166

174 by Andrew Bennetts.
175
Raymond Hettinger74f869e2010-09-13 22:14:36 +0000176- Issue #9826: OrderedDict.__repr__ can now handle self-referential

185 This prevents user-created self-referencing ordered dictionaries from
186 becoming permanently uncollectable GC garbage. The downside is that
187 removing __del__ means that the internal doubly-linked list has to wait for
188 GC collection rather than freeing memory immediately when the refcnt drops
189 to zero.
190
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000191- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently
Victor Stinnerd2f6ae62010-10-12 22:53:51 +0000192 different internal state for small values of n. Fixed by salting the
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000193 value.
194
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000195- Issue #9792: In case of connection failure, socket.create_connection()
196 would swallow the exception and raise a new one, making it impossible
197 to fetch the original errno, or to filter timeout errors. Now the
198 original error is re-raised.
199
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000200- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,
201 and the passed buffer was exactly 1024 bytes long, the buffer wouldn't
202 be updated back after the system call. Original patch by Brian Brazil.
203
Antoine Pitroudca9de92010-09-04 17:52:26 +0000204- Issue #1100562: Fix deep-copying of objects derived from the list and
205 dict types. Patch by Michele Orrù and Björn Lindqvist.
206

208 ConfigParser.write.
209
Daniel Stutzbach66c981b2010-08-31 20:29:39 +0000210- Issue #808164: Fixed socket.close to avoid references to globals, to
211 avoid issues when socket.close is called from a __del__ method.
212
Senthil Kumaran7e8fd5e2010-08-26 06:20:13 +0000213- Issue #8797: urllib2 does a retry for Basic Authentication failure instead of

215
R. David Murray7c4bf552010-08-25 01:45:57 +0000216- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
217 character years even if the message contains RFC822 two character years.
218
Daniel Stutzbach91287322010-08-24 21:09:30 +0000219- Issue #8750: Fixed MutableSet's methods to correctly handle
220 reflexive operations, namely x -= x and x ^= x.
221
Victor Stinnercaafd772010-09-08 10:51:01 +0000222- Issue #9129: smtpd.py is vulnerable to DoS attacks deriving from missing
Giampaolo Rodolà8664d742010-08-23 22:48:51 +0000223 error handling when accepting a new connection.
224
Giampaolo Rodolà63308d72010-08-23 21:58:47 +0000225- Issue #658749: asyncore's connect() method now correctly interprets winsock

231 module now correctly return a set. (Patch by Eli Bendersky.)
232

234 ignored by the buffered IO layer anymore.
235
Benjamin Peterson52c36052010-08-21 03:03:22 +0000236- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
237 are not held onto after they are deleted elsewhere.
238
Raymond Hettingera54b2da2010-08-17 19:03:06 +0000239- Issue #9626: the view methods for collections.OrderedDict() were returning
240 the unordered versions inherited from dict. Those methods are now
241 overridden to provide ordered views.
242
Éric Araujo0389ae62010-08-14 03:07:46 +0000243- Issue #8688: MANIFEST files created by distutils now include a magic
244 comment indicating they are generated. Manually maintained MANIFESTs
245 without this marker will not be overwritten or removed.
246
Antoine Pitroue1436d12010-08-12 15:25:51 +0000247- Issue #7467: when reading a file from a ZIP archive, its CRC is checked

250
Antoine Pitroucb4f47c2010-08-11 13:40:17 +0000251- Issue #9550: a BufferedReader could issue an additional read when the

255
Fred Drake0a1fa0e2010-08-10 13:09:54 +0000256- Issue #9551: Don't raise TypeError when setting the value to None for

260 Interpreter Lock around all system calls. Original patch by Ryan Kelly.
261
Antoine Pitrou99009162010-08-09 22:51:24 +0000262- Issue #3757: thread-local objects now support cyclic garbage collection.

