Ned Deily18fae3f2013-01-31 01:24:55 -08001033- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1034 In particular, fix extension module build failures when trying to use
1035 32-bit-only installer Pythons on systems with Xcode 4 (currently
1036 OS X 10.8, 10.7, and optionally 10.6).
1037 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1038 * Since Xcode 4 removes ppc support, extension module builds now
1039 check for ppc compiler support and by default remove ppc and
1040 ppc64 archs when they are not available.
1041 * Extension module builds now revert to using system installed
1042 headers and libs (/usr and /System/Library) if the SDK used
1043 to build the interpreter is not installed or has moved.
1044 * Try to avoid building extension modules with deprecated
1045 and problematic Apple llvm-gcc compiler. If original compiler
1046 is not available, use clang instead by default.

1480 64-bit/32-bit Pythons. If the user does not explicitly override
1481 the default C compiler by setting the CC environment variable,
1482 Distutils will now attempt to compile extension modules with clang

1487 SDK, neither of which are available in Xcode 4. This change does not
1488 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07001738- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
1739 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
1740 interpreter process. This could cause failures in non-Distutils subprocesses
1741 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02001742 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07001743 deployment target only in the environment of each build subprocess. It is
1744 still possible to globally override the default by setting
1745 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
1746 greater or equal to the default value, the value with which the interpreter
1747 was built.

1776 updating the check interval, so if the user decreases the check interval,
1777 the ticker doesn't have to wind down to zero from the old starting point
1778 before the new interval takes effect. And if the user increases the
1779 interval, it makes sure the new limit takes effect right away rather have an
1780 early task switch before recognizing the new interval.

Raymond Hettinger20397532010-09-12 02:11:45 +00002760- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
2761 This prevents user-created self-referencing ordered dictionaries from
2762 becoming permanently uncollectable GC garbage. The downside is that
2763 removing __del__ means that the internal doubly-linked list has to wait for
2764 GC collection rather than freeing memory immediately when the refcnt drops
2765 to zero.
2766
Raymond Hettingerffd2a422010-09-10 10:47:22 +00002767- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

2770
Antoine Pitrouc818ed42010-09-07 21:40:25 +00002771- Issue #9792: In case of connection failure, socket.create_connection()
2772 would swallow the exception and raise a new one, making it impossible
2773 to fetch the original errno, or to filter timeout errors. Now the
2774 original error is re-raised.
2775
Antoine Pitrouf4f61712010-09-07 16:34:47 +00002776- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

2795
R. David Murray7c4bf552010-08-25 01:45:57 +00002796- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
2797 character years even if the message contains RFC822 two character years.
2798
Daniel Stutzbach91287322010-08-24 21:09:30 +00002799- Issue #8750: Fixed MutableSet's methods to correctly handle

2812
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00002813- Issue #9617: Signals received during a low-level write operation aren't
2814 ignored by the buffered IO layer anymore.
2815
Benjamin Peterson52c36052010-08-21 03:03:22 +00002816- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

2818
Raymond Hettingera54b2da2010-08-17 19:03:06 +00002819- Issue #9626: the view methods for collections.OrderedDict() were returning
2820 the unordered versions inherited from dict. Those methods are now
2821 overridden to provide ordered views.

2825 without this marker will not be overwritten or removed.
2826
Antoine Pitroue1436d12010-08-12 15:25:51 +00002827- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
2828 and a BadZipfile error is raised if it doesn't match (as used to be the
2829 case in Python 2.5 and earlier).
2830
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00002831- Issue #9550: a BufferedReader could issue an additional read when the
2832 original read request had been satisfied, which could block indefinitely
2833 when the underlying raw IO channel was e.g. a socket. Report and original
2834 patch by Jason V. Miller.
2835
Fred Drake0a1fa0e2010-08-10 13:09:54 +00002836- Issue #9551: Don't raise TypeError when setting the value to None for

2855 This is how it is supposed to work, wget and curl do the same. Previous

3228 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
3229 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3230 Previous versions returned a single u'\ufffd'.

