Benjamin Petersonecdae192010-01-04 00:43:01 +000071- The __complex__ method is now looked up on the class of instances to make it
72 consistent with other special methods.
73
Antoine Pitrou5b7139a2010-01-02 21:12:58 +000074- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
75 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
76
Mark Dickinson1b34d252010-01-01 17:27:30 +000077- Issue #5080: A number of functions and methods previously produced a
78 DeprecationWarning when passed a float argument where an integer was
79 expected. These functions and methods now raise TypeError instead.
80 The majority of the effects of this change are in the extension
81 modules, but some core functions and methods are affected: notably
82 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
83 methods.
84
Benjamin Peterson0f02d392009-12-30 19:34:10 +000085- Issue #7604: Deleting an unset slotted attribute did not raise an

Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +000094- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
95 used to drop the time part of the result.
96
Mark Dickinson46572832009-12-27 14:55:57 +000097- Issue #1811: improve accuracy and cross-platform consistency for
98 true division of integers: the result of a/b is now correctly
99 rounded for ints a and b (at least on IEEE 754 platforms), and in
100 particular does not depend on the internal representation of a long.
101
Ezio Melottif84caf42009-12-24 22:25:17 +0000102- Issue #6108: unicode(exception) and str(exception) should return the same
103 message when only __str__ (and not __unicode__) is overridden in the subclass.
104
Ronald Oussoren92919a62009-12-24 13:30:58 +0000105- Issue #6834: replace the implementation for the 'python' and 'pythonw'
106 executables on OSX.
107
108 These executables now work properly with the arch(1) command:
109 ``arch -ppc python`` will start a universal binary version of python
110 in PPC mode (unlike previous releases).
111
R. David Murray0a0a1a82009-12-14 16:28:26 +0000112- Issue #1680159: unicode coercion during an 'in' operation no longer masks

126 by Arfrever.
127
Antoine Pitrou80157252010-01-08 19:20:17 +0000128- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
129 renaming of `cPickle` to `pickle`. The warning was annoying since there's
130 no alternative to cPickle if you care about performance. Patch by Florent
131 Xicluna.

141 speedups by wrapping it in an `io.BufferedReader`. Patch by Nir Aides.
142
143- Issue #3972: httplib.HTTPConnection now accepts an optional source_address

163
Benjamin Petersonddd392c2009-12-13 19:19:07 +0000164- Issue #7349: Make methods of file objects in the io module accept None as an
165 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
166 the same as passing no argument.
167
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000168- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument
169 like other file objects.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000239- Issue #7419: setlocale() could crash the interpreter on Windows when called
240 with invalid values.
241
Eric Smithc4ab8332009-11-29 17:40:57 +0000242- Issue #3382: 'F' formatting for float and complex now convert the
243 result to upper case. This only affects 'inf' and 'nan', since 'f'
244 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000245
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000246- Remove switch from "%f" formatting to "%g" formatting for floats
247 larger than 1e50 in absolute value.
248
Mark Dickinson18cfada2009-11-23 18:46:41 +0000249- Remove restrictions on precision when formatting floats. E.g.,
250 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
251 requested 120 significant digits instead.
252
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000253- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000257- Issue #7085: Fix crash when importing some extensions in a thread
258 on MacOSX 10.6.
259
Mark Dickinsonb678de82009-11-19 18:41:49 +0000260- Issue #7117: repr(x) for a float x returns a result based on the
261 shortest decimal string that's guaranteed to round back to x under
262 correct rounding (with round-half-to-even rounding mode).
263 Previously it gave a string based on rounding x to 17 decimal digits.
264 repr(x) for a complex number behaves similarly. On platforms where
265 the correctly-rounded strtod and dtoa code is not supported (see below),
266 repr is unchanged.
267
268- Issue #7117: On almost all platforms: float-to-string and
269 string-to-float conversions within Python are now correctly rounded.
270 Places these conversions occur include: str for floats and complex
271 numbers; the float and complex constructors; old-style and new-style
272 numeric formatting; serialization and deserialization of floats and
273 complex numbers using marshal, pickle and json; parsing of float and
274 imaginary literals in Python code; Decimal-to-float conversion.
275
276 The conversions use a Python-adapted version of David Gay's
277 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
278 functions. This code is supported on Windows, and on Unix-like
279 platforms using gcc, icc or suncc as the C compiler. There may be a
280 small number of platforms on which correct operation of this code
281 cannot be guaranteed, so the code is not used: notably, this applies
282 to platforms where the C double format is not IEEE 754 binary64, and
283 to platforms on x86 hardware where the x87 FPU is set to 64-bit
284 precision and Python's configure script is unable to determine how
285 to change the FPU precision. On these platforms conversions use the
286 platform strtod and dtoa, as before.
287
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000288- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000289 now uses the correctly-rounded string <-> float conversions
290 described above (when available), and so produces correctly rounded
291 results that will display nicely under the float repr. There are
292 two related small changes: (1) round now accepts any class with an
293 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000294 floats for the second argument), and (2) an excessively large second
295 integer argument (e.g., round(1.234, 10**100)) no longer raises an
296 exception.
297
Philip Jenveyfab8be22009-11-17 02:42:26 +0000298- Issue #1757126: Fix the cyrillic-asian alias for the ptcp154 encoding.

