12Core and Builtins
13-----------------
14
Victor Stinner0fe25a42010-06-17 23:08:50 +000015- Issue #6543: Write the traceback in the terminal encoding instead of utf-8.
16 Fix the encoding of the modules filename.
17
Mark Dickinsond35a32e2010-06-17 12:33:22 +000018- Issue #9011: Remove buggy and unnecessary (in 3.x) ST->AST
19 compilation code dealing with unary minus applied to a constant.
20 The removed code was mutating the ST, causing a second compilation
21 to fail.
22
Victor Stinner554f3f02010-06-16 23:33:54 +000023- Issue #850997: mbcs encoding (Windows only) handles errors argument: strict
24 mode raises unicode errors. The encoder only supports "strict" and "replace"
25 error handlers, the decoder only supports "strict" and "ignore" error
Victor Stinner2bdab242010-06-16 23:48:49 +000026 handlers. Patch written by Mark Hammond.
Victor Stinner554f3f02010-06-16 23:33:54 +000027
Victor Stinner06e49dd2010-06-13 18:21:50 +000028- Issue #8592: PyArg_Parse*() functions raise a TypeError for "y", "u" and "Z"
29 formats if the string contains a null byte/character. Write unit tests for
30 string formats.
31
Nick Coghlan5e76e942010-06-12 13:42:46 +000032- Issue #7490: to facilitate sharing of doctests between 2.x and 3.x test
33 suites, the IGNORE_EXCEPTION_DETAIL directive now also ignores the module
34 location of the raised exception.
35
Victor Stinner313a1202010-06-11 23:56:51 +000036- Issue #8969: On Windows, use mbcs codec in strict mode to encode and decode
37 filenames and enable os.fsencode().
38
Antoine Pitroucc0cfd32010-06-11 21:46:32 +000039- Issue #8941: decoding big endian UTF-32 data in UCS-2 builds could crash
40 the interpreter with characters outside the Basic Multilingual Plane
41 (higher than 0x10000).
42
Mark Dickinsonc7301312010-06-10 16:05:10 +000043- Issue #8950: (See also issue #5080). Py_ArgParse*() functions now
44 raise TypeError instead of giving a DeprecationWarning when a float
45 is parsed using the 'L' code (for long long). (All other integer
46 codes already raise TypeError in this case.)
47
Victor Stinner600d3be2010-06-10 12:00:55 +000048- Issue #8922: Normalize the encoding name in PyUnicode_AsEncodedString() to
49 enable shortcuts for upper case encoding name. Add also a shortcut for
50 "iso-8859-1" in PyUnicode_AsEncodedString() and PyUnicode_Decode().
51
Victor Stinner3dcb5ac2010-06-08 22:54:19 +000052- Issue #8838: Remove codecs.charbuffer_encode() function. The buffer protocol
53 doesn't support "char buffer" anymore in Python3.
54
55- Issue #8339: Remove "t#" format of PyArg_Parse*() functions, use "s#" or "s*"
56 instead. codecs.charbuffer_encode() now accepts modifiable buffer objects
57 like bytearray.
58
Victor Stinner33109a12010-05-28 21:55:10 +000059- Issue #8837: Remove "O?" format of PyArg_Parse*() functions. The format is no
60 used anymore and it was never documented.
61
Benjamin Peterson95304522010-06-08 14:57:22 +000062- In the str.format(), raise a ValueError when indexes to arguments are too
63 large.
Benjamin Peterson59a1b2f2010-06-07 22:31:26 +000064
Mark Dickinsonf9a5a8e2010-05-26 20:07:58 +000065- Issue #2844: Make int('42', n) consistently raise ValueError for
66 invalid integers n (including n = -909).
67
Mark Dickinsondc787d22010-05-23 13:33:13 +000068- Issue #8188: Introduce a new scheme for computing hashes of numbers
69 (instances of int, float, complex, decimal.Decimal and
70 fractions.Fraction) that makes it easy to maintain the invariant
71 that hash(x) == hash(y) whenever x and y have equal value.
72
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000073- Issue #8748: Fix two issues with comparisons between complex and integer
74 objects. (1) The comparison could incorrectly return True in some cases
75 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
76 (2) The comparison raised an OverflowError for large integers, leading
77 to unpredictable exceptions when combining integers and complex objects
78 in sets or dicts.
79
Victor Stinner7d79b8b2010-05-19 20:40:50 +000080- Issue #8766: Initialize _warnings module before importing the first module.
81 Fix a crash if an empty directory called "encodings" exists in sys.path.
82
Victor Stinner9ca9c252010-05-19 16:53:30 +000083- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
84 encoding and surrogateespace error handler instead of the locale encoding to
85 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
86
Victor Stinner372ac5e2010-05-17 01:26:01 +000087- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
88 (instead of strict) error handler to escape surrogates
89
Victor Stinnerae6265f2010-05-15 16:27:27 +000090- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
91 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000092 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
93 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000094
Victor Stinner59e62db2010-05-15 13:14:32 +000095- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
96 error handler, not only the default error handler (strict)
97
Victor Stinnerb744ba12010-05-15 12:27:16 +000098- Issue #8610: Load file system codec at startup, and display a fatal error on
99 failure. Set the file system encoding to utf-8 (instead of None) if getting
100 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
101
Victor Stinner0964ee12010-04-30 16:48:45 +0000102- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
103 PyUnicode_FromString() to support surrogates in the filename and use the
104 right encoding
105
Georg Brandl8569e582010-05-19 20:57:08 +0000106- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
107
Victor Stinnerb9a20ad2010-04-30 16:37:52 +0000108- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
109
Benjamin Petersonfb886362010-04-24 18:21:17 +0000110- Issue #8419: Prevent the dict constructor from accepting non-string keyword
111 arguments.
112
Victor Stinner14284c22010-04-23 12:02:30 +0000113- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
114 indirectly Python signal handlers anymore because mywrite() ignores
115 exceptions (KeyboardInterrupt)
116
Victor Stinner31be90b2010-04-22 19:38:16 +0000117- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
118 unicode string (eg. backslashreplace)
119
Victor Stinnerdcb24032010-04-22 12:08:36 +0000120- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
121 you have to convert your bytearray filenames to bytes
122
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +0000123- Issue #7332: Remove the 16KB stack-based buffer in
124 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
125 benefit compared to the dynamic memory allocation fallback. Patch by
126 Charles-François Natali.
127
Benjamin Peterson8380dd52010-04-16 22:51:37 +0000128- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
129 passed to bytes or bytearray.
130
Philip Jenvey0805ca32010-04-07 04:04:10 +0000131- Issue #7301: Add environment variable $PYTHONWARNINGS.
132
Benjamin Petersond856ab62010-04-06 21:55:16 +0000133- Issue #8329: Don't return the same lists from select.select when no fds are
134 changed.
135
Mark Dickinson3318d292010-04-06 16:53:17 +0000136- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
137 on 64-bit machines. The shift count for either left or right shift is
138 permitted to be up to sys.maxsize.
139
Benjamin Peterson8daa49e2010-04-03 22:55:48 +0000140- Ensure that tokenization of identifiers is not affected by locale.

