13-----------------
14
Victor Stinner4aae1eb2010-06-24 22:08:25 +000015- Issue #8949: "z" format of PyArg_Parse*() functions doesn't accept bytes
16 objects, as described in the documentation.
17
Victor Stinner0fe25a42010-06-17 23:08:50 +000018- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
Victor Stinner2cd12522010-06-17 23:17:37 +000019 Fix the encoding of the modules filename. Patch written by Amaury Forgeot
20 d'Arc.
Victor Stinner0fe25a42010-06-17 23:08:50 +000021
Mark Dickinsond35a32e2010-06-17 12:33:22 +000022- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
23 compilation code dealing with unary minus applied to a constant.
24 The removed code was mutating the ST, causing a second compilation
25 to fail.
26
Victor Stinner554f3f02010-06-16 23:33:54 +000027- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
28 mode raises unicode errors. The encoder only supports "strict" and "replace"
29 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000030 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000031
Victor Stinner06e49dd2010-06-13 18:21:50 +000032- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
33 formats if the string contains a null byte/character. Write unit tests for
34 string formats.
35
Nick Coghlan5e76e942010-06-12 13:42:46 +000036- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
37 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
38 location of the raised exception.
39
Victor Stinner313a1202010-06-11 23:56:51 +000040- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
41 filenames and enable os.fsencode().
42
Benjamin Peterson285a6892010-06-22 19:21:52 +000043- Issue #9058: Remove assertions about INT_MAX in UnicodeDecodeError.
44
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000045- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
46 the interpreter with characters outside the Basic Multilingual Plane
47 (higher than 0x10000).
48
Mark Dickinsonc7301312010-06-10 16:05:10 +000049- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
50 raise TypeError instead of giving a DeprecationWarning when a float
51 is parsed using the 'L' code (for long long). (All other integer
52 codes already raise TypeError in this case.)
53
Victor Stinner600d3be2010-06-10 12:00:55 +000054- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
55 enable shortcuts for upper case encoding name. Add also a shortcut for
56 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
57
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000058- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
59 doesn't support "char buffer" anymore in Python3.
60
61- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
62 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
63 like bytearray.
64
Victor Stinner33109a12010-05-28 21:55:10 +000065- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
66 used anymore and it was never documented.
67
Benjamin Peterson95304522010-06-08 14:57:22 +000068- In the str.format(), raise a ValueError when indexes to arguments are too
69 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000070
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000071- Issue #2844: Make int('42', n) consistently raise ValueError for
72 invalid integers n (including n = -909).
73
Mark Dickinsondc787d22010-05-23 13:33:13 +000074- Issue #8188: Introduce a new scheme for computing hashes of numbers
75 (instances of int, float, complex, decimal.Decimal and
76 fractions.Fraction) that makes it easy to maintain the invariant
77 that hash(x) == hash(y) whenever x and y have equal value.
78
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000079- Issue #8748: Fix two issues with comparisons between complex and integer
80 objects. (1) The comparison could incorrectly return True in some cases
81 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
82 (2) The comparison raised an OverflowError for large integers, leading
83 to unpredictable exceptions when combining integers and complex objects
84 in sets or dicts.
85
Victor Stinner7d79b8b2010-05-19 20:40:50 +000086- Issue #8766: Initialize _warnings module before importing the first module.
87 Fix a crash if an empty directory called "encodings" exists in sys.path.
88
Victor Stinner9ca9c252010-05-19 16:53:30 +000089- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
90 encoding and surrogateespace error handler instead of the locale encoding to
91 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
92
Victor Stinner372ac5e2010-05-17 01:26:01 +000093- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
94 (instead of strict) error handler to escape surrogates
95
Victor Stinnerae6265f2010-05-15 16:27:27 +000096- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
97 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000098 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
99 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +0000100
Victor Stinner59e62db2010-05-15 13:14:32 +0000101- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
102 error handler, not only the default error handler (strict)
103
Victor Stinnerb744ba12010-05-15 12:27:16 +0000104- Issue #8610: Load file system codec at startup, and display a fatal error on
105 failure. Set the file system encoding to utf-8 (instead of None) if getting
106 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
107
Victor Stinner0964ee12010-04-30 16:48:45 +0000108- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
109 PyUnicode_FromString() to support surrogates in the filename and use the
110 right encoding
111
Georg Brandl8569e582010-05-19 20:57:08 +0000112- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
113
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000114- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
115
Benjamin Petersonfb886362010-04-24 18:21:17 +0000116- Issue #8419: Prevent the dict constructor from accepting non-string keyword
117 arguments.
118
Victor Stinner14284c22010-04-23 12:02:30 +0000119- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
120 indirectly Python signal handlers anymore because mywrite() ignores
121 exceptions (KeyboardInterrupt)
122
Victor Stinner31be90b2010-04-22 19:38:16 +0000123- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
124 unicode string (eg. backslashreplace)
125
Victor Stinnerdcb24032010-04-22 12:08:36 +0000126- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
127 you have to convert your bytearray filenames to bytes
128
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000129- Issue #7332: Remove the 16KB stack-based buffer in
130 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
131 benefit compared to the dynamic memory allocation fallback. Patch by
132 Charles-François Natali.
133
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000134- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
135 passed to bytes or bytearray.
136
Philip Jenvey0805ca32010-04-07 04:04:10 +0000137- Issue #7301: Add environment variable $PYTHONWARNINGS.
138
Benjamin Petersond856ab62010-04-06 21:55:16 +0000139- Issue #8329: Don't return the same lists from select.select when no fds are
140 changed.
141
Mark Dickinson3318d292010-04-06 16:53:17 +0000142- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
143 on 64-bit machines. The shift count for either left or right shift is
144 permitted to be up to sys.maxsize.
145
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000146- Ensure that tokenization of identifiers is not affected by locale.

