92 file position when calling `truncate()`. It would previously change the
93 file position to the given argument, which goes against the tradition of
94 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
95
Benjamin Petersone06f7112010-01-28 02:15:02 +000096- UserDict is now a new-style class.

99 :class:`zipfile.ZipExtFile` class used to represent files stored inside
100 an archive. The new implementation is significantly faster and can
101 be wrapped in a :class:`io.BufferedReader` object for more speedups.
102 It also solves an issue where interleaved calls to `read()` and
103 `readline()` give wrong results. Patch by Nir Aides.

113 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
114 encoded string for them. This ensure that the upload and register commands
115 send the right values to PyPI without any error.
116
R. David Murrayed44dfa2010-01-16 05:15:17 +0000117- Issue #1670765: Prevent email.generator.Generator from re-wrapping

Antoine Pitrou5b7139a2010-01-02 21:12:58 +0000198- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
199 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
200
Mark Dickinson1b34d252010-01-01 17:27:30 +0000201- Issue #5080: A number of functions and methods previously produced a
202 DeprecationWarning when passed a float argument where an integer was
203 expected. These functions and methods now raise TypeError instead.
204 The majority of the effects of this change are in the extension
205 modules, but some core functions and methods are affected: notably
206 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
207 methods.
208
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000209- Issue #7604: Deleting an unset slotted attribute did not raise an

217
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000218- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
219 used to drop the time part of the result.
220
Mark Dickinson46572832009-12-27 14:55:57 +0000221- Issue #1811: improve accuracy and cross-platform consistency for
222 true division of integers: the result of a/b is now correctly
223 rounded for ints a and b (at least on IEEE 754 platforms), and in
224 particular does not depend on the internal representation of a long.
225
Ezio Melottif84caf42009-12-24 22:25:17 +0000226- Issue #6108: unicode(exception) and str(exception) should return the same

228
Ronald Oussoren92919a62009-12-24 13:30:58 +0000229- Issue #6834: replace the implementation for the 'python' and 'pythonw'
230 executables on OSX.
231

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000293- Issue #7349: Make methods of file objects in the io module accept None as an
294 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
295 the same as passing no argument.
296
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000297- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

Mark Dickinson1b34d252010-01-01 17:27:30 +0000320- Issue #5080: The argument parsing functions PyArg_ParseTuple,
321 PyArg_ParseTupleAndKeywords, PyArg_VaParse,
322 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
323 arguments for integer format codes (other than 'L'): previously an
324 attempt to pass a float resulted in a DeprecationWarning; now it
325 gives a TypeError. For the 'L' format code (which previously had no
326 warning) there is now a DeprecationWarning.

373
Eric Smithc4ab8332009-11-29 17:40:57 +0000374- Issue #3382: 'F' formatting for float and complex now convert the
375 result to upper case. This only affects 'inf' and 'nan', since 'f'
376 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000377

382 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
383 requested 120 significant digits instead.

390 on MacOSX 10.6.
391
Mark Dickinsonb678de82009-11-19 18:41:49 +0000392- Issue #7117: repr(x) for a float x returns a result based on the
393 shortest decimal string that's guaranteed to round back to x under
394 correct rounding (with round-half-to-even rounding mode).
395 Previously it gave a string based on rounding x to 17 decimal digits.
396 repr(x) for a complex number behaves similarly. On platforms where
397 the correctly-rounded strtod and dtoa code is not supported (see below),
398 repr is unchanged.
399
400- Issue #7117: On almost all platforms: float-to-string and
401 string-to-float conversions within Python are now correctly rounded.
402 Places these conversions occur include: str for floats and complex
403 numbers; the float and complex constructors; old-style and new-style
404 numeric formatting; serialization and deserialization of floats and
405 complex numbers using marshal, pickle and json; parsing of float and
406 imaginary literals in Python code; Decimal-to-float conversion.
407
408 The conversions use a Python-adapted version of David Gay's
409 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
410 functions. This code is supported on Windows, and on Unix-like
411 platforms using gcc, icc or suncc as the C compiler. There may be a
412 small number of platforms on which correct operation of this code
413 cannot be guaranteed, so the code is not used: notably, this applies
414 to platforms where the C double format is not IEEE 754 binary64, and
415 to platforms on x86 hardware where the x87 FPU is set to 64-bit
416 precision and Python's configure script is unable to determine how
417 to change the FPU precision. On these platforms conversions use the
418 platform strtod and dtoa, as before.
419
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000420- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000421 now uses the correctly-rounded string <-> float conversions
422 described above (when available), and so produces correctly rounded
423 results that will display nicely under the float repr. There are
424 two related small changes: (1) round now accepts any class with an
425 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000426 floats for the second argument), and (2) an excessively large second
427 integer argument (e.g., round(1.234, 10**100)) no longer raises an
428 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000576- Issue #5920: For float.__format__, change the behavior with the
577 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
578 to be like 'g' but with at least one decimal point and with a
579 default precision of 12. Previously, the behavior the same but with
580 a default precision of 6. This more closely matches str(), and
581 reduces surprises when adding alignment flags to the empty
582 presentation type. This also affects the new complex.__format__ in
583 the same way.

