12Core and Builtins
13-----------------
14
Ronald Oussoren315cd0c2009-11-19 16:25:21 +000015- Issue #7085: Fix crash when importing some extensions in a thread
16 on MacOSX 10.6.
17
Mark Dickinsonb678de82009-11-19 18:41:49 +000018- Issue #7117: repr(x) for a float x returns a result based on the
19 shortest decimal string that's guaranteed to round back to x under
20 correct rounding (with round-half-to-even rounding mode).
21 Previously it gave a string based on rounding x to 17 decimal digits.
22 repr(x) for a complex number behaves similarly. On platforms where
23 the correctly-rounded strtod and dtoa code is not supported (see below),
24 repr is unchanged.
25
26- Issue #7117: On almost all platforms: float-to-string and
27 string-to-float conversions within Python are now correctly rounded.
28 Places these conversions occur include: str for floats and complex
29 numbers; the float and complex constructors; old-style and new-style
30 numeric formatting; serialization and deserialization of floats and
31 complex numbers using marshal, pickle and json; parsing of float and
32 imaginary literals in Python code; Decimal-to-float conversion.
33
34 The conversions use a Python-adapted version of David Gay's
35 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
36 functions. This code is supported on Windows, and on Unix-like
37 platforms using gcc, icc or suncc as the C compiler. There may be a
38 small number of platforms on which correct operation of this code
39 cannot be guaranteed, so the code is not used: notably, this applies
40 to platforms where the C double format is not IEEE 754 binary64, and
41 to platforms on x86 hardware where the x87 FPU is set to 64-bit
42 precision and Python's configure script is unable to determine how
43 to change the FPU precision. On these platforms conversions use the
44 platform strtod and dtoa, as before.
45
Mark Dickinsonbd15a062009-11-18 19:33:35 +000046- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +000047 now uses the correctly-rounded string <-> float conversions
48 described above (when available), and so produces correctly rounded
49 results that will display nicely under the float repr. There are
50 two related small changes: (1) round now accepts any class with an
51 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +000052 floats for the second argument), and (2) an excessively large second
53 integer argument (e.g., round(1.234, 10**100)) no longer raises an
54 exception.
55
Philip Jenveyfab8be22009-11-17 02:42:26 +000056- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.
57
Benjamin Petersone36199b2009-11-12 23:39:44 +000058- Fix several issues with compile(). The input can now contain Windows and Mac

71 interpreter is killed. Patch by Adam Olsen.
72
Eric Smithc12781a2009-10-19 14:38:14 +000073- Issue #7168: Document PyFloat_AsString and PyFloat_AsReprString, and

Benjamin Peterson1880d8b2009-05-25 13:13:44 +0000182- Issue #6101: A new opcode, SETUP_WITH, has been added to speed up the with
183 statement and correctly lookup the __enter__ and __exit__ special methods.
184
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000185- Issue #5829: complex("1e500") no longer raises OverflowError. This
186 makes it consistent with float("1e500") and interpretation of real
187 and imaginary literals.
188
Hirokazu Yamamotoa4f90182009-05-17 02:58:36 +0000189- Issue #3527: Removed Py_WIN_WIDE_FILENAMES which is not used any more.

195
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000196- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
197 (1) inf and nan strings with trailing whitespace were incorrectly
198 rejected; (2) parsing of strings representing infinities and nans
199 was locale aware; and (3) the interpretation of fromhex('-nan')
200 didn't match that of float('-nan').
201
Eric Smitha985a3a2009-05-05 18:26:08 +0000202- Issue #5920: For float.__format__, change the behavior with the
203 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
204 to be like 'g' but with at least one decimal point and with a
205 default precision of 12. Previously, the behavior the same but with
206 a default precision of 6. This more closely matches str(), and
207 reduces surprises when adding alignment flags to the empty
208 presentation type. This also affects the new complex.__format__ in
209 the same way.
210
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000211- Issue #5890: in subclasses of 'property' the __doc__ attribute was
212 shadowed by classtype's, even if it was None. property now
213 inserts the __doc__ into the subclass instance __dict__.
214
Antoine Pitrou653dece2009-05-04 18:32:32 +0000215- Issue #4426: The UTF-7 decoder was too strict and didn't accept some legal

