Benjamin Peterson4f51baf2009-12-05 18:40:02 +00007What's New in Python 2.7 alpha 2?
8=================================

10*Release date: XXXX-XX-XX*
11
12Core and Builtins
13-----------------
14
Benjamin Petersonecdae192010-01-04 00:43:01 +000015- The __complex__ method is now looked up on the class of instances to make it
16 consistent with other special methods.
17
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000018- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
19 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
20
Mark Dickinson1b34d252010-01-01 17:27:30 +000021- Issue #5080: A number of functions and methods previously produced a
22 DeprecationWarning when passed a float argument where an integer was
23 expected. These functions and methods now raise TypeError instead.
24 The majority of the effects of this change are in the extension
25 modules, but some core functions and methods are affected: notably
26 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
27 methods.
28
Benjamin Peterson0f02d392009-12-30 19:34:10 +000029- Issue #7604: Deleting an unset slotted attribute did not raise an
30 AttributeError.
31
Mark Dickinson99d652e2009-12-30 12:12:23 +000032- Issue #7534: Fix handling of IEEE specials (infinities, nans,
33 negative zero) in ** operator. The behaviour now conforms to that
34 described in C99 Annex F.
35
Amaury Forgeot d'Arcc8a2ce72009-12-29 23:06:17 +000036- Issue #7579: the msvcrt module now has docstrings for all its functions.
37
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000038- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
39 used to drop the time part of the result.
40
Mark Dickinson46572832009-12-27 14:55:57 +000041- Issue #1811: improve accuracy and cross-platform consistency for
42 true division of integers: the result of a/b is now correctly
43 rounded for ints a and b (at least on IEEE 754 platforms), and in
44 particular does not depend on the internal representation of a long.
45
Ezio Melottif84caf42009-12-24 22:25:17 +000046- Issue #6108: unicode(exception) and str(exception) should return the same
47 message when only __str__ (and not __unicode__) is overridden in the subclass.
48
Ronald Oussoren92919a62009-12-24 13:30:58 +000049- Issue #6834: replace the implementation for the 'python' and 'pythonw'
50 executables on OSX.
51
52 These executables now work properly with the arch(1) command:
53 ``arch -ppc python`` will start a universal binary version of python
54 in PPC mode (unlike previous releases).
55
R. David Murray0a0a1a82009-12-14 16:28:26 +000056- Issue #1680159: unicode coercion during an 'in' operation no longer masks
57 the underlying error when the coercion fails for the left hand operand.
58
Benjamin Peterson4895af42009-12-13 16:36:53 +000059- Issue #7491: Metaclass's __cmp__ method was ignored.
60
Antoine Pitrou2a08b422009-12-13 16:18:14 +000061- Issue #7466: segmentation fault when the garbage collector is called
Antoine Pitrou54584182010-01-07 17:54:10 +000062 in the middle of populating a tuple. Patch by Florent Xicluna.
Antoine Pitrou2a08b422009-12-13 16:18:14 +000063
R. David Murrayc7298ff2009-12-14 21:57:39 +000064

69 gcc when it has a fully qualified configuration prefix. Initial patch
70 by Arfrever.
71
Antoine Pitrou80157252010-01-08 19:20:17 +000072- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
73 renaming of `cPickle` to `pickle`. The warning was annoying since there's
74 no alternative to cPickle if you care about performance. Patch by Florent
75 Xicluna.
76
Antoine Pitrou0d423b82010-01-07 17:46:49 +000077- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by
Antoine Pitrou54584182010-01-07 17:54:10 +000078 Victor Stinner.
Antoine Pitrou0d423b82010-01-07 17:46:49 +000079

81 when using the -3 flag. Patch by Florent Xicluna.
82
Antoine Pitrou673ddf92010-01-03 22:29:56 +000083- Issue #7471: Improve the performance of GzipFile's buffering mechanism,
84 and make it implement the `io.BufferedIOBase` ABC to allow for further
85 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
86
87- Issue #3972: httplib.HTTPConnection now accepts an optional source_address
Gregory P. Smith9d325212010-01-03 02:06:07 +000088 parameter to allow specifying where your connections come from.

Ezio Melotti569e61f2009-12-30 06:14:51 +000096 when building on OSX 10.6 without "-arch" flags.
Ronald Oussorenca8e7ec2009-12-24 14:50:35 +000097