426
Mark Dickinsona4e0efa2009-05-20 18:43:07 +0000427- Issue #5829: complex("1e500") no longer raises OverflowError. This

437
Mark Dickinsonb1d45852009-05-11 15:33:08 +0000438- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
439 (1) inf and nan strings with trailing whitespace were incorrectly
440 rejected; (2) parsing of strings representing infinities and nans
441 was locale aware; and (3) the interpretation of fromhex('-nan')
442 didn't match that of float('-nan').
443
Eric Smitha985a3a2009-05-05 18:26:08 +0000444- Issue #5920: For float.__format__, change the behavior with the
445 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
446 to be like 'g' but with at least one decimal point and with a
447 default precision of 12. Previously, the behavior the same but with
448 a default precision of 6. This more closely matches str(), and
449 reduces surprises when adding alignment flags to the empty
450 presentation type. This also affects the new complex.__format__ in
451 the same way.
452
R. David Murray7ba8e1c2009-05-04 22:16:24 +0000453- Issue #5890: in subclasses of 'property' the __doc__ attribute was

516 untrackable objects are not tracked by the garbage collector. This can
517 reduce the size of collections and therefore the garbage collection overhead
518 on long-running programs, depending on their particular use of datatypes.
519
Mark Dickinson0b666bf2009-03-23 18:25:13 +0000520- Issue #5512: Rewrite PyLong long division algorithm (x_divrem) to

553 on a 64-bit system.
554
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000555- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

562
Georg Brandl29c6a282009-04-05 20:23:13 +0000563- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000564 were suppressing all exceptions. These include list(), filter(), map(),

604
Antoine Pitrouaa687902009-01-01 14:11:22 +0000605- Issue #3680: Reference cycles created through a dict, set or deque iterator

636 exceptions.
637
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000638- Issue #4445: Replace "sizeof(PyStringObject)" with
639 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
640 str instances. On a typical machine this saves 3 bytes of memory
641 (on average) per string allocation.
642
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000643- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
644 interpreter to abort ("Fatal Python error: Could not reset the stack!")
645 instead of throwing a MemoryError.
646
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000647- Issue #3689: The list reversed iterator now supports __length_hint__
648 instead of __len__. Behavior now matches other reversed iterators.
649
Benjamin Petersonc078f922008-11-21 22:27:24 +0000650- Issue #4367: Python would segfault during compiling when the unicodedata

652
Vinay Sajip213faca2008-12-03 23:22:58 +0000653- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000654 method on file objects with closefd=False. The file descriptor is still
655 kept open but the file object behaves like a closed file. The ``FileIO``
656 object also got a new readonly attribute ``closefd``.
657
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000658- Issue #4348: Some bytearray methods returned that didn't cause any change to
659 the bytearray, returned the same bytearray instead of a copy.
660

671 method does not return iterators for the 4th and 5th items.
672
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000673- Issue #4209: Enabling unicode_literals and the print_function in the same
674 __future__ import didn't work.
675
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000676- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000677 because it is a reserved word in 3.x.
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000678
Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000679- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
680 returned a path longer than MAX_PATH. (But It's doubtful this code path is
681 really executed because I cannot move to such directory on win2k)
682
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000683- Issue #4069: When set.remove(element) is used with a set element, the element
684 is temporarily replaced with an equivalent frozenset. But the eventual
685 KeyError would always report the empty frozenset([]) as the missing key. Now
686 it correctly refers to the initial element.
687
Antoine Pitrouae5bece2008-12-06 21:29:24 +0000688- Issue #4509: Various issues surrounding resize of bytearray objects to

Gregory P. Smith2b3eb372009-04-05 23:48:26 +0000703- Issue #5705: os.setuid() would not accept values > 2**31-1 but pwd.getpwnam()
704 returned them on 64bit platforms.
705
Walter Dörwalded960ac2009-05-03 22:36:33 +0000706- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
707 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
708 step. This avoids problems with counting UTF-8 bytes that ignores the effect
709 of using the replace error handler in PyUnicode_DecodeUTF8().
710
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000711- Issue #3739: The unicode-internal encoder now reports the number of characters
712 consumed like any other encoder (instead of the number of bytes).
713
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000714- Issue #2422: When compiled with the ``--with-valgrind`` option, the
715 pymalloc allocator will be automatically disabled when running under
716 Valgrind. This gives improved memory leak detection when running
717 under Valgrind, while taking advantage of pymalloc at other times.