Eric Smith9139cc62009-04-30 00:58:58 +0000219 format(complex(1, 2./3), '.5') now produces a sensible result.
220
Mark Dickinson92fcc9c2009-04-29 20:41:00 +0000221- Issue #5864: Fix empty format code formatting for floats so that it
222 never gives more than the requested number of significant digits.
223
Eric Smithcac7af62009-04-27 19:04:37 +0000224- Issue #5793: Rationalize isdigit / isalpha / tolower, etc. Includes
225 new Py_ISDIGIT / Py_ISALPHA / Py_TOLOWER, etc. in pctypes.h.
226
Martin v. Löwis99f27792009-04-26 00:53:18 +0000227- Issue #4971: Fix titlecase for characters that are their own
228 titlecase, but not their own uppercase.
229
Eric Smith068f0652009-04-25 21:40:15 +0000230- Issue #5835: Deprecate PyOS_ascii_formatd and replace it with
231 _PyOS_double_to_string or PyOS_double_to_string.
232
Benjamin Peterson5083dc52009-04-25 00:41:22 +0000233- Issue #5283: Setting __class__ in __del__ caused a segfault.
234
Mark Dickinson95bc9802009-04-24 12:46:53 +0000235- Issue #5816: complex(repr(z)) now recovers z exactly, even when
236 z involves nans, infs or negative zeros.
237
Eric Smithaca19e62009-04-22 13:29:05 +0000238- Implement PEP 378, Format Specifier for Thousands Separator, for
239 floats, ints, and longs.
240
241- Issue #5515: 'n' formatting for ints, longs, and floats handles
242 leading zero formatting poorly.
243
244- Issue #5772: For float.__format__, don't add a trailing ".0" if
245 we're using no type code and we have an exponent.
246
Mark Dickinson6736cf82009-04-20 21:13:33 +0000247- Issue #3166: Make long -> float (and int -> float) conversions
248 correctly rounded.
249
Benjamin Petersond4d400c2009-04-18 20:12:47 +0000250- Issue #5787: object.__getattribute__(some_type, "__bases__") segfaulted on
251 some builtin types.
252
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000253- Issue #1869: fix a couple of minor round() issues. round(5e15+1)
Eric Smith9139cc62009-04-30 00:58:58 +0000254 was giving 5e15+2; round(-0.0) was losing the sign of the zero.
Mark Dickinson1bdf7e92009-04-18 14:59:42 +0000255
Benjamin Peterson99d36f12009-04-15 21:26:36 +0000256- Issue #5759: float() didn't call __float__ on str subclasses.
257
Georg Brandl3c4a5462009-04-12 12:08:12 +0000258- Issue #5704: the "-3" command-line option now implies "-t".
259

271 the end sys.path, for compatibility with the system install of Python.
272
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000273- Issue #4688: Add a heuristic so that tuples and dicts containing only
274 untrackable objects are not tracked by the garbage collector. This can
275 reduce the size of collections and therefore the garbage collection overhead
276 on long-running programs, depending on their particular use of datatypes.
277
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000278- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to
279 improve its performance. Long divisions and remainder operations
280 are now between 50% and 150% faster.
281
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000282- Issue #4258: Make it possible to use base 2**30 instead of base
283 2**15 for the internal representation of integers, for performance
284 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
285 --enable-big-digits option to configure, which overrides the
286 default. Add sys.long_info structseq to provide information about
287 the internal format.
288
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000289- Issue #4034: Fix weird attribute error messages of the traceback object. (As a
290 result traceback.__members__ no longer exists.)
291
Mark Dickinson6b265f12009-03-18 16:07:26 +0000292- Issue #4474: PyUnicode_FromWideChar now converts characters outside
293 the BMP to surrogate pairs, on systems with sizeof(wchar_t) == 4
294 and sizeof(Py_UNICODE) == 2.
295
Eric Smith6f42edb2009-03-14 11:57:26 +0000296- Issue #5237: Allow auto-numbered fields in str.format(). For
297 example: '{} {}'.format(1, 2) == '1 2'.
298
Brett Cannon6c4cff02009-03-11 04:51:06 +0000299- Issue #3652: Make the 'line' argument for warnings.showwarning() a
300 requirement. Means the DeprecationWarning from Python 2.6 can go away.
301
Eric Smithe9fb6862009-02-20 14:02:36 +0000302- Issue #5247: Improve error message when unknown format codes are

304 float arguments.
305
Raymond Hettinger08259e82009-02-18 23:10:19 +0000306- Running Python with the -3 option now also warns about classic division
307 for ints and longs.

Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000309- Issue #5260: Long integers now consume less memory: average
310 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
311 on a 64-bit system.
312
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000313- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

320
Georg Brandl29c6a282009-04-05 20:23:13 +0000321- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000322 were suppressing all exceptions. These include list(), filter(), map(),
323 zip(), and bytearray().
324
Benjamin Peterson596d3062009-01-19 15:42:23 +0000325- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
326 functions.

332
Antoine Pitrouc2f02212009-01-13 23:13:52 +0000333- Issue #4935: The overflow checking code in the expandtabs() method common
334 to str, bytes and bytearray could be optimized away by the compiler, letting
335 the interpreter segfault instead of raising an error.
336
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000337- Issue #3720: Fix a crash when an iterator modifies its class and removes its

343
Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000344- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
345 collecting the oldest generation) so that allocating lots of objects without
346 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000347 Martin von Löwis at

351
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000352- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
353 an existing .py counterpart, override the co_filename attributes of all
354 code objects if the original filename is obsolete (which can happen if the
355 file has been renamed, moved, or if it is accessed through different paths).
356 Patch by Ziga Seilnacht and Jean-Paul Calderone.
357
Martin v. Löwis5344c992009-01-02 20:32:55 +0000358- Issue #4075: Use OutputDebugStringW in Py_FatalError.

