Antoine Pitroue80a6a42010-01-17 12:26:20 +000067- Issue #7561: Operations on empty bytearrays (such as `int(bytearray())`)
68 could crash in many places because of the PyByteArray_AS_STRING() macro
69 returning NULL. The macro now returns a statically allocated empty
70 string instead.

79 that occurred in debug builds when parsing certain long numeric
Mark Dickinson23df3d22010-01-17 13:37:57 +000080 strings corresponding to subnormal values, (3) a memory leak for
81 some values large enough to cause overflow, and (4) a number of
82 flaws that could lead to incorrectly rounded results.

116 file position when calling `truncate()`. It would previously change the
117 file position to the given argument, which goes against the tradition of
118 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
119
Benjamin Petersone06f7112010-01-28 02:15:02 +0000120- UserDict is now a new-style class.

123 :class:`zipfile.ZipExtFile` class used to represent files stored inside
124 an archive. The new implementation is significantly faster and can

134 the release file is empty.
135
Tarek Ziadéf14c7fc2010-01-24 00:33:32 +0000136- Issue #7748: Since unicode values are supported for some metadata options
137 in Distutils, the DistributionMetadata get_* methods will now return an utf-8
138 encoded string for them. This ensure that the upload and register commands
139 send the right values to PyPI without any error.
140
R. David Murrayed44dfa2010-01-16 05:15:17 +0000141- Issue #1670765: Prevent email.generator.Generator from re-wrapping

217-----------------
218
Benjamin Petersonecdae192010-01-04 00:43:01 +0000219- The __complex__ method is now looked up on the class of instances to make it

224
Mark Dickinson1b34d252010-01-01 17:27:30 +0000225- Issue #5080: A number of functions and methods previously produced a
226 DeprecationWarning when passed a float argument where an integer was
227 expected. These functions and methods now raise TypeError instead.
228 The majority of the effects of this change are in the extension
229 modules, but some core functions and methods are affected: notably
230 the 'chr', 'range' and 'xrange' builtins, and many unicode/str
231 methods.
232
Benjamin Peterson0f02d392009-12-30 19:34:10 +0000233- Issue #7604: Deleting an unset slotted attribute did not raise an

241
Amaury Forgeot d'Arc8645a5c2009-12-29 22:03:38 +0000242- Issue #7413: Passing '\0' as the separator to datetime.datetime.isoformat()
243 used to drop the time part of the result.
244
Mark Dickinson46572832009-12-27 14:55:57 +0000245- Issue #1811: improve accuracy and cross-platform consistency for
246 true division of integers: the result of a/b is now correctly
247 rounded for ints a and b (at least on IEEE 754 platforms), and in
248 particular does not depend on the internal representation of a long.
249
Ezio Melottif84caf42009-12-24 22:25:17 +0000250- Issue #6108: unicode(exception) and str(exception) should return the same

252
Ronald Oussoren92919a62009-12-24 13:30:58 +0000253- Issue #6834: replace the implementation for the 'python' and 'pythonw'

262
Benjamin Peterson4895af42009-12-13 16:36:53 +0000263- Issue #7491: Metaclass's __cmp__ method was ignored.
264
Antoine Pitrou2a08b422009-12-13 16:18:14 +0000265- Issue #7466: segmentation fault when the garbage collector is called

396 with invalid values.
397
Eric Smithc4ab8332009-11-29 17:40:57 +0000398- Issue #3382: 'F' formatting for float and complex now convert the
399 result to upper case. This only affects 'inf' and 'nan', since 'f'
400 no longer converts to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000401
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000402- Remove switch from "%f" formatting to "%g" formatting for floats

404
Mark Dickinson18cfada2009-11-23 18:46:41 +0000405- Remove restrictions on precision when formatting floats. E.g.,
406 "%.120g" % 1e-100 used to raise OverflowError, but now gives the
407 requested 120 significant digits instead.

414 on MacOSX 10.6.
415
Mark Dickinsonb678de82009-11-19 18:41:49 +0000416- Issue #7117: repr(x) for a float x returns a result based on the
417 shortest decimal string that's guaranteed to round back to x under
418 correct rounding (with round-half-to-even rounding mode).
419 Previously it gave a string based on rounding x to 17 decimal digits.
420 repr(x) for a complex number behaves similarly. On platforms where
421 the correctly-rounded strtod and dtoa code is not supported (see below),
422 repr is unchanged.
423
424- Issue #7117: On almost all platforms: float-to-string and
425 string-to-float conversions within Python are now correctly rounded.
426 Places these conversions occur include: str for floats and complex
427 numbers; the float and complex constructors; old-style and new-style
428 numeric formatting; serialization and deserialization of floats and
429 complex numbers using marshal, pickle and json; parsing of float and
430 imaginary literals in Python code; Decimal-to-float conversion.
431
432 The conversions use a Python-adapted version of David Gay's
433 well-known dtoa.c, providing correctly-rounded strtod and dtoa C
434 functions. This code is supported on Windows, and on Unix-like
435 platforms using gcc, icc or suncc as the C compiler. There may be a
436 small number of platforms on which correct operation of this code
437 cannot be guaranteed, so the code is not used: notably, this applies
438 to platforms where the C double format is not IEEE 754 binary64, and
439 to platforms on x86 hardware where the x87 FPU is set to 64-bit
440 precision and Python's configure script is unable to determine how
441 to change the FPU precision. On these platforms conversions use the
442 platform strtod and dtoa, as before.
443
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000444- Issue #7117: Backport round implementation from Python 3.x. round
Mark Dickinsonb678de82009-11-19 18:41:49 +0000445 now uses the correctly-rounded string <-> float conversions
446 described above (when available), and so produces correctly rounded
447 results that will display nicely under the float repr. There are
448 two related small changes: (1) round now accepts any class with an
449 __index__ method for its second argument (but no longer accepts
Mark Dickinsonbd15a062009-11-18 19:33:35 +0000450 floats for the second argument), and (2) an excessively large second
451 integer argument (e.g., round(1.234, 10**100)) no longer raises an
452 exception.

