13-----------------
14
Victor Stinner0fe25a42010-06-17 23:08:50 +000015- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000016 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
17 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000018
Mark Dickinsond35a32e2010-06-17 12:33:22 +000019- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
20 compilation code dealing with unary minus applied to a constant.
21 The removed code was mutating the ST, causing a second compilation
22 to fail.
23
Victor Stinner554f3f02010-06-16 23:33:54 +000024- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
25 mode raises unicode errors. The encoder only supports "strict" and "replace"
26 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000027 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000028
Victor Stinner06e49dd2010-06-13 18:21:50 +000029- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
30 formats if the string contains a null byte/character. Write unit tests for
31 string formats.
32
Nick Coghlan5e76e942010-06-12 13:42:46 +000033- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
34 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
35 location of the raised exception.
36
Victor Stinner313a1202010-06-11 23:56:51 +000037- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
38 filenames and enable os.fsencode().
39
Benjamin Peterson285a6892010-06-22 19:21:52 +000040- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
41
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000042- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
43 the interpreter with characters outside the Basic Multilingual Plane
44 (higher than 0x10000).
45
Mark Dickinsonc7301312010-06-10 16:05:10 +000046- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
47 raise TypeError instead of giving a DeprecationWarning when a float
48 is parsed using the 'L' code (for long long). (All other integer
49 codes already raise TypeError in this case.)
50
Victor Stinner600d3be2010-06-10 12:00:55 +000051- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
52 enable shortcuts for upper case encoding name. Add also a shortcut for
53 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
54
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000055- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
56 doesn't support "char buffer" anymore in Python3.
57
58- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
59 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
60 like bytearray.
61
Victor Stinner33109a12010-05-28 21:55:10 +000062- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
63 used anymore and it was never documented.
64
Benjamin Peterson95304522010-06-08 14:57:22 +000065- In the str.format(), raise a ValueError when indexes to arguments are too
66 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000067
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000068- Issue #2844: Make int('42', n) consistently raise ValueError for
69 invalid integers n (including n = -909).
70
Mark Dickinsondc787d22010-05-23 13:33:13 +000071- Issue #8188: Introduce a new scheme for computing hashes of numbers
72 (instances of int, float, complex, decimal.Decimal and
73 fractions.Fraction) that makes it easy to maintain the invariant
74 that hash(x) == hash(y) whenever x and y have equal value.
75
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000076- Issue #8748: Fix two issues with comparisons between complex and integer
77 objects. (1) The comparison could incorrectly return True in some cases
78 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
79 (2) The comparison raised an OverflowError for large integers, leading
80 to unpredictable exceptions when combining integers and complex objects
81 in sets or dicts.
82
Victor Stinner7d79b8b2010-05-19 20:40:50 +000083- Issue #8766: Initialize _warnings module before importing the first module.
84 Fix a crash if an empty directory called "encodings" exists in sys.path.
85
Victor Stinner9ca9c252010-05-19 16:53:30 +000086- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
87 encoding and surrogateespace error handler instead of the locale encoding to
88 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
89
Victor Stinner372ac5e2010-05-17 01:26:01 +000090- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
91 (instead of strict) error handler to escape surrogates
92
Victor Stinnerae6265f2010-05-15 16:27:27 +000093- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
94 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000095 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
96 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000097
Victor Stinner59e62db2010-05-15 13:14:32 +000098- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
99 error handler, not only the default error handler (strict)
100
Victor Stinnerb744ba12010-05-15 12:27:16 +0000101- Issue #8610: Load file system codec at startup, and display a fatal error on
102 failure. Set the file system encoding to utf-8 (instead of None) if getting
103 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
104
Victor Stinner0964ee12010-04-30 16:48:45 +0000105- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
106 PyUnicode_FromString() to support surrogates in the filename and use the
107 right encoding
108
Georg Brandl8569e582010-05-19 20:57:08 +0000109- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
110
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000111- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
112
Benjamin Petersonfb886362010-04-24 18:21:17 +0000113- Issue #8419: Prevent the dict constructor from accepting non-string keyword
114 arguments.
115
Victor Stinner14284c22010-04-23 12:02:30 +0000116- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
117 indirectly Python signal handlers anymore because mywrite() ignores
118 exceptions (KeyboardInterrupt)
119
Victor Stinner31be90b2010-04-22 19:38:16 +0000120- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
121 unicode string (eg. backslashreplace)
122
Victor Stinnerdcb24032010-04-22 12:08:36 +0000123- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
124 you have to convert your bytearray filenames to bytes
125
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000126- Issue #7332: Remove the 16KB stack-based buffer in
127 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
128 benefit compared to the dynamic memory allocation fallback. Patch by
129 Charles-François Natali.
130
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000131- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
132 passed to bytes or bytearray.
133
Philip Jenvey0805ca32010-04-07 04:04:10 +0000134- Issue #7301: Add environment variable $PYTHONWARNINGS.
135
Benjamin Petersond856ab62010-04-06 21:55:16 +0000136- Issue #8329: Don't return the same lists from select.select when no fds are
137 changed.
138
Mark Dickinson3318d292010-04-06 16:53:17 +0000139- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
140 on 64-bit machines. The shift count for either left or right shift is
141 permitted to be up to sys.maxsize.
142
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000143- Ensure that tokenization of identifiers is not affected by locale.

