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

Gregory P. Smith5a631832010-07-27 05:31:29 +0000485- The default size of the re module's compiled regular expression cache has
486 been increased from 100 to 500 and the cache replacement policy has changed
487 from simply clearing the entire cache on overflow to randomly forgetting 20%
488 of the existing cached compiled regular expressions. This is a performance
489 win for applications that use a lot of regular expressions and limits the
490 impact of the performance hit anytime the cache is exceeded.

Alexander Belopolskycf86e362010-07-23 19:25:47 +0000502- Issue #7989: Added pure python implementation of the `datetime`
503 module. The C module is renamed to `_datetime` and if available,
504 overrides all classes defined in datetime with fast C impementation.
505 Python implementation is based on the original python prototype for
506 the datetime module by Tim Peters with minor modifications by the
507 PyPy project. The test suite now tests `datetime` module with and
508 without `_datetime` acceleration using the same test cases.

Mark Dickinson9b88b912010-06-11 10:46:57 +0000611- Issue #8188: Comparisons between Decimal and Fraction objects are
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000612 now permitted, returning a result based on the exact numerical
613 values of the operands. This builds on issue #2531, which allowed
614 Decimal-to-float comparisons; all comparisons involving numeric
615 types (bool, int, float, complex, Decimal, Fraction) should now
616 act as expected.

748
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000749- Issue #8567: Fix precedence of signals in Decimal module: when a
750 Decimal operation raises multiple signals and more than one of those
751 signals is trapped, the specification determines the order in which
752 the signals should be handled. In many cases this order wasn't
753 being followed, leading to the wrong Python exception being raised.

786
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000787- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
788 where the method could block indefinitely if called just before the
789 event loop started running. This also fixes the occasional freezes
790 witnessed in test_httpservers.
791
Antoine Pitrou40f08742010-04-24 22:04:40 +0000792- Issue #8524: When creating an SSL socket, the timeout value of the
793 original socket wasn't retained (instead, a socket with a positive timeout
794 would be turned into a non-blocking SSL socket).
795
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000796- Issue #5103: SSL handshake would ignore the socket timeout and block
797 indefinitely if the other end didn't respond.
798
799- The do_handshake() method of SSL objects now adjusts the blocking mode of
800 the SSL structure if necessary (as other methods already do).
801
Victor Stinner13bb71c2010-04-23 21:41:56 +0000802- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

905 instances directly.
906
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000907- Issue #7279: Comparisons involving a Decimal signaling NaN now
908 signal InvalidOperation instead of returning False. (Comparisons
909 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
910 are now hashable; Decimal signaling NaNs remain unhashable.
911
912- Issue #2531: Comparison operations between floats and Decimal
913 instances now return a result based on the numeric values of the
914 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000915 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000916 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000917
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000918- Added a subtract() method to collections.Counter().
919
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000920- Issue #8233: When run as a script, py_compile.py optionally takes a single
921 argument `-` which tells it to read files to compile from stdin. Each line
922 is read on demand and the named file is compiled immediately. (Original
923 patch by Piotr Ożarowski).
924
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000925- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
926 form feed (0x0C) are now considered linebreaks, as specified in Unicode
927 Standard Annex #14. See issue #7643.
928 http://www.unicode.org/reports/tr14/
929
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000930- Comparisons using one of <, <=, >, >= between a complex instance and
931 a Fractions instance now raise TypeError instead of returning
932 True/False. This makes Fraction <=> complex comparisons consistent with
933 int <=> complex, float <=> complex, and complex <=> complex comparisons.
934
Antoine Pitrou39b35432010-03-23 00:25:54 +0000935- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
936 some methods (such as oss_mixer_device.fileno()) were not available.
937 Initial patch by Bertrand Janin.
938
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000939- Issue #8205: Remove the "Modules" directory from sys.path when Python is

941
Antoine Pitrou910bd512010-03-22 20:11:09 +0000942- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
943 didn't support chflags() (for example ZFS under FreeBSD). The error is
944 now silenced.
945
R. David Murrayca2edce2010-03-22 17:48:48 +0000946- Issue #7860: platform.uname now reports the correct 'machine' type
947 when Python is running in WOW64 mode on 64 bit Windows.
948
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000949- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
950 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
951 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000952

Benjamin Peterson00888932010-03-18 22:37:38 +0000961- Issue #8168: py_compile now handles files with utf-8 BOMS.
962
Benjamin Peterson689a5582010-03-18 22:29:52 +0000963- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
964 detected.
965
Martin v. Löwis4b003072010-03-16 13:19:21 +0000966- Issue #6716/2: Backslash-replace error output in compilall.