Nick Coghlan49868cb2009-11-15 07:30:34 +0000786- Issue #6816: runpy now provides a run_path function that allows Python code
787 to execute file paths that refer to source or compiled Python files as well
788 as zipfiles, directories and other valid sys.path entries that contain a

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002097- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2098
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002099- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2100 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2101 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2102 ``printf`` function, whereas PyString_FromFormat has an independent
2103 implementation and uses "%zd" on all platforms for size_t values.
2104 This makes a difference on win64, where ``printf`` needs "%Id" to display
2105 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00002107- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

2111 object; previously an int would be returned for small values. the __long__

Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002115- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +00002121 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002122 was correctly parsed but parsing of subsequent arguments failed.
2123
Vinay Sajip35e3b032008-09-01 14:33:59 +00002124- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002125 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2126 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2127 when given a tuple of classes as second argument, were looking up
2128 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2129 type object.
2130
Neal Norwitz18aa3882008-08-24 05:04:52 +00002131- Fix crashes on memory allocation failure found with failmalloc.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002268What's New in Python 2.6 beta 3?
2269================================
2270
Barry Warsaw07a4a382008-08-21 01:15:08 +00002271*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002272
2273Core and Builtins
2274-----------------
2275
Guido van Rossumf8402962008-08-20 15:01:50 +00002276- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2277 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2278 extensions do not automatically benefit from the class attribute
2279 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2280 to their tp_flags field if they care. This is a backwards
2281 compatibility feature; in 3.0, all types will use the cache by
2282 default.
2283
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002284- Keyword arguments can now follow starred arguments. (``f(a, *args,
2285 keyword=23)`` is now valid syntax.)
2286
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002287- ctypes function pointers that are COM methods have a boolean True
2288 value again.
2289
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002290- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2291 by denying s# to parse objects that have a releasebuffer procedure,
2292 and introducing s*.
2293
Georg Brandl1e13ea92008-08-11 09:07:59 +00002294- Issue #3537: Fix an assertion failure when an empty but presized dict
2295 object was stored in the freelist.
2296
Mark Dickinsonb6467572008-08-04 21:30:09 +00002297- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2298 ValueError consistently across platforms.
2299
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002300- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2301 (64bit Unix, for example), unichr() would truncate its argument and return
2302 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2303
Neal Norwitze7d8be82008-07-31 17:17:14 +00002304- Apply security patches from Apple.
2305
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002306- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2307 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2308
Antoine Pitrou92f82162008-07-25 22:22:08 +00002309- Issue #1819: function calls with several named parameters are now on
2310 average 35% faster (as measured by pybench).
2311
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002312- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2313 the python debugger steps into a class statement: the free variables (local
2314 variables defined in an outer scope) would be deleted from the outer scope.
2315
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002316- Issue #2620: Overflow checking when allocating or reallocating memory
2317 was not always being done properly in some python types and extension
2318 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2319 all been updated to perform better checks and places in the code that
2320 would previously leak memory on the error path when such an allocation
2321 failed have been fixed.
2322
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002323Library
2324-------
2325
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002326- Issue #3612: Added some missing basic types in ctypes.wintypes.
2327
Benjamin Petersone977ad42008-08-20 01:42:01 +00002328- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2329 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2330
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002331- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2332 version reported by these tools does not necessarily follow the python
2333 version numbering scheme, so the module is less strict when parsing it.
2334
Nick Coghlanf70385a2008-08-18 12:42:46 +00002335- Issue #2235: Added Py3k warnings for types which will become unhashable
2336 under the stricter __hash__ inheritance rules in 3.0. Several types
2337 which did not meet the rules for hash invariants and were already
2338 unhashable in 3.0 have now been explicitly flagged as unhashable in
2339 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2340 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2341
Brett Cannon88f801d2008-08-18 00:46:22 +00002342- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2343 imported into the module but exposed as part of the module's API.
2344
Brett Cannon7b96f072008-08-18 00:41:11 +00002345- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2346
Brett Cannon46225e72008-08-18 00:36:52 +00002347- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
2348
Brett Cannon25c9d6a2008-08-17 22:10:11 +00002349- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2350
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002351- Issue #3575: Incremental decoder's decode function now takes bytearray
2352 by using 's*' instead of 't#'.
2353
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002354- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002355 fails unicode conversion on 2nd parameter. (windows only)
2356
Facundo Batista94f243a2008-08-17 03:38:39 +00002357- Issue 2464. urllib2 now supports a malformation in the URL received
2358 in a redirect.
2359
Brett Cannonabe423e2008-08-16 21:47:07 +00002360- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002361 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002362
Facundo Batistaeb90b782008-08-16 14:44:07 +00002363- Issue #2776: fixed small issue when handling an URL with double slash
2364 after a 302 response in the case of not going through a proxy.
2365
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002366- Issue #2676: in the email package, content-type parsing was hanging on
2367 pathological input because of quadratic or exponential behaviour of a
2368 regular expression.
2369
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002370- Issue #3476: binary buffered reading through the new "io" library is now
2371 thread-safe.
2372
Brett Cannonbf3157b2008-08-14 05:00:03 +00002373- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2374 since mimetools itself is deprecated. Because modules are cached, all
2375 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2376
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002377- Issue #3134: shutil referenced undefined WindowsError symbol.
2378
Robert Schuppenies14646332008-08-10 11:01:53 +00002379- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2380 menu entries were not deleted.
2381
Brett Cannon83e81842008-08-09 23:30:55 +00002382- Copied the implementation of reduce() to _functools.reduce() to have a
2383 version that did not raise a DeprecationWarning under -3.
2384
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002385- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2386 a MemoryError rather than silently stop the iteration.
2387
Guido van Rossum59ce9012008-08-09 14:55:34 +00002388- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2389 to _sre.compile() will now be rejected. This should not affect anybody
2390 since the re.compile() function never generates invalid re-bytecode.
2391
Skip Montanaroa032bf42008-08-08 22:52:51 +00002392- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2393 upon first access it can be automatically initialized from the csv file if
2394 it wasn't initialized during instantiation.
2395
Brett Cannon3aa2a492008-08-06 22:28:09 +00002396- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2397 the reload() built-in has been removed.
2398
Brett Cannon7e30b672008-08-04 21:52:25 +00002399- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002400 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00002401 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
2402 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
2403 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
2404 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
2405 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00002406
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00002407- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
2408 raised an AttributeError.
2409
Benjamin Peterson01a24322008-07-28 23:35:27 +00002410- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002411 asking for a specific length. This problem only affected files opened
2412 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00002413
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00002414- Issue #3449: Update decimal module to use most recent specification
2415 (v. 1.68) and tests (v. 2.58) from IBM.
2416
Skip Montanarof9ac43f2008-07-27 00:50:41 +00002417- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
2418
Raymond Hettinger8c664e82008-07-25 18:43:33 +00002419- Issue 1592: Improve error reporting when operations are attempted
2420 on a closed shelf.

