40 longer include a "manifest" to prevent them failing at import time in some
41 embedded situations.

Mark Dickinsondbbed042011-09-19 16:38:08 +010052- Issue #12973: Fix overflow checks that invoked undefined behaviour in
53 int.__pow__. These overflow checks were causing int.__pow__ to produce
54 incorrect results with recent versions of Clang, as a result of the
Mark Dickinsona96b0d12011-09-24 09:01:16 +010055 compiler optimizing the check away. Also fix similar overflow checks
56 in list_repeat (listobject.c) and islice_next (itertoolsmodule.c). These
57 bugs caused test failures with recent versions of Clang.

69 cleared by the garbage collector. This fixes a segfault when an instance
70 and its type get caught in a reference cycle, and the instance's
71 deallocator calls one of the methods on the type (e.g. when subclassing
72 IOBase). Diagnosis and patch by Davide Rizzo.

82 raw_input() interrupted by CTRL+c.
83

Ned Deily87e82bb2011-06-28 19:52:59 -0700351- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
352 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
353 interpreter process. This could cause failures in non-Distutils subprocesses
354 and was unreliable since tests or user programs could modify the interpreter
355 environment after Distutils set it. Instead, have Distutils set the the
356 deployment target only in the environment of each build subprocess. It is
357 still possible to globally override the default by setting
358 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
359 greater or equal to the default value, the value with which the interpreter
360 was built.

1321 This prevents user-created self-referencing ordered dictionaries from
1322 becoming permanently uncollectable GC garbage. The downside is that
1323 removing __del__ means that the internal doubly-linked list has to wait for
1324 GC collection rather than freeing memory immediately when the refcnt drops
1325 to zero.

1783
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001784- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1785 start byte and the continuation byte(s) are now considered invalid, instead
1786 of the number of bytes specified by the start byte.
1787 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1788 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1789 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
1790 Previous versions returned a single u'\ufffd'.
1791
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001792- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00001793 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
1794 arises from the "Overriding __eq__ blocks inheritance ..." warning
1795 when turned into an exception: in this case the exception simply
1796 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00001797
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001798- Issue #8748: Fix two issues with comparisons between complex and integer
1799 objects. (1) The comparison could incorrectly return True in some cases
1800 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1801 (2) The comparison raised an OverflowError for large integers, leading
1802 to unpredictable exceptions when combining integers and complex objects
1803 in sets or dicts.
1804
Mark Dickinson81336372010-05-30 12:12:25 +00001805- Issue #5211: Implicit coercion for the complex type is now completely
1806 removed. (Coercion for arithmetic operations was already removed in 2.7
1807 alpha 4, but coercion for rich comparisons was accidentally left in.)
1808
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00001809- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
1810 and error handler, instead of writing to the C stderr file in utf-8
1811
Georg Brandlfee0f442010-05-22 21:26:21 +00001812- Issue #7902: When using explicit relative import syntax, don't try implicit
1813 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +00001814
Georg Brandlfee0f442010-05-22 21:26:21 +00001815- Issue #7079: Fix a possible crash when closing a file object while using it
1816 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +00001817
Victor Stinnerb65bd2e2010-06-11 19:22:28 +00001818- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +00001819 Window Server again in a framework build on MacOSX 10.5 or earlier.

Georg Brandlfee0f442010-05-22 21:26:21 +00001824- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
1825 of the interpreter to set sys.argv without also modifying sys.path. This
1826 helps fix `CVE-2008-5983

1943 non-float non-integer argument is now converted to an integer (if possible)
1944 using its __int__ method. Previously, only small arguments were treated this

2186 with a non-empty format string. This is an effort to future-proof user
2187 code. If a derived class does not currently implement __format__ but later
2188 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002189 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002190 Python 3.3 and it will be an error in Python 3.4.

2628 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2629 returning NULL. The macro now returns a statically allocated empty string
2630 instead.