Marc-André Lemburg177ab082010-05-05 13:32:59 +0000146- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, in
147 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +0000148
Victor Stinner120c2122010-03-25 00:30:28 +0000149- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
150 is unknown
151

153
Mark Dickinsond59b4162010-03-13 11:34:40 +0000154- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
155 PyMemberDefs could produce an internal error; raise TypeError instead.
156
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000157- Issue #7845: Rich comparison methods on the complex type now return
158 NotImplemented rather than raising a TypeError when comparing with an
159 incompatible type; this allows user-defined classes to implement their own
160 comparisons with complex.
161
Victor Stinner52f6dd72010-03-12 14:45:56 +0000162- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
163 (SIGINT). If an error occurs while importing the site module, the error is
164 printed and Python exits. Initialize the GIL before importing the site
165 module.
166
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000167- Issue #7173: Generator finalization could invalidate sys.exc_info().

170 a fatal error in low memory condition.
171
Victor Stinner6aa278e2010-03-03 00:18:49 +0000172- Issue #7820: The parser tokenizer restores all bytes in the right if
173 the BOM check fails.
174
Benjamin Peterson23e018a2010-02-27 17:40:01 +0000175- Handle errors from looking up __prepare__ correctly.
176
Larry Hastings1373a072010-02-24 22:49:58 +0000177- Issue #5939: Add additional runtime checking to ensure a valid capsule
178 in Modules/_ctypes/callproc.c.
179
Eric Smith0facd772010-02-24 15:42:29 +0000180- Issue #7309: Fix unchecked attribute access when converting
181 UnicodeEncodeError, UnicodeDecodeError, and UnicodeTranslateError to
182 strings.
183

191 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
192 and PyOS_string_to_double instead. See issue #5835 for the original
193 deprecations.
194
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000195- Issue #7385: Fix a crash in `MemoryView_FromObject` when
196 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
197
Mark Dickinsonbc099642010-01-29 17:27:24 +0000198- Issue #7788: Fix an interpreter crash produced by deleting a list
199 slice with very large step value.
200
Eric Smithf7bb5782010-01-27 00:44:57 +0000201- Issue #7766: Change sys.getwindowsversion() return value to a named
202 tuple and add the additional members returned in an OSVERSIONINFOEX
203 structure. The new members are service_pack_major, service_pack_minor,
204 suite_mask, and product_type.
205
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000206- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
207 could crash in many places because of the PyByteArray_AS_STRING() macro
208 returning NULL. The macro now returns a statically allocated empty
209 string instead.
210
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000211- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
212 where the right hand operand is a set of constants, by turning the set into
213 a frozenset and pre-building it as a constant. The comparison operation
214 is made against the constant instead of building a new set each time it is
215 executed (a similar optimization already existed which turned a list of
216 constants into a pre-built tuple). Patch and additional tests by Dave
217 Malcolm.
218
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000219- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
220 methods of bytes, bytearray and unicode objects by using a common
221 implementation based on stringlib's fast search. Patch by Florent Xicluna.
222

224 alpha 2, including: (1) a serious 'wrong output' bug that could
225 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
226 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000227 strings corresponding to subnormal values, (3) a memory leak for
228 some values large enough to cause overflow, and (4) a number of
229 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000230
Benjamin Petersonaea44282010-01-04 01:10:28 +0000231- The __complex__ method is now looked up on the class of instances to make it
232 consistent with other special methods.

236
Benjamin Petersond12362a2009-12-30 19:44:54 +0000237- Issue #7604: Deleting an unset slotted attribute did not raise an
238 AttributeError.
239
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000240- Issue #7534: Fix handling of IEEE specials (infinities, nans,
241 negative zero) in ** operator. The behaviour now conforms to that
242 described in C99 Annex F.
243
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000244- Issue #1811: improve accuracy and cross-platform consistency for
245 true division of integers: the result of a/b is now correctly
246 rounded for ints a and b (at least on IEEE 754 platforms), and in
247 particular does not depend on the internal representation of an int.
248
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000249- Issue #6834: replace the implementation for the 'python' and 'pythonw'
250 executables on OSX.
251
252 These executables now work properly with the arch(1) command:
253 ``arch -ppc python`` will start a universal binary version of python
254 in PPC mode (unlike previous releases).
255
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000256- Issue #7466: segmentation fault when the garbage collector is called
257 in the middle of populating a tuple. Patch by Florent Xicluna.

271 implement the relevant rich comparison methods.
272
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000273- Issue #7298: fixes for range and reversed(range(...)). Iteration
274 over range(a, b, c) incorrectly gave an empty iterator when a, b and
275 c fit in C long but the length of the range did not. Also fix
276 several cases where reversed(range(a, b, c)) gave wrong results, and
277 fix a refleak for reversed(range(a, b, c)) with large arguments.
278
Raymond Hettingerfc438512009-11-01 20:55:33 +0000279- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitrouf978fac2010-05-21 17:25:34 +0000389- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
390 embedders of the interpreter to set sys.argv without also modifying
391 sys.path. This helps fix `CVE-2008-5983
392 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
393

408 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
409 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
410 DeprecationWarning for float arguments passed with the 'L' format
411 code. This will become a TypeError in a future version of Python,
412 to match the behaviour of the other integer format codes.
413

423 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
424 should used for accessing the d_type and d_name members of structures
425 using PyDescr_COMMON.