Eric Smitha985a3a2009-05-05 18:26:08 +0000600- Issue #5920: For float.__format__, change the behavior with the
601 empty presentation type (that is, not one of 'e', 'f', 'g', or 'n')
602 to be like 'g' but with at least one decimal point and with a
603 default precision of 12. Previously, the behavior the same but with
604 a default precision of 6. This more closely matches str(), and
605 reduces surprises when adding alignment flags to the empty
606 presentation type. This also affects the new complex.__format__ in
607 the same way.

681 2**15 for the internal representation of integers, for performance
682 reasons. Base 2**30 is enabled by default on 64-bit machines. Add
683 --enable-big-digits option to configure, which overrides the
684 default. Add sys.long_info structseq to provide information about
685 the internal format.

709 on a 64-bit system.
710
Antoine Pitrou76a4b892009-02-13 13:52:33 +0000711- Issue #5186: Reduce hash collisions for objects with no __hash__ method by

718
Georg Brandl29c6a282009-04-05 20:23:13 +0000719- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +0000720 were suppressing all exceptions. These include list(), filter(), map(),
721 zip(), and bytearray().
722
Benjamin Peterson596d3062009-01-19 15:42:23 +0000723- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Antoine Pitrou4c5ecb72009-01-09 21:40:55 +0000742- Issue #4074: Change the criteria for doing a full garbage collection (i.e.
743 collecting the oldest generation) so that allocating lots of objects without
744 destroying them does not show quadratic performance. Based on a proposal by
Benjamin Petersond50a5d52009-07-13 00:03:20 +0000745 Martin von Löwis at

Antoine Pitroue96d4ea2009-01-06 18:10:47 +0000750- Issue #1180193: When importing a module from a .pyc (or .pyo) file with
751 an existing .py counterpart, override the co_filename attributes of all
752 code objects if the original filename is obsolete (which can happen if the
753 file has been renamed, moved, or if it is accessed through different paths).
754 Patch by Ziga Seilnacht and Jean-Paul Calderone.

766
Benjamin Peterson7af65562008-12-29 17:56:58 +0000767- Issue #4764: With io.open, IOError.filename is set when trying to open a

775
Skip Montanarof205c132008-12-23 03:30:15 +0000776- Added test case to ensure attempts to read from a file opened for writing
777 fail.
778

792 exceptions.
793
Mark Dickinson826f3fe2008-12-05 21:55:28 +0000794- Issue #4445: Replace "sizeof(PyStringObject)" with
795 "offsetof(PyStringObject, ob_sval) + 1" when allocating memory for
796 str instances. On a typical machine this saves 3 bytes of memory
797 (on average) per string allocation.
798
Amaury Forgeot d'Arcdc619012008-11-22 20:01:18 +0000799- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

801 instead of throwing a MemoryError.
802
Raymond Hettinger7989a4d2008-12-03 15:42:10 +0000803- Issue #3689: The list reversed iterator now supports __length_hint__

Vinay Sajip213faca2008-12-03 23:22:58 +0000809- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Amaury Forgeot d'Arc32265652008-11-20 23:34:31 +0000810 method on file objects with closefd=False. The file descriptor is still
811 kept open but the file object behaves like a closed file. The ``FileIO``
812 object also got a new readonly attribute ``closefd``.
813
Benjamin Peterson46cc6d12008-11-19 21:49:09 +0000814- Issue #4348: Some bytearray methods returned that didn't cause any change to

828
Benjamin Petersonbdca9422008-10-26 20:21:13 +0000829- Issue #4209: Enabling unicode_literals and the print_function in the same
830 __future__ import didn't work.
831
Benjamin Peterson399b1fe2008-10-25 02:53:28 +0000832- Using ``nonlocal`` as a variable name will now raise a Py3k SyntaxWarning
Georg Brandl7fb00ad2008-10-25 07:00:52 +0000833 because it is a reserved word in 3.x.