150 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000151
Victor Stinner120c2122010-03-25 00:30:28 +0000152- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
153 is unknown
154

156
Mark Dickinsond59b4162010-03-13 11:34:40 +0000157- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
158 PyMemberDefs could produce an internal error; raise TypeError instead.
159
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000160- Issue #7845: Rich comparison methods on the complex type now return
161 NotImplemented rather than raising a TypeError when comparing with an
162 incompatible type; this allows user-defined classes to implement their own
163 comparisons with complex.
164
Victor Stinner52f6dd72010-03-12 14:45:56 +0000165- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
166 (SIGINT). If an error occurs while importing the site module, the error is
167 printed and Python exits. Initialize the GIL before importing the site
168 module.
169
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000170- Issue #7173: Generator finalization could invalidate sys.exc_info().

173 a fatal error in low memory condition.
174
Victor Stinner6aa278e2010-03-03 00:18:49 +0000175- Issue #7820: The parser tokenizer restores all bytes in the right if
176 the BOM check fails.
177
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000178- Handle errors from looking up __prepare__ correctly.
179
Larry Hastings1373a072010-02-24 22:49:58 +0000180- Issue #5939: Add additional runtime checking to ensure a valid capsule
181 in Modules/_ctypes/callproc.c.
182
Eric Smith0facd772010-02-24 15:42:29 +0000183- Issue #7309: Fix unchecked attribute access when converting
184 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
185 strings.

194 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
195 and PyOS_string_to_double instead. See issue #5835 for the original
196 deprecations.
197
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000198- Issue #7385: Fix a crash in `MemoryView_FromObject` when
199 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
200
Mark Dickinsonbc099642010-01-29 17:27:24 +0000201- Issue #7788: Fix an interpreter crash produced by deleting a list
202 slice with very large step value.
203
Eric Smithf7bb5782010-01-27 00:44:57 +0000204- Issue #7766: Change sys.getwindowsversion() return value to a named
205 tuple and add the additional members returned in an OSVERSIONINFOEX
206 structure. The new members are service_pack_major, service_pack_minor,
207 suite_mask, and product_type.
208
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000209- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
210 could crash in many places because of the PyByteArray_AS_STRING() macro
211 returning NULL. The macro now returns a statically allocated empty
212 string instead.
213
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000214- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
215 where the right hand operand is a set of constants, by turning the set into
216 a frozenset and pre-building it as a constant. The comparison operation
217 is made against the constant instead of building a new set each time it is
218 executed (a similar optimization already existed which turned a list of
219 constants into a pre-built tuple). Patch and additional tests by Dave
220 Malcolm.
221
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000222- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
223 methods of bytes, bytearray and unicode objects by using a common
224 implementation based on stringlib's fast search. Patch by Florent Xicluna.

227 alpha 2, including: (1) a serious 'wrong output' bug that could
228 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
229 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000230 strings corresponding to subnormal values, (3) a memory leak for
231 some values large enough to cause overflow, and (4) a number of
232 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000233
Benjamin Petersonaea44282010-01-04 01:10:28 +0000234- The __complex__ method is now looked up on the class of instances to make it
235 consistent with other special methods.

238 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
239
Benjamin Petersond12362a2009-12-30 19:44:54 +0000240- Issue #7604: Deleting an unset slotted attribute did not raise an
241 AttributeError.

244 negative zero) in ** operator. The behaviour now conforms to that
245 described in C99 Annex F.
246
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000247- Issue #1811: improve accuracy and cross-platform consistency for
248 true division of integers: the result of a/b is now correctly
249 rounded for ints a and b (at least on IEEE 754 platforms), and in
250 particular does not depend on the internal representation of an int.
251
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000252- Issue #6834: replace the implementation for the 'python' and 'pythonw'
253 executables on OSX.
254
255 These executables now work properly with the arch(1) command:
256 ``arch -ppc python`` will start a universal binary version of python
257 in PPC mode (unlike previous releases).
258
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000259- Issue #7466: segmentation fault when the garbage collector is called
260 in the middle of populating a tuple. Patch by Florent Xicluna.

274 implement the relevant rich comparison methods.
275
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000276- Issue #7298: fixes for range and reversed(range(...)). Iteration
277 over range(a, b, c) incorrectly gave an empty iterator when a, b and
278 c fit in C long but the length of the range did not. Also fix
279 several cases where reversed(range(a, b, c)) gave wrong results, and
280 fix a refleak for reversed(range(a, b, c)) with large arguments.
281
Raymond Hettingerfc438512009-11-01 20:55:33 +0000282- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitrouf978fac2010-05-21 17:25:34 +0000392- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
393 embedders of the interpreter to set sys.argv without also modifying
394 sys.path. This helps fix `CVE-2008-5983
395 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
396
Benjamin Petersonfb886362010-04-24 18:21:17 +0000397- Add PyArg_ValidateKeywordArguments, which checks if all keyword arguments are

414 code. This will become a TypeError in a future version of Python,
415 to match the behaviour of the other integer format codes.