2640 strings,
2641 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2642 numeric strings corresponding to subnormal values,
2643 (3) a memory leak for some values large enough to cause overflow, and
2644 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00002675- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002676 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002677 Also, raise ValueError rather than TypeError when an unknown TIPC address
2678 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002682- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002683 file position when calling `truncate()`. It would previously change the file
2684 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002685 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2686
Georg Brandlba83f822010-03-14 09:50:54 +00002687- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2688 class used to represent files stored inside an archive. The new
2689 implementation is significantly faster and can be wrapped in a
2690 ``io.BufferedReader`` object for more speedups. It also solves an issue
2691 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2692 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00002702- Issue #7748: Since unicode values are supported for some metadata options in
2703 Distutils, the DistributionMetadata get_* methods will now return an utf-8
2704 encoded string for them. This ensures that the upload and register commands
2705 send the correct values to PyPI without any error.

Mark Dickinson1b34d252010-01-01 17:27:30 +00002788- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002789 DeprecationWarning when passed a float argument where an integer was expected.
2790 These functions and methods now raise TypeError instead. The majority of the
2791 effects of this change are in the extension modules, but some core functions
2792 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
2793 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00002976- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2977 decimal string that's guaranteed to round back to x under correct rounding
2978 (with round-half-to-even rounding mode). Previously it gave a string based on
2979 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2980 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2981 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002983- Issue #7117: On almost all platforms: float-to-string and string-to-float
2984 conversions within Python are now correctly rounded. Places these conversions
2985 occur include: str for floats and complex numbers; the float and complex
2986 constructors; old-style and new-style numeric formatting; serialization and
2987 deserialization of floats and complex numbers using marshal, pickle and json;
2988 parsing of float and imaginary literals in Python code; Decimal-to-float
2989 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002990
Georg Brandlba83f822010-03-14 09:50:54 +00002991 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2992 providing correctly-rounded strtod and dtoa C functions. This code is
2993 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2994 the C compiler. There may be a small number of platforms on which correct
2995 operation of this code cannot be guaranteed, so the code is not used: notably,
2996 this applies to platforms where the C double format is not IEEE 754 binary64,
2997 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2998 and Python's configure script is unable to determine how to change the FPU
2999 precision. On these platforms conversions use the platform strtod and dtoa,
3000 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003002- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3003 uses the correctly-rounded string <-> float conversions described above (when
3004 available), and so produces correctly rounded results that will display nicely
3005 under the float repr. There are two related small changes: (1) round now
3006 accepts any class with an ``__index__()`` method for its second argument (but
3007 no longer accepts floats for the second argument), and (2) an excessively
3008 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3009 raises an exception.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004792- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

4794 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4795 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00004893 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4894 for catch_warnings() also led to an improvement in the raising of a
4895 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004961What's New in Python 2.6 beta 3?
4962================================
4963
Barry Warsaw07a4a382008-08-21 01:15:08 +00004964*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004965
4966Core and Builtins
4967-----------------
4968
Guido van Rossumf8402962008-08-20 15:01:50 +00004969- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4970 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4971 extensions do not automatically benefit from the class attribute
4972 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4973 to their tp_flags field if they care. This is a backwards
4974 compatibility feature; in 3.0, all types will use the cache by
4975 default.
4976
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004977- Keyword arguments can now follow starred arguments. (``f(a, *args,
4978 keyword=23)`` is now valid syntax.)
4979
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004980- ctypes function pointers that are COM methods have a boolean True
4981 value again.
4982
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004983- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4984 by denying s# to parse objects that have a releasebuffer procedure,
4985 and introducing s*.
4986
Georg Brandl1e13ea92008-08-11 09:07:59 +00004987- Issue #3537: Fix an assertion failure when an empty but presized dict
4988 object was stored in the freelist.
4989
Mark Dickinsonb6467572008-08-04 21:30:09 +00004990- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4991 ValueError consistently across platforms.
4992
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004993- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4994 (64bit Unix, for example), unichr() would truncate its argument and return
4995 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4996
Neal Norwitze7d8be82008-07-31 17:17:14 +00004997- Apply security patches from Apple.
4998
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004999- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5000 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5001
Antoine Pitrou92f82162008-07-25 22:22:08 +00005002- Issue #1819: function calls with several named parameters are now on
5003 average 35% faster (as measured by pybench).
5004
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005005- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5006 the python debugger steps into a class statement: the free variables (local
5007 variables defined in an outer scope) would be deleted from the outer scope.
5008
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005009- Issue #2620: Overflow checking when allocating or reallocating memory
5010 was not always being done properly in some python types and extension
5011 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5012 all been updated to perform better checks and places in the code that
5013 would previously leak memory on the error path when such an allocation
5014 failed have been fixed.

