52 and read operations on write-only file objects. On Windows, the system C
53 library would return a bogus result; on Solaris, it was possible to crash
54 the interpreter. Patch by Stefan Krah.

70 suite_mask, and product_type.
71
Antoine Pitroue80a6a42010-01-17 12:26:20 +000072- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
73 could crash in many places because of the PyByteArray_AS_STRING() macro
74 returning NULL. The macro now returns a statically allocated empty
75 string instead.

86 some values large enough to cause overflow, and (4) a number of
87 flaws that could lead to incorrectly rounded results.

107 allowed by the XML specification, and are necessary when outputting e.g.
108 PHP code in a processing instruction. Patch by Neil Muller.

124 file position when calling `truncate()`. It would previously change the
125 file position to the given argument, which goes against the tradition of
126 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000144- Issue #7748: Since unicode values are supported for some metadata options
145 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
146 encoded string for them. This ensure that the upload and register commands
147 send the right values to PyPI without any error.
148
R. David Murrayed44dfa2010-01-16 05:15:17 +0000149- Issue #1670765: Prevent email.generator.Generator from re-wrapping

232
Mark Dickinson1b34d252010-01-01 17:27:30 +0000233- Issue #5080: A number of functions and methods previously produced a
234 DeprecationWarning when passed a float argument where an integer was
235 expected. These functions and methods now raise TypeError instead.
236 The majority of the effects of this change are in the extension
237 modules, but some core functions and methods are affected: notably
238 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
239 methods.
240
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000241- Issue #7604: Deleting an unset slotted attribute did not raise an

249
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000250- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
251 used to drop the time part of the result.
252
Mark Dickinson46572832009-12-27 14:55:57 +0000253- Issue #1811: improve accuracy and cross-platform consistency for
254 true division of integers: the result of a/b is now correctly
255 rounded for ints a and b (at least on IEEE 754 platforms), and in
256 particular does not depend on the internal representation of a long.
257
Ezio Melottif84caf42009-12-24 22:25:17 +0000258- Issue #6108: unicode(exception) and str(exception) should return the same

Benjamin Petersonddd392c2009-12-13 19:19:07 +0000325- Issue #7349: Make methods of file objects in the io module accept None as an
326 argument where file-like objects (ie StringIO and BytesIO) accept them to mean
327 the same as passing no argument.
328
Benjamin Petersonc4771d22009-12-13 17:31:31 +0000329- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

354 PyArg_VaParseTupleAndKeywords and PyArg_Parse no longer accept float
355 arguments for integer format codes (other than 'L'): previously an
356 attempt to pass a float resulted in a DeprecationWarning; now it
357 gives a TypeError. For the 'L' format code (which previously had no
358 warning) there is now a DeprecationWarning.

Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000403- Issue #7419: setlocale() could crash the interpreter on Windows when called
404 with invalid values.
405
Eric Smithc4ab8332009-11-29 17:40:57 +0000406- Issue #3382: 'F' formatting for float and complex now convert the
407 result to upper case. This only affects 'inf' and 'nan', since 'f'
408 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000409
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000410- Remove switch from "%f" formatting to "%g" formatting for floats
411 larger than 1e50 in absolute value.
412
Mark Dickinson18cfada2009-11-23 18:46:41 +0000413- Remove restrictions on precision when formatting floats. E.g.,
414 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
415 requested 120 significant digits instead.
416
Benjamin Peterson89b1a5c2009-11-19 22:58:01 +0000417- Add Py3k warnings for parameter names in parenthesis.

Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000421- Issue #7085: Fix crash when importing some extensions in a thread
422 on MacOSX 10.6.
423
Mark Dickinsonb678de82009-11-19 18:41:49 +0000424- Issue #7117: repr(x) for a float x returns a result based on the
425 shortest decimal string that's guaranteed to round back to x under
426 correct rounding (with round-half-to-even rounding mode).
427 Previously it gave a string based on rounding x to 17 decimal digits.
428 repr(x) for a complex number behaves similarly. On platforms where
429 the correctly-rounded strtod and dtoa code is not supported (see below),
430 repr is unchanged.
431
432- Issue #7117: On almost all platforms: float-to-string and
433 string-to-float conversions within Python are now correctly rounded.
434 Places these conversions occur include: str for floats and complex
435 numbers; the float and complex constructors; old-style and new-style
436 numeric formatting; serialization and deserialization of floats and
437 complex numbers using marshal, pickle and json; parsing of float and
438 imaginary literals in Python code; Decimal-to-float conversion.
439
440 The conversions use a Python-adapted version of David Gay's
441 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
442 functions. This code is supported on Windows, and on Unix-like
443 platforms using gcc, icc or suncc as the C compiler. There may be a
444 small number of platforms on which correct operation of this code
445 cannot be guaranteed, so the code is not used: notably, this applies
446 to platforms where the C double format is not IEEE 754 binary64, and
447 to platforms on x86 hardware where the x87 FPU is set to 64-bit
448 precision and Python's configure script is unable to determine how
449 to change the FPU precision. On these platforms conversions use the
450 platform strtod and dtoa, as before.
451
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000452- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000453 now uses the correctly-rounded string <-> float conversions
454 described above (when available), and so produces correctly rounded
455 results that will display nicely under the float repr. There are
456 two related small changes: (1) round now accepts any class with an
457 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000458 floats for the second argument), and (2) an excessively large second
459 integer argument (e.g., round(1.234, 10**100)) no longer raises an
460 exception.

