12Core and Builtins
13-----------------
14
Mark Dickinsoncc6a9822010-05-21 14:55:26 +000015- Issue #8748: Fix two issues with comparisons between complex and integer
16 objects. (1) The comparison could incorrectly return True in some cases
17 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
18 (2) The comparison raised an OverflowError for large integers, leading
19 to unpredictable exceptions when combining integers and complex objects
20 in sets or dicts.
21
22- Issue #8748: Fix comparisons between complex and integer objects.
23 These used to convert the integer object to a complex number before
24 doing the comparison, giving a potentially incorrect result when
25 that conversion involved precision loss. (Ex: 2**53+1 ==
26 complex(2**53) returned True; now returns False.)
27
Victor Stinner7d79b8b2010-05-19 20:40:50 +000028- Issue #8766: Initialize _warnings module before importing the first module.
29 Fix a crash if an empty directory called "encodings" exists in sys.path.
30
Victor Stinner9ca9c252010-05-19 16:53:30 +000031- Issue #8589: Decode PYTHONWARNINGS environment variable with the file system
32 encoding and surrogateespace error handler instead of the locale encoding to
33 be consistent with os.environ. Add PySys_AddWarnOptionUnicode() function.
34
Victor Stinner372ac5e2010-05-17 01:26:01 +000035- PyObject_Dump() encodes unicode objects to utf8 with backslashreplace
36 (instead of strict) error handler to escape surrogates
37
Victor Stinnerae6265f2010-05-15 16:27:27 +000038- Issue #8715: Create PyUnicode_EncodeFSDefault() function: Encode a Unicode
39 object to Py_FileSystemDefaultEncoding with the "surrogateescape" error
Benjamin Peterson0c3d21d2010-05-15 17:43:57 +000040 handler, and return bytes. If Py_FileSystemDefaultEncoding is not set, fall
41 back to UTF-8.
Victor Stinnerae6265f2010-05-15 16:27:27 +000042
Victor Stinner59e62db2010-05-15 13:14:32 +000043- Enable shortcuts for common encodings in PyUnicode_AsEncodedString() for any
44 error handler, not only the default error handler (strict)
45
Victor Stinnerb744ba12010-05-15 12:27:16 +000046- Issue #8610: Load file system codec at startup, and display a fatal error on
47 failure. Set the file system encoding to utf-8 (instead of None) if getting
48 the locale encoding failed, or if nl_langinfo(CODESET) function is missing.
49
Victor Stinner0964ee12010-04-30 16:48:45 +000050- PyFile_FromFd() uses PyUnicode_DecodeFSDefault() instead of
51 PyUnicode_FromString() to support surrogates in the filename and use the
52 right encoding
53
Georg Brandl8569e582010-05-19 20:57:08 +000054- Issue #7507: Quote "!" in pipes.quote(); it is special to some shells.
55
Victor Stinnerb9a20ad2010-04-30 16:37:52 +000056- PyUnicode_DecodeFSDefaultAndSize() uses surrogateescape error handler
57
Benjamin Petersonfb886362010-04-24 18:21:17 +000058- Issue #8419: Prevent the dict constructor from accepting non-string keyword
59 arguments.
60
Victor Stinner14284c22010-04-23 12:02:30 +000061- Issue #8124: PySys_WriteStdout() and PySys_WriteStderr() don't execute
62 indirectly Python signal handlers anymore because mywrite() ignores
63 exceptions (KeyboardInterrupt)
64
Victor Stinner31be90b2010-04-22 19:38:16 +000065- Issue #8092: Fix PyUnicode_EncodeUTF8() to support error handler producing
66 unicode string (eg. backslashreplace)
67
Victor Stinnerdcb24032010-04-22 12:08:36 +000068- Issue #8485: PyUnicode_FSConverter() doesn't accept bytearray object anymore,
69 you have to convert your bytearray filenames to bytes
70
Antoine Pitrou5bc7ec92010-04-21 22:56:22 +000071- Issue #7332: Remove the 16KB stack-based buffer in
72 PyMarshal_ReadLastObjectFromFile, which doesn't bring any noticeable
73 benefit compared to the dynamic memory allocation fallback. Patch by
74 Charles-François Natali.
75
Benjamin Peterson8380dd52010-04-16 22:51:37 +000076- Issue #8417: Raise an OverflowError when an integer larger than sys.maxsize is
77 passed to bytes or bytearray.
78
Philip Jenvey0805ca32010-04-07 04:04:10 +000079- Issue #7301: Add environment variable $PYTHONWARNINGS.
80
Benjamin Petersond856ab62010-04-06 21:55:16 +000081- Issue #8329: Don't return the same lists from select.select when no fds are
82 changed.
83
Mark Dickinson3318d292010-04-06 16:53:17 +000084- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
85 on 64-bit machines. The shift count for either left or right shift is
86 permitted to be up to sys.maxsize.
87
Benjamin Peterson8daa49e2010-04-03 22:55:48 +000088- Ensure that tokenization of identifiers is not affected by locale.