974 the locale.
975
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000976- The internals of the subprocess module on POSIX systems have been replaced
977 by an extension module (_posixsubprocess) so that the fork()+exec() can be
978 done safely without the possibility of deadlock in multithreaded applications.
979
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000980- subprocess.Popen now has restore_signals and start_new_session features.
981 The default of restore_signals=True is a new behavior compared to earlier
982 Python versions. This means that signals such as SIGPIPE are not ignored
983 by default in subprocesses launched by Python (Issue #1652).
984
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000985- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

995 the replacement were all bytes. Patch by Antoine Pitrou.
996
Gerhard Häringf9cee222010-03-05 15:20:03 +0000997- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
998 bugs and allows loading SQLite extensions from shared libraries.
999

1045 exception of canonical and is_canonical) now accept instances of int
1046 and long wherever a Decimal instance is accepted, and implicitly
1047 convert that argument to Decimal. Previously only some arguments
1048 were converted.

Antoine Pitrou99f69ee2010-02-09 17:25:47 +00001053- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
1054 in XML processing instructions and comments. These raw characters are
1055 allowed by the XML specification, and are necessary when outputting e.g.
1056 PHP code in a processing instruction. Patch by Neil Muller.

1068 type is specified. Patch by Brian Curtin.
1069
Antoine Pitrou905a2ff2010-01-31 22:47:27 +00001070- Issue #6939: Fix file I/O objects in the `io` module to keep the original
1071 file position when calling `truncate()`. It would previously change the
1072 file position to the given argument, which goes against the tradition of
1073 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1074
Antoine Pitroua32f9a22010-01-27 21:18:57 +00001075- Issue #7610: Reworked implementation of the internal
1076 :class:`zipfile.ZipExtFile` class used to represent files stored inside
1077 an archive. The new implementation is significantly faster and can
1078 be wrapped in a :class:`io.BufferedReader` object for more speedups.
1079 It also solves an issue where interleaved calls to `read()` and
1080 `readline()` give wrong results. Patch by Nir Aides.
1081
Jesse Noller1f0b6582010-01-27 03:36:01 +00001082- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
1083 allowing for a maximum number of tasks within the pool to be completed by
1084 the worker before that worker is terminated, and a new one created to
1085 replace it.
1086
Benjamin Petersond6326642010-01-27 02:25:58 +00001087- Issue #7792: Registering non-classes to ABCs raised an obscure error.

Tarek Ziadéacafc2d2009-11-29 22:24:57 +00001195- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
1196 ownership when the group is not forced, because the group may be different

Nick Coghlan260bd3e2009-11-16 06:49:25 +00001243- Issue #6816: runpy now provides a run_path function that allows Python code
1244 to execute file paths that refer to source or compiled Python files as well
1245 as zipfiles, directories and other valid sys.path entries that contain a
1246 __main__.py file. This allows applications that run other Python scripts to
1247 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001266 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001267 recursive locks as fast as regular non-recursive locks (previously,
1268 they were slower by 10x to 15x).

1288 reading from stdin so that existing input does not confuse it and
1289 lead to incorrect entry or an IOError. It also properly flushes it
1290 afterwards to avoid the terminal echoing the input afterwards on
1291 OSes such as Solaris.