607
Eric Smitha985a3a2009-05-05 18:26:08 +0000608- Issue #5920: For float.__format__, change the behavior with the
609 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
610 to be like 'g' but with at least one decimal point and with a
611 default precision of 12. Previously, the behavior the same but with
612 a default precision of 6. This more closely matches str(), and
613 reduces surprises when adding alignment flags to the empty
614 presentation type. This also affects the new complex.__format__ in
615 the same way.

678
Antoine Pitrouf8387af2009-03-23 18:41:45 +0000679- Issue #4688: Add a heuristic so that tuples and dicts containing only
680 untrackable objects are not tracked by the garbage collector. This can
681 reduce the size of collections and therefore the garbage collection overhead
682 on long-running programs, depending on their particular use of datatypes.

686 are now between 50% and 150% faster.
687
Mark Dickinsonefc82f72009-03-20 15:51:55 +0000688- Issue #4258: Make it possible to use base 2**30 instead of base
689 2**15 for the internal representation of integers, for performance
690 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
691 --enable-big-digits option to configure, which overrides the
692 default. Add sys.long_info structseq to provide information about
693 the internal format.
694
Benjamin Peterson6ffe8522009-03-18 20:52:15 +0000695- Issue #4034: Fix weird attribute error messages of the traceback object. (As a

704
Brett Cannon6c4cff02009-03-11 04:51:06 +0000705- Issue #3652: Make the 'line' argument for warnings.showwarning() a

707
Eric Smithe9fb6862009-02-20 14:02:36 +0000708- Issue #5247: Improve error message when unknown format codes are

710 float arguments.
711
Raymond Hettinger08259e82009-02-18 23:10:19 +0000712- Running Python with the -3 option now also warns about classic division
713 for ints and longs.
714
Mark Dickinson2ffb26f2009-02-15 10:13:41 +0000715- Issue #5260: Long integers now consume less memory: average
716 saving is 2 bytes per long on a 32-bit system and 6 bytes per long
717 on a 64-bit system.
718
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000719- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

724
Benjamin Petersone18ef192009-01-20 14:21:16 +0000725- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
726
Georg Brandl29c6a282009-04-05 20:23:13 +0000727- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000728 were suppressing all exceptions. These include list(), filter(), map(),
729 zip(), and bytearray().
730
Benjamin Peterson596d3062009-01-19 15:42:23 +0000731- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os
732 functions.
733
Benjamin Peterson5848d1f2009-01-19 00:08:08 +0000734- Issue #4991: Passing invalid file descriptors to io.FileIO now raises an

Antoine Pitrouc2f02212009-01-13 23:13:52 +0000739- Issue #4935: The overflow checking code in the expandtabs() method common
740 to str, bytes and bytearray could be optimized away by the compiler, letting
741 the interpreter segfault instead of raising an error.
742
Amaury Forgeot d'Arca40d5732009-01-12 23:36:55 +0000743- Issue #3720: Fix a crash when an iterator modifies its class and removes its

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000750- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
751 collecting the oldest generation) so that allocating lots of objects without
752 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000753 Martin von Löwis at

757
Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000758- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
759 an existing .py counterpart, override the co_filename attributes of all
760 code objects if the original filename is obsolete (which can happen if the
761 file has been renamed, moved, or if it is accessed through different paths).
762 Patch by Ziga Seilnacht and Jean-Paul Calderone.
763
Martin v. Löwis5344c992009-01-02 20:32:55 +0000764- Issue #4075: Use OutputDebugStringW in Py_FatalError.

771
Nick Coghlan180e4002008-12-30 01:18:48 +0000772- Issue #4701: PyObject_Hash now implicitly calls PyType_Ready on types
773 where the tp_hash and tp_dict slots are both NULL.
774
Benjamin Peterson7af65562008-12-29 17:56:58 +0000775- Issue #4764: With io.open, IOError.filename is set when trying to open a

783
Skip Montanarof205c132008-12-23 03:30:15 +0000784- Added test case to ensure attempts to read from a file opened for writing
785 fail.
786
Antoine Pitrou73c0e652008-12-17 22:46:54 +0000787- Issue #2467: gc.DEBUG_STATS reported invalid elapsed times. Also, always