426 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
427 should used for accessing the d_type and d_name members of structures
428 using PyDescr_COMMON.

468
Mark Dickinson9b88b912010-06-11 10:46:57 +0000469- Issue #8188: Comparisons between Decimal and Fraction objects are
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000470 now permitted, returning a result based on the exact numerical
471 values of the operands. This builds on issue #2531, which allowed
472 Decimal-to-float comparisons; all comparisons involving numeric
473 types (bool, int, float, complex, Decimal, Fraction) should now
474 act as expected.

Mark Dickinsonc69160e2010-05-04 14:35:33 +0000607- Issue #8567: Fix precedence of signals in Decimal module: when a
608 Decimal operation raises multiple signals and more than one of those
609 signals is trapped, the specification determines the order in which
610 the signals should be handled. In many cases this order wasn't
611 being followed, leading to the wrong Python exception being raised.
612
Antoine Pitrou6be88762010-05-03 16:48:20 +0000613- Issue #7865: The close() method of :mod:`io` objects should not swallow
614 exceptions raised by the implicit flush(). Also ensure that calling
615 close() several times is supported. Patch by Pascal Chambon.
616
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000617- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
618 gc.DEBUG_STATS.
619
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000620- Issue #8354: The siginterrupt setting is now preserved for all signals,
621 not just SIGCHLD.
622
Georg Brandl25106ce2010-05-21 21:49:47 +0000623- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000624 webbrowser.get("safari").
625
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000626- Issue #8464: tarfile no longer creates files with execute permissions set
627 when mode="w|" is used.
628
Antoine Pitroubf043492010-04-29 10:11:46 +0000629- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
630 of the Linux kernel. Patch by Yaniv Aknin.
631
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000632- Issue #8295: Added shutil.unpack_archive.
633
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000634- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
635 It should correctly return an empty response now.
636
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000637- Issue #8546: Reject None given as the buffering argument to _pyio.open.
638
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000639- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
640 Sridhar Ratnakumar.
641
R. David Murrayad78d152010-04-27 02:45:53 +0000642- Issue #6656: fix locale.format_string to handle escaped percents
643 and mappings.
644
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000645- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
646 where the method could block indefinitely if called just before the
647 event loop started running. This also fixes the occasional freezes
648 witnessed in test_httpservers.
649
Antoine Pitrou40f08742010-04-24 22:04:40 +0000650- Issue #8524: When creating an SSL socket, the timeout value of the
651 original socket wasn't retained (instead, a socket with a positive timeout
652 would be turned into a non-blocking SSL socket).
653
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000654- Issue #5103: SSL handshake would ignore the socket timeout and block
655 indefinitely if the other end didn't respond.
656
657- The do_handshake() method of SSL objects now adjusts the blocking mode of
658 the SSL structure if necessary (as other methods already do).
659
Victor Stinner13bb71c2010-04-23 21:41:56 +0000660- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
661 and bytes strings for environment keys and values
662
Victor Stinner4d078042010-04-23 19:28:32 +0000663- Issue #8467: Pure Python implementation of subprocess encodes the error
664 message using surrogatepass error handler to support surrogates in the
665 message
666

668
Sean Reifscheider13daf122010-04-23 09:29:52 +0000669- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
670 the string "python" as the *ident*. openlog() arguments are all optional
671 and keywords.
672
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000673- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
674 a non-infinite timeout. Also make that method friendlier with applications
675 wanting to continue using the socket in clear-text mode, by disabling
676 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
677
Antoine Pitrou7062db82010-04-22 13:30:10 +0000678- Issue #8496: make mailcap.lookup() always return a list, rather than an
679 iterator. Patch by Gregory Nofi.
680
Victor Stinner35466c52010-04-22 11:23:23 +0000681- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
682 collation name contains a surrogate character.
683
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000684- Issue #8484: Load all ciphers and digest algorithms when initializing
685 the _ssl extension, such that verification of some SSL certificates
686 doesn't fail because of an "unknown algorithm".
687
Tarek Ziadéfb437512010-04-20 08:57:33 +0000688- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
689
Victor Stinnere125f132010-05-15 21:04:43 +0000690- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000691 shutil.copytree.
692
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000693- Issue #4814: timeout parameter is now applied also for connections resulting
694 from PORT/EPRT commands.
695
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000696- Issue #8463: added missing reference to bztar in shutil's documentation.
697
Ronald Oussoren84151202010-04-18 20:46:11 +0000698- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
699 (as long as the user didn't specify 'automatic proxy configuration').
700
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000701- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
702 code as stated in RFC-959 at chapter 5.4.
703
Victor Stinner738446f02010-04-18 00:00:44 +0000704- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
705 surrogates.
706
Antoine Pitrou0454af92010-04-17 23:51:58 +0000707- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000708 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000709
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000710- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
711 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
712
Victor Stinner0e59cc32010-04-16 23:49:32 +0000713- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
714 the current working directory.
715
Victor Stinner5bfe1462010-04-16 13:28:05 +0000716- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
717 using backslashreplace error handler

