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.

219 implement the relevant rich comparison methods.
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

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

369
Alexandre Vassalotti2db046d2009-07-22 03:56:36 +0000370- Issue #6151: Made PyDescr_COMMON conform to standard C (like PyObject_HEAD
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.

385- Issue #1419652: Change the first argument to PyImport_AppendInittab() to
386 ``const char *`` as the string is stored beyond the call.
387
Benjamin Peterson05159c42009-12-03 03:01:27 +0000388- Issue #2422: When compiled with the ``--with-valgrind`` option, the
389 pymalloc allocator will be automatically disabled when running under
390 Valgrind. This gives improved memory leak detection when running
391 under Valgrind, while taking advantage of pymalloc at other times.

477
Mark Dickinsonc69160e2010-05-04 14:35:33 +0000478- Issue #8567: Fix precedence of signals in Decimal module: when a
479 Decimal operation raises multiple signals and more than one of those
480 signals is trapped, the specification determines the order in which
481 the signals should be handled. In many cases this order wasn't
482 being followed, leading to the wrong Python exception being raised.
483
Antoine Pitrou6be88762010-05-03 16:48:20 +0000484- Issue #7865: The close() method of :mod:`io` objects should not swallow

514 and mappings.
515
Antoine Pitrou3bcba8e2010-04-25 22:01:43 +0000516- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown,
517 where the method could block indefinitely if called just before the
518 event loop started running. This also fixes the occasional freezes
519 witnessed in test_httpservers.
520
Antoine Pitrou40f08742010-04-24 22:04:40 +0000521- Issue #8524: When creating an SSL socket, the timeout value of the
522 original socket wasn't retained (instead, a socket with a positive timeout
523 would be turned into a non-blocking SSL socket).
524
Antoine Pitroud3f8ab82010-04-24 21:26:44 +0000525- Issue #5103: SSL handshake would ignore the socket timeout and block
526 indefinitely if the other end didn't respond.
527
528- The do_handshake() method of SSL objects now adjusts the blocking mode of
529 the SSL structure if necessary (as other methods already do).
530
Victor Stinner13bb71c2010-04-23 21:41:56 +0000531- Issue #8391: os.execvpe() and os.getenv() supports unicode with surrogates

613 7bit rather than sometimes being marked as 8bit.
614
Tarek Ziadé46cd93a2010-04-12 08:23:49 +0000615- Issue #8375: test_distutils now checks if the temporary directory are still
616 present before it cleans them.
617

619 to cover recent locale changes and additions.
620
Antoine Pitrou04f6a322010-04-05 21:40:07 +0000621- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
622 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`
623 and `ssl.OPENSSL_VERSION_NUMBER`.
624
Raymond Hettingerc50846a2010-04-05 18:56:31 +0000625- Add functools.total_ordering() and functools.cmp_to_key().
626
Mark Dickinson089b00c2010-04-03 15:51:03 +0000627- Issue #8257: The Decimal construct now accepts a float instance
628 directly, converting that float to a Decimal of equal value:
629
630 >>> Decimal(1.1)
631 Decimal('1.100000000000000088817841970012523233890533447265625')
632
Mark Dickinson98127c32010-04-03 11:18:52 +0000633- Issue #8294: The Fraction constructor now accepts Decimal and float
634 instances directly.
635
Mark Dickinsonac256ab2010-04-03 11:08:14 +0000636- Issue #7279: Comparisons involving a Decimal signaling NaN now
637 signal InvalidOperation instead of returning False. (Comparisons
638 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
639 are now hashable; Decimal signaling NaNs remain unhashable.
640
641- Issue #2531: Comparison operations between floats and Decimal
642 instances now return a result based on the numeric values of the
643 operands; previously they returned an arbitrary result based on
644 the relative ordering of id(float) and id(Decimal).
645
Raymond Hettinger9c01e442010-04-03 10:32:58 +0000646- Added a subtract() method to collections.Counter().
647
Barry Warsawd5f9bf52010-03-31 21:36:22 +0000648- Issue #8233: When run as a script, py_compile.py optionally takes a single
649 argument `-` which tells it to read files to compile from stdin. Each line
650 is read on demand and the named file is compiled immediately. (Original
651 patch by Piotr Ożarowski).
652
Florent Xicluna806d8cf2010-03-30 19:34:18 +0000653- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
654 form feed (0x0C) are now considered linebreaks, as specified in Unicode
655 Standard Annex #14. See issue #7643.
656 http://www.unicode.org/reports/tr14/
657
Mark Dickinsonab4d63b2010-03-27 11:16:00 +0000658- Comparisons using one of <, <=, >, >= between a complex instance and
659 a Fractions instance now raise TypeError instead of returning
660 True/False. This makes Fraction <=> complex comparisons consistent with
661 int <=> complex, float <=> complex, and complex <=> complex comparisons.
662
Antoine Pitrou39b35432010-03-23 00:25:54 +0000663- Issue #8139: ossaudiodev didn't initialize its types properly, therefore