800 exceptions.
801
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000802- Issue #4445: Replace "sizeof(PyStringObject)" with
803 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
804 str instances. On a typical machine this saves 3 bytes of memory
805 (on average) per string allocation.
806
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000807- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
808 interpreter to abort ("Fatal Python error: Could not reset the stack!")
809 instead of throwing a MemoryError.
810
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000811- Issue #3689: The list reversed iterator now supports __length_hint__

816
Vinay Sajip213faca2008-12-03 23:22:58 +0000817- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000818 method on file objects with closefd=False. The file descriptor is still
819 kept open but the file object behaves like a closed file. The ``FileIO``
820 object also got a new readonly attribute ``closefd``.
821
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000822- Issue #4348: Some bytearray methods returned that didn't cause any change to

836
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000837- Issue #4209: Enabling unicode_literals and the print_function in the same
838 __future__ import didn't work.
839
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000840- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000841 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000843- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
844 returned a path longer than MAX_PATH. (But It's doubtful this code path is
845 really executed because I cannot move to such directory on win2k)
846
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000847- Issue #4069: When set.remove(element) is used with a set element, the element
848 is temporarily replaced with an equivalent frozenset. But the eventual
849 KeyError would always report the empty frozenset([]) as the missing key. Now
850 it correctly refers to the initial element.

868 returned them on 64bit platforms.
869
Walter Dörwalded960ac2009-05-03 22:36:33 +0000870- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
871 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
872 step. This avoids problems with counting UTF-8 bytes that ignores the effect
873 of using the replace error handler in PyUnicode_DecodeUTF8().
874
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000875- Issue #3739: The unicode-internal encoder now reports the number of characters

877
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000878- Issue #2422: When compiled with the ``--with-valgrind`` option, the
879 pymalloc allocator will be automatically disabled when running under
880 Valgrind. This gives improved memory leak detection when running
881 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00002117- Issue #7222: Make thread "reaping" more reliable so that reference
2118 leak-chasing test runs give sensible results. The previous method of

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002263- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2264 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2265 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2266 ``printf`` function, whereas PyString_FromFormat has an independent
2267 implementation and uses "%zd" on all platforms for size_t values.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002284- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002285 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002286 was correctly parsed but parsing of subsequent arguments failed.
2287
Vinay Sajip35e3b032008-09-01 14:33:59 +00002288- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002289 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2290 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2291 when given a tuple of classes as second argument, were looking up
2292 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2293 type object.
2294
Neal Norwitz18aa3882008-08-24 05:04:52 +00002295- Fix crashes on memory allocation failure found with failmalloc.

2364 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2365 for catch_warnings() also led to an improvement in the raising of a
2366 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002432What's New in Python 2.6 beta 3?
2433================================
2434
Barry Warsaw07a4a382008-08-21 01:15:08 +00002435*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002436
2437Core and Builtins
2438-----------------
2439
Guido van Rossumf8402962008-08-20 15:01:50 +00002440- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2441 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2442 extensions do not automatically benefit from the class attribute
2443 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2444 to their tp_flags field if they care. This is a backwards
2445 compatibility feature; in 3.0, all types will use the cache by
2446 default.
2447
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002448- Keyword arguments can now follow starred arguments. (``f(a, *args,
2449 keyword=23)`` is now valid syntax.)
2450
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002451- ctypes function pointers that are COM methods have a boolean True
2452 value again.
2453
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002454- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2455 by denying s# to parse objects that have a releasebuffer procedure,
2456 and introducing s*.
2457
Georg Brandl1e13ea92008-08-11 09:07:59 +00002458- Issue #3537: Fix an assertion failure when an empty but presized dict
2459 object was stored in the freelist.
2460
Mark Dickinsonb6467572008-08-04 21:30:09 +00002461- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2462 ValueError consistently across platforms.
2463
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002464- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2465 (64bit Unix, for example), unichr() would truncate its argument and return
2466 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2467
Neal Norwitze7d8be82008-07-31 17:17:14 +00002468- Apply security patches from Apple.
2469
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002470- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2471 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2472
Antoine Pitrou92f82162008-07-25 22:22:08 +00002473- Issue #1819: function calls with several named parameters are now on
2474 average 35% faster (as measured by pybench).
2475
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002476- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2477 the python debugger steps into a class statement: the free variables (local
2478 variables defined in an outer scope) would be deleted from the outer scope.
2479
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002480- Issue #2620: Overflow checking when allocating or reallocating memory
2481 was not always being done properly in some python types and extension
2482 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2483 all been updated to perform better checks and places in the code that
2484 would previously leak memory on the error path when such an allocation
2485 failed have been fixed.

