Ezio Melotti25bc0192010-07-03 05:18:50 +0000641- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
642 start byte and the continuation byte(s) are now considered invalid, instead
643 of the number of bytes specified by the start byte.
644 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
645 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
646 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
647 Previous versions returned a single u'\ufffd'.

Eric Smith63376222009-05-05 14:04:18 +00002278- Issue #5920: For float.__format__, change the behavior with the

2280 to be like 'g' but with at least one decimal point and with a
2281 default precision of 12. Previously, the behavior the same but with
2282 a default precision of 6. This more closely matches str(), and
2283 reduces surprises when adding alignment flags to the empty
2284 presentation type. This also affects the new complex.__format__ in
2285 the same way.

Eric Smith741191f2009-05-06 13:08:15 +00002307- Issue #1588: Add complex.__format__. For example,
Eric Smith58a42242009-04-30 01:00:33 +00002308 format(complex(1, 2./3), '.5') now produces a sensible result.

Mark Dickinsone6a076d2009-04-18 11:48:33 +00002328- Issue #1869 (and many duplicates): make round(x, n) correctly
2329 rounded for a float x, by using the decimal <-> binary conversions
2330 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
2331 consistently agrees with format(x, '.2f').
2332
Benjamin Petersonae937c02009-04-18 20:54:08 +00002333- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on

2337
Eric Smith35e84722009-04-16 20:21:28 +00002338- Issue #5515: str.format() type 'n' combined with commas and leading
2339 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +00002340
2341- Implement PEP 378, Format Specifier for Thousands Separator, for
2342 floats.
2343
Mark Dickinson3370cce2009-04-17 22:40:53 +00002344- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002345 1e11, not 1e12. This avoids printing 13 significant digits in
2346 situations where only 12 of them are correct. Example problem
2347 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
2348 long time.)
2349
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002350- Issue #1580: On most platforms, use a 'short' float repr: for a
2351 finite float x, repr(x) now outputs a string based on the shortest
2352 sequence of decimal digits that rounds to x. Previous behaviour was
2353 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +00002354 Another minor difference is that the new repr switches to
2355 exponential notation at 1e16 instead of the previous 1e17; this
2356 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002357
2358 There's a new sys attribute sys.float_repr_style, which takes
2359 the value 'short' to indicate that we're using short float repr,
2360 and 'legacy' if the short float repr isn't available for one
2361 reason or another.
2362
2363 The float repr change involves incorporating David Gay's 'perfect
2364 rounding' code into the Python core (it's in Python/dtoa.c). As a
2365 secondary consequence, all string-to-float and float-to-string
2366 conversions (including all float formatting operations) will be
2367 correctly rounded on these platforms.
2368
Georg Brandl442d3b32010-08-01 22:33:12 +00002369 See issue #1580 discussions for details of platforms for which
Mark Dickinsonb08a53a2009-04-16 19:52:09 +00002370 this change does not apply.

Benjamin Peterson2808d3c2009-04-15 21:34:27 +00002372- Issue #5759: float() didn't call __float__ on str subclasses.
2373
Georg Brandlabc38772009-04-12 15:51:51 +00002374- The string.maketrans() function is deprecated; there is a new static method
2375 maketrans() on the bytes and bytearray classes. This removes confusion about
2376 the types string.maketrans() is supposed to work with, and mirrors the
2377 methods available on the str class.

2602 bytes already but the failure was non-obvious.
2603
Jesse Noller7af4ef82009-03-30 16:47:15 +00002604- Issue #5177: Multiprocessing's SocketListener class now uses

2611 (typically /dev/zero under Unix) could crash the interpreter.
2612
Benjamin Peterson59406a92009-03-26 17:10:29 +00002613- The max_buffer_size arguments of io.BufferedWriter, io.BufferedRWPair, and

2615
Lars Gustäbel42e00912009-03-22 20:34:29 +00002616- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
2617 forever on incomplete input. That caused tarfile.open() to hang when used
2618 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
2619 partial bzip2 compressed data.