Ronald Oussorenb6ee4f52010-07-23 13:53:51 +00001477- Issue #7900: The getgroups(2) system call on MacOSX behaves rather oddly
1478 compared to other unix systems. In particular, os.getgroups() does
1479 not reflect any changes made using os.setgroups() but basicly always
1480 returns the same information as the id command.
1481
1482 os.getgroups() can now return more than 16 groups on MacOSX.
1483
Martin v. Löwisc9e1c7d2010-07-23 12:16:41 +00001484- Issue #6095: Make directory argument to os.listdir optional.
1485
Mark Dickinsone26660f2010-07-18 07:48:20 +00001486- Issue #9277: Fix bug in struct.pack for bools in standard mode
1487 (e.g., struct.pack('>?')): if conversion to bool raised an exception
Mark Dickinson1b3c2622010-07-18 08:03:10 +00001488 then that exception wasn't properly propagated on machines where
1489 char is unsigned.
Mark Dickinsone26660f2010-07-18 07:48:20 +00001490
Alexander Belopolskyd92f0402010-07-17 22:50:45 +00001491- Issue #5180: Fixed a bug that prevented loading 2.x pickles in 3.x
1492 python when they contain instances of old-style classes.
1493
Mark Dickinson8e0c9962010-07-11 17:38:24 +00001494- Issue #9165: Add new functions math.isfinite and cmath.isfinite, to
1495 accompany existing isinf and isnan functions.
1496
Brian Curtind40e6f72010-07-08 21:39:08 +00001497- Issue #1578269: Implement os.symlink for Windows 6.0+. Patch by
1498 Jason R. Coombs
1499
Benjamin Petersona9800a82010-07-07 19:04:48 +00001500- In struct.pack, correctly propogate exceptions from computing the truth of an
1501 object in the '?' format.
1502
Alexander Belopolskya11d8c02010-07-06 23:19:45 +00001503- Issue #9000: datetime.timezone objects now have eval-friendly repr.
1504
Benjamin Petersonf751bc92010-07-02 13:46:42 +00001505- In the math module, correctly lookup __trunc__, __ceil__, and __floor__ as
1506 special methods.
Benjamin Peterson8bb9cde2010-07-01 15:16:55 +00001507
Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001508- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1509 10,000. Prior to this change, timezone adjustment in utctimetuple()
1510 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1511 raised in these edge cases.
1512
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001513- Issue #6641: The ``datetime.strptime`` method now supports the
1514 ``%z`` directive. When the ``%z`` directive is present in the
1515 format string, an aware ``datetime`` object is returned with
1516 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1517 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1518 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1519 without ``%z`` is discarded.
1520
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001521- Issue #5094: The ``datetime`` module now has a simple concrete class
1522 implementing ``datetime.tzinfo`` interface. Instances of the new
1523 class, ``datetime.timezone``, return fixed name and UTC offset from
1524 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1525 method always returns ``None``. A class attribute, ``utc`` contains
1526 an instance representing the UTC timezone. Original patch by Rafe
1527 Kaplan.
1528
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001529- Issue #8973: Add __all__ to struct module; this ensures that
1530 help(struct) includes documentation for the struct.Struct class.
1531
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001532- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001533 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001534 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00001535
Stefan Kraha3ac44e2010-06-08 14:00:52 +00001536- Issue #7384: If the system readline library is linked against ncurses,
1537 the curses module must be linked against ncurses as well. Otherwise it
1538 is not safe to load both the readline and curses modules in an application.
1539
Brian Curtin60853212010-05-26 17:43:50 +00001540- Issue #2810: Fix cases where the Windows registry API returns
1541 ERROR_MORE_DATA, requiring a re-try in order to get the complete result.
1542
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001543- Issue #8692: Optimize math.factorial: replace the previous naive
1544 algorithm with an improved 'binary-split' algorithm that uses fewer
1545 multiplications and allows many of the multiplications to be
1546 performed using plain C integer arithmetic instead of PyLong
1547 arithmetic. Also uses a lookup table for small arguments.
1548
Mark Dickinson85eacea2010-05-10 16:27:45 +00001549- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1550 overflow checks in the audioop module.
1551
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001552- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1553 calculating with integer arithmetic instead of float arithmetic internally):
1554 the result is now always correctly rounded, and is equivalent to td /
1555 timedelta(seconds=1).
1556
Mark Dickinson7c186e22010-04-20 22:32:49 +00001557- Issue #2706: Allow division of a timedelta by another timedelta:
1558 timedelta / timedelta, timedelta % timedelta, timedelta // timedelta
1559 and divmod(timedelta, timedelta) are all supported.
1560
Victor Stinnerfebecd82010-04-16 12:07:30 +00001561- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
1562
Mark Dickinsonc5935772010-04-03 15:54:36 +00001563- Issue #8300: When passing a non-integer argument to struct.pack with any
1564 integer format code, struct.pack first attempts to convert the non-integer
1565 using its __index__ method. If that method is non-existent or raises
1566 TypeError it goes on to try the __int__ method, as described below.
1567
Matthias Klosea8349752010-03-15 13:25:28 +00001568- Issue #8142: Update libffi to the 3.0.9 release.
1569
Matthias Klose9550aa12010-03-15 12:49:46 +00001570- Issue #6949: Allow the _dbm extension to be built with db 4.8.x.
1571

1573 handling.
1574
Martin v. Löwis3afc62e2010-02-18 16:27:43 +00001575- Stop providing crtassem.h symbols when compiling with Visual Studio 2010, as