Mark Dickinson08ade6f2010-06-11 10:44:52 +0000463 now permitted, returning a result based on the exact numerical
464 values of the operands. This builds on issue #2531, which allowed
465 Decimal-to-float comparisons; all comparisons involving numeric
466 types (bool, int, float, complex, Decimal, Fraction) should now
467 act as expected.

608 close() several times is supported. Patch by Pascal Chambon.
609
Antoine Pitrou6e20a1b2010-05-02 19:59:47 +0000610- Issue #4687: Fix accuracy of garbage collection runtimes displayed with
611 gc.DEBUG_STATS.
612
Jean-Paul Calderone6f137ca2010-05-09 03:18:57 +0000613- Issue #8354: The siginterrupt setting is now preserved for all signals,
614 not just SIGCHLD.
615
Georg Brandl25106ce2010-05-21 21:49:47 +0000616- Issue #7192: webbrowser.get("firefox") now works on Mac OS X, as does
Ronald Oussoren4d39f6e2010-05-02 09:54:35 +0000617 webbrowser.get("safari").
618
Lars Gustäbeld6eb70b2010-04-29 15:37:02 +0000619- Issue #8464: tarfile no longer creates files with execute permissions set
620 when mode="w|" is used.
621
Antoine Pitroubf043492010-04-29 10:11:46 +0000622- Issue #7834: Fix connect() of Bluetooth L2CAP sockets with recent versions
623 of the Linux kernel. Patch by Yaniv Aknin.
624
Tarek Ziadé6ac91722010-04-28 17:51:36 +0000625- Issue #8295: Added shutil.unpack_archive.
626
Senthil Kumaran71fb6c82010-04-28 17:39:48 +0000627- Issue #6312: Fixed http HEAD request when the transfer encoding is chunked.
628 It should correctly return an empty response now.
629
Benjamin Peterson95e392c2010-04-27 21:07:21 +0000630- Issue #8546: Reject None given as the buffering argument to _pyio.open.
631
Antoine Pitrou06e34a92010-04-27 19:14:15 +0000632- Issue #8549: Fix compiling the _ssl extension under AIX. Patch by
633 Sridhar Ratnakumar.
634
R. David Murrayad78d152010-04-27 02:45:53 +0000635- Issue #6656: fix locale.format_string to handle escaped percents
636 and mappings.
637
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000638- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
639 where the method could block indefinitely if called just before the
640 event loop started running. This also fixes the occasional freezes
641 witnessed in test_httpservers.
642
Antoine Pitrou40f08742010-04-24 22:04:40 +0000643- Issue #8524: When creating an SSL socket, the timeout value of the
644 original socket wasn't retained (instead, a socket with a positive timeout
645 would be turned into a non-blocking SSL socket).
646
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000647- Issue #5103: SSL handshake would ignore the socket timeout and block
648 indefinitely if the other end didn't respond.
649
650- The do_handshake() method of SSL objects now adjusts the blocking mode of
651 the SSL structure if necessary (as other methods already do).
652
Victor Stinner13bb71c2010-04-23 21:41:56 +0000653- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates
654 and bytes strings for environment keys and values
655
Victor Stinner4d078042010-04-23 19:28:32 +0000656- Issue #8467: Pure Python implementation of subprocess encodes the error
657 message using surrogatepass error handler to support surrogates in the
658 message
659

661
Sean Reifscheider13daf122010-04-23 09:29:52 +0000662- Issue #8451: Syslog module now uses basename(sys.argv[0]) instead of
663 the string "python" as the *ident*. openlog() arguments are all optional
664 and keywords.
665
Antoine Pitrou2c4f98b2010-04-23 00:16:21 +0000666- Issue #8108: Fix the unwrap() method of SSL objects when the socket has
667 a non-infinite timeout. Also make that method friendlier with applications
668 wanting to continue using the socket in clear-text mode, by disabling
669 OpenSSL's internal readahead. Thanks to Darryl Miles for guidance.
670
Antoine Pitrou7062db82010-04-22 13:30:10 +0000671- Issue #8496: make mailcap.lookup() always return a list, rather than an
672 iterator. Patch by Gregory Nofi.
673
Victor Stinner35466c52010-04-22 11:23:23 +0000674- Issue #8195: Fix a crash in sqlite Connection.create_collation() if the
675 collation name contains a surrogate character.
676
Antoine Pitroufec12ff2010-04-21 19:46:23 +0000677- Issue #8484: Load all ciphers and digest algorithms when initializing
678 the _ssl extension, such that verification of some SSL certificates
679 doesn't fail because of an "unknown algorithm".
680
Tarek Ziadéfb437512010-04-20 08:57:33 +0000681- Issue #6547: Added the ignore_dangling_symlinks option to shutil.copytree.
682
Victor Stinnere125f132010-05-15 21:04:43 +0000683- Issue #1540112: Now allowing the choice of a copy function in
Tarek Ziadé5340db32010-04-19 22:30:51 +0000684 shutil.copytree.
685
Giampaolo Rodolà5fb313b2010-04-19 22:05:54 +0000686- Issue #4814: timeout parameter is now applied also for connections resulting
687 from PORT/EPRT commands.
688
Tarek Ziadé10a51af2010-04-19 21:31:42 +0000689- Issue #8463: added missing reference to bztar in shutil's documentation.
690
Ronald Oussoren84151202010-04-18 20:46:11 +0000691- Issue #7154: urllib.request can now detect the proxy settings on OSX 10.6
692 (as long as the user didn't specify 'automatic proxy configuration').
693
Giampaolo Rodolàceb513a2010-04-18 13:36:35 +0000694- Issue #3817: ftplib.FTP.abort() method now considers 225 a valid response
695 code as stated in RFC-959 at chapter 5.4.
696
Victor Stinner738446f02010-04-18 00:00:44 +0000697- Issue #8394: _ctypes.dlopen() accepts bytes, bytearray and str with
698 surrogates.
699
Antoine Pitrou0454af92010-04-17 23:51:58 +0000700- Issue #850728: Add a *timeout* parameter to the `acquire()` method of
Antoine Pitroua7ecfe72010-04-17 23:52:21 +0000701 `threading.Semaphore` objects. Original patch by Torsten Landschoff.
Antoine Pitrou0454af92010-04-17 23:51:58 +0000702
Antoine Pitrou2d9cb9c2010-04-17 17:40:45 +0000703- Issue #8322: Add a *ciphers* argument to SSL sockets, so as to change the
704 available cipher list. Helps fix test_ssl with OpenSSL 1.0.0.
705
Victor Stinner0e59cc32010-04-16 23:49:32 +0000706- Issue #8393: subprocess accepts bytes, bytearray and str with surrogates for
707 the current working directory.
708
Victor Stinner5bfe1462010-04-16 13:28:05 +0000709- Issue #7606: XML-RPC traceback stored in X-traceback is now encoded to ASCII
710 using backslashreplace error handler