102 the Distutils upload command to avoid an error when PyPI reads it.
103 This occurs on long passwords. Initial patch by JP St. Pierre.
104
105- Issue #7231: urllib2 cannot handle https with proxy requiring auth.
Senthil Kumaran7713acf2009-12-20 06:05:13 +0000106 Patch by Tatsuhiro Tsujikawa.
107
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000108- Issue #7349: Make methods of file objects in the io module accept None as an
109 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
110 the same as passing no argument.
111
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000112- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
113 like other file objects.
114
Lars Gustäbel92ca7562009-12-13 11:32:27 +0000115- Issue #7357: tarfile no longer suppresses fatal extraction errors by
116 default.
117
Vinay Sajip5cc4e2a2009-12-11 09:16:01 +0000118- Issue #7470: logging: fix bug in Unicode encoding fallback.
119
R. David Murray93321f32009-12-09 15:15:31 +0000120- Issue #5949: fixed IMAP4_SSL hang when the IMAP server response is
121 missing proper end-of-line termination.
122
Tarek Ziadé2421d562009-12-20 23:23:34 +0000123- Issue #7457: added a read_pkg_file method to
Tarek Ziadéa939ecd2009-12-08 08:56:49 +0000124 distutils.dist.DistributionMetadata.
Benjamin Peterson4f51baf2009-12-05 18:40:02 +0000125
Gregory P. Smithfe32d302010-01-02 22:42:50 +0000126- Issue #3745: Undo the 2.7a1 change to have hashlib to reject unicode and

131
Mark Dickinson1b34d252010-01-01 17:27:30 +0000132- Issue #5080: The argument parsing functions PyArg_ParseTuple,
133 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
134 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
135 arguments for integer format codes (other than 'L'): previously an
136 attempt to pass a float resulted in a DeprecationWarning; now it
137 gives a TypeError. For the 'L' format code (which previously had no
138 warning) there is now a DeprecationWarning.
139
Georg Brandl740cdc32009-12-28 08:34:58 +0000140- Issue #7033: function ``PyErr_NewExceptionWithDoc()`` added.

Benjamin Peterson6c99b4e2010-01-01 15:20:06 +0000148 --with-system-ffi flag is used.
Benjamin Petersonb4abef62010-01-01 15:18:38 +0000149
Benjamin Peterson2c196742009-12-31 03:17:18 +0000150- Issue #7609: Add a --with-system-expat option that causes the system's expat
151 library to be used for the pyexpat module instead of the one included with
152 Python.
153
Benjamin Peterson500ce232009-12-30 02:58:50 +0000154- Issue #7589: Only build the nis module when the correct header files are

166 with no arguments, doctest.py now gives a usage message.
167
R. David Murray98e3df32009-12-16 11:49:46 +0000168- Issue #7396: fix regrtest -s, which was broken by the -j enhancement.
169
R. David Murrayc7298ff2009-12-14 21:57:39 +0000170- Issue #7498: test_multiprocessing now uses test_support.find_unused_port

180Core and Builtins
181-----------------
182
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000183- Issue #7419: setlocale() could crash the interpreter on Windows when called
184 with invalid values.
185
Eric Smithc4ab8332009-11-29 17:40:57 +0000186- Issue #3382: 'F' formatting for float and complex now convert the
187 result to upper case. This only affects 'inf' and 'nan', since 'f'
188 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000189
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000190- Remove switch from "%f" formatting to "%g" formatting for floats
191 larger than 1e50 in absolute value.
192
Mark Dickinson18cfada2009-11-23 18:46:41 +0000193- Remove restrictions on precision when formatting floats. E.g.,
194 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
195 requested 120 significant digits instead.
196
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000197- Add Py3k warnings for parameter names in parenthesis.
198
Benjamin Peterson48f0a8d2009-11-19 23:19:29 +0000199- Issue #7362: Give a proper error message for def f((x)=3): pass.
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000200
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000201- Issue #7085: Fix crash when importing some extensions in a thread
202 on MacOSX 10.6.
203
Mark Dickinsonb678de82009-11-19 18:41:49 +0000204- Issue #7117: repr(x) for a float x returns a result based on the
205 shortest decimal string that's guaranteed to round back to x under
206 correct rounding (with round-half-to-even rounding mode).
207 Previously it gave a string based on rounding x to 17 decimal digits.
208 repr(x) for a complex number behaves similarly. On platforms where
209 the correctly-rounded strtod and dtoa code is not supported (see below),
210 repr is unchanged.
211
212- Issue #7117: On almost all platforms: float-to-string and
213 string-to-float conversions within Python are now correctly rounded.
214 Places these conversions occur include: str for floats and complex
215 numbers; the float and complex constructors; old-style and new-style
216 numeric formatting; serialization and deserialization of floats and
217 complex numbers using marshal, pickle and json; parsing of float and
218 imaginary literals in Python code; Decimal-to-float conversion.
219
220 The conversions use a Python-adapted version of David Gay's
221 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
222 functions. This code is supported on Windows, and on Unix-like
223 platforms using gcc, icc or suncc as the C compiler. There may be a
224 small number of platforms on which correct operation of this code
225 cannot be guaranteed, so the code is not used: notably, this applies
226 to platforms where the C double format is not IEEE 754 binary64, and
227 to platforms on x86 hardware where the x87 FPU is set to 64-bit
228 precision and Python's configure script is unable to determine how
229 to change the FPU precision. On these platforms conversions use the
230 platform strtod and dtoa, as before.
231
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000232- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000233 now uses the correctly-rounded string <-> float conversions
234 described above (when available), and so produces correctly rounded
235 results that will display nicely under the float repr. There are
236 two related small changes: (1) round now accepts any class with an
237 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000238 floats for the second argument), and (2) an excessively large second
239 integer argument (e.g., round(1.234, 10**100)) no longer raises an
240 exception.
241
Philip Jenveyfab8be22009-11-17 02:42:26 +0000242- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
243
Benjamin Petersone36199b2009-11-12 23:39:44 +0000244- Fix several issues with compile(). The input can now contain Windows and Mac
245 newlines and is no longer required to end in a newline.
246
Mark Dickinsonc04c7c52009-10-26 22:28:14 +0000247- Remove length limitation when constructing a complex number from a
248 unicode string.
249
Raymond Hettingerfa7dadd2009-11-01 20:45:16 +0000250- Issue #7244: itertools.izip_longest() no longer ignores exceptions

