1116
1117- As of 2.7.8, the 32-bit-only installer will support OS X 10.5
1118 and later systems as is currently done for Python 3.x installers.
1119 For 2.7.7 only, we will provide three installers:
1120 the legacy deprecated 10.3+ 32-bit-only format;
1121 the newer 10.5+ 32-bit-only format;
1122 and the unchanged 10.6+ 64-/32-bit format.
1123 Although binary installers will no longer be available from
1124 python.org as of 2.7.8, it will still be possible to build from
1125 source on 10.3.9 and 10.4 systems if necessary.
1126 See Mac/BuildScript/README.txt for more information.

2508 32-bit-only installer Pythons on systems with Xcode 4 (currently
2509 OS X 10.8, 10.7, and optionally 10.6).
2510 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
2511 * Since Xcode 4 removes ppc support, extension module builds now
2512 check for ppc compiler support and by default remove ppc and
2513 ppc64 archs when they are not available.
2514 * Extension module builds now revert to using system installed
2515 headers and libs (/usr and /System/Library) if the SDK used
2516 to build the interpreter is not installed or has moved.
2517 * Try to avoid building extension modules with deprecated
2518 and problematic Apple llvm-gcc compiler. If original compiler
2519 is not available, use clang instead by default.

Ned Deily0d0ea482012-02-10 12:59:06 +01002963- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
2964 Distutils-based packages with C extension modules may fail because
2965 Apple has removed gcc-4.2, the version used to build python.org
2966 64-bit/32-bit Pythons. If the user does not explicitly override
2967 the default C compiler by setting the CC environment variable,
2968 Distutils will now attempt to compile extension modules with clang
2969 if gcc-4.2 is required but not found. Also as a convenience, if
2970 the user does explicitly set CC, substitute its value as the default
2971 compiler in the Distutils LDSHARED configuration variable for OS X.
2972 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
2973 SDK, neither of which are available in Xcode 4. This change does not
2974 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -07003224- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
3225 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
3226 interpreter process. This could cause failures in non-Distutils subprocesses
3227 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02003228 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07003229 deployment target only in the environment of each build subprocess. It is
3230 still possible to globally override the default by setting
3231 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
3232 greater or equal to the default value, the value with which the interpreter
3233 was built.

3263 the ticker doesn't have to wind down to zero from the old starting point
3264 before the new interval takes effect. And if the user increases the
3265 interval, it makes sure the new limit takes effect right away rather have an
3266 early task switch before recognizing the new interval.

4253 by Andrew Bennetts.

4262
Raymond Hettinger20397532010-09-12 02:11:45 +00004263- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
4264 This prevents user-created self-referencing ordered dictionaries from
4265 becoming permanently uncollectable GC garbage. The downside is that
4266 removing __del__ means that the internal doubly-linked list has to wait for
4267 GC collection rather than freeing memory immediately when the refcnt drops
4268 to zero.
4269
Raymond Hettingerffd2a422010-09-10 10:47:22 +00004270- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

4273
Antoine Pitrouc818ed42010-09-07 21:40:25 +00004274- Issue #9792: In case of connection failure, socket.create_connection()
4275 would swallow the exception and raise a new one, making it impossible
4276 to fetch the original errno, or to filter timeout errors. Now the
4277 original error is re-raised.
4278
Antoine Pitrouf4f61712010-09-07 16:34:47 +00004279- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
4280 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
4281 be updated back after the system call. Original patch by Brian Brazil.

4288
Daniel Stutzbach66c981b2010-08-31 20:29:39 +00004289- Issue #808164: Fixed socket.close to avoid references to globals, to
4290 avoid issues when socket.close is called from a __del__ method.
4291

4293 can be set to False to turn off the previously undocumented 'popularity'
4294 heuristic. Patch by Terry Reedy and Eli Bendersky
4295
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +00004296- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of
4297 falling into recursion.
4298
R. David Murray7c4bf552010-08-25 01:45:57 +00004299- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
4300 character years even if the message contains RFC822 two character years.
4301
Daniel Stutzbach91287322010-08-24 21:09:30 +00004302- Issue #8750: Fixed MutableSet's methods to correctly handle