95 case it is set.
Victor Stinner00d6a1d2010-03-25 01:02:29 +000096
Victor Stinner120c2122010-03-25 00:30:28 +000097- Issue #8226: sys.setfilesystemencoding() raises a LookupError if the encoding
98 is unknown
99
Victor Stinner808fc0a2010-03-22 12:50:40 +0000100- Issue #1583863: An str subclass can now override the __str__ method
101
Mark Dickinsond59b4162010-03-13 11:34:40 +0000102- Issue #8014: Setting a T_UINT or T_PYSSIZET attribute of an object with
103 PyMemberDefs could produce an internal error; raise TypeError instead.
104
Mark Dickinsonf673f0c2010-03-13 09:48:39 +0000105- Issue #7845: Rich comparison methods on the complex type now return
106 NotImplemented rather than raising a TypeError when comparing with an
107 incompatible type; this allows user-defined classes to implement their own
108 comparisons with complex.
109
Victor Stinner52f6dd72010-03-12 14:45:56 +0000110- Issue #3137: Don't ignore errors at startup, especially a keyboard interrupt
111 (SIGINT). If an error occurs while importing the site module, the error is
112 printed and Python exits. Initialize the GIL before importing the site
113 module.
114
Benjamin Petersonae5f2f42010-03-07 17:10:51 +0000115- Issue #7173: Generator finalization could invalidate sys.exc_info().

139 PyOS_ascii_strtod, and PyOS_ascii_atof. Use PyOS_double_to_string
140 and PyOS_string_to_double instead. See issue #5835 for the original
141 deprecations.
142
Antoine Pitrou05b7c562010-02-02 22:47:00 +0000143- Issue #7385: Fix a crash in `MemoryView_FromObject` when
144 `PyObject_GetBuffer` fails. Patch by Florent Xicluna.
145
Mark Dickinsonbc099642010-01-29 17:27:24 +0000146- Issue #7788: Fix an interpreter crash produced by deleting a list
147 slice with very large step value.
148
Eric Smithf7bb5782010-01-27 00:44:57 +0000149- Issue #7766: Change sys.getwindowsversion() return value to a named
150 tuple and add the additional members returned in an OSVERSIONINFOEX
151 structure. The new members are service_pack_major, service_pack_minor,
152 suite_mask, and product_type.
153
Antoine Pitroufc8d6f42010-01-17 12:38:54 +0000154- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
155 could crash in many places because of the PyByteArray_AS_STRING() macro
156 returning NULL. The macro now returns a statically allocated empty
157 string instead.
158
Antoine Pitroub7fbcd32010-01-16 18:37:38 +0000159- Issue #6690: Optimize the bytecode for expressions such as `x in {1, 2, 3}`,
160 where the right hand operand is a set of constants, by turning the set into
161 a frozenset and pre-building it as a constant. The comparison operation
162 is made against the constant instead of building a new set each time it is
163 executed (a similar optimization already existed which turned a list of
164 constants into a pre-built tuple). Patch and additional tests by Dave
165 Malcolm.
166
Antoine Pitrouf2c54842010-01-13 08:07:53 +0000167- Issue #7622: Improve the split(), rsplit(), splitlines() and replace()
168 methods of bytes, bytearray and unicode objects by using a common
169 implementation based on stringlib's fast search. Patch by Florent Xicluna.
170
Mark Dickinson45b63652010-01-16 18:10:25 +0000171- Issue #7632: Fix various str -> float conversion bugs present in 2.7
172 alpha 2, including: (1) a serious 'wrong output' bug that could
173 occur for long (> 40 digit) input strings, (2) a crash in dtoa.c
174 that occurred in debug builds when parsing certain long numeric
Mark Dickinsonc4f18682010-01-17 14:39:12 +0000175 strings corresponding to subnormal values, (3) a memory leak for
176 some values large enough to cause overflow, and (4) a number of
177 flaws that could lead to incorrectly rounded results.
Mark Dickinson81612e82010-01-12 23:04:19 +0000178
Benjamin Petersonaea44282010-01-04 01:10:28 +0000179- The __complex__ method is now looked up on the class of instances to make it
180 consistent with other special methods.
181