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000368- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
369 statement and correctly lookup the __enter__ and __exit__ special methods.
370
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000371- Issue #5829: complex("1e500") no longer raises OverflowError. This
372 makes it consistent with float("1e500") and interpretation of real
373 and imaginary literals.
374

381
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000382- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
383 (1) inf and nan strings with trailing whitespace were incorrectly
384 rejected; (2) parsing of strings representing infinities and nans
385 was locale aware; and (3) the interpretation of fromhex('-nan')
386 didn't match that of float('-nan').
387
Eric Smitha985a3a2009-05-05 18:26:08 +0000388- Issue #5920: For float.__format__, change the behavior with the
389 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
390 to be like 'g' but with at least one decimal point and with a
391 default precision of 12. Previously, the behavior the same but with
392 a default precision of 6. This more closely matches str(), and
393 reduces surprises when adding alignment flags to the empty
394 presentation type. This also affects the new complex.__format__ in
395 the same way.
396
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000397- Issue #5890: in subclasses of 'property' the __doc__ attribute was
398 shadowed by classtype's, even if it was None. property now
399 inserts the __doc__ into the subclass instance __dict__.

425 floats, ints, and longs.
426
427- Issue #5515: 'n' formatting for ints, longs, and floats handles
428 leading zero formatting poorly.
429
430- Issue #5772: For float.__format__, don't add a trailing ".0" if
431 we're using no type code and we have an exponent.
432

437 some builtin types.
438
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000439- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000440 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000441
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000442- Issue #5759: float() didn't call __float__ on str subclasses.

458
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000459- Issue #4688: Add a heuristic so that tuples and dicts containing only
460 untrackable objects are not tracked by the garbage collector. This can
461 reduce the size of collections and therefore the garbage collection overhead
462 on long-running programs, depending on their particular use of datatypes.
463
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000464- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

466 are now between 50% and 150% faster.
467
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000468- Issue #4258: Make it possible to use base 2**30 instead of base
469 2**15 for the internal representation of integers, for performance
470 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
471 --enable-big-digits option to configure, which overrides the
472 default. Add sys.long_info structseq to provide information about
473 the internal format.
474
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000475- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
476 result traceback.__members__ no longer exists.)
477
Mark Dickinson6b265f12009-03-18 16:07:26 +0000478- Issue #4474: PyUnicode_FromWideChar now converts characters outside
479 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4

481
Eric Smith6f42edb2009-03-14 11:57:26 +0000482- Issue #5237: Allow auto-numbered fields in str.format(). For
483 example: '{} {}'.format(1, 2) == '1 2'.
484
Brett Cannon6c4cff02009-03-11 04:51:06 +0000485- Issue #3652: Make the 'line' argument for warnings.showwarning() a
486 requirement. Means the DeprecationWarning from Python 2.6 can go away.
487
Eric Smithe9fb6862009-02-20 14:02:36 +0000488- Issue #5247: Improve error message when unknown format codes are
489 used when using str.format() with str, unicode, long, int, and
490 float arguments.
491
Raymond Hettinger08259e82009-02-18 23:10:19 +0000492- Running Python with the -3 option now also warns about classic division
493 for ints and longs.
494
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000495- Issue #5260: Long integers now consume less memory: average
496 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
497 on a 64-bit system.
498
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000499- Issue #5186: Reduce hash collisions for objects with no __hash__ method by
500 rotating the object pointer by 4 bits to the right.
501
Mark Dickinsonc97c9092009-02-09 14:18:43 +0000502- Issue #4575: Fix Py_IS_INFINITY macro to work correctly on x87 FPUs:
503 it now forces its argument to double before testing for infinity.
504
Benjamin Petersone18ef192009-01-20 14:21:16 +0000505- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
506
Georg Brandl29c6a282009-04-05 20:23:13 +0000507- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000508 were suppressing all exceptions. These include list(), filter(), map(),
509 zip(), and bytearray().
510
Benjamin Peterson596d3062009-01-19 15:42:23 +0000511- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
512 functions.
513

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000530- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
531 collecting the oldest generation) so that allocating lots of objects without
532 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000533 Martin von Löwis at

539 an existing .py counterpart, override the co_filename attributes of all
540 code objects if the original filename is obsolete (which can happen if the
541 file has been renamed, moved, or if it is accessed through different paths).
542 Patch by Ziga Seilnacht and Jean-Paul Calderone.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000623- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW

