Ned Deily18fae3f2013-01-31 01:24:55 -08001026- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1027 In particular, fix extension module build failures when trying to use
1028 32-bit-only installer Pythons on systems with Xcode 4 (currently
1029 OS X 10.8, 10.7, and optionally 10.6).
1030 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1031 * Since Xcode 4 removes ppc support, extension module builds now
1032 check for ppc compiler support and by default remove ppc and
1033 ppc64 archs when they are not available.
1034 * Extension module builds now revert to using system installed
1035 headers and libs (/usr and /System/Library) if the SDK used
1036 to build the interpreter is not installed or has moved.
1037 * Try to avoid building extension modules with deprecated
1038 and problematic Apple llvm-gcc compiler. If original compiler
1039 is not available, use clang instead by default.

1471 Distutils-based packages with C extension modules may fail because
1472 Apple has removed gcc-4.2, the version used to build python.org
1473 64-bit/32-bit Pythons. If the user does not explicitly override
1474 the default C compiler by setting the CC environment variable,
1475 Distutils will now attempt to compile extension modules with clang
1476 if gcc-4.2 is required but not found. Also as a convenience, if
1477 the user does explicitly set CC, substitute its value as the default
1478 compiler in the Distutils LDSHARED configuration variable for OS X.

Ned Deily87e82bb2011-06-28 19:52:59 -07001731- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1732 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1733 interpreter process. This could cause failures in non-Distutils subprocesses
1734 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001735 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001736 deployment target only in the environment of each build subprocess. It is
1737 still possible to globally override the default by setting
1738 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1739 greater or equal to the default value, the value with which the interpreter
1740 was built.

1770 the ticker doesn't have to wind down to zero from the old starting point
1771 before the new interval takes effect. And if the user increases the
1772 interval, it makes sure the new limit takes effect right away rather have an
1773 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002753- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2754 This prevents user-created self-referencing ordered dictionaries from
2755 becoming permanently uncollectable GC garbage. The downside is that
2756 removing __del__ means that the internal doubly-linked list has to wait for
2757 GC collection rather than freeing memory immediately when the refcnt drops
2758 to zero.
2759
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002760- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2763
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002764- Issue #9792: In case of connection failure, socket.create_connection()
2765 would swallow the exception and raise a new one, making it impossible
2766 to fetch the original errno, or to filter timeout errors. Now the
2767 original error is re-raised.
2768
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002769- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2788
R. David Murray7c4bf552010-08-25 01:45:57 +00002789- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2790 character years even if the message contains RFC822 two character years.
2791
Daniel Stutzbach91287322010-08-24 21:09:30 +00002792- Issue #8750: Fixed MutableSet's methods to correctly handle

2805
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002806- Issue #9617: Signals received during a low-level write operation aren't
2807 ignored by the buffered IO layer anymore.
2808
Benjamin Peterson52c36052010-08-21 03:03:22 +00002809- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2811
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002812- Issue #9626: the view methods for collections.OrderedDict() were returning
2813 the unordered versions inherited from dict. Those methods are now
2814 overridden to provide ordered views.

2817 comment indicating they are generated. Manually maintained MANIFESTs
2818 without this marker will not be overwritten or removed.
2819
Antoine Pitroue1436d12010-08-12 15:25:51 +00002820- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2821 and a BadZipfile error is raised if it doesn't match (as used to be the
2822 case in Python 2.5 and earlier).
2823
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002824- Issue #9550: a BufferedReader could issue an additional read when the
2825 original read request had been satisfied, which could block indefinitely
2826 when the underlying raw IO channel was e.g. a socket. Report and original
2827 patch by Jason V. Miller.
2828
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002829- Issue #9551: Don't raise TypeError when setting the value to None for

2848 This is how it is supposed to work, wget and curl do the same. Previous

3221 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3222 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3223 Previous versions returned a single u'\ufffd'.