Hirokazu Yamamoto99a1b202009-01-01 15:45:39 +0000360- Issue #4797: IOError.filename was not set when _fileio.FileIO failed to open
361 file with `str' filename on Windows.
362
Antoine Pitrouaa687902009-01-01 14:11:22 +0000363- Issue #3680: Reference cycles created through a dict, set or deque iterator
364 did not get collected.
365
Nick Coghlan180e4002008-12-30 01:18:48 +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
Benjamin Peterson7af65562008-12-29 17:56:58 +0000369- Issue #4764: With io.open, IOError.filename is set when trying to open a
370 directory on POSIX systems.
371
Benjamin Petersonfe231b02008-12-29 17:47:42 +0000372- Issue #4764: IOError.filename is set when trying to open a directory on POSIX

376 bytearray.translate(). It was always allowed for bytes.translate().
377
Skip Montanarof205c132008-12-23 03:30:15 +0000378- Added test case to ensure attempts to read from a file opened for writing
379 fail.
380
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000381- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

391 context manager returns a value that cannot be converted to a bool.
392
Jeffrey Yasskinffd42cf2008-12-10 07:35:02 +0000393- Issue #4597: Fixed several opcodes that weren't always propagating
394 exceptions.
395
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000396- Issue #4445: Replace "sizeof(PyStringObject)" with
397 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
398 str instances. On a typical machine this saves 3 bytes of memory
399 (on average) per string allocation.
400
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000401- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
402 interpreter to abort ("Fatal Python error: Could not reset the stack!")
403 instead of throwing a MemoryError.
404
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000405- Issue #3689: The list reversed iterator now supports __length_hint__
406 instead of __len__. Behavior now matches other reversed iterators.
407
Benjamin Petersonc078f922008-11-21 22:27:24 +0000408- Issue #4367: Python would segfault during compiling when the unicodedata
409 module couldn't be imported and \N escapes were present.
410
Vinay Sajip213faca2008-12-03 23:22:58 +0000411- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000412 method on file objects with closefd=False. The file descriptor is still
413 kept open but the file object behaves like a closed file. The ``FileIO``
414 object also got a new readonly attribute ``closefd``.
415
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000416- Issue #4348: Some bytearray methods returned that didn't cause any change to
417 the bytearray, returned the same bytearray instead of a copy.
418
Amaury Forgeot d'Arc7cfe7ea2008-11-18 22:19:37 +0000419- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
420
Benjamin Peterson273c2332008-11-17 22:39:09 +0000421- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
422
Benjamin Peterson6624a9f2008-11-03 15:14:51 +0000423- Issue #4048: The parser module now correctly validates relative imports.
424
Benjamin Petersondcee09d2008-10-31 02:16:05 +0000425- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
426 exec statement.
427
Amaury Forgeot d'Arc69a9c5b2008-10-30 21:18:34 +0000428- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
429 method does not return iterators for the 4th and 5th items.
430
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000431- Issue #4209: Enabling unicode_literals and the print_function in the same
432 __future__ import didn't work.
433
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000434- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000435 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000436
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000437- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
438 returned a path longer than MAX_PATH. (But It's doubtful this code path is
439 really executed because I cannot move to such directory on win2k)
440
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000441- Issue #4069: When set.remove(element) is used with a set element, the element
442 is temporarily replaced with an equivalent frozenset. But the eventual
443 KeyError would always report the empty frozenset([]) as the missing key. Now
444 it correctly refers to the initial element.
445
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000446- Issue #4509: Various issues surrounding resize of bytearray objects to
447 which there are buffer exports.

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000461- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
462 returned them on 64bit platforms.
463
Walter Dörwalded960ac2009-05-03 22:36:33 +0000464- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
465 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
466 step. This avoids problems with counting UTF-8 bytes that ignores the effect
467 of using the replace error handler in PyUnicode_DecodeUTF8().
468
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000469- Issue #3739: The unicode-internal encoder now reports the number of characters
470 consumed like any other encoder (instead of the number of bytes).

Nick Coghlan49868cb2009-11-15 07:30:34 +0000495- Issue #6816: runpy now provides a run_path function that allows Python code
496 to execute file paths that refer to source or compiled Python files as well
497 as zipfiles, directories and other valid sys.path entries that contain a
498 __main__.py file. This allows applications that run other Python scripts to
499 support the same flexibility as the CPython command line itself.

1654 leak-chasing test runs give sensible results. The previous method of

1798
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001799- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1800 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1801 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1802 ``printf`` function, whereas PyString_FromFormat has an independent
1803 implementation and uses "%zd" on all platforms for size_t values.
1804 This makes a difference on win64, where ``printf`` needs "%Id" to display
1805 64bit values.

1811 object; previously an int would be returned for small values. the __long__

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001822 was correctly parsed but parsing of subsequent arguments failed.

Vinay Sajip35e3b032008-09-01 14:33:59 +00001824- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001825 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1826 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1827 when given a tuple of classes as second argument, were looking up
1828 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1829 type object.