642
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000643- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
644 start byte and the continuation byte(s) are now considered invalid, instead
645 of the number of bytes specified by the start byte.
646 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
647 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
648 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
649 Previous versions returned a single u'\ufffd'.

Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000651- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000652 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
653 arises from the "Overriding __eq__ blocks inheritance ..." warning
654 when turned into an exception: in this case the exception simply
655 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000657- Issue #8748: Fix two issues with comparisons between complex and integer
658 objects. (1) The comparison could incorrectly return True in some cases
659 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
660 (2) The comparison raised an OverflowError for large integers, leading
661 to unpredictable exceptions when combining integers and complex objects
662 in sets or dicts.
663
Mark Dickinson81336372010-05-30 12:12:25 +0000664- Issue #5211: Implicit coercion for the complex type is now completely
665 removed. (Coercion for arithmetic operations was already removed in 2.7
666 alpha 4, but coercion for rich comparisons was accidentally left in.)
667
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000668- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

Georg Brandlfee0f442010-05-22 21:26:21 +00001034- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00001035 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00001044- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1045 with a non-empty format string. This is an effort to future-proof user
1046 code. If a derived class does not currently implement __format__ but later
1047 adds its own __format__, it would most likely break user code that had
1048 supplied a format string. This will be changed to a DeprecationWaring in
1049 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001082- Issue #8257: The Decimal construct now accepts a float instance directly,
1083 converting that float to a Decimal of equal value:

Raymond Hettinger34c35b22010-04-03 10:22:00 +00001088- collections.Counter() now supports a subtract() method.
1089
Georg Brandlfee0f442010-05-22 21:26:21 +00001090- The functools module now has a total_ordering() class decorator to simplify

Georg Brandlfee0f442010-05-22 21:26:21 +00001099- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1100 InvalidOperation instead of returning False. (Comparisons involving a quiet
1101 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1102 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001103
Georg Brandlfee0f442010-05-22 21:26:21 +00001104- Issue #2531: Comparison operations between floats and Decimal instances now
1105 return a result based on the numeric values of the operands; previously they
1106 returned an arbitrary result based on the relative ordering of id(float) and
1107 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001110 argument `-` which tells it to read files to compile from stdin. Each line is

Georg Brandlfee0f442010-05-22 21:26:21 +00001121- Comparisons using one of <, <=, >, >= between a complex instance and a
1122 Fractions instance now raise TypeError instead of returning True/False. This
1123 makes Fraction <=> complex comparisons consistent with int <=> complex, float

Georg Brandlba83f822010-03-14 09:50:54 +00001538 file position when calling `truncate()`. It would previously change the file
1539 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001540 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1543 class used to represent files stored inside an archive. The new
1544 implementation is significantly faster and can be wrapped in a

1546 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

1635-----------------
1636
Georg Brandlba83f822010-03-14 09:50:54 +00001637- The ``__complex__()`` method is now looked up on the class of instances to
1638 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00001639
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00001640- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,
1641 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
1642
Mark Dickinson1b34d252010-01-01 17:27:30 +00001643- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001644 DeprecationWarning when passed a float argument where an integer was expected.
1645 These functions and methods now raise TypeError instead. The majority of the
1646 effects of this change are in the extension modules, but some core functions
1647 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1648 and many unicode/str methods.

1659 used to drop the time part of the result.
1660
Georg Brandlba83f822010-03-14 09:50:54 +00001661- Issue #1811: Improve accuracy and cross-platform consistency for true division
1662 of integers: the result of a/b is now correctly rounded for ints a and b (at
1663 least on IEEE 754 platforms), and in particular does not depend on the
1664 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00001666- Issue #6108: ``unicode(exception)`` and ``str(exception)`` should return the

1672
Georg Brandlba83f822010-03-14 09:50:54 +00001673 These executables now work properly with the arch(1) command: ``arch -ppc
1674 python`` will start a universal binary version of python in PPC mode (unlike
1675 previous releases).

