +000036- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
37 objects, as described in the documentation.
38
Victor Stinner0fe25a42010-06-17 23:08:50 +000039- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000040 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
41 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000042
Mark Dickinsond35a32e2010-06-17 12:33:22 +000043- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
44 compilation code dealing with unary minus applied to a constant.
45 The removed code was mutating the ST, causing a second compilation
46 to fail.
47
Victor Stinner554f3f02010-06-16 23:33:54 +000048- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
49 mode raises unicode errors. The encoder only supports "strict" and "replace"
50 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000051 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000052
Victor Stinner25e8ec42010-06-25 00:02:38 +000053- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
54 "w*" format instead. Add tests for "w*" format.
55
Victor Stinner06e49dd2010-06-13 18:21:50 +000056- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
57 formats if the string contains a null byte/character. Write unit tests for
58 string formats.
59
Nick Coghlan5e76e942010-06-12 13:42:46 +000060- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
61 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
62 location of the raised exception.
63
Victor Stinner313a1202010-06-11 23:56:51 +000064- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
65 filenames and enable os.fsencode().
66
Benjamin Peterson285a6892010-06-22 19:21:52 +000067- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
68
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000069- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
70 the interpreter with characters outside the Basic Multilingual Plane
71 (higher than 0x10000).
72
Mark Dickinsonc7301312010-06-10 16:05:10 +000073- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
74 raise TypeError instead of giving a DeprecationWarning when a float
75 is parsed using the 'L' code (for long long). (All other integer
76 codes already raise TypeError in this case.)
77
Victor Stinner600d3be2010-06-10 12:00:55 +000078- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
79 enable shortcuts for upper case encoding name. Add also a shortcut for
80 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
81
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000082- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
83 doesn't support "char buffer" anymore in Python3.
84
85- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
86 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
87 like bytearray.
88
Victor Stinner33109a12010-05-28 21:55:10 +000089- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
90 used anymore and it was never documented.
91
Benjamin Peterson95304522010-06-08 14:57:22 +000092- In the str.format(), raise a ValueError when indexes to arguments are too
93 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000094
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000095- Issue #2844: Make int('42', n) consistently raise ValueError for
96 invalid integers n (including n = -909).
97
Mark Dickinsondc787d22010-05-23 13:33:13 +000098- Issue #8188: Introduce a new scheme for computing hashes of numbers
99 (instances of int, float, complex, decimal.Decimal and
100 fractions.Fraction) that makes it easy to maintain the invariant
101 that hash(x) == hash(y) whenever x and y have equal value.
102
Mark Dickinsoncc6a9822010-05-21 14:55:26 +0000103- Issue #8748: Fix two issues with comparisons between complex and integer
104 objects. (1) The comparison could incorrectly return True in some cases
105 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
106 (2) The comparison raised an OverflowError for large integers, leading
107 to unpredictable exceptions when combining integers and complex objects
108 in sets or dicts.
109
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000110- Issue #8766: Initialize _warnings module before importing the first module.
111 Fix a crash if an empty directory called "encodings" exists in sys.path.
112
Victor Stinner9ca9c252010-05-19 16:53:30 +0000113- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
114 encoding and surrogateespace error handler instead of the locale encoding to
115 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
116
Victor Stinner372ac5e2010-05-17 01:26:01 +0000117- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
118 (instead of strict) error handler to escape surrogates
119
Victor Stinnerae6265f2010-05-15 16:27:27 +0000120- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
121 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000122 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
123 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000124
Victor Stinner59e62db2010-05-15 13:14:32 +0000125- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
126 error handler, not only the default error handler (strict)
127
Victor Stinnerb744ba12010-05-15 12:27:16 +0000128- Issue #8610: Load file system codec at startup, and display a fatal error on
129 failure. Set the file system encoding to utf-8 (instead of None) if getting
130 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
131
Victor Stinner0964ee12010-04-30 16:48:45 +0000132- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
133 PyUnicode_FromString() to support surrogates in the filename and use the
134 right encoding
135
Georg Brandl8569e582010-05-19 20:57:08 +0000136- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
137
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000138- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
139
Benjamin Petersonfb886362010-04-24 18:21:17 +0000140- Issue #8419: Prevent the dict constructor from accepting non-string keyword
141 arguments.
142
Victor Stinner14284c22010-04-23 12:02:30 +0000143- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
144 indirectly Python signal handlers anymore because mywrite() ignores
145 exceptions (KeyboardInterrupt)
146
Victor Stinner31be90b2010-04-22 19:38:16 +0000147- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
148 unicode string (eg. backslashreplace)
149
Victor Stinnerdcb24032010-04-22 12:08:36 +0000150- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
151 you have to convert your bytearray filenames to bytes
152
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000153- Issue #7332: Remove the 16KB stack-based buffer in
154 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
155 benefit compared to the dynamic memory allocation fallback. Patch by
156 Charles-François Natali.
157
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000158- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
159 passed to bytes or bytearray.
160
Philip Jenvey0805ca32010-04-07 04:04:10 +0000161- Issue #7301: Add environment variable $PYTHONWARNINGS.
162
Benjamin Petersond856ab62010-04-06 21:55:16 +0000163- Issue #8329: Don't return the same lists from select.select when no fds are
164 changed.
165
Mark Dickinson3318d292010-04-06 16:53:17 +0000166- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
167 on 64-bit machines. The shift count for either left or right shift is
168 permitted to be up to sys.maxsize.
169
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000170- Ensure that tokenization of identifiers is not affected by locale.