Raymond Hettinger917bba12010-08-22 08:01:58 +00004313- Issue #9214: Set operations on KeysView or ItemsView in the collections
4314 module now correctly return a set. (Patch by Eli Bendersky.)
4315
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00004316- Issue #9617: Signals received during a low-level write operation aren't
4317 ignored by the buffered IO layer anymore.
4318
Benjamin Peterson52c36052010-08-21 03:03:22 +00004319- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
4320 are not held onto after they are deleted elsewhere.
4321
Raymond Hettingera54b2da2010-08-17 19:03:06 +00004322- Issue #9626: the view methods for collections.OrderedDict() were returning
4323 the unordered versions inherited from dict. Those methods are now
4324 overridden to provide ordered views.
4325
Éric Araujo0389ae62010-08-14 03:07:46 +00004326- Issue #8688: MANIFEST files created by distutils now include a magic
4327 comment indicating they are generated. Manually maintained MANIFESTs
4328 without this marker will not be overwritten or removed.
4329
Antoine Pitroue1436d12010-08-12 15:25:51 +00004330- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
4331 and a BadZipfile error is raised if it doesn't match (as used to be the
4332 case in Python 2.5 and earlier).
4333
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00004334- Issue #9550: a BufferedReader could issue an additional read when the
4335 original read request had been satisfied, which could block indefinitely
4336 when the underlying raw IO channel was e.g. a socket. Report and original
4337 patch by Jason V. Miller.
4338
Fred Drake0a1fa0e2010-08-10 13:09:54 +00004339- Issue #9551: Don't raise TypeError when setting the value to None for

Senthil Kumarane677ecf2010-08-08 11:56:31 +00004357- Fix Issue8280 - urllib2's Request method will remove fragements in the url.
4358 This is how it is supposed to work, wget and curl do the same. Previous
4359 behavior was wrong.

4367 the option character for the added 'h/help' option if prefix_chars
4368 does not contain a '-', instead of raising an error.
4369

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00004740- Issue #8748: Fix two issues with comparisons between complex and integer
4741 objects. (1) The comparison could incorrectly return True in some cases
4742 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
4743 (2) The comparison raised an OverflowError for large integers, leading
4744 to unpredictable exceptions when combining integers and complex objects
4745 in sets or dicts.

4992 indefinitely if the other end didn't respond.
4993
Georg Brandlfee0f442010-05-22 21:26:21 +00004994- The do_handshake() method of SSL objects now adjusts the blocking mode of the

Mark Dickinsond2f3e3f2010-05-05 22:23:58 +00005087 (Optimization was unintentionally turned on in gcc --with-pydebug builds in

5113
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00005114- Issue #8329: Don't return the same lists from select.select when no fds are
5115 changed.
5116
Georg Brandlfee0f442010-05-22 21:26:21 +00005117- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00005118 on 64-bit machines. The shift count for either left or right shift is
5119 permitted to be up to sys.maxsize.

Georg Brandlfee0f442010-05-22 21:26:21 +00005127- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
5128 with a non-empty format string. This is an effort to future-proof user
5129 code. If a derived class does not currently implement __format__ but later
5130 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00005131 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00005132 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00005165- Issue #8257: The Decimal construct now accepts a float instance directly,

Georg Brandlfee0f442010-05-22 21:26:21 +00005182- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
5183 InvalidOperation instead of returning False. (Comparisons involving a quiet
5184 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
5185 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00005186
Georg Brandlfee0f442010-05-22 21:26:21 +00005187- Issue #2531: Comparison operations between floats and Decimal instances now
5188 return a result based on the numeric values of the operands; previously they
5189 returned an arbitrary result based on the relative ordering of id(float) and
5190 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00005204- Comparisons using one of <, <=, >, >= between a complex instance and a
5205 Fractions instance now raise TypeError instead of returning True/False. This
5206 makes Fraction <=> complex comparisons consistent with int <=> complex, float
5207 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00005625 file position when calling `truncate()`. It would previously change the file
5626 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00005627 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

5630 class used to represent files stored inside an archive. The new
5631 implementation is significantly faster and can be wrapped in a

5633 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

5722-----------------
5723
Georg Brandlba83f822010-03-14 09:50:54 +00005724- The ``__complex__()`` method is now looked up on the class of instances to
5725 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00005726
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00005727- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

5729
Mark Dickinson1b34d252010-01-01 17:27:30 +00005730- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00005731 DeprecationWarning when passed a float argument where an integer was expected.
5732 These functions and methods now raise TypeError instead. The majority of the
5733 effects of this change are in the extension modules, but some core functions
5734 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
5735 and many unicode/str methods.