Georg Brandlba83f822010-03-14 09:50:54 +00001698 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

1832 decimal string that's guaranteed to round back to x under correct rounding
1833 (with round-half-to-even rounding mode). Previously it gave a string based on
1834 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1835 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1836 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00001838- Issue #7117: On almost all platforms: float-to-string and string-to-float
1839 conversions within Python are now correctly rounded. Places these conversions
1840 occur include: str for floats and complex numbers; the float and complex
1841 constructors; old-style and new-style numeric formatting; serialization and
1842 deserialization of floats and complex numbers using marshal, pickle and json;
1843 parsing of float and imaginary literals in Python code; Decimal-to-float
1844 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001845
Georg Brandlba83f822010-03-14 09:50:54 +00001846 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1847 providing correctly-rounded strtod and dtoa C functions. This code is
1848 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1849 the C compiler. There may be a small number of platforms on which correct
1850 operation of this code cannot be guaranteed, so the code is not used: notably,
1851 this applies to platforms where the C double format is not IEEE 754 binary64,
1852 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1853 and Python's configure script is unable to determine how to change the FPU
1854 precision. On these platforms conversions use the platform strtod and dtoa,
1855 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00001857- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1858 uses the correctly-rounded string <-> float conversions described above (when
1859 available), and so produces correctly rounded results that will display nicely
1860 under the float repr. There are two related small changes: (1) round now
1861 accepts any class with an ``__index__()`` method for its second argument (but
1862 no longer accepts floats for the second argument), and (2) an excessively
1863 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1864 raises an exception.

2214
Georg Brandlba83f822010-03-14 09:50:54 +00002215- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2216 file objects with closefd=False. The file descriptor is still kept open but
2217 the file object behaves like a closed file. The ``FileIO`` object also got a

2243 this code path is really executed because I cannot move to such directory on

2270 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

3447 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3448 neither __int__ nor __long__, TypeError used to be raised (with a

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003647- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3649 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3650 ``printf`` function, whereas PyString_FromFormat has an independent
3651 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon672237d2008-09-09 00:49:16 +00003722 return a list or None rather than a custom object.
3723
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003724- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00003748 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3749 for catch_warnings() also led to an improvement in the raising of a
3750 DeprecationWarning related to warnings.warn_explicit().
3751

3777 without limit.
3778
Benjamin Peterson37346b22008-08-23 20:27:43 +00003779- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003816What's New in Python 2.6 beta 3?
3817================================
3818
Barry Warsaw07a4a382008-08-21 01:15:08 +00003819*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003820
3821Core and Builtins
3822-----------------
3823
Guido van Rossumf8402962008-08-20 15:01:50 +00003824- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3825 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3826 extensions do not automatically benefit from the class attribute
3827 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3828 to their tp_flags field if they care. This is a backwards
3829 compatibility feature; in 3.0, all types will use the cache by
3830 default.
3831
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003832- Keyword arguments can now follow starred arguments. (``f(a, *args,
3833 keyword=23)`` is now valid syntax.)
3834
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003835- ctypes function pointers that are COM methods have a boolean True
3836 value again.
3837
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003838- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3839 by denying s# to parse objects that have a releasebuffer procedure,
3840 and introducing s*.
3841
Georg Brandl1e13ea92008-08-11 09:07:59 +00003842- Issue #3537: Fix an assertion failure when an empty but presized dict
3843 object was stored in the freelist.
3844
Mark Dickinsonb6467572008-08-04 21:30:09 +00003845- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3846 ValueError consistently across platforms.
3847
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003848- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3849 (64bit Unix, for example), unichr() would truncate its argument and return
3850 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3851
Neal Norwitze7d8be82008-07-31 17:17:14 +00003852- Apply security patches from Apple.
3853
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003854- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3855 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3856
Antoine Pitrou92f82162008-07-25 22:22:08 +00003857- Issue #1819: function calls with several named parameters are now on
3858 average 35% faster (as measured by pybench).
3859
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003860- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3861 the python debugger steps into a class statement: the free variables (local
3862 variables defined in an outer scope) would be deleted from the outer scope.
3863
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003864- Issue #2620: Overflow checking when allocating or reallocating memory
3865 was not always being done properly in some python types and extension
3866 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3867 all been updated to perform better checks and places in the code that
3868 would previously leak memory on the error path when such an allocation
3869 failed have been fixed.

