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 Dickinsonc6300392009-04-20 21:38:00 +000015- Issue #3166: Make long -> float (and int -> float) conversions
16 correctly rounded.
17
Mark Dickinsone6a076d2009-04-18 11:48:33 +000018- Issue #1869 (and many duplicates): make round(x, n) correctly
19 rounded for a float x, by using the decimal <-> binary conversions
20 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
21 consistently agrees with format(x, '.2f').
22
Benjamin Petersonae937c02009-04-18 20:54:08 +000023- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
24 some builtin types.
25
Eric Smith0923d1d2009-04-16 20:16:10 +000026- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
27
Eric Smith35e84722009-04-16 20:21:28 +000028- Issue #5515: str.format() type 'n' combined with commas and leading
29 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +000030
31- Implement PEP 378, Format Specifier for Thousands Separator, for
32 floats.
33
Mark Dickinson3370cce2009-04-17 22:40:53 +000034- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000035 1e11, not 1e12. This avoids printing 13 significant digits in
36 situations where only 12 of them are correct. Example problem
37 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
38 long time.)
39
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000040- Issue #1580: On most platforms, use a 'short' float repr: for a
41 finite float x, repr(x) now outputs a string based on the shortest
42 sequence of decimal digits that rounds to x. Previous behaviour was
43 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +000044 Another minor difference is that the new repr switches to
45 exponential notation at 1e16 instead of the previous 1e17; this
46 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000047
48 There's a new sys attribute sys.float_repr_style, which takes
49 the value 'short' to indicate that we're using short float repr,
50 and 'legacy' if the short float repr isn't available for one
51 reason or another.
52
53 The float repr change involves incorporating David Gay's 'perfect
54 rounding' code into the Python core (it's in Python/dtoa.c). As a
55 secondary consequence, all string-to-float and float-to-string
56 conversions (including all float formatting operations) will be
57 correctly rounded on these platforms.
58
59 See issue 1580 discussions for details of platforms for which
60 this change does not apply.
61
Benjamin Peterson2808d3c2009-04-15 21:34:27 +000062- Issue #5759: float() didn't call __float__ on str subclasses.
63
Georg Brandlabc38772009-04-12 15:51:51 +000064- The string.maketrans() function is deprecated; there is a new static method
65 maketrans() on the bytes and bytearray classes. This removes confusion about
66 the types string.maketrans() is supposed to work with, and mirrors the
67 methods available on the str class.
68
R. David Murraydc6da8a2009-04-09 22:16:43 +000069- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
70 its clarity and its speed.
71
Matthias Klose091c7b12009-04-07 13:24:27 +000072- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
73 to avoid compiler warnings.
74
Benjamin Petersonbd35b032009-04-04 23:16:41 +000075Library
76-------
77
Antoine Pitroucf4c7492009-04-19 00:09:36 +000078- Issue #5734: BufferedRWPair was poorly tested and had several glaring
79 bugs. Patch by Brian Quinlan.
80
R. David Murray9e94ddf2009-04-13 17:06:33 +000081- Issue #1161031: fix readwrite select flag handling: POLLPRI now
82 results in a handle_expt_event call, not handle_read_event, and POLLERR
83 and POLLNVAL now call handle_close, not handle_expt_event. Also,
84 dispatcher now has an 'ignore_log_types' attribute for suppressing
85 log messages, which is set to 'warning' by default.
86
Matthias Klosea3d29e82009-04-07 13:13:10 +000087- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
88 new arguments introduced in 2.5.
89

91-----------------
92
Mark Dickinsonea835e72009-04-19 20:40:33 +000093- Issue #5463: In struct module, remove deprecated float coercion
94 for integer type codes: struct.pack('L', 0.3) should now raise
95 an error. The _PY_STRUCT_FLOAT_COERCE constant has been removed.
96 The version number has been bumped to 0.3.
97
Matthias Klose535336f2009-04-07 13:49:45 +000098- Issue #5359: Readd the Berkley-DB detection code to allow _dbm be built
99 using Berkley-DB.

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000113- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
114
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000115- Issue #5499: The 'c' code for argument parsing functions now only accepts a

122
Georg Brandlab6f2f62009-03-31 04:16:10 +0000123- Fix a segfault when running test_exceptions with coverage, caused by
124 insufficient checks in accessors of Exception.__context__.
125
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000126- Issue #5604: non-ASCII characters in module name passed to
127 imp.find_module() were converted to UTF-8 while the path is
128 converted to the default filesystem encoding, causing nonsense.