3233 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00003477- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3478 the method could block indefinitely if called just before the event loop

Antoine Pitroufc69af12010-04-24 20:04:58 +00003482- Issue #5103: SSL handshake would ignore the socket timeout and block
3483 indefinitely if the other end didn't respond.
3484
Georg Brandlfee0f442010-05-22 21:26:21 +00003485- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003578 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003603- Issue #7301: Add environment variable $PYTHONWARNINGS.
3604
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003605- Issue #8329: Don't return the same lists from select.select when no fds are
3606 changed.
3607
Georg Brandlfee0f442010-05-22 21:26:21 +00003608- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003609 on 64-bit machines. The shift count for either left or right shift is
3610 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00003618- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3619 with a non-empty format string. This is an effort to future-proof user
3620 code. If a derived class does not currently implement __format__ but later
3621 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003622 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003623 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003656- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00003673- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3674 InvalidOperation instead of returning False. (Comparisons involving a quiet
3675 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3676 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003677
Georg Brandlfee0f442010-05-22 21:26:21 +00003678- Issue #2531: Comparison operations between floats and Decimal instances now
3679 return a result based on the numeric values of the operands; previously they
3680 returned an arbitrary result based on the relative ordering of id(float) and
3681 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003695- Comparisons using one of <, <=, >, >= between a complex instance and a
3696 Fractions instance now raise TypeError instead of returning True/False. This
3697 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3698 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004116 file position when calling `truncate()`. It would previously change the file
4117 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004118 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4121 class used to represent files stored inside an archive. The new
4122 implementation is significantly faster and can be wrapped in a

4124 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4213-----------------
4214
Georg Brandlba83f822010-03-14 09:50:54 +00004215- The ``__complex__()`` method is now looked up on the class of instances to
4216 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004217
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004218- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4219 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4220
Mark Dickinson1b34d252010-01-01 17:27:30 +00004221- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004222 DeprecationWarning when passed a float argument where an integer was expected.
4223 These functions and methods now raise TypeError instead. The majority of the
4224 effects of this change are in the extension modules, but some core functions
4225 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4226 and many unicode/str methods.

4237 used to drop the time part of the result.
4238
Georg Brandlba83f822010-03-14 09:50:54 +00004239- Issue #1811: Improve accuracy and cross-platform consistency for true division
4240 of integers: the result of a/b is now correctly rounded for ints a and b (at
4241 least on IEEE 754 platforms), and in particular does not depend on the
4242 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004243
Georg Brandlba83f822010-03-14 09:50:54 +00004244- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00004249 executables on OSX.
4250
Georg Brandlba83f822010-03-14 09:50:54 +00004251 These executables now work properly with the arch(1) command: ``arch -ppc
4252 python`` will start a universal binary version of python in PPC mode (unlike
4253 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004276 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00004416- Issue #7117: On almost all platforms: float-to-string and string-to-float
4417 conversions within Python are now correctly rounded. Places these conversions
4418 occur include: str for floats and complex numbers; the float and complex
4419 constructors; old-style and new-style numeric formatting; serialization and
4420 deserialization of floats and complex numbers using marshal, pickle and json;
4421 parsing of float and imaginary literals in Python code; Decimal-to-float
4422 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004423
Georg Brandlba83f822010-03-14 09:50:54 +00004424 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4425 providing correctly-rounded strtod and dtoa C functions. This code is
4426 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4427 the C compiler. There may be a small number of platforms on which correct
4428 operation of this code cannot be guaranteed, so the code is not used: notably,
4429 this applies to platforms where the C double format is not IEEE 754 binary64,
4430 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4431 and Python's configure script is unable to determine how to change the FPU
4432 precision. On these platforms conversions use the platform strtod and dtoa,
4433 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004435- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4436 uses the correctly-rounded string <-> float conversions described above (when
4437 available), and so produces correctly rounded results that will display nicely
4438 under the float repr. There are two related small changes: (1) round now
4439 accepts any class with an ``__index__()`` method for its second argument (but
4440 no longer accepts floats for the second argument), and (2) an excessively
4441 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4442 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00006022 - Packing a float now always gives a Deprecation Warning. Previously it

6027 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6028 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6029 neither __int__ nor __long__, TypeError used to be raised (with a
6030 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6031 struct.error in other cases.