717
R. David Murrayd48739f2010-04-14 18:59:18 +0000718- Issue #5277: Fix quote counting when parsing RFC 2231 encoded parameters.
719
Antoine Pitrou7c3e5772010-04-14 15:44:10 +0000720- Issue #7316: the acquire() method of lock objects in the :mod:`threading`
721 module now takes an optional timeout argument in seconds. Timeout support
722 relies on the system threading library, so as to avoid a semi-busy wait
723 loop.
724
Victor Stinner485fb562010-04-13 11:07:24 +0000725- Issue #8383: pickle and pickletools use surrogatepass error handler when
726 encoding unicode as utf8 to support lone surrogates and stay compatible with
727 Python 2.x and 3.0
728
R. David Murrayb2416e52010-04-12 16:58:02 +0000729- Issue #7585: difflib context and unified diffs now place a tab between
730 filename and date, conforming to the 'standards' they were originally
731 designed to follow. This improves compatibility with patch tools.
732
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000733- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
734 character sets will now consistently use a Content-Transfer-Encoding of
735 7bit rather than sometimes being marked as 8bit.
736
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000737- Issue #8375: test_distutils now checks if the temporary directory are still
738 present before it cleans them.
739
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000740- Issue #8374: Update the internal alias table in the :mod:`locale` module
741 to cover recent locale changes and additions.
742
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000743- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
744 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
745 and `ssl.OPENSSL_VERSION_NUMBER`.
746
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000747- Add functools.total_ordering() and functools.cmp_to_key().
748
Mark Dickinson089b00c2010-04-03 15:51:03 +0000749- Issue #8257: The Decimal construct now accepts a float instance
750 directly, converting that float to a Decimal of equal value:
751
752 >>> Decimal(1.1)
753 Decimal('1.100000000000000088817841970012523233890533447265625')
754
Mark Dickinson98127c32010-04-03 11:18:52 +0000755- Issue #8294: The Fraction constructor now accepts Decimal and float
756 instances directly.
757
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000758- Issue #7279: Comparisons involving a Decimal signaling NaN now
759 signal InvalidOperation instead of returning False. (Comparisons
760 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
761 are now hashable; Decimal signaling NaNs remain unhashable.
762
763- Issue #2531: Comparison operations between floats and Decimal
764 instances now return a result based on the numeric values of the
765 operands; previously they returned an arbitrary result based on
Mark Dickinson08ade6f2010-06-11 10:44:52 +0000766 the relative ordering of id(float) and id(Decimal). See also
Mark Dickinson9b88b912010-06-11 10:46:57 +0000767 issue #8188, which adds Decimal-to-Fraction comparisons.
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000768
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000769- Added a subtract() method to collections.Counter().
770
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000771- Issue #8233: When run as a script, py_compile.py optionally takes a single
772 argument `-` which tells it to read files to compile from stdin. Each line
773 is read on demand and the named file is compiled immediately. (Original
774 patch by Piotr Ożarowski).
775
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000776- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
777 form feed (0x0C) are now considered linebreaks, as specified in Unicode
778 Standard Annex #14. See issue #7643.
779 http://www.unicode.org/reports/tr14/
780
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000781- Comparisons using one of <, <=, >, >= between a complex instance and
782 a Fractions instance now raise TypeError instead of returning
783 True/False. This makes Fraction <=> complex comparisons consistent with
784 int <=> complex, float <=> complex, and complex <=> complex comparisons.
785
Antoine Pitrou39b35432010-03-23 00:25:54 +0000786- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
787 some methods (such as oss_mixer_device.fileno()) were not available.
788 Initial patch by Bertrand Janin.
789
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000790- Issue #8205: Remove the "Modules" directory from sys.path when Python is
791 running from the build directory (POSIX only).
792
Antoine Pitrou910bd512010-03-22 20:11:09 +0000793- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
794 didn't support chflags() (for example ZFS under FreeBSD). The error is
795 now silenced.
796
R. David Murrayca2edce2010-03-22 17:48:48 +0000797- Issue #7860: platform.uname now reports the correct 'machine' type
798 when Python is running in WOW64 mode on 64 bit Windows.
799
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000800- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
801 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
802 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000803
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000804- Issue #4282: Fix the main function of the profile module for a non-ASCII
805 script, open the file in binary mode and not in text mode with the default
806 (utf8) encoding.
807
Florent Xicluna54467e02010-03-21 12:29:50 +0000808- Issue #8179: Fix macpath.realpath() on a non-existing path.
809
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000810- Issue #8024: Update the Unicode database to 5.2.
811
Benjamin Peterson00888932010-03-18 22:37:38 +0000812- Issue #8168: py_compile now handles files with utf-8 BOMS.
813
Benjamin Peterson689a5582010-03-18 22:29:52 +0000814- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
815 detected.
816
Martin v. Löwis4b003072010-03-16 13:19:21 +0000817- Issue #6716/2: Backslash-replace error output in compilall.
818
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000819- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
820 with Tcl/Tk-8.5.
821
Matthias Klosec33b9022010-03-16 00:36:26 +0000822- Issue #8140: extend compileall to compile single files. Add -i option.