177 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000178
Victor Stinner120c2122010-03-25 00:30:28 +0000179- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
180 is unknown
181

183
Mark Dickinsond59b4162010-03-13 11:34:40 +0000184- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
185 PyMemberDefs could produce an internal error; raise TypeError instead.
186
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000187- Issue #7845: Rich comparison methods on the complex type now return
188 NotImplemented rather than raising a TypeError when comparing with an
189 incompatible type; this allows user-defined classes to implement their own
190 comparisons with complex.
191
Victor Stinner52f6dd72010-03-12 14:45:56 +0000192- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
193 (SIGINT). If an error occurs while importing the site module, the error is
194 printed and Python exits. Initialize the GIL before importing the site
195 module.
196
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000197- Issue #7173: Generator finalization could invalidate sys.exc_info().

200 a fatal error in low memory condition.
201
Victor Stinner6aa278e2010-03-03 00:18:49 +0000202- Issue #7820: The parser tokenizer restores all bytes in the right if
203 the BOM check fails.
204
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000205- Handle errors from looking up __prepare__ correctly.
206
Larry Hastings1373a072010-02-24 22:49:58 +0000207- Issue #5939: Add additional runtime checking to ensure a valid capsule
208 in Modules/_ctypes/callproc.c.
209
Eric Smith0facd772010-02-24 15:42:29 +0000210- Issue #7309: Fix unchecked attribute access when converting

223 deprecations.
224
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000225- Issue #7385: Fix a crash in `MemoryView_FromObject` when
226 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
227
Mark Dickinsonbc099642010-01-29 17:27:24 +0000228- Issue #7788: Fix an interpreter crash produced by deleting a list
229 slice with very large step value.
230
Eric Smithf7bb5782010-01-27 00:44:57 +0000231- Issue #7766: Change sys.getwindowsversion() return value to a named
232 tuple and add the additional members returned in an OSVERSIONINFOEX
233 structure. The new members are service_pack_major, service_pack_minor,
234 suite_mask, and product_type.
235
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000236- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
237 could crash in many places because of the PyByteArray_AS_STRING() macro
238 returning NULL. The macro now returns a statically allocated empty
239 string instead.
240
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000241- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
242 where the right hand operand is a set of constants, by turning the set into
243 a frozenset and pre-building it as a constant. The comparison operation
244 is made against the constant instead of building a new set each time it is
245 executed (a similar optimization already existed which turned a list of
246 constants into a pre-built tuple). Patch and additional tests by Dave
247 Malcolm.
248
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000249- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
250 methods of bytes, bytearray and unicode objects by using a common
251 implementation based on stringlib's fast search. Patch by Florent Xicluna.
252
Mark Dickinson45b63652010-01-16 18:10:25 +0000253- Issue #7632: Fix various str -> float conversion bugs present in 2.7
254 alpha 2, including: (1) a serious 'wrong output' bug that could
255 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
256 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000257 strings corresponding to subnormal values, (3) a memory leak for
258 some values large enough to cause overflow, and (4) a number of
259 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000260
Benjamin Petersonaea44282010-01-04 01:10:28 +0000261- The __complex__ method is now looked up on the class of instances to make it
262 consistent with other special methods.

