Benjamin Petersonbd35b032009-04-04 23:16:41 +00007What's New in Python 3.1 beta 1?
8================================
9
10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000015- The repr function switches to exponential notation at 1e16, not 1e17
16 as it did before. This change applies to both 'short' and legacy
17 float repr styles. For the new repr style, it avoids misleading
18 output in some cases: an example is repr(2e16+8), which gives
19 '2.000000000000001e+16'; without this change it would have produced
20 '20000000000000010.0' instead.
21
22- Similarly, the str function switches to exponential notation at
23 1e11, not 1e12. This avoids printing 13 significant digits in
24 situations where only 12 of them are correct. Example problem
25 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
26 long time.)
27
28- On x86, SSE2 instructions for floating-point are automatically
29 detected and, where possible, enabled on platforms using the gcc
30 compiler. As a consequence, some arithmetic operations may have
31 different (more accurate!) results on some platforms, and
32 cross-platform consistency of Python arithmetic should be improved.
33 This applies particularly to Linux/x86.
34
35- Issue #1580: On most platforms, use a 'short' float repr: for a
36 finite float x, repr(x) now outputs a string based on the shortest
37 sequence of decimal digits that rounds to x. Previous behaviour was
38 to output 17 significant digits and then strip trailing zeros.
39
40 There's a new sys attribute sys.float_repr_style, which takes
41 the value 'short' to indicate that we're using short float repr,
42 and 'legacy' if the short float repr isn't available for one
43 reason or another.
44
45 The float repr change involves incorporating David Gay's 'perfect
46 rounding' code into the Python core (it's in Python/dtoa.c). As a
47 secondary consequence, all string-to-float and float-to-string
48 conversions (including all float formatting operations) will be
49 correctly rounded on these platforms.
50
51 See issue 1580 discussions for details of platforms for which
52 this change does not apply.
53
Benjamin Peterson2808d3c2009-04-15 21:34:27 +000054- Issue #5759: float() didn't call __float__ on str subclasses.
55
Georg Brandlabc38772009-04-12 15:51:51 +000056- The string.maketrans() function is deprecated; there is a new static method
57 maketrans() on the bytes and bytearray classes. This removes confusion about
58 the types string.maketrans() is supposed to work with, and mirrors the
59 methods available on the str class.
60
R. David Murraydc6da8a2009-04-09 22:16:43 +000061- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
62 its clarity and its speed.
63
Matthias Klose091c7b12009-04-07 13:24:27 +000064- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
65 to avoid compiler warnings.

68-------
69
R. David Murray9e94ddf2009-04-13 17:06:33 +000070- Issue #1161031: fix readwrite select flag handling: POLLPRI now
71 results in a handle_expt_event call, not handle_read_event, and POLLERR
72 and POLLNVAL now call handle_close, not handle_expt_event. Also,
73 dispatcher now has an 'ignore_log_types' attribute for suppressing
74 log messages, which is set to 'warning' by default.
75
Matthias Klosea3d29e82009-04-07 13:13:10 +000076- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
77 new arguments introduced in 2.5.

95 integers.
Benjamin Petersond1735892009-03-07 18:46:21 +000096
Benjamin Peterson8f76b492009-04-03 22:22:42 +000097- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
98
Benjamin Peterson7fe98532009-04-02 00:33:55 +000099- Issue #5499: The 'c' code for argument parsing functions now only accepts a
100 byte, and the 'C' code only accepts a unicode character.
101
Georg Brandl406b3d82009-04-11 21:24:37 +0000102- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
103 when hitting the recursion limit under certain circumstances.

108 insufficient checks in accessors of Exception.__context__.
109
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000110- Issue #5604: non-ASCII characters in module name passed to
111 imp.find_module() were converted to UTF-8 while the path is
112 converted to the default filesystem encoding, causing nonsense.
113
Benjamin Peterson09832742009-03-26 17:15:46 +0000114- Issue #5126: str.isprintable() returned False for space characters.

118
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000119- Issue #4688: Add a heuristic so that tuples and dicts containing only
120 untrackable objects are not tracked by the garbage collector. This can
121 reduce the size of collections and therefore the garbage collection overhead
122 on long-running programs, depending on their particular use of datatypes.
123
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000124- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

129 2**15 for the internal representation of integers, for performance
130 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
131 --enable-big-digits option to configure, which overrides the
132 default. Add sys.int_info structseq to provide information about
133 the internal format.
134
Mark Dickinson081dfee2009-03-18 14:47:41 +0000135- Issue #4474: PyUnicode_FromWideChar now converts characters outside
136 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
137 and sizeof(Py_UNICODE) == 2.
138
Eric Smith8ec90442009-03-14 12:29:34 +0000139- Issue #5237: Allow auto-numbered fields in str.format(). For

141
Antoine Pitrou652e7072009-03-13 19:25:20 +0000142- Issue #5392: when a very low recursion limit was set, the interpreter would
143 abort with a fatal error after the recursion limit was hit twice.
144
Matthias Klose042f1332009-04-04 14:32:42 +0000145- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Raymond Hettinger35631532009-01-09 03:58:09 +0000316- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
317 instead of ints (reducing its size from 4 to 8 times thereby reducing
318 Python's overall memory).
319
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000320- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
321 an existing .py counterpart, override the co_filename attributes of all
322 code objects if the original filename is obsolete (which can happen if the
323 file has been renamed, moved, or if it is accessed through different paths).
324 Patch by Ziga Seilnacht and Jean-Paul Calderone.

328 items, rather than the size in bytes.
329
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000330- Issue #4075: Use OutputDebugStringW in Py_FatalError.

370
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000371- Issue #4445: Replace "sizeof(PyBytesObject)" with
372 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

382
Georg Brandlf9734072008-12-07 15:30:06 +0000383- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
384 method on file objects with closefd=False. The file descriptor is still
385 kept open but the file object behaves like a closed file. The ``FileIO``
386 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000387
Antoine Pitroubc420402008-12-07 20:14:49 +0000388- Issue #4569: Interpreter crash when mutating a memoryview with an item size