3872-------
3873
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003874- Issue #3612: Added some missing basic types in ctypes.wintypes.
3875
Benjamin Petersone977ad42008-08-20 01:42:01 +00003876- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3877 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3878
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003879- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3880 version reported by these tools does not necessarily follow the python
3881 version numbering scheme, so the module is less strict when parsing it.
3882
Nick Coghlanf70385a2008-08-18 12:42:46 +00003883- Issue #2235: Added Py3k warnings for types which will become unhashable
3884 under the stricter __hash__ inheritance rules in 3.0. Several types
3885 which did not meet the rules for hash invariants and were already
3886 unhashable in 3.0 have now been explicitly flagged as unhashable in
3887 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3888 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3889
Brett Cannon88f801d2008-08-18 00:46:22 +00003890- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3891 imported into the module but exposed as part of the module's API.
3892
Brett Cannon7b96f072008-08-18 00:41:11 +00003893- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3894
Brett Cannon46225e72008-08-18 00:36:52 +00003895- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00003897- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
3898
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00003899- Issue #3575: Incremental decoder's decode function now takes bytearray
3900 by using 's*' instead of 't#'.
3901
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00003902- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00003903 fails unicode conversion on 2nd parameter. (windows only)
3904
Georg Brandl222e2082010-08-01 22:27:39 +00003905- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00003906 in a redirect.
3907
Brett Cannonabe423e2008-08-16 21:47:07 +00003908- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00003909 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00003910
Facundo Batistaeb90b782008-08-16 14:44:07 +00003911- Issue #2776: fixed small issue when handling an URL with double slash
3912 after a 302 response in the case of not going through a proxy.
3913
Antoine Pitroub90a8be2008-08-15 21:03:21 +00003914- Issue #2676: in the email package, content-type parsing was hanging on
3915 pathological input because of quadratic or exponential behaviour of a
3916 regular expression.
3917
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00003918- Issue #3476: binary buffered reading through the new "io" library is now
3919 thread-safe.
3920
Brett Cannonbf3157b2008-08-14 05:00:03 +00003921- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
3922 since mimetools itself is deprecated. Because modules are cached, all
3923 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
3924
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00003925- Issue #3134: shutil referenced undefined WindowsError symbol.
3926
Robert Schuppenies14646332008-08-10 11:01:53 +00003927- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
3928 menu entries were not deleted.
3929
Brett Cannon83e81842008-08-09 23:30:55 +00003930- Copied the implementation of reduce() to _functools.reduce() to have a
3931 version that did not raise a DeprecationWarning under -3.
3932
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00003933- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
3934 a MemoryError rather than silently stop the iteration.
3935
Guido van Rossum59ce9012008-08-09 14:55:34 +00003936- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
3937 to _sre.compile() will now be rejected. This should not affect anybody
3938 since the re.compile() function never generates invalid re-bytecode.
3939
Skip Montanaroa032bf42008-08-08 22:52:51 +00003940- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
3941 upon first access it can be automatically initialized from the csv file if
3942 it wasn't initialized during instantiation.
3943
Brett Cannon3aa2a492008-08-06 22:28:09 +00003944- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
3945 the reload() built-in has been removed.
3946
Brett Cannon7e30b672008-08-04 21:52:25 +00003947- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00003948 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

3951 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
3952 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
3953 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00003959 asking for a specific length. This problem only affected files opened
3960 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00003961
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00003962- Issue #3449: Update decimal module to use most recent specification
3963 (v. 1.68) and tests (v. 2.58) from IBM.