Hirokazu Yamamoto10a018c2008-10-09 10:00:30 +0000835- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
836 returned a path longer than MAX_PATH. (But It's doubtful this code path is
837 really executed because I cannot move to such directory on win2k)
838
Amaury Forgeot d'Arcd78b9dc2008-10-07 20:32:10 +0000839- Issue #4069: When set.remove(element) is used with a set element, the element
840 is temporarily replaced with an equivalent frozenset. But the eventual
841 KeyError would always report the empty frozenset([]) as the missing key. Now
842 it correctly refers to the initial element.

Walter Dörwalded960ac2009-05-03 22:36:33 +0000862- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
863 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
864 step. This avoids problems with counting UTF-8 bytes that ignores the effect
865 of using the replace error handler in PyUnicode_DecodeUTF8().
866
Walter Dörwald726ba8e2009-05-06 14:32:35 +0000867- Issue #3739: The unicode-internal encoder now reports the number of characters

869
Benjamin Peterson91c12eb2009-12-03 02:52:39 +0000870- Issue #2422: When compiled with the ``--with-valgrind`` option, the
871 pymalloc allocator will be automatically disabled when running under
872 Valgrind. This gives improved memory leak detection when running
873 under Valgrind, while taking advantage of pymalloc at other times.

Antoine Pitrou59c44f32009-10-30 17:07:08 +00002109- Issue #7222: Make thread "reaping" more reliable so that reference
2110 leak-chasing test runs give sensible results. The previous method of
2111 reaping threads could return successfully while some Thread objects were

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002255- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2256 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2257 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2258 ``printf`` function, whereas PyString_FromFormat has an independent
2259 implementation and uses "%zd" on all platforms for size_t values.
2260 This makes a difference on win64, where ``printf`` needs "%Id" to display

Vinay Sajip35e3b032008-09-01 14:33:59 +00002280- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002281 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2282 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2283 when given a tuple of classes as second argument, were looking up
2284 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2285 type object.
2286
Neal Norwitz18aa3882008-08-24 05:04:52 +00002287- Fix crashes on memory allocation failure found with failmalloc.

2356 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2357 for catch_warnings() also led to an improvement in the raising of a
2358 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002424What's New in Python 2.6 beta 3?
2425================================
2426
Barry Warsaw07a4a382008-08-21 01:15:08 +00002427*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002428
2429Core and Builtins
2430-----------------
2431
Guido van Rossumf8402962008-08-20 15:01:50 +00002432- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2433 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2434 extensions do not automatically benefit from the class attribute
2435 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2436 to their tp_flags field if they care. This is a backwards
2437 compatibility feature; in 3.0, all types will use the cache by
2438 default.
2439
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002440- Keyword arguments can now follow starred arguments. (``f(a, *args,
2441 keyword=23)`` is now valid syntax.)
2442
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002443- ctypes function pointers that are COM methods have a boolean True
2444 value again.
2445
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002446- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2447 by denying s# to parse objects that have a releasebuffer procedure,
2448 and introducing s*.
2449
Georg Brandl1e13ea92008-08-11 09:07:59 +00002450- Issue #3537: Fix an assertion failure when an empty but presized dict
2451 object was stored in the freelist.
2452
Mark Dickinsonb6467572008-08-04 21:30:09 +00002453- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2454 ValueError consistently across platforms.
2455
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002456- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2457 (64bit Unix, for example), unichr() would truncate its argument and return
2458 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2459
Neal Norwitze7d8be82008-07-31 17:17:14 +00002460- Apply security patches from Apple.
2461
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002462- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2463 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2464
Antoine Pitrou92f82162008-07-25 22:22:08 +00002465- Issue #1819: function calls with several named parameters are now on
2466 average 35% faster (as measured by pybench).
2467
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002468- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2469 the python debugger steps into a class statement: the free variables (local
2470 variables defined in an outer scope) would be deleted from the outer scope.
2471
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002472- Issue #2620: Overflow checking when allocating or reallocating memory
2473 was not always being done properly in some python types and extension
2474 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2475 all been updated to perform better checks and places in the code that
2476 would previously leak memory on the error path when such an allocation
2477 failed have been fixed.