665 Initial patch by Bertrand Janin.
666
Florent Xiclunafd1b0932010-03-28 00:25:02 +0000667- Issue #8205: Remove the "Modules" directory from sys.path when Python is
668 running from the build directory (POSIX only).
669
Antoine Pitrou910bd512010-03-22 20:11:09 +0000670- Issue #7512: shutil.copystat() could raise an OSError when the filesystem
671 didn't support chflags() (for example ZFS under FreeBSD). The error is
672 now silenced.
673
R. David Murrayca2edce2010-03-22 17:48:48 +0000674- Issue #7860: platform.uname now reports the correct 'machine' type
675 when Python is running in WOW64 mode on 64 bit Windows.
676
Antoine Pitrou3c0fac22010-03-26 19:36:14 +0000677- Issue #3890, #8222: Fix recv() and recv_into() on non-blocking SSL sockets.
678 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
679 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou5733c082010-03-22 14:49:10 +0000680
Victor Stinnere3a1f6d2010-03-22 01:58:35 +0000681- Issue #4282: Fix the main function of the profile module for a non-ASCII

683 (utf8) encoding.
684
Florent Xicluna54467e02010-03-21 12:29:50 +0000685- Issue #8179: Fix macpath.realpath() on a non-existing path.
686

690
Benjamin Peterson689a5582010-03-18 22:29:52 +0000691- ``tokenize.detect_encoding`` now returns ``'utf-8-sig'`` when a UTF-8 BOM is
692 detected.
693
Martin v. Löwis4b003072010-03-16 13:19:21 +0000694- Issue #6716/2: Backslash-replace error output in compilall.
695
Matthias Klosea6d9abf2010-03-16 10:51:28 +0000696- Issue #4961: Inconsistent/wrong result of askyesno function in tkMessageBox
697 with Tcl/Tk-8.5.
698

702 the locale.
703
Gregory P. Smitha31f57c2010-03-14 06:52:18 +0000704- The internals of the subprocess module on POSIX systems have been replaced
705 by an extension module (_posixsubprocess) so that the fork()+exec() can be
706 done safely without the possibility of deadlock in multithreaded applications.
707
Gregory P. Smith580d60c2010-03-14 07:13:25 +0000708- subprocess.Popen now has restore_signals and start_new_session features.
709 The default of restore_signals=True is a new behavior compared to earlier
710 Python versions. This means that signals such as SIGPIPE are not ignored
711 by default in subprocesses launched by Python (Issue #1652).
712
Florent Xiclunaf15351d2010-03-13 23:24:31 +0000713- Issue #6472: The xml.etree package is updated to ElementTree 1.3. The

723 the replacement were all bytes. Patch by Antoine Pitrou.
724
Gerhard Häringf9cee222010-03-05 15:20:03 +0000725- The sqlite3 module was updated to pysqlite 2.6.0. This fixes several obscure
726 bugs and allows loading SQLite extensions from shared libraries.

773 exception of canonical and is_canonical) now accept instances of int
774 and long wherever a Decimal instance is accepted, and implicitly
775 convert that argument to Decimal. Previously only some arguments
776 were converted.
777
R. David Murray1f449142010-02-11 00:15:05 +0000778- Issue #7835: shelve should no longer produce mysterious warnings during
779 interpreter shutdown.
780
Antoine Pitrou99f69ee2010-02-09 17:25:47 +0000781- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">")
782 in XML processing instructions and comments. These raw characters are
783 allowed by the XML specification, and are necessary when outputting e.g.
784 PHP code in a processing instruction. Patch by Neil Muller.