6034 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006228- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6229 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6230 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6231 ``printf`` function, whereas PyString_FromFormat has an independent
6232 implementation and uses "%zd" on all platforms for size_t values.
6233 This makes a difference on win64, where ``printf`` needs "%Id" to display

Brett Cannon1eaf0742008-09-02 01:25:16 +00006329 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6330 for catch_warnings() also led to an improvement in the raising of a
6331 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006397What's New in Python 2.6 beta 3?
6398================================
6399
Barry Warsaw07a4a382008-08-21 01:15:08 +00006400*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006401
6402Core and Builtins
6403-----------------
6404
Guido van Rossumf8402962008-08-20 15:01:50 +00006405- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6406 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6407 extensions do not automatically benefit from the class attribute
6408 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6409 to their tp_flags field if they care. This is a backwards
6410 compatibility feature; in 3.0, all types will use the cache by
6411 default.
6412
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006413- Keyword arguments can now follow starred arguments. (``f(a, *args,
6414 keyword=23)`` is now valid syntax.)
6415
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006416- ctypes function pointers that are COM methods have a boolean True
6417 value again.
6418
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006419- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6420 by denying s# to parse objects that have a releasebuffer procedure,
6421 and introducing s*.
6422
Georg Brandl1e13ea92008-08-11 09:07:59 +00006423- Issue #3537: Fix an assertion failure when an empty but presized dict
6424 object was stored in the freelist.
6425
Mark Dickinsonb6467572008-08-04 21:30:09 +00006426- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6427 ValueError consistently across platforms.
6428
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006429- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6430 (64bit Unix, for example), unichr() would truncate its argument and return
6431 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6432
Neal Norwitze7d8be82008-07-31 17:17:14 +00006433- Apply security patches from Apple.
6434
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006435- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6436 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6437
Antoine Pitrou92f82162008-07-25 22:22:08 +00006438- Issue #1819: function calls with several named parameters are now on
6439 average 35% faster (as measured by pybench).
6440
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006441- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6442 the python debugger steps into a class statement: the free variables (local
6443 variables defined in an outer scope) would be deleted from the outer scope.
6444
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006445- Issue #2620: Overflow checking when allocating or reallocating memory
6446 was not always being done properly in some python types and extension
6447 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6448 all been updated to perform better checks and places in the code that
6449 would previously leak memory on the error path when such an allocation
6450 failed have been fixed.

6453-------
6454
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006455- Issue #3612: Added some missing basic types in ctypes.wintypes.
6456
Benjamin Petersone977ad42008-08-20 01:42:01 +00006457- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6458 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6459
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006460- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6461 version reported by these tools does not necessarily follow the python
6462 version numbering scheme, so the module is less strict when parsing it.
6463
Nick Coghlanf70385a2008-08-18 12:42:46 +00006464- Issue #2235: Added Py3k warnings for types which will become unhashable
6465 under the stricter __hash__ inheritance rules in 3.0. Several types
6466 which did not meet the rules for hash invariants and were already
6467 unhashable in 3.0 have now been explicitly flagged as unhashable in
6468 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6469 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6470
Brett Cannon88f801d2008-08-18 00:46:22 +00006471- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6472 imported into the module but exposed as part of the module's API.
6473
Brett Cannon7b96f072008-08-18 00:41:11 +00006474- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6475
Brett Cannon46225e72008-08-18 00:36:52 +00006476- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006478- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6479
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006480- Issue #3575: Incremental decoder's decode function now takes bytearray
6481 by using 's*' instead of 't#'.
6482
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006483- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006484 fails unicode conversion on 2nd parameter. (windows only)
6485
Georg Brandl222e2082010-08-01 22:27:39 +00006486- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006487 in a redirect.
6488
Brett Cannonabe423e2008-08-16 21:47:07 +00006489- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006490 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006491
Facundo Batistaeb90b782008-08-16 14:44:07 +00006492- Issue #2776: fixed small issue when handling an URL with double slash
6493 after a 302 response in the case of not going through a proxy.
6494
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006495- Issue #2676: in the email package, content-type parsing was hanging on
6496 pathological input because of quadratic or exponential behaviour of a
6497 regular expression.
6498
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006499- Issue #3476: binary buffered reading through the new "io" library is now
6500 thread-safe.
6501
Brett Cannonbf3157b2008-08-14 05:00:03 +00006502- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6503 since mimetools itself is deprecated. Because modules are cached, all
6504 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6505
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006506- Issue #3134: shutil referenced undefined WindowsError symbol.
6507
Robert Schuppenies14646332008-08-10 11:01:53 +00006508- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6509 menu entries were not deleted.
6510
Brett Cannon83e81842008-08-09 23:30:55 +00006511- Copied the implementation of reduce() to _functools.reduce() to have a
6512 version that did not raise a DeprecationWarning under -3.
6513
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006514- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6515 a MemoryError rather than silently stop the iteration.
6516
Guido van Rossum59ce9012008-08-09 14:55:34 +00006517- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6518 to _sre.compile() will now be rejected. This should not affect anybody
6519 since the re.compile() function never generates invalid re-bytecode.
6520
Skip Montanaroa032bf42008-08-08 22:52:51 +00006521- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6522 upon first access it can be automatically initialized from the csv file if
6523 it wasn't initialized during instantiation.
6524
Brett Cannon3aa2a492008-08-06 22:28:09 +00006525- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6526 the reload() built-in has been removed.
6527
Brett Cannon7e30b672008-08-04 21:52:25 +00006528- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006529 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006540 asking for a specific length. This problem only affected files opened
6541 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006542