5017-------
5018
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005019- Issue #3612: Added some missing basic types in ctypes.wintypes.
5020
Benjamin Petersone977ad42008-08-20 01:42:01 +00005021- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5022 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5023
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005024- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5025 version reported by these tools does not necessarily follow the python
5026 version numbering scheme, so the module is less strict when parsing it.
5027
Nick Coghlanf70385a2008-08-18 12:42:46 +00005028- Issue #2235: Added Py3k warnings for types which will become unhashable
5029 under the stricter __hash__ inheritance rules in 3.0. Several types
5030 which did not meet the rules for hash invariants and were already
5031 unhashable in 3.0 have now been explicitly flagged as unhashable in
5032 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5033 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5034
Brett Cannon88f801d2008-08-18 00:46:22 +00005035- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5036 imported into the module but exposed as part of the module's API.
5037
Brett Cannon7b96f072008-08-18 00:41:11 +00005038- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5039
Brett Cannon46225e72008-08-18 00:36:52 +00005040- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005042- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5043
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005044- Issue #3575: Incremental decoder's decode function now takes bytearray
5045 by using 's*' instead of 't#'.
5046
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005047- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005048 fails unicode conversion on 2nd parameter. (windows only)
5049
Georg Brandl222e2082010-08-01 22:27:39 +00005050- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005051 in a redirect.
5052
Brett Cannonabe423e2008-08-16 21:47:07 +00005053- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005054 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005055
Facundo Batistaeb90b782008-08-16 14:44:07 +00005056- Issue #2776: fixed small issue when handling an URL with double slash
5057 after a 302 response in the case of not going through a proxy.
5058
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005059- Issue #2676: in the email package, content-type parsing was hanging on
5060 pathological input because of quadratic or exponential behaviour of a
5061 regular expression.
5062
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005063- Issue #3476: binary buffered reading through the new "io" library is now
5064 thread-safe.
5065
Brett Cannonbf3157b2008-08-14 05:00:03 +00005066- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5067 since mimetools itself is deprecated. Because modules are cached, all
5068 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5069
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005070- Issue #3134: shutil referenced undefined WindowsError symbol.
5071
Robert Schuppenies14646332008-08-10 11:01:53 +00005072- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5073 menu entries were not deleted.
5074
Brett Cannon83e81842008-08-09 23:30:55 +00005075- Copied the implementation of reduce() to _functools.reduce() to have a
5076 version that did not raise a DeprecationWarning under -3.
5077
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005078- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5079 a MemoryError rather than silently stop the iteration.
5080
Guido van Rossum59ce9012008-08-09 14:55:34 +00005081- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5082 to _sre.compile() will now be rejected. This should not affect anybody
5083 since the re.compile() function never generates invalid re-bytecode.
5084
Skip Montanaroa032bf42008-08-08 22:52:51 +00005085- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5086 upon first access it can be automatically initialized from the csv file if
5087 it wasn't initialized during instantiation.
5088
Brett Cannon3aa2a492008-08-06 22:28:09 +00005089- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5090 the reload() built-in has been removed.
5091
Brett Cannon7e30b672008-08-04 21:52:25 +00005092- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00005093 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

5096 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
5097 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
5098 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00005099

Antoine Pitroude781a42008-08-09 12:43:23 +00005104 asking for a specific length. This problem only affected files opened

5161-----------------
5162
Georg Brandl3e483f62008-07-16 22:57:41 +00005163- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5164 its methods now allow for items objects that can be converted to
5165 an integer using operator.index().
5166
Mark Dickinson64b7e502008-07-16 09:40:03 +00005167- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5168 produced a ValueError instead of giving the correct float.
5169
Eric Smitha5fa5a22008-07-16 00:11:49 +00005170- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5171 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5172
Mark Dickinson7103aa42008-07-15 19:08:33 +00005173- Issue #3008: the float type has a new instance method 'float.hex'
5174 and a new class method 'float.fromhex' to convert floating-point
5175 numbers to and from hexadecimal strings, respectively.
5176
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005177- Issue #2235: __hash__ is once again inherited by default. To allow
5178 collections.Hashable to remain meaningful in the presence of the
5179 default hash implementation (object.__hash__), it is now possible
5180 to explicit block inheritance of hash by setting __hash__=None at
5181 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5182 level.
5183
Nick Coghlanb028f502008-07-13 14:52:36 +00005184- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5185 the parent module cannot be found while performing an absolute import.
5186 This means that an incorrectly defined __package__ attribute will
5187 now only prevent relative imports in that module rather than causing
5188 all imports from that module to fail.
5189
Nick Coghlan14ff9942008-07-08 14:21:42 +00005190- Issue #2517: Allow unicode messages in Exceptions again by correctly