183 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
184
Benjamin Petersond12362a2009-12-30 19:44:54 +0000185- Issue #7604: Deleting an unset slotted attribute did not raise an
186 AttributeError.
187
Mark Dickinson9ab44b52009-12-30 16:22:49 +0000188- Issue #7534: Fix handling of IEEE specials (infinities, nans,
189 negative zero) in ** operator. The behaviour now conforms to that
190 described in C99 Annex F.
191
Mark Dickinsoncbb62742009-12-27 15:09:50 +0000192- Issue #1811: improve accuracy and cross-platform consistency for
193 true division of integers: the result of a/b is now correctly
194 rounded for ints a and b (at least on IEEE 754 platforms), and in
195 particular does not depend on the internal representation of an int.
196
Ronald Oussoren6f6c5622009-12-24 14:03:19 +0000197- Issue #6834: replace the implementation for the 'python' and 'pythonw'
198 executables on OSX.
199
200 These executables now work properly with the arch(1) command:
201 ``arch -ppc python`` will start a universal binary version of python
202 in PPC mode (unlike previous releases).
203
Antoine Pitrou6b7dfc92009-12-12 19:18:27 +0000204- Issue #7466: segmentation fault when the garbage collector is called
205 in the middle of populating a tuple. Patch by Florent Xicluna.

220
Mark Dickinsond550c9a2009-11-15 09:57:26 +0000221- Issue #7298: fixes for range and reversed(range(...)). Iteration
222 over range(a, b, c) incorrectly gave an empty iterator when a, b and
223 c fit in C long but the length of the range did not. Also fix
224 several cases where reversed(range(a, b, c)) gave wrong results, and
225 fix a refleak for reversed(range(a, b, c)) with large arguments.
226
Raymond Hettingerfc438512009-11-01 20:55:33 +0000227- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Antoine Pitrouf978fac2010-05-21 17:25:34 +0000337- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows
338 embedders of the interpreter to set sys.argv without also modifying
339 sys.path. This helps fix `CVE-2008-5983
340 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-5983>`_.
341

356 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
357 PyArg_VaParseTupleAndKeywords and PyArg_Parse now raise a
358 DeprecationWarning for float arguments passed with the 'L' format
359 code. This will become a TypeError in a future version of Python,
360 to match the behaviour of the other integer format codes.
361

371 in PEP 3123). The PyDescr_TYPE and PyDescr_NAME macros should be
372 should used for accessing the d_type and d_name members of structures
373 using PyDescr_COMMON.
374
375- Issue #6405: Remove duplicate type declarations in descrobject.h.

481
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000482- Issue #8567: Fix precedence of signals in Decimal module: when a
483 Decimal operation raises multiple signals and more than one of those
484 signals is trapped, the specification determines the order in which
485 the signals should be handled. In many cases this order wasn't
486 being followed, leading to the wrong Python exception being raised.