1974-----------------
1975
Guido van Rossumf8402962008-08-20 15:01:50 +00001976- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1977 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1978 extensions do not automatically benefit from the class attribute
1979 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1980 to their tp_flags field if they care. This is a backwards
1981 compatibility feature; in 3.0, all types will use the cache by
1982 default.
1983
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001984- Keyword arguments can now follow starred arguments. (``f(a, *args,

Georg Brandl1e13ea92008-08-11 09:07:59 +00001994- Issue #3537: Fix an assertion failure when an empty but presized dict
1995 object was stored in the freelist.
1996
Mark Dickinsonb6467572008-08-04 21:30:09 +00001997- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1998 ValueError consistently across platforms.
1999
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002000- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2001 (64bit Unix, for example), unichr() would truncate its argument and return
2002 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2003
Neal Norwitze7d8be82008-07-31 17:17:14 +00002004- Apply security patches from Apple.
2005
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002006- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2007 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2008
Antoine Pitrou92f82162008-07-25 22:22:08 +00002009- Issue #1819: function calls with several named parameters are now on
2010 average 35% faster (as measured by pybench).
2011
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002012- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2013 the python debugger steps into a class statement: the free variables (local
2014 variables defined in an outer scope) would be deleted from the outer scope.
2015
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002016- Issue #2620: Overflow checking when allocating or reallocating memory
2017 was not always being done properly in some python types and extension
2018 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2019 all been updated to perform better checks and places in the code that
2020 would previously leak memory on the error path when such an allocation
2021 failed have been fixed.

2027
Benjamin Petersone977ad42008-08-20 01:42:01 +00002028- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2029 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2030
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002031- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2032 version reported by these tools does not necessarily follow the python
2033 version numbering scheme, so the module is less strict when parsing it.
2034
Nick Coghlanf70385a2008-08-18 12:42:46 +00002035- Issue #2235: Added Py3k warnings for types which will become unhashable
2036 under the stricter __hash__ inheritance rules in 3.0. Several types
2037 which did not meet the rules for hash invariants and were already
2038 unhashable in 3.0 have now been explicitly flagged as unhashable in
2039 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2040 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2041
Brett Cannon88f801d2008-08-18 00:46:22 +00002042- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2043 imported into the module but exposed as part of the module's API.
2044

2065
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002066- Issue #2676: in the email package, content-type parsing was hanging on

Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002070- Issue #3476: binary buffered reading through the new "io" library is now
2071 thread-safe.
2072
Brett Cannonbf3157b2008-08-14 05:00:03 +00002073- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2074 since mimetools itself is deprecated. Because modules are cached, all
2075 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2076
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002077- Issue #3134: shutil referenced undefined WindowsError symbol.

2087
Guido van Rossum59ce9012008-08-09 14:55:34 +00002088- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2089 to _sre.compile() will now be rejected. This should not affect anybody
2090 since the re.compile() function never generates invalid re-bytecode.

2094 it wasn't initialized during instantiation.
2095
Brett Cannon3aa2a492008-08-06 22:28:09 +00002096- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2097 the reload() built-in has been removed.
2098
Brett Cannon7e30b672008-08-04 21:52:25 +00002099- Changed code in the following modules/packages to remove warnings raised

2108 raised an AttributeError.
2109
Benjamin Peterson01a24322008-07-28 23:35:27 +00002110- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002111 asking for a specific length. This problem only affected files opened
2112 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002113

2136
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002137- Issue #3394: zipfile.writestr sets external attributes when passed a
2138 file name rather than a ZipInfo instance, so files are extracted with
2139 mode 0600 rather than 000 under Unix.
2140
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002141- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2142 argument in python 2.5, this broke code that subclassed Popen to include its
2143 own poll method. Fixed my moving _deadstate to an _internal_poll method.

Nick Coghlan6e8fef02008-08-18 13:14:22 +00002153- Issue #2235: the C API function PyObject_HashNotImplemented and its
2154 interaction with the tp_hash slot (added in 2.6b2) are now documented
2155
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002156- Issue #643841: The language reference now provides more detailed
2157 coverage of the lookup process for special methods. The disclaimers
2158 regarding lack of coverage of new-style classes have also been
2159 removed, since the coverage is now fairly reasonable.

2163================================
2164
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002165*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002167Core and Builtins
2168-----------------
2169
Georg Brandl3e483f62008-07-16 22:57:41 +00002170- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2171 its methods now allow for items objects that can be converted to
2172 an integer using operator.index().
2173
Mark Dickinson64b7e502008-07-16 09:40:03 +00002174- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2175 produced a ValueError instead of giving the correct float.
2176
Eric Smitha5fa5a22008-07-16 00:11:49 +00002177- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2178 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2179
Mark Dickinson7103aa42008-07-15 19:08:33 +00002180- Issue #3008: the float type has a new instance method 'float.hex'
2181 and a new class method 'float.fromhex' to convert floating-point
2182 numbers to and from hexadecimal strings, respectively.
2183
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002184- Issue #2235: __hash__ is once again inherited by default. To allow
2185 collections.Hashable to remain meaningful in the presence of the
2186 default hash implementation (object.__hash__), it is now possible
2187 to explicit block inheritance of hash by setting __hash__=None at
2188 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2189 level.
2190
Nick Coghlanb028f502008-07-13 14:52:36 +00002191- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2192 the parent module cannot be found while performing an absolute import.
2193 This means that an incorrectly defined __package__ attribute will
2194 now only prevent relative imports in that module rather than causing
2195 all imports from that module to fail.
2196
Nick Coghlan14ff9942008-07-08 14:21:42 +00002197- Issue #2517: Allow unicode messages in Exceptions again by correctly
2198 bypassing the instance dictionary when looking up __unicode__ on
2199 new-style classes.
2200
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002201- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2202 set to a custom object whose write() method happens to install
2203 another file in sys.stdout.
2204
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002205- Issue #3088: Corrected a race condition in classes derived from
2206 threading.local: the first member set by a thread could be saved in
2207 another thread's dictionary.
2208
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002209- Issue #3004: Minor change to slice.indices(): the start and stop
2210 arguments are now treated identically, making the behaviour easier
2211 to describe and understand. For example, slice(None, -10,
2212 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2213 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2214 10, -1).
2215
Georg Brandl278fc502008-07-19 12:46:12 +00002216- Issue #3219: Calling a function with repeated keyword arguments,
2217 f(a=2, a=23), would not cause a syntax error. This was a regression
2218 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002219
Georg Brandl278fc502008-07-19 12:46:12 +00002220- Issue #2862: Make int and float freelist management consistent with
2221 other freelists. Changes their CompactFreeList apis into
2222 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002223