649 reduce the size of collections and therefore the garbage collection overhead
650 on long-running programs, depending on their particular use of datatypes.

657 2**15 for the internal representation of integers, for performance
658 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
659 --enable-big-digits option to configure, which overrides the

694
Georg Brandl29c6a282009-04-05 20:23:13 +0000695- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000696 were suppressing all exceptions. These include list(), filter(), map(),
697 zip(), and bytearray().
698
Benjamin Peterson596d3062009-01-19 15:42:23 +0000699- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000726- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
727 an existing .py counterpart, override the co_filename attributes of all
728 code objects if the original filename is obsolete (which can happen if the
729 file has been renamed, moved, or if it is accessed through different paths).
730 Patch by Ziga Seilnacht and Jean-Paul Calderone.

768 exceptions.
769
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000770- Issue #4445: Replace "sizeof(PyStringObject)" with
771 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
772 str instances. On a typical machine this saves 3 bytes of memory
773 (on average) per string allocation.
774
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000775- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

777 instead of throwing a MemoryError.
778
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000779- Issue #3689: The list reversed iterator now supports __length_hint__

784
Vinay Sajip213faca2008-12-03 23:22:58 +0000785- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000786 method on file objects with closefd=False. The file descriptor is still
787 kept open but the file object behaves like a closed file. The ``FileIO``
788 object also got a new readonly attribute ``closefd``.
789
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000790- Issue #4348: Some bytearray methods returned that didn't cause any change to

804
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000805- Issue #4209: Enabling unicode_literals and the print_function in the same
806 __future__ import didn't work.
807
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000808- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000809 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000811- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
812 returned a path longer than MAX_PATH. (But It's doubtful this code path is
813 really executed because I cannot move to such directory on win2k)
814
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000815- Issue #4069: When set.remove(element) is used with a set element, the element
816 is temporarily replaced with an equivalent frozenset. But the eventual
817 KeyError would always report the empty frozenset([]) as the missing key. Now
818 it correctly refers to the initial element.

836 returned them on 64bit platforms.
837
Walter Dörwalded960ac2009-05-03 22:36:33 +0000838- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
839 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
840 step. This avoids problems with counting UTF-8 bytes that ignores the effect
841 of using the replace error handler in PyUnicode_DecodeUTF8().
842
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000843- Issue #3739: The unicode-internal encoder now reports the number of characters
844 consumed like any other encoder (instead of the number of bytes).
845
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000846- Issue #2422: When compiled with the ``--with-valgrind`` option, the
847 pymalloc allocator will be automatically disabled when running under
848 Valgrind. This gives improved memory leak detection when running
849 under Valgrind, while taking advantage of pymalloc at other times.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002231- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2232 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2233 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2234 ``printf`` function, whereas PyString_FromFormat has an independent
2235 implementation and uses "%zd" on all platforms for size_t values.
2236 This makes a difference on win64, where ``printf`` needs "%Id" to display

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002254 was correctly parsed but parsing of subsequent arguments failed.
2255
Vinay Sajip35e3b032008-09-01 14:33:59 +00002256- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to

2260 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2261 type object.

