11
12Core and Builtins
13-----------------
14
Benjamin Petersonccabcd42010-07-07 20:54:01 +000015- Issue #8413: structsequence now subclasses tuple.
16
Ezio Melotti57221d02010-07-01 07:32:02 +000017- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
18 start byte and the continuation byte(s) are now considered invalid, instead
19 of the number of bytes specified by the start byte.
20 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
21 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
22 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
23 Previous versions returned a single u'\ufffd'.
24
Mark Dickinson50b79a82010-06-30 11:13:36 +000025- Issue #9011: A negated imaginary literal (e.g., "-7j") now has real
26 part -0.0 rather than 0.0. So "-7j" is now exactly equivalent to
27 "-(7j)".
28
Benjamin Peterson88968ad2010-06-25 19:30:21 +000029- Be more specific in error messages about positional arguments.
30
Victor Stinner4aae1eb2010-06-24 22:08:25 +000031- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
32 objects, as described in the documentation.
33
Victor Stinner0fe25a42010-06-17 23:08:50 +000034- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000035 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
36 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000037
Mark Dickinsond35a32e2010-06-17 12:33:22 +000038- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
39 compilation code dealing with unary minus applied to a constant.
40 The removed code was mutating the ST, causing a second compilation
41 to fail.
42
Victor Stinner554f3f02010-06-16 23:33:54 +000043- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
44 mode raises unicode errors. The encoder only supports "strict" and "replace"
45 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000046 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000047
Victor Stinner25e8ec42010-06-25 00:02:38 +000048- Issue #8850: Remove "w" and "w#" formats from PyArg_Parse*() functions, use
49 "w*" format instead. Add tests for "w*" format.
50
Victor Stinner06e49dd2010-06-13 18:21:50 +000051- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
52 formats if the string contains a null byte/character. Write unit tests for
53 string formats.
54
Nick Coghlan5e76e942010-06-12 13:42:46 +000055- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
56 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
57 location of the raised exception.
58
Victor Stinner313a1202010-06-11 23:56:51 +000059- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
60 filenames and enable os.fsencode().
61
Benjamin Peterson285a6892010-06-22 19:21:52 +000062- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
63
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000064- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
65 the interpreter with characters outside the Basic Multilingual Plane
66 (higher than 0x10000).
67
Mark Dickinsonc7301312010-06-10 16:05:10 +000068- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
69 raise TypeError instead of giving a DeprecationWarning when a float
70 is parsed using the 'L' code (for long long). (All other integer
71 codes already raise TypeError in this case.)
72
Victor Stinner600d3be2010-06-10 12:00:55 +000073- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
74 enable shortcuts for upper case encoding name. Add also a shortcut for
75 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
76
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000077- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
78 doesn't support "char buffer" anymore in Python3.
79
80- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
81 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
82 like bytearray.
83
Victor Stinner33109a12010-05-28 21:55:10 +000084- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
85 used anymore and it was never documented.
86
Benjamin Peterson95304522010-06-08 14:57:22 +000087- In the str.format(), raise a ValueError when indexes to arguments are too
88 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000089
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000090- Issue #2844: Make int('42', n) consistently raise ValueError for
91 invalid integers n (including n = -909).
92
Mark Dickinsondc787d22010-05-23 13:33:13 +000093- Issue #8188: Introduce a new scheme for computing hashes of numbers
94 (instances of int, float, complex, decimal.Decimal and
95 fractions.Fraction) that makes it easy to maintain the invariant
96 that hash(x) == hash(y) whenever x and y have equal value.
97
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000098- Issue #8748: Fix two issues with comparisons between complex and integer
99 objects. (1) The comparison could incorrectly return True in some cases
100 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
101 (2) The comparison raised an OverflowError for large integers, leading
102 to unpredictable exceptions when combining integers and complex objects
103 in sets or dicts.
104
Victor Stinner7d79b8b2010-05-19 20:40:50 +0000105- Issue #8766: Initialize _warnings module before importing the first module.
106 Fix a crash if an empty directory called "encodings" exists in sys.path.
107
Victor Stinner9ca9c252010-05-19 16:53:30 +0000108- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
109 encoding and surrogateespace error handler instead of the locale encoding to
110 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
111
Victor Stinner372ac5e2010-05-17 01:26:01 +0000112- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
113 (instead of strict) error handler to escape surrogates
114
Victor Stinnerae6265f2010-05-15 16:27:27 +0000115- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
116 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +0000117 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
118 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000119
Victor Stinner59e62db2010-05-15 13:14:32 +0000120- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
121 error handler, not only the default error handler (strict)
122
Victor Stinnerb744ba12010-05-15 12:27:16 +0000123- Issue #8610: Load file system codec at startup, and display a fatal error on
124 failure. Set the file system encoding to utf-8 (instead of None) if getting
125 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
126
Victor Stinner0964ee12010-04-30 16:48:45 +0000127- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
128 PyUnicode_FromString() to support surrogates in the filename and use the
129 right encoding
130
Georg Brandl8569e582010-05-19 20:57:08 +0000131- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
132
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000133- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
134
Benjamin Petersonfb886362010-04-24 18:21:17 +0000135- Issue #8419: Prevent the dict constructor from accepting non-string keyword
136 arguments.
137
Victor Stinner14284c22010-04-23 12:02:30 +0000138- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
139 indirectly Python signal handlers anymore because mywrite() ignores
140 exceptions (KeyboardInterrupt)
141
Victor Stinner31be90b2010-04-22 19:38:16 +0000142- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
143 unicode string (eg. backslashreplace)
144
Victor Stinnerdcb24032010-04-22 12:08:36 +0000145- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
146 you have to convert your bytearray filenames to bytes
147
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000148- Issue #7332: Remove the 16KB stack-based buffer in
149 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
150 benefit compared to the dynamic memory allocation fallback. Patch by
151 Charles-François Natali.
152
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000153- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
154 passed to bytes or bytearray.
155
Philip Jenvey0805ca32010-04-07 04:04:10 +0000156- Issue #7301: Add environment variable $PYTHONWARNINGS.
157
Benjamin Petersond856ab62010-04-06 21:55:16 +0000158- Issue #8329: Don't return the same lists from select.select when no fds are
159 changed.
160
Mark Dickinson3318d292010-04-06 16:53:17 +0000161- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
162 on 64-bit machines. The shift count for either left or right shift is
163 permitted to be up to sys.maxsize.
164
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000165- Ensure that tokenization of identifiers is not affected by locale.