271 negative zero) in ** operator. The behaviour now conforms to that
272 described in C99 Annex F.
273
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000274- Issue #1811: improve accuracy and cross-platform consistency for
275 true division of integers: the result of a/b is now correctly
276 rounded for ints a and b (at least on IEEE 754 platforms), and in
277 particular does not depend on the internal representation of an int.
278
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000279- Issue #6834: replace the implementation for the 'python' and 'pythonw'
280 executables on OSX.
281
282 These executables now work properly with the arch(1) command:
283 ``arch -ppc python`` will start a universal binary version of python
284 in PPC mode (unlike previous releases).
285
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000286- Issue #7466: segmentation fault when the garbage collector is called
287 in the middle of populating a tuple. Patch by Florent Xicluna.
288
Amaury Forgeot d'Arc64f3ca42009-12-01 21:59:18 +0000289- Issue #7419: setlocale() could crash the interpreter on Windows when called
290 with invalid values.
291
Amaury Forgeot d'Arc7d0bddd2009-11-30 00:08:56 +0000292- Issue #6077: On Windows, files opened with tempfile.TemporaryFile in "wt+"
293 mode would appear truncated on the first '0x1a' byte (aka. Ctrl+Z).
294
Ronald Oussoren3c1928a2009-11-19 17:15:31 +0000295- Issue #7085: Fix crash when importing some extensions in a thread

302
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000303- Issue #7298: fixes for range and reversed(range(...)). Iteration
304 over range(a, b, c) incorrectly gave an empty iterator when a, b and
305 c fit in C long but the length of the range did not. Also fix
306 several cases where reversed(range(a, b, c)) gave wrong results, and
307 fix a refleak for reversed(range(a, b, c)) with large arguments.
308
Raymond Hettingerfc438512009-11-01 20:55:33 +0000309- Issue #7244: itertools.izip_longest() no longer ignores exceptions
310 raised during the formation of an output tuple.

418
Antoine Pitrouf978fac2010-05-21 17:25:34 +0000419- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
420 embedders of the interpreter to set sys.argv without also modifying
421 sys.path. This helps fix `CVE-2008-5983

438 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
439 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
440 DeprecationWarning for float arguments passed with the 'L' format
441 code. This will become a TypeError in a future version of Python,
442 to match the behaviour of the other integer format codes.
443

Gregory P. Smith5a631832010-07-27 05:31:29 +0000494- The default size of the re module's compiled regular expression cache has
495 been increased from 100 to 500 and the cache replacement policy has changed
496 from simply clearing the entire cache on overflow to randomly forgetting 20%
497 of the existing cached compiled regular expressions. This is a performance
498 win for applications that use a lot of regular expressions and limits the
499 impact of the performance hit anytime the cache is exceeded.

513 overrides all classes defined in datetime with fast C impementation.
514 Python implementation is based on the original python prototype for
515 the datetime module by Tim Peters with minor modifications by the

Mark Dickinson08ade6f2010-06-11 10:44:52 +0000621 now permitted, returning a result based on the exact numerical
622 values of the operands. This builds on issue #2531, which allowed
623 Decimal-to-float comparisons; all comparisons involving numeric
624 types (bool, int, float, complex, Decimal, Fraction) should now
625 act as expected.

757
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000758- Issue #8567: Fix precedence of signals in Decimal module: when a
759 Decimal operation raises multiple signals and more than one of those
760 signals is trapped, the specification determines the order in which
761 the signals should be handled. In many cases this order wasn't
762 being followed, leading to the wrong Python exception being raised.

795
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000796- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
797 where the method could block indefinitely if called just before the
798 event loop started running. This also fixes the occasional freezes
799 witnessed in test_httpservers.
800
Antoine Pitrou40f08742010-04-24 22:04:40 +0000801- Issue #8524: When creating an SSL socket, the timeout value of the
802 original socket wasn't retained (instead, a socket with a positive timeout
803 would be turned into a non-blocking SSL socket).
804
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000805- Issue #5103: SSL handshake would ignore the socket timeout and block
806 indefinitely if the other end didn't respond.
807
808- The do_handshake() method of SSL objects now adjusts the blocking mode of
809 the SSL structure if necessary (as other methods already do).
810
Victor Stinner13bb71c2010-04-23 21:41:56 +0000811- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

