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
Eric Smithcc32a112009-04-26 21:35:14 +000015- Issue #5835: Deprecate PyOS_ascii_formatd.
16
Martin v. Löwis71efeb72009-04-26 01:02:07 +000017- Issue #4971: Fix titlecase for characters that are their own
18 titlecase, but not their own uppercase.
19
Benjamin Peterson193152c2009-04-25 01:08:45 +000020- Issue #5283: Setting __class__ in __del__ caused a segfault.
21
Mark Dickinsonad476da2009-04-23 19:14:16 +000022- Issue #5816: complex(repr(z)) now recovers z exactly, even when
23 z involves nans, infs or negative zeros.
24
Mark Dickinson4a16e3a2009-04-23 19:15:48 +000025- Issue #3166: Make int -> float conversions correctly rounded.
Mark Dickinsonc6300392009-04-20 21:38:00 +000026
Mark Dickinsone6a076d2009-04-18 11:48:33 +000027- Issue #1869 (and many duplicates): make round(x, n) correctly
28 rounded for a float x, by using the decimal <-> binary conversions
29 from Python/dtoa.c. As a consequence, (e.g.) round(x, 2) now
30 consistently agrees with format(x, '.2f').
31
Benjamin Petersonae937c02009-04-18 20:54:08 +000032- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
33 some builtin types.
34
Eric Smith0923d1d2009-04-16 20:16:10 +000035- Issue #5772: format(1e100, '<') produces '1e+100', not '1.0e+100'.
36
Eric Smith35e84722009-04-16 20:21:28 +000037- Issue #5515: str.format() type 'n' combined with commas and leading
38 zeros no longer gives odd results with ints and floats.
Eric Smith0923d1d2009-04-16 20:16:10 +000039
40- Implement PEP 378, Format Specifier for Thousands Separator, for
41 floats.
42
Mark Dickinson3370cce2009-04-17 22:40:53 +000043- The str function switches to exponential notation at
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000044 1e11, not 1e12. This avoids printing 13 significant digits in
45 situations where only 12 of them are correct. Example problem
46 value: str(1e11 + 0.5). (This minor issue has existed in 2.x for a
47 long time.)
48
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000049- Issue #1580: On most platforms, use a 'short' float repr: for a
50 finite float x, repr(x) now outputs a string based on the shortest
51 sequence of decimal digits that rounds to x. Previous behaviour was
52 to output 17 significant digits and then strip trailing zeros.
Mark Dickinson3370cce2009-04-17 22:40:53 +000053 Another minor difference is that the new repr switches to
54 exponential notation at 1e16 instead of the previous 1e17; this
55 avoids misleading output in some cases.
Mark Dickinsonb08a53a2009-04-16 19:52:09 +000056
57 There's a new sys attribute sys.float_repr_style, which takes
58 the value 'short' to indicate that we're using short float repr,
59 and 'legacy' if the short float repr isn't available for one
60 reason or another.
61
62 The float repr change involves incorporating David Gay's 'perfect
63 rounding' code into the Python core (it's in Python/dtoa.c). As a
64 secondary consequence, all string-to-float and float-to-string
65 conversions (including all float formatting operations) will be
66 correctly rounded on these platforms.
67
68 See issue 1580 discussions for details of platforms for which
69 this change does not apply.
70
Benjamin Peterson2808d3c2009-04-15 21:34:27 +000071- Issue #5759: float() didn't call __float__ on str subclasses.
72
Georg Brandlabc38772009-04-12 15:51:51 +000073- The string.maketrans() function is deprecated; there is a new static method
74 maketrans() on the bytes and bytearray classes. This removes confusion about
75 the types string.maketrans() is supposed to work with, and mirrors the
76 methods available on the str class.
77
R. David Murraydc6da8a2009-04-09 22:16:43 +000078- Issue #2170: refactored xml.dom.minidom.normalize, increasing both
79 its clarity and its speed.
80
Matthias Klose091c7b12009-04-07 13:24:27 +000081- Issue #1113244: Py_XINCREF, Py_DECREF, Py_XDECREF: Add `do { ... } while (0)'
82 to avoid compiler warnings.
83
Benjamin Peterson0b4915e2009-04-25 21:11:45 +000084Installation
85------------
86
87- Issue #5756: Install idle and pydoc with a 3 suffix.