Matthias Klose82f60912010-03-15 13:46:04 +0000824- Issue #7356: ctypes.util: Make parsing of ldconfig output independent of
825 the locale.
826
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000827- The internals of the subprocess module on POSIX systems have been replaced
828 by an extension module (_posixsubprocess) so that the fork()+exec() can be
829 done safely without the possibility of deadlock in multithreaded applications.
830
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000831- subprocess.Popen now has restore_signals and start_new_session features.
832 The default of restore_signals=True is a new behavior compared to earlier
833 Python versions. This means that signals such as SIGPIPE are not ignored
834 by default in subprocesses launched by Python (Issue #1652).
835
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000836- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

846 the replacement were all bytes. Patch by Antoine Pitrou.
847
Gerhard Häringf9cee222010-03-05 15:20:03 +0000848- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure

880
Andrew M. Kuchlinge1f9beb2010-02-22 22:16:58 +0000881- Issue #6666: fix bug in trace.py that applied the list of directories
882 to be ignored only to the first file. Noted by Bogdan Opanchuk.
883
Andrew M. Kuchlingfbacb062010-02-22 16:52:52 +0000884- Issue #7597: curses.use_env() can now be called before initscr().
885 Noted by Kan-Ru Chen.

893 bytecode file when it was less then 8 bytes.
894
Mark Dickinson84230a12010-02-18 14:49:50 +0000895- Issue #7633: In the decimal module, Context class methods (with the
896 exception of canonical and is_canonical) now accept instances of int
897 and long wherever a Decimal instance is accepted, and implicitly
898 convert that argument to Decimal. Previously only some arguments
899 were converted.
900
R. David Murray1f449142010-02-11 00:15:05 +0000901- Issue #7835: shelve should no longer produce mysterious warnings during

Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000904- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
905 in XML processing instructions and comments. These raw characters are
906 allowed by the XML specification, and are necessary when outputting e.g.
907 PHP code in a processing instruction. Patch by Neil Muller.

920
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000921- Issue #6939: Fix file I/O objects in the `io` module to keep the original
922 file position when calling `truncate()`. It would previously change the
923 file position to the given argument, which goes against the tradition of
924 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
925
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000926- Issue #7610: Reworked implementation of the internal
927 :class:`zipfile.ZipExtFile` class used to represent files stored inside
928 an archive. The new implementation is significantly faster and can
929 be wrapped in a :class:`io.BufferedReader` object for more speedups.
930 It also solves an issue where interleaved calls to `read()` and
931 `readline()` give wrong results. Patch by Nir Aides.

1014 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
1015 the same as passing no argument.

1095 to execute file paths that refer to source or compiled Python files as well
1096 as zipfiles, directories and other valid sys.path entries that contain a
1097 __main__.py file. This allows applications that run other Python scripts to
1098 support the same flexibility as the CPython command line itself.

Victor Stinnere125f132010-05-15 21:04:43 +00001117 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +00001118 recursive locks as fast as regular non-recursive locks (previously,
1119 they were slower by 10x to 15x).

1139 reading from stdin so that existing input does not confuse it and

1278
Brett Cannon64ef00f2009-07-20 03:19:18 +00001279- importlib.abc.PyLoader did not inherit from importlib.abc.ResourceLoader like

Alexander Belopolskyca94f552010-06-17 18:30:34 +00001328- Issue #6641: The ``datetime.strptime`` method now supports the
1329 ``%z`` directive. When the ``%z`` directive is present in the
1330 format string, an aware ``datetime`` object is returned with
1331 ``tzinfo`` bound to a ``datetime.timezone`` instance constructed
1332 from the parsed offset. If both ``%z`` and ``%Z`` are present, the
1333 data in ``%Z`` field is used for timezone name, but ``%Z`` data
1334 without ``%z`` is discarded.
1335
Alexander Belopolsky4e749a12010-06-14 14:15:50 +00001336- Issue #5094: The ``datetime`` module now has a simple concrete class
1337 implementing ``datetime.tzinfo`` interface. Instances of the new
1338 class, ``datetime.timezone``, return fixed name and UTC offset from
1339 their ``tzname(dt)`` and ``utcoffset(dt)`` methods. The ``dst(dt)``
1340 method always returns ``None``. A class attribute, ``utc`` contains
1341 an instance representing the UTC timezone. Original patch by Rafe
1342 Kaplan.
1343
Mark Dickinson4b80ef52010-06-12 15:17:02 +00001344- Issue #8973: Add __all__ to struct module; this ensures that

1346
Alexander Belopolskyfcdc79a2010-06-12 17:18:45 +00001347- Issue #3129: Trailing digits in struct format string are no longer ignored.

Stefan Kraha3ac44e2010-06-08 14:00:52 +00001351- Issue #7384: If the system readline library is linked against ncurses,
1352 the curses module must be linked against ncurses as well. Otherwise it
1353 is not safe to load both the readline and curses modules in an application.
1354
Brian Curtin60853212010-05-26 17:43:50 +00001355- Issue #2810: Fix cases where the Windows registry API returns

1359 algorithm with an improved 'binary-split' algorithm that uses fewer
1360 multiplications and allows many of the multiplications to be
1361 performed using plain C integer arithmetic instead of PyLong
1362 arithmetic. Also uses a lookup table for small arguments.
1363
Mark Dickinson85eacea2010-05-10 16:27:45 +00001364- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing
1365 overflow checks in the audioop module.
1366
Mark Dickinson0381e3f2010-05-08 14:35:02 +00001367- Issue #8644: The accuracy of td.total_seconds() has been improved (by
1368 calculating with integer arithmetic instead of float arithmetic internally):
1369 the result is now always correctly rounded, and is equivalent to td /
1370 timedelta(seconds=1).
1371
Mark Dickinson7c186e22010-04-20 22:32:49 +00001372- Issue #2706: Allow division of a timedelta by another timedelta:

1379 integer format code, struct.pack first attempts to convert the non-integer
1380 using its __index__ method. If that method is non-existent or raises
1381 TypeError it goes on to try the __int__ method, as described below.
1382
Matthias Klosea8349752010-03-15 13:25:28 +00001383- Issue #8142: Update libffi to the 3.0.9 release.