153 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000154
Victor Stinner120c2122010-03-25 00:30:28 +0000155- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
156 is unknown

159
Mark Dickinsond59b4162010-03-13 11:34:40 +0000160- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
161 PyMemberDefs could produce an internal error; raise TypeError instead.
162
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000163- Issue #7845: Rich comparison methods on the complex type now return
164 NotImplemented rather than raising a TypeError when comparing with an
165 incompatible type; this allows user-defined classes to implement their own
166 comparisons with complex.
167
Victor Stinner52f6dd72010-03-12 14:45:56 +0000168- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
169 (SIGINT). If an error occurs while importing the site module, the error is
170 printed and Python exits. Initialize the GIL before importing the site
171 module.
172
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000173- Issue #7173: Generator finalization could invalidate sys.exc_info().

197 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
198 and PyOS_string_to_double instead. See issue #5835 for the original
199 deprecations.
200
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000201- Issue #7385: Fix a crash in `MemoryView_FromObject` when
202 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
203
Mark Dickinsonbc099642010-01-29 17:27:24 +0000204- Issue #7788: Fix an interpreter crash produced by deleting a list
205 slice with very large step value.
206
Eric Smithf7bb5782010-01-27 00:44:57 +0000207- Issue #7766: Change sys.getwindowsversion() return value to a named
208 tuple and add the additional members returned in an OSVERSIONINFOEX
209 structure. The new members are service_pack_major, service_pack_minor,
210 suite_mask, and product_type.
211
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000212- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
213 could crash in many places because of the PyByteArray_AS_STRING() macro
214 returning NULL. The macro now returns a statically allocated empty
215 string instead.
216
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000217- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
218 where the right hand operand is a set of constants, by turning the set into
219 a frozenset and pre-building it as a constant. The comparison operation
220 is made against the constant instead of building a new set each time it is
221 executed (a similar optimization already existed which turned a list of
222 constants into a pre-built tuple). Patch and additional tests by Dave
223 Malcolm.
224
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000225- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
226 methods of bytes, bytearray and unicode objects by using a common
227 implementation based on stringlib's fast search. Patch by Florent Xicluna.
228

230 alpha 2, including: (1) a serious 'wrong output' bug that could
231 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
232 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000233 strings corresponding to subnormal values, (3) a memory leak for
234 some values large enough to cause overflow, and (4) a number of
235 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000236
Benjamin Petersonaea44282010-01-04 01:10:28 +0000237- The __complex__ method is now looked up on the class of instances to make it
238 consistent with other special methods.

242
Benjamin Petersond12362a2009-12-30 19:44:54 +0000243- Issue #7604: Deleting an unset slotted attribute did not raise an
244 AttributeError.

247 negative zero) in ** operator. The behaviour now conforms to that
248 described in C99 Annex F.
249
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000250- Issue #1811: improve accuracy and cross-platform consistency for
251 true division of integers: the result of a/b is now correctly
252 rounded for ints a and b (at least on IEEE 754 platforms), and in
253 particular does not depend on the internal representation of an int.
254
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000255- Issue #6834: replace the implementation for the 'python' and 'pythonw'
256 executables on OSX.
257
258 These executables now work properly with the arch(1) command:
259 ``arch -ppc python`` will start a universal binary version of python
260 in PPC mode (unlike previous releases).
261
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000262- Issue #7466: segmentation fault when the garbage collector is called
263 in the middle of populating a tuple. Patch by Florent Xicluna.

277 implement the relevant rich comparison methods.
278
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000279- Issue #7298: fixes for range and reversed(range(...)). Iteration
280 over range(a, b, c) incorrectly gave an empty iterator when a, b and
281 c fit in C long but the length of the range did not. Also fix
282 several cases where reversed(range(a, b, c)) gave wrong results, and
283 fix a refleak for reversed(range(a, b, c)) with large arguments.
284
Raymond Hettingerfc438512009-11-01 20:55:33 +0000285- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitrouf978fac2010-05-21 17:25:34 +0000395- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
396 embedders of the interpreter to set sys.argv without also modifying
397 sys.path. This helps fix `CVE-2008-5983
398 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
399

429 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
430 should used for accessing the d_type and d_name members of structures
431 using PyDescr_COMMON.

471
Mark Dickinson9b88b912010-06-11 10:46:57 +0000472- Issue #8188: Comparisons between Decimal and Fraction objects are
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000473 now permitted, returning a result based on the exact numerical
474 values of the operands. This builds on issue #2531, which allowed
475 Decimal-to-float comparisons; all comparisons involving numeric
476 types (bool, int, float, complex, Decimal, Fraction) should now
477 act as expected.