2332 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2333 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002400What's New in Python 2.6 beta 3?
2401================================
2402
Barry Warsaw07a4a382008-08-21 01:15:08 +00002403*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002404
2405Core and Builtins
2406-----------------
2407
Guido van Rossumf8402962008-08-20 15:01:50 +00002408- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2409 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2410 extensions do not automatically benefit from the class attribute
2411 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2412 to their tp_flags field if they care. This is a backwards
2413 compatibility feature; in 3.0, all types will use the cache by
2414 default.
2415
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002416- Keyword arguments can now follow starred arguments. (``f(a, *args,
2417 keyword=23)`` is now valid syntax.)
2418
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002419- ctypes function pointers that are COM methods have a boolean True
2420 value again.
2421
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002422- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2423 by denying s# to parse objects that have a releasebuffer procedure,
2424 and introducing s*.
2425
Georg Brandl1e13ea92008-08-11 09:07:59 +00002426- Issue #3537: Fix an assertion failure when an empty but presized dict
2427 object was stored in the freelist.
2428
Mark Dickinsonb6467572008-08-04 21:30:09 +00002429- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2430 ValueError consistently across platforms.
2431
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002432- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2433 (64bit Unix, for example), unichr() would truncate its argument and return
2434 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2435
Neal Norwitze7d8be82008-07-31 17:17:14 +00002436- Apply security patches from Apple.
2437
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002438- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2439 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2440
Antoine Pitrou92f82162008-07-25 22:22:08 +00002441- Issue #1819: function calls with several named parameters are now on
2442 average 35% faster (as measured by pybench).
2443
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002444- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2445 the python debugger steps into a class statement: the free variables (local
2446 variables defined in an outer scope) would be deleted from the outer scope.
2447
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002448- Issue #2620: Overflow checking when allocating or reallocating memory
2449 was not always being done properly in some python types and extension
2450 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2451 all been updated to perform better checks and places in the code that
2452 would previously leak memory on the error path when such an allocation
2453 failed have been fixed.

2457
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002458- Issue #3612: Added some missing basic types in ctypes.wintypes.
2459
Benjamin Petersone977ad42008-08-20 01:42:01 +00002460- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2461 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2462
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002463- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2464 version reported by these tools does not necessarily follow the python
2465 version numbering scheme, so the module is less strict when parsing it.
2466
Nick Coghlanf70385a2008-08-18 12:42:46 +00002467- Issue #2235: Added Py3k warnings for types which will become unhashable
2468 under the stricter __hash__ inheritance rules in 3.0. Several types
2469 which did not meet the rules for hash invariants and were already
2470 unhashable in 3.0 have now been explicitly flagged as unhashable in
2471 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2472 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2473
Brett Cannon88f801d2008-08-18 00:46:22 +00002474- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

2476
Brett Cannon7b96f072008-08-18 00:41:11 +00002477- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2478
Brett Cannon46225e72008-08-18 00:36:52 +00002479- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002481- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2482
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002483- Issue #3575: Incremental decoder's decode function now takes bytearray
2484 by using 's*' instead of 't#'.
2485
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002486- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002487 fails unicode conversion on 2nd parameter. (windows only)
2488
Facundo Batista94f243a2008-08-17 03:38:39 +00002489- Issue 2464. urllib2 now supports a malformation in the URL received
2490 in a redirect.
2491
Brett Cannonabe423e2008-08-16 21:47:07 +00002492- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002493 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002494
Facundo Batistaeb90b782008-08-16 14:44:07 +00002495- Issue #2776: fixed small issue when handling an URL with double slash
2496 after a 302 response in the case of not going through a proxy.
2497
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002498- Issue #2676: in the email package, content-type parsing was hanging on
2499 pathological input because of quadratic or exponential behaviour of a
2500 regular expression.
2501
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002502- Issue #3476: binary buffered reading through the new "io" library is now
2503 thread-safe.
2504
Brett Cannonbf3157b2008-08-14 05:00:03 +00002505- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2506 since mimetools itself is deprecated. Because modules are cached, all
2507 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2508
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002509- Issue #3134: shutil referenced undefined WindowsError symbol.
2510
Robert Schuppenies14646332008-08-10 11:01:53 +00002511- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2512 menu entries were not deleted.
2513
Brett Cannon83e81842008-08-09 23:30:55 +00002514- Copied the implementation of reduce() to _functools.reduce() to have a
2515 version that did not raise a DeprecationWarning under -3.
2516
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002517- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2518 a MemoryError rather than silently stop the iteration.
2519
Guido van Rossum59ce9012008-08-09 14:55:34 +00002520- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2521 to _sre.compile() will now be rejected. This should not affect anybody
2522 since the re.compile() function never generates invalid re-bytecode.
2523
Skip Montanaroa032bf42008-08-08 22:52:51 +00002524- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2525 upon first access it can be automatically initialized from the csv file if
2526 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002528- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2529 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +00002543 asking for a specific length. This problem only affected files opened
2544 using the new "io" module, not the built-in open() function.