723 Locke and Hans Ulrich Niedermann.
724
R. David Murrayd48739f2010-04-14 18:59:18 +0000725- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
726
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000727- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
728 module now takes an optional timeout argument in seconds. Timeout support
729 relies on the system threading library, so as to avoid a semi-busy wait
730 loop.
731
Victor Stinner485fb562010-04-13 11:07:24 +0000732- Issue #8383: pickle and pickletools use surrogatepass error handler when
733 encoding unicode as utf8 to support lone surrogates and stay compatible with
734 Python 2.x and 3.0
735
R. David Murrayb2416e52010-04-12 16:58:02 +0000736- Issue #7585: difflib context and unified diffs now place a tab between
737 filename and date, conforming to the 'standards' they were originally
738 designed to follow. This improves compatibility with patch tools.
739
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000740- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
741 character sets will now consistently use a Content-Transfer-Encoding of
742 7bit rather than sometimes being marked as 8bit.
743
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000744- Issue #8375: test_distutils now checks if the temporary directory are still
745 present before it cleans them.
746
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000747- Issue #8374: Update the internal alias table in the :mod:`locale` module
748 to cover recent locale changes and additions.
749
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000750- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
751 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
752 and `ssl.OPENSSL_VERSION_NUMBER`.
753
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000754- Add functools.total_ordering() and functools.cmp_to_key().
755
Mark Dickinson089b00c2010-04-03 15:51:03 +0000756- Issue #8257: The Decimal construct now accepts a float instance
757 directly, converting that float to a Decimal of equal value:
758
759 >>> Decimal(1.1)
760 Decimal('1.100000000000000088817841970012523233890533447265625')
761
Mark Dickinson98127c32010-04-03 11:18:52 +0000762- Issue #8294: The Fraction constructor now accepts Decimal and float
763 instances directly.
764
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000765- Issue #7279: Comparisons involving a Decimal signaling NaN now
766 signal InvalidOperation instead of returning False. (Comparisons
767 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
768 are now hashable; Decimal signaling NaNs remain unhashable.
769
770- Issue #2531: Comparison operations between floats and Decimal
771 instances now return a result based on the numeric values of the
772 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000773 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000774 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000775
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000776- Added a subtract() method to collections.Counter().
777
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000778- Issue #8233: When run as a script, py_compile.py optionally takes a single
779 argument `-` which tells it to read files to compile from stdin. Each line
780 is read on demand and the named file is compiled immediately. (Original
781 patch by Piotr Ożarowski).
782
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000783- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
784 form feed (0x0C) are now considered linebreaks, as specified in Unicode
785 Standard Annex #14. See issue #7643.
786 http://www.unicode.org/reports/tr14/
787
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000788- Comparisons using one of <, <=, >, >= between a complex instance and
789 a Fractions instance now raise TypeError instead of returning
790 True/False. This makes Fraction <=> complex comparisons consistent with
791 int <=> complex, float <=> complex, and complex <=> complex comparisons.
792
Antoine Pitrou39b35432010-03-23 00:25:54 +0000793- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
794 some methods (such as oss_mixer_device.fileno()) were not available.
795 Initial patch by Bertrand Janin.
796
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000797- Issue #8205: Remove the "Modules" directory from sys.path when Python is
798 running from the build directory (POSIX only).
799
Antoine Pitrou910bd512010-03-22 20:11:09 +0000800- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
801 didn't support chflags() (for example ZFS under FreeBSD). The error is
802 now silenced.
803
R. David Murrayca2edce2010-03-22 17:48:48 +0000804- Issue #7860: platform.uname now reports the correct 'machine' type
805 when Python is running in WOW64 mode on 64 bit Windows.
806
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000807- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
808 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
809 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000810
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000811- Issue #4282: Fix the main function of the profile module for a non-ASCII
812 script, open the file in binary mode and not in text mode with the default
813 (utf8) encoding.
814
Florent Xicluna54467e02010-03-21 12:29:50 +0000815- Issue #8179: Fix macpath.realpath() on a non-existing path.
816
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000817- Issue #8024: Update the Unicode database to 5.2.
818
Benjamin Peterson00888932010-03-18 22:37:38 +0000819- Issue #8168: py_compile now handles files with utf-8 BOMS.
820
Benjamin Peterson689a5582010-03-18 22:29:52 +0000821- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
822 detected.
823
Martin v. Löwis4b003072010-03-16 13:19:21 +0000824- Issue #6716/2: Backslash-replace error output in compilall.
825
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000826- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
827 with Tcl/Tk-8.5.
828
Matthias Klosec33b9022010-03-16 00:36:26 +0000829- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000831- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
832 the locale.
833
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000834- The internals of the subprocess module on POSIX systems have been replaced
835 by an extension module (_posixsubprocess) so that the fork()+exec() can be
836 done safely without the possibility of deadlock in multithreaded applications.
837
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000838- subprocess.Popen now has restore_signals and start_new_session features.
839 The default of restore_signals=True is a new behavior compared to earlier
840 Python versions. This means that signals such as SIGPIPE are not ignored
841 by default in subprocesses launched by Python (Issue #1652).
842
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000843- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
844 cElementTree module is updated too.
845
Victor Stinnerb33062c2010-03-12 14:27:16 +0000846- Issue #7774: Set sys.executable to an empty string if argv[0] has been set to

854
Gerhard Häringf9cee222010-03-05 15:20:03 +0000855- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure

903 exception of canonical and is_canonical) now accept instances of int
904 and long wherever a Decimal instance is accepted, and implicitly
905 convert that argument to Decimal. Previously only some arguments
906 were converted.