625 really executed because I cannot move to such directory on win2k)
626
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000627- Issue #4069: When set.remove(element) is used with a set element, the element

651 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
652 step. This avoids problems with counting UTF-8 bytes that ignores the effect
653 of using the replace error handler in PyUnicode_DecodeUTF8().
654
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000655- Issue #3739: The unicode-internal encoder now reports the number of characters

1898 leak-chasing test runs give sensible results. The previous method of
1899 reaping threads could return successfully while some Thread objects were
1900 still referenced. This also introduces a new private function:

1928 test_heapq and test_warnings have been adjusted to use it, tests for
1929 other modules with both C and Python implementations in the stdlib

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002041- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2042
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002043- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2044 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2045 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2046 ``printf`` function, whereas PyString_FromFormat has an independent
2047 implementation and uses "%zd" on all platforms for size_t values.
2048 This makes a difference on win64, where ``printf`` needs "%Id" to display
2049 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002051- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2055 object; previously an int would be returned for small values. the __long__
2056 method is allowed to return either an int or a long, but the behaviour of
2057 float objects should not change to respect backward compatibility.
2058
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002059- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002065 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002066 was correctly parsed but parsing of subsequent arguments failed.
2067
Vinay Sajip35e3b032008-09-01 14:33:59 +00002068- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002069 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2070 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2071 when given a tuple of classes as second argument, were looking up
2072 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2073 type object.
2074

2218-----------------
2219
Guido van Rossumf8402962008-08-20 15:01:50 +00002220- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2221 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2222 extensions do not automatically benefit from the class attribute
2223 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2224 to their tp_flags field if they care. This is a backwards
2225 compatibility feature; in 3.0, all types will use the cache by
2226 default.
2227
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002228- Keyword arguments can now follow starred arguments. (``f(a, *args,
2229 keyword=23)`` is now valid syntax.)
2230
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002231- ctypes function pointers that are COM methods have a boolean True
2232 value again.
2233
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002234- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2235 by denying s# to parse objects that have a releasebuffer procedure,
2236 and introducing s*.
2237
Georg Brandl1e13ea92008-08-11 09:07:59 +00002238- Issue #3537: Fix an assertion failure when an empty but presized dict
2239 object was stored in the freelist.
2240
Mark Dickinsonb6467572008-08-04 21:30:09 +00002241- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2242 ValueError consistently across platforms.
2243
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002244- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2245 (64bit Unix, for example), unichr() would truncate its argument and return
2246 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2247
Neal Norwitze7d8be82008-07-31 17:17:14 +00002248- Apply security patches from Apple.
2249
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002250- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

2252
Antoine Pitrou92f82162008-07-25 22:22:08 +00002253- Issue #1819: function calls with several named parameters are now on
2254 average 35% faster (as measured by pybench).
2255
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002256- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2257 the python debugger steps into a class statement: the free variables (local
2258 variables defined in an outer scope) would be deleted from the outer scope.
2259
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002260- Issue #2620: Overflow checking when allocating or reallocating memory
2261 was not always being done properly in some python types and extension
2262 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2263 all been updated to perform better checks and places in the code that
2264 would previously leak memory on the error path when such an allocation
2265 failed have been fixed.

Benjamin Petersone977ad42008-08-20 01:42:01 +00002272- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2273 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2274
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002275- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2276 version reported by these tools does not necessarily follow the python
2277 version numbering scheme, so the module is less strict when parsing it.
2278
Nick Coghlanf70385a2008-08-18 12:42:46 +00002279- Issue #2235: Added Py3k warnings for types which will become unhashable
2280 under the stricter __hash__ inheritance rules in 3.0. Several types
2281 which did not meet the rules for hash invariants and were already
2282 unhashable in 3.0 have now been explicitly flagged as unhashable in
2283 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2284 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2285
Brett Cannon88f801d2008-08-18 00:46:22 +00002286- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2287 imported into the module but exposed as part of the module's API.
2288
Brett Cannon7b96f072008-08-18 00:41:11 +00002289- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2290
Brett Cannon46225e72008-08-18 00:36:52 +00002291- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

2294
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002295- Issue #3575: Incremental decoder's decode function now takes bytearray
2296 by using 's*' instead of 't#'.
2297
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002298- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002299 fails unicode conversion on 2nd parameter. (windows only)
2300
Facundo Batista94f243a2008-08-17 03:38:39 +00002301- Issue 2464. urllib2 now supports a malformation in the URL received
2302 in a redirect.
2303
Brett Cannonabe423e2008-08-16 21:47:07 +00002304- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002305 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002306
Facundo Batistaeb90b782008-08-16 14:44:07 +00002307- Issue #2776: fixed small issue when handling an URL with double slash
2308 after a 302 response in the case of not going through a proxy.
2309
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002310- Issue #2676: in the email package, content-type parsing was hanging on
2311 pathological input because of quadratic or exponential behaviour of a
2312 regular expression.
2313
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002314- Issue #3476: binary buffered reading through the new "io" library is now
2315 thread-safe.
2316
Brett Cannonbf3157b2008-08-14 05:00:03 +00002317- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2318 since mimetools itself is deprecated. Because modules are cached, all
2319 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2320
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002321- Issue #3134: shutil referenced undefined WindowsError symbol.