519
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000520- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
521 where the method could block indefinitely if called just before the
522 event loop started running. This also fixes the occasional freezes
523 witnessed in test_httpservers.
524
Antoine Pitrou40f08742010-04-24 22:04:40 +0000525- Issue #8524: When creating an SSL socket, the timeout value of the
526 original socket wasn't retained (instead, a socket with a positive timeout
527 would be turned into a non-blocking SSL socket).
528
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000529- Issue #5103: SSL handshake would ignore the socket timeout and block
530 indefinitely if the other end didn't respond.
531
532- The do_handshake() method of SSL objects now adjusts the blocking mode of
533 the SSL structure if necessary (as other methods already do).
534
Victor Stinner13bb71c2010-04-23 21:41:56 +0000535- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

R. David Murrayb2416e52010-04-12 16:58:02 +0000611- Issue #7585: difflib context and unified diffs now place a tab between
612 filename and date, conforming to the 'standards' they were originally
613 designed to follow. This improves compatibility with patch tools.
614
R. David Murrayef3d6bd2010-04-12 14:48:58 +0000615- Issue #7472: Fixed typo in email.encoders module; messages using ISO-2022
616 character sets will now consistently use a Content-Transfer-Encoding of
617 7bit rather than sometimes being marked as 8bit.
618
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000619- Issue #8375: test_distutils now checks if the temporary directory are still
620 present before it cleans them.
621
Antoine Pitrou0c70d2d2010-04-11 22:35:34 +0000622- Issue #8374: Update the internal alias table in the :mod:`locale` module
623 to cover recent locale changes and additions.
624
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000625- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
626 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
627 and `ssl.OPENSSL_VERSION_NUMBER`.
628
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000629- Add functools.total_ordering() and functools.cmp_to_key().
630
Mark Dickinson089b00c2010-04-03 15:51:03 +0000631- Issue #8257: The Decimal construct now accepts a float instance
632 directly, converting that float to a Decimal of equal value:
633
634 >>> Decimal(1.1)
635 Decimal('1.100000000000000088817841970012523233890533447265625')
636
Mark Dickinson98127c32010-04-03 11:18:52 +0000637- Issue #8294: The Fraction constructor now accepts Decimal and float
638 instances directly.
639
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000640- Issue #7279: Comparisons involving a Decimal signaling NaN now
641 signal InvalidOperation instead of returning False. (Comparisons
642 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
643 are now hashable; Decimal signaling NaNs remain unhashable.
644
645- Issue #2531: Comparison operations between floats and Decimal
646 instances now return a result based on the numeric values of the
647 operands; previously they returned an arbitrary result based on
648 the relative ordering of id(float) and id(Decimal).
649
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000650- Added a subtract() method to collections.Counter().
651
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000652- Issue #8233: When run as a script, py_compile.py optionally takes a single
653 argument `-` which tells it to read files to compile from stdin. Each line
654 is read on demand and the named file is compiled immediately. (Original
655 patch by Piotr Ożarowski).
656
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000657- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
658 form feed (0x0C) are now considered linebreaks, as specified in Unicode
659 Standard Annex #14. See issue #7643.
660 http://www.unicode.org/reports/tr14/
661
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000662- Comparisons using one of <, <=, >, >= between a complex instance and
663 a Fractions instance now raise TypeError instead of returning
664 True/False. This makes Fraction <=> complex comparisons consistent with
665 int <=> complex, float <=> complex, and complex <=> complex comparisons.
666
Antoine Pitrou39b35432010-03-23 00:25:54 +0000667- Issue #8139: ossaudiodev didn't initialize its types properly, therefore
668 some methods (such as oss_mixer_device.fileno()) were not available.
669 Initial patch by Bertrand Janin.
670
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000671- Issue #8205: Remove the "Modules" directory from sys.path when Python is
672 running from the build directory (POSIX only).
673
Antoine Pitrou910bd512010-03-22 20:11:09 +0000674- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
675 didn't support chflags() (for example ZFS under FreeBSD). The error is
676 now silenced.
677
R. David Murrayca2edce2010-03-22 17:48:48 +0000678- Issue #7860: platform.uname now reports the correct 'machine' type
679 when Python is running in WOW64 mode on 64 bit Windows.
680
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000681- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
682 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
683 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000684
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000685- Issue #4282: Fix the main function of the profile module for a non-ASCII
686 script, open the file in binary mode and not in text mode with the default
687 (utf8) encoding.
688
Florent Xicluna54467e02010-03-21 12:29:50 +0000689- Issue #8179: Fix macpath.realpath() on a non-existing path.
690
Florent Xiclunafaa663f2010-03-19 13:37:08 +0000691- Issue #8024: Update the Unicode database to 5.2.
692
Benjamin Peterson00888932010-03-18 22:37:38 +0000693- Issue #8168: py_compile now handles files with utf-8 BOMS.
694
Benjamin Peterson689a5582010-03-18 22:29:52 +0000695- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
696 detected.
697
Martin v. Löwis4b003072010-03-16 13:19:21 +0000698- Issue #6716/2: Backslash-replace error output in compilall.
699
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000700- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
701 with Tcl/Tk-8.5.
702
Matthias Klosec33b9022010-03-16 00:36:26 +0000703- Issue #8140: extend compileall to compile single files. Add -i option.