2572
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002573- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

2596
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002597*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00002599Core and Builtins
2600-----------------
2601
Georg Brandl3e483f62008-07-16 22:57:41 +00002602- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2603 its methods now allow for items objects that can be converted to
2604 an integer using operator.index().
2605
Mark Dickinson64b7e502008-07-16 09:40:03 +00002606- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2607 produced a ValueError instead of giving the correct float.
2608
Eric Smitha5fa5a22008-07-16 00:11:49 +00002609- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2610 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2611
Mark Dickinson7103aa42008-07-15 19:08:33 +00002612- Issue #3008: the float type has a new instance method 'float.hex'
2613 and a new class method 'float.fromhex' to convert floating-point
2614 numbers to and from hexadecimal strings, respectively.
2615
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002616- Issue #2235: __hash__ is once again inherited by default. To allow
2617 collections.Hashable to remain meaningful in the presence of the
2618 default hash implementation (object.__hash__), it is now possible
2619 to explicit block inheritance of hash by setting __hash__=None at
2620 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2621 level.
2622
Nick Coghlanb028f502008-07-13 14:52:36 +00002623- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2624 the parent module cannot be found while performing an absolute import.
2625 This means that an incorrectly defined __package__ attribute will
2626 now only prevent relative imports in that module rather than causing
2627 all imports from that module to fail.
2628
Nick Coghlan14ff9942008-07-08 14:21:42 +00002629- Issue #2517: Allow unicode messages in Exceptions again by correctly
2630 bypassing the instance dictionary when looking up __unicode__ on
2631 new-style classes.
2632
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00002633- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
2634 set to a custom object whose write() method happens to install
2635 another file in sys.stdout.
2636
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00002637- Issue #3088: Corrected a race condition in classes derived from
2638 threading.local: the first member set by a thread could be saved in
2639 another thread's dictionary.
2640
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002641- Issue #3004: Minor change to slice.indices(): the start and stop
2642 arguments are now treated identically, making the behaviour easier
2643 to describe and understand. For example, slice(None, -10,
2644 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2645 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2646 10, -1).
2647
Georg Brandl278fc502008-07-19 12:46:12 +00002648- Issue #3219: Calling a function with repeated keyword arguments,
2649 f(a=2, a=23), would not cause a syntax error. This was a regression
2650 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00002651
Georg Brandl278fc502008-07-19 12:46:12 +00002652- Issue #2862: Make int and float freelist management consistent with
2653 other freelists. Changes their CompactFreeList apis into
2654 ClearFreeList apis and calls them via gc.collect().

2658
Thomas Heller57adf222008-08-14 19:10:48 +00002659- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
2660 api functions without holding the GIL, which could lead to a fatal
2661 error when they failed.
2662
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002663- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

2672 ForkingPickler.register() to resolve conflict with ctypes.
2673
Vinay Sajip51e65192008-07-18 09:01:10 +00002674- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00002675
Thomas Heller880f5292008-07-15 19:39:38 +00002676- Issue #3313: Fixed a crash when a failed dlopen() call does not set
2677 a valid dlerror() message.