172 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000173
Victor Stinner120c2122010-03-25 00:30:28 +0000174- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
175 is unknown
176
Victor Stinner808fc0a2010-03-22 12:50:40 +0000177- Issue #1583863: An str subclass can now override the __str__ method
178
Mark Dickinsond59b4162010-03-13 11:34:40 +0000179- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
180 PyMemberDefs could produce an internal error; raise TypeError instead.
181
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000182- Issue #7845: Rich comparison methods on the complex type now return
183 NotImplemented rather than raising a TypeError when comparing with an
184 incompatible type; this allows user-defined classes to implement their own
185 comparisons with complex.
186
Victor Stinner52f6dd72010-03-12 14:45:56 +0000187- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
188 (SIGINT). If an error occurs while importing the site module, the error is
189 printed and Python exits. Initialize the GIL before importing the site
190 module.
191
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000192- Issue #7173: Generator finalization could invalidate sys.exc_info().

195 a fatal error in low memory condition.
196
Victor Stinner6aa278e2010-03-03 00:18:49 +0000197- Issue #7820: The parser tokenizer restores all bytes in the right if
198 the BOM check fails.
199
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000200- Handle errors from looking up __prepare__ correctly.
201
Larry Hastings1373a072010-02-24 22:49:58 +0000202- Issue #5939: Add additional runtime checking to ensure a valid capsule
203 in Modules/_ctypes/callproc.c.
204
Eric Smith0facd772010-02-24 15:42:29 +0000205- Issue #7309: Fix unchecked attribute access when converting
206 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
207 strings.
208
Eric Smithabb28c62010-02-23 00:22:24 +0000209- Issue #6902: Fix problem with built-in types format incorrectly with

218 deprecations.
219
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000220- Issue #7385: Fix a crash in `MemoryView_FromObject` when
221 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
222
Mark Dickinsonbc099642010-01-29 17:27:24 +0000223- Issue #7788: Fix an interpreter crash produced by deleting a list
224 slice with very large step value.
225
Eric Smithf7bb5782010-01-27 00:44:57 +0000226- Issue #7766: Change sys.getwindowsversion() return value to a named
227 tuple and add the additional members returned in an OSVERSIONINFOEX
228 structure. The new members are service_pack_major, service_pack_minor,
229 suite_mask, and product_type.
230
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000231- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
232 could crash in many places because of the PyByteArray_AS_STRING() macro
233 returning NULL. The macro now returns a statically allocated empty
234 string instead.
235
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000236- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
237 where the right hand operand is a set of constants, by turning the set into
238 a frozenset and pre-building it as a constant. The comparison operation
239 is made against the constant instead of building a new set each time it is
240 executed (a similar optimization already existed which turned a list of
241 constants into a pre-built tuple). Patch and additional tests by Dave
242 Malcolm.
243
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000244- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
245 methods of bytes, bytearray and unicode objects by using a common
246 implementation based on stringlib's fast search. Patch by Florent Xicluna.
247
Mark Dickinson45b63652010-01-16 18:10:25 +0000248- Issue #7632: Fix various str -> float conversion bugs present in 2.7
249 alpha 2, including: (1) a serious 'wrong output' bug that could
250 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
251 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000252 strings corresponding to subnormal values, (3) a memory leak for
253 some values large enough to cause overflow, and (4) a number of
254 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000255
Benjamin Petersonaea44282010-01-04 01:10:28 +0000256- The __complex__ method is now looked up on the class of instances to make it
257 consistent with other special methods.