910
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000911- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
912 in XML processing instructions and comments. These raw characters are
913 allowed by the XML specification, and are necessary when outputting e.g.
914 PHP code in a processing instruction. Patch by Neil Muller.

922
Antoine Pitroub6375f12010-02-04 20:23:24 +0000923- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is

926 type is specified. Patch by Brian Curtin.
927
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000928- Issue #6939: Fix file I/O objects in the `io` module to keep the original
929 file position when calling `truncate()`. It would previously change the
930 file position to the given argument, which goes against the tradition of
931 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
932
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000933- Issue #7610: Reworked implementation of the internal
934 :class:`zipfile.ZipExtFile` class used to represent files stored inside
935 an archive. The new implementation is significantly faster and can
936 be wrapped in a :class:`io.BufferedReader` object for more speedups.
937 It also solves an issue where interleaved calls to `read()` and
938 `readline()` give wrong results. Patch by Nir Aides.
939

1021 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1022 the same as passing no argument.

1102 to execute file paths that refer to source or compiled Python files as well
1103 as zipfiles, directories and other valid sys.path entries that contain a
1104 __main__.py file. This allows applications that run other Python scripts to
1105 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001124 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001125 recursive locks as fast as regular non-recursive locks (previously,
1126 they were slower by 10x to 15x).

1146 reading from stdin so that existing input does not confuse it and
1147 lead to incorrect entry or an IOError. It also properly flushes it
1148 afterwards to avoid the terminal echoing the input afterwards on
1149 OSes such as Solaris.

Brett Cannon69194272009-07-20 04:23:48 +00001281- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
1282 loaders that allow for modules to be executed. Both importlib.abc.PyLoader
1283 and PyPycLoader inherit from this class and provide implementations in
1284 relation to other methods required by the ABCs.
1285
Brett Cannon64ef00f2009-07-20 03:19:18 +00001286- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
1287 the documentation said it did even though the code in PyLoader relied on the
1288 abstract method required by ResourceLoader.

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001335- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1336 10,000. Prior to this change, timezone adjustment in utctimetuple()
1337 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1338 raised in these edge cases.
1339
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001340- Issue #6641: The ``datetime.strptime`` method now supports the
1341 ``%z`` directive. When the ``%z`` directive is present in the
1342 format string, an aware ``datetime`` object is returned with
1343 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1344 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1345 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1346 without ``%z`` is discarded.
1347
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001348- Issue #5094: The ``datetime`` module now has a simple concrete class
1349 implementing ``datetime.tzinfo`` interface. Instances of the new
1350 class, ``datetime.timezone``, return fixed name and UTC offset from
1351 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1352 method always returns ``None``. A class attribute, ``utc`` contains
1353 an instance representing the UTC timezone. Original patch by Rafe
1354 Kaplan.
1355
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001356- Issue #8973: Add __all__ to struct module; this ensures that

1358
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001359- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001360 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001361 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00001362
Stefan Kraha3ac44e2010-06-08 14:00:52 +00001363- Issue #7384: If the system readline library is linked against ncurses,
1364 the curses module must be linked against ncurses as well. Otherwise it
1365 is not safe to load both the readline and curses modules in an application.
1366
Brian Curtin60853212010-05-26 17:43:50 +00001367- Issue #2810: Fix cases where the Windows registry API returns

1369
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001370- Issue #8692: Optimize math.factorial: replace the previous naive
1371 algorithm with an improved 'binary-split' algorithm that uses fewer
1372 multiplications and allows many of the multiplications to be
1373 performed using plain C integer arithmetic instead of PyLong
1374 arithmetic. Also uses a lookup table for small arguments.
1375
Mark Dickinson85eacea2010-05-10 16:27:45 +00001376- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1377 overflow checks in the audioop module.
1378
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001379- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1380 calculating with integer arithmetic instead of float arithmetic internally):
1381 the result is now always correctly rounded, and is equivalent to td /
1382 timedelta(seconds=1).
1383
Mark Dickinson7c186e22010-04-20 22:32:49 +00001384- Issue #2706: Allow division of a timedelta by another timedelta:

1386 and divmod(timedelta, timedelta) are all supported.
1387
Victor Stinnerfebecd82010-04-16 12:07:30 +00001388- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
1389
Mark Dickinsonc5935772010-04-03 15:54:36 +00001390- Issue #8300: When passing a non-integer argument to struct.pack with any
1391 integer format code, struct.pack first attempts to convert the non-integer
1392 using its __index__ method. If that method is non-existent or raises
1393 TypeError it goes on to try the __int__ method, as described below.
1394
Matthias Klosea8349752010-03-15 13:25:28 +00001395- Issue #8142: Update libffi to the 3.0.9 release.

1617 user running the tests.