1592 Unicode category 'Nd' (Number, Decimal Digit). Previously it also
1593 matched characters with category 'No'.
1594
Alexandre Vassalottiad077152009-07-15 17:49:23 +00001595- Issue #4509: Array objects are no longer modified after an operation

Florent Xicluna3f88c0e2010-03-19 14:40:31 +00001766- Issue #7783: test.support.open_urlresource invalidates the outdated files
1767 from the local cache.
Florent Xiclunaf089fd62010-03-19 14:25:03 +00001768
Florent Xiclunab14930c2010-03-13 15:26:44 +00001769- Issue #7849: Now the utility ``check_warnings`` verifies if the warnings are
1770 effectively raised.
1771
Florent Xiclunac9c79782010-03-08 12:24:53 +00001772- The four path modules (genericpath, macpath, ntpath, posixpath) share a

1783
Ezio Melotti184bdfb2010-02-18 09:37:05 +00001784- Issue #7712: test.support gained a new `temp_cwd` context manager which is
1785 now also used by regrtest to run all the tests in a temporary directory.
1786 The original CWD is saved in `support.SAVEDCWD`.
1787 Thanks to Florent Xicluna who helped with the patch.

R. David Murraye9e95932010-02-06 05:00:15 +00001795
R. David Murray445448c2009-12-20 17:28:31 +00001796- Issue #7376: instead of running a self-test (which was failing) when called
1797 with no arguments, doctest.py now gives a usage message.

1800
R. David Murray596da442009-12-14 23:06:11 +00001801- Issue #7498: test_multiprocessing now uses test.support.find_unused_port
R. David Murray83396232009-12-14 22:45:15 +00001802 instead of a hardcoded port number in test_rapid_restart.

Victor Stinnere125f132010-05-15 21:04:43 +00001804- Issue #7431: use TESTFN in test_linecache instead of trying to create a
R. David Murrayba311052009-12-04 00:09:14 +00001805 file in the Lib/test directory, which might be read-only for the
1806 user running the tests.
1807
R. David Murray35768ad2009-11-15 00:23:21 +00001808- Issue #7324: add a sanity check to regrtest argument parsing to
1809 catch the case of an option with no handler.
1810
R. David Murray7dc72cc2009-11-14 16:13:02 +00001811- Issue #7312: Add a -F flag to run the selected tests in a loop until
1812 a test fails. Can be combined with -j.
1813
Antoine Pitrou060cee22009-11-13 16:29:04 +00001814- Issue #6551: test_zipimport could import and then destroy some modules of
1815 the encodings package, which would make other tests fail further down
1816 the road because the internally cached encoders and decoders would point
1817 to empty global variables.
1818
Antoine Pitrou941ee882009-11-11 20:59:38 +00001819- Issue #7295: Do not use a hardcoded file name in test_tarfile.

1825 tests instead of tempfile.tempdir. This prevents the tests from sharing state
1826 between concurrent executions on the same system.
1827
Brett Cannon0ae45112009-11-05 01:17:22 +00001828- Issue #7248: In importlib.test.source.util a try/finally block did not make
1829 sure that some referenced objects actually were created in the block before
1830 calling methods on the object.
1831
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001832- Issue #7222: Make thread "reaping" more reliable so that reference
1833 leak-chasing test runs give sensible results. The previous method of
1834 reaping threads could return successfully while some Thread objects were
1835 still referenced. This also introduces a new private function:
1836 :func:`_thread._count()`.
1837
R. David Murray27144602009-10-19 15:26:16 +00001838- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1839 longer runs the risk of causing the worker thread to fail.
1840
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001841- Issue #7055: test___all__ now greedily detects all modules which have an
1842 __all__ attribute, rather than using a hardcoded and incomplete list.
1843
R. David Murray0bc11ae2009-10-18 22:18:17 +00001844- Issue #7058: Added save/restore for things like sys.argv and cwd to
1845 runtest_inner in regrtest, with warnings if the called test modifies them,
1846 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001847
Mark Dickinson2e304402009-10-04 18:43:54 +00001848- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1849
Brett Cannon3c273842009-07-20 00:14:29 +00001850- Fixed tests in importlib.test.source.test_abc_loader that were masking
1851 the proper exceptions that should be raised for missing or improper code
1852 object bytecode.
1853
Brett Cannonb49c70c2009-07-15 04:08:33 +00001854- Removed importlib's custom test discovery code and switched to
1855 unittest.TestLoader.discover().