Raymond Hettingerc50846a2010-04-05 18:56:31 +0000905- Add functools.total_ordering() and functools.cmp_to_key().
906
Mark Dickinson089b00c2010-04-03 15:51:03 +0000907- Issue #8257: The Decimal construct now accepts a float instance
908 directly, converting that float to a Decimal of equal value:
909
910 >>> Decimal(1.1)
911 Decimal('1.100000000000000088817841970012523233890533447265625')
912
Mark Dickinson98127c32010-04-03 11:18:52 +0000913- Issue #8294: The Fraction constructor now accepts Decimal and float
914 instances directly.
915
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000916- Issue #7279: Comparisons involving a Decimal signaling NaN now
917 signal InvalidOperation instead of returning False. (Comparisons
918 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
919 are now hashable; Decimal signaling NaNs remain unhashable.
920
921- Issue #2531: Comparison operations between floats and Decimal
922 instances now return a result based on the numeric values of the
923 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000924 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000925 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000926
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000927- Added a subtract() method to collections.Counter().
928
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000929- Issue #8233: When run as a script, py_compile.py optionally takes a single
930 argument `-` which tells it to read files to compile from stdin. Each line
931 is read on demand and the named file is compiled immediately. (Original
932 patch by Piotr Ożarowski).
933
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000934- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
935 form feed (0x0C) are now considered linebreaks, as specified in Unicode
936 Standard Annex #14. See issue #7643.
937 http://www.unicode.org/reports/tr14/
938
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000939- Comparisons using one of <, <=, >, >= between a complex instance and
940 a Fractions instance now raise TypeError instead of returning
941 True/False. This makes Fraction <=> complex comparisons consistent with
942 int <=> complex, float <=> complex, and complex <=> complex comparisons.
943
Antoine Pitrou39b35432010-03-23 00:25:54 +0000944- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
945 some methods (such as oss_mixer_device.fileno()) were not available.
946 Initial patch by Bertrand Janin.
947
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000948- Issue #8205: Remove the "Modules" directory from sys.path when Python is
949 running from the build directory (POSIX only).
950
Antoine Pitrou910bd512010-03-22 20:11:09 +0000951- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
952 didn't support chflags() (for example ZFS under FreeBSD). The error is
953 now silenced.
954
R. David Murrayca2edce2010-03-22 17:48:48 +0000955- Issue #7860: platform.uname now reports the correct 'machine' type
956 when Python is running in WOW64 mode on 64 bit Windows.
957
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000958- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
959 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
960 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000961
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000962- Issue #4282: Fix the main function of the profile module for a non-ASCII
963 script, open the file in binary mode and not in text mode with the default
964 (utf8) encoding.
965
Florent Xicluna54467e02010-03-21 12:29:50 +0000966- Issue #8179: Fix macpath.realpath() on a non-existing path.

969
Benjamin Peterson00888932010-03-18 22:37:38 +0000970- Issue #8168: py_compile now handles files with utf-8 BOMS.
971
Benjamin Peterson689a5582010-03-18 22:29:52 +0000972- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
973 detected.
974
Martin v. Löwis4b003072010-03-16 13:19:21 +0000975- Issue #6716/2: Backslash-replace error output in compilall.
976

978 with Tcl/Tk-8.5.
979

983 the locale.
984
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000985- The internals of the subprocess module on POSIX systems have been replaced
986 by an extension module (_posixsubprocess) so that the fork()+exec() can be
987 done safely without the possibility of deadlock in multithreaded applications.
988
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000989- subprocess.Popen now has restore_signals and start_new_session features.
990 The default of restore_signals=True is a new behavior compared to earlier
991 Python versions. This means that signals such as SIGPIPE are not ignored
992 by default in subprocesses launched by Python (Issue #1652).
993
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000994- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
995 cElementTree module is updated too.

1004 the replacement were all bytes. Patch by Antoine Pitrou.
1005
Gerhard Häringf9cee222010-03-05 15:20:03 +00001006- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
1007 bugs and allows loading SQLite extensions from shared libraries.
1008
Ezio Melottida227042010-03-14 11:51:00 +00001009- Issue #1054943: Fix ``unicodedata.normalize('NFC', text)`` for the Public

Victor Stinnercee3ae82010-03-04 00:29:24 +00001012- Issue #7494: fix a crash in _lsprof (cProfile) after clearing the profiler,
1013 reset also the pointer to the current pointer context.