2481
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002482- Issue #3612: Added some missing basic types in ctypes.wintypes.
2483
Benjamin Petersone977ad42008-08-20 01:42:01 +00002484- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2485 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2486
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002487- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2488 version reported by these tools does not necessarily follow the python
2489 version numbering scheme, so the module is less strict when parsing it.
2490
Nick Coghlanf70385a2008-08-18 12:42:46 +00002491- Issue #2235: Added Py3k warnings for types which will become unhashable
2492 under the stricter __hash__ inheritance rules in 3.0. Several types
2493 which did not meet the rules for hash invariants and were already
2494 unhashable in 3.0 have now been explicitly flagged as unhashable in
2495 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2496 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2497
Brett Cannon88f801d2008-08-18 00:46:22 +00002498- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2499 imported into the module but exposed as part of the module's API.
2500
Brett Cannon7b96f072008-08-18 00:41:11 +00002501- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2502
Brett Cannon46225e72008-08-18 00:36:52 +00002503- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002505- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2506
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002507- Issue #3575: Incremental decoder's decode function now takes bytearray
2508 by using 's*' instead of 't#'.
2509
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002510- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002511 fails unicode conversion on 2nd parameter. (windows only)
2512
Facundo Batista94f243a2008-08-17 03:38:39 +00002513- Issue 2464. urllib2 now supports a malformation in the URL received
2514 in a redirect.
2515
Brett Cannonabe423e2008-08-16 21:47:07 +00002516- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002517 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002518
Facundo Batistaeb90b782008-08-16 14:44:07 +00002519- Issue #2776: fixed small issue when handling an URL with double slash
2520 after a 302 response in the case of not going through a proxy.
2521
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002522- Issue #2676: in the email package, content-type parsing was hanging on
2523 pathological input because of quadratic or exponential behaviour of a
2524 regular expression.
2525
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002526- Issue #3476: binary buffered reading through the new "io" library is now
2527 thread-safe.
2528
Brett Cannonbf3157b2008-08-14 05:00:03 +00002529- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2530 since mimetools itself is deprecated. Because modules are cached, all
2531 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2532
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002533- Issue #3134: shutil referenced undefined WindowsError symbol.
2534
Robert Schuppenies14646332008-08-10 11:01:53 +00002535- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2536 menu entries were not deleted.
2537
Brett Cannon83e81842008-08-09 23:30:55 +00002538- Copied the implementation of reduce() to _functools.reduce() to have a
2539 version that did not raise a DeprecationWarning under -3.
2540
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002541- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
2542 a MemoryError rather than silently stop the iteration.
2543
Guido van Rossum59ce9012008-08-09 14:55:34 +00002544- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
2545 to _sre.compile() will now be rejected. This should not affect anybody
2546 since the re.compile() function never generates invalid re-bytecode.
2547
Skip Montanaroa032bf42008-08-08 22:52:51 +00002548- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
2549 upon first access it can be automatically initialized from the csv file if
2550 it wasn't initialized during instantiation.

Brett Cannon3aa2a492008-08-06 22:28:09 +00002552- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
2553 the reload() built-in has been removed.
2554
Brett Cannon7e30b672008-08-04 21:52:25 +00002555- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00002556 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00002567 asking for a specific length. This problem only affected files opened

2624-----------------
2625
Georg Brandl3e483f62008-07-16 22:57:41 +00002626- Issue #3156: Fix inconsistent behavior of the bytearray type: all
2627 its methods now allow for items objects that can be converted to
2628 an integer using operator.index().
2629
Mark Dickinson64b7e502008-07-16 09:40:03 +00002630- Issue #3360: Fix incorrect parsing of '020000000000.0', which
2631 produced a ValueError instead of giving the correct float.
2632
Eric Smitha5fa5a22008-07-16 00:11:49 +00002633- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
2634 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
2635
Mark Dickinson7103aa42008-07-15 19:08:33 +00002636- Issue #3008: the float type has a new instance method 'float.hex'
2637 and a new class method 'float.fromhex' to convert floating-point
2638 numbers to and from hexadecimal strings, respectively.
2639
Nick Coghlan6d6bd442008-07-15 15:40:22 +00002640- Issue #2235: __hash__ is once again inherited by default. To allow
2641 collections.Hashable to remain meaningful in the presence of the
2642 default hash implementation (object.__hash__), it is now possible
2643 to explicit block inheritance of hash by setting __hash__=None at
2644 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
2645 level.
2646
Nick Coghlanb028f502008-07-13 14:52:36 +00002647- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
2648 the parent module cannot be found while performing an absolute import.
2649 This means that an incorrectly defined __package__ attribute will
2650 now only prevent relative imports in that module rather than causing
2651 all imports from that module to fail.
2652
Nick Coghlan14ff9942008-07-08 14:21:42 +00002653- Issue #2517: Allow unicode messages in Exceptions again by correctly

2663 another thread's dictionary.
2664
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00002665- Issue #3004: Minor change to slice.indices(): the start and stop
2666 arguments are now treated identically, making the behaviour easier
2667 to describe and understand. For example, slice(None, -10,
2668 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
2669 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
2670 10, -1).
2671
Georg Brandl278fc502008-07-19 12:46:12 +00002672- Issue #3219: Calling a function with repeated keyword arguments,
2673 f(a=2, a=23), would not cause a syntax error. This was a regression
2674 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002712- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
2713 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00002714 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00002715 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00002731- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl74a1dea2008-05-28 11:21:39 +00003142- Add ``PyType_Modified()`` as a public API to clear the type cache.
3143
3144- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00003145
3146- The PyString functions have been renamed to PyBytes. A batch of
3147 defines were added so that the linker still sees the original
3148 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003186- Issue #1631171: Re-implement the 'warnings' module in C (the
3187 original Python code has been kept as backup). This will allow for
3188 using the 'warning's machinery in such places as the parser where
3189 use of pure Python code is not possible. Both the ``showarning()``
3190 and ``formatwarning()`` gain an optional 'line' argument which is
3191 not called by default for backwards-compatibility reasons. Setting
3192 ``warnings.showwarning()`` to an implementation that lacks support
3193 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003218- The getpass module has been improved on Unix. It now uses /dev/tty
3219 by default and uses stderr instead of stdout. A GetPassWarning is
3220 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003235- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003236 extension modules between 32 and 64 bit platforms. See the distutls