266 negative zero) in ** operator. The behaviour now conforms to that
267 described in C99 Annex F.
268
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000269- Issue #1811: improve accuracy and cross-platform consistency for
270 true division of integers: the result of a/b is now correctly
271 rounded for ints a and b (at least on IEEE 754 platforms), and in
272 particular does not depend on the internal representation of an int.
273
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000274- Issue #6834: replace the implementation for the 'python' and 'pythonw'
275 executables on OSX.
276
277 These executables now work properly with the arch(1) command:
278 ``arch -ppc python`` will start a universal binary version of python
279 in PPC mode (unlike previous releases).
280
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000281- Issue #7466: segmentation fault when the garbage collector is called

297
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000298- Issue #7298: fixes for range and reversed(range(...)). Iteration
299 over range(a, b, c) incorrectly gave an empty iterator when a, b and
300 c fit in C long but the length of the range did not. Also fix
301 several cases where reversed(range(a, b, c)) gave wrong results, and
302 fix a refleak for reversed(range(a, b, c)) with large arguments.
303
Raymond Hettingerfc438512009-11-01 20:55:33 +0000304- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitroub5218772010-05-21 09:56:06 +0000618 several ``OP_*`` constants to the `ssl` module. This allows to selectively
619 disable protocol versions, when used in combination with `PROTOCOL_SSLv23`.
620
Tarek Ziadé06710a82010-05-19 22:25:00 +0000621- Issue #8759: Fixed user paths in sysconfig for posix and os2 schemes.
622
Victor Stinner2ca03c12010-05-19 17:00:07 +0000623- Issue #8663: distutils.log emulates backslashreplace error handler. Fix
624 compilation in a non-ASCII directory if stdout encoding is ASCII (eg. if
625 stdout is not a TTY).
626
Victor Stinnerb745a742010-05-18 17:17:23 +0000627- Issue #8513: os.get_exec_path() supports b'PATH' key and bytes value.
628 subprocess.Popen() and os._execvpe() support bytes program name. Add
629 os.supports_bytes_environ flag: True if the native OS type of the environment
630 is bytes (eg. False on Windows).
631
Lars Gustäbel1465cc22010-05-17 18:02:50 +0000632- Issue #8633: tarfile is now able to read and write archives with "raw" binary

646 the zlib itself doesn't give any detailed explanation.
647
Mark Dickinson81fece22010-05-11 13:34:35 +0000648- The audioop module now supports sound fragments of length greater
649 than 2**31 bytes on 64-bit machines, and is PY_SSIZE_T_CLEAN.
650
Giampaolo Rodolàbd576b72010-05-10 14:53:29 +0000651- Issue #4972: Add support for the context manager protocol to the ftplib.FTP
652 class.

655 given.
656
Victor Stinner449c4662010-05-08 11:10:09 +0000657- Issue #8514: Add os.fsencode() function (Unix only): encode a string to bytes
658 for use in the file system, environment variables or the command line.
659
Antoine Pitrou89562712010-05-07 17:04:02 +0000660- Issue #8571: Fix an internal error when compressing or decompressing a

662 objects.
663
Benjamin Peterson225168e2010-05-06 22:29:53 +0000664- Issue #8603: Support bytes environmental variables on Unix: Add os.environb
665 mapping and os.getenvb() function. os.unsetenv() encodes str argument to the
666 file system encoding with the surrogateescape error handler (instead of
667 utf8/strict) and accepts bytes. posix.environ keys and values are now bytes.

Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000669- Issue #8573: asyncore _strerror() function might throw ValueError.
670
Victor Stinnere125f132010-05-15 21:04:43 +0000671- Issue #8483: asyncore.dispatcher's __getattr__ method produced confusing
672 error messages when accessing undefined class attributes because of the cheap
673 inheritance with the underlying socket object.
Giampaolo Rodolà8d2dc852010-05-06 18:06:30 +0000674 The cheap inheritance has been deprecated.
675

677 Patch by Tres Seaver.
678
Victor Stinnerde629d42010-05-05 21:43:57 +0000679- Issue #8390: tarfile uses surrogateespace as the default error handler
680 (instead of replace in read mode or strict in write mode)
681

686
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000687- Issue #8567: Fix precedence of signals in Decimal module: when a
688 Decimal operation raises multiple signals and more than one of those
689 signals is trapped, the specification determines the order in which
690 the signals should be handled. In many cases this order wasn't
691 being followed, leading to the wrong Python exception being raised.
692
Antoine Pitrou6be88762010-05-03 16:48:20 +0000693- Issue #7865: The close() method of :mod:`io` objects should not swallow

695 close() several times is supported. Patch by Pascal Chambon.
696
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000697- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
698 gc.DEBUG_STATS.
699
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000700- Issue #8354: The siginterrupt setting is now preserved for all signals,
701 not just SIGCHLD.
702
Georg Brandl25106ce2010-05-21 21:49:47 +0000703- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000704 webbrowser.get("safari").
705
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000706- Issue #8464: tarfile no longer creates files with execute permissions set
707 when mode="w|" is used.
708
Antoine Pitroubf043492010-04-29 10:11:46 +0000709- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
710 of the Linux kernel. Patch by Yaniv Aknin.

Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000714- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
715 It should correctly return an empty response now.
716
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000717- Issue #8546: Reject None given as the buffering argument to _pyio.open.
718
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000719- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
720 Sridhar Ratnakumar.
721
R. David Murrayad78d152010-04-27 02:45:53 +0000722- Issue #6656: fix locale.format_string to handle escaped percents
723 and mappings.
724
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000725- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
726 where the method could block indefinitely if called just before the
727 event loop started running. This also fixes the occasional freezes
728 witnessed in test_httpservers.
729
Antoine Pitrou40f08742010-04-24 22:04:40 +0000730- Issue #8524: When creating an SSL socket, the timeout value of the
731 original socket wasn't retained (instead, a socket with a positive timeout
732 would be turned into a non-blocking SSL socket).
733
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000734- Issue #5103: SSL handshake would ignore the socket timeout and block
735 indefinitely if the other end didn't respond.
736
737- The do_handshake() method of SSL objects now adjusts the blocking mode of
738 the SSL structure if necessary (as other methods already do).
739
Victor Stinner13bb71c2010-04-23 21:41:56 +0000740- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
741 and bytes strings for environment keys and values
742
Victor Stinner4d078042010-04-23 19:28:32 +0000743- Issue #8467: Pure Python implementation of subprocess encodes the error

748
Sean Reifscheider13daf122010-04-23 09:29:52 +0000749- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
750 the string "python" as the *ident*. openlog() arguments are all optional
751 and keywords.
752
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000753- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
754 a non-infinite timeout. Also make that method friendlier with applications
755 wanting to continue using the socket in clear-text mode, by disabling
756 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
757
Antoine Pitrou7062db82010-04-22 13:30:10 +0000758- Issue #8496: make mailcap.lookup() always return a list, rather than an
759 iterator. Patch by Gregory Nofi.
760
Victor Stinner35466c52010-04-22 11:23:23 +0000761- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
762 collation name contains a surrogate character.
763
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000764- Issue #8484: Load all ciphers and digest algorithms when initializing
765 the _ssl extension, such that verification of some SSL certificates
766 doesn't fail because of an "unknown algorithm".
767
Tarek Ziadéfb437512010-04-20 08:57:33 +0000768- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
769
Victor Stinnere125f132010-05-15 21:04:43 +0000770- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000771 shutil.copytree.
772
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000773- Issue #4814: timeout parameter is now applied also for connections resulting
774 from PORT/EPRT commands.
775
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000776- Issue #8463: added missing reference to bztar in shutil's documentation.
777
Ronald Oussoren84151202010-04-18 20:46:11 +0000778- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
779 (as long as the user didn't specify 'automatic proxy configuration').
780
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000781- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
782 code as stated in RFC-959 at chapter 5.4.
783
Victor Stinner738446f02010-04-18 00:00:44 +0000784- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
785 surrogates.
786
Antoine Pitrou0454af92010-04-17 23:51:58 +0000787- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000788 `threading.Semaphore` objects. Original patch by Torsten Landschoff.

Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000790- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
791 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
792
Victor Stinner0e59cc32010-04-16 23:49:32 +0000793- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
794 the current working directory.
795
Victor Stinner5bfe1462010-04-16 13:28:05 +0000796- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
797 using backslashreplace error handler

806
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000807- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
808 module now takes an optional timeout argument in seconds. Timeout support
809 relies on the system threading library, so as to avoid a semi-busy wait
810 loop.
811
Victor Stinner485fb562010-04-13 11:07:24 +0000812- Issue #8383: pickle and pickletools use surrogatepass error handler when
813 encoding unicode as utf8 to support lone surrogates and stay compatible with
814 Python 2.x and 3.0
815
R. David Murrayb2416e52010-04-12 16:58:02 +0000816- Issue #7585: difflib context and unified diffs now place a tab between
817 filename and date, conforming to the 'standards' they were originally
818 designed to follow. This improves compatibility with patch tools.
819
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000820- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
821 character sets will now consistently use a Content-Transfer-Encoding of
822 7bit rather than sometimes being marked as 8bit.
823
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000824- Issue #8375: test_distutils now checks if the temporary directory are still
825 present before it cleans them.
826
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000827- Issue #8374: Update the internal alias table in the :mod:`locale` module
828 to cover recent locale changes and additions.
829
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000830- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
831 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
832 and `ssl.OPENSSL_VERSION_NUMBER`.
833
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000834- Add functools.total_ordering() and functools.cmp_to_key().
835
Mark Dickinson089b00c2010-04-03 15:51:03 +0000836- Issue #8257: The Decimal construct now accepts a float instance
837 directly, converting that float to a Decimal of equal value:
838
839 >>> Decimal(1.1)
840 Decimal('1.100000000000000088817841970012523233890533447265625')
841
Mark Dickinson98127c32010-04-03 11:18:52 +0000842- Issue #8294: The Fraction constructor now accepts Decimal and float
843 instances directly.
844
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000845- Issue #7279: Comparisons involving a Decimal signaling NaN now
846 signal InvalidOperation instead of returning False. (Comparisons
847 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
848 are now hashable; Decimal signaling NaNs remain unhashable.
849
850- Issue #2531: Comparison operations between floats and Decimal
851 instances now return a result based on the numeric values of the
852 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000853 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000854 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000855
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000856- Added a subtract() method to collections.Counter().
857
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000858- Issue #8233: When run as a script, py_compile.py optionally takes a single
859 argument `-` which tells it to read files to compile from stdin. Each line
860 is read on demand and the named file is compiled immediately. (Original
861 patch by Piotr Ożarowski).
862
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000863- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
864 form feed (0x0C) are now considered linebreaks, as specified in Unicode
865 Standard Annex #14. See issue #7643.
866 http://www.unicode.org/reports/tr14/
867
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000868- Comparisons using one of <, <=, >, >= between a complex instance and
869 a Fractions instance now raise TypeError instead of returning
870 True/False. This makes Fraction <=> complex comparisons consistent with
871 int <=> complex, float <=> complex, and complex <=> complex comparisons.
872
Antoine Pitrou39b35432010-03-23 00:25:54 +0000873- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

882 now silenced.
883
R. David Murrayca2edce2010-03-22 17:48:48 +0000884- Issue #7860: platform.uname now reports the correct 'machine' type

Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000914- The internals of the subprocess module on POSIX systems have been replaced
915 by an extension module (_posixsubprocess) so that the fork()+exec() can be
916 done safely without the possibility of deadlock in multithreaded applications.
917
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000918- subprocess.Popen now has restore_signals and start_new_session features.
919 The default of restore_signals=True is a new behavior compared to earlier
920 Python versions. This means that signals such as SIGPIPE are not ignored
921 by default in subprocesses launched by Python (Issue #1652).

1188 a connection with another process, rather than looping endlessly. The
1189 default timeout is 20 seconds, which should be amply sufficient for
1190 local connections.

Antoine Pitrou434736a2009-11-10 18:46:01 +00001203- Issue #3001: Add a C implementation of recursive locks which is used by
Victor Stinnere125f132010-05-15 21:04:43 +00001204 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001205 recursive locks as fast as regular non-recursive locks (previously,
1206 they were slower by 10x to 15x).

1223 failures on systems with slightly bogus mtime behaviour.
1224
Gregory P. Smith50467882009-11-01 18:42:17 +00001225- Issue #7246 & Issue #7208: getpass now properly flushes input before
1226 reading from stdin so that existing input does not confuse it and
1227 lead to incorrect entry or an IOError. It also properly flushes it
1228 afterwards to avoid the terminal echoing the input afterwards on
1229 OSes such as Solaris.