5747
Georg Brandlba83f822010-03-14 09:50:54 +00005748- Issue #1811: Improve accuracy and cross-platform consistency for true division
5749 of integers: the result of a/b is now correctly rounded for ints a and b (at
5750 least on IEEE 754 platforms), and in particular does not depend on the
5751 internal representation of a long.
Mark Dickinson46572832009-12-27 14:55:57 +00005752
Georg Brandlba83f822010-03-14 09:50:54 +00005753- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

Ronald Oussoren92919a62009-12-24 13:30:58 +00005758 executables on OSX.
5759
Georg Brandlba83f822010-03-14 09:50:54 +00005760 These executables now work properly with the arch(1) command: ``arch -ppc
5761 python`` will start a universal binary version of python in PPC mode (unlike
5762 previous releases).
Ronald Oussoren92919a62009-12-24 13:30:58 +00005763

Georg Brandlba83f822010-03-14 09:50:54 +00005784 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00005924- Issue #7117: On almost all platforms: float-to-string and string-to-float
5925 conversions within Python are now correctly rounded. Places these conversions
5926 occur include: str for floats and complex numbers; the float and complex
5927 constructors; old-style and new-style numeric formatting; serialization and
5928 deserialization of floats and complex numbers using marshal, pickle and json;
5929 parsing of float and imaginary literals in Python code; Decimal-to-float
5930 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00005931
Georg Brandlba83f822010-03-14 09:50:54 +00005932 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
5933 providing correctly-rounded strtod and dtoa C functions. This code is
5934 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
5935 the C compiler. There may be a small number of platforms on which correct
5936 operation of this code cannot be guaranteed, so the code is not used: notably,
5937 this applies to platforms where the C double format is not IEEE 754 binary64,
5938 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
5939 and Python's configure script is unable to determine how to change the FPU
5940 precision. On these platforms conversions use the platform strtod and dtoa,
5941 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00005943- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
5944 uses the correctly-rounded string <-> float conversions described above (when
5945 available), and so produces correctly rounded results that will display nicely
5946 under the float repr. There are two related small changes: (1) round now
5947 accepts any class with an ``__index__()`` method for its second argument (but
5948 no longer accepts floats for the second argument), and (2) an excessively
5949 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
5950 raises an exception.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00007757- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

7759 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
7760 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00007858 warnings.catch_warnings() along with some API cleanup. Expanding the tests
7859 for catch_warnings() also led to an improvement in the raising of a
7860 DeprecationWarning related to warnings.warn_explicit().

7887 without limit.
7888

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007926What's New in Python 2.6 beta 3?
7927================================
7928
Barry Warsaw07a4a382008-08-21 01:15:08 +00007929*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007930
7931Core and Builtins
7932-----------------
7933
Guido van Rossumf8402962008-08-20 15:01:50 +00007934- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
7935 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
7936 extensions do not automatically benefit from the class attribute
7937 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
7938 to their tp_flags field if they care. This is a backwards
7939 compatibility feature; in 3.0, all types will use the cache by
7940 default.
7941
Benjamin Petersonf647dc12008-08-20 01:27:30 +00007942- Keyword arguments can now follow starred arguments. (``f(a, *args,
7943 keyword=23)`` is now valid syntax.)
7944
Thomas Heller0ad5ae02008-08-19 19:25:04 +00007945- ctypes function pointers that are COM methods have a boolean True
7946 value again.
7947
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00007948- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
7949 by denying s# to parse objects that have a releasebuffer procedure,
7950 and introducing s*.
7951
Georg Brandl1e13ea92008-08-11 09:07:59 +00007952- Issue #3537: Fix an assertion failure when an empty but presized dict
7953 object was stored in the freelist.
7954
Mark Dickinsonb6467572008-08-04 21:30:09 +00007955- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
7956 ValueError consistently across platforms.
7957
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00007958- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
7959 (64bit Unix, for example), unichr() would truncate its argument and return
7960 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
7961
Neal Norwitze7d8be82008-07-31 17:17:14 +00007962- Apply security patches from Apple.
7963
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00007964- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
7965 PyErr_ExceptionMatches returns 0 when an exception occurs there.
7966
Antoine Pitrou92f82162008-07-25 22:22:08 +00007967- Issue #1819: function calls with several named parameters are now on
7968 average 35% faster (as measured by pybench).
7969
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00007970- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
7971 the python debugger steps into a class statement: the free variables (local
7972 variables defined in an outer scope) would be deleted from the outer scope.
7973
Gregory P. Smith0470bab2008-07-22 04:46:32 +00007974- Issue #2620: Overflow checking when allocating or reallocating memory
7975 was not always being done properly in some python types and extension
7976 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7977 all been updated to perform better checks and places in the code that
7978 would previously leak memory on the error path when such an allocation
7979 failed have been fixed.