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006591What's New in Python 2.6 beta 2?
6592================================
6593
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006594*Release date: 17-Jul-2008*
6595
Raymond Hettingere3ae6552008-06-20 04:18:15 +00006596Core and Builtins
6597-----------------
6598
Georg Brandl3e483f62008-07-16 22:57:41 +00006599- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6600 its methods now allow for items objects that can be converted to
6601 an integer using operator.index().
6602
Mark Dickinson64b7e502008-07-16 09:40:03 +00006603- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6604 produced a ValueError instead of giving the correct float.
6605
Eric Smitha5fa5a22008-07-16 00:11:49 +00006606- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6607 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6608
Mark Dickinson7103aa42008-07-15 19:08:33 +00006609- Issue #3008: the float type has a new instance method 'float.hex'
6610 and a new class method 'float.fromhex' to convert floating-point
6611 numbers to and from hexadecimal strings, respectively.
6612
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006613- Issue #2235: __hash__ is once again inherited by default. To allow
6614 collections.Hashable to remain meaningful in the presence of the
6615 default hash implementation (object.__hash__), it is now possible
6616 to explicit block inheritance of hash by setting __hash__=None at
6617 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6618 level.
6619
Nick Coghlanb028f502008-07-13 14:52:36 +00006620- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6621 the parent module cannot be found while performing an absolute import.
6622 This means that an incorrectly defined __package__ attribute will
6623 now only prevent relative imports in that module rather than causing
6624 all imports from that module to fail.
6625
Nick Coghlan14ff9942008-07-08 14:21:42 +00006626- Issue #2517: Allow unicode messages in Exceptions again by correctly
6627 bypassing the instance dictionary when looking up __unicode__ on
6628 new-style classes.
6629
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006630- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6631 set to a custom object whose write() method happens to install
6632 another file in sys.stdout.
6633
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006634- Issue #3088: Corrected a race condition in classes derived from
6635 threading.local: the first member set by a thread could be saved in
6636 another thread's dictionary.
6637
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006638- Issue #3004: Minor change to slice.indices(): the start and stop
6639 arguments are now treated identically, making the behaviour easier
6640 to describe and understand. For example, slice(None, -10,
6641 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6642 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6643 10, -1).
6644
Georg Brandl278fc502008-07-19 12:46:12 +00006645- Issue #3219: Calling a function with repeated keyword arguments,
6646 f(a=2, a=23), would not cause a syntax error. This was a regression
6647 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006648
Georg Brandl278fc502008-07-19 12:46:12 +00006649- Issue #2862: Make int and float freelist management consistent with
6650 other freelists. Changes their CompactFreeList apis into
6651 ClearFreeList apis and calls them via gc.collect().