706 the locale.
707
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000708- The internals of the subprocess module on POSIX systems have been replaced
709 by an extension module (_posixsubprocess) so that the fork()+exec() can be
710 done safely without the possibility of deadlock in multithreaded applications.
711
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000712- subprocess.Popen now has restore_signals and start_new_session features.
713 The default of restore_signals=True is a new behavior compared to earlier
714 Python versions. This means that signals such as SIGPIPE are not ignored
715 by default in subprocesses launched by Python (Issue #1652).
716
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000717- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

727 the replacement were all bytes. Patch by Antoine Pitrou.
728
Gerhard Häringf9cee222010-03-05 15:20:03 +0000729- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
730 bugs and allows loading SQLite extensions from shared libraries.
731

Florent Xiclunac279ebf2010-02-27 11:31:21 +0000746- Issue #691291: codecs.open() should not convert end of lines on reading and
747 writing.
748

777 exception of canonical and is_canonical) now accept instances of int
778 and long wherever a Decimal instance is accepted, and implicitly

780 were converted.
781
R. David Murray1f449142010-02-11 00:15:05 +0000782- Issue #7835: shelve should no longer produce mysterious warnings during
783 interpreter shutdown.
784
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000785- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
786 in XML processing instructions and comments. These raw characters are
787 allowed by the XML specification, and are necessary when outputting e.g.
788 PHP code in a processing instruction. Patch by Neil Muller.

801
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000802- Issue #6939: Fix file I/O objects in the `io` module to keep the original
803 file position when calling `truncate()`. It would previously change the
804 file position to the given argument, which goes against the tradition of
805 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
806
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000807- Issue #7610: Reworked implementation of the internal
808 :class:`zipfile.ZipExtFile` class used to represent files stored inside
809 an archive. The new implementation is significantly faster and can
810 be wrapped in a :class:`io.BufferedReader` object for more speedups.
811 It also solves an issue where interleaved calls to `read()` and
812 `readline()` give wrong results. Patch by Nir Aides.
813
Jesse Noller1f0b6582010-01-27 03:36:01 +0000814- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

817 replace it.
818
Benjamin Petersond6326642010-01-27 02:25:58 +0000819- Issue #7792: Registering non-classes to ABCs raised an obscure error.
820
Benjamin Peterson9a11a362010-01-27 01:51:29 +0000821- Issue #7785: Don't accept bytes in FileIO.write().
Benjamin Peterson255058f2010-01-27 01:47:14 +0000822
Ezio Melotti38f00332010-01-25 12:39:47 +0000823- Removed the functions 'verify' and 'vereq' from Lib/test/support.py.
824

Nick Coghlan260bd3e2009-11-16 06:49:25 +0000975- Issue #6816: runpy now provides a run_path function that allows Python code
976 to execute file paths that refer to source or compiled Python files as well
977 as zipfiles, directories and other valid sys.path entries that contain a

Victor Stinnere125f132010-05-15 21:04:43 +0000998 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +0000999 recursive locks as fast as regular non-recursive locks (previously,
1000 they were slower by 10x to 15x).