2685
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002686- Issue #3301: Bisect module behaved badly when lo was negative.
Raymond Hettinger3cd1e422008-07-10 14:03:19 +00002687
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002688- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2689 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002690 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002691 content-length. The problem had been corrected in the 2.4 branch, but never
2692 merged into trunk.
2693
Georg Brandle78fbcc2008-07-05 10:13:36 +00002694- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002707- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2708 handling is now the same as that of other special attributes like __name__).
2709
Brett Cannon8bb8fa52008-07-02 01:57:08 +00002710- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3166 and ``formatwarning()`` gain an optional 'line' argument which is
3167 not called by default for backwards-compatibility reasons. Setting
3168 ``warnings.showwarning()`` to an implementation that lacks support
3169 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003232- Issue #2550: The approach used by client/server code for obtaining
3233 ports to listen on in network-oriented tests has been refined in an
3234 effort to facilitate running multiple instances of the entire
3235 regression test suite in parallel without issue.
3236 test_support.bind_port() has been fixed such that it will always
3237 return a unique port -- which wasn't always the case with the
3238 previous implementation, especially if socket options had been set
3239 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3240 new implementation of bind_port() will actually raise an exception
3241 if it is passed an AF_INET/SOCK_STREAM socket with either the
3242 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3243 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3244 the socket it's been passed. This currently only applies to
3245 Windows. This option prevents any other sockets from binding to the
3246 host/port we've bound to, thus removing the possibility of the
3247 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3248 when a second SOCK_STREAM socket binds and accepts to a host/port
3249 that's already been bound by another socket. The optional preferred
3250 port parameter to bind_port() has been removed. Under no
3251 circumstances should tests be hard coding ports!
3252
3253 test_support.find_unused_port() has also been introduced, which will
3254 pass a temporary socket object to bind_port() in order to obtain an
3255 unused port. The temporary socket object is then closed and
3256 deleted, and the port is returned. This method should only be used
3257 for obtaining an unused port in order to pass to an external program
3258 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3259 a parameter to a server-oriented class that doesn't give you direct
3260 access to the underlying socket used.
3261
3262 Finally, test_support.HOST has been introduced, which should be used
3263 for the host argument of any relevant socket calls (i.e. bind and
3264 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003265
3266 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003267 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003268 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3269 test_asynchat and test_socket_ssl.
3270
Georg Brandl3ee81df2008-05-17 18:14:43 +00003271 It is now possible for multiple instances of the regression test
3272 suite to run in parallel without issue.

3540
Fred Drakea8ee94b2008-03-01 02:45:07 +00003541- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003542 644. The mode is now inherited from the py file.

3550
Eric Smitha73fbe72008-02-23 03:09:44 +00003551- Added the future_builtins module, which contains hex() and oct().
3552 These are the PEP 3127 version of these functions, designed to be
3553 compatible with the hex() and oct() builtins from Python 3.0. They
3554 differ slightly in their output formats from the existing, unchanged
3555 Python 2.6 builtins. The expected usage of the future_builtins
3556 module is:
3557 from future_builtins import hex, oct
3558
Eric Smith7ef40bf2008-02-20 23:34:22 +00003559- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3560 exponents for exponents with absolute value < 100. Follows C99
3561 standard. This is a change on Windows, which would use 3 digits.
3562 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3563 so that any alterations it does to the resulting string will be
3564 available in stringlib/formatter.h (for float.__format__).
3565
Eric Smith5a3c1352008-02-19 13:21:56 +00003566- Implemented PEP 3101, Advanced String Formatting. This adds a new
3567 builtin format(); a format() method for str and unicode; a
3568 __format__() method to object, str, unicode, int, long, float, and
3569 datetime; the class string.Formatter; and the C API
3570 PyObject_Format().
3571
Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- Fixed several potential crashes, all caused by specially crafted
3573 __del__ methods exploiting objects in temporarily inconsistent
3574 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003575
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003576- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003577 prevent a possible crash: an Abstract Base Class would try to access
3578 a slot on a registered virtual subclass.

3585 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003586
Georg Brandl3ee81df2008-05-17 18:14:43 +00003587- Issue #2045: Fix an infinite recursion triggered when printing a

3598 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003599 to compact the internal free lists of pre-allocted ints and floats.
3600
Georg Brandl3ee81df2008-05-17 18:14:43 +00003601- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3602 calls. Python expected the return type int but the fork familie
3603 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003617- Patch #1473257: generator objects gain a gi_code attribute. This is
3618 the same object as the func_code attribute of the function that
3619 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003620
Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Issue #1920: "while 0" statements were completely removed by the
3622 compiler, even in the presence of an "else" clause, which is
3623 supposed to be run when the condition is false. Now the compiler
3624 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003625