606
Ronald Oussorenac764d32010-05-05 15:32:33 +0000607- Issue #8621: uuid.uuid4() returned the same sequence of values in the
608 parent and any children created using ``os.fork`` on MacOS X 10.6.
609
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000610- Issue #8567: Fix precedence of signals in Decimal module: when a
611 Decimal operation raises multiple signals and more than one of those
612 signals is trapped, the specification determines the order in which
613 the signals should be handled. In many cases this order wasn't
614 being followed, leading to the wrong Python exception being raised.
615
Antoine Pitrou6be88762010-05-03 16:48:20 +0000616- Issue #7865: The close() method of :mod:`io` objects should not swallow
617 exceptions raised by the implicit flush(). Also ensure that calling
618 close() several times is supported. Patch by Pascal Chambon.
619
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000620- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
621 gc.DEBUG_STATS.
622
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000623- Issue #8354: The siginterrupt setting is now preserved for all signals,
624 not just SIGCHLD.
625
Georg Brandl25106ce2010-05-21 21:49:47 +0000626- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000627 webbrowser.get("safari").
628
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000629- Issue #8464: tarfile no longer creates files with execute permissions set
630 when mode="w|" is used.
631
Antoine Pitroubf043492010-04-29 10:11:46 +0000632- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
633 of the Linux kernel. Patch by Yaniv Aknin.
634
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000635- Issue #8295: Added shutil.unpack_archive.
636
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000637- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
638 It should correctly return an empty response now.
639
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000640- Issue #8546: Reject None given as the buffering argument to _pyio.open.
641
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000642- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
643 Sridhar Ratnakumar.
644
R. David Murrayad78d152010-04-27 02:45:53 +0000645- Issue #6656: fix locale.format_string to handle escaped percents
646 and mappings.
647
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000648- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
649 where the method could block indefinitely if called just before the
650 event loop started running. This also fixes the occasional freezes
651 witnessed in test_httpservers.
652
Antoine Pitrou40f08742010-04-24 22:04:40 +0000653- Issue #8524: When creating an SSL socket, the timeout value of the
654 original socket wasn't retained (instead, a socket with a positive timeout
655 would be turned into a non-blocking SSL socket).
656
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000657- Issue #5103: SSL handshake would ignore the socket timeout and block
658 indefinitely if the other end didn't respond.
659
660- The do_handshake() method of SSL objects now adjusts the blocking mode of
661 the SSL structure if necessary (as other methods already do).
662
Victor Stinner13bb71c2010-04-23 21:41:56 +0000663- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
664 and bytes strings for environment keys and values
665
Victor Stinner4d078042010-04-23 19:28:32 +0000666- Issue #8467: Pure Python implementation of subprocess encodes the error
667 message using surrogatepass error handler to support surrogates in the
668 message
669
Victor Stinner349fd522010-04-23 10:56:17 +0000670- Issue #8468: bz2.BZ2File() accepts str with surrogates and bytes filenames
671
Sean Reifscheider13daf122010-04-23 09:29:52 +0000672- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
673 the string "python" as the *ident*. openlog() arguments are all optional
674 and keywords.
675
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000676- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
677 a non-infinite timeout. Also make that method friendlier with applications
678 wanting to continue using the socket in clear-text mode, by disabling
679 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
680
Antoine Pitrou7062db82010-04-22 13:30:10 +0000681- Issue #8496: make mailcap.lookup() always return a list, rather than an
682 iterator. Patch by Gregory Nofi.
683
Victor Stinner35466c52010-04-22 11:23:23 +0000684- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
685 collation name contains a surrogate character.
686
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000687- Issue #8484: Load all ciphers and digest algorithms when initializing
688 the _ssl extension, such that verification of some SSL certificates
689 doesn't fail because of an "unknown algorithm".
690
Tarek Ziadéfb437512010-04-20 08:57:33 +0000691- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
692
Victor Stinnere125f132010-05-15 21:04:43 +0000693- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000694 shutil.copytree.
695
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000696- Issue #4814: timeout parameter is now applied also for connections resulting
697 from PORT/EPRT commands.
698
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000699- Issue #8463: added missing reference to bztar in shutil's documentation.
700
Ronald Oussoren84151202010-04-18 20:46:11 +0000701- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
702 (as long as the user didn't specify 'automatic proxy configuration').
703
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000704- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
705 code as stated in RFC-959 at chapter 5.4.
706
Victor Stinner738446f02010-04-18 00:00:44 +0000707- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
708 surrogates.
709
Antoine Pitrou0454af92010-04-17 23:51:58 +0000710- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000711 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000712
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000713- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
714 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
715
Victor Stinner0e59cc32010-04-16 23:49:32 +0000716- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
717 the current working directory.
718
Victor Stinner5bfe1462010-04-16 13:28:05 +0000719- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
720 using backslashreplace error handler