1020 reading from stdin so that existing input does not confuse it and

1210 algorithm with an improved 'binary-split' algorithm that uses fewer
1211 multiplications and allows many of the multiplications to be
1212 performed using plain C integer arithmetic instead of PyLong
1213 arithmetic. Also uses a lookup table for small arguments.
1214
Mark Dickinson85eacea2010-05-10 16:27:45 +00001215- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing

1286 gcc. (Optimization was unintentionally turned on in gcc
1287 --with-pydebug builds as a result of the issue #1628484 fix,
1288 combined with autoconf's strange choice of default CFLAGS produced

Mark Hammond5a607a32009-05-06 08:04:54 +00001772- Issue #5799: ntpath (ie, os.path on Windows) fully supports UNC pathnames
1773 in all operations, including splitdrive, split, etc. splitunc() now issues
1774 a PendingDeprecation warning.
1775
Eric Smith63376222009-05-05 14:04:18 +00001776- Issue #5920: For float.__format__, change the behavior with the
1777 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1778 to be like 'g' but with at least one decimal point and with a
1779 default precision of 12. Previously, the behavior the same but with
1780 a default precision of 6. This more closely matches str(), and
1781 reduces surprises when adding alignment flags to the empty
1782 presentation type. This also affects the new complex.__format__ in
1783 the same way.
1784
Martin v. Löwis011e8422009-05-05 04:43:17 +00001785- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.
1786
R. David Murrayb18500d2009-05-04 22:59:07 +00001787- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1788 shadowed by classtype's, even if it was None. property now
1789 inserts the __doc__ into the subclass instance __dict__.
1790
Antoine Pitrou244651a2009-05-04 18:56:13 +00001791- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal
1792 sequences. Patch by Nick Barnes and Victor Stinner.