5200 another thread's dictionary.
5201
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005202- Issue #3004: Minor change to slice.indices(): the start and stop
5203 arguments are now treated identically, making the behaviour easier
5204 to describe and understand. For example, slice(None, -10,
5205 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5206 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5207 10, -1).
5208
Georg Brandl278fc502008-07-19 12:46:12 +00005209- Issue #3219: Calling a function with repeated keyword arguments,
5210 f(a=2, a=23), would not cause a syntax error. This was a regression
5211 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00005212
Georg Brandl278fc502008-07-19 12:46:12 +00005213- Issue #2862: Make int and float freelist management consistent with
5214 other freelists. Changes their CompactFreeList apis into
5215 ClearFreeList apis and calls them via gc.collect().

5221 api functions without holding the GIL, which could lead to a fatal
5222 error when they failed.
5223
Martin v. Löwisaabf4042008-08-02 07:20:25 +00005224- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005249- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5250 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005251 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005252 content-length. The problem had been corrected in the 2.4 branch, but never
5253 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005268- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
5269 handling is now the same as that of other special attributes like __name__).

5683- The PyString functions have been renamed to PyBytes. A batch of
5684 defines were added so that the linker still sees the original
5685 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005723- Issue #1631171: Re-implement the 'warnings' module in C (the
5724 original Python code has been kept as backup). This will allow for
5725 using the 'warning's machinery in such places as the parser where
5726 use of pure Python code is not possible. Both the ``showarning()``
5727 and ``formatwarning()`` gain an optional 'line' argument which is
5728 not called by default for backwards-compatibility reasons. Setting
5729 ``warnings.showwarning()`` to an implementation that lacks support
5730 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005772- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00005773 extension modules between 32 and 64 bit platforms. See the distutls

5786 so the controlled environment will more closely mirror the typical
5787 script environment. This supports setup.py scripts that refer to
5788 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005793- Issue #2550: The approach used by client/server code for obtaining
5794 ports to listen on in network-oriented tests has been refined in an
5795 effort to facilitate running multiple instances of the entire
5796 regression test suite in parallel without issue.
5797 test_support.bind_port() has been fixed such that it will always
5798 return a unique port -- which wasn't always the case with the
5799 previous implementation, especially if socket options had been set
5800 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5801 new implementation of bind_port() will actually raise an exception
5802 if it is passed an AF_INET/SOCK_STREAM socket with either the
5803 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5804 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5805 the socket it's been passed. This currently only applies to
5806 Windows. This option prevents any other sockets from binding to the
5807 host/port we've bound to, thus removing the possibility of the
5808 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5809 when a second SOCK_STREAM socket binds and accepts to a host/port
5810 that's already been bound by another socket. The optional preferred
5811 port parameter to bind_port() has been removed. Under no
5812 circumstances should tests be hard coding ports!
5813
5814 test_support.find_unused_port() has also been introduced, which will
5815 pass a temporary socket object to bind_port() in order to obtain an
5816 unused port. The temporary socket object is then closed and
5817 deleted, and the port is returned. This method should only be used
5818 for obtaining an unused port in order to pass to an external program
5819 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5820 a parameter to a server-oriented class that doesn't give you direct
5821 access to the underlying socket used.
5822
5823 Finally, test_support.HOST has been introduced, which should be used
5824 for the host argument of any relevant socket calls (i.e. bind and
5825 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005826
5827 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005828 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005829 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5830 test_asynchat and test_socket_ssl.
5831
Georg Brandl3ee81df2008-05-17 18:14:43 +00005832 It is now possible for multiple instances of the regression test
5833 suite to run in parallel without issue.