1022
Florent Xiclunac279ebf2010-02-27 11:31:21 +00001023- Issue #691291: codecs.open() should not convert end of lines on reading and
1024 writing.
1025

1051 bytecode file when it was less then 8 bytes.
1052
Mark Dickinson84230a12010-02-18 14:49:50 +00001053- Issue #7633: In the decimal module, Context class methods (with the
1054 exception of canonical and is_canonical) now accept instances of int
1055 and long wherever a Decimal instance is accepted, and implicitly
1056 convert that argument to Decimal. Previously only some arguments
1057 were converted.
1058
R. David Murray1f449142010-02-11 00:15:05 +00001059- Issue #7835: shelve should no longer produce mysterious warnings during

1061
Antoine Pitrou99f69ee2010-02-09 17:25:47 +00001062- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
1063 in XML processing instructions and comments. These raw characters are
1064 allowed by the XML specification, and are necessary when outputting e.g.
1065 PHP code in a processing instruction. Patch by Neil Muller.
1066
Antoine Pitrouc77dd322010-02-09 16:51:16 +00001067- Issue #6233: ElementTree failed converting unicode characters to XML

1075 specified, rather than fall through to AF_PACKET (in the `socket` module).
1076 Also, raise ValueError rather than TypeError when an unknown TIPC address
1077 type is specified. Patch by Brian Curtin.
1078
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00001079- Issue #6939: Fix file I/O objects in the `io` module to keep the original
1080 file position when calling `truncate()`. It would previously change the
1081 file position to the given argument, which goes against the tradition of
1082 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1083
Antoine Pitroua32f9a22010-01-27 21:18:57 +00001084- Issue #7610: Reworked implementation of the internal
1085 :class:`zipfile.ZipExtFile` class used to represent files stored inside
1086 an archive. The new implementation is significantly faster and can
1087 be wrapped in a :class:`io.BufferedReader` object for more speedups.
1088 It also solves an issue where interleaved calls to `read()` and
1089 `readline()` give wrong results. Patch by Nir Aides.
1090
Jesse Noller1f0b6582010-01-27 03:36:01 +00001091- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
1092 allowing for a maximum number of tasks within the pool to be completed by
1093 the worker before that worker is terminated, and a new one created to
1094 replace it.
1095
Benjamin Petersond6326642010-01-27 02:25:58 +00001096- Issue #7792: Registering non-classes to ABCs raised an obscure error.
1097
Benjamin Peterson9a11a362010-01-27 01:51:29 +00001098- Issue #7785: Don't accept bytes in FileIO.write().

Tarek Ziadéacafc2d2009-11-29 22:24:57 +00001204- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
1205 ownership when the group is not forced, because the group may be different
1206 from the user's group and inherit from its container when the test is run.
1207

1251
Nick Coghlan260bd3e2009-11-16 06:49:25 +00001252- Issue #6816: runpy now provides a run_path function that allows Python code
1253 to execute file paths that refer to source or compiled Python files as well
1254 as zipfiles, directories and other valid sys.path entries that contain a
1255 __main__.py file. This allows applications that run other Python scripts to
1256 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001275 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001276 recursive locks as fast as regular non-recursive locks (previously,
1277 they were slower by 10x to 15x).

1295
Gregory P. Smith50467882009-11-01 18:42:17 +00001296- Issue #7246 & Issue #7208: getpass now properly flushes input before
1297 reading from stdin so that existing input does not confuse it and
1298 lead to incorrect entry or an IOError. It also properly flushes it
1299 afterwards to avoid the terminal echoing the input afterwards on
1300 OSes such as Solaris.
1301
Mark Dickinsona2d1fe02009-10-29 12:23:02 +00001302- Issue #7233: Fix a number of two-argument Decimal methods to make