796 type is specified. Patch by Brian Curtin.
797
Antoine Pitrou905a2ff2010-01-31 22:47:27 +0000798- Issue #6939: Fix file I/O objects in the `io` module to keep the original
799 file position when calling `truncate()`. It would previously change the
800 file position to the given argument, which goes against the tradition of
801 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
802
Antoine Pitroua32f9a22010-01-27 21:18:57 +0000803- Issue #7610: Reworked implementation of the internal
804 :class:`zipfile.ZipExtFile` class used to represent files stored inside
805 an archive. The new implementation is significantly faster and can
806 be wrapped in a :class:`io.BufferedReader` object for more speedups.
807 It also solves an issue where interleaved calls to `read()` and
808 `readline()` give wrong results. Patch by Nir Aides.
809
Jesse Noller1f0b6582010-01-27 03:36:01 +0000810- Issue #6963: Added "maxtasksperchild" argument to multiprocessing.Pool,

813 replace it.
814
Benjamin Petersond6326642010-01-27 02:25:58 +0000815- Issue #7792: Registering non-classes to ABCs raised an obscure error.

924 ownership when the group is not forced, because the group may be different
925 from the user's group and inherit from its container when the test is run.
926
Antoine Pitrou7b0d4a22009-11-28 16:12:28 +0000927- Issue #4486: When an exception has an explicit cause, do not print its

970
Nick Coghlan260bd3e2009-11-16 06:49:25 +0000971- Issue #6816: runpy now provides a run_path function that allows Python code
972 to execute file paths that refer to source or compiled Python files as well
973 as zipfiles, directories and other valid sys.path entries that contain a
974 __main__.py file. This allows applications that run other Python scripts to

Victor Stinnere125f132010-05-15 21:04:43 +0000994 default when instantiating a `threading.RLock` object. This makes
Antoine Pitrou434736a2009-11-10 18:46:01 +0000995 recursive locks as fast as regular non-recursive locks (previously,
996 they were slower by 10x to 15x).

1016 reading from stdin so that existing input does not confuse it and
1017 lead to incorrect entry or an IOError. It also properly flushes it
1018 afterwards to avoid the terminal echoing the input afterwards on
1019 OSes such as Solaris.

1206 algorithm with an improved 'binary-split' algorithm that uses fewer
1207 multiplications and allows many of the multiplications to be
1208 performed using plain C integer arithmetic instead of PyLong
1209 arithmetic. Also uses a lookup table for small arguments.
1210
Mark Dickinson85eacea2010-05-10 16:27:45 +00001211- Issue #8674: Fixed a number of incorrect or undefined-behaviour-inducing

1282 gcc. (Optimization was unintentionally turned on in gcc

1469 leak-chasing test runs give sensible results. The previous method of

Eric Smith63376222009-05-05 14:04:18 +00001772- Issue #5920: For float.__format__, change the behavior with the
1773 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
1774 to be like 'g' but with at least one decimal point and with a
1775 default precision of 12. Previously, the behavior the same but with
1776 a default precision of 6. This more closely matches str(), and
1777 reduces surprises when adding alignment flags to the empty
1778 presentation type. This also affects the new complex.__format__ in
1779 the same way.

Martin v. Löwis011e8422009-05-05 04:43:17 +00001781- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

R. David Murrayb18500d2009-05-04 22:59:07 +00001783- Issue #5890: in subclasses of 'property' the __doc__ attribute was
1784 shadowed by classtype's, even if it was None. property now
1785 inserts the __doc__ into the subclass instance __dict__.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00001792- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
1793 received a new method, detach(). detach() disconnects the underlying stream
1794 from the buffer or text IO and returns it.
1795
Mark Dickinson33841c32009-05-01 15:37:04 +00001796- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
1797 floats with absolute value over 1e50. Also remove length
1798 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
1799 12.34 no longer raise an exception.
Mark Dickinsonf489caf2009-05-01 11:42:00 +00001800
Eric Smith741191f2009-05-06 13:08:15 +00001801- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00001802 format(complex(1, 2./3), '.5') now produces a sensible result.
1803
Mark Dickinsond3ca5572009-04-29 18:47:07 +00001804- Issue #5864: Fix empty format code formatting for floats so that it
1805 never gives more than the requested number of significant digits.
1806
Eric Smith6dc46f52009-04-27 20:39:49 +00001807- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes

1814
Benjamin Peterson193152c2009-04-25 01:08:45 +00001815- Issue #5283: Setting __class__ in __del__ caused a segfault.
1816
Mark Dickinsonad476da2009-04-23 19:14:16 +00001817- Issue #5816: complex(repr(z)) now recovers z exactly, even when
1818 z involves nans, infs or negative zeros.
1819
Mark Dickinson4a16e3a2009-04-23 19:15:48 +00001820- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +00001821
Mark Dickinsone6a076d2009-04-18 11:48:33 +00001822- Issue #1869 (and many duplicates): make round(x, n) correctly
1823 rounded for a float x, by using the decimal <-> binary conversions
1824 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
1825 consistently agrees with format(x, '.2f').
1826
Benjamin Petersonae937c02009-04-18 20:54:08 +00001827- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
1828 some builtin types.
1829
Eric Smith0923d1d2009-04-16 20:16:10 +00001830- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
1831
Eric Smith35e84722009-04-16 20:21:28 +00001832- Issue #5515: str.format() type 'n' combined with commas and leading
1833 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00001834
1835- Implement PEP 378, Format Specifier for Thousands Separator, for
1836 floats.
1837
Mark Dickinson3370cce2009-04-17 22:40:53 +00001838- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001839 1e11, not 1e12. This avoids printing 13 significant digits in
1840 situations where only 12 of them are correct. Example problem
1841 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
1842 long time.)
1843
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001844- Issue #1580: On most platforms, use a 'short' float repr: for a
1845 finite float x, repr(x) now outputs a string based on the shortest
1846 sequence of decimal digits that rounds to x. Previous behaviour was
1847 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00001848 Another minor difference is that the new repr switches to
1849 exponential notation at 1e16 instead of the previous 1e17; this
1850 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00001851
1852 There's a new sys attribute sys.float_repr_style, which takes
1853 the value 'short' to indicate that we're using short float repr,
1854 and 'legacy' if the short float repr isn't available for one
1855 reason or another.
1856
1857 The float repr change involves incorporating David Gay's 'perfect
1858 rounding' code into the Python core (it's in Python/dtoa.c). As a
1859 secondary consequence, all string-to-float and float-to-string
1860 conversions (including all float formatting operations) will be
1861 correctly rounded on these platforms.
1862
1863 See issue 1580 discussions for details of platforms for which
1864 this change does not apply.
1865
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00001866- Issue #5759: float() didn't call __float__ on str subclasses.
1867
Georg Brandlabc38772009-04-12 15:51:51 +00001868- The string.maketrans() function is deprecated; there is a new static method
1869 maketrans() on the bytes and bytearray classes. This removes confusion about
1870 the types string.maketrans() is supposed to work with, and mirrors the
1871 methods available on the str class.
1872
R. David Murraydc6da8a2009-04-09 22:16:43 +00001873- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

1875
Matthias Klose091c7b12009-04-07 13:24:27 +00001876- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
1877 to avoid compiler warnings.
1878
Walter Dörwald8dc33d52009-05-06 14:41:26 +00001879- Issue #3739: The unicode-internal encoder now reports the number of characters

2038 untrackable objects are not tracked by the garbage collector. This can
2039 reduce the size of collections and therefore the garbage collection overhead
2040 on long-running programs, depending on their particular use of datatypes.

Mark Dickinson87ec0852009-02-09 17:15:59 +00002163- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2164 it now forces its argument to double before testing for infinity.
2165
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002166- Issue #5137: Make len() correctly raise a TypeError when a __len__ method

2174 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002175
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002176- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002177 were suppressing all exceptions. These include list() and bytearray().
2178
Mark Dickinson1124e712009-01-28 21:25:58 +00002179- Issue #4707: round(x, n) now returns an integer if x is an integer.
2180 Previously it returned a float.
2181
Antoine Pitroub52ec782009-01-25 16:34:23 +00002182- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2183 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2184 evaluation loop is compiled with a new dispatch mechanism which gives
2185 speedups of up to 20%, depending on the system, on various benchmarks.
2186
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002187- Issue #4874: Most builtin decoders now reject unicode input.