6101
Fred Drakea8ee94b2008-03-01 02:45:07 +00006102- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00006103 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00006104
Georg Brandlad61bc82008-02-23 15:11:18 +00006105- Issue #2067: file.__exit__() now calls subclasses' close() method.
6106

Christian Heimes5224d282008-02-23 15:01:05 +00006108
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006109- Issue #1881: An internal parser limit has been increased. Also see
Georg Brandl222e2082010-08-01 22:27:39 +00006110 issue #215555 for a discussion.
Facundo Batistafc2d0102008-02-23 12:01:13 +00006111
Eric Smitha73fbe72008-02-23 03:09:44 +00006112- Added the future_builtins module, which contains hex() and oct().
6113 These are the PEP 3127 version of these functions, designed to be
6114 compatible with the hex() and oct() builtins from Python 3.0. They
6115 differ slightly in their output formats from the existing, unchanged
6116 Python 2.6 builtins. The expected usage of the future_builtins
6117 module is:
6118 from future_builtins import hex, oct
6119
Eric Smith7ef40bf2008-02-20 23:34:22 +00006120- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6121 exponents for exponents with absolute value < 100. Follows C99
6122 standard. This is a change on Windows, which would use 3 digits.
6123 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6124 so that any alterations it does to the resulting string will be
6125 available in stringlib/formatter.h (for float.__format__).
6126
Eric Smith5a3c1352008-02-19 13:21:56 +00006127- Implemented PEP 3101, Advanced String Formatting. This adds a new
6128 builtin format(); a format() method for str and unicode; a
6129 __format__() method to object, str, unicode, int, long, float, and
6130 datetime; the class string.Formatter; and the C API
6131 PyObject_Format().
6132
Georg Brandl3ee81df2008-05-17 18:14:43 +00006133- Fixed several potential crashes, all caused by specially crafted
6134 __del__ methods exploiting objects in temporarily inconsistent
6135 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006136
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006137- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006138 prevent a possible crash: an Abstract Base Class would try to access
6139 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006144- Clear all free lists during a gc.collect() of the highest generation
6145 in order to allow pymalloc to free more arenas. Python may give back
6146 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006147
Georg Brandl3ee81df2008-05-17 18:14:43 +00006148- Issue #2045: Fix an infinite recursion triggered when printing a
6149 subclass of collections.defaultdict, if its default_factory is set
6150 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006151
Christian Heimesf75dbef2008-02-08 00:11:31 +00006152- Fixed a minor memory leak in dictobject.c. The content of the free
6153 list was not freed on interpreter shutdown.
6154
Georg Brandl21e99f42010-03-07 15:23:59 +00006155- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00006156 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00006157
Georg Brandl3ee81df2008-05-17 18:14:43 +00006158- Patch #1953: Added ``sys._compact_freelists()`` and the C API
6159 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006160 to compact the internal free lists of pre-allocted ints and floats.
6161
Georg Brandl3ee81df2008-05-17 18:14:43 +00006162- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6163 calls. Python expected the return type int but the fork familie
6164 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006165

Georg Brandl3ee81df2008-05-17 18:14:43 +00006178- Patch #1473257: generator objects gain a gi_code attribute. This is
6179 the same object as the func_code attribute of the function that
6180 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006181
Georg Brandl3ee81df2008-05-17 18:14:43 +00006182- Issue #1920: "while 0" statements were completely removed by the
6183 compiler, even in the presence of an "else" clause, which is
6184 supposed to be run when the condition is false. Now the compiler
6185 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006186
Guido van Rossumeead05f2008-01-24 18:21:02 +00006187- A few crashers fixed: weakref_in_del.py (issue #1377858);

Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006191- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006192 suppressed while an extension is loaded by calling SetErrorMode in
6193 dynload_win.c. The error is still reported properly.
6194
Georg Brandl3ee81df2008-05-17 18:14:43 +00006195- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006196 several extension methods and modules do not work without unicode
6197 support.
6198
Georg Brandl26543b12008-01-21 18:36:51 +00006199- Issue #1882: when compiling code from a string, encoding cookies in the
6200 second line of code were not always recognized correctly.
6201
Georg Brandl14404b62008-01-19 19:27:05 +00006202- Issue #1679: "0x" was taken as a valid integer literal.
6203
Georg Brandl6caad7d2008-01-26 14:19:22 +00006204- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006205 added.
6206
Christian Heimesc94e2b52008-01-14 04:13:37 +00006207- sys.float_info / PyFloat_GetInfo: The floating point information
6208 object was converted from a dict to a specialized structseq object.
6209
Georg Brandl3ee81df2008-05-17 18:14:43 +00006210- Patch #1816: Added sys.flags structseq. It exposes the status of
6211 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006212
Georg Brandl3ee81df2008-05-17 18:14:43 +00006213- Objects/structseq.c: Implemented new structseq representation. The
6214 patch makes structseqs (e.g. the return value of os.stat) more
6215 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006216
Georg Brandl3ee81df2008-05-17 18:14:43 +00006217- Patch #1700288: added a type attribute cache that caches method
6218 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006219
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006220- Bug #1776: __import__() no longer accepts filenames on any platform.
6221 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006222
Georg Brandlaed6c662008-01-07 17:25:53 +00006223- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6224
Georg Brandl3ee81df2008-05-17 18:14:43 +00006225- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6226 envvar and sys.dont_write_bytecode attribute. All these can be set
6227 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006228
Georg Brandl3ee81df2008-05-17 18:14:43 +00006229- Improve some exception messages when Windows fails to load an
6230 extension module. Now we get for example '%1 is not a valid Win32
6231 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006232
Georg Brandl3ee81df2008-05-17 18:14:43 +00006233- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006235- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6236 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006237
Christian Heimes0a8143f2007-12-18 23:22:54 +00006238- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006239 and INF. float("nan"), float("inf") and float("-inf") now work on
6240 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006241
Georg Brandl3ee81df2008-05-17 18:14:43 +00006242- Compiler now generates simpler and faster code for dictionary
6243 literals. The oparg for BUILD_MAP now indicates an estimated
6244 dictionary size. There is a new opcode, STORE_MAP, for adding
6245 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006249- Issue #1620: New property decorator syntax was modifying the
6250 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006251
Georg Brandl3ee81df2008-05-17 18:14:43 +00006252- Issue #1538: Avoid copying string in split/rsplit if the split char
6253 is not found.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006255- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006256 SystemError.
6257
Nick Coghlanef01d822007-12-03 12:55:17 +00006258- PEP 366: Allow explicit relative imports when executing modules
6259 inside packages with the -m switch via a new module level
6260 __package__ attribute.
6261
Georg Brandl3ee81df2008-05-17 18:14:43 +00006262- Issue #1402: Fix a crash on exit, when another thread is still
6263 running, and if the deallocation of its frames somehow calls the
6264 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006265

6270
Georg Brandl3ee81df2008-05-17 18:14:43 +00006271- Issue #1460: The utf-7 incremental decoder did not accept truncated
6272 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006273
Georg Brandl3ee81df2008-05-17 18:14:43 +00006274- Patch #1739468: Directories and zipfiles containing a __main__.py
6275 file can now be directly executed by passing their name to the
6276 interpreter. The directory/zipfile is automatically inserted as the
6277 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006278
Georg Brandl3ee81df2008-05-17 18:14:43 +00006279- Issue #1265: Fix a problem with sys.settrace, if the tracing
6280 function uses a generator expression when at the same time the
6281 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006282
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006283- sets and frozensets now have an isdisjoint() method.
6284
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006285- optimize the performance of builtin.sum().
6286
Neal Norwitz44f326e2007-10-05 05:29:17 +00006287- Fix warnings found by the new version of the Coverity checker.
6288
Georg Brandl21e99f42010-03-07 15:23:59 +00006289- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006290 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6291 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006292
Georg Brandl3ee81df2008-05-17 18:14:43 +00006293- Issue #1686386: Tuple's tp_repr did not take into account the
6294 possibility of having a self-referential tuple, which is possible
6295 from C code. Nor did object's tp_str consider that a type's tp_str
6296 could do something that could lead to an inifinite recursion.
6297 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6298 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006299
Georg Brandl3ee81df2008-05-17 18:14:43 +00006300- Issue #1164: It was possible to trigger deadlock when using the
6301 'print' statement to write to a file since the GIL was not released
6302 as needed. Now PyObject_Print() does the right thing along with
6303 various tp_print implementations of the built-in types and those in
6304 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006305
Georg Brandl3ee81df2008-05-17 18:14:43 +00006306- Issue #1147: Exceptions were directly allowing string exceptions in
6307 their throw() method even though string exceptions no longer
6308 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006309
Georg Brandl3ee81df2008-05-17 18:14:43 +00006310- Issue #1096: Prevent a segfault from getting the repr of a very
6311 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006312
Brett Cannon1e534b52007-09-07 04:18:30 +00006313- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006314 PyObject_Call() never calling back out to Python code to trigger
6315 recursion depth updates/checks. Required the creation of a static
6316 RuntimeError instance in case normalizing an exception put the
6317 recursion check value past its limit. Fixes crashers
6318 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006319
Georg Brandl3ee81df2008-05-17 18:14:43 +00006320- Patch #1031213: Decode source line in SyntaxErrors back to its
6321 original source encoding.