2489
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002490- Issue #3612: Added some missing basic types in ctypes.wintypes.
2491
Benjamin Petersone977ad42008-08-20 01:42:01 +00002492- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2493 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2494
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002495- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2496 version reported by these tools does not necessarily follow the python
2497 version numbering scheme, so the module is less strict when parsing it.
2498
Nick Coghlanf70385a2008-08-18 12:42:46 +00002499- Issue #2235: Added Py3k warnings for types which will become unhashable
2500 under the stricter __hash__ inheritance rules in 3.0. Several types
2501 which did not meet the rules for hash invariants and were already
2502 unhashable in 3.0 have now been explicitly flagged as unhashable in
2503 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2504 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2505
Brett Cannon88f801d2008-08-18 00:46:22 +00002506- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2507 imported into the module but exposed as part of the module's API.
2508
Brett Cannon7b96f072008-08-18 00:41:11 +00002509- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2510
Brett Cannon46225e72008-08-18 00:36:52 +00002511- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002513- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2514
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002515- Issue #3575: Incremental decoder's decode function now takes bytearray
2516 by using 's*' instead of 't#'.
2517
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002518- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002519 fails unicode conversion on 2nd parameter. (windows only)
2520
Facundo Batista94f243a2008-08-17 03:38:39 +00002521- Issue 2464. urllib2 now supports a malformation in the URL received
2522 in a redirect.
2523
Brett Cannonabe423e2008-08-16 21:47:07 +00002524- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002525 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002526
Facundo Batistaeb90b782008-08-16 14:44:07 +00002527- Issue #2776: fixed small issue when handling an URL with double slash
2528 after a 302 response in the case of not going through a proxy.
2529
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002530- Issue #2676: in the email package, content-type parsing was hanging on
2531 pathological input because of quadratic or exponential behaviour of a
2532 regular expression.
2533
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002534- Issue #3476: binary buffered reading through the new "io" library is now
2535 thread-safe.
2536
Brett Cannonbf3157b2008-08-14 05:00:03 +00002537- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2538 since mimetools itself is deprecated. Because modules are cached, all
2539 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2540
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002541- Issue #3134: shutil referenced undefined WindowsError symbol.
2542
Robert Schuppenies14646332008-08-10 11:01:53 +00002543- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2544 menu entries were not deleted.
2545
Brett Cannon83e81842008-08-09 23:30:55 +00002546- Copied the implementation of reduce() to _functools.reduce() to have a
2547 version that did not raise a DeprecationWarning under -3.
2548
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002549- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2550 a MemoryError rather than silently stop the iteration.
2551
Guido van Rossum59ce9012008-08-09 14:55:34 +00002552- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2553 to _sre.compile() will now be rejected. This should not affect anybody
2554 since the re.compile() function never generates invalid re-bytecode.
2555
Skip Montanaroa032bf42008-08-08 22:52:51 +00002556- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2557 upon first access it can be automatically initialized from the csv file if
2558 it wasn't initialized during instantiation.
2559
Brett Cannon3aa2a492008-08-06 22:28:09 +00002560- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2561 the reload() built-in has been removed.
2562
Brett Cannon7e30b672008-08-04 21:52:25 +00002563- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002564 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002575 asking for a specific length. This problem only affected files opened

2632-----------------
2633
Georg Brandl3e483f62008-07-16 22:57:41 +00002634- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2635 its methods now allow for items objects that can be converted to
2636 an integer using operator.index().
2637
Mark Dickinson64b7e502008-07-16 09:40:03 +00002638- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2639 produced a ValueError instead of giving the correct float.
2640
Eric Smitha5fa5a22008-07-16 00:11:49 +00002641- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2642 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2643
Mark Dickinson7103aa42008-07-15 19:08:33 +00002644- Issue #3008: the float type has a new instance method 'float.hex'
2645 and a new class method 'float.fromhex' to convert floating-point
2646 numbers to and from hexadecimal strings, respectively.
2647
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002648- Issue #2235: __hash__ is once again inherited by default. To allow
2649 collections.Hashable to remain meaningful in the presence of the
2650 default hash implementation (object.__hash__), it is now possible
2651 to explicit block inheritance of hash by setting __hash__=None at
2652 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2653 level.
2654
Nick Coghlanb028f502008-07-13 14:52:36 +00002655- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2656 the parent module cannot be found while performing an absolute import.
2657 This means that an incorrectly defined __package__ attribute will
2658 now only prevent relative imports in that module rather than causing
2659 all imports from that module to fail.
2660
Nick Coghlan14ff9942008-07-08 14:21:42 +00002661- Issue #2517: Allow unicode messages in Exceptions again by correctly

2671 another thread's dictionary.
2672
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002673- Issue #3004: Minor change to slice.indices(): the start and stop
2674 arguments are now treated identically, making the behaviour easier
2675 to describe and understand. For example, slice(None, -10,
2676 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2677 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2678 10, -1).
2679
Georg Brandl278fc502008-07-19 12:46:12 +00002680- Issue #3219: Calling a function with repeated keyword arguments,
2681 f(a=2, a=23), would not cause a syntax error. This was a regression
2682 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00002684- Issue #2862: Make int and float freelist management consistent with
2685 other freelists. Changes their CompactFreeList apis into