Brett Cannon69194272009-07-20 04:23:48 +00001361- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
1362 loaders that allow for modules to be executed. Both importlib.abc.PyLoader
1363 and PyPycLoader inherit from this class and provide implementations in
1364 relation to other methods required by the ABCs.
1365
Brett Cannon64ef00f2009-07-20 03:19:18 +00001366- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
1367 the documentation said it did even though the code in PyLoader relied on the

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001426- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1427 10,000. Prior to this change, timezone adjustment in utctimetuple()
1428 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1429 raised in these edge cases.
1430
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001431- Issue #6641: The ``datetime.strptime`` method now supports the
1432 ``%z`` directive. When the ``%z`` directive is present in the
1433 format string, an aware ``datetime`` object is returned with
1434 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1435 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1436 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1437 without ``%z`` is discarded.
1438
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001439- Issue #5094: The ``datetime`` module now has a simple concrete class
1440 implementing ``datetime.tzinfo`` interface. Instances of the new
1441 class, ``datetime.timezone``, return fixed name and UTC offset from
1442 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1443 method always returns ``None``. A class attribute, ``utc`` contains
1444 an instance representing the UTC timezone. Original patch by Rafe
1445 Kaplan.

Eric Smith741191f2009-05-06 13:08:15 +00002040- Issue #3382: float.__format__, complex.__format__, and %-formatting
2041 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
2042 affects nan -> NAN and inf -> INF.
2043
Mark Hammond5a607a32009-05-06 08:04:54 +00002044- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
2045 in all operations, including splitdrive, split, etc. splitunc() now issues
2046 a PendingDeprecation warning.
2047
Eric Smith63376222009-05-05 14:04:18 +00002048- Issue #5920: For float.__format__, change the behavior with the
2049 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2050 to be like 'g' but with at least one decimal point and with a
2051 default precision of 12. Previously, the behavior the same but with
2052 a default precision of 6. This more closely matches str(), and
2053 reduces surprises when adding alignment flags to the empty
2054 presentation type. This also affects the new complex.__format__ in
2055 the same way.
2056
Martin v. Löwis011e8422009-05-05 04:43:17 +00002057- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
2058
R. David Murrayb18500d2009-05-04 22:59:07 +00002059- Issue #5890: in subclasses of 'property' the __doc__ attribute was
2060 shadowed by classtype's, even if it was None. property now
2061 inserts the __doc__ into the subclass instance __dict__.
2062
Antoine Pitrou244651a2009-05-04 18:56:13 +00002063- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
2064 sequences. Patch by Nick Barnes and Victor Stinner.
2065
Martin v. Löwise0a2b722009-05-10 08:08:56 +00002066- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00002067
Benjamin Petersond2e0c792009-05-01 20:40:59 +00002068- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2069 received a new method, detach(). detach() disconnects the underlying stream
2070 from the buffer or text IO and returns it.
2071
Mark Dickinson33841c32009-05-01 15:37:04 +00002072- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2073 floats with absolute value over 1e50. Also remove length
2074 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2075 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00002076
Eric Smith741191f2009-05-06 13:08:15 +00002077- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002078 format(complex(1, 2./3), '.5') now produces a sensible result.
2079
Mark Dickinsond3ca5572009-04-29 18:47:07 +00002080- Issue #5864: Fix empty format code formatting for floats so that it
2081 never gives more than the requested number of significant digits.
2082
Eric Smith6dc46f52009-04-27 20:39:49 +00002083- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
2084 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
2085
Eric Smithcc32a112009-04-26 21:35:14 +00002086- Issue #5835: Deprecate PyOS_ascii_formatd.
2087
Martin v. Löwis71efeb72009-04-26 01:02:07 +00002088- Issue #4971: Fix titlecase for characters that are their own
2089 titlecase, but not their own uppercase.
2090
Benjamin Peterson193152c2009-04-25 01:08:45 +00002091- Issue #5283: Setting __class__ in __del__ caused a segfault.
2092
Mark Dickinsonad476da2009-04-23 19:14:16 +00002093- Issue #5816: complex(repr(z)) now recovers z exactly, even when
2094 z involves nans, infs or negative zeros.
2095
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002096- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002097
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002098- Issue #1869 (and many duplicates): make round(x, n) correctly
2099 rounded for a float x, by using the decimal <-> binary conversions
2100 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2101 consistently agrees with format(x, '.2f').
2102
Benjamin Petersonae937c02009-04-18 20:54:08 +00002103- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2104 some builtin types.
2105
Eric Smith0923d1d2009-04-16 20:16:10 +00002106- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2107
Eric Smith35e84722009-04-16 20:21:28 +00002108- Issue #5515: str.format() type 'n' combined with commas and leading
2109 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002110
2111- Implement PEP 378, Format Specifier for Thousands Separator, for
2112 floats.
2113
Mark Dickinson3370cce2009-04-17 22:40:53 +00002114- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002115 1e11, not 1e12. This avoids printing 13 significant digits in
2116 situations where only 12 of them are correct. Example problem
2117 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2118 long time.)
2119
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002120- Issue #1580: On most platforms, use a 'short' float repr: for a
2121 finite float x, repr(x) now outputs a string based on the shortest
2122 sequence of decimal digits that rounds to x. Previous behaviour was
2123 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002124 Another minor difference is that the new repr switches to
2125 exponential notation at 1e16 instead of the previous 1e17; this
2126 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002127
2128 There's a new sys attribute sys.float_repr_style, which takes
2129 the value 'short' to indicate that we're using short float repr,
2130 and 'legacy' if the short float repr isn't available for one
2131 reason or another.
2132
2133 The float repr change involves incorporating David Gay's 'perfect
2134 rounding' code into the Python core (it's in Python/dtoa.c). As a
2135 secondary consequence, all string-to-float and float-to-string
2136 conversions (including all float formatting operations) will be
2137 correctly rounded on these platforms.
2138
2139 See issue 1580 discussions for details of platforms for which
2140 this change does not apply.
2141
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002142- Issue #5759: float() didn't call __float__ on str subclasses.
2143
Georg Brandlabc38772009-04-12 15:51:51 +00002144- The string.maketrans() function is deprecated; there is a new static method
2145 maketrans() on the bytes and bytearray classes. This removes confusion about
2146 the types string.maketrans() is supposed to work with, and mirrors the
2147 methods available on the str class.
2148
R. David Murraydc6da8a2009-04-09 22:16:43 +00002149- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2150 its clarity and its speed.
2151
Matthias Klose091c7b12009-04-07 13:24:27 +00002152- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2153 to avoid compiler warnings.
2154
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002155- Issue #3739: The unicode-internal encoder now reports the number of characters