6324 with %G.
6325
Georg Brandl3ee81df2008-05-17 18:14:43 +00006326- Prevent expandtabs() on string and unicode objects from causing a
6327 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006328

Georg Brandla5ea6892007-06-01 11:33:33 +00006332
Neal Norwitz0ac60192007-05-27 04:08:54 +00006333- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006334 __*__ attributes. (Some already existed, e.g., __doc__ and
6335 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006336
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006337- Add -3 option to the interpreter to warn about features that are
6338 deprecated and will be changed/removed in Python 3.0.
6339
Georg Brandl2134e752007-05-21 20:34:16 +00006340- Patch #1686487: you can now pass any mapping after '**' in function
6341 calls.
6342
Collin Winter62903052007-05-18 23:11:24 +00006343- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006344 "except E as target:". This is to provide forwards compatibility
6345 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006346
Brett Cannon229cee22007-05-05 01:34:02 +00006347- Deprecate BaseException.message as per PEP 352.
6348
Georg Brandl3ee81df2008-05-17 18:14:43 +00006349- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006350 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006351
Vinay Sajip8549ce32007-05-06 17:53:37 +00006352- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006353 setting a plain string, ie don't expand to single letter identifiers.
6354
Raymond Hettinger13936692007-04-11 18:40:58 +00006355- Request #1191699: Slices can now be pickled.
6356
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006357- Request #1193128: str.translate() now allows a None argument for
6358 translations that only remove characters without re-mapping the
6359 remaining characters.
6360
Georg Brandl5cb76c12007-03-21 09:00:39 +00006361- Patch #1682205: a TypeError while unpacking an iterable is no longer
6362 masked by a generic one with the message "unpack non-sequence".
6363
Neal Norwitzaa754b72007-03-21 06:39:48 +00006364- Remove unused file Python/fmod.c.
6365
Guido van Rossum143b5642007-03-23 04:58:42 +00006366- Bug #1683368: The object.__init__() and object.__new__() methods are
6367 now stricter in rejecting excess arguments. The only time when
6368 either allows excess arguments is when it is not overridden and the
6369 other one is. For backwards compatibility, when both are
6370 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006371 warning later). Also, type.__init__() insists on the same signature
6372 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006373
Georg Brandl3ee81df2008-05-17 18:14:43 +00006374- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6375 object to complex using its __complex__() method before falling back
6376 to the __float__() method. Therefore, the functions in the cmath
6377 module now can operate on objects that define a __complex__()
6378 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006379
Georg Brandl3ee81df2008-05-17 18:14:43 +00006380- Patch #1623563: allow __class__ assignment for classes with
6381 __slots__. The old and the new class are still required to have the
6382 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006383
Georg Brandl3ee81df2008-05-17 18:14:43 +00006384- Patch #1642547: Fix an error/crash when encountering syntax errors
6385 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006387- Patch #1462488: Python no longer segfaults when
6388 ``object.__reduce_ex__()`` is called with an object that is faking
6389 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006390
Georg Brandl3ee81df2008-05-17 18:14:43 +00006391- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00006394- Patch #1444529: the builtin compile() now accepts keyword arguments.
6395
Georg Brandl7b9c5552007-03-12 14:30:05 +00006396- Bug #1678647: write a newline after printing an exception in any
6397 case, even when converting the value to a string failed.
6398
Georg Brandl871f1bc2007-03-12 13:17:36 +00006399- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006400 its argument, if it exists. If not, it will work like before. This
6401 allows customizing the output of dir() in the presence of a
6402 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006403
Collin Winter276887b2007-03-12 16:11:39 +00006404- Patch #922167: Python no longer segfaults when faced with infinitely
6405 self-recursive reload() calls (as reported by bug #742342).
6406
Georg Brandl3ee81df2008-05-17 18:14:43 +00006407- Patch #1675981: remove unreachable code from ``type.__new__()``
6408 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006410- Patch #1491866: change the complex() constructor to allow
6411 parthensized forms. This means complex(repr(x)) now works instead of
6412 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00006413
Georg Brandlaa2321b2007-03-07 00:40:28 +00006414- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00006415 makes the filenames the warning module prints much more sensible
6416 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00006417
Georg Brandl49aafc92007-03-07 00:34:46 +00006418- Variant of patch #697613: don't exit the interpreter on a SystemExit
6419 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00006420 variable is given, but break into the interactive interpreter just
6421 like on other exceptions or normal program exit.