Robert Schuppenies14646332008-08-10 11:01:53 +00002323- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2324 menu entries were not deleted.
2325
Brett Cannon83e81842008-08-09 23:30:55 +00002326- Copied the implementation of reduce() to _functools.reduce() to have a
2327 version that did not raise a DeprecationWarning under -3.
2328
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002329- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2330 a MemoryError rather than silently stop the iteration.
2331
Guido van Rossum59ce9012008-08-09 14:55:34 +00002332- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2333 to _sre.compile() will now be rejected. This should not affect anybody
2334 since the re.compile() function never generates invalid re-bytecode.
2335
Skip Montanaroa032bf42008-08-08 22:52:51 +00002336- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2337 upon first access it can be automatically initialized from the csv file if
2338 it wasn't initialized during instantiation.
2339
Brett Cannon3aa2a492008-08-06 22:28:09 +00002340- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2341 the reload() built-in has been removed.
2342
Brett Cannon7e30b672008-08-04 21:52:25 +00002343- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002344 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

2352 raised an AttributeError.
2353
Benjamin Peterson01a24322008-07-28 23:35:27 +00002354- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002355 asking for a specific length. This problem only affected files opened
2356 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002357

2380
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002381- Issue #3394: zipfile.writestr sets external attributes when passed a
2382 file name rather than a ZipInfo instance, so files are extracted with
2383 mode 0600 rather than 000 under Unix.
2384
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002385- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2398 interaction with the tp_hash slot (added in 2.6b2) are now documented
2399
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002400- Issue #643841: The language reference now provides more detailed
2401 coverage of the lookup process for special methods. The disclaimers
2402 regarding lack of coverage of new-style classes have also been
2403 removed, since the coverage is now fairly reasonable.

2407================================
2408
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002409*Release date: 17-Jul-2008*
2410
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002411Core and Builtins
2412-----------------
2413
Georg Brandl3e483f62008-07-16 22:57:41 +00002414- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2415 its methods now allow for items objects that can be converted to
2416 an integer using operator.index().
2417
Mark Dickinson64b7e502008-07-16 09:40:03 +00002418- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2419 produced a ValueError instead of giving the correct float.
2420
Eric Smitha5fa5a22008-07-16 00:11:49 +00002421- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2422 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2423
Mark Dickinson7103aa42008-07-15 19:08:33 +00002424- Issue #3008: the float type has a new instance method 'float.hex'
2425 and a new class method 'float.fromhex' to convert floating-point
2426 numbers to and from hexadecimal strings, respectively.
2427
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002428- Issue #2235: __hash__ is once again inherited by default. To allow
2429 collections.Hashable to remain meaningful in the presence of the
2430 default hash implementation (object.__hash__), it is now possible
2431 to explicit block inheritance of hash by setting __hash__=None at
2432 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2433 level.
2434
Nick Coghlanb028f502008-07-13 14:52:36 +00002435- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2436 the parent module cannot be found while performing an absolute import.
2437 This means that an incorrectly defined __package__ attribute will
2438 now only prevent relative imports in that module rather than causing
2439 all imports from that module to fail.
2440
Nick Coghlan14ff9942008-07-08 14:21:42 +00002441- Issue #2517: Allow unicode messages in Exceptions again by correctly
2442 bypassing the instance dictionary when looking up __unicode__ on
2443 new-style classes.
2444
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002445- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2446 set to a custom object whose write() method happens to install
2447 another file in sys.stdout.
2448
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002449- Issue #3088: Corrected a race condition in classes derived from
2450 threading.local: the first member set by a thread could be saved in
2451 another thread's dictionary.
2452
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002453- Issue #3004: Minor change to slice.indices(): the start and stop
2454 arguments are now treated identically, making the behaviour easier
2455 to describe and understand. For example, slice(None, -10,
2456 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2457 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2458 10, -1).
2459
Georg Brandl278fc502008-07-19 12:46:12 +00002460- Issue #3219: Calling a function with repeated keyword arguments,
2461 f(a=2, a=23), would not cause a syntax error. This was a regression
2462 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002463
Georg Brandl278fc502008-07-19 12:46:12 +00002464- Issue #2862: Make int and float freelist management consistent with
2465 other freelists. Changes their CompactFreeList apis into
2466 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002467

2469-------
2470
Thomas Heller57adf222008-08-14 19:10:48 +00002471- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2472 api functions without holding the GIL, which could lead to a fatal
2473 error when they failed.
2474
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002475- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002483- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2484 ForkingPickler.register() to resolve conflict with ctypes.
2485
Vinay Sajip51e65192008-07-18 09:01:10 +00002486- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002487
Thomas Heller880f5292008-07-15 19:39:38 +00002488- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2489 a valid dlerror() message.
2490
Thomas Heller2bad6572008-07-15 17:19:50 +00002491- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2492 incomplete structure was created.
2493

Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002498- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002499
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002500- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2501 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002502 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002503 content-length. The problem had been corrected in the 2.4 branch, but never
2504 merged into trunk.
2505
Georg Brandle78fbcc2008-07-05 10:13:36 +00002506- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002519- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2520 handling is now the same as that of other special attributes like __name__).
2521
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002522- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
2523 removal in Python 3.0 in favor of urllib2.urlopen().