727
R. David Murrayd48739f2010-04-14 18:59:18 +0000728- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
729
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000730- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
731 module now takes an optional timeout argument in seconds. Timeout support
732 relies on the system threading library, so as to avoid a semi-busy wait
733 loop.
734
Victor Stinner485fb562010-04-13 11:07:24 +0000735- Issue #8383: pickle and pickletools use surrogatepass error handler when
736 encoding unicode as utf8 to support lone surrogates and stay compatible with
737 Python 2.x and 3.0
738
R. David Murrayb2416e52010-04-12 16:58:02 +0000739- Issue #7585: difflib context and unified diffs now place a tab between
740 filename and date, conforming to the 'standards' they were originally
741 designed to follow. This improves compatibility with patch tools.
742
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000743- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
744 character sets will now consistently use a Content-Transfer-Encoding of
745 7bit rather than sometimes being marked as 8bit.
746
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000747- Issue #8375: test_distutils now checks if the temporary directory are still
748 present before it cleans them.
749
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000750- Issue #8374: Update the internal alias table in the :mod:`locale` module
751 to cover recent locale changes and additions.
752
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000753- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
754 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
755 and `ssl.OPENSSL_VERSION_NUMBER`.
756
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000757- Add functools.total_ordering() and functools.cmp_to_key().
758
Mark Dickinson089b00c2010-04-03 15:51:03 +0000759- Issue #8257: The Decimal construct now accepts a float instance
760 directly, converting that float to a Decimal of equal value:
761
762 >>> Decimal(1.1)
763 Decimal('1.100000000000000088817841970012523233890533447265625')
764
Mark Dickinson98127c32010-04-03 11:18:52 +0000765- Issue #8294: The Fraction constructor now accepts Decimal and float
766 instances directly.
767
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000768- Issue #7279: Comparisons involving a Decimal signaling NaN now
769 signal InvalidOperation instead of returning False. (Comparisons
770 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
771 are now hashable; Decimal signaling NaNs remain unhashable.
772
773- Issue #2531: Comparison operations between floats and Decimal
774 instances now return a result based on the numeric values of the
775 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000776 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000777 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000778
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000779- Added a subtract() method to collections.Counter().
780
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000781- Issue #8233: When run as a script, py_compile.py optionally takes a single
782 argument `-` which tells it to read files to compile from stdin. Each line
783 is read on demand and the named file is compiled immediately. (Original
784 patch by Piotr Ożarowski).
785
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000786- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
787 form feed (0x0C) are now considered linebreaks, as specified in Unicode
788 Standard Annex #14. See issue #7643.
789 http://www.unicode.org/reports/tr14/
790
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000791- Comparisons using one of <, <=, >, >= between a complex instance and
792 a Fractions instance now raise TypeError instead of returning
793 True/False. This makes Fraction <=> complex comparisons consistent with
794 int <=> complex, float <=> complex, and complex <=> complex comparisons.
795
Antoine Pitrou39b35432010-03-23 00:25:54 +0000796- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
797 some methods (such as oss_mixer_device.fileno()) were not available.
798 Initial patch by Bertrand Janin.
799
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000800- Issue #8205: Remove the "Modules" directory from sys.path when Python is
801 running from the build directory (POSIX only).
802
Antoine Pitrou910bd512010-03-22 20:11:09 +0000803- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
804 didn't support chflags() (for example ZFS under FreeBSD). The error is
805 now silenced.
806
R. David Murrayca2edce2010-03-22 17:48:48 +0000807- Issue #7860: platform.uname now reports the correct 'machine' type
808 when Python is running in WOW64 mode on 64 bit Windows.
809
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000810- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
811 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
812 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000813
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000814- Issue #4282: Fix the main function of the profile module for a non-ASCII
815 script, open the file in binary mode and not in text mode with the default
816 (utf8) encoding.
817
Florent Xicluna54467e02010-03-21 12:29:50 +0000818- Issue #8179: Fix macpath.realpath() on a non-existing path.
819
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000820- Issue #8024: Update the Unicode database to 5.2.
821
Benjamin Peterson00888932010-03-18 22:37:38 +0000822- Issue #8168: py_compile now handles files with utf-8 BOMS.
823
Benjamin Peterson689a5582010-03-18 22:29:52 +0000824- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
825 detected.
826
Martin v. Löwis4b003072010-03-16 13:19:21 +0000827- Issue #6716/2: Backslash-replace error output in compilall.
828
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000829- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
830 with Tcl/Tk-8.5.
831
Matthias Klosec33b9022010-03-16 00:36:26 +0000832- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000834- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
835 the locale.
836
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000837- The internals of the subprocess module on POSIX systems have been replaced
838 by an extension module (_posixsubprocess) so that the fork()+exec() can be
839 done safely without the possibility of deadlock in multithreaded applications.
840
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000841- subprocess.Popen now has restore_signals and start_new_session features.
842 The default of restore_signals=True is a new behavior compared to earlier
843 Python versions. This means that signals such as SIGPIPE are not ignored
844 by default in subprocesses launched by Python (Issue #1652).
845
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000846- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The
847 cElementTree module is updated too.
848

857
Gerhard Häringf9cee222010-03-05 15:20:03 +0000858- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure

893
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000894- Issue #7597: curses.use_env() can now be called before initscr().

Brett Cannonef7d6722010-02-19 16:04:36 +0000902- Issue #7361: Importlib was not properly checking the number of bytes in
903 bytecode file when it was less then 8 bytes.
904
Mark Dickinson84230a12010-02-18 14:49:50 +0000905- Issue #7633: In the decimal module, Context class methods (with the
906 exception of canonical and is_canonical) now accept instances of int
907 and long wherever a Decimal instance is accepted, and implicitly
908 convert that argument to Decimal. Previously only some arguments
909 were converted.
910
R. David Murray1f449142010-02-11 00:15:05 +0000911- Issue #7835: shelve should no longer produce mysterious warnings during
912 interpreter shutdown.
913
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000914- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
915 in XML processing instructions and comments. These raw characters are
916 allowed by the XML specification, and are necessary when outputting e.g.
917 PHP code in a processing instruction. Patch by Neil Muller.
918
Antoine Pitrouc77dd322010-02-09 16:51:16 +0000919- Issue #6233: ElementTree failed converting unicode characters to XML
920 entities when they could't be represented in the requested output
921 encoding. Patch by Jerry Chen.
922

924 specify the compression type.
925
Antoine Pitroub6375f12010-02-04 20:23:24 +0000926- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
927 specified, rather than fall through to AF_PACKET (in the `socket` module).
928 Also, raise ValueError rather than TypeError when an unknown TIPC address
929 type is specified. Patch by Brian Curtin.
930
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000931- Issue #6939: Fix file I/O objects in the `io` module to keep the original
932 file position when calling `truncate()`. It would previously change the
933 file position to the given argument, which goes against the tradition of
934 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
935
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000936- Issue #7610: Reworked implementation of the internal
937 :class:`zipfile.ZipExtFile` class used to represent files stored inside
938 an archive. The new implementation is significantly faster and can
939 be wrapped in a :class:`io.BufferedReader` object for more speedups.
940 It also solves an issue where interleaved calls to `read()` and
941 `readline()` give wrong results. Patch by Nir Aides.
942
Jesse Noller1f0b6582010-01-27 03:36:01 +0000943- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,
944 allowing for a maximum number of tasks within the pool to be completed by
945 the worker before that worker is terminated, and a new one created to
946 replace it.