3240 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

Georg Brandlfee0f442010-05-22 21:26:21 +00003484- Issue #2302: Fix a race condition in SocketServer.BaseServer.shutdown, where
3485 the method could block indefinitely if called just before the event loop

Antoine Pitroufc69af12010-04-24 20:04:58 +00003489- Issue #5103: SSL handshake would ignore the socket timeout and block
3490 indefinitely if the other end didn't respond.
3491
Georg Brandlfee0f442010-05-22 21:26:21 +00003492- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00003585 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

Philip Jenveyaebbaeb2010-04-06 23:24:45 +00003610- Issue #7301: Add environment variable $PYTHONWARNINGS.
3611
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00003612- Issue #8329: Don't return the same lists from select.select when no fds are
3613 changed.
3614
Georg Brandlfee0f442010-05-22 21:26:21 +00003615- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00003616 on 64-bit machines. The shift count for either left or right shift is
3617 permitted to be up to sys.maxsize.
3618
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +00003619- Ensure that tokenization of identifiers is not affected by locale.

Georg Brandlfee0f442010-05-22 21:26:21 +00003625- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
3626 with a non-empty format string. This is an effort to future-proof user
3627 code. If a derived class does not currently implement __format__ but later
3628 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00003629 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00003630 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00003663- Issue #8257: The Decimal construct now accepts a float instance directly,
3664 converting that float to a Decimal of equal value:
Mark Dickinson8a950712010-04-03 15:47:46 +00003665

Georg Brandlfee0f442010-05-22 21:26:21 +00003680- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
3681 InvalidOperation instead of returning False. (Comparisons involving a quiet
3682 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
3683 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00003684
Georg Brandlfee0f442010-05-22 21:26:21 +00003685- Issue #2531: Comparison operations between floats and Decimal instances now
3686 return a result based on the numeric values of the operands; previously they
3687 returned an arbitrary result based on the relative ordering of id(float) and
3688 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00003702- Comparisons using one of <, <=, >, >= between a complex instance and a
3703 Fractions instance now raise TypeError instead of returning True/False. This
3704 makes Fraction <=> complex comparisons consistent with int <=> complex, float
3705 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004123 file position when calling `truncate()`. It would previously change the file
4124 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004125 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

4128 class used to represent files stored inside an archive. The new
4129 implementation is significantly faster and can be wrapped in a

4131 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4220-----------------
4221
Georg Brandlba83f822010-03-14 09:50:54 +00004222- The ``__complex__()`` method is now looked up on the class of instances to
4223 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004224
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004225- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
4226 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
4227
Mark Dickinson1b34d252010-01-01 17:27:30 +00004228- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004229 DeprecationWarning when passed a float argument where an integer was expected.
4230 These functions and methods now raise TypeError instead. The majority of the
4231 effects of this change are in the extension modules, but some core functions
4232 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4233 and many unicode/str methods.

4244 used to drop the time part of the result.
4245
Georg Brandlba83f822010-03-14 09:50:54 +00004246- Issue #1811: Improve accuracy and cross-platform consistency for true division
4247 of integers: the result of a/b is now correctly rounded for ints a and b (at
4248 least on IEEE 754 platforms), and in particular does not depend on the
4249 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00004250
Georg Brandlba83f822010-03-14 09:50:54 +00004251- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00004256 executables on OSX.
4257
Georg Brandlba83f822010-03-14 09:50:54 +00004258 These executables now work properly with the arch(1) command: ``arch -ppc
4259 python`` will start a universal binary version of python in PPC mode (unlike
4260 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00004283 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00004423- Issue #7117: On almost all platforms: float-to-string and string-to-float
4424 conversions within Python are now correctly rounded. Places these conversions
4425 occur include: str for floats and complex numbers; the float and complex
4426 constructors; old-style and new-style numeric formatting; serialization and
4427 deserialization of floats and complex numbers using marshal, pickle and json;
4428 parsing of float and imaginary literals in Python code; Decimal-to-float
4429 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004430
Georg Brandlba83f822010-03-14 09:50:54 +00004431 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4432 providing correctly-rounded strtod and dtoa C functions. This code is
4433 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4434 the C compiler. There may be a small number of platforms on which correct
4435 operation of this code cannot be guaranteed, so the code is not used: notably,
4436 this applies to platforms where the C double format is not IEEE 754 binary64,
4437 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4438 and Python's configure script is unable to determine how to change the FPU
4439 precision. On these platforms conversions use the platform strtod and dtoa,
4440 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004442- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4443 uses the correctly-rounded string <-> float conversions described above (when
4444 available), and so produces correctly rounded results that will display nicely
4445 under the float repr. There are two related small changes: (1) round now
4446 accepts any class with an ``__index__()`` method for its second argument (but
4447 no longer accepts floats for the second argument), and (2) an excessively
4448 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4449 raises an exception.