7982-------
7983
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007984- Issue #3612: Added some missing basic types in ctypes.wintypes.
7985
Benjamin Petersone977ad42008-08-20 01:42:01 +00007986- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7987 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7988
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007989- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7990 version reported by these tools does not necessarily follow the python
7991 version numbering scheme, so the module is less strict when parsing it.
7992
Nick Coghlanf70385a2008-08-18 12:42:46 +00007993- Issue #2235: Added Py3k warnings for types which will become unhashable
7994 under the stricter __hash__ inheritance rules in 3.0. Several types
7995 which did not meet the rules for hash invariants and were already
7996 unhashable in 3.0 have now been explicitly flagged as unhashable in
7997 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7998 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7999
Brett Cannon88f801d2008-08-18 00:46:22 +00008000- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
8001 imported into the module but exposed as part of the module's API.
8002
Brett Cannon7b96f072008-08-18 00:41:11 +00008003- Remove an unneeded import of abc.ABCMeta from 'inspect'.
8004
Brett Cannon46225e72008-08-18 00:36:52 +00008005- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00008007- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
8008
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00008009- Issue #3575: Incremental decoder's decode function now takes bytearray
8010 by using 's*' instead of 't#'.
8011
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00008012- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00008013 fails unicode conversion on 2nd parameter. (windows only)
8014
Georg Brandl222e2082010-08-01 22:27:39 +00008015- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00008016 in a redirect.
8017
Brett Cannonabe423e2008-08-16 21:47:07 +00008018- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00008019 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00008020
Facundo Batistaeb90b782008-08-16 14:44:07 +00008021- Issue #2776: fixed small issue when handling an URL with double slash
8022 after a 302 response in the case of not going through a proxy.
8023
Antoine Pitroub90a8be2008-08-15 21:03:21 +00008024- Issue #2676: in the email package, content-type parsing was hanging on
8025 pathological input because of quadratic or exponential behaviour of a
8026 regular expression.
8027
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00008028- Issue #3476: binary buffered reading through the new "io" library is now
8029 thread-safe.
8030
Brett Cannonbf3157b2008-08-14 05:00:03 +00008031- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
8032 since mimetools itself is deprecated. Because modules are cached, all
8033 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
8034
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00008035- Issue #3134: shutil referenced undefined WindowsError symbol.
8036
Robert Schuppenies14646332008-08-10 11:01:53 +00008037- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
8038 menu entries were not deleted.
8039
Brett Cannon83e81842008-08-09 23:30:55 +00008040- Copied the implementation of reduce() to _functools.reduce() to have a
8041 version that did not raise a DeprecationWarning under -3.
8042
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00008043- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
8044 a MemoryError rather than silently stop the iteration.
8045
Guido van Rossum59ce9012008-08-09 14:55:34 +00008046- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
8047 to _sre.compile() will now be rejected. This should not affect anybody
8048 since the re.compile() function never generates invalid re-bytecode.
8049
Skip Montanaroa032bf42008-08-08 22:52:51 +00008050- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
8051 upon first access it can be automatically initialized from the csv file if
8052 it wasn't initialized during instantiation.
8053
Brett Cannon3aa2a492008-08-06 22:28:09 +00008054- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
8055 the reload() built-in has been removed.
8056
Brett Cannon7e30b672008-08-04 21:52:25 +00008057- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00008058 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

8061 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
8062 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
8063 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00008064

Antoine Pitroude781a42008-08-09 12:43:23 +00008069 asking for a specific length. This problem only affected files opened

8126-----------------
8127
Georg Brandl3e483f62008-07-16 22:57:41 +00008128- Issue #3156: Fix inconsistent behavior of the bytearray type: all
8129 its methods now allow for items objects that can be converted to
8130 an integer using operator.index().
8131
Mark Dickinson64b7e502008-07-16 09:40:03 +00008132- Issue #3360: Fix incorrect parsing of '020000000000.0', which
8133 produced a ValueError instead of giving the correct float.
8134
Eric Smitha5fa5a22008-07-16 00:11:49 +00008135- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
8136 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
8137
Mark Dickinson7103aa42008-07-15 19:08:33 +00008138- Issue #3008: the float type has a new instance method 'float.hex'
8139 and a new class method 'float.fromhex' to convert floating-point
8140 numbers to and from hexadecimal strings, respectively.
8141
Nick Coghlan6d6bd442008-07-15 15:40:22 +00008142- Issue #2235: __hash__ is once again inherited by default. To allow
8143 collections.Hashable to remain meaningful in the presence of the
8144 default hash implementation (object.__hash__), it is now possible
8145 to explicit block inheritance of hash by setting __hash__=None at
8146 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
8147 level.
8148
Nick Coghlanb028f502008-07-13 14:52:36 +00008149- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
8150 the parent module cannot be found while performing an absolute import.
8151 This means that an incorrectly defined __package__ attribute will
8152 now only prevent relative imports in that module rather than causing
8153 all imports from that module to fail.
8154
Nick Coghlan14ff9942008-07-08 14:21:42 +00008155- Issue #2517: Allow unicode messages in Exceptions again by correctly