2693 error when they failed.
2694
Martin v. Löwisaabf4042008-08-02 07:20:25 +00002695- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002720- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2721 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002722 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002723 content-length. The problem had been corrected in the 2.4 branch, but never
2724 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002739- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
2740 handling is now the same as that of other special attributes like __name__).
2741

3149
Georg Brandl74a1dea2008-05-28 11:21:39 +00003150- Add ``PyType_Modified()`` as a public API to clear the type cache.
3151
3152- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003153
3154- The PyString functions have been renamed to PyBytes. A batch of
3155 defines were added so that the linker still sees the original
3156 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003194- Issue #1631171: Re-implement the 'warnings' module in C (the
3195 original Python code has been kept as backup). This will allow for
3196 using the 'warning's machinery in such places as the parser where
3197 use of pure Python code is not possible. Both the ``showarning()``
3198 and ``formatwarning()`` gain an optional 'line' argument which is
3199 not called by default for backwards-compatibility reasons. Setting
3200 ``warnings.showwarning()`` to an implementation that lacks support
3201 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003243- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003244 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003264- Issue #2550: The approach used by client/server code for obtaining
3265 ports to listen on in network-oriented tests has been refined in an
3266 effort to facilitate running multiple instances of the entire
3267 regression test suite in parallel without issue.
3268 test_support.bind_port() has been fixed such that it will always
3269 return a unique port -- which wasn't always the case with the
3270 previous implementation, especially if socket options had been set
3271 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3272 new implementation of bind_port() will actually raise an exception
3273 if it is passed an AF_INET/SOCK_STREAM socket with either the
3274 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3275 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3276 the socket it's been passed. This currently only applies to
3277 Windows. This option prevents any other sockets from binding to the
3278 host/port we've bound to, thus removing the possibility of the
3279 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3280 when a second SOCK_STREAM socket binds and accepts to a host/port
3281 that's already been bound by another socket. The optional preferred
3282 port parameter to bind_port() has been removed. Under no
3283 circumstances should tests be hard coding ports!
3284
3285 test_support.find_unused_port() has also been introduced, which will
3286 pass a temporary socket object to bind_port() in order to obtain an
3287 unused port. The temporary socket object is then closed and
3288 deleted, and the port is returned. This method should only be used
3289 for obtaining an unused port in order to pass to an external program
3290 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3291 a parameter to a server-oriented class that doesn't give you direct
3292 access to the underlying socket used.
3293
3294 Finally, test_support.HOST has been introduced, which should be used
3295 for the host argument of any relevant socket calls (i.e. bind and
3296 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003297
3298 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003299 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003300 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3301 test_asynchat and test_socket_ssl.
3302
Georg Brandl3ee81df2008-05-17 18:14:43 +00003303 It is now possible for multiple instances of the regression test
3304 suite to run in parallel without issue.

3571-----------------
3572
Fred Drakea8ee94b2008-03-01 02:45:07 +00003573- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003574 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00003579
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003580- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003581 issue 215555 for a discussion.
3582
Eric Smitha73fbe72008-02-23 03:09:44 +00003583- Added the future_builtins module, which contains hex() and oct().
3584 These are the PEP 3127 version of these functions, designed to be
3585 compatible with the hex() and oct() builtins from Python 3.0. They
3586 differ slightly in their output formats from the existing, unchanged
3587 Python 2.6 builtins. The expected usage of the future_builtins
3588 module is:
3589 from future_builtins import hex, oct
3590
Eric Smith7ef40bf2008-02-20 23:34:22 +00003591- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3592 exponents for exponents with absolute value < 100. Follows C99
3593 standard. This is a change on Windows, which would use 3 digits.
3594 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3595 so that any alterations it does to the resulting string will be
3596 available in stringlib/formatter.h (for float.__format__).
3597
Eric Smith5a3c1352008-02-19 13:21:56 +00003598- Implemented PEP 3101, Advanced String Formatting. This adds a new
3599 builtin format(); a format() method for str and unicode; a
3600 __format__() method to object, str, unicode, int, long, float, and
3601 datetime; the class string.Formatter; and the C API
3602 PyObject_Format().
3603
Georg Brandl3ee81df2008-05-17 18:14:43 +00003604- Fixed several potential crashes, all caused by specially crafted
3605 __del__ methods exploiting objects in temporarily inconsistent
3606 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003607
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003608- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003609 prevent a possible crash: an Abstract Base Class would try to access
3610 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003615- Clear all free lists during a gc.collect() of the highest generation
3616 in order to allow pymalloc to free more arenas. Python may give back
3617 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003618
Georg Brandl3ee81df2008-05-17 18:14:43 +00003619- Issue #2045: Fix an infinite recursion triggered when printing a
3620 subclass of collections.defaultdict, if its default_factory is set
3621 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003622
Christian Heimesf75dbef2008-02-08 00:11:31 +00003623- Fixed a minor memory leak in dictobject.c. The content of the free
3624 list was not freed on interpreter shutdown.
3625
Georg Brandl3ee81df2008-05-17 18:14:43 +00003626- Limit free list of method and builtin function objects to 256
3627 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3630 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003631 to compact the internal free lists of pre-allocted ints and floats.
3632
Georg Brandl3ee81df2008-05-17 18:14:43 +00003633- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3634 calls. Python expected the return type int but the fork familie
3635 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003636
Georg Brandl3ee81df2008-05-17 18:14:43 +00003637- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003649- Patch #1473257: generator objects gain a gi_code attribute. This is
3650 the same object as the func_code attribute of the function that
3651 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003652
Georg Brandl3ee81df2008-05-17 18:14:43 +00003653- Issue #1920: "while 0" statements were completely removed by the
3654 compiler, even in the presence of an "else" clause, which is
3655 supposed to be run when the condition is false. Now the compiler