6034 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6035 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6036 neither __int__ nor __long__, TypeError used to be raised (with a
6037 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6038 struct.error in other cases.

6041 argument with an __int__ method can be packed, but use of this feature

6234
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006235- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
6236 PyString_FromFormat or PyErr_Format to display size_t values. The macro
6237 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6238 ``printf`` function, whereas PyString_FromFormat has an independent
6239 implementation and uses "%zd" on all platforms for size_t values.
6240 This makes a difference on win64, where ``printf`` needs "%Id" to display
6241 64bit values.

6264 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
6265 type object.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006336 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6337 for catch_warnings() also led to an improvement in the raising of a
6338 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006404What's New in Python 2.6 beta 3?
6405================================
6406
Barry Warsaw07a4a382008-08-21 01:15:08 +00006407*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006408
6409Core and Builtins
6410-----------------
6411
Guido van Rossumf8402962008-08-20 15:01:50 +00006412- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6413 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6414 extensions do not automatically benefit from the class attribute
6415 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6416 to their tp_flags field if they care. This is a backwards
6417 compatibility feature; in 3.0, all types will use the cache by
6418 default.
6419
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006420- Keyword arguments can now follow starred arguments. (``f(a, *args,
6421 keyword=23)`` is now valid syntax.)
6422
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006423- ctypes function pointers that are COM methods have a boolean True
6424 value again.
6425
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006426- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6427 by denying s# to parse objects that have a releasebuffer procedure,
6428 and introducing s*.
6429
Georg Brandl1e13ea92008-08-11 09:07:59 +00006430- Issue #3537: Fix an assertion failure when an empty but presized dict
6431 object was stored in the freelist.
6432
Mark Dickinsonb6467572008-08-04 21:30:09 +00006433- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6434 ValueError consistently across platforms.
6435
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006436- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6437 (64bit Unix, for example), unichr() would truncate its argument and return
6438 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6439
Neal Norwitze7d8be82008-07-31 17:17:14 +00006440- Apply security patches from Apple.
6441
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006442- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6443 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6444
Antoine Pitrou92f82162008-07-25 22:22:08 +00006445- Issue #1819: function calls with several named parameters are now on
6446 average 35% faster (as measured by pybench).
6447
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006448- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6449 the python debugger steps into a class statement: the free variables (local
6450 variables defined in an outer scope) would be deleted from the outer scope.
6451
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006452- Issue #2620: Overflow checking when allocating or reallocating memory
6453 was not always being done properly in some python types and extension
6454 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6455 all been updated to perform better checks and places in the code that
6456 would previously leak memory on the error path when such an allocation
6457 failed have been fixed.