2423
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002424- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
2425
2426- Issue #3303: Fix a crash in locale.strcoll() when calling it with
2427 invalid arguments.
2428
2429- Issue #3302: Fix several crashes when calling locale's gettext functions
2430 with None arguments.
2431
2432- Issue #3389: Allow resolving dotted names for handlers in logging
2433 configuration files.
2434
2435- Deprecate the sunaudio module for removal in Python 3.0.
2436
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00002437- Issue #3394: zipfile.writestr sets external attributes when passed a
2438 file name rather than a ZipInfo instance, so files are extracted with
2439 mode 0600 rather than 000 under Unix.
2440
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002441- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
2442 argument in python 2.5, this broke code that subclassed Popen to include its
2443 own poll method. Fixed my moving _deadstate to an _internal_poll method.
2444

2451-------------
2452
Nick Coghlan6e8fef02008-08-18 13:14:22 +00002453- Issue #2235: the C API function PyObject_HashNotImplemented and its
2454 interaction with the tp_hash slot (added in 2.6b2) are now documented
2455
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00002456- Issue #643841: The language reference now provides more detailed
2457 coverage of the lookup process for special methods. The disclaimers
2458 regarding lack of coverage of new-style classes have also been
2459 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002462What's New in Python 2.6 beta 2?
2463================================
2464
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002465*Release date: 17-Jul-2008*
2466
Raymond Hettingere3ae6552008-06-20 04:18:15 +00002467Core and Builtins
2468-----------------
2469
Georg Brandl3e483f62008-07-16 22:57:41 +00002470- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2471 its methods now allow for items objects that can be converted to
2472 an integer using operator.index().
2473
Mark Dickinson64b7e502008-07-16 09:40:03 +00002474- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2475 produced a ValueError instead of giving the correct float.
2476
Eric Smitha5fa5a22008-07-16 00:11:49 +00002477- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2478 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2479
Mark Dickinson7103aa42008-07-15 19:08:33 +00002480- Issue #3008: the float type has a new instance method 'float.hex'
2481 and a new class method 'float.fromhex' to convert floating-point
2482 numbers to and from hexadecimal strings, respectively.
2483
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002484- Issue #2235: __hash__ is once again inherited by default. To allow
2485 collections.Hashable to remain meaningful in the presence of the
2486 default hash implementation (object.__hash__), it is now possible
2487 to explicit block inheritance of hash by setting __hash__=None at
2488 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2489 level.
2490
Nick Coghlanb028f502008-07-13 14:52:36 +00002491- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2492 the parent module cannot be found while performing an absolute import.
2493 This means that an incorrectly defined __package__ attribute will
2494 now only prevent relative imports in that module rather than causing
2495 all imports from that module to fail.
2496
Nick Coghlan14ff9942008-07-08 14:21:42 +00002497- Issue #2517: Allow unicode messages in Exceptions again by correctly
2498 bypassing the instance dictionary when looking up __unicode__ on
2499 new-style classes.
2500
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002501- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2502 set to a custom object whose write() method happens to install
2503 another file in sys.stdout.
2504
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002505- Issue #3088: Corrected a race condition in classes derived from
2506 threading.local: the first member set by a thread could be saved in
2507 another thread's dictionary.
2508
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002509- Issue #3004: Minor change to slice.indices(): the start and stop
2510 arguments are now treated identically, making the behaviour easier
2511 to describe and understand. For example, slice(None, -10,
2512 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2513 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2514 10, -1).
2515
Georg Brandl278fc502008-07-19 12:46:12 +00002516- Issue #3219: Calling a function with repeated keyword arguments,
2517 f(a=2, a=23), would not cause a syntax error. This was a regression
2518 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002519
Georg Brandl278fc502008-07-19 12:46:12 +00002520- Issue #2862: Make int and float freelist management consistent with
2521 other freelists. Changes their CompactFreeList apis into
2522 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +00002523