3240 threads at once without fear of crashing the Python interpreter. If
3241 file.close() is called while an object is in use by another thread
3242 an IOError exception will be raised and the file will not be closed.
3243
Thomas Hellerf7906482008-04-04 19:43:25 +00003244- The bundled libffi copy is now in sync with the recently released

3249 so the controlled environment will more closely mirror the typical
3250 script environment. This supports setup.py scripts that refer to
3251 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003256- Issue #2550: The approach used by client/server code for obtaining
3257 ports to listen on in network-oriented tests has been refined in an
3258 effort to facilitate running multiple instances of the entire
3259 regression test suite in parallel without issue.
3260 test_support.bind_port() has been fixed such that it will always
3261 return a unique port -- which wasn't always the case with the
3262 previous implementation, especially if socket options had been set
3263 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3264 new implementation of bind_port() will actually raise an exception
3265 if it is passed an AF_INET/SOCK_STREAM socket with either the
3266 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3267 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3268 the socket it's been passed. This currently only applies to
3269 Windows. This option prevents any other sockets from binding to the
3270 host/port we've bound to, thus removing the possibility of the
3271 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3272 when a second SOCK_STREAM socket binds and accepts to a host/port
3273 that's already been bound by another socket. The optional preferred
3274 port parameter to bind_port() has been removed. Under no
3275 circumstances should tests be hard coding ports!
3276
3277 test_support.find_unused_port() has also been introduced, which will
3278 pass a temporary socket object to bind_port() in order to obtain an
3279 unused port. The temporary socket object is then closed and
3280 deleted, and the port is returned. This method should only be used
3281 for obtaining an unused port in order to pass to an external program
3282 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3283 a parameter to a server-oriented class that doesn't give you direct
3284 access to the underlying socket used.
3285
3286 Finally, test_support.HOST has been introduced, which should be used
3287 for the host argument of any relevant socket calls (i.e. bind and
3288 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003289
3290 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003291 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003292 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3293 test_asynchat and test_socket_ssl.
3294
Georg Brandl3ee81df2008-05-17 18:14:43 +00003295 It is now possible for multiple instances of the regression test
3296 suite to run in parallel without issue.