2225-------
2226
Thomas Heller57adf222008-08-14 19:10:48 +00002227- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2228 api functions without holding the GIL, which could lead to a fatal
2229 error when they failed.
2230
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002231- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2240 ForkingPickler.register() to resolve conflict with ctypes.
2241
Vinay Sajip51e65192008-07-18 09:01:10 +00002242- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

Thomas Heller880f5292008-07-15 19:39:38 +00002244- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2245 a valid dlerror() message.
2246
Thomas Heller2bad6572008-07-15 17:19:50 +00002247- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2248 incomplete structure was created.
2249
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002250- Issue #3339: dummy_thread.acquire() should not return None.

2253
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002254- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002255
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002256- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2257 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002258 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002259 content-length. The problem had been corrected in the 2.4 branch, but never
2260 merged into trunk.
2261
Georg Brandle78fbcc2008-07-05 10:13:36 +00002262- Issue #2663: add filtering capability to shutil.copytree().

2267
2268- Issue #1746: Correct handling of zipfile archive comments (previously
2269 archives with comments over 4k were flagged as invalid). Allow writing
Vinay Sajip51e65192008-07-18 09:01:10 +00002270 Zip files with archives by setting the 'comment' attribute of a ZipFile.
Martin v. Löwis8c436412008-07-03 12:51:14 +00002271
Vinay Sajip51e65192008-07-18 09:01:10 +00002272- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002273 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +00002274
Nick Coghlanc060b0e2008-07-02 13:09:19 +00002275- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl5cc774e2008-06-11 20:28:06 +00002668 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002669
2670 This is controlled by the configure argument ``--with-universal-archs``:
2671
2672 - ``--with-universal-archs=all``: install 4-way universal
2673
2674 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2675
2676 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2677
2678 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002730- Issue #1631171: Re-implement the 'warnings' module in C (the
2731 original Python code has been kept as backup). This will allow for
2732 using the 'warning's machinery in such places as the parser where
2733 use of pure Python code is not possible. Both the ``showarning()``
2734 and ``formatwarning()`` gain an optional 'line' argument which is
2735 not called by default for backwards-compatibility reasons. Setting
2736 ``warnings.showwarning()`` to an implementation that lacks support
2737 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002800- Issue #2550: The approach used by client/server code for obtaining
2801 ports to listen on in network-oriented tests has been refined in an
2802 effort to facilitate running multiple instances of the entire
2803 regression test suite in parallel without issue.
2804 test_support.bind_port() has been fixed such that it will always
2805 return a unique port -- which wasn't always the case with the
2806 previous implementation, especially if socket options had been set
2807 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2808 new implementation of bind_port() will actually raise an exception
2809 if it is passed an AF_INET/SOCK_STREAM socket with either the
2810 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2811 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2812 the socket it's been passed. This currently only applies to
2813 Windows. This option prevents any other sockets from binding to the
2814 host/port we've bound to, thus removing the possibility of the
2815 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2816 when a second SOCK_STREAM socket binds and accepts to a host/port
2817 that's already been bound by another socket. The optional preferred
2818 port parameter to bind_port() has been removed. Under no
2819 circumstances should tests be hard coding ports!
2820
2821 test_support.find_unused_port() has also been introduced, which will
2822 pass a temporary socket object to bind_port() in order to obtain an
2823 unused port. The temporary socket object is then closed and
2824 deleted, and the port is returned. This method should only be used
2825 for obtaining an unused port in order to pass to an external program
2826 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2827 a parameter to a server-oriented class that doesn't give you direct
2828 access to the underlying socket used.
2829
2830 Finally, test_support.HOST has been introduced, which should be used
2831 for the host argument of any relevant socket calls (i.e. bind and
2832 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002833
2834 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002836 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2837 test_asynchat and test_socket_ssl.
2838
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839 It is now possible for multiple instances of the regression test
2840 suite to run in parallel without issue.