6657 api functions without holding the GIL, which could lead to a fatal
6658 error when they failed.
6659
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006660- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6669 ForkingPickler.register() to resolve conflict with ctypes.
6670
Vinay Sajip51e65192008-07-18 09:01:10 +00006671- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006672

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006684
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006685- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6686 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006687 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006688 content-length. The problem had been corrected in the 2.4 branch, but never
6689 merged into trunk.
6690
Georg Brandle78fbcc2008-07-05 10:13:36 +00006691- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006704- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6705 handling is now the same as that of other special attributes like __name__).
6706
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006707- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7163 and ``formatwarning()`` gain an optional 'line' argument which is
7164 not called by default for backwards-compatibility reasons. Setting
7165 ``warnings.showwarning()`` to an implementation that lacks support
7166 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007229- Issue #2550: The approach used by client/server code for obtaining
7230 ports to listen on in network-oriented tests has been refined in an
7231 effort to facilitate running multiple instances of the entire
7232 regression test suite in parallel without issue.
7233 test_support.bind_port() has been fixed such that it will always
7234 return a unique port -- which wasn't always the case with the
7235 previous implementation, especially if socket options had been set
7236 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7237 new implementation of bind_port() will actually raise an exception
7238 if it is passed an AF_INET/SOCK_STREAM socket with either the
7239 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7240 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7241 the socket it's been passed. This currently only applies to
7242 Windows. This option prevents any other sockets from binding to the
7243 host/port we've bound to, thus removing the possibility of the
7244 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7245 when a second SOCK_STREAM socket binds and accepts to a host/port
7246 that's already been bound by another socket. The optional preferred
7247 port parameter to bind_port() has been removed. Under no
7248 circumstances should tests be hard coding ports!
7249
7250 test_support.find_unused_port() has also been introduced, which will
7251 pass a temporary socket object to bind_port() in order to obtain an
7252 unused port. The temporary socket object is then closed and
7253 deleted, and the port is returned. This method should only be used
7254 for obtaining an unused port in order to pass to an external program
7255 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7256 a parameter to a server-oriented class that doesn't give you direct
7257 access to the underlying socket used.
7258
7259 Finally, test_support.HOST has been introduced, which should be used
7260 for the host argument of any relevant socket calls (i.e. bind and
7261 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007262
7263 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007264 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007265 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7266 test_asynchat and test_socket_ssl.
7267
Georg Brandl3ee81df2008-05-17 18:14:43 +00007268 It is now possible for multiple instances of the regression test
7269 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007548- Added the future_builtins module, which contains hex() and oct().
7549 These are the PEP 3127 version of these functions, designed to be
7550 compatible with the hex() and oct() builtins from Python 3.0. They
7551 differ slightly in their output formats from the existing, unchanged
7552 Python 2.6 builtins. The expected usage of the future_builtins
7553 module is:
7554 from future_builtins import hex, oct
7555
Eric Smith7ef40bf2008-02-20 23:34:22 +00007556- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7557 exponents for exponents with absolute value < 100. Follows C99
7558 standard. This is a change on Windows, which would use 3 digits.
7559 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7560 so that any alterations it does to the resulting string will be
7561 available in stringlib/formatter.h (for float.__format__).
7562
Eric Smith5a3c1352008-02-19 13:21:56 +00007563- Implemented PEP 3101, Advanced String Formatting. This adds a new
7564 builtin format(); a format() method for str and unicode; a
7565 __format__() method to object, str, unicode, int, long, float, and
7566 datetime; the class string.Formatter; and the C API
7567 PyObject_Format().
7568
Georg Brandl3ee81df2008-05-17 18:14:43 +00007569- Fixed several potential crashes, all caused by specially crafted
7570 __del__ methods exploiting objects in temporarily inconsistent
7571 state.