Georg Brandl3ee81df2008-05-17 18:14:43 +00003652- Objects/structseq.c: Implemented new structseq representation. The
3653 patch makes structseqs (e.g. the return value of os.stat) more
3654 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003655
Georg Brandl3ee81df2008-05-17 18:14:43 +00003656- Patch #1700288: added a type attribute cache that caches method
3657 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003658
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003659- Bug #1776: __import__() no longer accepts filenames on any platform.
3660 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00003662- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3663
Georg Brandl3ee81df2008-05-17 18:14:43 +00003664- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3665 envvar and sys.dont_write_bytecode attribute. All these can be set
3666 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003667
Georg Brandl3ee81df2008-05-17 18:14:43 +00003668- Improve some exception messages when Windows fails to load an
3669 extension module. Now we get for example '%1 is not a valid Win32
3670 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003671

Christian Heimes0a8143f2007-12-18 23:22:54 +00003677- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003678 and INF. float("nan"), float("inf") and float("-inf") now work on
3679 every platform with IEEE 754 semantics.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Compiler now generates simpler and faster code for dictionary
3682 literals. The oparg for BUILD_MAP now indicates an estimated
3683 dictionary size. There is a new opcode, STORE_MAP, for adding
3684 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Patch #1739468: Directories and zipfiles containing a __main__.py
3714 file can now be directly executed by passing their name to the
3715 interpreter. The directory/zipfile is automatically inserted as the
3716 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003718- Issue #1265: Fix a problem with sys.settrace, if the tracing
3719 function uses a generator expression when at the same time the
3720 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003721
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003722- sets and frozensets now have an isdisjoint() method.

3725
Neal Norwitz44f326e2007-10-05 05:29:17 +00003726- Fix warnings found by the new version of the Coverity checker.
3727
Georg Brandl3ee81df2008-05-17 18:14:43 +00003728- The enumerate() builtin function is no longer bounded to sequences
3729 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3730 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003731
Georg Brandl3ee81df2008-05-17 18:14:43 +00003732- Issue #1686386: Tuple's tp_repr did not take into account the
3733 possibility of having a self-referential tuple, which is possible
3734 from C code. Nor did object's tp_str consider that a type's tp_str
3735 could do something that could lead to an inifinite recursion.
3736 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3737 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003738
Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Issue #1164: It was possible to trigger deadlock when using the
3740 'print' statement to write to a file since the GIL was not released
3741 as needed. Now PyObject_Print() does the right thing along with
3742 various tp_print implementations of the built-in types and those in
3743 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003744
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Issue #1147: Exceptions were directly allowing string exceptions in

3747 allowed.

Brett Cannona0c05512007-09-10 21:38:27 +00003751
Brett Cannon1e534b52007-09-07 04:18:30 +00003752- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003753 PyObject_Call() never calling back out to Python code to trigger
3754 recursion depth updates/checks. Required the creation of a static
3755 RuntimeError instance in case normalizing an exception put the
3756 recursion check value past its limit. Fixes crashers
3757 infinite_rec_(1|2|4|5).py.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003772- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773 __*__ attributes. (Some already existed, e.g., __doc__ and
3774 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003775
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003776- Add -3 option to the interpreter to warn about features that are
3777 deprecated and will be changed/removed in Python 3.0.
3778
Georg Brandl2134e752007-05-21 20:34:16 +00003779- Patch #1686487: you can now pass any mapping after '**' in function
3780 calls.
3781
Collin Winter62903052007-05-18 23:11:24 +00003782- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783 "except E as target:". This is to provide forwards compatibility
3784 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003785
Brett Cannon229cee22007-05-05 01:34:02 +00003786- Deprecate BaseException.message as per PEP 352.

3790
Vinay Sajip8549ce32007-05-06 17:53:37 +00003791- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003792 setting a plain string, ie don't expand to single letter identifiers.
3793
Raymond Hettinger13936692007-04-11 18:40:58 +00003794- Request #1191699: Slices can now be pickled.
3795
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003796- Request #1193128: str.translate() now allows a None argument for
3797 translations that only remove characters without re-mapping the
3798 remaining characters.
3799
Georg Brandl5cb76c12007-03-21 09:00:39 +00003800- Patch #1682205: a TypeError while unpacking an iterable is no longer
3801 masked by a generic one with the message "unpack non-sequence".
3802
Neal Norwitzaa754b72007-03-21 06:39:48 +00003803- Remove unused file Python/fmod.c.
3804
Guido van Rossum143b5642007-03-23 04:58:42 +00003805- Bug #1683368: The object.__init__() and object.__new__() methods are
3806 now stricter in rejecting excess arguments. The only time when
3807 either allows excess arguments is when it is not overridden and the
3808 other one is. For backwards compatibility, when both are
3809 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003810 warning later). Also, type.__init__() insists on the same signature
3811 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003812
Georg Brandl3ee81df2008-05-17 18:14:43 +00003813- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3814 object to complex using its __complex__() method before falling back
3815 to the __float__() method. Therefore, the functions in the cmath
3816 module now can operate on objects that define a __complex__()
3817 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003818
Georg Brandl3ee81df2008-05-17 18:14:43 +00003819- Patch #1623563: allow __class__ assignment for classes with
3820 __slots__. The old and the new class are still required to have the
3821 same slot names.