6920
Georg Brandlfb4b3b72007-04-24 15:27:13 +00006921- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
6922 (as opposed to the command line) will now write file names ending in
6923 ".cpp" too.
6924
Facundo Batistad918a652007-04-24 13:54:38 +00006925- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006926 the client's request was successfully received, understood, and
6927 accepted. Now in these cases no error is raised in urllib (issue
6928 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00006929

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006936- Added a timeout parameter to the constructor of other protocols
6937 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6938 work started with create_connection() and timeout in httplib, and
6939 closes patch #723312.
6940
Vinay Sajip8549ce32007-05-06 17:53:37 +00006941- Patch #1676823: Added create_connection() to socket.py, which may be
6942 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00006943 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00006944
Martin v. Löwis0af33882007-03-23 13:27:15 +00006945- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006952- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
6953 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00006954 directories.
6955

6965
Georg Brandlf66b6032007-03-14 08:27:52 +00006966- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00006967 AttributeError instead of an IOError when the server's response
6968 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006969
Georg Brandl3ee81df2008-05-17 18:14:43 +00006970- Patch #957650: "%var%" environment variable references are now
6971 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl03b90d82007-03-13 22:07:36 +00006973
Georg Brandl3ee81df2008-05-17 18:14:43 +00006974- Patch #1429539: pdb now correctly initializes the __main__ module
6975 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006976 correctly now.
6977
Georg Brandlbad6f192007-03-13 21:32:56 +00006978- The nonobvious commands.getstatus() function is now deprecated.

6984
Georg Brandl3ee81df2008-05-17 18:14:43 +00006985- Patch #1530482: add pydoc.render_doc() which returns the
6986 documentation for a thing instead of paging it to stdout, which
6987 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00006988
Georg Brandl3ee81df2008-05-17 18:14:43 +00006989- Patch #1533909: the timeit module now accepts callables in addition

6995 parameter which can be set to False to prevent the default
6996 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00006998- Patch #1581073: add a flag to textwrap that prevents the dropping of
6999 whitespace while wrapping.
7000
Georg Brandl92a6bae2007-03-13 17:43:32 +00007001- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007002 are set for invalid interpolation sequences that would lead to
7003 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007004

Collin Winter22c42ba2007-03-10 02:51:26 +00007038

7046 returned string up to the first NUL character.
7047

7057
Georg Brandl3ee81df2008-05-17 18:14:43 +00007058- unittest now verifies more of its assumptions. In particular,
7059 TestCase and TestSuite subclasses (not instances) are no longer
7060 accepted in TestSuite.addTest(). This should cause no
7061 incompatibility since it never made sense with ordinary subclasses
7062 -- the failure just occurred later, with a more cumbersome
7063 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007064

7072 given a unicode argument and os.listdir() returns unicode filenames.
7073
Georg Brandl3ee81df2008-05-17 18:14:43 +00007074- Patch #1673619: setup.py identifies extension modules it doesn't

7076 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007452 time so that opening a database previously created with the DB_DUP
7453 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7454 opens. Specifically: dictionary assignment to a DB object will
7455 replace all values for a given key when the database allows
7456 duplicate values. DB users should use DB.put(k, v) when they want
7457 to store duplicates; not DB[k] = v.

7464 characters with ASCII value less than 32. Also, it correctly quotes
7465 dots only if they occur on a single line, as opposed to the previous
7466 behavior of quoting dots if they are the second character of any
7467 line.