2525-------
2526
Thomas Heller57adf222008-08-14 19:10:48 +00002527- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2528 api functions without holding the GIL, which could lead to a fatal
2529 error when they failed.
2530
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002531- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Jesse Noller13e9d582008-07-16 14:32:36 +00002539- Issue #3125: Remove copy_reg in multiprocessing and replace it with
2540 ForkingPickler.register() to resolve conflict with ctypes.
2541
Vinay Sajip51e65192008-07-18 09:01:10 +00002542- Issue #3090: Fixed ARCHFLAGS parsing on OS/X

2545 a valid dlerror() message.
2546
Thomas Heller2bad6572008-07-15 17:19:50 +00002547- Issue #3258: Fixed a crash when a ctypes POINTER type to an
2548 incomplete structure was created.
2549
Brett Cannon3d0b9f02008-07-13 01:15:07 +00002550- Issue #3339: dummy_thread.acquire() should not return None.
2551
Raymond Hettingerb01713e2008-07-10 14:34:57 +00002552- Issue #3285: Fractions from_float() and from_decimal() accept Integral arguments.
2553

2967 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002968 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002969
2970 This is controlled by the configure argument ``--with-universal-archs``:
2971
2972 - ``--with-universal-archs=all``: install 4-way universal
2973
2974 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2975
2976 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2977
2978 This option should be used in combination with ``--enable-universalsdk=``.
2979
2980 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

3017 two handlers that derive the same default base class.
Amaury Forgeot d'Arc96865852008-04-22 21:14:41 +00003018
Christian Heimese74c8f22008-04-19 02:23:57 +00003019- Added kill, terminate and send_signal(sig) to subprocess.Popen.
3020
Georg Brandl3ee81df2008-05-17 18:14:43 +00003021- Added phase(z) -> phi, polar(z) -> r, phi and rect(r, phi) -> z to
3022 the cmath module.
Christian Heimes6f341092008-04-18 23:13:07 +00003023

Georg Brandl3ee81df2008-05-17 18:14:43 +00003030- Issue #1631171: Re-implement the 'warnings' module in C (the
3031 original Python code has been kept as backup). This will allow for
3032 using the 'warning's machinery in such places as the parser where
3033 use of pure Python code is not possible. Both the ``showarning()``
3034 and ``formatwarning()`` gain an optional 'line' argument which is
3035 not called by default for backwards-compatibility reasons. Setting
3036 ``warnings.showwarning()`` to an implementation that lacks support
3037 for the ``line`` argument will raise a DeprecationWarning.

3061
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003062- The getpass module has been improved on Unix. It now uses /dev/tty
3063 by default and uses stderr instead of stdout. A GetPassWarning is
3064 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00003065

Georg Brandl3ee81df2008-05-17 18:14:43 +00003079- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003080 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003100- Issue #2550: The approach used by client/server code for obtaining
3101 ports to listen on in network-oriented tests has been refined in an
3102 effort to facilitate running multiple instances of the entire
3103 regression test suite in parallel without issue.
3104 test_support.bind_port() has been fixed such that it will always
3105 return a unique port -- which wasn't always the case with the
3106 previous implementation, especially if socket options had been set
3107 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3108 new implementation of bind_port() will actually raise an exception
3109 if it is passed an AF_INET/SOCK_STREAM socket with either the
3110 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3111 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3112 the socket it's been passed. This currently only applies to
3113 Windows. This option prevents any other sockets from binding to the
3114 host/port we've bound to, thus removing the possibility of the
3115 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3116 when a second SOCK_STREAM socket binds and accepts to a host/port
3117 that's already been bound by another socket. The optional preferred
3118 port parameter to bind_port() has been removed. Under no
3119 circumstances should tests be hard coding ports!
3120
3121 test_support.find_unused_port() has also been introduced, which will
3122 pass a temporary socket object to bind_port() in order to obtain an
3123 unused port. The temporary socket object is then closed and
3124 deleted, and the port is returned. This method should only be used
3125 for obtaining an unused port in order to pass to an external program
3126 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3127 a parameter to a server-oriented class that doesn't give you direct
3128 access to the underlying socket used.
3129
3130 Finally, test_support.HOST has been introduced, which should be used
3131 for the host argument of any relevant socket calls (i.e. bind and
3132 connect).

