Benjamin Petersonbd35b032009-04-04 23:16:41 +00007What's New in Python 3.1 beta 1?
8================================

11
12Core and Builtins
13-----------------
14
Eric Smith0923d1d2009-04-16 20:16:10 +000015- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
16
Eric Smith35e84722009-04-16 20:21:28 +000017- Issue #5515: str.format() type 'n' combined with commas and leading
18 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +000019
20- Implement PEP 378, Format Specifier for Thousands Separator, for
21 floats.
22
Mark Dickinson3370cce2009-04-17 22:40:53 +000023- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000024 1e11, not 1e12. This avoids printing 13 significant digits in
25 situations where only 12 of them are correct. Example problem
26 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
27 long time.)
28
29- On x86, SSE2 instructions for floating-point are automatically
30 detected and, where possible, enabled on platforms using the gcc
31 compiler. As a consequence, some arithmetic operations may have
32 different (more accurate!) results on some platforms, and
33 cross-platform consistency of Python arithmetic should be improved.
34 This applies particularly to Linux/x86.
35
36- Issue #1580: On most platforms, use a 'short' float repr: for a
37 finite float x, repr(x) now outputs a string based on the shortest
38 sequence of decimal digits that rounds to x. Previous behaviour was
39 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +000040 Another minor difference is that the new repr switches to
41 exponential notation at 1e16 instead of the previous 1e17; this
42 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000043
44 There's a new sys attribute sys.float_repr_style, which takes
45 the value 'short' to indicate that we're using short float repr,
46 and 'legacy' if the short float repr isn't available for one
47 reason or another.
48
49 The float repr change involves incorporating David Gay's 'perfect
50 rounding' code into the Python core (it's in Python/dtoa.c). As a
51 secondary consequence, all string-to-float and float-to-string
52 conversions (including all float formatting operations) will be
53 correctly rounded on these platforms.
54
55 See issue 1580 discussions for details of platforms for which
56 this change does not apply.
57
Benjamin Peterson2808d3c2009-04-15 21:34:27 +000058- Issue #5759: float() didn't call __float__ on str subclasses.
59
Georg Brandlabc38772009-04-12 15:51:51 +000060- The string.maketrans() function is deprecated; there is a new static method
61 maketrans() on the bytes and bytearray classes. This removes confusion about
62 the types string.maketrans() is supposed to work with, and mirrors the
63 methods available on the str class.
64
R. David Murraydc6da8a2009-04-09 22:16:43 +000065- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
66 its clarity and its speed.
67
Matthias Klose091c7b12009-04-07 13:24:27 +000068- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
69 to avoid compiler warnings.

73
R. David Murray9e94ddf2009-04-13 17:06:33 +000074- Issue #1161031: fix readwrite select flag handling: POLLPRI now
75 results in a handle_expt_event call, not handle_read_event, and POLLERR
76 and POLLNVAL now call handle_close, not handle_expt_event. Also,
77 dispatcher now has an 'ignore_log_types' attribute for suppressing
78 log messages, which is set to 'warning' by default.
79
Matthias Klosea3d29e82009-04-07 13:13:10 +000080- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
81 new arguments introduced in 2.5.

99 integers.
Benjamin Petersond1735892009-03-07 18:46:21 +0000100
Benjamin Peterson8f76b492009-04-03 22:22:42 +0000101- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
102
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000103- Issue #5499: The 'c' code for argument parsing functions now only accepts a
104 byte, and the 'C' code only accepts a unicode character.
105
Georg Brandl406b3d82009-04-11 21:24:37 +0000106- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"

112 insufficient checks in accessors of Exception.__context__.
113
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000114- Issue #5604: non-ASCII characters in module name passed to
115 imp.find_module() were converted to UTF-8 while the path is
116 converted to the default filesystem encoding, causing nonsense.
117

121 the end sys.path, for compatibility with the system install of Python.
122
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000123- Issue #4688: Add a heuristic so that tuples and dicts containing only
124 untrackable objects are not tracked by the garbage collector. This can
125 reduce the size of collections and therefore the garbage collection overhead
126 on long-running programs, depending on their particular use of datatypes.
127
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000128- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
129 improve its performance. Long divisions and remainder operations
130 are now between 50% and 150% faster.
131
Mark Dickinsonbd792642009-03-18 20:06:12 +0000132- Issue #4258: Make it possible to use base 2**30 instead of base
133 2**15 for the internal representation of integers, for performance
134 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
135 --enable-big-digits option to configure, which overrides the
136 default. Add sys.int_info structseq to provide information about
137 the internal format.
138
Mark Dickinson081dfee2009-03-18 14:47:41 +0000139- Issue #4474: PyUnicode_FromWideChar now converts characters outside
140 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
141 and sizeof(Py_UNICODE) == 2.
142
Eric Smith8ec90442009-03-14 12:29:34 +0000143- Issue #5237: Allow auto-numbered fields in str.format(). For

145
Antoine Pitrou652e7072009-03-13 19:25:20 +0000146- Issue #5392: when a very low recursion limit was set, the interpreter would
147 abort with a fatal error after the recursion limit was hit twice.
148
Matthias Klose042f1332009-04-04 14:32:42 +0000149- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

314
Antoine Pitrou05608432009-01-09 18:53:14 +0000315- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
316 flag to work properly. Furthermore, when specifying -u, the text stdout
317 and stderr streams have line-by-line buffering enabled (the default being
318 to buffer arbitrary chunks of data).
319
Raymond Hettinger35631532009-01-09 03:58:09 +0000320- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
321 instead of ints (reducing its size from 4 to 8 times thereby reducing
322 Python's overall memory).
323
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000324- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
325 an existing .py counterpart, override the co_filename attributes of all
326 code objects if the original filename is obsolete (which can happen if the
327 file has been renamed, moved, or if it is accessed through different paths).
328 Patch by Ziga Seilnacht and Jean-Paul Calderone.
329

331 one byte. Also fixes the meaning of len() so that it returns the number of
332 items, rather than the size in bytes.
333
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000334- Issue #4075: Use OutputDebugStringW in Py_FatalError.

347
Georg Brandlccc47b62008-12-28 11:44:14 +0000348- Issue #4759: None is now allowed as the first argument of

350
Skip Montanaro80072cb2008-12-23 03:51:14 +0000351- Added test case to ensure attempts to read from a file opened for writing
352 fail.

374
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000375- Issue #4445: Replace "sizeof(PyBytesObject)" with
376 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for

379
Christian Heimesa872de52008-12-05 08:26:55 +0000380- Issue #4533: File read operation was dreadfully slow due to a slowly

385 which there are buffer exports (e.g. memoryview instances).
386
Georg Brandlf9734072008-12-07 15:30:06 +0000387- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
388 method on file objects with closefd=False. The file descriptor is still
389 kept open but the file object behaves like a closed file. The ``FileIO``
390 object also got a new readonly attribute ``closefd``.