1644 leak-chasing test runs give sensible results. The previous method of
1645 reaping threads could return successfully while some Thread objects were
1646 still referenced. This also introduces a new private function:
1647 :func:`_thread._count()`.
1648
R. David Murray27144602009-10-19 15:26:16 +00001649- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1650 longer runs the risk of causing the worker thread to fail.
1651
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001652- Issue #7055: test___all__ now greedily detects all modules which have an
1653 __all__ attribute, rather than using a hardcoded and incomplete list.

1657 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001658
Mark Dickinson2e304402009-10-04 18:43:54 +00001659- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1660
Brett Cannon3c273842009-07-20 00:14:29 +00001661- Fixed tests in importlib.test.source.test_abc_loader that were masking
1662 the proper exceptions that should be raised for missing or improper code

1752 are always None now.
1753
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00001754- Issue #6137: The pickle module now translates module names when loading
1755 or dumping pickles with a 2.x-compatible protocol, in order to make data
1756 sharing and migration easier. This behaviour can be disabled using the
1757 new `fix_imports` optional argument.

1804-----------------
1805
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001806- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1807 of the command line.
1808
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001809- Issue #6012: Add cleanup support to O& argument parsing.
1810
Eric Smith41669ca2009-05-23 14:23:22 +00001811- Issue #6089: Fixed str.format with certain invalid field specifiers
1812 that would raise SystemError.
1813
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001814- Issue #5982: staticmethod and classmethod now expose the wrapped
1815 function with __func__.
1816
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001817- Added support for multiple context managers in the same with-statement.
1818 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001819
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001820- Issue #5829: complex("1e500") no longer raises OverflowError. This
1821 makes it consistent with float("1e500") and interpretation of real
1822 and imaginary literals.
1823
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001824- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1825
R. David Murraydd226ea2009-05-13 12:27:21 +00001826- Issue #5994: the marshal module now has docstrings.
1827
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001828- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1829 (1) inf and nan strings with trailing whitespace were incorrectly
1830 rejected; (2) parsing of strings representing infinities and nans
1831 was locale aware; and (3) the interpretation of fromhex('-nan')
1832 didn't match that of float('-nan').
1833
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001834Library
1835-------
1836
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001837- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1838
R. David Murrayfb123912009-05-28 18:19:00 +00001839- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1840
R. David Murray1f1b9d32009-05-27 20:56:59 +00001841- Issue #6121: pydoc now ignores leading and trailing spaces in the
1842 argument to the 'help' function.
1843
Georg Brandlfaf41492009-05-26 18:31:11 +00001844- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1845 arguments for strings with a space in them.
1846
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001847- collections.namedtuple() was not working with the following field
1848 names: cls, self, tuple, itemgetter, and property.
1849
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001850- In unittest, using a skipping decorator on a class is now equivalent to
1851 skipping every test on the class. The ClassTestSuite class has been removed.
1852
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001853- Issue #6050: Don't fail extracting a directory from a zipfile if
1854 the directory already exists.
1855
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001856- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1857 than an int, which makes some operations possible under 64-bit Linux (e.g.
1858 DN_MULTISHOT with F_NOTIFY).
1859
Antoine Pitrou716c4442009-05-23 19:04:03 +00001860- Issue #5761: Add the name of the underlying file to the repr() of various
1861 IO objects.
1862
R. David Murraycaa27b72009-05-23 18:49:56 +00001863- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1864 by Musashi Tamura, tests by Marcin Bachry.
1865
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001866- Issue #1983: Fix functions taking or returning a process identifier to use
1867 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1868 a process identifier type wider than the standard C integer type.
1869
R. David Murray87e20742009-05-23 01:30:26 +00001870- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1874 deepcopy()ing.
1875

Antoine Pitrou2ca24f02009-05-14 21:30:46 +00001880- Issue #1664: Make nntplib IPv6-capable. Patch by Derek Morr.
1881
Antoine Pitroue4501852009-05-14 18:55:55 +00001882- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1883 library. This means, for example, that opening an UTF-16 text file in
1884 append mode doesn't add a BOM at the end of the file if the file isn't
1885 empty.
1886
R. David Murray74b89242009-05-13 17:33:03 +00001887- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1888 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1889 corrects a pydoc regression.
1890
R. David Murray99352742009-05-07 18:24:38 +00001891- Issue 5955: aifc's close method did not close the file it wrapped,
1892 now it does. This also means getfp method now returns the real fp.
1893
Benjamin Peterson932073a2009-05-23 16:14:33 +00001894Installation
1895------------
1896
1897- Issue #6047: fullinstall has been removed because Python 3's executable will
1898 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001899
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001900- Lib/smtpd.py is no longer installed as a script.