3563-----------------
3564
Fred Drakea8ee94b2008-03-01 02:45:07 +00003565- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003566 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00003572- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003573 issue 215555 for a discussion.
3574
Eric Smitha73fbe72008-02-23 03:09:44 +00003575- Added the future_builtins module, which contains hex() and oct().
3576 These are the PEP 3127 version of these functions, designed to be
3577 compatible with the hex() and oct() builtins from Python 3.0. They
3578 differ slightly in their output formats from the existing, unchanged
3579 Python 2.6 builtins. The expected usage of the future_builtins
3580 module is:
3581 from future_builtins import hex, oct
3582
Eric Smith7ef40bf2008-02-20 23:34:22 +00003583- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3584 exponents for exponents with absolute value < 100. Follows C99
3585 standard. This is a change on Windows, which would use 3 digits.
3586 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3587 so that any alterations it does to the resulting string will be
3588 available in stringlib/formatter.h (for float.__format__).
3589
Eric Smith5a3c1352008-02-19 13:21:56 +00003590- Implemented PEP 3101, Advanced String Formatting. This adds a new
3591 builtin format(); a format() method for str and unicode; a
3592 __format__() method to object, str, unicode, int, long, float, and
3593 datetime; the class string.Formatter; and the C API
3594 PyObject_Format().
3595
Georg Brandl3ee81df2008-05-17 18:14:43 +00003596- Fixed several potential crashes, all caused by specially crafted
3597 __del__ methods exploiting objects in temporarily inconsistent
3598 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003599
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003600- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003601 prevent a possible crash: an Abstract Base Class would try to access
3602 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003607- Clear all free lists during a gc.collect() of the highest generation
3608 in order to allow pymalloc to free more arenas. Python may give back
3609 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003610
Georg Brandl3ee81df2008-05-17 18:14:43 +00003611- Issue #2045: Fix an infinite recursion triggered when printing a
3612 subclass of collections.defaultdict, if its default_factory is set
3613 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003614
Christian Heimesf75dbef2008-02-08 00:11:31 +00003615- Fixed a minor memory leak in dictobject.c. The content of the free
3616 list was not freed on interpreter shutdown.
3617
Georg Brandl3ee81df2008-05-17 18:14:43 +00003618- Limit free list of method and builtin function objects to 256
3619 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003621- Patch #1953: Added ``sys._compact_freelists()`` and the C API
3622 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00003623 to compact the internal free lists of pre-allocted ints and floats.
3624
Georg Brandl3ee81df2008-05-17 18:14:43 +00003625- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
3626 calls. Python expected the return type int but the fork familie
3627 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00003628
Georg Brandl3ee81df2008-05-17 18:14:43 +00003629- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00003641- Patch #1473257: generator objects gain a gi_code attribute. This is
3642 the same object as the func_code attribute of the function that
3643 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00003644
Georg Brandl3ee81df2008-05-17 18:14:43 +00003645- Issue #1920: "while 0" statements were completely removed by the
3646 compiler, even in the presence of an "else" clause, which is
3647 supposed to be run when the condition is false. Now the compiler
3648 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00003649
Guido van Rossumeead05f2008-01-24 18:21:02 +00003650- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00003654- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00003655 suppressed while an extension is loaded by calling SetErrorMode in
3656 dynload_win.c. The error is still reported properly.
3657
Georg Brandl3ee81df2008-05-17 18:14:43 +00003658- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00003659 several extension methods and modules do not work without unicode
3660 support.
3661
Georg Brandl26543b12008-01-21 18:36:51 +00003662- Issue #1882: when compiling code from a string, encoding cookies in the
3663 second line of code were not always recognized correctly.
3664
Georg Brandl14404b62008-01-19 19:27:05 +00003665- Issue #1679: "0x" was taken as a valid integer literal.
3666
Georg Brandl6caad7d2008-01-26 14:19:22 +00003667- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00003668 added.
3669
Christian Heimesc94e2b52008-01-14 04:13:37 +00003670- sys.float_info / PyFloat_GetInfo: The floating point information
3671 object was converted from a dict to a specialized structseq object.
3672
Georg Brandl3ee81df2008-05-17 18:14:43 +00003673- Patch #1816: Added sys.flags structseq. It exposes the status of
3674 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00003675
Georg Brandl3ee81df2008-05-17 18:14:43 +00003676- Objects/structseq.c: Implemented new structseq representation. The
3677 patch makes structseqs (e.g. the return value of os.stat) more
3678 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00003679
Georg Brandl3ee81df2008-05-17 18:14:43 +00003680- Patch #1700288: added a type attribute cache that caches method
3681 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00003682
Neal Norwitz3fc15b82008-01-10 05:42:58 +00003683- Bug #1776: __import__() no longer accepts filenames on any platform.
3684 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00003685
Georg Brandlaed6c662008-01-07 17:25:53 +00003686- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
3687
Georg Brandl3ee81df2008-05-17 18:14:43 +00003688- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
3689 envvar and sys.dont_write_bytecode attribute. All these can be set
3690 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00003691
Georg Brandl3ee81df2008-05-17 18:14:43 +00003692- Improve some exception messages when Windows fails to load an
3693 extension module. Now we get for example '%1 is not a valid Win32
3694 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00003695
Georg Brandl3ee81df2008-05-17 18:14:43 +00003696- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003698- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
3699 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00003700
Christian Heimes0a8143f2007-12-18 23:22:54 +00003701- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00003702 and INF. float("nan"), float("inf") and float("-inf") now work on
3703 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00003704
Georg Brandl3ee81df2008-05-17 18:14:43 +00003705- Compiler now generates simpler and faster code for dictionary
3706 literals. The oparg for BUILD_MAP now indicates an estimated
3707 dictionary size. There is a new opcode, STORE_MAP, for adding
3708 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00003709
Georg Brandl3ee81df2008-05-17 18:14:43 +00003710- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003712- Issue #1620: New property decorator syntax was modifying the
3713 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00003714
Georg Brandl3ee81df2008-05-17 18:14:43 +00003715- Issue #1538: Avoid copying string in split/rsplit if the split char
3716 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00003717
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00003718- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00003719 SystemError.
3720
Nick Coghlanef01d822007-12-03 12:55:17 +00003721- PEP 366: Allow explicit relative imports when executing modules

3726 running, and if the deallocation of its frames somehow calls the
3727 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00003728