3834
Georg Brandl7b9c5552007-03-12 14:30:05 +00003835- Bug #1678647: write a newline after printing an exception in any
3836 case, even when converting the value to a string failed.
3837
Georg Brandl871f1bc2007-03-12 13:17:36 +00003838- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003839 its argument, if it exists. If not, it will work like before. This
3840 allows customizing the output of dir() in the presence of a
3841 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003842
Collin Winter276887b2007-03-12 16:11:39 +00003843- Patch #922167: Python no longer segfaults when faced with infinitely
3844 self-recursive reload() calls (as reported by bug #742342).
3845
Georg Brandl3ee81df2008-05-17 18:14:43 +00003846- Patch #1675981: remove unreachable code from ``type.__new__()``

3850 parthensized forms. This means complex(repr(x)) now works instead of
3851 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003852
Georg Brandlaa2321b2007-03-07 00:40:28 +00003853- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003854 makes the filenames the warning module prints much more sensible
3855 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003856
Georg Brandl49aafc92007-03-07 00:34:46 +00003857- Variant of patch #697613: don't exit the interpreter on a SystemExit
3858 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003859 variable is given, but break into the interactive interpreter just
3860 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00003868- Patch #1674228: when assigning a slice (old-style), check for the
3869 sq_ass_slice instead of the sq_slice slot.
3870
Georg Brandl3ee81df2008-05-17 18:14:43 +00003871- When printing an unraisable error, don't print exceptions. before
3872 the name. This duplicates the behavior whening normally printing
3873 exceptions.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004406 AttributeError instead of an IOError when the server's response
4407 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004408

Georg Brandl3ee81df2008-05-17 18:14:43 +00004413- Patch #1429539: pdb now correctly initializes the __main__ module
4414 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004415 correctly now.
4416

4423
Georg Brandl3ee81df2008-05-17 18:14:43 +00004424- Patch #1530482: add pydoc.render_doc() which returns the

4439
Georg Brandl92a6bae2007-03-13 17:43:32 +00004440- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004441 are set for invalid interpolation sequences that would lead to
4442 errors on reading back those values.

4485 returned string up to the first NUL character.

4496
Georg Brandl3ee81df2008-05-17 18:14:43 +00004497- unittest now verifies more of its assumptions. In particular,
4498 TestCase and TestSuite subclasses (not instances) are no longer
4499 accepted in TestSuite.addTest(). This should cause no
4500 incompatibility since it never made sense with ordinary subclasses
4501 -- the failure just occurred later, with a more cumbersome
4502 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004503

4512
Georg Brandl3ee81df2008-05-17 18:14:43 +00004513- Patch #1673619: setup.py identifies extension modules it doesn't

4862 contents before adding elements from the iterable. This fix brings
4863 the behavior into line with that for list.__init__().

4873 complex, tuple, list, dict, set, and frozenset. Formerly, it would
4874 silently miscode subclasses of those types. Now, it raises a
4875 ValueError instead.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004890- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004891 time so that opening a database previously created with the DB_DUP
4892 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4893 opens. Specifically: dictionary assignment to a DB object will
4894 replace all values for a given key when the database allows
4895 duplicate values. DB users should use DB.put(k, v) when they want
4896 to store duplicates; not DB[k] = v.

4903 characters with ASCII value less than 32. Also, it correctly quotes
4904 dots only if they occur on a single line, as opposed to the previous
4905 behavior of quoting dots if they are the second character of any
4906 line.

5252 of w# format code incorrectly truncated the length to an int, even
5253 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
5254 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005284- Added case insensitive comparison methods ``PyOS_stricmp(char*,
5285 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