7582 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007583
Georg Brandl3ee81df2008-05-17 18:14:43 +00007584- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00007614- Patch #1473257: generator objects gain a gi_code attribute. This is
7615 the same object as the func_code attribute of the function that
7616 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007617
Georg Brandl3ee81df2008-05-17 18:14:43 +00007618- Issue #1920: "while 0" statements were completely removed by the
7619 compiler, even in the presence of an "else" clause, which is
7620 supposed to be run when the condition is false. Now the compiler
7621 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007622

7645
Georg Brandl3ee81df2008-05-17 18:14:43 +00007646- Patch #1816: Added sys.flags structseq. It exposes the status of
7647 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007648
Georg Brandl3ee81df2008-05-17 18:14:43 +00007649- Objects/structseq.c: Implemented new structseq representation. The
7650 patch makes structseqs (e.g. the return value of os.stat) more
7651 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007652
Georg Brandl3ee81df2008-05-17 18:14:43 +00007653- Patch #1700288: added a type attribute cache that caches method
7654 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007655
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007656- Bug #1776: __import__() no longer accepts filenames on any platform.
7657 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007658
Georg Brandlaed6c662008-01-07 17:25:53 +00007659- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7660
Georg Brandl3ee81df2008-05-17 18:14:43 +00007661- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7662 envvar and sys.dont_write_bytecode attribute. All these can be set
7663 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007664
Georg Brandl3ee81df2008-05-17 18:14:43 +00007665- Improve some exception messages when Windows fails to load an
7666 extension module. Now we get for example '%1 is not a valid Win32
7667 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007668
Georg Brandl3ee81df2008-05-17 18:14:43 +00007669- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007671- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7672 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007673
Christian Heimes0a8143f2007-12-18 23:22:54 +00007674- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007675 and INF. float("nan"), float("inf") and float("-inf") now work on
7676 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007677
Georg Brandl3ee81df2008-05-17 18:14:43 +00007678- Compiler now generates simpler and faster code for dictionary
7679 literals. The oparg for BUILD_MAP now indicates an estimated
7680 dictionary size. There is a new opcode, STORE_MAP, for adding
7681 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007685- Issue #1620: New property decorator syntax was modifying the
7686 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007687
Georg Brandl3ee81df2008-05-17 18:14:43 +00007688- Issue #1538: Avoid copying string in split/rsplit if the split char
7689 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007690
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007691- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007692 SystemError.
7693
Nick Coghlanef01d822007-12-03 12:55:17 +00007694- PEP 366: Allow explicit relative imports when executing modules
7695 inside packages with the -m switch via a new module level
7696 __package__ attribute.

7699 running, and if the deallocation of its frames somehow calls the
7700 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007701

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007705 attribute of an empty cell object.
7706
Georg Brandl3ee81df2008-05-17 18:14:43 +00007707- Issue #1460: The utf-7 incremental decoder did not accept truncated
7708 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007709
Georg Brandl3ee81df2008-05-17 18:14:43 +00007710- Patch #1739468: Directories and zipfiles containing a __main__.py
7711 file can now be directly executed by passing their name to the
7712 interpreter. The directory/zipfile is automatically inserted as the
7713 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007714
Georg Brandl3ee81df2008-05-17 18:14:43 +00007715- Issue #1265: Fix a problem with sys.settrace, if the tracing
7716 function uses a generator expression when at the same time the
7717 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007718
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007719- sets and frozensets now have an isdisjoint() method.
7720
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007721- optimize the performance of builtin.sum().
7722
Neal Norwitz44f326e2007-10-05 05:29:17 +00007723- Fix warnings found by the new version of the Coverity checker.
7724
Georg Brandl21e99f42010-03-07 15:23:59 +00007725- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007726 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7727 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007728
Georg Brandl3ee81df2008-05-17 18:14:43 +00007729- Issue #1686386: Tuple's tp_repr did not take into account the
7730 possibility of having a self-referential tuple, which is possible
7731 from C code. Nor did object's tp_str consider that a type's tp_str
7732 could do something that could lead to an inifinite recursion.
7733 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7734 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007735
Georg Brandl3ee81df2008-05-17 18:14:43 +00007736- Issue #1164: It was possible to trigger deadlock when using the
7737 'print' statement to write to a file since the GIL was not released
7738 as needed. Now PyObject_Print() does the right thing along with
7739 various tp_print implementations of the built-in types and those in
7740 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007741
Georg Brandl3ee81df2008-05-17 18:14:43 +00007742- Issue #1147: Exceptions were directly allowing string exceptions in
7743 their throw() method even though string exceptions no longer
7744 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007745
Georg Brandl3ee81df2008-05-17 18:14:43 +00007746- Issue #1096: Prevent a segfault from getting the repr of a very
7747 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007748
Brett Cannon1e534b52007-09-07 04:18:30 +00007749- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007750 PyObject_Call() never calling back out to Python code to trigger
7751 recursion depth updates/checks. Required the creation of a static
7752 RuntimeError instance in case normalizing an exception put the
7753 recursion check value past its limit. Fixes crashers
7754 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007755
Georg Brandl3ee81df2008-05-17 18:14:43 +00007756- Patch #1031213: Decode source line in SyntaxErrors back to its