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001486- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
1487 compared to other unix systems. In particular, os.getgroups() does
1488 not reflect any changes made using os.setgroups() but basicly always
1489 returns the same information as the id command.
1490
1491 os.getgroups() can now return more than 16 groups on MacOSX.
1492
Martin v. Löwisc9e1c7d2010-07-23 12:16:41 +00001493- Issue #6095: Make directory argument to os.listdir optional.
1494
Mark Dickinsone26660f2010-07-18 07:48:20 +00001495- Issue #9277: Fix bug in struct.pack for bools in standard mode
1496 (e.g., struct.pack('>?')): if conversion to bool raised an exception
Mark Dickinson1b3c2622010-07-18 08:03:10 +00001497 then that exception wasn't properly propagated on machines where
1498 char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00001499
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00001500- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x
1501 python when they contain instances of old-style classes.
1502
Mark Dickinson8e0c9962010-07-11 17:38:24 +00001503- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to
1504 accompany existing isinf and isnan functions.
1505
Brian Curtind40e6f72010-07-08 21:39:08 +00001506- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by
1507 Jason R. Coombs
1508
Benjamin Petersona9800a82010-07-07 19:04:48 +00001509- In struct.pack, correctly propogate exceptions from computing the truth of an
1510 object in the '?' format.
1511
Alexander Belopolskya11d8c02010-07-06 23:19:45 +00001512- Issue #9000: datetime.timezone objects now have eval-friendly repr.
1513
Benjamin Petersonf751bc92010-07-02 13:46:42 +00001514- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
1515 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00001516
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001517- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1518 10,000. Prior to this change, timezone adjustment in utctimetuple()
1519 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1520 raised in these edge cases.
1521
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001522- Issue #6641: The ``datetime.strptime`` method now supports the
1523 ``%z`` directive. When the ``%z`` directive is present in the
1524 format string, an aware ``datetime`` object is returned with
1525 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1526 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1527 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1528 without ``%z`` is discarded.
1529
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001530- Issue #5094: The ``datetime`` module now has a simple concrete class
1531 implementing ``datetime.tzinfo`` interface. Instances of the new
1532 class, ``datetime.timezone``, return fixed name and UTC offset from
1533 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1534 method always returns ``None``. A class attribute, ``utc`` contains
1535 an instance representing the UTC timezone. Original patch by Rafe
1536 Kaplan.
1537
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001538- Issue #8973: Add __all__ to struct module; this ensures that
1539 help(struct) includes documentation for the struct.Struct class.
1540
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001541- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001542 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001543 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00001544
Stefan Kraha3ac44e2010-06-08 14:00:52 +00001545- Issue #7384: If the system readline library is linked against ncurses,
1546 the curses module must be linked against ncurses as well. Otherwise it
1547 is not safe to load both the readline and curses modules in an application.
1548
Brian Curtin60853212010-05-26 17:43:50 +00001549- Issue #2810: Fix cases where the Windows registry API returns
1550 ERROR_MORE_DATA, requiring a re-try in order to get the complete result.
1551
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001552- Issue #8692: Optimize math.factorial: replace the previous naive
1553 algorithm with an improved 'binary-split' algorithm that uses fewer
1554 multiplications and allows many of the multiplications to be
1555 performed using plain C integer arithmetic instead of PyLong
1556 arithmetic. Also uses a lookup table for small arguments.
1557
Mark Dickinson85eacea2010-05-10 16:27:45 +00001558- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1559 overflow checks in the audioop module.
1560
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001561- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1562 calculating with integer arithmetic instead of float arithmetic internally):
1563 the result is now always correctly rounded, and is equivalent to td /
1564 timedelta(seconds=1).
1565
Mark Dickinson7c186e22010-04-20 22:32:49 +00001566- Issue #2706: Allow division of a timedelta by another timedelta:
1567 timedelta / timedelta, timedelta % timedelta, timedelta // timedelta
1568 and divmod(timedelta, timedelta) are all supported.
1569
Victor Stinnerfebecd82010-04-16 12:07:30 +00001570- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
1571
Mark Dickinsonc5935772010-04-03 15:54:36 +00001572- Issue #8300: When passing a non-integer argument to struct.pack with any
1573 integer format code, struct.pack first attempts to convert the non-integer
1574 using its __index__ method. If that method is non-existent or raises
1575 TypeError it goes on to try the __int__ method, as described below.
1576
Matthias Klosea8349752010-03-15 13:25:28 +00001577- Issue #8142: Update libffi to the 3.0.9 release.

1602 matched characters with category 'No'.
1603

Antoine Pitrou060cee22009-11-13 16:29:04 +00001823- Issue #6551: test_zipimport could import and then destroy some modules of

Antoine Pitrou65c9c642009-10-30 17:25:12 +00001841- Issue #7222: Make thread "reaping" more reliable so that reference
1842 leak-chasing test runs give sensible results. The previous method of
1843 reaping threads could return successfully while some Thread objects were
1844 still referenced. This also introduces a new private function:
1845 :func:`_thread._count()`.
1846
R. David Murray27144602009-10-19 15:26:16 +00001847- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1848 longer runs the risk of causing the worker thread to fail.
1849
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001850- Issue #7055: test___all__ now greedily detects all modules which have an
1851 __all__ attribute, rather than using a hardcoded and incomplete list.

1855 and a new section in the summary report at the end.

Mark Dickinson2e304402009-10-04 18:43:54 +00001857- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1858
Brett Cannon3c273842009-07-20 00:14:29 +00001859- Fixed tests in importlib.test.source.test_abc_loader that were masking
1860 the proper exceptions that should be raised for missing or improper code
1861 object bytecode.