Guido van Rossumeead05f2008-01-24 18:21:02 +00003658- A few crashers fixed: weakref_in_del.py (issue #1377858);
3659 loosing_dict_ref.py (issue #1303614, test67.py);
3660 borrowed_ref_[34].py (not in tracker).
3661
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003662- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003663 suppressed while an extension is loaded by calling SetErrorMode in
3664 dynload_win.c. The error is still reported properly.
3665
Georg Brandl3ee81df2008-05-17 18:14:43 +00003666- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003667 several extension methods and modules do not work without unicode
3668 support.
3669
Georg Brandl26543b12008-01-21 18:36:51 +00003670- Issue #1882: when compiling code from a string, encoding cookies in the
3671 second line of code were not always recognized correctly.
3672
Georg Brandl14404b62008-01-19 19:27:05 +00003673- Issue #1679: "0x" was taken as a valid integer literal.
3674
Georg Brandl6caad7d2008-01-26 14:19:22 +00003675- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003676 added.
3677
Christian Heimesc94e2b52008-01-14 04:13:37 +00003678- sys.float_info / PyFloat_GetInfo: The floating point information
3679 object was converted from a dict to a specialized structseq object.
3680
Georg Brandl3ee81df2008-05-17 18:14:43 +00003681- Patch #1816: Added sys.flags structseq. It exposes the status of
3682 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003683
Georg Brandl3ee81df2008-05-17 18:14:43 +00003684- Objects/structseq.c: Implemented new structseq representation. The
3685 patch makes structseqs (e.g. the return value of os.stat) more
3686 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003687
Georg Brandl3ee81df2008-05-17 18:14:43 +00003688- Patch #1700288: added a type attribute cache that caches method
3689 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003690
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003691- Bug #1776: __import__() no longer accepts filenames on any platform.
3692 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003693
Georg Brandlaed6c662008-01-07 17:25:53 +00003694- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3695
Georg Brandl3ee81df2008-05-17 18:14:43 +00003696- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3697 envvar and sys.dont_write_bytecode attribute. All these can be set
3698 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003699
Georg Brandl3ee81df2008-05-17 18:14:43 +00003700- Improve some exception messages when Windows fails to load an
3701 extension module. Now we get for example '%1 is not a valid Win32
3702 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003703
Georg Brandl3ee81df2008-05-17 18:14:43 +00003704- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003706- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3707 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003708
Christian Heimes0a8143f2007-12-18 23:22:54 +00003709- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003710 and INF. float("nan"), float("inf") and float("-inf") now work on
3711 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003712
Georg Brandl3ee81df2008-05-17 18:14:43 +00003713- Compiler now generates simpler and faster code for dictionary
3714 literals. The oparg for BUILD_MAP now indicates an estimated
3715 dictionary size. There is a new opcode, STORE_MAP, for adding
3716 entries to the dictionary.

3734 running, and if the deallocation of its frames somehow calls the
3735 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003736