2195 optional module state data.
2196
Mark Dickinson8055afd2009-01-17 10:04:45 +00002197- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2198 type to (void *).
2199
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002200- Issue #4935: The overflow checking code in the expandtabs() method common
2201 to str, bytes and bytearray could be optimized away by the compiler, letting
2202 the interpreter segfault instead of raising an error.
2203
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002204- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2205 __next__ method.
2206
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002207- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2208 function no longer attempt to call the __long__ slot to convert an object
2209 to an integer. Only the __int__ and __trunc__ slots are examined.
2210
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002211- Issue #4893: Use NT threading on CE.
2212

2214
Antoine Pitrouab868312009-01-10 15:40:25 +00002215- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2216 common cases are optimized thanks to a dedicated fast path and a moderate
2217 amount of loop unrolling.
2218
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002219- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2220 collecting the oldest generation) so that allocating lots of objects without
2221 destroying them does not show quadratic performance. Based on a proposal by
2222 Martin von Löwis at
2223 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2224
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002225- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002226 having been closed (for instance, a read() call could return some
2227 previously buffered data). Patch by Dmitry Vasiliev.
2228
Antoine Pitrou05608432009-01-09 18:53:14 +00002229- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2230 flag to work properly. Furthermore, when specifying -u, the text stdout
2231 and stderr streams have line-by-line buffering enabled (the default being
2232 to buffer arbitrary chunks of data).
2233
Raymond Hettinger35631532009-01-09 03:58:09 +00002234- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2235 instead of ints (reducing its size from 4 to 8 times thereby reducing
2236 Python's overall memory).
2237
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002238- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2239 an existing .py counterpart, override the co_filename attributes of all
2240 code objects if the original filename is obsolete (which can happen if the
2241 file has been renamed, moved, or if it is accessed through different paths).
2242 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2243
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002244- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2245 one byte. Also fixes the meaning of len() so that it returns the number of
2246 items, rather than the size in bytes.
2247
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002248- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2249
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002250- Issue #4747: When the terminal does not use utf-8, executing a script with
2251 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2252
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002253- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002254 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002255
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002256- Issue #3680: Reference cycles created through a dict, set or deque iterator
2257 did not get collected.
2258
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002259- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2260 where the tp_hash and tp_dict slots are both NULL.
2261
Georg Brandlccc47b62008-12-28 11:44:14 +00002262- Issue #4759: None is now allowed as the first argument of
2263 bytearray.translate(). It was always allowed for bytes.translate().
2264
Skip Montanaro80072cb2008-12-23 03:51:14 +00002265- Added test case to ensure attempts to read from a file opened for writing
2266 fail.
2267
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002268- Issue #3106: Speedup some comparisons (str/str and int/int).

2271 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2272
Antoine Pitrou621601a2008-12-17 23:18:19 +00002273- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2274 print elapsed times, not only when some objects are uncollectable /
2275 unreachable. Original patch by Neil Schemenauer.
2276
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002277- Issue #3439: Add a bit_length method to int.
2278
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002279- Issue #2173: When getting device encoding, check that return value of
2280 nl_langinfo is not the empty string. This was causing silent build
2281 failures on OS X.
2282
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002283- Issue #4597: Fixed several opcodes that weren't always propagating
2284 exceptions.
2285
2286- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002287 context manager returns a value that cannot be converted to a bool.
2288
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002289- Issue #4445: Replace "sizeof(PyBytesObject)" with
2290 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2291 bytes instances. On a typical machine this saves 3 bytes of memory
2292 (on average) per allocation of a bytes instance.
2293
Christian Heimesa872de52008-12-05 08:26:55 +00002294- Issue #4533: File read operation was dreadfully slow due to a slowly
2295 growing read buffer. Fixed by using the same growth rate algorithm as
2296 Python 2.x.
2297
Antoine Pitrou5504e892008-12-06 21:27:53 +00002298- Issue #4509: Various issues surrounding resize of bytearray objects to
2299 which there are buffer exports (e.g. memoryview instances).
2300
Georg Brandlf9734072008-12-07 15:30:06 +00002301- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2302 method on file objects with closefd=False. The file descriptor is still
2303 kept open but the file object behaves like a closed file. The ``FileIO``
2304 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002305
Antoine Pitroubc420402008-12-07 20:14:49 +00002306- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2307 larger than 1.

2312
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002313- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2314 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2315 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2316 of using the replace error handler in PyUnicode_DecodeUTF8().