3106Core and builtins
3107-----------------
3108
Fred Drakea8ee94b2008-03-01 02:45:07 +00003109- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003110 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003111
Georg Brandlad61bc82008-02-23 15:11:18 +00003112- Issue #2067: file.__exit__() now calls subclasses' close() method.
3113
3114- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003115
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003116- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003117 issue 215555 for a discussion.
3118
Eric Smitha73fbe72008-02-23 03:09:44 +00003119- Added the future_builtins module, which contains hex() and oct().
3120 These are the PEP 3127 version of these functions, designed to be
3121 compatible with the hex() and oct() builtins from Python 3.0. They
3122 differ slightly in their output formats from the existing, unchanged
3123 Python 2.6 builtins. The expected usage of the future_builtins
3124 module is:
3125 from future_builtins import hex, oct
3126
Eric Smith7ef40bf2008-02-20 23:34:22 +00003127- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3128 exponents for exponents with absolute value < 100. Follows C99
3129 standard. This is a change on Windows, which would use 3 digits.
3130 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3131 so that any alterations it does to the resulting string will be
3132 available in stringlib/formatter.h (for float.__format__).
3133
Eric Smith5a3c1352008-02-19 13:21:56 +00003134- Implemented PEP 3101, Advanced String Formatting. This adds a new
3135 builtin format(); a format() method for str and unicode; a
3136 __format__() method to object, str, unicode, int, long, float, and
3137 datetime; the class string.Formatter; and the C API
3138 PyObject_Format().
3139
Georg Brandl3ee81df2008-05-17 18:14:43 +00003140- Fixed several potential crashes, all caused by specially crafted
3141 __del__ methods exploiting objects in temporarily inconsistent
3142 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003143
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003144- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003145 prevent a possible crash: an Abstract Base Class would try to access
3146 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003147
Georg Brandl3ee81df2008-05-17 18:14:43 +00003148- Fixed repr() and str() of complex numbers with infinity or nan as
3149 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003150
Georg Brandl3ee81df2008-05-17 18:14:43 +00003151- Clear all free lists during a gc.collect() of the highest generation
3152 in order to allow pymalloc to free more arenas. Python may give back
3153 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003154
Georg Brandl3ee81df2008-05-17 18:14:43 +00003155- Issue #2045: Fix an infinite recursion triggered when printing a
3156 subclass of collections.defaultdict, if its default_factory is set
3157 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003158
Christian Heimesf75dbef2008-02-08 00:11:31 +00003159- Fixed a minor memory leak in dictobject.c. The content of the free
3160 list was not freed on interpreter shutdown.
3161
Georg Brandl3ee81df2008-05-17 18:14:43 +00003162- Limit free list of method and builtin function objects to 256
3163 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003164
Georg Brandl3ee81df2008-05-17 18:14:43 +00003165- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3166 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003167 to compact the internal free lists of pre-allocted ints and floats.
3168
Georg Brandl3ee81df2008-05-17 18:14:43 +00003169- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3170 calls. Python expected the return type int but the fork familie
3171 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003172
Georg Brandl3ee81df2008-05-17 18:14:43 +00003173- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3174 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003175
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3177 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003178
Georg Brandl3ee81df2008-05-17 18:14:43 +00003179- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3180 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3183 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003184
Georg Brandl3ee81df2008-05-17 18:14:43 +00003185- Patch #1473257: generator objects gain a gi_code attribute. This is
3186 the same object as the func_code attribute of the function that
3187 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003188
Georg Brandl3ee81df2008-05-17 18:14:43 +00003189- Issue #1920: "while 0" statements were completely removed by the
3190 compiler, even in the presence of an "else" clause, which is
3191 supposed to be run when the condition is false. Now the compiler
3192 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003193
Guido van Rossumeead05f2008-01-24 18:21:02 +00003194- A few crashers fixed: weakref_in_del.py (issue #1377858);
3195 loosing_dict_ref.py (issue #1303614, test67.py);
3196 borrowed_ref_[34].py (not in tracker).
3197
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003198- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003199 suppressed while an extension is loaded by calling SetErrorMode in
3200 dynload_win.c. The error is still reported properly.
3201
Georg Brandl3ee81df2008-05-17 18:14:43 +00003202- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003203 several extension methods and modules do not work without unicode
3204 support.
3205
Georg Brandl26543b12008-01-21 18:36:51 +00003206- Issue #1882: when compiling code from a string, encoding cookies in the
3207 second line of code were not always recognized correctly.
3208
Georg Brandl14404b62008-01-19 19:27:05 +00003209- Issue #1679: "0x" was taken as a valid integer literal.
3210
Georg Brandl6caad7d2008-01-26 14:19:22 +00003211- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003212 added.
3213
Christian Heimesc94e2b52008-01-14 04:13:37 +00003214- sys.float_info / PyFloat_GetInfo: The floating point information
3215 object was converted from a dict to a specialized structseq object.
3216
Georg Brandl3ee81df2008-05-17 18:14:43 +00003217- Patch #1816: Added sys.flags structseq. It exposes the status of
3218 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003219
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- Objects/structseq.c: Implemented new structseq representation. The
3221 patch makes structseqs (e.g. the return value of os.stat) more
3222 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Patch #1700288: added a type attribute cache that caches method
3225 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003226
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003227- Bug #1776: __import__() no longer accepts filenames on any platform.
3228 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003229
Georg Brandlaed6c662008-01-07 17:25:53 +00003230- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3231
Georg Brandl3ee81df2008-05-17 18:14:43 +00003232- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3233 envvar and sys.dont_write_bytecode attribute. All these can be set
3234 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003235
Georg Brandl3ee81df2008-05-17 18:14:43 +00003236- Improve some exception messages when Windows fails to load an
3237 extension module. Now we get for example '%1 is not a valid Win32
3238 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003239
Georg Brandl3ee81df2008-05-17 18:14:43 +00003240- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003242- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3243 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003244
Christian Heimes0a8143f2007-12-18 23:22:54 +00003245- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003246 and INF. float("nan"), float("inf") and float("-inf") now work on
3247 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003248
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Compiler now generates simpler and faster code for dictionary
3250 literals. The oparg for BUILD_MAP now indicates an estimated
3251 dictionary size. There is a new opcode, STORE_MAP, for adding
3252 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003253
Georg Brandl3ee81df2008-05-17 18:14:43 +00003254- Issue #1638: %zd configure test fails on Linux.