2911 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002912 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002913
2914 This is controlled by the configure argument ``--with-universal-archs``:
2915
2916 - ``--with-universal-archs=all``: install 4-way universal
2917
2918 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2919
2920 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2921
2922 This option should be used in combination with ``--enable-universalsdk=``.
2923
2924 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002974- Issue #1631171: Re-implement the 'warnings' module in C (the
2975 original Python code has been kept as backup). This will allow for
2976 using the 'warning's machinery in such places as the parser where
2977 use of pure Python code is not possible. Both the ``showarning()``
2978 and ``formatwarning()`` gain an optional 'line' argument which is
2979 not called by default for backwards-compatibility reasons. Setting
2980 ``warnings.showwarning()`` to an implementation that lacks support
2981 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003044- Issue #2550: The approach used by client/server code for obtaining
3045 ports to listen on in network-oriented tests has been refined in an
3046 effort to facilitate running multiple instances of the entire
3047 regression test suite in parallel without issue.
3048 test_support.bind_port() has been fixed such that it will always
3049 return a unique port -- which wasn't always the case with the
3050 previous implementation, especially if socket options had been set
3051 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3052 new implementation of bind_port() will actually raise an exception
3053 if it is passed an AF_INET/SOCK_STREAM socket with either the
3054 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3055 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3056 the socket it's been passed. This currently only applies to
3057 Windows. This option prevents any other sockets from binding to the
3058 host/port we've bound to, thus removing the possibility of the
3059 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3060 when a second SOCK_STREAM socket binds and accepts to a host/port
3061 that's already been bound by another socket. The optional preferred
3062 port parameter to bind_port() has been removed. Under no
3063 circumstances should tests be hard coding ports!
3064
3065 test_support.find_unused_port() has also been introduced, which will
3066 pass a temporary socket object to bind_port() in order to obtain an
3067 unused port. The temporary socket object is then closed and
3068 deleted, and the port is returned. This method should only be used
3069 for obtaining an unused port in order to pass to an external program
3070 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3071 a parameter to a server-oriented class that doesn't give you direct
3072 access to the underlying socket used.
3073
3074 Finally, test_support.HOST has been introduced, which should be used
3075 for the host argument of any relevant socket calls (i.e. bind and
3076 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003077
3078 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003079 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003080 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3081 test_asynchat and test_socket_ssl.
3082
Georg Brandl3ee81df2008-05-17 18:14:43 +00003083 It is now possible for multiple instances of the regression test
3084 suite to run in parallel without issue.