90-------
91
Thomas Heller34596a92009-04-24 20:50:00 +000092- Issue #3102: All global symbols that the _ctypes extension defines
93 are now prefixed with 'Py' or '_ctypes'.
94
95- Issue #5041: ctypes does now allow pickling wide character.
96
Mark Dickinsond4d95f82009-04-24 14:06:19 +000097- Issue #5812: For the two-argument form of the Fraction constructor,
98 Fraction(m, n), m and n are permitted to be arbitrary Rational
99 instances.
100
Mark Dickinsoncf63f2f2009-04-22 17:50:21 +0000101- Issue #5812: Fraction('1e6') is valid: more generally, any string
102 that's valid for float() is now valid for Fraction(), with the
103 exception of strings representing NaNs and infinities.
104
Antoine Pitroucf4c7492009-04-19 00:09:36 +0000105- Issue #5734: BufferedRWPair was poorly tested and had several glaring
106 bugs. Patch by Brian Quinlan.
107
R. David Murray9e94ddf2009-04-13 17:06:33 +0000108- Issue #1161031: fix readwrite select flag handling: POLLPRI now
109 results in a handle_expt_event call, not handle_read_event, and POLLERR
110 and POLLNVAL now call handle_close, not handle_expt_event. Also,
111 dispatcher now has an 'ignore_log_types' attribute for suppressing
112 log messages, which is set to 'warning' by default.
113
Matthias Klosea3d29e82009-04-07 13:13:10 +0000114- Issue #2703: SimpleXMLRPCDispatcher.__init__: Provide default values for
115 new arguments introduced in 2.5.
116
Walter Dörwald1b08b302009-04-25 14:13:56 +0000117- Issue #5828 (Invalid behavior of unicode.lower): Fixed bogus logic in
118 makeunicodedata.py and regenerated the Unicode database (This fixes
119 u'\u1d79'.lower() == '\x00').
120

122-----------------
123
Mark Dickinsonea835e72009-04-19 20:40:33 +0000124- Issue #5463: In struct module, remove deprecated float coercion
125 for integer type codes: struct.pack('L', 0.3) should now raise
126 an error. The _PY_STRUCT_FLOAT_COERCE constant has been removed.
127 The version number has been bumped to 0.3.
128
Matthias Klose535336f2009-04-07 13:49:45 +0000129- Issue #5359: Readd the Berkley-DB detection code to allow _dbm be built
130 using Berkley-DB.
131
Nick Coghlan47384702009-04-22 16:13:36 +0000132Tests
133-----
134
135- Issue #5354: New test support function import_fresh_module() makes
136 it easy to import both normal and optimised versions of modules.
137 test_heapq and test_warnings have been adjusted to use it, tests for
138 other modules with both C and Python implementations in the stdlib
139 can be adjusted to use it over time.
140
Walter Dörwald4ba80132009-04-25 12:48:43 +0000141- Issue #5837: Certain sequences of calls to set() and unset() for
142 support.EnvironmentVarGuard objects restored the environment variables
143 incorrectly on __exit__.

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000157- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
158
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000159- Issue #5499: The 'c' code for argument parsing functions now only accepts a
160 byte, and the 'C' code only accepts a unicode character.

168 insufficient checks in accessors of Exception.__context__.
169
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000170- Issue #5604: non-ASCII characters in module name passed to
171 imp.find_module() were converted to UTF-8 while the path is

177 the end sys.path, for compatibility with the system install of Python.
178
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000179- Issue #4688: Add a heuristic so that tuples and dicts containing only
180 untrackable objects are not tracked by the garbage collector. This can
181 reduce the size of collections and therefore the garbage collection overhead
182 on long-running programs, depending on their particular use of datatypes.
183
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000184- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

189 2**15 for the internal representation of integers, for performance
190 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
191 --enable-big-digits option to configure, which overrides the
192 default. Add sys.int_info structseq to provide information about
193 the internal format.
194
Mark Dickinson081dfee2009-03-18 14:47:41 +0000195- Issue #4474: PyUnicode_FromWideChar now converts characters outside
196 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
197 and sizeof(Py_UNICODE) == 2.
198
Eric Smith8ec90442009-03-14 12:29:34 +0000199- Issue #5237: Allow auto-numbered fields in str.format(). For
200 example: '{} {}'.format(1, 2) == '1 2'.
201
Antoine Pitrou652e7072009-03-13 19:25:20 +0000202- Issue #5392: when a very low recursion limit was set, the interpreter would
203 abort with a fatal error after the recursion limit was hit twice.
204
Matthias Klose042f1332009-04-04 14:32:42 +0000205- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

Brett Cannon7f6b4f82009-03-30 21:30:26 +0000237- Issue #5236: Change time.strptime() to only take strings. Didn't work with
238 bytes already but the failure was non-obvious.
239
Jesse Noller7af4ef82009-03-30 16:47:15 +0000240- Issue #5177: Multiprocessing's SocketListener class now uses