980 file). Initial patch by Collin Winter.
981
Tarek Ziadéaf77a2f2010-01-08 23:57:53 +0000982- Issue #7617: Make sure distutils.unixccompiler.UnixCCompiler recognizes

Victor Stinnere125f132010-05-15 21:04:43 +00001009 MSVC XML Manifest file in text mode so string patterns can be used
Tarek Ziadéc60ea322009-12-21 23:12:41 +00001010 in regular expressions.
1011

1020 raise a TypeError when given an `str` object (rather than a `bytes`-like
1021 object). Patch by Victor Stinner and Florent Xicluna.
1022
Benjamin Petersonbf5ff762009-12-13 19:25:34 +00001023- Issue #7349: Make methods of file objects in the io module accept None as an
1024 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1025 the same as passing no argument.
1026
Lars Gustäbel365aff32009-12-13 11:42:29 +00001027- Issue #7357: tarfile no longer suppresses fatal extraction errors by

1055
Tarek Ziadéacafc2d2009-11-29 22:24:57 +00001056- Issue #7408: Fixed distutils.tests.sdist so it doesn't check for group
1057 ownership when the group is not forced, because the group may be different
1058 from the user's group and inherit from its container when the test is run.
1059
Antoine Pitrou7b0d4a22009-11-28 16:12:28 +00001060- Issue #4486: When an exception has an explicit cause, do not print its

1103
Nick Coghlan260bd3e2009-11-16 06:49:25 +00001104- Issue #6816: runpy now provides a run_path function that allows Python code
1105 to execute file paths that refer to source or compiled Python files as well
1106 as zipfiles, directories and other valid sys.path entries that contain a
1107 __main__.py file. This allows applications that run other Python scripts to
1108 support the same flexibility as the CPython command line itself.
1109
Antoine Pitrou45d61a32009-11-13 22:35:18 +00001110- Issue #7318: multiprocessing now uses a timeout when it fails to establish
1111 a connection with another process, rather than looping endlessly. The
1112 default timeout is 20 seconds, which should be amply sufficient for

1114
Antoine Pitrouc63ecee2009-11-10 21:34:48 +00001115- Issue #7197: Allow unittest.TextTestRunner objects to be pickled and

1125
Antoine Pitrou434736a2009-11-10 18:46:01 +00001126- Issue #3001: Add a C implementation of recursive locks which is used by
Victor Stinnere125f132010-05-15 21:04:43 +00001127 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001128 recursive locks as fast as regular non-recursive locks (previously,
1129 they were slower by 10x to 15x).
1130
Antoine Pitroub0872682009-11-09 16:08:16 +00001131- Issue #7282: Fix a memory leak when an RLock was used in a thread other

1143
Antoine Pitrou03f13442009-11-02 11:36:51 +00001144- Issue #6896: mailbox.Maildir now invalidates its internal cache each time
1145 a modification is done through it. This fixes inconsistencies and test
1146 failures on systems with slightly bogus mtime behaviour.
1147
Gregory P. Smith50467882009-11-01 18:42:17 +00001148- Issue #7246 & Issue #7208: getpass now properly flushes input before
1149 reading from stdin so that existing input does not confuse it and
1150 lead to incorrect entry or an IOError. It also properly flushes it
1151 afterwards to avoid the terminal echoing the input afterwards on
1152 OSes such as Solaris.
1153
Mark Dickinsona2d1fe02009-10-29 12:23:02 +00001154- Issue #7233: Fix a number of two-argument Decimal methods to make
1155 sure that they accept an int or long as the second argument. Also
1156 fix buggy handling of large arguments (those with coefficient longer
1157 than the current precision) in shift and rotate.
1158
Lars Gustäbel1440df22009-10-29 09:39:47 +00001159- Issue #4750: Store the basename of the original filename in the gzip FNAME

Brett Cannon69194272009-07-20 04:23:48 +00001284- Add importlib.abc.ExecutionLoader to represent the PEP 302 protocol for
1285 loaders that allow for modules to be executed. Both importlib.abc.PyLoader
1286 and PyPycLoader inherit from this class and provide implementations in
1287 relation to other methods required by the ABCs.
1288
Brett Cannon64ef00f2009-07-20 03:19:18 +00001289- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like
1290 the documentation said it did even though the code in PyLoader relied on the

Alexander Belopolsky75f94c22010-06-21 15:21:14 +00001338- Issue #9005: Prevent utctimetuple() from producing year 0 or year
1339 10,000. Prior to this change, timezone adjustment in utctimetuple()
1340 could produce tm_year value of 0 or 10,000. Now an OverflowError is
1341 raised in these edge cases.
1342
Alexander Belopolskyca94f552010-06-17 18:30:34 +00001343- Issue #6641: The ``datetime.strptime`` method now supports the
1344 ``%z`` directive. When the ``%z`` directive is present in the
1345 format string, an aware ``datetime`` object is returned with
1346 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1347 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1348 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1349 without ``%z`` is discarded.
1350
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001351- Issue #5094: The ``datetime`` module now has a simple concrete class
1352 implementing ``datetime.tzinfo`` interface. Instances of the new
1353 class, ``datetime.timezone``, return fixed name and UTC offset from
1354 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1355 method always returns ``None``. A class attribute, ``utc`` contains
1356 an instance representing the UTC timezone. Original patch by Rafe
1357 Kaplan.
1358
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001359- Issue #8973: Add __all__ to struct module; this ensures that