Mark Dickinsonb40b9472009-03-29 16:58:21 +00002640 struct.error instead of returning b'\xff\xff\xff\xff'. The
2641 _PY_STRUCT_RANGE_CHECKING and _PY_STRUCT_OVERFLOW_MASKING constants

2665
Antoine Pitrou79eee6b2009-02-13 14:01:05 +00002666- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
2667 rotating the object pointer by 4 bits to the right.
2668
Mark Dickinson87ec0852009-02-09 17:15:59 +00002669- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
2670 it now forces its argument to double before testing for infinity.
2671
Benjamin Petersonee1ae7c2009-02-08 21:07:20 +00002672- Issue #5137: Make len() correctly raise a TypeError when a __len__ method
2673 returns a non-number type.
2674
Benjamin Peterson87618552009-02-08 15:00:52 +00002675- Issue #5182: Removed memoryview.__str__.

2680 to tp_reserved, and is reserved for future usage.
Mark Dickinsonf02e0aa2009-02-01 12:13:56 +00002681
Georg Brandl1cdd83c2009-04-05 20:24:29 +00002682- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingere8364232009-02-02 22:55:09 +00002683 were suppressing all exceptions. These include list() and bytearray().
2684
Mark Dickinson1124e712009-01-28 21:25:58 +00002685- Issue #4707: round(x, n) now returns an integer if x is an integer.
2686 Previously it returned a float.
2687
Antoine Pitroub52ec782009-01-25 16:34:23 +00002688- Issue #4753: By enabling a configure option named '--with-computed-gotos'
2689 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
2690 evaluation loop is compiled with a new dispatch mechanism which gives
2691 speedups of up to 20%, depending on the system, on various benchmarks.
2692
Antoine Pitrou81fabdb2009-01-22 10:11:36 +00002693- Issue #4874: Most builtin decoders now reject unicode input.

2699
Antoine Pitroue4bc7f62009-01-17 21:06:43 +00002700- Issue #4838: When a module is deallocated, free the memory backing the
2701 optional module state data.
2702
Mark Dickinson8055afd2009-01-17 10:04:45 +00002703- Issue #4910: Rename nb_long slot to nb_reserved, and change its
2704 type to (void *).
2705
Antoine Pitrou8d4e5052009-01-13 22:59:11 +00002706- Issue #4935: The overflow checking code in the expandtabs() method common
2707 to str, bytes and bytearray could be optimized away by the compiler, letting
2708 the interpreter segfault instead of raising an error.
2709
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +00002710- Issue #3720: Fix a crash when an iterator modifies its class and removes its
2711 __next__ method.
2712
Mark Dickinsone5e298f2009-01-12 20:49:19 +00002713- Issue #4910: Builtin int() function and PyNumber_Long/PyNumber_Int API
2714 function no longer attempt to call the __long__ slot to convert an object
2715 to an integer. Only the __int__ and __trunc__ slots are examined.
2716
Martin v. Löwis7c2b66c2009-01-12 08:21:03 +00002717- Issue #4893: Use NT threading on CE.
2718
Martin v. Löwisec59d042009-01-12 07:59:10 +00002719- Issue #4915: Port sysmodule to Windows CE.
2720
Antoine Pitrouab868312009-01-10 15:40:25 +00002721- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
2722 common cases are optimized thanks to a dedicated fast path and a moderate
2723 amount of loop unrolling.
2724
Antoine Pitrou14b78f52009-01-09 22:27:08 +00002725- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
2726 collecting the oldest generation) so that allocating lots of objects without
2727 destroying them does not show quadratic performance. Based on a proposal by
2728 Martin von Löwis at
2729 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
2730
Vinay Sajip6268cbc2009-01-21 00:19:28 +00002731- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +00002732 having been closed (for instance, a read() call could return some
2733 previously buffered data). Patch by Dmitry Vasiliev.
2734
Antoine Pitrou05608432009-01-09 18:53:14 +00002735- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
2736 flag to work properly. Furthermore, when specifying -u, the text stdout
2737 and stderr streams have line-by-line buffering enabled (the default being
2738 to buffer arbitrary chunks of data).
2739
Raymond Hettinger35631532009-01-09 03:58:09 +00002740- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
2741 instead of ints (reducing its size from 4 to 8 times thereby reducing
2742 Python's overall memory).
2743
Antoine Pitroud35cbf62009-01-06 19:02:24 +00002744- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
2745 an existing .py counterpart, override the co_filename attributes of all
2746 code objects if the original filename is obsolete (which can happen if the
2747 file has been renamed, moved, or if it is accessed through different paths).
2748 Patch by Ziga Seilnacht and Jean-Paul Calderone.
2749
Antoine Pitrouc3b39242009-01-03 16:59:18 +00002750- Issue #4580: Fix slicing of memoryviews when the item size is greater than
2751 one byte. Also fixes the meaning of len() so that it returns the number of
2752 items, rather than the size in bytes.
2753
Martin v. Löwis5c88d812009-01-02 20:47:48 +00002754- Issue #4075: Use OutputDebugStringW in Py_FatalError.
2755
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +00002756- Issue #4747: When the terminal does not use utf-8, executing a script with
2757 non-ascii characters in its name could fail with a "SyntaxError: None" error.
2758
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002759- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
Hirokazu Yamamoto8ed9a802009-01-01 16:09:52 +00002760 file with `bytes' filename on Windows.
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +00002761
Antoine Pitrou7ddda782009-01-01 15:35:33 +00002762- Issue #3680: Reference cycles created through a dict, set or deque iterator
2763 did not get collected.
2764
Nick Coghlanf1f2f682008-12-30 07:29:12 +00002765- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
2766 where the tp_hash and tp_dict slots are both NULL.
2767
Georg Brandlccc47b62008-12-28 11:44:14 +00002768- Issue #4759: None is now allowed as the first argument of
2769 bytearray.translate(). It was always allowed for bytes.translate().
2770
Skip Montanaro80072cb2008-12-23 03:51:14 +00002771- Added test case to ensure attempts to read from a file opened for writing
2772 fail.
2773
Antoine Pitrou51f3ef92008-12-20 13:14:23 +00002774- Issue #3106: Speedup some comparisons (str/str and int/int).

