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.
100
Nick Coghlan47384702009-04-22 16:13:36 +0000101Tests
102-----
103
104- Issue #5354: New test support function import_fresh_module() makes
105 it easy to import both normal and optimised versions of modules.
106 test_heapq and test_warnings have been adjusted to use it, tests for
107 other modules with both C and Python implementations in the stdlib
108 can be adjusted to use it over time.

Benjamin Peterson8f76b492009-04-03 22:22:42 +0000122- Issue #5666: Py_BuildValue's 'c' code should create byte strings.
123
Benjamin Peterson7fe98532009-04-02 00:33:55 +0000124- Issue #5499: The 'c' code for argument parsing functions now only accepts a
125 byte, and the 'C' code only accepts a unicode character.
126
Georg Brandl406b3d82009-04-11 21:24:37 +0000127- Fix a problem in PyErr_NormalizeException that leads to "undetected errors"
128 when hitting the recursion limit under certain circumstances.
129

131
Georg Brandlab6f2f62009-03-31 04:16:10 +0000132- Fix a segfault when running test_exceptions with coverage, caused by
133 insufficient checks in accessors of Exception.__context__.
134
Guido van Rossum0ad59d42009-03-30 22:01:35 +0000135- Issue #5604: non-ASCII characters in module name passed to
136 imp.find_module() were converted to UTF-8 while the path is
137 converted to the default filesystem encoding, causing nonsense.
138

Ronald Oussorenfa1fcd12009-03-30 23:16:10 +0000141- Issue #4865: On MacOSX /Library/Python/2.7/site-packages is added to
142 the end sys.path, for compatibility with the system install of Python.
143
Antoine Pitrou3a652b12009-03-23 18:52:06 +0000144- Issue #4688: Add a heuristic so that tuples and dicts containing only
145 untrackable objects are not tracked by the garbage collector. This can
146 reduce the size of collections and therefore the garbage collection overhead
147 on long-running programs, depending on their particular use of datatypes.
148
Mark Dickinson17e4fdd2009-03-23 18:44:57 +0000149- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

154 2**15 for the internal representation of integers, for performance
155 reasons. Base 2**30 is enabled by default on 64-bit machines. Add

157 default. Add sys.int_info structseq to provide information about
158 the internal format.
159
Mark Dickinson081dfee2009-03-18 14:47:41 +0000160- Issue #4474: PyUnicode_FromWideChar now converts characters outside
161 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
162 and sizeof(Py_UNICODE) == 2.
163
Eric Smith8ec90442009-03-14 12:29:34 +0000164- Issue #5237: Allow auto-numbered fields in str.format(). For
165 example: '{} {}'.format(1, 2) == '1 2'.
166
Antoine Pitrou652e7072009-03-13 19:25:20 +0000167- Issue #5392: when a very low recursion limit was set, the interpreter would
168 abort with a fatal error after the recursion limit was hit twice.
169
Matthias Klose042f1332009-04-04 14:32:42 +0000170- Issue #3845: In PyRun_SimpleFileExFlags avoid invalid memory access with

216
Lars Gustäbel42e00912009-03-22 20:34:29 +0000217- Issue #5068: Fixed the tarfile._BZ2Proxy.read() method that would loop
218 forever on incomplete input. That caused tarfile.open() to hang when used
219 with mode 'r' or 'r:bz2' and a fileobj argument that contained no data or
220 partial bzip2 compressed data.
221
Mark Dickinson79f52032009-03-17 23:12:51 +0000222- Issue #2110: Add support for thousands separator and 'n' type