1361
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001362- Issue #3129: Trailing digits in struct format string are no longer ignored.
Victor Stinnerda0eca42010-06-11 21:50:30 +00001363 For example, "1" or "ilib123" are now invalid formats and cause
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001364 ``struct.error`` to be raised. Patch by Caleb Deveraux.
Alexander Belopolsky177e8532010-06-11 16:04:59 +00001365
Stefan Kraha3ac44e2010-06-08 14:00:52 +00001366- Issue #7384: If the system readline library is linked against ncurses,
1367 the curses module must be linked against ncurses as well. Otherwise it
1368 is not safe to load both the readline and curses modules in an application.
1369
Brian Curtin60853212010-05-26 17:43:50 +00001370- Issue #2810: Fix cases where the Windows registry API returns

1372
Mark Dickinson4c8a9a22010-05-15 17:02:38 +00001373- Issue #8692: Optimize math.factorial: replace the previous naive
1374 algorithm with an improved 'binary-split' algorithm that uses fewer
1375 multiplications and allows many of the multiplications to be
1376 performed using plain C integer arithmetic instead of PyLong
1377 arithmetic. Also uses a lookup table for small arguments.
1378
Mark Dickinson85eacea2010-05-10 16:27:45 +00001379- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1380 overflow checks in the audioop module.
1381
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001382- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1383 calculating with integer arithmetic instead of float arithmetic internally):
1384 the result is now always correctly rounded, and is equivalent to td /
1385 timedelta(seconds=1).
1386
Mark Dickinson7c186e22010-04-20 22:32:49 +00001387- Issue #2706: Allow division of a timedelta by another timedelta:

1389 and divmod(timedelta, timedelta) are all supported.
1390
Victor Stinnerfebecd82010-04-16 12:07:30 +00001391- Issue #8314: Fix unsigned long long bug in libffi on Sparc v8.
1392
Mark Dickinsonc5935772010-04-03 15:54:36 +00001393- Issue #8300: When passing a non-integer argument to struct.pack with any
1394 integer format code, struct.pack first attempts to convert the non-integer
1395 using its __index__ method. If that method is non-existent or raises
1396 TypeError it goes on to try the __int__ method, as described below.
1397
Matthias Klosea8349752010-03-15 13:25:28 +00001398- Issue #8142: Update libffi to the 3.0.9 release.

1647 leak-chasing test runs give sensible results. The previous method of
1648 reaping threads could return successfully while some Thread objects were
1649 still referenced. This also introduces a new private function:
1650 :func:`_thread._count()`.
1651
R. David Murray27144602009-10-19 15:26:16 +00001652- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1653 longer runs the risk of causing the worker thread to fail.
1654
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001655- Issue #7055: test___all__ now greedily detects all modules which have an
1656 __all__ attribute, rather than using a hardcoded and incomplete list.

1660 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001661
Mark Dickinson2e304402009-10-04 18:43:54 +00001662- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1663
Brett Cannon3c273842009-07-20 00:14:29 +00001664- Fixed tests in importlib.test.source.test_abc_loader that were masking
1665 the proper exceptions that should be raised for missing or improper code
1666 object bytecode.
1667
Brett Cannonb49c70c2009-07-15 04:08:33 +00001668- Removed importlib's custom test discovery code and switched to

1755 are always None now.
1756
Antoine Pitroud9dfaa92009-06-04 20:32:06 +00001757- Issue #6137: The pickle module now translates module names when loading
1758 or dumping pickles with a 2.x-compatible protocol, in order to make data
1759 sharing and migration easier. This behaviour can be disabled using the
1760 new `fix_imports` optional argument.

1813
Eric Smith41669ca2009-05-23 14:23:22 +00001814- Issue #6089: Fixed str.format with certain invalid field specifiers
1815 that would raise SystemError.
1816
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001817- Issue #5982: staticmethod and classmethod now expose the wrapped
1818 function with __func__.
1819
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001820- Added support for multiple context managers in the same with-statement.
1821 Deprecated contextlib.nested() which is no longer needed.

Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001823- Issue #5829: complex("1e500") no longer raises OverflowError. This
1824 makes it consistent with float("1e500") and interpretation of real
1825 and imaginary literals.
1826
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001827- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

1830
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001831- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1832 (1) inf and nan strings with trailing whitespace were incorrectly
1833 rejected; (2) parsing of strings representing infinities and nans
1834 was locale aware; and (3) the interpretation of fromhex('-nan')
1835 didn't match that of float('-nan').