Georg Brandl3ee81df2008-05-17 18:14:43 +00003742- Issue #1460: The utf-7 incremental decoder did not accept truncated
3743 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003744
Georg Brandl3ee81df2008-05-17 18:14:43 +00003745- Patch #1739468: Directories and zipfiles containing a __main__.py
3746 file can now be directly executed by passing their name to the
3747 interpreter. The directory/zipfile is automatically inserted as the
3748 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003749
Georg Brandl3ee81df2008-05-17 18:14:43 +00003750- Issue #1265: Fix a problem with sys.settrace, if the tracing
3751 function uses a generator expression when at the same time the
3752 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003753
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003754- sets and frozensets now have an isdisjoint() method.
3755
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003756- optimize the performance of builtin.sum().
3757
Neal Norwitz44f326e2007-10-05 05:29:17 +00003758- Fix warnings found by the new version of the Coverity checker.
3759
Georg Brandl3ee81df2008-05-17 18:14:43 +00003760- The enumerate() builtin function is no longer bounded to sequences
3761 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3762 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003763
Georg Brandl3ee81df2008-05-17 18:14:43 +00003764- Issue #1686386: Tuple's tp_repr did not take into account the
3765 possibility of having a self-referential tuple, which is possible
3766 from C code. Nor did object's tp_str consider that a type's tp_str
3767 could do something that could lead to an inifinite recursion.
3768 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3769 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003770
Georg Brandl3ee81df2008-05-17 18:14:43 +00003771- Issue #1164: It was possible to trigger deadlock when using the
3772 'print' statement to write to a file since the GIL was not released
3773 as needed. Now PyObject_Print() does the right thing along with
3774 various tp_print implementations of the built-in types and those in
3775 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003776
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777- Issue #1147: Exceptions were directly allowing string exceptions in
3778 their throw() method even though string exceptions no longer
3779 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003780
Georg Brandl3ee81df2008-05-17 18:14:43 +00003781- Issue #1096: Prevent a segfault from getting the repr of a very
3782 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003783
Brett Cannon1e534b52007-09-07 04:18:30 +00003784- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003785 PyObject_Call() never calling back out to Python code to trigger
3786 recursion depth updates/checks. Required the creation of a static
3787 RuntimeError instance in case normalizing an exception put the
3788 recursion check value past its limit. Fixes crashers
3789 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003790
Georg Brandl3ee81df2008-05-17 18:14:43 +00003791- Patch #1031213: Decode source line in SyntaxErrors back to its

3795 with %G.
3796
Georg Brandl3ee81df2008-05-17 18:14:43 +00003797- Prevent expandtabs() on string and unicode objects from causing a
3798 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00003804- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003805 __*__ attributes. (Some already existed, e.g., __doc__ and
3806 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003807
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003808- Add -3 option to the interpreter to warn about features that are
3809 deprecated and will be changed/removed in Python 3.0.
3810
Georg Brandl2134e752007-05-21 20:34:16 +00003811- Patch #1686487: you can now pass any mapping after '**' in function
3812 calls.
3813
Collin Winter62903052007-05-18 23:11:24 +00003814- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003815 "except E as target:". This is to provide forwards compatibility
3816 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003817
Brett Cannon229cee22007-05-05 01:34:02 +00003818- Deprecate BaseException.message as per PEP 352.
3819
Georg Brandl3ee81df2008-05-17 18:14:43 +00003820- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003821 inherited from a builtin base.
3822
Vinay Sajip8549ce32007-05-06 17:53:37 +00003823- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003824 setting a plain string, ie don't expand to single letter identifiers.
3825
Raymond Hettinger13936692007-04-11 18:40:58 +00003826- Request #1191699: Slices can now be pickled.
3827
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003828- Request #1193128: str.translate() now allows a None argument for
3829 translations that only remove characters without re-mapping the
3830 remaining characters.
3831
Georg Brandl5cb76c12007-03-21 09:00:39 +00003832- Patch #1682205: a TypeError while unpacking an iterable is no longer
3833 masked by a generic one with the message "unpack non-sequence".
3834
Neal Norwitzaa754b72007-03-21 06:39:48 +00003835- Remove unused file Python/fmod.c.
3836
Guido van Rossum143b5642007-03-23 04:58:42 +00003837- Bug #1683368: The object.__init__() and object.__new__() methods are
3838 now stricter in rejecting excess arguments. The only time when
3839 either allows excess arguments is when it is not overridden and the
3840 other one is. For backwards compatibility, when both are
3841 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003842 warning later). Also, type.__init__() insists on the same signature
3843 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003844
Georg Brandl3ee81df2008-05-17 18:14:43 +00003845- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3846 object to complex using its __complex__() method before falling back
3847 to the __float__() method. Therefore, the functions in the cmath
3848 module now can operate on objects that define a __complex__()
3849 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003850
Georg Brandl3ee81df2008-05-17 18:14:43 +00003851- Patch #1623563: allow __class__ assignment for classes with
3852 __slots__. The old and the new class are still required to have the
3853 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003854
Georg Brandl3ee81df2008-05-17 18:14:43 +00003855- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00003858- Patch #1462488: Python no longer segfaults when
3859 ``object.__reduce_ex__()`` is called with an object that is faking
3860 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003861
Georg Brandl3ee81df2008-05-17 18:14:43 +00003862- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00003865- Patch #1444529: the builtin compile() now accepts keyword arguments.
3866
Georg Brandl7b9c5552007-03-12 14:30:05 +00003867- Bug #1678647: write a newline after printing an exception in any
3868 case, even when converting the value to a string failed.
3869
Georg Brandl871f1bc2007-03-12 13:17:36 +00003870- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003871 its argument, if it exists. If not, it will work like before. This
3872 allows customizing the output of dir() in the presence of a
3873 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003874
Collin Winter276887b2007-03-12 16:11:39 +00003875- Patch #922167: Python no longer segfaults when faced with infinitely
3876 self-recursive reload() calls (as reported by bug #742342).
3877
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00003881- Patch #1491866: change the complex() constructor to allow
3882 parthensized forms. This means complex(repr(x)) now works instead of
3883 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003884
Georg Brandlaa2321b2007-03-07 00:40:28 +00003885- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886 makes the filenames the warning module prints much more sensible
3887 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003888
Georg Brandl49aafc92007-03-07 00:34:46 +00003889- Variant of patch #697613: don't exit the interpreter on a SystemExit
3890 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003891 variable is given, but break into the interactive interpreter just
3892 like on other exceptions or normal program exit.