6460-------
6461
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00006462- Issue #3612: Added some missing basic types in ctypes.wintypes.
6463
Benjamin Petersone977ad42008-08-20 01:42:01 +00006464- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
6465 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
6466
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00006467- Issue #2234: distutils failed for some versions of the cygwin compiler. The
6468 version reported by these tools does not necessarily follow the python
6469 version numbering scheme, so the module is less strict when parsing it.
6470
Nick Coghlanf70385a2008-08-18 12:42:46 +00006471- Issue #2235: Added Py3k warnings for types which will become unhashable
6472 under the stricter __hash__ inheritance rules in 3.0. Several types
6473 which did not meet the rules for hash invariants and were already
6474 unhashable in 3.0 have now been explicitly flagged as unhashable in
6475 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
6476 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
6477
Brett Cannon88f801d2008-08-18 00:46:22 +00006478- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
6479 imported into the module but exposed as part of the module's API.
6480
Brett Cannon7b96f072008-08-18 00:41:11 +00006481- Remove an unneeded import of abc.ABCMeta from 'inspect'.
6482
Brett Cannon46225e72008-08-18 00:36:52 +00006483- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00006485- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
6486
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00006487- Issue #3575: Incremental decoder's decode function now takes bytearray
6488 by using 's*' instead of 't#'.
6489
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00006490- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00006491 fails unicode conversion on 2nd parameter. (windows only)
6492
Georg Brandl222e2082010-08-01 22:27:39 +00006493- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00006494 in a redirect.
6495
Brett Cannonabe423e2008-08-16 21:47:07 +00006496- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00006497 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00006498
Facundo Batistaeb90b782008-08-16 14:44:07 +00006499- Issue #2776: fixed small issue when handling an URL with double slash
6500 after a 302 response in the case of not going through a proxy.
6501
Antoine Pitroub90a8be2008-08-15 21:03:21 +00006502- Issue #2676: in the email package, content-type parsing was hanging on
6503 pathological input because of quadratic or exponential behaviour of a
6504 regular expression.
6505
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00006506- Issue #3476: binary buffered reading through the new "io" library is now
6507 thread-safe.
6508
Brett Cannonbf3157b2008-08-14 05:00:03 +00006509- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
6510 since mimetools itself is deprecated. Because modules are cached, all
6511 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
6512
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00006513- Issue #3134: shutil referenced undefined WindowsError symbol.
6514
Robert Schuppenies14646332008-08-10 11:01:53 +00006515- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
6516 menu entries were not deleted.
6517
Brett Cannon83e81842008-08-09 23:30:55 +00006518- Copied the implementation of reduce() to _functools.reduce() to have a
6519 version that did not raise a DeprecationWarning under -3.
6520
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00006521- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
6522 a MemoryError rather than silently stop the iteration.
6523
Guido van Rossum59ce9012008-08-09 14:55:34 +00006524- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
6525 to _sre.compile() will now be rejected. This should not affect anybody
6526 since the re.compile() function never generates invalid re-bytecode.
6527
Skip Montanaroa032bf42008-08-08 22:52:51 +00006528- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
6529 upon first access it can be automatically initialized from the csv file if
6530 it wasn't initialized during instantiation.
6531
Brett Cannon3aa2a492008-08-06 22:28:09 +00006532- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
6533 the reload() built-in has been removed.
6534
Brett Cannon7e30b672008-08-04 21:52:25 +00006535- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00006536 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00006547 asking for a specific length. This problem only affected files opened
6548 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00006549

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006598What's New in Python 2.6 beta 2?
6599================================
6600
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006601*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00006603Core and Builtins
6604-----------------
6605
Georg Brandl3e483f62008-07-16 22:57:41 +00006606- Issue #3156: Fix inconsistent behavior of the bytearray type: all
6607 its methods now allow for items objects that can be converted to
6608 an integer using operator.index().
6609
Mark Dickinson64b7e502008-07-16 09:40:03 +00006610- Issue #3360: Fix incorrect parsing of '020000000000.0', which
6611 produced a ValueError instead of giving the correct float.
6612
Eric Smitha5fa5a22008-07-16 00:11:49 +00006613- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
6614 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
6615
Mark Dickinson7103aa42008-07-15 19:08:33 +00006616- Issue #3008: the float type has a new instance method 'float.hex'
6617 and a new class method 'float.fromhex' to convert floating-point
6618 numbers to and from hexadecimal strings, respectively.
6619
Nick Coghlan6d6bd442008-07-15 15:40:22 +00006620- Issue #2235: __hash__ is once again inherited by default. To allow
6621 collections.Hashable to remain meaningful in the presence of the
6622 default hash implementation (object.__hash__), it is now possible
6623 to explicit block inheritance of hash by setting __hash__=None at
6624 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
6625 level.
6626
Nick Coghlanb028f502008-07-13 14:52:36 +00006627- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
6628 the parent module cannot be found while performing an absolute import.
6629 This means that an incorrectly defined __package__ attribute will
6630 now only prevent relative imports in that module rather than causing
6631 all imports from that module to fail.
6632
Nick Coghlan14ff9942008-07-08 14:21:42 +00006633- Issue #2517: Allow unicode messages in Exceptions again by correctly
6634 bypassing the instance dictionary when looking up __unicode__ on
6635 new-style classes.
6636
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00006637- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
6638 set to a custom object whose write() method happens to install
6639 another file in sys.stdout.
6640
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00006641- Issue #3088: Corrected a race condition in classes derived from
6642 threading.local: the first member set by a thread could be saved in
6643 another thread's dictionary.
6644
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00006645- Issue #3004: Minor change to slice.indices(): the start and stop
6646 arguments are now treated identically, making the behaviour easier
6647 to describe and understand. For example, slice(None, -10,
6648 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
6649 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
6650 10, -1).
6651
Georg Brandl278fc502008-07-19 12:46:12 +00006652- Issue #3219: Calling a function with repeated keyword arguments,
6653 f(a=2, a=23), would not cause a syntax error. This was a regression
6654 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00006655
Georg Brandl278fc502008-07-19 12:46:12 +00006656- Issue #2862: Make int and float freelist management consistent with
6657 other freelists. Changes their CompactFreeList apis into
6658 ClearFreeList apis and calls them via gc.collect().