3406Core and builtins
3407-----------------
3408
Fred Drakea8ee94b2008-03-01 02:45:07 +00003409- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003410 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00003411
Georg Brandlad61bc82008-02-23 15:11:18 +00003412- Issue #2067: file.__exit__() now calls subclasses' close() method.
3413
3414- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003415
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003416- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003417 issue 215555 for a discussion.
3418
Eric Smitha73fbe72008-02-23 03:09:44 +00003419- Added the future_builtins module, which contains hex() and oct().
3420 These are the PEP 3127 version of these functions, designed to be
3421 compatible with the hex() and oct() builtins from Python 3.0. They
3422 differ slightly in their output formats from the existing, unchanged
3423 Python 2.6 builtins. The expected usage of the future_builtins
3424 module is:
3425 from future_builtins import hex, oct
3426
Eric Smith7ef40bf2008-02-20 23:34:22 +00003427- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3428 exponents for exponents with absolute value < 100. Follows C99
3429 standard. This is a change on Windows, which would use 3 digits.
3430 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3431 so that any alterations it does to the resulting string will be
3432 available in stringlib/formatter.h (for float.__format__).
3433
Eric Smith5a3c1352008-02-19 13:21:56 +00003434- Implemented PEP 3101, Advanced String Formatting. This adds a new
3435 builtin format(); a format() method for str and unicode; a
3436 __format__() method to object, str, unicode, int, long, float, and
3437 datetime; the class string.Formatter; and the C API
3438 PyObject_Format().
3439
Georg Brandl3ee81df2008-05-17 18:14:43 +00003440- Fixed several potential crashes, all caused by specially crafted
3441 __del__ methods exploiting objects in temporarily inconsistent
3442 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003443
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003444- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003445 prevent a possible crash: an Abstract Base Class would try to access
3446 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00003447
Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Fixed repr() and str() of complex numbers with infinity or nan as
3449 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00003450
Georg Brandl3ee81df2008-05-17 18:14:43 +00003451- Clear all free lists during a gc.collect() of the highest generation
3452 in order to allow pymalloc to free more arenas. Python may give back
3453 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003454
Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Issue #2045: Fix an infinite recursion triggered when printing a
3456 subclass of collections.defaultdict, if its default_factory is set
3457 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003458
Christian Heimesf75dbef2008-02-08 00:11:31 +00003459- Fixed a minor memory leak in dictobject.c. The content of the free
3460 list was not freed on interpreter shutdown.
3461
Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Limit free list of method and builtin function objects to 256
3463 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00003464
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3466 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003467 to compact the internal free lists of pre-allocted ints and floats.
3468
Georg Brandl3ee81df2008-05-17 18:14:43 +00003469- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3470 calls. Python expected the return type int but the fork familie
3471 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003472
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473- Issue #1678380: Fix a bug that identifies 0j and -0j when they
3474 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00003475
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476- Issue #2025: Add tuple.count() and tuple.index() methods to comply
3477 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00003478
Georg Brandl3ee81df2008-05-17 18:14:43 +00003479- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
3480 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00003481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
3483 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00003484
Georg Brandl3ee81df2008-05-17 18:14:43 +00003485- Patch #1473257: generator objects gain a gi_code attribute. This is
3486 the same object as the func_code attribute of the function that
3487 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003488
Georg Brandl3ee81df2008-05-17 18:14:43 +00003489- Issue #1920: "while 0" statements were completely removed by the
3490 compiler, even in the presence of an "else" clause, which is
3491 supposed to be run when the condition is false. Now the compiler
3492 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003493
Guido van Rossumeead05f2008-01-24 18:21:02 +00003494- A few crashers fixed: weakref_in_del.py (issue #1377858);
3495 loosing_dict_ref.py (issue #1303614, test67.py);
3496 borrowed_ref_[34].py (not in tracker).
3497
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003498- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003499 suppressed while an extension is loaded by calling SetErrorMode in
3500 dynload_win.c. The error is still reported properly.
3501
Georg Brandl3ee81df2008-05-17 18:14:43 +00003502- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003503 several extension methods and modules do not work without unicode
3504 support.
3505
Georg Brandl26543b12008-01-21 18:36:51 +00003506- Issue #1882: when compiling code from a string, encoding cookies in the
3507 second line of code were not always recognized correctly.
3508
Georg Brandl14404b62008-01-19 19:27:05 +00003509- Issue #1679: "0x" was taken as a valid integer literal.
3510
Georg Brandl6caad7d2008-01-26 14:19:22 +00003511- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003512 added.
3513
Christian Heimesc94e2b52008-01-14 04:13:37 +00003514- sys.float_info / PyFloat_GetInfo: The floating point information
3515 object was converted from a dict to a specialized structseq object.
3516
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517- Patch #1816: Added sys.flags structseq. It exposes the status of
3518 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003519
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520- Objects/structseq.c: Implemented new structseq representation. The
3521 patch makes structseqs (e.g. the return value of os.stat) more
3522 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003523
Georg Brandl3ee81df2008-05-17 18:14:43 +00003524- Patch #1700288: added a type attribute cache that caches method
3525 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003526
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003527- Bug #1776: __import__() no longer accepts filenames on any platform.
3528 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003529

3531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3533 envvar and sys.dont_write_bytecode attribute. All these can be set
3534 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003535
Georg Brandl3ee81df2008-05-17 18:14:43 +00003536- Improve some exception messages when Windows fails to load an
3537 extension module. Now we get for example '%1 is not a valid Win32
3538 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003542- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3543 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003544
Christian Heimes0a8143f2007-12-18 23:22:54 +00003545- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003546 and INF. float("nan"), float("inf") and float("-inf") now work on
3547 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003548
Georg Brandl3ee81df2008-05-17 18:14:43 +00003549- Compiler now generates simpler and faster code for dictionary
3550 literals. The oparg for BUILD_MAP now indicates an estimated
3551 dictionary size. There is a new opcode, STORE_MAP, for adding
3552 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003553
Georg Brandl3ee81df2008-05-17 18:14:43 +00003554- Issue #1638: %zd configure test fails on Linux.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003562- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003563 SystemError.
3564
Nick Coghlanef01d822007-12-03 12:55:17 +00003565- PEP 366: Allow explicit relative imports when executing modules
3566 inside packages with the -m switch via a new module level
3567 __package__ attribute.