2038
R. David Murray1f1b9d32009-05-27 20:56:59 +00002039- Issue #6121: pydoc now ignores leading and trailing spaces in the
2040 argument to the 'help' function.
2041
Georg Brandlfaf41492009-05-26 18:31:11 +00002042- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
2043 arguments for strings with a space in them.
2044
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00002045- collections.namedtuple() was not working with the following field

2047
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002048- In unittest, using a skipping decorator on a class is now equivalent to

2050
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002051- Issue #6050: Don't fail extracting a directory from a zipfile if
2052 the directory already exists.
2053
Antoine Pitrou61f77b52009-05-24 15:46:13 +00002054- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
2055 than an int, which makes some operations possible under 64-bit Linux (e.g.
2056 DN_MULTISHOT with F_NOTIFY).
2057
Antoine Pitrou716c4442009-05-23 19:04:03 +00002058- Issue #5761: Add the name of the underlying file to the repr() of various

Antoine Pitrouc3ee1662009-05-23 16:02:33 +00002064- Issue #1983: Fix functions taking or returning a process identifier to use
2065 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
2066 a process identifier type wider than the standard C integer type.
2067
R. David Murray87e20742009-05-23 01:30:26 +00002068- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

2079
Antoine Pitroue4501852009-05-14 18:55:55 +00002080- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2081 library. This means, for example, that opening an UTF-16 text file in
2082 append mode doesn't add a BOM at the end of the file if the file isn't
2083 empty.
2084
R. David Murray74b89242009-05-13 17:33:03 +00002085- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
2086 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
2087 corrects a pydoc regression.
2088
R. David Murray99352742009-05-07 18:24:38 +00002089- Issue 5955: aifc's close method did not close the file it wrapped,
2090 now it does. This also means getfp method now returns the real fp.
2091