6664 api functions without holding the GIL, which could lead to a fatal
6665 error when they failed.
6666
Martin v. Löwisaabf4042008-08-02 07:20:25 +00006667- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

6676 ForkingPickler.register() to resolve conflict with ctypes.
6677
Vinay Sajip51e65192008-07-18 09:01:10 +00006678- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +00006679
Thomas Heller880f5292008-07-15 19:39:38 +00006680- Issue #3313: Fixed a crash when a failed dlopen() call does not set

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00006691
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006692- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
6693 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00006694 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00006695 content-length. The problem had been corrected in the 2.4 branch, but never
6696 merged into trunk.
6697
Georg Brandle78fbcc2008-07-05 10:13:36 +00006698- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00006711- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
6712 handling is now the same as that of other special attributes like __name__).
6713
Brett Cannon8bb8fa52008-07-02 01:57:08 +00006714- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

7171 not called by default for backwards-compatibility reasons. Setting
7172 ``warnings.showwarning()`` to an implementation that lacks support
7173 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007236- Issue #2550: The approach used by client/server code for obtaining
7237 ports to listen on in network-oriented tests has been refined in an
7238 effort to facilitate running multiple instances of the entire
7239 regression test suite in parallel without issue.
7240 test_support.bind_port() has been fixed such that it will always
7241 return a unique port -- which wasn't always the case with the
7242 previous implementation, especially if socket options had been set
7243 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7244 new implementation of bind_port() will actually raise an exception
7245 if it is passed an AF_INET/SOCK_STREAM socket with either the
7246 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7247 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7248 the socket it's been passed. This currently only applies to
7249 Windows. This option prevents any other sockets from binding to the
7250 host/port we've bound to, thus removing the possibility of the
7251 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7252 when a second SOCK_STREAM socket binds and accepts to a host/port
7253 that's already been bound by another socket. The optional preferred
7254 port parameter to bind_port() has been removed. Under no
7255 circumstances should tests be hard coding ports!
7256
7257 test_support.find_unused_port() has also been introduced, which will
7258 pass a temporary socket object to bind_port() in order to obtain an
7259 unused port. The temporary socket object is then closed and
7260 deleted, and the port is returned. This method should only be used
7261 for obtaining an unused port in order to pass to an external program
7262 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7263 a parameter to a server-oriented class that doesn't give you direct
7264 access to the underlying socket used.
7265
7266 Finally, test_support.HOST has been introduced, which should be used
7267 for the host argument of any relevant socket calls (i.e. bind and
7268 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007269
7270 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007271 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007272 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7273 test_asynchat and test_socket_ssl.
7274
Georg Brandl3ee81df2008-05-17 18:14:43 +00007275 It is now possible for multiple instances of the regression test
7276 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00007555- Added the future_builtins module, which contains hex() and oct().
7556 These are the PEP 3127 version of these functions, designed to be
7557 compatible with the hex() and oct() builtins from Python 3.0. They
7558 differ slightly in their output formats from the existing, unchanged
7559 Python 2.6 builtins. The expected usage of the future_builtins
7560 module is:
7561 from future_builtins import hex, oct
7562
Eric Smith7ef40bf2008-02-20 23:34:22 +00007563- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
7564 exponents for exponents with absolute value < 100. Follows C99
7565 standard. This is a change on Windows, which would use 3 digits.
7566 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
7567 so that any alterations it does to the resulting string will be
7568 available in stringlib/formatter.h (for float.__format__).
7569
Eric Smith5a3c1352008-02-19 13:21:56 +00007570- Implemented PEP 3101, Advanced String Formatting. This adds a new
7571 builtin format(); a format() method for str and unicode; a
7572 __format__() method to object, str, unicode, int, long, float, and
7573 datetime; the class string.Formatter; and the C API
7574 PyObject_Format().
7575
Georg Brandl3ee81df2008-05-17 18:14:43 +00007576- Fixed several potential crashes, all caused by specially crafted
7577 __del__ methods exploiting objects in temporarily inconsistent
7578 state.