R. David Murrayba311052009-12-04 00:09:14 +00001602 file in the Lib/test directory, which might be read-only for the
1603 user running the tests.
1604
R. David Murray35768ad2009-11-15 00:23:21 +00001605- Issue #7324: add a sanity check to regrtest argument parsing to

1627 calling methods on the object.
1628
Antoine Pitrou65c9c642009-10-30 17:25:12 +00001629- Issue #7222: Make thread "reaping" more reliable so that reference
1630 leak-chasing test runs give sensible results. The previous method of
1631 reaping threads could return successfully while some Thread objects were
1632 still referenced. This also introduces a new private function:
1633 :func:`_thread._count()`.
1634
R. David Murray27144602009-10-19 15:26:16 +00001635- Issue #7151: fixed regrtest -j so that output to stderr from a test no
1636 longer runs the risk of causing the worker thread to fail.
1637
Antoine Pitrou4de39cd2009-10-10 21:08:31 +00001638- Issue #7055: test___all__ now greedily detects all modules which have an
1639 __all__ attribute, rather than using a hardcoded and incomplete list.

1642 runtest_inner in regrtest, with warnings if the called test modifies them,
1643 and a new section in the summary report at the end.
R. David Murray097e51f2009-10-07 23:38:55 +00001644
Mark Dickinson2e304402009-10-04 18:43:54 +00001645- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.
1646
Brett Cannon3c273842009-07-20 00:14:29 +00001647- Fixed tests in importlib.test.source.test_abc_loader that were masking
1648 the proper exceptions that should be raised for missing or improper code
1649 object bytecode.
1650
Brett Cannonb49c70c2009-07-15 04:08:33 +00001651- Removed importlib's custom test discovery code and switched to

1661 sandbox.

1791
Martin v. Löwis8ed91b22009-05-29 16:22:26 +00001792- Issue #6097: Escape UTF-8 surrogates resulting from mbstocs conversion
1793 of the command line.
1794
Martin v. Löwisc15bdef2009-05-29 14:47:46 +00001795- Issue #6012: Add cleanup support to O& argument parsing.
1796
Eric Smith41669ca2009-05-23 14:23:22 +00001797- Issue #6089: Fixed str.format with certain invalid field specifiers
1798 that would raise SystemError.
1799
Raymond Hettinger2bcde142009-05-29 04:52:27 +00001800- Issue #5982: staticmethod and classmethod now expose the wrapped
1801 function with __func__.
1802
Raymond Hettinger91e3b9d2009-05-28 22:20:03 +00001803- Added support for multiple context managers in the same with-statement.
1804 Deprecated contextlib.nested() which is no longer needed.
Georg Brandl0c315622009-05-25 21:10:36 +00001805
Mark Dickinson6b1e43b2009-05-20 18:41:04 +00001806- Issue #5829: complex("1e500") no longer raises OverflowError. This
1807 makes it consistent with float("1e500") and interpretation of real
1808 and imaginary literals.
1809
Hirokazu Yamamoto8223c242009-05-17 04:21:53 +00001810- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.
1811
R. David Murraydd226ea2009-05-13 12:27:21 +00001812- Issue #5994: the marshal module now has docstrings.
1813
Mark Dickinsond1ec8b22009-05-11 15:45:15 +00001814- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
1815 (1) inf and nan strings with trailing whitespace were incorrectly
1816 rejected; (2) parsing of strings representing infinities and nans
1817 was locale aware; and (3) the interpretation of fromhex('-nan')
1818 didn't match that of float('-nan').
1819
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001820Library
1821-------
1822
Martin v. Löwisb6a748b2009-05-29 15:23:17 +00001823- Issue #4859: Implement PEP 383 for pwd, spwd, and grp.
1824
R. David Murrayfb123912009-05-28 18:19:00 +00001825- smtplib 'login' and 'cram-md5' login are also fixed (see Issue #5259).
1826
R. David Murray1f1b9d32009-05-27 20:56:59 +00001827- Issue #6121: pydoc now ignores leading and trailing spaces in the
1828 argument to the 'help' function.
1829
Georg Brandlfaf41492009-05-26 18:31:11 +00001830- Issue #6118: urllib.parse.quote_plus ignored the encoding and errors
1831 arguments for strings with a space in them.
1832
Raymond Hettinger089ba7f2009-05-27 00:38:24 +00001833- collections.namedtuple() was not working with the following field
1834 names: cls, self, tuple, itemgetter, and property.
1835
Benjamin Peterson14a3dd72009-05-25 00:51:58 +00001836- In unittest, using a skipping decorator on a class is now equivalent to
1837 skipping every test on the class. The ClassTestSuite class has been removed.
1838
Martin v. Löwis70ccd162009-05-24 19:47:22 +00001839- Issue #6050: Don't fail extracting a directory from a zipfile if
1840 the directory already exists.
1841
Antoine Pitrou61f77b52009-05-24 15:46:13 +00001842- Issue #1309352: fcntl now converts its third arguments to a C `long` rather
1843 than an int, which makes some operations possible under 64-bit Linux (e.g.
1844 DN_MULTISHOT with F_NOTIFY).
1845
Antoine Pitrou716c4442009-05-23 19:04:03 +00001846- Issue #5761: Add the name of the underlying file to the repr() of various
1847 IO objects.
1848
R. David Murraycaa27b72009-05-23 18:49:56 +00001849- Issue #5259: smtplib plain auth login no longer gives a traceback. Fix
1850 by Musashi Tamura, tests by Marcin Bachry.
1851
Antoine Pitrouc3ee1662009-05-23 16:02:33 +00001852- Issue #1983: Fix functions taking or returning a process identifier to use
1853 the dedicated C type ``pid_t`` instead of a C ``int``. Some platforms have
1854 a process identifier type wider than the standard C integer type.
1855
R. David Murray87e20742009-05-23 01:30:26 +00001856- Issue #4066: smtplib.SMTP_SSL._get_socket now correctly returns the socket.