Martin v. Löwisdb1c3992009-05-23 10:38:26 +00001909- Issue #6093: Fix off-by-one error in locale.strxfrm.
1910
Benjamin Peterson744af442009-05-23 18:51:49 +00001911- The _functools and _locale modules are now built into the libpython shared
1912 library instead of as extension modules.
Benjamin Peterson3dc22e82009-05-23 17:09:43 +00001913
Antoine Pitrou20327222009-05-24 20:39:11 +00001914Build
1915-----
1916
1917- Issue #3585: Add pkg-config support. It creates a python-2.7.pc file
1918 and a python3.pc symlink in the $(LIBDIR)/pkgconfig directory. Patch by
1919 Clinton Roy.
1920
Brett Cannon1262e7c2009-05-11 01:47:11 +00001921Tests
1922-----
1923
1924- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1925 tests on darwin even when the OS was installed on a case-sensitive
1926 filesystem. Also fixed tests that should not be run when
1927 sys.dont_write_bytecode is true.
1928
1929
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001930What's New in Python 3.1 beta 1?
1931================================
1932
Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001933*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001934
1935Core and Builtins
1936-----------------
1937
Mark Dickinson865e01a2009-05-07 16:37:01 +00001938- Issue #5914: Add new C API function PyOS_string_to_double, and
1939 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1940
Eric Smith741191f2009-05-06 13:08:15 +00001941- Issue #3382: float.__format__, complex.__format__, and %-formatting
1942 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1943 affects nan -> NAN and inf -> INF.
1944
Mark Hammond5a607a32009-05-06 08:04:54 +00001945- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1946 in all operations, including splitdrive, split, etc. splitunc() now issues
1947 a PendingDeprecation warning.
1948
Eric Smith63376222009-05-05 14:04:18 +00001949- Issue #5920: For float.__format__, change the behavior with the
1950 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1951 to be like 'g' but with at least one decimal point and with a
1952 default precision of 12. Previously, the behavior the same but with
1953 a default precision of 6. This more closely matches str(), and
1954 reduces surprises when adding alignment flags to the empty
1955 presentation type. This also affects the new complex.__format__ in
1956 the same way.
1957
Martin v. Löwis011e8422009-05-05 04:43:17 +00001958- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1959
R. David Murrayb18500d2009-05-04 22:59:07 +00001960- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1961 shadowed by classtype's, even if it was None. property now
1962 inserts the __doc__ into the subclass instance __dict__.
1963
Antoine Pitrou244651a2009-05-04 18:56:13 +00001964- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1965 sequences. Patch by Nick Barnes and Victor Stinner.
1966
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001967- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001968
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001969- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1970 received a new method, detach(). detach() disconnects the underlying stream
1971 from the buffer or text IO and returns it.
1972
Mark Dickinson33841c32009-05-01 15:37:04 +00001973- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1974 floats with absolute value over 1e50. Also remove length
1975 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1976 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001977
Eric Smith741191f2009-05-06 13:08:15 +00001978- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001979 format(complex(1, 2./3), '.5') now produces a sensible result.
1980
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001981- Issue #5864: Fix empty format code formatting for floats so that it
1982 never gives more than the requested number of significant digits.
1983
Eric Smith6dc46f52009-04-27 20:39:49 +00001984- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1985 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1986
Eric Smithcc32a112009-04-26 21:35:14 +00001987- Issue #5835: Deprecate PyOS_ascii_formatd.
1988
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001989- Issue #4971: Fix titlecase for characters that are their own
1990 titlecase, but not their own uppercase.
1991
Benjamin Peterson193152c2009-04-25 01:08:45 +00001992- Issue #5283: Setting __class__ in __del__ caused a segfault.
1993
Mark Dickinsonad476da2009-04-23 19:14:16 +00001994- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1995 z involves nans, infs or negative zeros.
1996
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001997- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001998
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001999- Issue #1869 (and many duplicates): make round(x, n) correctly
2000 rounded for a float x, by using the decimal <-> binary conversions
2001 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2002 consistently agrees with format(x, '.2f').
2003
Benjamin Petersonae937c02009-04-18 20:54:08 +00002004- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2005 some builtin types.
2006
Eric Smith0923d1d2009-04-16 20:16:10 +00002007- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2008
Eric Smith35e84722009-04-16 20:21:28 +00002009- Issue #5515: str.format() type 'n' combined with commas and leading
2010 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002011
2012- Implement PEP 378, Format Specifier for Thousands Separator, for
2013 floats.
2014
Mark Dickinson3370cce2009-04-17 22:40:53 +00002015- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002016 1e11, not 1e12. This avoids printing 13 significant digits in
2017 situations where only 12 of them are correct. Example problem
2018 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2019 long time.)
2020
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002021- Issue #1580: On most platforms, use a 'short' float repr: for a
2022 finite float x, repr(x) now outputs a string based on the shortest
2023 sequence of decimal digits that rounds to x. Previous behaviour was
2024 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002025 Another minor difference is that the new repr switches to
2026 exponential notation at 1e16 instead of the previous 1e17; this
2027 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002028
2029 There's a new sys attribute sys.float_repr_style, which takes
2030 the value 'short' to indicate that we're using short float repr,
2031 and 'legacy' if the short float repr isn't available for one
2032 reason or another.
2033
2034 The float repr change involves incorporating David Gay's 'perfect
2035 rounding' code into the Python core (it's in Python/dtoa.c). As a
2036 secondary consequence, all string-to-float and float-to-string
2037 conversions (including all float formatting operations) will be
2038 correctly rounded on these platforms.
2039
2040 See issue 1580 discussions for details of platforms for which
2041 this change does not apply.
2042
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002043- Issue #5759: float() didn't call __float__ on str subclasses.
2044
Georg Brandlabc38772009-04-12 15:51:51 +00002045- The string.maketrans() function is deprecated; there is a new static method
2046 maketrans() on the bytes and bytearray classes. This removes confusion about
2047 the types string.maketrans() is supposed to work with, and mirrors the
2048 methods available on the str class.