7760 with %G.
7761
Georg Brandl3ee81df2008-05-17 18:14:43 +00007762- Prevent expandtabs() on string and unicode objects from causing a
7763 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00007769- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007770 __*__ attributes. (Some already existed, e.g., __doc__ and
7771 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007772
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007773- Add -3 option to the interpreter to warn about features that are
7774 deprecated and will be changed/removed in Python 3.0.
7775
Georg Brandl2134e752007-05-21 20:34:16 +00007776- Patch #1686487: you can now pass any mapping after '**' in function
7777 calls.
7778
Collin Winter62903052007-05-18 23:11:24 +00007779- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007780 "except E as target:". This is to provide forwards compatibility
7781 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007782
Brett Cannon229cee22007-05-05 01:34:02 +00007783- Deprecate BaseException.message as per PEP 352.
7784
Georg Brandl3ee81df2008-05-17 18:14:43 +00007785- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007786 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007787
Vinay Sajip8549ce32007-05-06 17:53:37 +00007788- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007789 setting a plain string, ie don't expand to single letter identifiers.
7790
Raymond Hettinger13936692007-04-11 18:40:58 +00007791- Request #1191699: Slices can now be pickled.
7792
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007793- Request #1193128: str.translate() now allows a None argument for
7794 translations that only remove characters without re-mapping the
7795 remaining characters.
7796
Georg Brandl5cb76c12007-03-21 09:00:39 +00007797- Patch #1682205: a TypeError while unpacking an iterable is no longer
7798 masked by a generic one with the message "unpack non-sequence".
7799
Neal Norwitzaa754b72007-03-21 06:39:48 +00007800- Remove unused file Python/fmod.c.
7801
Guido van Rossum143b5642007-03-23 04:58:42 +00007802- Bug #1683368: The object.__init__() and object.__new__() methods are
7803 now stricter in rejecting excess arguments. The only time when
7804 either allows excess arguments is when it is not overridden and the
7805 other one is. For backwards compatibility, when both are
7806 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007807 warning later). Also, type.__init__() insists on the same signature
7808 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007809
Georg Brandl3ee81df2008-05-17 18:14:43 +00007810- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7811 object to complex using its __complex__() method before falling back
7812 to the __float__() method. Therefore, the functions in the cmath
7813 module now can operate on objects that define a __complex__()
7814 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007815
Georg Brandl3ee81df2008-05-17 18:14:43 +00007816- Patch #1623563: allow __class__ assignment for classes with
7817 __slots__. The old and the new class are still required to have the
7818 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007819
Georg Brandl3ee81df2008-05-17 18:14:43 +00007820- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00007823- Patch #1462488: Python no longer segfaults when
7824 ``object.__reduce_ex__()`` is called with an object that is faking
7825 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007826
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827- Patch #1680015: Don't modify __slots__ tuple if it contains an