1863 added to the `Tools/` directory. They were previously living in the
1864 sandbox.

Benjamin Peterson14a3dd72009-05-25 00:51:58 +00002039- In unittest, using a skipping decorator on a class is now equivalent to
2040 skipping every test on the class. The ClassTestSuite class has been removed.
2041
Martin v. Löwis70ccd162009-05-24 19:47:22 +00002042- Issue #6050: Don't fail extracting a directory from a zipfile if
2043 the directory already exists.
2044
Antoine Pitrou61f77b52009-05-24 15:46:13 +00002045- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
2046 than an int, which makes some operations possible under 64-bit Linux (e.g.
2047 DN_MULTISHOT with F_NOTIFY).
2048
Antoine Pitrou716c4442009-05-23 19:04:03 +00002049- Issue #5761: Add the name of the underlying file to the repr() of various

2053 by Musashi Tamura, tests by Marcin Bachry.
2054
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00002055- Issue #1983: Fix functions taking or returning a process identifier to use
2056 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
2057 a process identifier type wider than the standard C integer type.
2058
R. David Murray87e20742009-05-23 01:30:26 +00002059- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

2068
Antoine Pitrou2ca24f02009-05-14 21:30:46 +00002069- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
2070
Antoine Pitroue4501852009-05-14 18:55:55 +00002071- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
2072 library. This means, for example, that opening an UTF-16 text file in
2073 append mode doesn't add a BOM at the end of the file if the file isn't
2074 empty.
2075
R. David Murray74b89242009-05-13 17:33:03 +00002076- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
2077 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
2078 corrects a pydoc regression.
2079
R. David Murray99352742009-05-07 18:24:38 +00002080- Issue 5955: aifc's close method did not close the file it wrapped,
2081 now it does. This also means getfp method now returns the real fp.
2082

2084------------
2085
2086- Issue #6047: fullinstall has been removed because Python 3's executable will