2304 insufficient checks in accessors of Exception.__context__.
2305
Guido van Rossum0ad59d42009-03-30 22:01:35 +00002306- Issue #5604: non-ASCII characters in module name passed to

2314
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002315- Issue #4688: Add a heuristic so that tuples and dicts containing only
2316 untrackable objects are not tracked by the garbage collector. This can
2317 reduce the size of collections and therefore the garbage collection overhead
2318 on long-running programs, depending on their particular use of datatypes.

2325 2**15 for the internal representation of integers, for performance
2326 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
2327 --enable-big-digits option to configure, which overrides the
2328 default. Add sys.int_info structseq to provide information about
2329 the internal format.
2330
Mark Dickinson081dfee2009-03-18 14:47:41 +00002331- Issue #4474: PyUnicode_FromWideChar now converts characters outside
2332 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
2333 and sizeof(Py_UNICODE) == 2.
2334
Eric Smith8ec90442009-03-14 12:29:34 +00002335- Issue #5237: Allow auto-numbered fields in str.format(). For

Mark Dickinson87ec0852009-02-09 17:15:59 +00002441- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2442 it now forces its argument to double before testing for infinity.
2443
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002444- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002453
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002454- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002455 were suppressing all exceptions. These include list() and bytearray().

Mark Dickinson1124e712009-01-28 21:25:58 +00002457- Issue #4707: round(x, n) now returns an integer if x is an integer.
2458 Previously it returned a float.
2459
Antoine Pitroub52ec782009-01-25 16:34:23 +00002460- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2461 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2462 evaluation loop is compiled with a new dispatch mechanism which gives
2463 speedups of up to 20%, depending on the system, on various benchmarks.
2464
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002465- Issue #4874: Most builtin decoders now reject unicode input.