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00003732 attribute of an empty cell object.
3733
Georg Brandl3ee81df2008-05-17 18:14:43 +00003734- Issue #1460: The utf-7 incremental decoder did not accept truncated
3735 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00003736
Georg Brandl3ee81df2008-05-17 18:14:43 +00003737- Patch #1739468: Directories and zipfiles containing a __main__.py
3738 file can now be directly executed by passing their name to the
3739 interpreter. The directory/zipfile is automatically inserted as the
3740 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00003741
Georg Brandl3ee81df2008-05-17 18:14:43 +00003742- Issue #1265: Fix a problem with sys.settrace, if the tracing
3743 function uses a generator expression when at the same time the
3744 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00003745
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00003746- sets and frozensets now have an isdisjoint() method.
3747
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00003748- optimize the performance of builtin.sum().
3749
Neal Norwitz44f326e2007-10-05 05:29:17 +00003750- Fix warnings found by the new version of the Coverity checker.
3751
Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- The enumerate() builtin function is no longer bounded to sequences
3753 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
3754 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00003755
Georg Brandl3ee81df2008-05-17 18:14:43 +00003756- Issue #1686386: Tuple's tp_repr did not take into account the
3757 possibility of having a self-referential tuple, which is possible
3758 from C code. Nor did object's tp_str consider that a type's tp_str
3759 could do something that could lead to an inifinite recursion.
3760 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
3761 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00003762
Georg Brandl3ee81df2008-05-17 18:14:43 +00003763- Issue #1164: It was possible to trigger deadlock when using the
3764 'print' statement to write to a file since the GIL was not released
3765 as needed. Now PyObject_Print() does the right thing along with
3766 various tp_print implementations of the built-in types and those in
3767 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00003768
Georg Brandl3ee81df2008-05-17 18:14:43 +00003769- Issue #1147: Exceptions were directly allowing string exceptions in
3770 their throw() method even though string exceptions no longer
3771 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00003772
Georg Brandl3ee81df2008-05-17 18:14:43 +00003773- Issue #1096: Prevent a segfault from getting the repr of a very
3774 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00003775
Brett Cannon1e534b52007-09-07 04:18:30 +00003776- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00003777 PyObject_Call() never calling back out to Python code to trigger
3778 recursion depth updates/checks. Required the creation of a static
3779 RuntimeError instance in case normalizing an exception put the
3780 recursion check value past its limit. Fixes crashers
3781 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00003782
Georg Brandl3ee81df2008-05-17 18:14:43 +00003783- Patch #1031213: Decode source line in SyntaxErrors back to its
3784 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00003785
Georg Brandl7c3b50d2007-07-12 08:38:00 +00003786- Patch #1673759: add a missing overflow check when formatting floats
3787 with %G.
3788
Georg Brandl3ee81df2008-05-17 18:14:43 +00003789- Prevent expandtabs() on string and unicode objects from causing a
3790 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00003791

Georg Brandl3ee81df2008-05-17 18:14:43 +00003794- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00003795
Neal Norwitz0ac60192007-05-27 04:08:54 +00003796- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00003797 __*__ attributes. (Some already existed, e.g., __doc__ and
3798 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00003799
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00003800- Add -3 option to the interpreter to warn about features that are
3801 deprecated and will be changed/removed in Python 3.0.
3802
Georg Brandl2134e752007-05-21 20:34:16 +00003803- Patch #1686487: you can now pass any mapping after '**' in function
3804 calls.
3805
Collin Winter62903052007-05-18 23:11:24 +00003806- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00003807 "except E as target:". This is to provide forwards compatibility
3808 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00003809
Brett Cannon229cee22007-05-05 01:34:02 +00003810- Deprecate BaseException.message as per PEP 352.
3811
Georg Brandl3ee81df2008-05-17 18:14:43 +00003812- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00003813 inherited from a builtin base.
3814
Vinay Sajip8549ce32007-05-06 17:53:37 +00003815- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00003816 setting a plain string, ie don't expand to single letter identifiers.
3817
Raymond Hettinger13936692007-04-11 18:40:58 +00003818- Request #1191699: Slices can now be pickled.
3819
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00003820- Request #1193128: str.translate() now allows a None argument for
3821 translations that only remove characters without re-mapping the
3822 remaining characters.
3823
Georg Brandl5cb76c12007-03-21 09:00:39 +00003824- Patch #1682205: a TypeError while unpacking an iterable is no longer
3825 masked by a generic one with the message "unpack non-sequence".
3826
Neal Norwitzaa754b72007-03-21 06:39:48 +00003827- Remove unused file Python/fmod.c.
3828
Guido van Rossum143b5642007-03-23 04:58:42 +00003829- Bug #1683368: The object.__init__() and object.__new__() methods are
3830 now stricter in rejecting excess arguments. The only time when
3831 either allows excess arguments is when it is not overridden and the
3832 other one is. For backwards compatibility, when both are
3833 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00003834 warning later). Also, type.__init__() insists on the same signature
3835 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00003836
Georg Brandl3ee81df2008-05-17 18:14:43 +00003837- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
3838 object to complex using its __complex__() method before falling back
3839 to the __float__() method. Therefore, the functions in the cmath
3840 module now can operate on objects that define a __complex__()
3841 method.
Georg Brandl2b869942007-03-17 16:08:45 +00003842
Georg Brandl3ee81df2008-05-17 18:14:43 +00003843- Patch #1623563: allow __class__ assignment for classes with
3844 __slots__. The old and the new class are still required to have the
3845 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00003846
Georg Brandl3ee81df2008-05-17 18:14:43 +00003847- Patch #1642547: Fix an error/crash when encountering syntax errors
3848 in complex if statements.
Collin Winter77c67bd2007-03-16 04:11:30 +00003849
Georg Brandl3ee81df2008-05-17 18:14:43 +00003850- Patch #1462488: Python no longer segfaults when
3851 ``object.__reduce_ex__()`` is called with an object that is faking
3852 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00003853
Georg Brandl3ee81df2008-05-17 18:14:43 +00003854- Patch #1680015: Don't modify __slots__ tuple if it contains an
3855 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00003857- Patch #1444529: the builtin compile() now accepts keyword arguments.
3858
Georg Brandl7b9c5552007-03-12 14:30:05 +00003859- Bug #1678647: write a newline after printing an exception in any
3860 case, even when converting the value to a string failed.
3861
Georg Brandl871f1bc2007-03-12 13:17:36 +00003862- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00003863 its argument, if it exists. If not, it will work like before. This
3864 allows customizing the output of dir() in the presence of a
3865 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00003866
Collin Winter276887b2007-03-12 16:11:39 +00003867- Patch #922167: Python no longer segfaults when faced with infinitely
3868 self-recursive reload() calls (as reported by bug #742342).
3869
Georg Brandl3ee81df2008-05-17 18:14:43 +00003870- Patch #1675981: remove unreachable code from ``type.__new__()``
3871 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00003872
Georg Brandl3ee81df2008-05-17 18:14:43 +00003873- Patch #1491866: change the complex() constructor to allow
3874 parthensized forms. This means complex(repr(x)) now works instead of
3875 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00003876
Georg Brandlaa2321b2007-03-07 00:40:28 +00003877- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00003878 makes the filenames the warning module prints much more sensible
3879 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00003880
Georg Brandl49aafc92007-03-07 00:34:46 +00003881- Variant of patch #697613: don't exit the interpreter on a SystemExit
3882 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00003883 variable is given, but break into the interactive interpreter just
3884 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00003885
Georg Brandl3ee81df2008-05-17 18:14:43 +00003886- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00003889- Bug #1674503: close the file opened by execfile() in an error
3890 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00003891
Georg Brandl0fca97a2007-03-05 22:28:08 +00003892- Patch #1674228: when assigning a slice (old-style), check for the