1860 deepcopy()ing.
1861

1867
Antoine Pitroue4501852009-05-14 18:55:55 +00001868- Issue #5006: Better handling of unicode byte-order marks (BOM) in the io
1869 library. This means, for example, that opening an UTF-16 text file in
1870 append mode doesn't add a BOM at the end of the file if the file isn't
1871 empty.
1872
R. David Murray74b89242009-05-13 17:33:03 +00001873- Issue #4050: inspect.findsource/getsource now raise an IOError if the 'source'
1874 file is a binary. Patch by Brodie Rao, tests by Daniel Diniz. This fix
1875 corrects a pydoc regression.
1876
R. David Murray99352742009-05-07 18:24:38 +00001877- Issue 5955: aifc's close method did not close the file it wrapped,
1878 now it does. This also means getfp method now returns the real fp.
1879
Benjamin Peterson932073a2009-05-23 16:14:33 +00001880Installation
1881------------
1882
1883- Issue #6047: fullinstall has been removed because Python 3's executable will
1884 now be known as python3.
Benjamin Petersonaccdca52009-05-06 23:26:59 +00001885
Ronald Oussorenbe7149e2009-05-26 21:39:08 +00001886- Lib/smtpd.py is no longer installed as a script.

Benjamin Petersonbd35b032009-04-04 23:16:41 +00001920
1921Core and Builtins
1922-----------------
1923
Mark Dickinson865e01a2009-05-07 16:37:01 +00001924- Issue #5914: Add new C API function PyOS_string_to_double, and
1925 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
1926
Eric Smith741191f2009-05-06 13:08:15 +00001927- Issue #3382: float.__format__, complex.__format__, and %-formatting
1928 no longer map 'F' to 'f'. Because of issue #5859 (below), this only
1929 affects nan -> NAN and inf -> INF.
1930
Mark Hammond5a607a32009-05-06 08:04:54 +00001931- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1932 in all operations, including splitdrive, split, etc. splitunc() now issues
1933 a PendingDeprecation warning.
1934
Eric Smith63376222009-05-05 14:04:18 +00001935- Issue #5920: For float.__format__, change the behavior with the
1936 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1937 to be like 'g' but with at least one decimal point and with a
1938 default precision of 12. Previously, the behavior the same but with
1939 a default precision of 6. This more closely matches str(), and
1940 reduces surprises when adding alignment flags to the empty
1941 presentation type. This also affects the new complex.__format__ in
1942 the same way.
1943
Martin v. Löwis011e8422009-05-05 04:43:17 +00001944- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1945
R. David Murrayb18500d2009-05-04 22:59:07 +00001946- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1947 shadowed by classtype's, even if it was None. property now
1948 inserts the __doc__ into the subclass instance __dict__.
1949
Antoine Pitrou244651a2009-05-04 18:56:13 +00001950- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1951 sequences. Patch by Nick Barnes and Victor Stinner.
1952
Martin v. Löwise0a2b722009-05-10 08:08:56 +00001953- Issue #3672: Reject surrogates in utf-8 codec; add surrogatepass error handler.
Martin v. Löwisdb12d452009-05-02 18:52:14 +00001954
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001955- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1956 received a new method, detach(). detach() disconnects the underlying stream
1957 from the buffer or text IO and returns it.
1958
Mark Dickinson33841c32009-05-01 15:37:04 +00001959- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1960 floats with absolute value over 1e50. Also remove length
1961 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1962 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001963
Eric Smith741191f2009-05-06 13:08:15 +00001964- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001965 format(complex(1, 2./3), '.5') now produces a sensible result.
1966
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001967- Issue #5864: Fix empty format code formatting for floats so that it
1968 never gives more than the requested number of significant digits.
1969
Eric Smith6dc46f52009-04-27 20:39:49 +00001970- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
1971 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
1972
Eric Smithcc32a112009-04-26 21:35:14 +00001973- Issue #5835: Deprecate PyOS_ascii_formatd.
1974
Martin v. Löwis71efeb72009-04-26 01:02:07 +00001975- Issue #4971: Fix titlecase for characters that are their own
1976 titlecase, but not their own uppercase.
1977
Benjamin Peterson193152c2009-04-25 01:08:45 +00001978- Issue #5283: Setting __class__ in __del__ caused a segfault.
1979
Mark Dickinsonad476da2009-04-23 19:14:16 +00001980- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1981 z involves nans, infs or negative zeros.
1982
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001983- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001984
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001985- Issue #1869 (and many duplicates): make round(x, n) correctly
1986 rounded for a float x, by using the decimal <-> binary conversions
1987 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1988 consistently agrees with format(x, '.2f').
1989
Benjamin Petersonae937c02009-04-18 20:54:08 +00001990- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1991 some builtin types.
1992
Eric Smith0923d1d2009-04-16 20:16:10 +00001993- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1994
Eric Smith35e84722009-04-16 20:21:28 +00001995- Issue #5515: str.format() type 'n' combined with commas and leading
1996 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001997
1998- Implement PEP 378, Format Specifier for Thousands Separator, for
1999 floats.
2000
Mark Dickinson3370cce2009-04-17 22:40:53 +00002001- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002002 1e11, not 1e12. This avoids printing 13 significant digits in
2003 situations where only 12 of them are correct. Example problem
2004 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2005 long time.)
2006
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002007- Issue #1580: On most platforms, use a 'short' float repr: for a
2008 finite float x, repr(x) now outputs a string based on the shortest
2009 sequence of decimal digits that rounds to x. Previous behaviour was
2010 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002011 Another minor difference is that the new repr switches to
2012 exponential notation at 1e16 instead of the previous 1e17; this
2013 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002014
2015 There's a new sys attribute sys.float_repr_style, which takes
2016 the value 'short' to indicate that we're using short float repr,
2017 and 'legacy' if the short float repr isn't available for one
2018 reason or another.
2019
2020 The float repr change involves incorporating David Gay's 'perfect
2021 rounding' code into the Python core (it's in Python/dtoa.c). As a
2022 secondary consequence, all string-to-float and float-to-string
2023 conversions (including all float formatting operations) will be
2024 correctly rounded on these platforms.
2025
2026 See issue 1580 discussions for details of platforms for which
2027 this change does not apply.
2028
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002029- Issue #5759: float() didn't call __float__ on str subclasses.
2030
Georg Brandlabc38772009-04-12 15:51:51 +00002031- The string.maketrans() function is deprecated; there is a new static method
2032 maketrans() on the bytes and bytearray classes. This removes confusion about
2033 the types string.maketrans() is supposed to work with, and mirrors the
2034 methods available on the str class.
2035
R. David Murraydc6da8a2009-04-09 22:16:43 +00002036- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
2037 its clarity and its speed.
2038
Matthias Klose091c7b12009-04-07 13:24:27 +00002039- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
2040 to avoid compiler warnings.
2041
Walter Dörwald8dc33d52009-05-06 14:41:26 +00002042- Issue #3739: The unicode-internal encoder now reports the number of characters
2043 consumed like any other encoder (instead of the number of bytes).