3570 running, and if the deallocation of its frames somehow calls the
3571 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003572

3582 file can now be directly executed by passing their name to the
3583 interpreter. The directory/zipfile is automatically inserted as the
3584 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003585
Georg Brandl3ee81df2008-05-17 18:14:43 +00003586- Issue #1265: Fix a problem with sys.settrace, if the tracing
3587 function uses a generator expression when at the same time the
3588 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003589
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003590- sets and frozensets now have an isdisjoint() method.
3591
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003592- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00003594- Fix warnings found by the new version of the Coverity checker.
3595
Georg Brandl3ee81df2008-05-17 18:14:43 +00003596- The enumerate() builtin function is no longer bounded to sequences
3597 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3598 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003599
Georg Brandl3ee81df2008-05-17 18:14:43 +00003600- Issue #1686386: Tuple's tp_repr did not take into account the
3601 possibility of having a self-referential tuple, which is possible
3602 from C code. Nor did object's tp_str consider that a type's tp_str
3603 could do something that could lead to an inifinite recursion.
3604 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3605 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003606
Georg Brandl3ee81df2008-05-17 18:14:43 +00003607- Issue #1164: It was possible to trigger deadlock when using the
3608 'print' statement to write to a file since the GIL was not released
3609 as needed. Now PyObject_Print() does the right thing along with
3610 various tp_print implementations of the built-in types and those in
3611 the collections module.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003613- Issue #1147: Exceptions were directly allowing string exceptions in
3614 their throw() method even though string exceptions no longer
3615 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003616
Georg Brandl3ee81df2008-05-17 18:14:43 +00003617- Issue #1096: Prevent a segfault from getting the repr of a very
3618 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003619
Brett Cannon1e534b52007-09-07 04:18:30 +00003620- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003621 PyObject_Call() never calling back out to Python code to trigger
3622 recursion depth updates/checks. Required the creation of a static
3623 RuntimeError instance in case normalizing an exception put the
3624 recursion check value past its limit. Fixes crashers
3625 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003626

Neal Norwitz0ac60192007-05-27 04:08:54 +00003640- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003641 __*__ attributes. (Some already existed, e.g., __doc__ and
3642 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003643
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003644- Add -3 option to the interpreter to warn about features that are
3645 deprecated and will be changed/removed in Python 3.0.
3646

3648 calls.
3649
Collin Winter62903052007-05-18 23:11:24 +00003650- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003651 "except E as target:". This is to provide forwards compatibility
3652 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003653
Brett Cannon229cee22007-05-05 01:34:02 +00003654- Deprecate BaseException.message as per PEP 352.
3655
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003657 inherited from a builtin base.
3658
Vinay Sajip8549ce32007-05-06 17:53:37 +00003659- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003660 setting a plain string, ie don't expand to single letter identifiers.
3661
Raymond Hettinger13936692007-04-11 18:40:58 +00003662- Request #1191699: Slices can now be pickled.
3663
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003664- Request #1193128: str.translate() now allows a None argument for
3665 translations that only remove characters without re-mapping the
3666 remaining characters.
3667
Georg Brandl5cb76c12007-03-21 09:00:39 +00003668- Patch #1682205: a TypeError while unpacking an iterable is no longer
3669 masked by a generic one with the message "unpack non-sequence".
3670
Neal Norwitzaa754b72007-03-21 06:39:48 +00003671- Remove unused file Python/fmod.c.
3672
Guido van Rossum143b5642007-03-23 04:58:42 +00003673- Bug #1683368: The object.__init__() and object.__new__() methods are
3674 now stricter in rejecting excess arguments. The only time when
3675 either allows excess arguments is when it is not overridden and the
3676 other one is. For backwards compatibility, when both are
3677 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003678 warning later). Also, type.__init__() insists on the same signature
3679 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3682 object to complex using its __complex__() method before falling back
3683 to the __float__() method. Therefore, the functions in the cmath
3684 module now can operate on objects that define a __complex__()
3685 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003686
Georg Brandl3ee81df2008-05-17 18:14:43 +00003687- Patch #1623563: allow __class__ assignment for classes with
3688 __slots__. The old and the new class are still required to have the
3689 same slot names.