Martin v. Löwisdb12d452009-05-02 18:52:14 +00001795
Benjamin Petersond2e0c792009-05-01 20:40:59 +00001796- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1797 received a new method, detach(). detach() disconnects the underlying stream
1798 from the buffer or text IO and returns it.
1799
Mark Dickinson33841c32009-05-01 15:37:04 +00001800- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1801 floats with absolute value over 1e50. Also remove length
1802 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1803 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001804
Eric Smith741191f2009-05-06 13:08:15 +00001805- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001806 format(complex(1, 2./3), '.5') now produces a sensible result.
1807
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001808- Issue #5864: Fix empty format code formatting for floats so that it
1809 never gives more than the requested number of significant digits.
1810
Eric Smith6dc46f52009-04-27 20:39:49 +00001811- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1817 titlecase, but not their own uppercase.
1818
Benjamin Peterson193152c2009-04-25 01:08:45 +00001819- Issue #5283: Setting __class__ in __del__ caused a segfault.
1820
Mark Dickinsonad476da2009-04-23 19:14:16 +00001821- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1822 z involves nans, infs or negative zeros.
1823
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001824- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001825
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001826- Issue #1869 (and many duplicates): make round(x, n) correctly
1827 rounded for a float x, by using the decimal <-> binary conversions
1828 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1829 consistently agrees with format(x, '.2f').
1830
Benjamin Petersonae937c02009-04-18 20:54:08 +00001831- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1832 some builtin types.
1833
Eric Smith0923d1d2009-04-16 20:16:10 +00001834- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1835
Eric Smith35e84722009-04-16 20:21:28 +00001836- Issue #5515: str.format() type 'n' combined with commas and leading
1837 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001838
1839- Implement PEP 378, Format Specifier for Thousands Separator, for
1840 floats.
1841
Mark Dickinson3370cce2009-04-17 22:40:53 +00001842- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001843 1e11, not 1e12. This avoids printing 13 significant digits in
1844 situations where only 12 of them are correct. Example problem
1845 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1846 long time.)
1847
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001848- Issue #1580: On most platforms, use a 'short' float repr: for a
1849 finite float x, repr(x) now outputs a string based on the shortest
1850 sequence of decimal digits that rounds to x. Previous behaviour was
1851 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001852 Another minor difference is that the new repr switches to
1853 exponential notation at 1e16 instead of the previous 1e17; this
1854 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001855
1856 There's a new sys attribute sys.float_repr_style, which takes
1857 the value 'short' to indicate that we're using short float repr,
1858 and 'legacy' if the short float repr isn't available for one
1859 reason or another.
1860
1861 The float repr change involves incorporating David Gay's 'perfect
1862 rounding' code into the Python core (it's in Python/dtoa.c). As a
1863 secondary consequence, all string-to-float and float-to-string
1864 conversions (including all float formatting operations) will be
1865 correctly rounded on these platforms.
1866
1867 See issue 1580 discussions for details of platforms for which
1868 this change does not apply.
1869
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001870- Issue #5759: float() didn't call __float__ on str subclasses.
1871
Georg Brandlabc38772009-04-12 15:51:51 +00001872- The string.maketrans() function is deprecated; there is a new static method
1873 maketrans() on the bytes and bytearray classes. This removes confusion about
1874 the types string.maketrans() is supposed to work with, and mirrors the
1875 methods available on the str class.
1876
R. David Murraydc6da8a2009-04-09 22:16:43 +00001877- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1881 to avoid compiler warnings.
1882
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001883- Issue #3739: The unicode-internal encoder now reports the number of characters

Benjamin Peterson8f76b492009-04-03 22:22:42 +00002019- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
2020
Benjamin Peterson7fe98532009-04-02 00:33:55 +00002021- Issue #5499: The 'c' code for argument parsing functions now only accepts a

2040
Antoine Pitrou3a652b12009-03-23 18:52:06 +00002041- Issue #4688: Add a heuristic so that tuples and dicts containing only
2042 untrackable objects are not tracked by the garbage collector. This can
2043 reduce the size of collections and therefore the garbage collection overhead
2044 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002167- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2168 it now forces its argument to double before testing for infinity.
2169
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002170- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002179
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002180- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002181 were suppressing all exceptions. These include list() and bytearray().
2182
Mark Dickinson1124e712009-01-28 21:25:58 +00002183- Issue #4707: round(x, n) now returns an integer if x is an integer.
2184 Previously it returned a float.
2185
Antoine Pitroub52ec782009-01-25 16:34:23 +00002186- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2187 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2188 evaluation loop is compiled with a new dispatch mechanism which gives
2189 speedups of up to 20%, depending on the system, on various benchmarks.
2190
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002191- Issue #4874: Most builtin decoders now reject unicode input.