Facundo Batistafc2d0102008-02-23 12:01:13 +00003361 issue 215555 for a discussion.
3362
Eric Smitha73fbe72008-02-23 03:09:44 +00003363- Added the future_builtins module, which contains hex() and oct().
3364 These are the PEP 3127 version of these functions, designed to be
3365 compatible with the hex() and oct() builtins from Python 3.0. They
3366 differ slightly in their output formats from the existing, unchanged
3367 Python 2.6 builtins. The expected usage of the future_builtins
3368 module is:
3369 from future_builtins import hex, oct
3370
Eric Smith7ef40bf2008-02-20 23:34:22 +00003371- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3372 exponents for exponents with absolute value < 100. Follows C99
3373 standard. This is a change on Windows, which would use 3 digits.
3374 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3375 so that any alterations it does to the resulting string will be
3376 available in stringlib/formatter.h (for float.__format__).
3377
Eric Smith5a3c1352008-02-19 13:21:56 +00003378- Implemented PEP 3101, Advanced String Formatting. This adds a new
3379 builtin format(); a format() method for str and unicode; a
3380 __format__() method to object, str, unicode, int, long, float, and
3381 datetime; the class string.Formatter; and the C API
3382 PyObject_Format().
3383
Georg Brandl3ee81df2008-05-17 18:14:43 +00003384- Fixed several potential crashes, all caused by specially crafted
3385 __del__ methods exploiting objects in temporarily inconsistent
3386 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003387
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003388- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003389 prevent a possible crash: an Abstract Base Class would try to access
3390 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003391
Georg Brandl3ee81df2008-05-17 18:14:43 +00003392- Fixed repr() and str() of complex numbers with infinity or nan as
3393 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003394
Georg Brandl3ee81df2008-05-17 18:14:43 +00003395- Clear all free lists during a gc.collect() of the highest generation
3396 in order to allow pymalloc to free more arenas. Python may give back
3397 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003398
Georg Brandl3ee81df2008-05-17 18:14:43 +00003399- Issue #2045: Fix an infinite recursion triggered when printing a
3400 subclass of collections.defaultdict, if its default_factory is set
3401 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003402
Christian Heimesf75dbef2008-02-08 00:11:31 +00003403- Fixed a minor memory leak in dictobject.c. The content of the free
3404 list was not freed on interpreter shutdown.
3405
Georg Brandl3ee81df2008-05-17 18:14:43 +00003406- Limit free list of method and builtin function objects to 256
3407 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003408
Georg Brandl3ee81df2008-05-17 18:14:43 +00003409- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3410 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003411 to compact the internal free lists of pre-allocted ints and floats.
3412
Georg Brandl3ee81df2008-05-17 18:14:43 +00003413- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3414 calls. Python expected the return type int but the fork familie
3415 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003416
Georg Brandl3ee81df2008-05-17 18:14:43 +00003417- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3418 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003419
Georg Brandl3ee81df2008-05-17 18:14:43 +00003420- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3421 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003422
Georg Brandl3ee81df2008-05-17 18:14:43 +00003423- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3424 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003425
Georg Brandl3ee81df2008-05-17 18:14:43 +00003426- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3427 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003428
Georg Brandl3ee81df2008-05-17 18:14:43 +00003429- Patch #1473257: generator objects gain a gi_code attribute. This is
3430 the same object as the func_code attribute of the function that
3431 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003432
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433- Issue #1920: "while 0" statements were completely removed by the
3434 compiler, even in the presence of an "else" clause, which is
3435 supposed to be run when the condition is false. Now the compiler
3436 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003437
Guido van Rossumeead05f2008-01-24 18:21:02 +00003438- A few crashers fixed: weakref_in_del.py (issue #1377858);
3439 loosing_dict_ref.py (issue #1303614, test67.py);
3440 borrowed_ref_[34].py (not in tracker).
3441
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003442- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003443 suppressed while an extension is loaded by calling SetErrorMode in
3444 dynload_win.c. The error is still reported properly.
3445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003447 several extension methods and modules do not work without unicode
3448 support.
3449
Georg Brandl26543b12008-01-21 18:36:51 +00003450- Issue #1882: when compiling code from a string, encoding cookies in the
3451 second line of code were not always recognized correctly.
3452
Georg Brandl14404b62008-01-19 19:27:05 +00003453- Issue #1679: "0x" was taken as a valid integer literal.
3454
Georg Brandl6caad7d2008-01-26 14:19:22 +00003455- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003456 added.
3457
Christian Heimesc94e2b52008-01-14 04:13:37 +00003458- sys.float_info / PyFloat_GetInfo: The floating point information
3459 object was converted from a dict to a specialized structseq object.
3460
Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Patch #1816: Added sys.flags structseq. It exposes the status of
3462 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003463
Georg Brandl3ee81df2008-05-17 18:14:43 +00003464- Objects/structseq.c: Implemented new structseq representation. The
3465 patch makes structseqs (e.g. the return value of os.stat) more
3466 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003467
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468- Patch #1700288: added a type attribute cache that caches method
3469 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003470
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003471- Bug #1776: __import__() no longer accepts filenames on any platform.
3472 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003473
Georg Brandlaed6c662008-01-07 17:25:53 +00003474- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3475
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3477 envvar and sys.dont_write_bytecode attribute. All these can be set
3478 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Improve some exception messages when Windows fails to load an
3481 extension module. Now we get for example '%1 is not a valid Win32
3482 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00003485
Georg Brandl3ee81df2008-05-17 18:14:43 +00003486- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3487 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003488
Christian Heimes0a8143f2007-12-18 23:22:54 +00003489- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003490 and INF. float("nan"), float("inf") and float("-inf") now work on
3491 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003492
Georg Brandl3ee81df2008-05-17 18:14:43 +00003493- Compiler now generates simpler and faster code for dictionary
3494 literals. The oparg for BUILD_MAP now indicates an estimated
3495 dictionary size. There is a new opcode, STORE_MAP, for adding
3496 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003530- Issue #1265: Fix a problem with sys.settrace, if the tracing
3531 function uses a generator expression when at the same time the
3532 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003533
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003534- sets and frozensets now have an isdisjoint() method.
3535
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003536- optimize the performance of builtin.sum().