Benjamin Petersonaccdca52009-05-06 23:26:59 +00001837Library
1838-------
1839
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001840- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1841

1843
R. David Murray1f1b9d32009-05-27 20:56:59 +00001844- Issue #6121: pydoc now ignores leading and trailing spaces in the
1845 argument to the 'help' function.
1846
Georg Brandlfaf41492009-05-26 18:31:11 +00001847- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1848 arguments for strings with a space in them.
1849
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001850- collections.namedtuple() was not working with the following field
1851 names: cls, self, tuple, itemgetter, and property.
1852
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001853- In unittest, using a skipping decorator on a class is now equivalent to
1854 skipping every test on the class. The ClassTestSuite class has been removed.
1855
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001856- Issue #6050: Don't fail extracting a directory from a zipfile if
1857 the directory already exists.
1858
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001859- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1860 than an int, which makes some operations possible under 64-bit Linux (e.g.
1861 DN_MULTISHOT with F_NOTIFY).
1862
Antoine Pitrou716c4442009-05-23 19:04:03 +00001863- Issue #5761: Add the name of the underlying file to the repr() of various
1864 IO objects.
1865
R. David Murraycaa27b72009-05-23 18:49:56 +00001866- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1867 by Musashi Tamura, tests by Marcin Bachry.
1868
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001869- Issue #1983: Fix functions taking or returning a process identifier to use
1870 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1871 a process identifier type wider than the standard C integer type.
1872
R. David Murray87e20742009-05-23 01:30:26 +00001873- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1877 deepcopy()ing.
1878

1884
Antoine Pitroue4501852009-05-14 18:55:55 +00001885- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1886 library. This means, for example, that opening an UTF-16 text file in
1887 append mode doesn't add a BOM at the end of the file if the file isn't
1888 empty.
1889
R. David Murray74b89242009-05-13 17:33:03 +00001890- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1891 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1892 corrects a pydoc regression.
1893
R. David Murray99352742009-05-07 18:24:38 +00001894- Issue 5955: aifc's close method did not close the file it wrapped,
1895 now it does. This also means getfp method now returns the real fp.
1896
Benjamin Peterson932073a2009-05-23 16:14:33 +00001897Installation
1898------------

Brett Cannon1262e7c2009-05-11 01:47:11 +00001924Tests
1925-----
1926
1927- Issue 5442: Tests for importlib were not properly skipping case-sensitivity
1928 tests on darwin even when the OS was installed on a case-sensitive

1932
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001933What's New in Python 3.1 beta 1?
1934================================

Benjamin Peterson5c5f3de2009-05-06 20:43:28 +00001936*Release date: 2009-05-06*
Benjamin Petersonbd35b032009-04-04 23:16:41 +00001937
1938Core and Builtins
1939-----------------
1940
Mark Dickinson865e01a2009-05-07 16:37:01 +00001941- Issue #5914: Add new C API function PyOS_string_to_double, and
1942 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1943
Eric Smith741191f2009-05-06 13:08:15 +00001944- Issue #3382: float.__format__, complex.__format__, and %-formatting
1945 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1946 affects nan -> NAN and inf -> INF.
1947
Mark Hammond5a607a32009-05-06 08:04:54 +00001948- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1949 in all operations, including splitdrive, split, etc. splitunc() now issues
1950 a PendingDeprecation warning.
1951
Eric Smith63376222009-05-05 14:04:18 +00001952- Issue #5920: For float.__format__, change the behavior with the
1953 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1954 to be like 'g' but with at least one decimal point and with a
1955 default precision of 12. Previously, the behavior the same but with
1956 a default precision of 6. This more closely matches str(), and
1957 reduces surprises when adding alignment flags to the empty
1958 presentation type. This also affects the new complex.__format__ in
1959 the same way.
1960
Martin v. Löwis011e8422009-05-05 04:43:17 +00001961- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1962
R. David Murrayb18500d2009-05-04 22:59:07 +00001963- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1964 shadowed by classtype's, even if it was None. property now
1965 inserts the __doc__ into the subclass instance __dict__.
1966
Antoine Pitrou244651a2009-05-04 18:56:13 +00001967- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1968 sequences. Patch by Nick Barnes and Victor Stinner.
1969
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001970- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001971
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001972- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1973 received a new method, detach(). detach() disconnects the underlying stream
1974 from the buffer or text IO and returns it.
1975
Mark Dickinson33841c32009-05-01 15:37:04 +00001976- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1977 floats with absolute value over 1e50. Also remove length
1978 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1979 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001980
Eric Smith741191f2009-05-06 13:08:15 +00001981- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001982 format(complex(1, 2./3), '.5') now produces a sensible result.
1983
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001984- Issue #5864: Fix empty format code formatting for floats so that it
1985 never gives more than the requested number of significant digits.
1986
Eric Smith6dc46f52009-04-27 20:39:49 +00001987- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1988 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1989
Eric Smithcc32a112009-04-26 21:35:14 +00001990- Issue #5835: Deprecate PyOS_ascii_formatd.
1991
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001992- Issue #4971: Fix titlecase for characters that are their own
1993 titlecase, but not their own uppercase.
1994
Benjamin Peterson193152c2009-04-25 01:08:45 +00001995- Issue #5283: Setting __class__ in __del__ caused a segfault.
1996
Mark Dickinsonad476da2009-04-23 19:14:16 +00001997- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1998 z involves nans, infs or negative zeros.
1999
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00002000- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00002001
Mark Dickinsone6a076d2009-04-18 11:48:33 +00002002- Issue #1869 (and many duplicates): make round(x, n) correctly
2003 rounded for a float x, by using the decimal <-> binary conversions
2004 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2005 consistently agrees with format(x, '.2f').
2006
Benjamin Petersonae937c02009-04-18 20:54:08 +00002007- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2008 some builtin types.
2009
Eric Smith0923d1d2009-04-16 20:16:10 +00002010- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2011
Eric Smith35e84722009-04-16 20:21:28 +00002012- Issue #5515: str.format() type 'n' combined with commas and leading
2013 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002014
2015- Implement PEP 378, Format Specifier for Thousands Separator, for
2016 floats.
2017
Mark Dickinson3370cce2009-04-17 22:40:53 +00002018- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002019 1e11, not 1e12. This avoids printing 13 significant digits in
2020 situations where only 12 of them are correct. Example problem
2021 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2022 long time.)
2023
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002024- Issue #1580: On most platforms, use a 'short' float repr: for a
2025 finite float x, repr(x) now outputs a string based on the shortest
2026 sequence of decimal digits that rounds to x. Previous behaviour was
2027 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002028 Another minor difference is that the new repr switches to
2029 exponential notation at 1e16 instead of the previous 1e17; this
2030 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002031
2032 There's a new sys attribute sys.float_repr_style, which takes
2033 the value 'short' to indicate that we're using short float repr,
2034 and 'legacy' if the short float repr isn't available for one
2035 reason or another.
2036
2037 The float repr change involves incorporating David Gay's 'perfect
2038 rounding' code into the Python core (it's in Python/dtoa.c). As a
2039 secondary consequence, all string-to-float and float-to-string
2040 conversions (including all float formatting operations) will be
2041 correctly rounded on these platforms.
2042
2043 See issue 1580 discussions for details of platforms for which