8165 another thread's dictionary.
8166
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00008167- Issue #3004: Minor change to slice.indices(): the start and stop
8168 arguments are now treated identically, making the behaviour easier
8169 to describe and understand. For example, slice(None, -10,
8170 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
8171 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
8172 10, -1).

Georg Brandl278fc502008-07-19 12:46:12 +00008174- Issue #3219: Calling a function with repeated keyword arguments,
8175 f(a=2, a=23), would not cause a syntax error. This was a regression
8176 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008214- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
8215 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00008216 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00008217 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00008233- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

8643- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00008644
8645- The PyString functions have been renamed to PyBytes. A batch of
8646 defines were added so that the linker still sees the original
8647 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008685- Issue #1631171: Re-implement the 'warnings' module in C (the
8686 original Python code has been kept as backup). This will allow for
8687 using the 'warning's machinery in such places as the parser where
8688 use of pure Python code is not possible. Both the ``showarning()``
8689 and ``formatwarning()`` gain an optional 'line' argument which is
8690 not called by default for backwards-compatibility reasons. Setting
8691 ``warnings.showwarning()`` to an implementation that lacks support
8692 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008734- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00008735 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00008755- Issue #2550: The approach used by client/server code for obtaining
8756 ports to listen on in network-oriented tests has been refined in an
8757 effort to facilitate running multiple instances of the entire
8758 regression test suite in parallel without issue.
8759 test_support.bind_port() has been fixed such that it will always
8760 return a unique port -- which wasn't always the case with the
8761 previous implementation, especially if socket options had been set
8762 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
8763 new implementation of bind_port() will actually raise an exception
8764 if it is passed an AF_INET/SOCK_STREAM socket with either the
8765 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
8766 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
8767 the socket it's been passed. This currently only applies to
8768 Windows. This option prevents any other sockets from binding to the
8769 host/port we've bound to, thus removing the possibility of the
8770 'non-deterministic' behaviour, as Microsoft puts it, that occurs
8771 when a second SOCK_STREAM socket binds and accepts to a host/port
8772 that's already been bound by another socket. The optional preferred
8773 port parameter to bind_port() has been removed. Under no
8774 circumstances should tests be hard coding ports!
8775
8776 test_support.find_unused_port() has also been introduced, which will
8777 pass a temporary socket object to bind_port() in order to obtain an
8778 unused port. The temporary socket object is then closed and
8779 deleted, and the port is returned. This method should only be used
8780 for obtaining an unused port in order to pass to an external program
8781 (i.e. the -accept [port] argument to openssl's s_server mode) or as
8782 a parameter to a server-oriented class that doesn't give you direct
8783 access to the underlying socket used.
8784
8785 Finally, test_support.HOST has been introduced, which should be used
8786 for the host argument of any relevant socket calls (i.e. bind and
8787 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00008788
8789 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00008790 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00008791 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
8792 test_asynchat and test_socket_ssl.
8793
Georg Brandl3ee81df2008-05-17 18:14:43 +00008794 It is now possible for multiple instances of the regression test
8795 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00009074- Added the future_builtins module, which contains hex() and oct().
9075 These are the PEP 3127 version of these functions, designed to be
9076 compatible with the hex() and oct() builtins from Python 3.0. They
9077 differ slightly in their output formats from the existing, unchanged
9078 Python 2.6 builtins. The expected usage of the future_builtins
9079 module is:
9080 from future_builtins import hex, oct
9081
Eric Smith7ef40bf2008-02-20 23:34:22 +00009082- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
9083 exponents for exponents with absolute value < 100. Follows C99
9084 standard. This is a change on Windows, which would use 3 digits.
9085 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
9086 so that any alterations it does to the resulting string will be
9087 available in stringlib/formatter.h (for float.__format__).
9088
Eric Smith5a3c1352008-02-19 13:21:56 +00009089- Implemented PEP 3101, Advanced String Formatting. This adds a new
9090 builtin format(); a format() method for str and unicode; a
9091 __format__() method to object, str, unicode, int, long, float, and
9092 datetime; the class string.Formatter; and the C API
9093 PyObject_Format().
9094
Georg Brandl3ee81df2008-05-17 18:14:43 +00009095- Fixed several potential crashes, all caused by specially crafted
9096 __del__ methods exploiting objects in temporarily inconsistent
9097 state.