2199 optional module state data.
2200
Mark Dickinson8055afd2009-01-17 10:04:45 +00002201- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2202 type to (void *).
2203
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002204- Issue #4935: The overflow checking code in the expandtabs() method common
2205 to str, bytes and bytearray could be optimized away by the compiler, letting
2206 the interpreter segfault instead of raising an error.
2207
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002208- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2209 __next__ method.
2210
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002211- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2212 function no longer attempt to call the __long__ slot to convert an object
2213 to an integer. Only the __int__ and __trunc__ slots are examined.
2214
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002215- Issue #4893: Use NT threading on CE.
2216
Martin v. Löwisec59d042009-01-12 07:59:10 +00002217- Issue #4915: Port sysmodule to Windows CE.
2218
Antoine Pitrouab868312009-01-10 15:40:25 +00002219- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2220 common cases are optimized thanks to a dedicated fast path and a moderate
2221 amount of loop unrolling.
2222
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002223- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2224 collecting the oldest generation) so that allocating lots of objects without
2225 destroying them does not show quadratic performance. Based on a proposal by
2226 Martin von Löwis at
2227 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2228
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002229- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002230 having been closed (for instance, a read() call could return some
2231 previously buffered data). Patch by Dmitry Vasiliev.
2232
Antoine Pitrou05608432009-01-09 18:53:14 +00002233- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2234 flag to work properly. Furthermore, when specifying -u, the text stdout
2235 and stderr streams have line-by-line buffering enabled (the default being
2236 to buffer arbitrary chunks of data).
2237
Raymond Hettinger35631532009-01-09 03:58:09 +00002238- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2239 instead of ints (reducing its size from 4 to 8 times thereby reducing
2240 Python's overall memory).
2241
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002242- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2243 an existing .py counterpart, override the co_filename attributes of all
2244 code objects if the original filename is obsolete (which can happen if the
2245 file has been renamed, moved, or if it is accessed through different paths).
2246 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2247
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002248- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2249 one byte. Also fixes the meaning of len() so that it returns the number of
2250 items, rather than the size in bytes.
2251
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002252- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2253
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002254- Issue #4747: When the terminal does not use utf-8, executing a script with
2255 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2256
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002257- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002258 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002259
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002260- Issue #3680: Reference cycles created through a dict, set or deque iterator
2261 did not get collected.
2262
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002263- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2264 where the tp_hash and tp_dict slots are both NULL.
2265
Georg Brandlccc47b62008-12-28 11:44:14 +00002266- Issue #4759: None is now allowed as the first argument of
2267 bytearray.translate(). It was always allowed for bytes.translate().
2268
Skip Montanaro80072cb2008-12-23 03:51:14 +00002269- Added test case to ensure attempts to read from a file opened for writing
2270 fail.
2271
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002272- Issue #3106: Speedup some comparisons (str/str and int/int).

2275 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2276
Antoine Pitrou621601a2008-12-17 23:18:19 +00002277- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2278 print elapsed times, not only when some objects are uncollectable /
2279 unreachable. Original patch by Neil Schemenauer.
2280
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002281- Issue #3439: Add a bit_length method to int.
2282
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002283- Issue #2173: When getting device encoding, check that return value of
2284 nl_langinfo is not the empty string. This was causing silent build
2285 failures on OS X.
2286
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002287- Issue #4597: Fixed several opcodes that weren't always propagating
2288 exceptions.
2289
2290- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002291 context manager returns a value that cannot be converted to a bool.
2292
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002293- Issue #4445: Replace "sizeof(PyBytesObject)" with
2294 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2295 bytes instances. On a typical machine this saves 3 bytes of memory
2296 (on average) per allocation of a bytes instance.
2297
Christian Heimesa872de52008-12-05 08:26:55 +00002298- Issue #4533: File read operation was dreadfully slow due to a slowly
2299 growing read buffer. Fixed by using the same growth rate algorithm as
2300 Python 2.x.
2301
Antoine Pitrou5504e892008-12-06 21:27:53 +00002302- Issue #4509: Various issues surrounding resize of bytearray objects to
2303 which there are buffer exports (e.g. memoryview instances).
2304
Georg Brandlf9734072008-12-07 15:30:06 +00002305- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2306 method on file objects with closefd=False. The file descriptor is still
2307 kept open but the file object behaves like a closed file. The ``FileIO``
2308 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002309
Antoine Pitroubc420402008-12-07 20:14:49 +00002310- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2318 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2319 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2320 of using the replace error handler in PyUnicode_DecodeUTF8().

2926 Lib/tkinter/test/test_tkinter/test_loadtk. With this, these tests demonstrate
2927 the same behaviour as test_ttkguionly (and now also test_tk) which is to

Vinay Sajipad5fa2f2009-04-27 13:55:05 +00002931 that should cause a test to be skipped are now done using import_module
R. David Murraya21e4ca2009-03-31 23:16:50 +00002932 from test support, which does the conversion.