2050 the types string.maketrans() is supposed to work with, and mirrors the
2051 methods available on the str class.

Georg Brandl1cdd83c2009-04-05 20:24:29 +00002358- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002359 were suppressing all exceptions. These include list() and bytearray().
2360
Mark Dickinson1124e712009-01-28 21:25:58 +00002361- Issue #4707: round(x, n) now returns an integer if x is an integer.
2362 Previously it returned a float.
2363
Antoine Pitroub52ec782009-01-25 16:34:23 +00002364- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2365 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2366 evaluation loop is compiled with a new dispatch mechanism which gives
2367 speedups of up to 20%, depending on the system, on various benchmarks.
2368
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002369- Issue #4874: Most builtin decoders now reject unicode input.

2377 optional module state data.
2378
Mark Dickinson8055afd2009-01-17 10:04:45 +00002379- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2380 type to (void *).
2381
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002382- Issue #4935: The overflow checking code in the expandtabs() method common
2383 to str, bytes and bytearray could be optimized away by the compiler, letting
2384 the interpreter segfault instead of raising an error.
2385
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002386- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2387 __next__ method.
2388
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002389- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2390 function no longer attempt to call the __long__ slot to convert an object
2391 to an integer. Only the __int__ and __trunc__ slots are examined.

2396
Antoine Pitrouab868312009-01-10 15:40:25 +00002397- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2398 common cases are optimized thanks to a dedicated fast path and a moderate
2399 amount of loop unrolling.
2400
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002401- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2402 collecting the oldest generation) so that allocating lots of objects without
2403 destroying them does not show quadratic performance. Based on a proposal by
2404 Martin von Löwis at
2405 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2406
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002407- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002408 having been closed (for instance, a read() call could return some
2409 previously buffered data). Patch by Dmitry Vasiliev.
2410
Antoine Pitrou05608432009-01-09 18:53:14 +00002411- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2412 flag to work properly. Furthermore, when specifying -u, the text stdout
2413 and stderr streams have line-by-line buffering enabled (the default being
2414 to buffer arbitrary chunks of data).
2415
Raymond Hettinger35631532009-01-09 03:58:09 +00002416- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2417 instead of ints (reducing its size from 4 to 8 times thereby reducing
2418 Python's overall memory).
2419
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002420- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2421 an existing .py counterpart, override the co_filename attributes of all
2422 code objects if the original filename is obsolete (which can happen if the
2423 file has been renamed, moved, or if it is accessed through different paths).
2424 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2425
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002426- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2427 one byte. Also fixes the meaning of len() so that it returns the number of
2428 items, rather than the size in bytes.
2429
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002430- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2431
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002432- Issue #4747: When the terminal does not use utf-8, executing a script with
2433 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2434

2439 did not get collected.
2440
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002441- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2442 where the tp_hash and tp_dict slots are both NULL.
2443
Georg Brandlccc47b62008-12-28 11:44:14 +00002444- Issue #4759: None is now allowed as the first argument of
2445 bytearray.translate(). It was always allowed for bytes.translate().
2446
Skip Montanaro80072cb2008-12-23 03:51:14 +00002447- Added test case to ensure attempts to read from a file opened for writing
2448 fail.

2454
Antoine Pitrou621601a2008-12-17 23:18:19 +00002455- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

2460
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002461- Issue #2173: When getting device encoding, check that return value of
2462 nl_langinfo is not the empty string. This was causing silent build
2463 failures on OS X.
2464
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002465- Issue #4597: Fixed several opcodes that weren't always propagating
2466 exceptions.
2467
2468- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002469 context manager returns a value that cannot be converted to a bool.
2470
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002471- Issue #4445: Replace "sizeof(PyBytesObject)" with
2472 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2473 bytes instances. On a typical machine this saves 3 bytes of memory
2474 (on average) per allocation of a bytes instance.
2475
Christian Heimesa872de52008-12-05 08:26:55 +00002476- Issue #4533: File read operation was dreadfully slow due to a slowly
2477 growing read buffer. Fixed by using the same growth rate algorithm as
2478 Python 2.x.
2479
Antoine Pitrou5504e892008-12-06 21:27:53 +00002480- Issue #4509: Various issues surrounding resize of bytearray objects to
2481 which there are buffer exports (e.g. memoryview instances).
2482
Georg Brandlf9734072008-12-07 15:30:06 +00002483- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2484 method on file objects with closefd=False. The file descriptor is still
2485 kept open but the file object behaves like a closed file. The ``FileIO``
2486 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002487
Antoine Pitroubc420402008-12-07 20:14:49 +00002488- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2494
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002495- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2496 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2497 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2498 of using the replace error handler in PyUnicode_DecodeUTF8().