9108 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00009109
Georg Brandl3ee81df2008-05-17 18:14:43 +00009110- Issue #2045: Fix an infinite recursion triggered when printing a
9111 subclass of collections.defaultdict, if its default_factory is set
9112 to a bound method.

9123
Georg Brandl3ee81df2008-05-17 18:14:43 +00009124- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

Georg Brandl3ee81df2008-05-17 18:14:43 +00009140- Patch #1473257: generator objects gain a gi_code attribute. This is
9141 the same object as the func_code attribute of the function that
9142 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00009143
Georg Brandl3ee81df2008-05-17 18:14:43 +00009144- Issue #1920: "while 0" statements were completely removed by the
9145 compiler, even in the presence of an "else" clause, which is
9146 supposed to be run when the condition is false. Now the compiler
9147 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00009148

9155 dynload_win.c. The error is still reported properly.
9156
Georg Brandl3ee81df2008-05-17 18:14:43 +00009157- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00009158 several extension methods and modules do not work without unicode
9159 support.
9160
Georg Brandl26543b12008-01-21 18:36:51 +00009161- Issue #1882: when compiling code from a string, encoding cookies in the
9162 second line of code were not always recognized correctly.
9163
Georg Brandl14404b62008-01-19 19:27:05 +00009164- Issue #1679: "0x" was taken as a valid integer literal.
9165
Georg Brandl6caad7d2008-01-26 14:19:22 +00009166- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00009167 added.
9168
Christian Heimesc94e2b52008-01-14 04:13:37 +00009169- sys.float_info / PyFloat_GetInfo: The floating point information
9170 object was converted from a dict to a specialized structseq object.
9171
Georg Brandl3ee81df2008-05-17 18:14:43 +00009172- Patch #1816: Added sys.flags structseq. It exposes the status of
9173 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00009174
Georg Brandl3ee81df2008-05-17 18:14:43 +00009175- Objects/structseq.c: Implemented new structseq representation. The
9176 patch makes structseqs (e.g. the return value of os.stat) more
9177 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00009178
Georg Brandl3ee81df2008-05-17 18:14:43 +00009179- Patch #1700288: added a type attribute cache that caches method
9180 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00009181
Neal Norwitz3fc15b82008-01-10 05:42:58 +00009182- Bug #1776: __import__() no longer accepts filenames on any platform.
9183 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00009184
Georg Brandlaed6c662008-01-07 17:25:53 +00009185- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
9186
Georg Brandl3ee81df2008-05-17 18:14:43 +00009187- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
9188 envvar and sys.dont_write_bytecode attribute. All these can be set
9189 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00009190
Georg Brandl3ee81df2008-05-17 18:14:43 +00009191- Improve some exception messages when Windows fails to load an
9192 extension module. Now we get for example '%1 is not a valid Win32
9193 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00009194
Georg Brandl3ee81df2008-05-17 18:14:43 +00009195- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009197- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
9198 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00009199
Christian Heimes0a8143f2007-12-18 23:22:54 +00009200- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00009201 and INF. float("nan"), float("inf") and float("-inf") now work on
9202 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00009203
Georg Brandl3ee81df2008-05-17 18:14:43 +00009204- Compiler now generates simpler and faster code for dictionary
9205 literals. The oparg for BUILD_MAP now indicates an estimated
9206 dictionary size. There is a new opcode, STORE_MAP, for adding
9207 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009211- Issue #1620: New property decorator syntax was modifying the
9212 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00009213
Georg Brandl3ee81df2008-05-17 18:14:43 +00009214- Issue #1538: Avoid copying string in split/rsplit if the split char
9215 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00009216
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00009217- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00009218 SystemError.
9219
Nick Coghlanef01d822007-12-03 12:55:17 +00009220- PEP 366: Allow explicit relative imports when executing modules
9221 inside packages with the -m switch via a new module level
9222 __package__ attribute.
9223
Georg Brandl3ee81df2008-05-17 18:14:43 +00009224- Issue #1402: Fix a crash on exit, when another thread is still
9225 running, and if the deallocation of its frames somehow calls the
9226 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00009227