133 the end sys.path, for compatibility with the system install of Python.
134
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000135- Issue #4688: Add a heuristic so that tuples and dicts containing only
136 untrackable objects are not tracked by the garbage collector. This can
137 reduce the size of collections and therefore the garbage collection overhead
138 on long-running programs, depending on their particular use of datatypes.
139
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000140- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
141 improve its performance. Long divisions and remainder operations
142 are now between 50% and 150% faster.
143
Mark Dickinsonbd792642009-03-18 20:06:12 +0000144- Issue #4258: Make it possible to use base 2**30 instead of base
145 2**15 for the internal representation of integers, for performance
146 reasons. Base 2**30 is enabled by default on 64-bit machines. Add

Mark Dickinson081dfee2009-03-18 14:47:41 +0000151- Issue #4474: PyUnicode_FromWideChar now converts characters outside
152 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
153 and sizeof(Py_UNICODE) == 2.
154
Eric Smith8ec90442009-03-14 12:29:34 +0000155- Issue #5237: Allow auto-numbered fields in str.format(). For
156 example: '{} {}'.format(1, 2) == '1 2'.
157
Antoine Pitrou652e7072009-03-13 19:25:20 +0000158- Issue #5392: when a very low recursion limit was set, the interpreter would
159 abort with a fatal error after the recursion limit was hit twice.
160
Matthias Klose042f1332009-04-04 14:32:42 +0000161- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

312
Antoine Pitrouab868312009-01-10 15:40:25 +0000313- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
314 common cases are optimized thanks to a dedicated fast path and a moderate
315 amount of loop unrolling.
316
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000317- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
318 collecting the oldest generation) so that allocating lots of objects without
319 destroying them does not show quadratic performance. Based on a proposal by
320 Martin von Löwis at
321 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
322
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000323- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000324 having been closed (for instance, a read() call could return some
325 previously buffered data). Patch by Dmitry Vasiliev.
326
Antoine Pitrou05608432009-01-09 18:53:14 +0000327- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
328 flag to work properly. Furthermore, when specifying -u, the text stdout
329 and stderr streams have line-by-line buffering enabled (the default being
330 to buffer arbitrary chunks of data).
331
Raymond Hettinger35631532009-01-09 03:58:09 +0000332- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
333 instead of ints (reducing its size from 4 to 8 times thereby reducing
334 Python's overall memory).
335
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000336- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
337 an existing .py counterpart, override the co_filename attributes of all
338 code objects if the original filename is obsolete (which can happen if the
339 file has been renamed, moved, or if it is accessed through different paths).
340 Patch by Ziga Seilnacht and Jean-Paul Calderone.
341
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000342- Issue #4580: Fix slicing of memoryviews when the item size is greater than
343 one byte. Also fixes the meaning of len() so that it returns the number of
344 items, rather than the size in bytes.
345
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000346- Issue #4075: Use OutputDebugStringW in Py_FatalError.
347
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000348- Issue #4747: When the terminal does not use utf-8, executing a script with
349 non-ascii characters in its name could fail with a "SyntaxError: None" error.
350
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000351- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

355 did not get collected.
356
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000357- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
358 where the tp_hash and tp_dict slots are both NULL.
359
Georg Brandlccc47b62008-12-28 11:44:14 +0000360- Issue #4759: None is now allowed as the first argument of
361 bytearray.translate(). It was always allowed for bytes.translate().
362
Skip Montanaro80072cb2008-12-23 03:51:14 +0000363- Added test case to ensure attempts to read from a file opened for writing
364 fail.
365

Antoine Pitrouf289ae62008-12-18 11:06:25 +0000368- Issue #2183: Simplify and optimize bytecode for list, dict and set
369 comprehensions. Original patch for list comprehensions by Neal Norwitz.
370
Antoine Pitrou621601a2008-12-17 23:18:19 +0000371- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
372 print elapsed times, not only when some objects are uncollectable /
373 unreachable. Original patch by Neil Schemenauer.
374
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000375- Issue #3439: Add a bit_length method to int.

379 failures on OS X.
380
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000381- Issue #4597: Fixed several opcodes that weren't always propagating
382 exceptions.
383
384- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000385 context manager returns a value that cannot be converted to a bool.
386
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000387- Issue #4445: Replace "sizeof(PyBytesObject)" with
388 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
389 bytes instances. On a typical machine this saves 3 bytes of memory
390 (on average) per allocation of a bytes instance.
391
Christian Heimesa872de52008-12-05 08:26:55 +0000392- Issue #4533: File read operation was dreadfully slow due to a slowly
393 growing read buffer. Fixed by using the same growth rate algorithm as
394 Python 2.x.
395
Antoine Pitrou5504e892008-12-06 21:27:53 +0000396- Issue #4509: Various issues surrounding resize of bytearray objects to
397 which there are buffer exports (e.g. memoryview instances).
398
Georg Brandlf9734072008-12-07 15:30:06 +0000399- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
400 method on file objects with closefd=False. The file descriptor is still
401 kept open but the file object behaves like a closed file. The ``FileIO``
402 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000403
Antoine Pitroubc420402008-12-07 20:14:49 +0000404- Issue #4569: Interpreter crash when mutating a memoryview with an item size
405 larger than 1.
406