321
Antoine Pitrouab868312009-01-10 15:40:25 +0000322- Issue #4868: utf-8, utf-16 and latin1 decoding are now 2x to 4x faster. The
323 common cases are optimized thanks to a dedicated fast path and a moderate
324 amount of loop unrolling.
325
Antoine Pitrou14b78f52009-01-09 22:27:08 +0000326- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
327 collecting the oldest generation) so that allocating lots of objects without
328 destroying them does not show quadratic performance. Based on a proposal by
329 Martin von Löwis at
330 http://mail.python.org/pipermail/python-dev/2008-June/080579.html.
331
Vinay Sajip6268cbc2009-01-21 00:19:28 +0000332- Issue #4604: Some objects of the I/O library could still be used after
Antoine Pitrou8043cf82009-01-09 19:54:29 +0000333 having been closed (for instance, a read() call could return some
334 previously buffered data). Patch by Dmitry Vasiliev.
335
Antoine Pitrou05608432009-01-09 18:53:14 +0000336- Issue #4705: Fix the -u ("unbuffered binary stdout and stderr") command-line
337 flag to work properly. Furthermore, when specifying -u, the text stdout
338 and stderr streams have line-by-line buffering enabled (the default being
339 to buffer arbitrary chunks of data).
340
Raymond Hettinger35631532009-01-09 03:58:09 +0000341- The internal table, _PyLong_DigitValue, is now an array of unsigned chars
342 instead of ints (reducing its size from 4 to 8 times thereby reducing
343 Python's overall memory).
344
Antoine Pitroud35cbf62009-01-06 19:02:24 +0000345- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
346 an existing .py counterpart, override the co_filename attributes of all
347 code objects if the original filename is obsolete (which can happen if the
348 file has been renamed, moved, or if it is accessed through different paths).
349 Patch by Ziga Seilnacht and Jean-Paul Calderone.
350
Antoine Pitrouc3b39242009-01-03 16:59:18 +0000351- Issue #4580: Fix slicing of memoryviews when the item size is greater than
352 one byte. Also fixes the meaning of len() so that it returns the number of
353 items, rather than the size in bytes.
354
Martin v. Löwis5c88d812009-01-02 20:47:48 +0000355- Issue #4075: Use OutputDebugStringW in Py_FatalError.
356
Amaury Forgeot d'Arc374e2202009-01-01 23:05:36 +0000357- Issue #4747: When the terminal does not use utf-8, executing a script with

365
Nick Coghlanf1f2f682008-12-30 07:29:12 +0000366- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
367 where the tp_hash and tp_dict slots are both NULL.
368
Georg Brandlccc47b62008-12-28 11:44:14 +0000369- Issue #4759: None is now allowed as the first argument of
370 bytearray.translate(). It was always allowed for bytes.translate().
371
Skip Montanaro80072cb2008-12-23 03:51:14 +0000372- Added test case to ensure attempts to read from a file opened for writing
373 fail.
374

Antoine Pitrouf289ae62008-12-18 11:06:25 +0000377- Issue #2183: Simplify and optimize bytecode for list, dict and set
378 comprehensions. Original patch for list comprehensions by Neal Norwitz.
379
Antoine Pitrou621601a2008-12-17 23:18:19 +0000380- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always
381 print elapsed times, not only when some objects are uncollectable /
382 unreachable. Original patch by Neil Schemenauer.
383
Mark Dickinson54bc1ec2008-12-17 16:19:07 +0000384- Issue #3439: Add a bit_length method to int.
385
Mark Dickinsonda2706b2008-12-11 18:03:03 +0000386- Issue #2173: When getting device encoding, check that return value of

388 failures on OS X.
389
Jeffrey Yasskinb9083f32008-12-11 06:18:33 +0000390- Issue #4597: Fixed several opcodes that weren't always propagating
391 exceptions.
392
393- Issue #4589: Fixed exception handling when the __exit__ function of a
Amaury Forgeot d'Arc10b24e82008-12-10 23:49:33 +0000394 context manager returns a value that cannot be converted to a bool.
395
Mark Dickinsonfd24b322008-12-06 15:33:31 +0000396- Issue #4445: Replace "sizeof(PyBytesObject)" with
397 "offsetof(PyBytesObject, ob_sval) + 1" when allocating memory for
398 bytes instances. On a typical machine this saves 3 bytes of memory
399 (on average) per allocation of a bytes instance.
400
Christian Heimesa872de52008-12-05 08:26:55 +0000401- Issue #4533: File read operation was dreadfully slow due to a slowly
402 growing read buffer. Fixed by using the same growth rate algorithm as
403 Python 2.x.
404
Antoine Pitrou5504e892008-12-06 21:27:53 +0000405- Issue #4509: Various issues surrounding resize of bytearray objects to
406 which there are buffer exports (e.g. memoryview instances).
407
Georg Brandlf9734072008-12-07 15:30:06 +0000408- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
409 method on file objects with closefd=False. The file descriptor is still
410 kept open but the file object behaves like a closed file. The ``FileIO``
411 object also got a new readonly attribute ``closefd``.
Matthias Klose7e1b8fa2008-11-26 17:22:04 +0000412
Antoine Pitroubc420402008-12-07 20:14:49 +0000413- Issue #4569: Interpreter crash when mutating a memoryview with an item size
414 larger than 1.
415