Mark Dickinsonc008a172009-02-01 13:59:22 +00002350- Issue #1717: Removed builtin cmp() function, dropped tp_compare
2351 slot, the C API functions PyObject_Compare and PyUnicode_Compare and
Mark Dickinsone94c6792009-02-02 20:36:42 +00002352 the type definition cmpfunc. The tp_compare slot has been renamed
2353 to tp_reserved, and is reserved for future usage.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002355- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002356 were suppressing all exceptions. These include list() and bytearray().
2357
Mark Dickinson1124e712009-01-28 21:25:58 +00002358- Issue #4707: round(x, n) now returns an integer if x is an integer.
2359 Previously it returned a float.
2360
Antoine Pitroub52ec782009-01-25 16:34:23 +00002361- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2362 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2363 evaluation loop is compiled with a new dispatch mechanism which gives
2364 speedups of up to 20%, depending on the system, on various benchmarks.
2365
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002366- Issue #4874: Most builtin decoders now reject unicode input.

Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002373- Issue #4838: When a module is deallocated, free the memory backing the
2374 optional module state data.
2375
Mark Dickinson8055afd2009-01-17 10:04:45 +00002376- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2377 type to (void *).
2378
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002379- Issue #4935: The overflow checking code in the expandtabs() method common
2380 to str, bytes and bytearray could be optimized away by the compiler, letting
2381 the interpreter segfault instead of raising an error.
2382
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002383- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2384 __next__ method.
2385
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002386- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2387 function no longer attempt to call the __long__ slot to convert an object
2388 to an integer. Only the __int__ and __trunc__ slots are examined.

2393
Antoine Pitrouab868312009-01-10 15:40:25 +00002394- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2395 common cases are optimized thanks to a dedicated fast path and a moderate
2396 amount of loop unrolling.
2397
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002398- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2399 collecting the oldest generation) so that allocating lots of objects without
2400 destroying them does not show quadratic performance. Based on a proposal by
2401 Martin von Löwis at
2402 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2403
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002404- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002405 having been closed (for instance, a read() call could return some
2406 previously buffered data). Patch by Dmitry Vasiliev.
2407
Antoine Pitrou05608432009-01-09 18:53:14 +00002408- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2409 flag to work properly. Furthermore, when specifying -u, the text stdout
2410 and stderr streams have line-by-line buffering enabled (the default being
2411 to buffer arbitrary chunks of data).
2412
Raymond Hettinger35631532009-01-09 03:58:09 +00002413- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2414 instead of ints (reducing its size from 4 to 8 times thereby reducing
2415 Python's overall memory).
2416
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002417- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2418 an existing .py counterpart, override the co_filename attributes of all
2419 code objects if the original filename is obsolete (which can happen if the
2420 file has been renamed, moved, or if it is accessed through different paths).
2421 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2422
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002423- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2424 one byte. Also fixes the meaning of len() so that it returns the number of
2425 items, rather than the size in bytes.
2426
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002427- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2428
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002429- Issue #4747: When the terminal does not use utf-8, executing a script with
2430 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2431
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002432- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

2436 did not get collected.
2437
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002438- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2439 where the tp_hash and tp_dict slots are both NULL.
2440
Georg Brandlccc47b62008-12-28 11:44:14 +00002441- Issue #4759: None is now allowed as the first argument of
2442 bytearray.translate(). It was always allowed for bytes.translate().
2443
Skip Montanaro80072cb2008-12-23 03:51:14 +00002444- Added test case to ensure attempts to read from a file opened for writing
2445 fail.

2451
Antoine Pitrou621601a2008-12-17 23:18:19 +00002452- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2457
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002458- Issue #2173: When getting device encoding, check that return value of
2459 nl_langinfo is not the empty string. This was causing silent build
2460 failures on OS X.
2461
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002462- Issue #4597: Fixed several opcodes that weren't always propagating
2463 exceptions.
2464
2465- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002466 context manager returns a value that cannot be converted to a bool.
2467
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002468- Issue #4445: Replace "sizeof(PyBytesObject)" with
2469 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2470 bytes instances. On a typical machine this saves 3 bytes of memory
2471 (on average) per allocation of a bytes instance.
2472
Christian Heimesa872de52008-12-05 08:26:55 +00002473- Issue #4533: File read operation was dreadfully slow due to a slowly
2474 growing read buffer. Fixed by using the same growth rate algorithm as
2475 Python 2.x.
2476
Antoine Pitrou5504e892008-12-06 21:27:53 +00002477- Issue #4509: Various issues surrounding resize of bytearray objects to
2478 which there are buffer exports (e.g. memoryview instances).
2479
Georg Brandlf9734072008-12-07 15:30:06 +00002480- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2481 method on file objects with closefd=False. The file descriptor is still
2482 kept open but the file object behaves like a closed file. The ``FileIO``
2483 object also got a new readonly attribute ``closefd``.

Walter Dörwaldc1651a02009-05-03 22:55:55 +00002492- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2493 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2494 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2495 of using the replace error handler in PyUnicode_DecodeUTF8().
