Ezio Melotti25bc0192010-07-03 05:18:50 +0000609- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the

611 of the number of bytes specified by the start byte.
612 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
613 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
614 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
615 Previous versions returned a single u'\ufffd'.

2236 deprecate PyOS_ascii_strtod and PyOS_ascii_atof.
2237
Eric Smith741191f2009-05-06 13:08:15 +00002238- Issue #3382: float.__format__, complex.__format__, and %-formatting

2244 a PendingDeprecation warning.
2245
Eric Smith63376222009-05-05 14:04:18 +00002246- Issue #5920: For float.__format__, change the behavior with the
2247 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
2248 to be like 'g' but with at least one decimal point and with a
2249 default precision of 12. Previously, the behavior the same but with
2250 a default precision of 6. This more closely matches str(), and
2251 reduces surprises when adding alignment flags to the empty
2252 presentation type. This also affects the new complex.__format__ in
2253 the same way.
2254
Martin v. Löwis011e8422009-05-05 04:43:17 +00002255- Implement PEP 383, Non-decodable Bytes in System Character Interfaces.

Benjamin Petersond2e0c792009-05-01 20:40:59 +00002266- Issue #5883: In the io module, the BufferedIOBase and TextIOBase ABCs have
2267 received a new method, detach(). detach() disconnects the underlying stream
2268 from the buffer or text IO and returns it.
2269
Mark Dickinson33841c32009-05-01 15:37:04 +00002270- Issue #5859: Remove switch from '%f' to '%g'-style formatting for
2271 floats with absolute value over 1e50. Also remove length
2272 restrictions for float formatting: '%.67f' % 12.34 and '%.120e' %
2273 12.34 no longer raise an exception.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00002296- Issue #1869 (and many duplicates): make round(x, n) correctly
2297 rounded for a float x, by using the decimal <-> binary conversions
2298 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2299 consistently agrees with format(x, '.2f').
2300
Benjamin Petersonae937c02009-04-18 20:54:08 +00002301- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
2302 some builtin types.
2303
Eric Smith0923d1d2009-04-16 20:16:10 +00002304- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
2305
Eric Smith35e84722009-04-16 20:21:28 +00002306- Issue #5515: str.format() type 'n' combined with commas and leading
2307 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002308
2309- Implement PEP 378, Format Specifier for Thousands Separator, for
2310 floats.
2311
Mark Dickinson3370cce2009-04-17 22:40:53 +00002312- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002313 1e11, not 1e12. This avoids printing 13 significant digits in
2314 situations where only 12 of them are correct. Example problem
2315 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2316 long time.)
2317
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002318- Issue #1580: On most platforms, use a 'short' float repr: for a
2319 finite float x, repr(x) now outputs a string based on the shortest
2320 sequence of decimal digits that rounds to x. Previous behaviour was
2321 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002322 Another minor difference is that the new repr switches to
2323 exponential notation at 1e16 instead of the previous 1e17; this
2324 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002325
2326 There's a new sys attribute sys.float_repr_style, which takes
2327 the value 'short' to indicate that we're using short float repr,
2328 and 'legacy' if the short float repr isn't available for one
2329 reason or another.
2330
2331 The float repr change involves incorporating David Gay's 'perfect
2332 rounding' code into the Python core (it's in Python/dtoa.c). As a
2333 secondary consequence, all string-to-float and float-to-string
2334 conversions (including all float formatting operations) will be
2335 correctly rounded on these platforms.
2336
Georg Brandl442d3b32010-08-01 22:33:12 +00002337 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002338 this change does not apply.
2339
Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002340- Issue #5759: float() didn't call __float__ on str subclasses.
2341
Georg Brandlabc38772009-04-12 15:51:51 +00002342- The string.maketrans() function is deprecated; there is a new static method
2343 maketrans() on the bytes and bytearray classes. This removes confusion about
2344 the types string.maketrans() is supposed to work with, and mirrors the
2345 methods available on the str class.
2346
R. David Murraydc6da8a2009-04-09 22:16:43 +00002347- Issue #2170: refactored xml.dom.minidom.normalize, increasing both

2512 untrackable objects are not tracked by the garbage collector. This can
2513 reduce the size of collections and therefore the garbage collection overhead
2514 on long-running programs, depending on their particular use of datatypes.

2583
Lars Gustäbel42e00912009-03-22 20:34:29 +00002584- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2585 forever on incomplete input. That caused tarfile.open() to hang when used
2586 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or

Antoine Pitrou0ae29cf2009-03-13 22:33:17 +00002595- The error detection code in FileIO.close() could fail to reflect the `errno`
2596 value, and report it as -1 instead.
2597
Antoine Pitroua28fcfd2009-03-13 23:42:55 +00002598- Issue #5016: FileIO.seekable() could return False if the file position

2607 when packing an integer: struct.pack('=L', -1) now raises
Mark Dickinsonb40b9472009-03-29 16:58:21 +00002608 struct.error instead of returning b'\xff\xff\xff\xff'. The
2609 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants
2610 have been removed from the struct module.

2629 contained non ascii character on windows.
2630
Benjamin Petersonf5b52242009-03-02 23:31:26 +00002631- Issue #4626: compile(), exec(), and eval() ignore the coding cookie if the
2632 source has already been decoded into str.
2633
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002634- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2635 rotating the object pointer by 4 bits to the right.
2636
Mark Dickinson87ec0852009-02-09 17:15:59 +00002637- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2638 it now forces its argument to double before testing for infinity.
2639
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002640- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2641 returns a non-number type.
2642
Benjamin Peterson87618552009-02-08 15:00:52 +00002643- Issue #5182: Removed memoryview.__str__.