3267 __package__ attribute.
3268
Georg Brandl3ee81df2008-05-17 18:14:43 +00003269- Issue #1402: Fix a crash on exit, when another thread is still
3270 running, and if the deallocation of its frames somehow calls the
3271 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003272

3282 file can now be directly executed by passing their name to the
3283 interpreter. The directory/zipfile is automatically inserted as the
3284 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003285
Georg Brandl3ee81df2008-05-17 18:14:43 +00003286- Issue #1265: Fix a problem with sys.settrace, if the tracing
3287 function uses a generator expression when at the same time the
3288 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003289
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003290- sets and frozensets now have an isdisjoint() method.
3291
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003292- optimize the performance of builtin.sum().
3293
Neal Norwitz44f326e2007-10-05 05:29:17 +00003294- Fix warnings found by the new version of the Coverity checker.
3295
Georg Brandl3ee81df2008-05-17 18:14:43 +00003296- The enumerate() builtin function is no longer bounded to sequences
3297 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3298 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003299
Georg Brandl3ee81df2008-05-17 18:14:43 +00003300- Issue #1686386: Tuple's tp_repr did not take into account the
3301 possibility of having a self-referential tuple, which is possible
3302 from C code. Nor did object's tp_str consider that a type's tp_str
3303 could do something that could lead to an inifinite recursion.
3304 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3305 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003306
Georg Brandl3ee81df2008-05-17 18:14:43 +00003307- Issue #1164: It was possible to trigger deadlock when using the
3308 'print' statement to write to a file since the GIL was not released
3309 as needed. Now PyObject_Print() does the right thing along with
3310 various tp_print implementations of the built-in types and those in
3311 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003313- Issue #1147: Exceptions were directly allowing string exceptions in
3314 their throw() method even though string exceptions no longer
3315 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003316
Georg Brandl3ee81df2008-05-17 18:14:43 +00003317- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannon1e534b52007-09-07 04:18:30 +00003320- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003321 PyObject_Call() never calling back out to Python code to trigger
3322 recursion depth updates/checks. Required the creation of a static
3323 RuntimeError instance in case normalizing an exception put the
3324 recursion check value past its limit. Fixes crashers
3325 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003340- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003341 __*__ attributes. (Some already existed, e.g., __doc__ and
3342 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003343
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003344- Add -3 option to the interpreter to warn about features that are
3345 deprecated and will be changed/removed in Python 3.0.
3346

3348 calls.
3349
Collin Winter62903052007-05-18 23:11:24 +00003350- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003351 "except E as target:". This is to provide forwards compatibility
3352 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003353
Brett Cannon229cee22007-05-05 01:34:02 +00003354- Deprecate BaseException.message as per PEP 352.
3355
Georg Brandl3ee81df2008-05-17 18:14:43 +00003356- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003357 inherited from a builtin base.
3358
Vinay Sajip8549ce32007-05-06 17:53:37 +00003359- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003360 setting a plain string, ie don't expand to single letter identifiers.
3361
Raymond Hettinger13936692007-04-11 18:40:58 +00003362- Request #1191699: Slices can now be pickled.
3363
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003364- Request #1193128: str.translate() now allows a None argument for
3365 translations that only remove characters without re-mapping the
3366 remaining characters.
3367
Georg Brandl5cb76c12007-03-21 09:00:39 +00003368- Patch #1682205: a TypeError while unpacking an iterable is no longer
3369 masked by a generic one with the message "unpack non-sequence".
3370
Neal Norwitzaa754b72007-03-21 06:39:48 +00003371- Remove unused file Python/fmod.c.
3372
Guido van Rossum143b5642007-03-23 04:58:42 +00003373- Bug #1683368: The object.__init__() and object.__new__() methods are
3374 now stricter in rejecting excess arguments. The only time when
3375 either allows excess arguments is when it is not overridden and the
3376 other one is. For backwards compatibility, when both are
3377 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003378 warning later). Also, type.__init__() insists on the same signature
3379 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003380
Georg Brandl3ee81df2008-05-17 18:14:43 +00003381- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3382 object to complex using its __complex__() method before falling back
3383 to the __float__() method. Therefore, the functions in the cmath
3384 module now can operate on objects that define a __complex__()
3385 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003386
Georg Brandl3ee81df2008-05-17 18:14:43 +00003387- Patch #1623563: allow __class__ assignment for classes with
3388 __slots__. The old and the new class are still required to have the
3389 same slot names.