7589 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00007590
Georg Brandl3ee81df2008-05-17 18:14:43 +00007591- Issue #2045: Fix an infinite recursion triggered when printing a
7592 subclass of collections.defaultdict, if its default_factory is set
7593 to a bound method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007621- Patch #1473257: generator objects gain a gi_code attribute. This is
7622 the same object as the func_code attribute of the function that
7623 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00007624
Georg Brandl3ee81df2008-05-17 18:14:43 +00007625- Issue #1920: "while 0" statements were completely removed by the
7626 compiler, even in the presence of an "else" clause, which is
7627 supposed to be run when the condition is false. Now the compiler
7628 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00007629

7652
Georg Brandl3ee81df2008-05-17 18:14:43 +00007653- Patch #1816: Added sys.flags structseq. It exposes the status of
7654 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00007655
Georg Brandl3ee81df2008-05-17 18:14:43 +00007656- Objects/structseq.c: Implemented new structseq representation. The
7657 patch makes structseqs (e.g. the return value of os.stat) more
7658 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00007659
Georg Brandl3ee81df2008-05-17 18:14:43 +00007660- Patch #1700288: added a type attribute cache that caches method
7661 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00007662
Neal Norwitz3fc15b82008-01-10 05:42:58 +00007663- Bug #1776: __import__() no longer accepts filenames on any platform.
7664 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00007665
Georg Brandlaed6c662008-01-07 17:25:53 +00007666- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
7667
Georg Brandl3ee81df2008-05-17 18:14:43 +00007668- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
7669 envvar and sys.dont_write_bytecode attribute. All these can be set
7670 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00007671
Georg Brandl3ee81df2008-05-17 18:14:43 +00007672- Improve some exception messages when Windows fails to load an
7673 extension module. Now we get for example '%1 is not a valid Win32
7674 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00007675
Georg Brandl3ee81df2008-05-17 18:14:43 +00007676- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007678- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
7679 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00007680
Christian Heimes0a8143f2007-12-18 23:22:54 +00007681- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00007682 and INF. float("nan"), float("inf") and float("-inf") now work on
7683 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00007684
Georg Brandl3ee81df2008-05-17 18:14:43 +00007685- Compiler now generates simpler and faster code for dictionary
7686 literals. The oparg for BUILD_MAP now indicates an estimated
7687 dictionary size. There is a new opcode, STORE_MAP, for adding
7688 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00007689
Georg Brandl3ee81df2008-05-17 18:14:43 +00007690- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007692- Issue #1620: New property decorator syntax was modifying the
7693 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00007694
Georg Brandl3ee81df2008-05-17 18:14:43 +00007695- Issue #1538: Avoid copying string in split/rsplit if the split char
7696 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00007697
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00007698- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00007699 SystemError.
7700
Nick Coghlanef01d822007-12-03 12:55:17 +00007701- PEP 366: Allow explicit relative imports when executing modules
7702 inside packages with the -m switch via a new module level
7703 __package__ attribute.
7704

7706 running, and if the deallocation of its frames somehow calls the
7707 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00007708

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00007712 attribute of an empty cell object.
7713
Georg Brandl3ee81df2008-05-17 18:14:43 +00007714- Issue #1460: The utf-7 incremental decoder did not accept truncated
7715 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00007716
Georg Brandl3ee81df2008-05-17 18:14:43 +00007717- Patch #1739468: Directories and zipfiles containing a __main__.py
7718 file can now be directly executed by passing their name to the
7719 interpreter. The directory/zipfile is automatically inserted as the
7720 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00007721
Georg Brandl3ee81df2008-05-17 18:14:43 +00007722- Issue #1265: Fix a problem with sys.settrace, if the tracing
7723 function uses a generator expression when at the same time the
7724 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00007725
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00007726- sets and frozensets now have an isdisjoint() method.
7727
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00007728- optimize the performance of builtin.sum().
7729
Neal Norwitz44f326e2007-10-05 05:29:17 +00007730- Fix warnings found by the new version of the Coverity checker.
7731
Georg Brandl21e99f42010-03-07 15:23:59 +00007732- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00007733 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
7734 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00007735
Georg Brandl3ee81df2008-05-17 18:14:43 +00007736- Issue #1686386: Tuple's tp_repr did not take into account the
7737 possibility of having a self-referential tuple, which is possible
7738 from C code. Nor did object's tp_str consider that a type's tp_str
7739 could do something that could lead to an inifinite recursion.
7740 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
7741 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00007742
Georg Brandl3ee81df2008-05-17 18:14:43 +00007743- Issue #1164: It was possible to trigger deadlock when using the
7744 'print' statement to write to a file since the GIL was not released
7745 as needed. Now PyObject_Print() does the right thing along with
7746 various tp_print implementations of the built-in types and those in
7747 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00007748
Georg Brandl3ee81df2008-05-17 18:14:43 +00007749- Issue #1147: Exceptions were directly allowing string exceptions in
7750 their throw() method even though string exceptions no longer
7751 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00007752
Georg Brandl3ee81df2008-05-17 18:14:43 +00007753- Issue #1096: Prevent a segfault from getting the repr of a very
7754 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00007755
Brett Cannon1e534b52007-09-07 04:18:30 +00007756- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00007757 PyObject_Call() never calling back out to Python code to trigger
7758 recursion depth updates/checks. Required the creation of a static
7759 RuntimeError instance in case normalizing an exception put the
7760 recursion check value past its limit. Fixes crashers
7761 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00007762
Georg Brandl3ee81df2008-05-17 18:14:43 +00007763- Patch #1031213: Decode source line in SyntaxErrors back to its