2648 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002649
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002650- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002651 were suppressing all exceptions. These include list() and bytearray().
2652
Mark Dickinson1124e712009-01-28 21:25:58 +00002653- Issue #4707: round(x, n) now returns an integer if x is an integer.
2654 Previously it returned a float.
2655
Antoine Pitroub52ec782009-01-25 16:34:23 +00002656- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2657 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2658 evaluation loop is compiled with a new dispatch mechanism which gives
2659 speedups of up to 20%, depending on the system, on various benchmarks.
2660
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002661- Issue #4874: Most builtin decoders now reject unicode input.

2667
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002668- Issue #4838: When a module is deallocated, free the memory backing the
2669 optional module state data.
2670
Mark Dickinson8055afd2009-01-17 10:04:45 +00002671- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2672 type to (void *).
2673
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002674- Issue #4935: The overflow checking code in the expandtabs() method common
2675 to str, bytes and bytearray could be optimized away by the compiler, letting
2676 the interpreter segfault instead of raising an error.
2677
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002678- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2679 __next__ method.
2680
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002681- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2682 function no longer attempt to call the __long__ slot to convert an object
2683 to an integer. Only the __int__ and __trunc__ slots are examined.
2684
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002685- Issue #4893: Use NT threading on CE.
2686
Martin v. Löwisec59d042009-01-12 07:59:10 +00002687- Issue #4915: Port sysmodule to Windows CE.
2688
Antoine Pitrouab868312009-01-10 15:40:25 +00002689- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2690 common cases are optimized thanks to a dedicated fast path and a moderate
2691 amount of loop unrolling.
2692
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002693- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2694 collecting the oldest generation) so that allocating lots of objects without
2695 destroying them does not show quadratic performance. Based on a proposal by
2696 Martin von Löwis at
2697 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2698
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002699- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002700 having been closed (for instance, a read() call could return some
2701 previously buffered data). Patch by Dmitry Vasiliev.
2702
Antoine Pitrou05608432009-01-09 18:53:14 +00002703- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2704 flag to work properly. Furthermore, when specifying -u, the text stdout
2705 and stderr streams have line-by-line buffering enabled (the default being
2706 to buffer arbitrary chunks of data).
2707
Raymond Hettinger35631532009-01-09 03:58:09 +00002708- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2709 instead of ints (reducing its size from 4 to 8 times thereby reducing
2710 Python's overall memory).
2711
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002712- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2713 an existing .py counterpart, override the co_filename attributes of all
2714 code objects if the original filename is obsolete (which can happen if the
2715 file has been renamed, moved, or if it is accessed through different paths).
2716 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2717
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002718- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2719 one byte. Also fixes the meaning of len() so that it returns the number of
2720 items, rather than the size in bytes.
2721
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002722- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2723
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002724- Issue #4747: When the terminal does not use utf-8, executing a script with
2725 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2726
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002727- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002728 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002729
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002730- Issue #3680: Reference cycles created through a dict, set or deque iterator
2731 did not get collected.
2732
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002733- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2734 where the tp_hash and tp_dict slots are both NULL.
2735
Georg Brandlccc47b62008-12-28 11:44:14 +00002736- Issue #4759: None is now allowed as the first argument of
2737 bytearray.translate(). It was always allowed for bytes.translate().
2738
Skip Montanaro80072cb2008-12-23 03:51:14 +00002739- Added test case to ensure attempts to read from a file opened for writing
2740 fail.
2741
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002742- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002744- Issue #2183: Simplify and optimize bytecode for list, dict and set
2745 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2746
Antoine Pitrou621601a2008-12-17 23:18:19 +00002747- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2748 print elapsed times, not only when some objects are uncollectable /
2749 unreachable. Original patch by Neil Schemenauer.
2750
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002751- Issue #3439: Add a bit_length method to int.
2752
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002753- Issue #2173: When getting device encoding, check that return value of
2754 nl_langinfo is not the empty string. This was causing silent build
2755 failures on OS X.
2756
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002757- Issue #4597: Fixed several opcodes that weren't always propagating
2758 exceptions.
2759
2760- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002761 context manager returns a value that cannot be converted to a bool.
2762
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002763- Issue #4445: Replace "sizeof(PyBytesObject)" with
2764 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2765 bytes instances. On a typical machine this saves 3 bytes of memory
2766 (on average) per allocation of a bytes instance.
2767
Christian Heimesa872de52008-12-05 08:26:55 +00002768- Issue #4533: File read operation was dreadfully slow due to a slowly
2769 growing read buffer. Fixed by using the same growth rate algorithm as
2770 Python 2.x.
2771
Antoine Pitrou5504e892008-12-06 21:27:53 +00002772- Issue #4509: Various issues surrounding resize of bytearray objects to
2773 which there are buffer exports (e.g. memoryview instances).
2774
Georg Brandlf9734072008-12-07 15:30:06 +00002775- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2776 method on file objects with closefd=False. The file descriptor is still
2777 kept open but the file object behaves like a closed file. The ``FileIO``
2778 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002779
Antoine Pitroubc420402008-12-07 20:14:49 +00002780- Issue #4569: Interpreter crash when mutating a memoryview with an item size
2781 larger than 1.

2786
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002787- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2788 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2789 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2790 of using the replace error handler in PyUnicode_DecodeUTF8().