Antoine Pitrouf289ae62008-12-18 11:06:25 +00002776- Issue #2183: Simplify and optimize bytecode for list, dict and set
2777 comprehensions. Original patch for list comprehensions by Neal Norwitz.
2778
Antoine Pitrou621601a2008-12-17 23:18:19 +00002779- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
2780 print elapsed times, not only when some objects are uncollectable /
2781 unreachable. Original patch by Neil Schemenauer.
2782
Mark Dickinson54bc1ec2008-12-17 16:19:07 +00002783- Issue #3439: Add a bit_length method to int.
2784
Mark Dickinsonda2706b2008-12-11 18:03:03 +00002785- Issue #2173: When getting device encoding, check that return value of
2786 nl_langinfo is not the empty string. This was causing silent build
2787 failures on OS X.
2788
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +00002789- Issue #4597: Fixed several opcodes that weren't always propagating
2790 exceptions.
2791
2792- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +00002793 context manager returns a value that cannot be converted to a bool.
2794
Mark Dickinsonfd24b322008-12-06 15:33:31 +00002795- Issue #4445: Replace "sizeof(PyBytesObject)" with
2796 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
2797 bytes instances. On a typical machine this saves 3 bytes of memory
2798 (on average) per allocation of a bytes instance.
2799
Christian Heimesa872de52008-12-05 08:26:55 +00002800- Issue #4533: File read operation was dreadfully slow due to a slowly
2801 growing read buffer. Fixed by using the same growth rate algorithm as
2802 Python 2.x.
2803
Antoine Pitrou5504e892008-12-06 21:27:53 +00002804- Issue #4509: Various issues surrounding resize of bytearray objects to
2805 which there are buffer exports (e.g. memoryview instances).
2806
Georg Brandlf9734072008-12-07 15:30:06 +00002807- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
2808 method on file objects with closefd=False. The file descriptor is still
2809 kept open but the file object behaves like a closed file. The ``FileIO``
2810 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +00002811
Antoine Pitroubc420402008-12-07 20:14:49 +00002812- Issue #4569: Interpreter crash when mutating a memoryview with an item size

2818
Walter Dörwaldc1651a02009-05-03 22:55:55 +00002819- Issue #5108: Handle %s like %S, %R and %A in PyUnicode_FromFormatV(): Call
2820 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2821 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2822 of using the replace error handler in PyUnicode_DecodeUTF8().