3539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- The enumerate() builtin function is no longer bounded to sequences
3541 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3542 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003543
Georg Brandl3ee81df2008-05-17 18:14:43 +00003544- Issue #1686386: Tuple's tp_repr did not take into account the
3545 possibility of having a self-referential tuple, which is possible
3546 from C code. Nor did object's tp_str consider that a type's tp_str
3547 could do something that could lead to an inifinite recursion.
3548 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3549 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003550
Georg Brandl3ee81df2008-05-17 18:14:43 +00003551- Issue #1164: It was possible to trigger deadlock when using the
3552 'print' statement to write to a file since the GIL was not released
3553 as needed. Now PyObject_Print() does the right thing along with
3554 various tp_print implementations of the built-in types and those in
3555 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003556
Georg Brandl3ee81df2008-05-17 18:14:43 +00003557- Issue #1147: Exceptions were directly allowing string exceptions in
3558 their throw() method even though string exceptions no longer
3559 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00003564- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003565 PyObject_Call() never calling back out to Python code to trigger
3566 recursion depth updates/checks. Required the creation of a static
3567 RuntimeError instance in case normalizing an exception put the
3568 recursion check value past its limit. Fixes crashers
3569 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003584- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003585 __*__ attributes. (Some already existed, e.g., __doc__ and
3586 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003587
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003588- Add -3 option to the interpreter to warn about features that are
3589 deprecated and will be changed/removed in Python 3.0.
3590
Georg Brandl2134e752007-05-21 20:34:16 +00003591- Patch #1686487: you can now pass any mapping after '**' in function
3592 calls.
3593
Collin Winter62903052007-05-18 23:11:24 +00003594- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003595 "except E as target:". This is to provide forwards compatibility
3596 with Python 3.0.

Vinay Sajip8549ce32007-05-06 17:53:37 +00003603- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003604 setting a plain string, ie don't expand to single letter identifiers.
3605
Raymond Hettinger13936692007-04-11 18:40:58 +00003606- Request #1191699: Slices can now be pickled.
3607
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003608- Request #1193128: str.translate() now allows a None argument for
3609 translations that only remove characters without re-mapping the
3610 remaining characters.
3611
Georg Brandl5cb76c12007-03-21 09:00:39 +00003612- Patch #1682205: a TypeError while unpacking an iterable is no longer
3613 masked by a generic one with the message "unpack non-sequence".

3616
Guido van Rossum143b5642007-03-23 04:58:42 +00003617- Bug #1683368: The object.__init__() and object.__new__() methods are
3618 now stricter in rejecting excess arguments. The only time when
3619 either allows excess arguments is when it is not overridden and the
3620 other one is. For backwards compatibility, when both are
3621 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003622 warning later). Also, type.__init__() insists on the same signature
3623 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003624
Georg Brandl3ee81df2008-05-17 18:14:43 +00003625- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3626 object to complex using its __complex__() method before falling back
3627 to the __float__() method. Therefore, the functions in the cmath
3628 module now can operate on objects that define a __complex__()
3629 method.

3646
Georg Brandl7b9c5552007-03-12 14:30:05 +00003647- Bug #1678647: write a newline after printing an exception in any
3648 case, even when converting the value to a string failed.
3649
Georg Brandl871f1bc2007-03-12 13:17:36 +00003650- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003651 its argument, if it exists. If not, it will work like before. This
3652 allows customizing the output of dir() in the presence of a
3653 __getattr__().

3662 parthensized forms. This means complex(repr(x)) now works instead of
3663 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003664
Georg Brandlaa2321b2007-03-07 00:40:28 +00003665- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003666 makes the filenames the warning module prints much more sensible
3667 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003668

3681 sq_ass_slice instead of the sq_slice slot.
3682
Georg Brandl3ee81df2008-05-17 18:14:43 +00003683- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00003735- Bug #1545497: when given an explicit base, int() did ignore NULs
3736 embedded in the string to convert.
3737
Georg Brandl846f73a2006-10-08 07:11:54 +00003738- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00003786 generator expressions (x for x, in ... ) works again. Fixing this
3787 problem required changing the .pyc magic number. This means that
3788 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004218 AttributeError instead of an IOError when the server's response
4219 didn't contain a valid HTTP status line.

4297 returned string up to the first NUL character.

4310 TestCase and TestSuite subclasses (not instances) are no longer
4311 accepted in TestSuite.addTest(). This should cause no

4313 -- the failure just occurred later, with a more cumbersome
4314 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004591- The implementation of UnicodeError objects has been simplified
4592 (start and end attributes are now stored directly as Py_ssize_t
4593 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00004594
Georg Brandl3ee81df2008-05-17 18:14:43 +00004595- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4596 with RFC 3207 and forgets any knowledge obtained from the server not
4597 obtained from the TLS negotiation itself. Patch contributed by Bill
4598 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004599
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004601 that the SMTP.starttls() caller no longer needs to call ehlo()
4602 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004603 does not claim to support starttls. Adds the
4604 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
4605 Fenner.

4685 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4686 silently miscode subclasses of those types. Now, it raises a
4687 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00004688

Georg Brandl3ee81df2008-05-17 18:14:43 +00004703 time so that opening a database previously created with the DB_DUP
4704 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4705 opens. Specifically: dictionary assignment to a DB object will
4706 replace all values for a given key when the database allows
4707 duplicate values. DB users should use DB.put(k, v) when they want
4708 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004709

4715 characters with ASCII value less than 32. Also, it correctly quotes
4716 dots only if they occur on a single line, as opposed to the previous
4717 behavior of quoting dots if they are the second character of any
4718 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004719

Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Removed the macfs module. It had been deprecated since Python 2.5.
5125 This lead to the deprecation of macostools.touched() as it relied
5126 solely on macfs and was a no-op under OS X.