9232
Georg Brandl3ee81df2008-05-17 18:14:43 +00009233- Issue #1460: The utf-7 incremental decoder did not accept truncated
9234 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00009235
Georg Brandl3ee81df2008-05-17 18:14:43 +00009236- Patch #1739468: Directories and zipfiles containing a __main__.py
9237 file can now be directly executed by passing their name to the
9238 interpreter. The directory/zipfile is automatically inserted as the
9239 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00009240
Georg Brandl3ee81df2008-05-17 18:14:43 +00009241- Issue #1265: Fix a problem with sys.settrace, if the tracing
9242 function uses a generator expression when at the same time the
9243 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00009244
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00009245- sets and frozensets now have an isdisjoint() method.
9246
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00009247- optimize the performance of builtin.sum().
9248
Neal Norwitz44f326e2007-10-05 05:29:17 +00009249- Fix warnings found by the new version of the Coverity checker.
9250
Georg Brandl21e99f42010-03-07 15:23:59 +00009251- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00009252 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
9253 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00009254
Georg Brandl3ee81df2008-05-17 18:14:43 +00009255- Issue #1686386: Tuple's tp_repr did not take into account the
9256 possibility of having a self-referential tuple, which is possible
9257 from C code. Nor did object's tp_str consider that a type's tp_str
9258 could do something that could lead to an inifinite recursion.
9259 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
9260 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00009261
Georg Brandl3ee81df2008-05-17 18:14:43 +00009262- Issue #1164: It was possible to trigger deadlock when using the
9263 'print' statement to write to a file since the GIL was not released
9264 as needed. Now PyObject_Print() does the right thing along with
9265 various tp_print implementations of the built-in types and those in
9266 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00009267
Georg Brandl3ee81df2008-05-17 18:14:43 +00009268- Issue #1147: Exceptions were directly allowing string exceptions in
9269 their throw() method even though string exceptions no longer
9270 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00009271
Georg Brandl3ee81df2008-05-17 18:14:43 +00009272- Issue #1096: Prevent a segfault from getting the repr of a very
9273 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00009274
Brett Cannon1e534b52007-09-07 04:18:30 +00009275- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00009276 PyObject_Call() never calling back out to Python code to trigger
9277 recursion depth updates/checks. Required the creation of a static
9278 RuntimeError instance in case normalizing an exception put the
9279 recursion check value past its limit. Fixes crashers
9280 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00009281
Georg Brandl3ee81df2008-05-17 18:14:43 +00009282- Patch #1031213: Decode source line in SyntaxErrors back to its

9286 with %G.
9287
Georg Brandl3ee81df2008-05-17 18:14:43 +00009288- Prevent expandtabs() on string and unicode objects from causing a
9289 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00009290