3695 ``object.__reduce_ex__()`` is called with an object that is faking
3696 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003697
Georg Brandl3ee81df2008-05-17 18:14:43 +00003698- Patch #1680015: Don't modify __slots__ tuple if it contains an

3702
Georg Brandl7b9c5552007-03-12 14:30:05 +00003703- Bug #1678647: write a newline after printing an exception in any
3704 case, even when converting the value to a string failed.
3705
Georg Brandl871f1bc2007-03-12 13:17:36 +00003706- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003707 its argument, if it exists. If not, it will work like before. This
3708 allows customizing the output of dir() in the presence of a
3709 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003710
Collin Winter276887b2007-03-12 16:11:39 +00003711- Patch #922167: Python no longer segfaults when faced with infinitely
3712 self-recursive reload() calls (as reported by bug #742342).
3713

3718 parthensized forms. This means complex(repr(x)) now works instead of
3719 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003720
Georg Brandlaa2321b2007-03-07 00:40:28 +00003721- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003722 makes the filenames the warning module prints much more sensible
3723 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003724
Georg Brandl49aafc92007-03-07 00:34:46 +00003725- Variant of patch #697613: don't exit the interpreter on a SystemExit
3726 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003727 variable is given, but break into the interactive interpreter just
3728 like on other exceptions or normal program exit.

3734 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003735
Georg Brandl0fca97a2007-03-05 22:28:08 +00003736- Patch #1674228: when assigning a slice (old-style), check for the
3737 sq_ass_slice instead of the sq_slice slot.
3738
Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- When printing an unraisable error, don't print exceptions. before
3740 the name. This duplicates the behavior whening normally printing
3741 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003749- Bug #1377858: Fix the segfaulting of the interpreter when an object
3750 created a weakref on itself during a __del__ call for new-style
3751 classes (classic classes still have the bug).

4350 Python would crash instead of raising an error.
4351
Thomas Hellerc2f77252007-03-09 19:21:28 +00004352- Bug #1646630: ctypes.string_at(buf, 0) and ctypes.wstring_at(buf, 0)
4353 returned string up to the first NUL character.

4364
Georg Brandl3ee81df2008-05-17 18:14:43 +00004365- unittest now verifies more of its assumptions. In particular,
4366 TestCase and TestSuite subclasses (not instances) are no longer
4367 accepted in TestSuite.addTest(). This should cause no
4368 incompatibility since it never made sense with ordinary subclasses
4369 -- the failure just occurred later, with a more cumbersome
4370 exception.

4654 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00004655
Georg Brandl3ee81df2008-05-17 18:14:43 +00004656- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00004657 that the SMTP.starttls() caller no longer needs to call ehlo()
4658 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00004659 does not claim to support starttls. Adds the
4660 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

4741 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4742 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00004759 time so that opening a database previously created with the DB_DUP
4760 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4761 opens. Specifically: dictionary assignment to a DB object will
4762 replace all values for a given key when the database allows
4763 duplicate values. DB users should use DB.put(k, v) when they want
4764 to store duplicates; not DB[k] = v.

4771 characters with ASCII value less than 32. Also, it correctly quotes
4772 dots only if they occur on a single line, as opposed to the previous
4773 behavior of quoting dots if they are the second character of any
4774 line.

5097-----
5098
Georg Brandl3ee81df2008-05-17 18:14:43 +00005099- Unified naming convention for free lists and their limits. All free
5100 lists in Object/ are named ``free_list``, the counter ``numfree``
5101 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
5102 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00005103
Georg Brandl3ee81df2008-05-17 18:14:43 +00005104- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
5105 to ``PyTuple_SetItem``, it can be used to populate a brand new
5106 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00005107
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005108- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005110- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
5111 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
5112 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005113
5114- Patch #1720595: add T_BOOL to the range of structmember types.
5115
5116- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
5117 ``PyFloat_GetInfo()`` to the float API.
5118
Georg Brandl3ee81df2008-05-17 18:14:43 +00005119- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
5120 of w# format code incorrectly truncated the length to an int, even
5121 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5122 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005123
Georg Brandl3ee81df2008-05-17 18:14:43 +00005124- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
5125 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005126
Georg Brandl3ee81df2008-05-17 18:14:43 +00005127- PEP 3123: Provide forward compatibility with Python 3.0, while
5128 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
5129 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005130
Georg Brandl3ee81df2008-05-17 18:14:43 +00005131- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
5132 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00005133
5134- Patch #1733960: Allow T_LONGLONG to accept ints.
5135
5136- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
5137

5141
5142- Fix some leftovers from the conversion from int to Py_ssize_t
5143 (relevant to strings and sequences of more than 2**31 items).
5144
5145- Make _PyGILState_NoteThreadState() static, it was not used anywhere
5146 outside of pystate.c and should not be necessary.
5147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
5149 absolute imports. In earlier versions they might have used relative
5150 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00005151
Georg Brandl3ee81df2008-05-17 18:14:43 +00005152- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5153 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00005154
Georg Brandl3ee81df2008-05-17 18:14:43 +00005155- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
5156 macro so it can be used as an expression.

5161
Georg Brandl3ee81df2008-05-17 18:14:43 +00005162- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
5163 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
5164 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
5165 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00005166
Georg Brandl3ee81df2008-05-17 18:14:43 +00005167- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and

Georg Brandl3ee81df2008-05-17 18:14:43 +00005180- Removed the macfs module. It had been deprecated since Python 2.5.
5181 This lead to the deprecation of macostools.touched() as it relied
5182 solely on macfs and was a no-op under OS X.