Raymond Hettingere8364232009-02-02 22:55:09 +00002342 were suppressing all exceptions. These include list() and bytearray().
2343
Mark Dickinson1124e712009-01-28 21:25:58 +00002344- Issue #4707: round(x, n) now returns an integer if x is an integer.
2345 Previously it returned a float.
2346
Antoine Pitroub52ec782009-01-25 16:34:23 +00002347- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2348 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2349 evaluation loop is compiled with a new dispatch mechanism which gives
2350 speedups of up to 20%, depending on the system, on various benchmarks.
2351
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002352- Issue #4874: Most builtin decoders now reject unicode input.

2358
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002359- Issue #4838: When a module is deallocated, free the memory backing the
2360 optional module state data.
2361
Mark Dickinson8055afd2009-01-17 10:04:45 +00002362- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2363 type to (void *).
2364
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002365- Issue #4935: The overflow checking code in the expandtabs() method common
2366 to str, bytes and bytearray could be optimized away by the compiler, letting
2367 the interpreter segfault instead of raising an error.
2368
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002369- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2370 __next__ method.
2371
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002372- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2373 function no longer attempt to call the __long__ slot to convert an object
2374 to an integer. Only the __int__ and __trunc__ slots are examined.
2375
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002376- Issue #4893: Use NT threading on CE.

2379
Antoine Pitrouab868312009-01-10 15:40:25 +00002380- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2381 common cases are optimized thanks to a dedicated fast path and a moderate
2382 amount of loop unrolling.
2383
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002384- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2385 collecting the oldest generation) so that allocating lots of objects without
2386 destroying them does not show quadratic performance. Based on a proposal by
2387 Martin von Löwis at
2388 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2389
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002390- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002391 having been closed (for instance, a read() call could return some
2392 previously buffered data). Patch by Dmitry Vasiliev.
2393
Antoine Pitrou05608432009-01-09 18:53:14 +00002394- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2395 flag to work properly. Furthermore, when specifying -u, the text stdout
2396 and stderr streams have line-by-line buffering enabled (the default being
2397 to buffer arbitrary chunks of data).
2398
Raymond Hettinger35631532009-01-09 03:58:09 +00002399- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2400 instead of ints (reducing its size from 4 to 8 times thereby reducing
2401 Python's overall memory).
2402
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002403- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2404 an existing .py counterpart, override the co_filename attributes of all
2405 code objects if the original filename is obsolete (which can happen if the
2406 file has been renamed, moved, or if it is accessed through different paths).
2407 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2408
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002409- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2410 one byte. Also fixes the meaning of len() so that it returns the number of
2411 items, rather than the size in bytes.
2412
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002413- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2414
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002415- Issue #4747: When the terminal does not use utf-8, executing a script with
2416 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2417
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002418- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002419 file with `bytes' filename on Windows.

Antoine Pitrou7ddda782009-01-01 15:35:33 +00002421- Issue #3680: Reference cycles created through a dict, set or deque iterator
2422 did not get collected.
2423
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002424- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2425 where the tp_hash and tp_dict slots are both NULL.
2426
Georg Brandlccc47b62008-12-28 11:44:14 +00002427- Issue #4759: None is now allowed as the first argument of
2428 bytearray.translate(). It was always allowed for bytes.translate().
2429
Skip Montanaro80072cb2008-12-23 03:51:14 +00002430- Added test case to ensure attempts to read from a file opened for writing
2431 fail.
2432
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002433- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002435- Issue #2183: Simplify and optimize bytecode for list, dict and set
2436 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2437
Antoine Pitrou621601a2008-12-17 23:18:19 +00002438- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2439 print elapsed times, not only when some objects are uncollectable /
2440 unreachable. Original patch by Neil Schemenauer.
2441
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002442- Issue #3439: Add a bit_length method to int.
2443
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002444- Issue #2173: When getting device encoding, check that return value of
2445 nl_langinfo is not the empty string. This was causing silent build
2446 failures on OS X.
2447
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002448- Issue #4597: Fixed several opcodes that weren't always propagating
2449 exceptions.
2450
2451- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002452 context manager returns a value that cannot be converted to a bool.
2453
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002454- Issue #4445: Replace "sizeof(PyBytesObject)" with
2455 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2456 bytes instances. On a typical machine this saves 3 bytes of memory
2457 (on average) per allocation of a bytes instance.
2458
Christian Heimesa872de52008-12-05 08:26:55 +00002459- Issue #4533: File read operation was dreadfully slow due to a slowly
2460 growing read buffer. Fixed by using the same growth rate algorithm as
2461 Python 2.x.
2462
Antoine Pitrou5504e892008-12-06 21:27:53 +00002463- Issue #4509: Various issues surrounding resize of bytearray objects to
2464 which there are buffer exports (e.g. memoryview instances).
2465
Georg Brandlf9734072008-12-07 15:30:06 +00002466- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2467 method on file objects with closefd=False. The file descriptor is still
2468 kept open but the file object behaves like a closed file. The ``FileIO``
2469 object also got a new readonly attribute ``closefd``.

Antoine Pitroubc420402008-12-07 20:14:49 +00002471- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2472 larger than 1.

2477
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002478- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2479 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2480 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2481 of using the replace error handler in PyUnicode_DecodeUTF8().