Benjamin Petersonbd35b032009-04-04 23:16:41 +00002132
2133Core and Builtins
2134-----------------
2135
Mark Dickinson865e01a2009-05-07 16:37:01 +00002136- Issue #5914: Add new C API function PyOS_string_to_double, and
2137 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2138
Eric Smith741191f2009-05-06 13:08:15 +00002139- Issue #3382: float.__format__, complex.__format__, and %-formatting
2140 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2141 affects nan -> NAN and inf -> INF.
2142
Mark Hammond5a607a32009-05-06 08:04:54 +00002143- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2144 in all operations, including splitdrive, split, etc. splitunc() now issues
2145 a PendingDeprecation warning.
2146
Eric Smith63376222009-05-05 14:04:18 +00002147- Issue #5920: For float.__format__, change the behavior with the
2148 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2149 to be like 'g' but with at least one decimal point and with a
2150 default precision of 12. Previously, the behavior the same but with
2151 a default precision of 6. This more closely matches str(), and
2152 reduces surprises when adding alignment flags to the empty
2153 presentation type. This also affects the new complex.__format__ in
2154 the same way.
2155
Martin v. Löwis011e8422009-05-05 04:43:17 +00002156- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2157
R. David Murrayb18500d2009-05-04 22:59:07 +00002158- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2159 shadowed by classtype's, even if it was None. property now
2160 inserts the __doc__ into the subclass instance __dict__.
2161
Antoine Pitrou244651a2009-05-04 18:56:13 +00002162- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2163 sequences. Patch by Nick Barnes and Victor Stinner.
2164
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002165- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002166
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002167- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2168 received a new method, detach(). detach() disconnects the underlying stream
2169 from the buffer or text IO and returns it.
2170
Mark Dickinson33841c32009-05-01 15:37:04 +00002171- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2172 floats with absolute value over 1e50. Also remove length
2173 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2174 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002175
Eric Smith741191f2009-05-06 13:08:15 +00002176- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002177 format(complex(1, 2./3), '.5') now produces a sensible result.
2178
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002179- Issue #5864: Fix empty format code formatting for floats so that it
2180 never gives more than the requested number of significant digits.
2181
Eric Smith6dc46f52009-04-27 20:39:49 +00002182- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2183 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2184
Eric Smithcc32a112009-04-26 21:35:14 +00002185- Issue #5835: Deprecate PyOS_ascii_formatd.
2186
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002187- Issue #4971: Fix titlecase for characters that are their own
2188 titlecase, but not their own uppercase.
2189
Benjamin Peterson193152c2009-04-25 01:08:45 +00002190- Issue #5283: Setting __class__ in __del__ caused a segfault.
2191
Mark Dickinsonad476da2009-04-23 19:14:16 +00002192- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2193 z involves nans, infs or negative zeros.
2194
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002195- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002196
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002197- Issue #1869 (and many duplicates): make round(x, n) correctly
2198 rounded for a float x, by using the decimal <-> binary conversions
2199 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2200 consistently agrees with format(x, '.2f').
2201
Benjamin Petersonae937c02009-04-18 20:54:08 +00002202- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2203 some builtin types.
2204
Eric Smith0923d1d2009-04-16 20:16:10 +00002205- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2206
Eric Smith35e84722009-04-16 20:21:28 +00002207- Issue #5515: str.format() type 'n' combined with commas and leading
2208 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002209
2210- Implement PEP 378, Format Specifier for Thousands Separator, for
2211 floats.
2212
Mark Dickinson3370cce2009-04-17 22:40:53 +00002213- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002214 1e11, not 1e12. This avoids printing 13 significant digits in
2215 situations where only 12 of them are correct. Example problem
2216 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2217 long time.)
2218
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002219- Issue #1580: On most platforms, use a 'short' float repr: for a
2220 finite float x, repr(x) now outputs a string based on the shortest
2221 sequence of decimal digits that rounds to x. Previous behaviour was
2222 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002223 Another minor difference is that the new repr switches to
2224 exponential notation at 1e16 instead of the previous 1e17; this
2225 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002226
2227 There's a new sys attribute sys.float_repr_style, which takes
2228 the value 'short' to indicate that we're using short float repr,
2229 and 'legacy' if the short float repr isn't available for one
2230 reason or another.
2231
2232 The float repr change involves incorporating David Gay's 'perfect
2233 rounding' code into the Python core (it's in Python/dtoa.c). As a
2234 secondary consequence, all string-to-float and float-to-string
2235 conversions (including all float formatting operations) will be
2236 correctly rounded on these platforms.
2237
2238 See issue 1580 discussions for details of platforms for which
2239 this change does not apply.
2240
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002241- Issue #5759: float() didn't call __float__ on str subclasses.
2242
Georg Brandlabc38772009-04-12 15:51:51 +00002243- The string.maketrans() function is deprecated; there is a new static method
2244 maketrans() on the bytes and bytearray classes. This removes confusion about
2245 the types string.maketrans() is supposed to work with, and mirrors the
2246 methods available on the str class.
2247
R. David Murraydc6da8a2009-04-09 22:16:43 +00002248- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2249 its clarity and its speed.
2250
Matthias Klose091c7b12009-04-07 13:24:27 +00002251- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2252 to avoid compiler warnings.
2253
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002254- Issue #3739: The unicode-internal encoder now reports the number of characters
2255 consumed like any other encoder (instead of the number of bytes).

R. David Murray9e94ddf2009-04-13 17:06:33 +00002335- Issue #1161031: fix readwrite select flag handling: POLLPRI now
2336 results in a handle_expt_event call, not handle_read_event, and POLLERR
2337 and POLLNVAL now call handle_close, not handle_expt_event. Also,
2338 dispatcher now has an 'ignore_log_types' attribute for suppressing
2339 log messages, which is set to 'warning' by default.

2413
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002414- Issue #4688: Add a heuristic so that tuples and dicts containing only
2415 untrackable objects are not tracked by the garbage collector. This can
2416 reduce the size of collections and therefore the garbage collection overhead
2417 on long-running programs, depending on their particular use of datatypes.

2486
Lars Gustäbel42e00912009-03-22 20:34:29 +00002487- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2488 forever on incomplete input. That caused tarfile.open() to hang when used
2489 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2490 partial bzip2 compressed data.
2491
Mark Dickinson79f52032009-03-17 23:12:51 +00002492- Issue #2110: Add support for thousands separator and 'n' type

2607 flag to work properly. Furthermore, when specifying -u, the text stdout
2608 and stderr streams have line-by-line buffering enabled (the default being
2609 to buffer arbitrary chunks of data).
2610
Raymond Hettinger35631532009-01-09 03:58:09 +00002611- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

2618 file has been renamed, moved, or if it is accessed through different paths).
2619 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2620
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002621- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2622 one byte. Also fixes the meaning of len() so that it returns the number of

3012
Antoine Pitrou08838b62009-01-21 00:55:13 +00003013- Issue #5008: When a file is opened in append mode with the new IO library,
3014 do an explicit seek to the end of file (so that e.g. tell() returns the
3015 file size rather than 0). This is consistent with the behaviour of the