7767 with %G.
7768
Georg Brandl3ee81df2008-05-17 18:14:43 +00007769- Prevent expandtabs() on string and unicode objects from causing a
7770 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00007771

Neal Norwitz0ac60192007-05-27 04:08:54 +00007776- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00007777 __*__ attributes. (Some already existed, e.g., __doc__ and
7778 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00007779
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00007780- Add -3 option to the interpreter to warn about features that are
7781 deprecated and will be changed/removed in Python 3.0.
7782
Georg Brandl2134e752007-05-21 20:34:16 +00007783- Patch #1686487: you can now pass any mapping after '**' in function
7784 calls.
7785
Collin Winter62903052007-05-18 23:11:24 +00007786- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00007787 "except E as target:". This is to provide forwards compatibility
7788 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00007789
Brett Cannon229cee22007-05-05 01:34:02 +00007790- Deprecate BaseException.message as per PEP 352.
7791
Georg Brandl3ee81df2008-05-17 18:14:43 +00007792- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00007793 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00007794
Vinay Sajip8549ce32007-05-06 17:53:37 +00007795- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00007796 setting a plain string, ie don't expand to single letter identifiers.
7797
Raymond Hettinger13936692007-04-11 18:40:58 +00007798- Request #1191699: Slices can now be pickled.
7799
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00007800- Request #1193128: str.translate() now allows a None argument for
7801 translations that only remove characters without re-mapping the
7802 remaining characters.
7803
Georg Brandl5cb76c12007-03-21 09:00:39 +00007804- Patch #1682205: a TypeError while unpacking an iterable is no longer
7805 masked by a generic one with the message "unpack non-sequence".
7806
Neal Norwitzaa754b72007-03-21 06:39:48 +00007807- Remove unused file Python/fmod.c.
7808
Guido van Rossum143b5642007-03-23 04:58:42 +00007809- Bug #1683368: The object.__init__() and object.__new__() methods are
7810 now stricter in rejecting excess arguments. The only time when
7811 either allows excess arguments is when it is not overridden and the
7812 other one is. For backwards compatibility, when both are
7813 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00007814 warning later). Also, type.__init__() insists on the same signature
7815 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00007816
Georg Brandl3ee81df2008-05-17 18:14:43 +00007817- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
7818 object to complex using its __complex__() method before falling back
7819 to the __float__() method. Therefore, the functions in the cmath
7820 module now can operate on objects that define a __complex__()
7821 method.
Georg Brandl2b869942007-03-17 16:08:45 +00007822
Georg Brandl3ee81df2008-05-17 18:14:43 +00007823- Patch #1623563: allow __class__ assignment for classes with
7824 __slots__. The old and the new class are still required to have the
7825 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00007826
Georg Brandl3ee81df2008-05-17 18:14:43 +00007827- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00007830- Patch #1462488: Python no longer segfaults when
7831 ``object.__reduce_ex__()`` is called with an object that is faking
7832 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00007833
Georg Brandl3ee81df2008-05-17 18:14:43 +00007834- Patch #1680015: Don't modify __slots__ tuple if it contains an