Georg Brandla5ea6892007-06-01 11:33:33 +00009294
Neal Norwitz0ac60192007-05-27 04:08:54 +00009295- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00009296 __*__ attributes. (Some already existed, e.g., __doc__ and
9297 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00009298
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00009299- Add -3 option to the interpreter to warn about features that are
9300 deprecated and will be changed/removed in Python 3.0.
9301
Georg Brandl2134e752007-05-21 20:34:16 +00009302- Patch #1686487: you can now pass any mapping after '**' in function
9303 calls.
9304
Collin Winter62903052007-05-18 23:11:24 +00009305- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00009306 "except E as target:". This is to provide forwards compatibility
9307 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00009308
Brett Cannon229cee22007-05-05 01:34:02 +00009309- Deprecate BaseException.message as per PEP 352.
9310
Georg Brandl3ee81df2008-05-17 18:14:43 +00009311- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00009312 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00009313
Vinay Sajip8549ce32007-05-06 17:53:37 +00009314- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00009315 setting a plain string, ie don't expand to single letter identifiers.
9316
Raymond Hettinger13936692007-04-11 18:40:58 +00009317- Request #1191699: Slices can now be pickled.
9318
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00009319- Request #1193128: str.translate() now allows a None argument for
9320 translations that only remove characters without re-mapping the
9321 remaining characters.
9322
Georg Brandl5cb76c12007-03-21 09:00:39 +00009323- Patch #1682205: a TypeError while unpacking an iterable is no longer
9324 masked by a generic one with the message "unpack non-sequence".
9325
Neal Norwitzaa754b72007-03-21 06:39:48 +00009326- Remove unused file Python/fmod.c.
9327
Guido van Rossum143b5642007-03-23 04:58:42 +00009328- Bug #1683368: The object.__init__() and object.__new__() methods are
9329 now stricter in rejecting excess arguments. The only time when
9330 either allows excess arguments is when it is not overridden and the
9331 other one is. For backwards compatibility, when both are
9332 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00009333 warning later). Also, type.__init__() insists on the same signature
9334 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00009335
Georg Brandl3ee81df2008-05-17 18:14:43 +00009336- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
9337 object to complex using its __complex__() method before falling back
9338 to the __float__() method. Therefore, the functions in the cmath
9339 module now can operate on objects that define a __complex__()
9340 method.
Georg Brandl2b869942007-03-17 16:08:45 +00009341
Georg Brandl3ee81df2008-05-17 18:14:43 +00009342- Patch #1623563: allow __class__ assignment for classes with
9343 __slots__. The old and the new class are still required to have the
9344 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00009345
Georg Brandl3ee81df2008-05-17 18:14:43 +00009346- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00009349- Patch #1462488: Python no longer segfaults when
9350 ``object.__reduce_ex__()`` is called with an object that is faking
9351 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00009352
Georg Brandl3ee81df2008-05-17 18:14:43 +00009353- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00009356- Patch #1444529: the builtin compile() now accepts keyword arguments.
9357
Georg Brandl7b9c5552007-03-12 14:30:05 +00009358- Bug #1678647: write a newline after printing an exception in any
9359 case, even when converting the value to a string failed.
9360
Georg Brandl871f1bc2007-03-12 13:17:36 +00009361- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00009362 its argument, if it exists. If not, it will work like before. This
9363 allows customizing the output of dir() in the presence of a
9364 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00009365
Collin Winter276887b2007-03-12 16:11:39 +00009366- Patch #922167: Python no longer segfaults when faced with infinitely
9367 self-recursive reload() calls (as reported by bug #742342).
9368
Georg Brandl3ee81df2008-05-17 18:14:43 +00009369- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00009372- Patch #1491866: change the complex() constructor to allow
9373 parthensized forms. This means complex(repr(x)) now works instead of
9374 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00009375
Georg Brandlaa2321b2007-03-07 00:40:28 +00009376- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00009377 makes the filenames the warning module prints much more sensible
9378 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00009379
Georg Brandl49aafc92007-03-07 00:34:46 +00009380- Variant of patch #697613: don't exit the interpreter on a SystemExit
9381 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00009382 variable is given, but break into the interactive interpreter just
9383 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00009388- Bug #1674503: close the file opened by execfile() in an error
9389 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00009390

9883 (as opposed to the command line) will now write file names ending in
9884 ".cpp" too.
9885
Facundo Batistad918a652007-04-24 13:54:38 +00009886- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009887 the client's request was successfully received, understood, and
9888 accepted. Now in these cases no error is raised in urllib (issue
9889 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00009890

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00009897- Added a timeout parameter to the constructor of other protocols
9898 (telnetlib, ftplib, smtplib and poplib). This is second part of the
9899 work started with create_connection() and timeout in httplib, and
9900 closes patch #723312.
9901
Vinay Sajip8549ce32007-05-06 17:53:37 +00009902- Patch #1676823: Added create_connection() to socket.py, which may be
9903 called with a timeout, and use it from httplib (whose HTTPConnection

Georg Brandl3ee81df2008-05-17 18:14:43 +00009928 AttributeError instead of an IOError when the server's response
9929 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00009930

9936 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00009937 correctly now.
9938

Georg Brandl3ee81df2008-05-17 18:14:43 +00009946- Patch #1530482: add pydoc.render_doc() which returns the
9947 documentation for a thing instead of paging it to stdout, which

9961
Georg Brandl92a6bae2007-03-13 17:43:32 +00009962- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00009963 are set for invalid interpolation sequences that would lead to
9964 errors on reading back those values.

10007 returned string up to the first NUL character.

10018
Georg Brandl3ee81df2008-05-17 18:14:43 +000010019- unittest now verifies more of its assumptions. In particular,
10020 TestCase and TestSuite subclasses (not instances) are no longer
10021 accepted in TestSuite.addTest(). This should cause no

10023 -- the failure just occurred later, with a more cumbersome
10024 exception.

10389 complex, tuple, list, dict, set, and frozenset. Formerly, it would
10390 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +000010406- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +000010407 time so that opening a database previously created with the DB_DUP
10408 or DB_DUPSORT flag set will keep the proper behavior on subsequent
10409 opens. Specifically: dictionary assignment to a DB object will
10410 replace all values for a given key when the database allows
10411 duplicate values. DB users should use DB.put(k, v) when they want
10412 to store duplicates; not DB[k] = v.

10419 characters with ASCII value less than 32. Also, it correctly quotes
10420 dots only if they occur on a single line, as opposed to the previous
10421 behavior of quoting dots if they are the second character of any
10422 line.