4391
Georg Brandlfb4b3b72007-04-24 15:27:13 +00004392- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
4393 (as opposed to the command line) will now write file names ending in
4394 ".cpp" too.
4395
Facundo Batistad918a652007-04-24 13:54:38 +00004396- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004397 the client's request was successfully received, understood, and
4398 accepted. Now in these cases no error is raised in urllib (issue
4399 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004400
Georg Brandl3ee81df2008-05-17 18:14:43 +00004401- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004407- Added a timeout parameter to the constructor of other protocols
4408 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4409 work started with create_connection() and timeout in httplib, and
4410 closes patch #723312.
4411
Vinay Sajip8549ce32007-05-06 17:53:37 +00004412- Patch #1676823: Added create_connection() to socket.py, which may be
4413 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004414 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004415
Martin v. Löwis0af33882007-03-23 13:27:15 +00004416- Bug #978833: Revert r50844, as it broke _socketobject.dup.
4417

Georg Brandl3ee81df2008-05-17 18:14:43 +00004423- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
4424 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00004425 directories.
4426

4436
Georg Brandlf66b6032007-03-14 08:27:52 +00004437- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004438 AttributeError instead of an IOError when the server's response
4439 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004440
Georg Brandl3ee81df2008-05-17 18:14:43 +00004441- Patch #957650: "%var%" environment variable references are now
4442 properly expanded in ntpath.expandvars(), also "~user" home
4443 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00004444
Georg Brandl3ee81df2008-05-17 18:14:43 +00004445- Patch #1429539: pdb now correctly initializes the __main__ module
4446 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004447 correctly now.
4448
Georg Brandlbad6f192007-03-13 21:32:56 +00004449- The nonobvious commands.getstatus() function is now deprecated.

4455
Georg Brandl3ee81df2008-05-17 18:14:43 +00004456- Patch #1530482: add pydoc.render_doc() which returns the
4457 documentation for a thing instead of paging it to stdout, which
4458 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004459
Georg Brandl3ee81df2008-05-17 18:14:43 +00004460- Patch #1533909: the timeit module now accepts callables in addition

4466 parameter which can be set to False to prevent the default
4467 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004468
Georg Brandl9e6b4702007-03-13 18:15:41 +00004469- Patch #1581073: add a flag to textwrap that prevents the dropping of
4470 whitespace while wrapping.
4471
Georg Brandl92a6bae2007-03-13 17:43:32 +00004472- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004473 are set for invalid interpolation sequences that would lead to
4474 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00004475

4488
Georg Brandl94fe3f52007-03-13 09:32:11 +00004489- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00004490 field names in its exception message if you try to write a record
4491 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00004509
Andrew M. Kuchlinge45a77a2008-01-19 16:26:13 +00004510- Patch #742598: Add .timeout attribute to SocketServer that calls

4517 returned string up to the first NUL character.

4528
Georg Brandl3ee81df2008-05-17 18:14:43 +00004529- unittest now verifies more of its assumptions. In particular,
4530 TestCase and TestSuite subclasses (not instances) are no longer
4531 accepted in TestSuite.addTest(). This should cause no
4532 incompatibility since it never made sense with ordinary subclasses
4533 -- the failure just occurred later, with a more cumbersome
4534 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004535

4543 given a unicode argument and os.listdir() returns unicode filenames.
4544
Georg Brandl3ee81df2008-05-17 18:14:43 +00004545- Patch #1673619: setup.py identifies extension modules it doesn't
4546 know how to build and those it knows how to build but that fail to
4547 build.

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00004922- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00004923 time so that opening a database previously created with the DB_DUP
4924 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4925 opens. Specifically: dictionary assignment to a DB object will
4926 replace all values for a given key when the database allows
4927 duplicate values. DB users should use DB.put(k, v) when they want
4928 to store duplicates; not DB[k] = v.

4935 characters with ASCII value less than 32. Also, it correctly quotes
4936 dots only if they occur on a single line, as opposed to the previous
4937 behavior of quoting dots if they are the second character of any
4938 line.