3402
Georg Brandl7b9c5552007-03-12 14:30:05 +00003403- Bug #1678647: write a newline after printing an exception in any
3404 case, even when converting the value to a string failed.
3405
Georg Brandl871f1bc2007-03-12 13:17:36 +00003406- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407 its argument, if it exists. If not, it will work like before. This
3408 allows customizing the output of dir() in the presence of a
3409 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003410
Collin Winter276887b2007-03-12 16:11:39 +00003411- Patch #922167: Python no longer segfaults when faced with infinitely
3412 self-recursive reload() calls (as reported by bug #742342).
3413
Georg Brandl3ee81df2008-05-17 18:14:43 +00003414- Patch #1675981: remove unreachable code from ``type.__new__()``

3418 parthensized forms. This means complex(repr(x)) now works instead of
3419 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003420
Georg Brandlaa2321b2007-03-07 00:40:28 +00003421- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003422 makes the filenames the warning module prints much more sensible
3423 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003424
Georg Brandl49aafc92007-03-07 00:34:46 +00003425- Variant of patch #697613: don't exit the interpreter on a SystemExit
3426 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003427 variable is given, but break into the interactive interpreter just
3428 like on other exceptions or normal program exit.

3434 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003435
Georg Brandl0fca97a2007-03-05 22:28:08 +00003436- Patch #1674228: when assigning a slice (old-style), check for the
3437 sq_ass_slice instead of the sq_slice slot.
3438
Georg Brandl3ee81df2008-05-17 18:14:43 +00003439- When printing an unraisable error, don't print exceptions. before
3440 the name. This duplicates the behavior whening normally printing
3441 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00003442
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00003449- Bug #1377858: Fix the segfaulting of the interpreter when an object
3450 created a weakref on itself during a __del__ call for new-style
3451 classes (classic classes still have the bug).

Georg Brandl3ee81df2008-05-17 18:14:43 +00003974 AttributeError instead of an IOError when the server's response
3975 didn't contain a valid HTTP status line.

3982 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003983 correctly now.
3984

Georg Brandl92a6bae2007-03-13 17:43:32 +00004008- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004009 are set for invalid interpolation sequences that would lead to
4010 errors on reading back those values.

4064
Georg Brandl3ee81df2008-05-17 18:14:43 +00004065- unittest now verifies more of its assumptions. In particular,
4066 TestCase and TestSuite subclasses (not instances) are no longer
4067 accepted in TestSuite.addTest(). This should cause no
4068 incompatibility since it never made sense with ordinary subclasses

Georg Brandl3ee81df2008-05-17 18:14:43 +00004351- Issue #829951: In the smtplib module, SMTP.starttls() now complies
4352 with RFC 3207 and forgets any knowledge obtained from the server not
4353 obtained from the TLS negotiation itself. Patch contributed by Bill
4354 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004355
Georg Brandl3ee81df2008-05-17 18:14:43 +00004356- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004357 that the SMTP.starttls() caller no longer needs to call ehlo()
4358 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004359 does not claim to support starttls. Adds the
4360 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4441 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4442 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004459 time so that opening a database previously created with the DB_DUP
4460 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4461 opens. Specifically: dictionary assignment to a DB object will
4462 replace all values for a given key when the database allows
4463 duplicate values. DB users should use DB.put(k, v) when they want
4464 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004465

4471 characters with ASCII value less than 32. Also, it correctly quotes
4472 dots only if they occur on a single line, as opposed to the previous
4473 behavior of quoting dots if they are the second character of any
4474 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004810- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
4811 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
4812 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004813
4814- Patch #1720595: add T_BOOL to the range of structmember types.
4815

4818
Georg Brandl3ee81df2008-05-17 18:14:43 +00004819- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4820 of w# format code incorrectly truncated the length to an int, even
4821 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4822 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004823
Georg Brandl3ee81df2008-05-17 18:14:43 +00004824- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
4825 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004827- PEP 3123: Provide forward compatibility with Python 3.0, while
4828 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
4829 and PyVarObject_HEAD_INIT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004831- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
4832 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004833
4834- Patch #1733960: Allow T_LONGLONG to accept ints.
4835
4836- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
4837
Christian Heimes000a0742008-01-03 22:16:32 +00004838- Added a new API function ``PyImport_ImportModuleNoBlock``.

4841
4842- Fix some leftovers from the conversion from int to Py_ssize_t
4843 (relevant to strings and sequences of more than 2**31 items).
4844
4845- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4846 outside of pystate.c and should not be necessary.
4847
Georg Brandl3ee81df2008-05-17 18:14:43 +00004848- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4849 absolute imports. In earlier versions they might have used relative
4850 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004851
Georg Brandl3ee81df2008-05-17 18:14:43 +00004852- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4853 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004854
Georg Brandl3ee81df2008-05-17 18:14:43 +00004855- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004862- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
4863 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4864 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4865 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004866
Georg Brandl3ee81df2008-05-17 18:14:43 +00004867- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00004880- Removed the macfs module. It had been deprecated since Python 2.5.
4881 This lead to the deprecation of macostools.touched() as it relied
4882 solely on macfs and was a no-op under OS X.