4385 (as opposed to the command line) will now write file names ending in
4386 ".cpp" too.
4387
Facundo Batistad918a652007-04-24 13:54:38 +00004388- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004389 the client's request was successfully received, understood, and
4390 accepted. Now in these cases no error is raised in urllib (issue
4391 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00004392

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00004399- Added a timeout parameter to the constructor of other protocols
4400 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4401 work started with create_connection() and timeout in httplib, and
4402 closes patch #723312.
4403
Vinay Sajip8549ce32007-05-06 17:53:37 +00004404- Patch #1676823: Added create_connection() to socket.py, which may be
4405 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00004406 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00004407
Martin v. Löwis0af33882007-03-23 13:27:15 +00004408- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004415- Patch #1273829: os.walk() now has a "followlinks" parameter. If set

4420 GNOME or KDE browser, depending on whether there is a session of one
4421 of those present. Also, it tries the Windows default browser before
4422 trying Mozilla variants.

4427 initialization failed.
4428
Georg Brandlf66b6032007-03-14 08:27:52 +00004429- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00004430 AttributeError instead of an IOError when the server's response
4431 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00004432
Georg Brandl3ee81df2008-05-17 18:14:43 +00004433- Patch #957650: "%var%" environment variable references are now
4434 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00004436
Georg Brandl3ee81df2008-05-17 18:14:43 +00004437- Patch #1429539: pdb now correctly initializes the __main__ module
4438 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00004439 correctly now.
4440
Georg Brandlbad6f192007-03-13 21:32:56 +00004441- The nonobvious commands.getstatus() function is now deprecated.

4447
Georg Brandl3ee81df2008-05-17 18:14:43 +00004448- Patch #1530482: add pydoc.render_doc() which returns the
4449 documentation for a thing instead of paging it to stdout, which
4450 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00004451
Georg Brandl3ee81df2008-05-17 18:14:43 +00004452- Patch #1533909: the timeit module now accepts callables in addition

Georg Brandl3ee81df2008-05-17 18:14:43 +00004457- Patch #1537850: tempfile.NamedTemporaryFile now has a "delete"
4458 parameter which can be set to False to prevent the default
4459 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00004460
Georg Brandl9e6b4702007-03-13 18:15:41 +00004461- Patch #1581073: add a flag to textwrap that prevents the dropping of
4462 whitespace while wrapping.
4463
Georg Brandl92a6bae2007-03-13 17:43:32 +00004464- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004465 are set for invalid interpolation sequences that would lead to
4466 errors on reading back those values.

4506 Python would crash instead of raising an error.
4507

4509 returned string up to the first NUL character.
4510

4520
Georg Brandl3ee81df2008-05-17 18:14:43 +00004521- unittest now verifies more of its assumptions. In particular,
4522 TestCase and TestSuite subclasses (not instances) are no longer
4523 accepted in TestSuite.addTest(). This should cause no
4524 incompatibility since it never made sense with ordinary subclasses
4525 -- the failure just occurred later, with a more cumbersome
4526 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00004527

4535 given a unicode argument and os.listdir() returns unicode filenames.
4536
Georg Brandl3ee81df2008-05-17 18:14:43 +00004537- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00004915 time so that opening a database previously created with the DB_DUP
4916 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4917 opens. Specifically: dictionary assignment to a DB object will
4918 replace all values for a given key when the database allows
4919 duplicate values. DB users should use DB.put(k, v) when they want
4920 to store duplicates; not DB[k] = v.

4927 characters with ASCII value less than 32. Also, it correctly quotes
4928 dots only if they occur on a single line, as opposed to the previous
4929 behavior of quoting dots if they are the second character of any
4930 line.