Benjamin Petersonbd35b032009-04-04 23:16:41 +00002123
2124Core and Builtins
2125-----------------
2126
Mark Dickinson865e01a2009-05-07 16:37:01 +00002127- Issue #5914: Add new C API function PyOS_string_to_double, and
2128 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2129
Eric Smith741191f2009-05-06 13:08:15 +00002130- Issue #3382: float.__format__, complex.__format__, and %-formatting
2131 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2132 affects nan -> NAN and inf -> INF.
2133
Mark Hammond5a607a32009-05-06 08:04:54 +00002134- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2135 in all operations, including splitdrive, split, etc. splitunc() now issues
2136 a PendingDeprecation warning.
2137
Eric Smith63376222009-05-05 14:04:18 +00002138- Issue #5920: For float.__format__, change the behavior with the
2139 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2140 to be like 'g' but with at least one decimal point and with a
2141 default precision of 12. Previously, the behavior the same but with
2142 a default precision of 6. This more closely matches str(), and
2143 reduces surprises when adding alignment flags to the empty
2144 presentation type. This also affects the new complex.__format__ in
2145 the same way.
2146
Martin v. Löwis011e8422009-05-05 04:43:17 +00002147- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2148
R. David Murrayb18500d2009-05-04 22:59:07 +00002149- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2150 shadowed by classtype's, even if it was None. property now
2151 inserts the __doc__ into the subclass instance __dict__.
2152
Antoine Pitrou244651a2009-05-04 18:56:13 +00002153- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2154 sequences. Patch by Nick Barnes and Victor Stinner.
2155
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002156- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002157
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002158- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2159 received a new method, detach(). detach() disconnects the underlying stream
2160 from the buffer or text IO and returns it.
2161
Mark Dickinson33841c32009-05-01 15:37:04 +00002162- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2163 floats with absolute value over 1e50. Also remove length
2164 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2165 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002166
Eric Smith741191f2009-05-06 13:08:15 +00002167- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002168 format(complex(1, 2./3), '.5') now produces a sensible result.
2169
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002170- Issue #5864: Fix empty format code formatting for floats so that it
2171 never gives more than the requested number of significant digits.
2172
Eric Smith6dc46f52009-04-27 20:39:49 +00002173- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2174 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2175
Eric Smithcc32a112009-04-26 21:35:14 +00002176- Issue #5835: Deprecate PyOS_ascii_formatd.
2177
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002178- Issue #4971: Fix titlecase for characters that are their own
2179 titlecase, but not their own uppercase.
2180
Benjamin Peterson193152c2009-04-25 01:08:45 +00002181- Issue #5283: Setting __class__ in __del__ caused a segfault.
2182
Mark Dickinsonad476da2009-04-23 19:14:16 +00002183- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2184 z involves nans, infs or negative zeros.
2185
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002186- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002187
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002188- Issue #1869 (and many duplicates): make round(x, n) correctly
2189 rounded for a float x, by using the decimal <-> binary conversions
2190 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2191 consistently agrees with format(x, '.2f').
2192
Benjamin Petersonae937c02009-04-18 20:54:08 +00002193- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2194 some builtin types.
2195
Eric Smith0923d1d2009-04-16 20:16:10 +00002196- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2197
Eric Smith35e84722009-04-16 20:21:28 +00002198- Issue #5515: str.format() type 'n' combined with commas and leading
2199 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002200
2201- Implement PEP 378, Format Specifier for Thousands Separator, for
2202 floats.
2203
Mark Dickinson3370cce2009-04-17 22:40:53 +00002204- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002205 1e11, not 1e12. This avoids printing 13 significant digits in
2206 situations where only 12 of them are correct. Example problem
2207 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2208 long time.)
2209
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002210- Issue #1580: On most platforms, use a 'short' float repr: for a
2211 finite float x, repr(x) now outputs a string based on the shortest
2212 sequence of decimal digits that rounds to x. Previous behaviour was
2213 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002214 Another minor difference is that the new repr switches to
2215 exponential notation at 1e16 instead of the previous 1e17; this
2216 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002217
2218 There's a new sys attribute sys.float_repr_style, which takes
2219 the value 'short' to indicate that we're using short float repr,
2220 and 'legacy' if the short float repr isn't available for one
2221 reason or another.
2222
2223 The float repr change involves incorporating David Gay's 'perfect
2224 rounding' code into the Python core (it's in Python/dtoa.c). As a
2225 secondary consequence, all string-to-float and float-to-string
2226 conversions (including all float formatting operations) will be
2227 correctly rounded on these platforms.
2228
2229 See issue 1580 discussions for details of platforms for which
2230 this change does not apply.
2231
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002232- Issue #5759: float() didn't call __float__ on str subclasses.
2233
Georg Brandlabc38772009-04-12 15:51:51 +00002234- The string.maketrans() function is deprecated; there is a new static method
2235 maketrans() on the bytes and bytearray classes. This removes confusion about
2236 the types string.maketrans() is supposed to work with, and mirrors the
2237 methods available on the str class.
2238
R. David Murraydc6da8a2009-04-09 22:16:43 +00002239- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2240 its clarity and its speed.
2241
Matthias Klose091c7b12009-04-07 13:24:27 +00002242- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2243 to avoid compiler warnings.
2244
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002245- Issue #3739: The unicode-internal encoder now reports the number of characters
2246 consumed like any other encoder (instead of the number of bytes).

2404
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002405- Issue #4688: Add a heuristic so that tuples and dicts containing only
2406 untrackable objects are not tracked by the garbage collector. This can
2407 reduce the size of collections and therefore the garbage collection overhead
2408 on long-running programs, depending on their particular use of datatypes.

2477
Lars Gustäbel42e00912009-03-22 20:34:29 +00002478- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2479 forever on incomplete input. That caused tarfile.open() to hang when used
2480 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2481 partial bzip2 compressed data.

2598 flag to work properly. Furthermore, when specifying -u, the text stdout
2599 and stderr streams have line-by-line buffering enabled (the default being
2600 to buffer arbitrary chunks of data).
2601
Raymond Hettinger35631532009-01-09 03:58:09 +00002602- The internal table, _PyLong_DigitValue, is now an array of unsigned chars

2605
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002606- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2607 an existing .py counterpart, override the co_filename attributes of all
2608 code objects if the original filename is obsolete (which can happen if the
2609 file has been renamed, moved, or if it is accessed through different paths).
2610 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2611
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002612- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2613 one byte. Also fixes the meaning of len() so that it returns the number of
2614 items, rather than the size in bytes.
2615
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002616- Issue #4075: Use OutputDebugStringW in Py_FatalError.

2684 of using the replace error handler in PyUnicode_DecodeUTF8().

3003
Antoine Pitrou08838b62009-01-21 00:55:13 +00003004- Issue #5008: When a file is opened in append mode with the new IO library,
3005 do an explicit seek to the end of file (so that e.g. tell() returns the
3006 file size rather than 0). This is consistent with the behaviour of the