7838
Georg Brandl7b9c5552007-03-12 14:30:05 +00007839- Bug #1678647: write a newline after printing an exception in any
7840 case, even when converting the value to a string failed.
7841
Georg Brandl871f1bc2007-03-12 13:17:36 +00007842- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00007843 its argument, if it exists. If not, it will work like before. This
7844 allows customizing the output of dir() in the presence of a
7845 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00007846
Collin Winter276887b2007-03-12 16:11:39 +00007847- Patch #922167: Python no longer segfaults when faced with infinitely
7848 self-recursive reload() calls (as reported by bug #742342).
7849
Georg Brandl3ee81df2008-05-17 18:14:43 +00007850- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00007853- Patch #1491866: change the complex() constructor to allow
7854 parthensized forms. This means complex(repr(x)) now works instead of
7855 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00007856
Georg Brandlaa2321b2007-03-07 00:40:28 +00007857- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00007858 makes the filenames the warning module prints much more sensible
7859 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00007860
Georg Brandl49aafc92007-03-07 00:34:46 +00007861- Variant of patch #697613: don't exit the interpreter on a SystemExit
7862 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00007863 variable is given, but break into the interactive interpreter just
7864 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00007871
Georg Brandl0fca97a2007-03-05 22:28:08 +00007872- Patch #1674228: when assigning a slice (old-style), check for the
7873 sq_ass_slice instead of the sq_slice slot.
7874
Georg Brandl3ee81df2008-05-17 18:14:43 +00007875- When printing an unraisable error, don't print exceptions. before
7876 the name. This duplicates the behavior whening normally printing
7877 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008379- Added a timeout parameter to the constructor of other protocols
8380 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8381 work started with create_connection() and timeout in httplib, and
8382 closes patch #723312.
8383
Vinay Sajip8549ce32007-05-06 17:53:37 +00008384- Patch #1676823: Added create_connection() to socket.py, which may be
8385 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00008386 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00008387

8408
Georg Brandlf66b6032007-03-14 08:27:52 +00008409- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00008410 AttributeError instead of an IOError when the server's response
8411 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008412
Georg Brandl3ee81df2008-05-17 18:14:43 +00008413- Patch #957650: "%var%" environment variable references are now
8414 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00008417- Patch #1429539: pdb now correctly initializes the __main__ module
8418 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008419 correctly now.
8420
Georg Brandlbad6f192007-03-13 21:32:56 +00008421- The nonobvious commands.getstatus() function is now deprecated.

8427
Georg Brandl3ee81df2008-05-17 18:14:43 +00008428- Patch #1530482: add pydoc.render_doc() which returns the
8429 documentation for a thing instead of paging it to stdout, which

8438 parameter which can be set to False to prevent the default
8439 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00008440
Georg Brandl9e6b4702007-03-13 18:15:41 +00008441- Patch #1581073: add a flag to textwrap that prevents the dropping of
8442 whitespace while wrapping.
8443
Georg Brandl92a6bae2007-03-13 17:43:32 +00008444- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008445 are set for invalid interpolation sequences that would lead to
8446 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00008447

Georg Brandl3ee81df2008-05-17 18:14:43 +00008462 field names in its exception message if you try to write a record
8463 with a dictionary containing fields not in the CSV field names list.

8487

8489 returned string up to the first NUL character.
8490

8500
Georg Brandl3ee81df2008-05-17 18:14:43 +00008501- unittest now verifies more of its assumptions. In particular,
8502 TestCase and TestSuite subclasses (not instances) are no longer
8503 accepted in TestSuite.addTest(). This should cause no
8504 incompatibility since it never made sense with ordinary subclasses
8505 -- the failure just occurred later, with a more cumbersome
8506 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00008507

8516
Georg Brandl3ee81df2008-05-17 18:14:43 +00008517- Patch #1673619: setup.py identifies extension modules it doesn't

8860 contents before adding elements from the iterable. This fix brings
8861 the behavior into line with that for list.__init__().

8871 complex, tuple, list, dict, set, and frozenset. Formerly, it would
8872 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008888- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00008889 time so that opening a database previously created with the DB_DUP
8890 or DB_DUPSORT flag set will keep the proper behavior on subsequent
8891 opens. Specifically: dictionary assignment to a DB object will
8892 replace all values for a given key when the database allows
8893 duplicate values. DB users should use DB.put(k, v) when they want
8894 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00008895

8901 characters with ASCII value less than 32. Also, it correctly quotes
8902 dots only if they occur on a single line, as opposed to the previous
8903 behavior of quoting dots if they are the second character of any
8904 line.