243
Benjamin Peterson48e24782009-03-29 13:02:52 +0000244- Issue #5595: Fix UnboundedLocalError in ntpath.ismount().

254 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
255 partial bzip2 compressed data.
256
Mark Dickinson79f52032009-03-17 23:12:51 +0000257- Issue #2110: Add support for thousands separator and 'n' type

Mark Dickinson1124e712009-01-28 21:25:58 +0000321- Issue #4707: round(x, n) now returns an integer if x is an integer.
322 Previously it returned a float.
323
Antoine Pitroub52ec782009-01-25 16:34:23 +0000324- Issue #4753: By enabling a configure option named '--with-computed-gotos'
325 on compilers that support it (notably: gcc, SunPro, icc), the bytecode
326 evaluation loop is compiled with a new dispatch mechanism which gives
327 speedups of up to 20%, depending on the system, on various benchmarks.

340 type to (void *).
341
Antoine Pitrou8d4e5052009-01-13 22:59:11 +0000342- Issue #4935: The overflow checking code in the expandtabs() method common
343 to str, bytes and bytearray could be optimized away by the compiler, letting
344 the interpreter segfault instead of raising an error.
345
Amaury Forgeot d'Arcf343e012009-01-12 23:58:21 +0000346- Issue #3720: Fix a crash when an iterator modifies its class and removes its

358 common cases are optimized thanks to a dedicated fast path and a moderate
359 amount of loop unrolling.
360
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000361- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
362 collecting the oldest generation) so that allocating lots of objects without
363 destroying them does not show quadratic performance. Based on a proposal by
364 Martin von Löwis at
365 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
366
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000367- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000368 having been closed (for instance, a read() call could return some
369 previously buffered data). Patch by Dmitry Vasiliev.
370
Antoine Pitrou05608432009-01-09 18:53:14 +0000371- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
372 flag to work properly. Furthermore, when specifying -u, the text stdout
373 and stderr streams have line-by-line buffering enabled (the default being
374 to buffer arbitrary chunks of data).
375
Raymond Hettinger35631532009-01-09 03:58:09 +0000376- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
377 instead of ints (reducing its size from 4 to 8 times thereby reducing
378 Python's overall memory).
379
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000380- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
381 an existing .py counterpart, override the co_filename attributes of all
382 code objects if the original filename is obsolete (which can happen if the
383 file has been renamed, moved, or if it is accessed through different paths).
384 Patch by Ziga Seilnacht and Jean-Paul Calderone.
385
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000386- Issue #4580: Fix slicing of memoryviews when the item size is greater than
387 one byte. Also fixes the meaning of len() so that it returns the number of
388 items, rather than the size in bytes.
389
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000390- Issue #4075: Use OutputDebugStringW in Py_FatalError.
391
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000392- Issue #4747: When the terminal does not use utf-8, executing a script with
393 non-ascii characters in its name could fail with a "SyntaxError: None" error.
394
Hirokazu Yamamoto0f22d692009-01-01 16:03:45 +0000395- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open

400
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000401- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
402 where the tp_hash and tp_dict slots are both NULL.
403
Georg Brandlccc47b62008-12-28 11:44:14 +0000404- Issue #4759: None is now allowed as the first argument of
405 bytearray.translate(). It was always allowed for bytes.translate().
406
Skip Montanaro80072cb2008-12-23 03:51:14 +0000407- Added test case to ensure attempts to read from a file opened for writing
408 fail.

414
Antoine Pitrou621601a2008-12-17 23:18:19 +0000415- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

417 unreachable. Original patch by Neil Schemenauer.
418
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000419- Issue #3439: Add a bit_length method to int.

423 failures on OS X.
424
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000425- Issue #4597: Fixed several opcodes that weren't always propagating

427
428- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000429 context manager returns a value that cannot be converted to a bool.
430
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000431- Issue #4445: Replace "sizeof(PyBytesObject)" with
432 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
433 bytes instances. On a typical machine this saves 3 bytes of memory
434 (on average) per allocation of a bytes instance.
435
Christian Heimesa872de52008-12-05 08:26:55 +0000436- Issue #4533: File read operation was dreadfully slow due to a slowly

438 Python 2.x.
439
Antoine Pitrou5504e892008-12-06 21:27:53 +0000440- Issue #4509: Various issues surrounding resize of bytearray objects to
441 which there are buffer exports (e.g. memoryview instances).
442
Georg Brandlf9734072008-12-07 15:30:06 +0000443- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
444 method on file objects with closefd=False. The file descriptor is still
445 kept open but the file object behaves like a closed file. The ``FileIO``
446 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000447
Antoine Pitroubc420402008-12-07 20:14:49 +0000448- Issue #4569: Interpreter crash when mutating a memoryview with an item size