2471
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002472- Issue #4838: When a module is deallocated, free the memory backing the
2473 optional module state data.
2474
Mark Dickinson8055afd2009-01-17 10:04:45 +00002475- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2476 type to (void *).
2477
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002478- Issue #4935: The overflow checking code in the expandtabs() method common
2479 to str, bytes and bytearray could be optimized away by the compiler, letting
2480 the interpreter segfault instead of raising an error.
2481
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002482- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2483 __next__ method.
2484
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002485- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2486 function no longer attempt to call the __long__ slot to convert an object
2487 to an integer. Only the __int__ and __trunc__ slots are examined.
2488
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002489- Issue #4893: Use NT threading on CE.
2490

2492
Antoine Pitrouab868312009-01-10 15:40:25 +00002493- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2494 common cases are optimized thanks to a dedicated fast path and a moderate
2495 amount of loop unrolling.
2496
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002497- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2498 collecting the oldest generation) so that allocating lots of objects without
2499 destroying them does not show quadratic performance. Based on a proposal by
2500 Martin von Löwis at
2501 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2502
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002503- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002504 having been closed (for instance, a read() call could return some
2505 previously buffered data). Patch by Dmitry Vasiliev.
2506
Antoine Pitrou05608432009-01-09 18:53:14 +00002507- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2508 flag to work properly. Furthermore, when specifying -u, the text stdout
2509 and stderr streams have line-by-line buffering enabled (the default being
2510 to buffer arbitrary chunks of data).
2511
Raymond Hettinger35631532009-01-09 03:58:09 +00002512- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2513 instead of ints (reducing its size from 4 to 8 times thereby reducing
2514 Python's overall memory).
2515
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002516- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2517 an existing .py counterpart, override the co_filename attributes of all
2518 code objects if the original filename is obsolete (which can happen if the
2519 file has been renamed, moved, or if it is accessed through different paths).
2520 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2521
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002522- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2523 one byte. Also fixes the meaning of len() so that it returns the number of
2524 items, rather than the size in bytes.
2525
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002526- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2527
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002528- Issue #4747: When the terminal does not use utf-8, executing a script with
2529 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2530
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002531- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002532 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002533
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002534- Issue #3680: Reference cycles created through a dict, set or deque iterator
2535 did not get collected.
2536
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002537- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2538 where the tp_hash and tp_dict slots are both NULL.
2539
Georg Brandlccc47b62008-12-28 11:44:14 +00002540- Issue #4759: None is now allowed as the first argument of
2541 bytearray.translate(). It was always allowed for bytes.translate().
2542
Skip Montanaro80072cb2008-12-23 03:51:14 +00002543- Added test case to ensure attempts to read from a file opened for writing
2544 fail.
2545
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002546- Issue #3106: Speedup some comparisons (str/str and int/int).

2550
Antoine Pitrou621601a2008-12-17 23:18:19 +00002551- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2552 print elapsed times, not only when some objects are uncollectable /
2553 unreachable. Original patch by Neil Schemenauer.
2554
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002555- Issue #3439: Add a bit_length method to int.
2556
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002557- Issue #2173: When getting device encoding, check that return value of
2558 nl_langinfo is not the empty string. This was causing silent build
2559 failures on OS X.
2560
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002561- Issue #4597: Fixed several opcodes that weren't always propagating
2562 exceptions.
2563
2564- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002565 context manager returns a value that cannot be converted to a bool.
2566
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002567- Issue #4445: Replace "sizeof(PyBytesObject)" with
2568 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2569 bytes instances. On a typical machine this saves 3 bytes of memory
2570 (on average) per allocation of a bytes instance.
2571
Christian Heimesa872de52008-12-05 08:26:55 +00002572- Issue #4533: File read operation was dreadfully slow due to a slowly
2573 growing read buffer. Fixed by using the same growth rate algorithm as
2574 Python 2.x.
2575
Antoine Pitrou5504e892008-12-06 21:27:53 +00002576- Issue #4509: Various issues surrounding resize of bytearray objects to
2577 which there are buffer exports (e.g. memoryview instances).
2578
Georg Brandlf9734072008-12-07 15:30:06 +00002579- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2580 method on file objects with closefd=False. The file descriptor is still
2581 kept open but the file object behaves like a closed file. The ``FileIO``
2582 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002584- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2592 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2593 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2594 of using the replace error handler in PyUnicode_DecodeUTF8().

Antoine Pitrou88909542009-06-29 13:54:42 +00003196- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
3197 regression tests in parallel, shortening the total runtime.

Guilherme Polo2a998fa2009-06-21 17:40:07 +00003199- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
3200 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
3201 the same behaviour as test_ttkguionly (and now also test_tk) which is to
3202 skip the tests if DISPLAY is defined but can't be used.

R. David Murraya21e4ca2009-03-31 23:16:50 +00003204- regrtest no longer treats ImportError as equivalent to SkipTest. Imports
Vinay Sajipad5fa2f2009-04-27 13:55:05 +00003205 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00003206 from test support, which does the conversion.

Guilherme Polo9de29af2009-01-28 20:40:48 +00003208- Issue #5083: New 'gui' resource for regrtest.