7831
Georg Brandl7b9c5552007-03-12 14:30:05 +00007832- Bug #1678647: write a newline after printing an exception in any
7833 case, even when converting the value to a string failed.
7834
Georg Brandl871f1bc2007-03-12 13:17:36 +00007835- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007836 its argument, if it exists. If not, it will work like before. This
7837 allows customizing the output of dir() in the presence of a
7838 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007839
Collin Winter276887b2007-03-12 16:11:39 +00007840- Patch #922167: Python no longer segfaults when faced with infinitely
7841 self-recursive reload() calls (as reported by bug #742342).
7842
Georg Brandl3ee81df2008-05-17 18:14:43 +00007843- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007846- Patch #1491866: change the complex() constructor to allow
7847 parthensized forms. This means complex(repr(x)) now works instead of
7848 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007849
Georg Brandlaa2321b2007-03-07 00:40:28 +00007850- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007851 makes the filenames the warning module prints much more sensible
7852 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007853
Georg Brandl49aafc92007-03-07 00:34:46 +00007854- Variant of patch #697613: don't exit the interpreter on a SystemExit
7855 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007856 variable is given, but break into the interactive interpreter just
7857 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007864
Georg Brandl0fca97a2007-03-05 22:28:08 +00007865- Patch #1674228: when assigning a slice (old-style), check for the
7866 sq_ass_slice instead of the sq_slice slot.
7867
Georg Brandl3ee81df2008-05-17 18:14:43 +00007868- When printing an unraisable error, don't print exceptions. before
7869 the name. This duplicates the behavior whening normally printing
7870 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008372- Added a timeout parameter to the constructor of other protocols
8373 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8374 work started with create_connection() and timeout in httplib, and
8375 closes patch #723312.
8376
Vinay Sajip8549ce32007-05-06 17:53:37 +00008377- Patch #1676823: Added create_connection() to socket.py, which may be
8378 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008379 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008380

8401
Georg Brandlf66b6032007-03-14 08:27:52 +00008402- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008403 AttributeError instead of an IOError when the server's response
8404 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008405
Georg Brandl3ee81df2008-05-17 18:14:43 +00008406- Patch #957650: "%var%" environment variable references are now
8407 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00008410- Patch #1429539: pdb now correctly initializes the __main__ module
8411 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008412 correctly now.
8413
Georg Brandlbad6f192007-03-13 21:32:56 +00008414- The nonobvious commands.getstatus() function is now deprecated.

8420
Georg Brandl3ee81df2008-05-17 18:14:43 +00008421- Patch #1530482: add pydoc.render_doc() which returns the
8422 documentation for a thing instead of paging it to stdout, which

8431 parameter which can be set to False to prevent the default
8432 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008433
Georg Brandl9e6b4702007-03-13 18:15:41 +00008434- Patch #1581073: add a flag to textwrap that prevents the dropping of
8435 whitespace while wrapping.
8436
Georg Brandl92a6bae2007-03-13 17:43:32 +00008437- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008438 are set for invalid interpolation sequences that would lead to
8439 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008440

Georg Brandl3ee81df2008-05-17 18:14:43 +00008455 field names in its exception message if you try to write a record
8456 with a dictionary containing fields not in the CSV field names list.

8480

8482 returned string up to the first NUL character.

8493
Georg Brandl3ee81df2008-05-17 18:14:43 +00008494- unittest now verifies more of its assumptions. In particular,
8495 TestCase and TestSuite subclasses (not instances) are no longer
8496 accepted in TestSuite.addTest(). This should cause no
8497 incompatibility since it never made sense with ordinary subclasses
8498 -- the failure just occurred later, with a more cumbersome
8499 exception.

8509
Georg Brandl3ee81df2008-05-17 18:14:43 +00008510- Patch #1673619: setup.py identifies extension modules it doesn't

8853 contents before adding elements from the iterable. This fix brings
8854 the behavior into line with that for list.__init__().

8864 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8865 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008881- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008882 time so that opening a database previously created with the DB_DUP
8883 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8884 opens. Specifically: dictionary assignment to a DB object will
8885 replace all values for a given key when the database allows
8886 duplicate values. DB users should use DB.put(k, v) when they want
8887 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008888

8894 characters with ASCII value less than 32. Also, it correctly quotes
8895 dots only if they occur on a single line, as opposed to the previous
8896 behavior of quoting dots if they are the second character of any
8897 line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009284- Added case insensitive comparison methods ``PyOS_stricmp(char*,
9285 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