3988
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00003989- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

4002 interaction with the tp_hash slot (added in 2.6b2) are now documented
4003
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004004- Issue #643841: The language reference now provides more detailed

4011================================
4012
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004013*Release date: 17-Jul-2008*

4016-----------------
4017
Georg Brandl3e483f62008-07-16 22:57:41 +00004018- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4019 its methods now allow for items objects that can be converted to
4020 an integer using operator.index().
4021
Mark Dickinson64b7e502008-07-16 09:40:03 +00004022- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4023 produced a ValueError instead of giving the correct float.
4024
Eric Smitha5fa5a22008-07-16 00:11:49 +00004025- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4026 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4027
Mark Dickinson7103aa42008-07-15 19:08:33 +00004028- Issue #3008: the float type has a new instance method 'float.hex'
4029 and a new class method 'float.fromhex' to convert floating-point
4030 numbers to and from hexadecimal strings, respectively.
4031
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004032- Issue #2235: __hash__ is once again inherited by default. To allow
4033 collections.Hashable to remain meaningful in the presence of the
4034 default hash implementation (object.__hash__), it is now possible
4035 to explicit block inheritance of hash by setting __hash__=None at
4036 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4037 level.
4038
Nick Coghlanb028f502008-07-13 14:52:36 +00004039- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4040 the parent module cannot be found while performing an absolute import.
4041 This means that an incorrectly defined __package__ attribute will
4042 now only prevent relative imports in that module rather than causing
4043 all imports from that module to fail.
4044
Nick Coghlan14ff9942008-07-08 14:21:42 +00004045- Issue #2517: Allow unicode messages in Exceptions again by correctly

4050 set to a custom object whose write() method happens to install
4051 another file in sys.stdout.

4054 threading.local: the first member set by a thread could be saved in
4055 another thread's dictionary.
4056
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004057- Issue #3004: Minor change to slice.indices(): the start and stop
4058 arguments are now treated identically, making the behaviour easier
4059 to describe and understand. For example, slice(None, -10,
4060 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4061 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4062 10, -1).
4063
Georg Brandl278fc502008-07-19 12:46:12 +00004064- Issue #3219: Calling a function with repeated keyword arguments,
4065 f(a=2, a=23), would not cause a syntax error. This was a regression
4066 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004067
Georg Brandl278fc502008-07-19 12:46:12 +00004068- Issue #2862: Make int and float freelist management consistent with
4069 other freelists. Changes their CompactFreeList apis into
4070 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00004075- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
4076 api functions without holding the GIL, which could lead to a fatal
4077 error when they failed.
4078
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004079- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004104- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4105 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004106 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004107 content-length. The problem had been corrected in the 2.4 branch, but never
4108 merged into trunk.
4109
Georg Brandle78fbcc2008-07-05 10:13:36 +00004110- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004123- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4124 handling is now the same as that of other special attributes like __name__).
4125
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004126- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Issue #1631171: Re-implement the 'warnings' module in C (the
4579 original Python code has been kept as backup). This will allow for
4580 using the 'warning's machinery in such places as the parser where
4581 use of pure Python code is not possible. Both the ``showarning()``
4582 and ``formatwarning()`` gain an optional 'line' argument which is
4583 not called by default for backwards-compatibility reasons. Setting
4584 ``warnings.showwarning()`` to an implementation that lacks support
4585 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004648- Issue #2550: The approach used by client/server code for obtaining
4649 ports to listen on in network-oriented tests has been refined in an
4650 effort to facilitate running multiple instances of the entire
4651 regression test suite in parallel without issue.
4652 test_support.bind_port() has been fixed such that it will always
4653 return a unique port -- which wasn't always the case with the
4654 previous implementation, especially if socket options had been set
4655 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4656 new implementation of bind_port() will actually raise an exception
4657 if it is passed an AF_INET/SOCK_STREAM socket with either the
4658 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4659 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4660 the socket it's been passed. This currently only applies to
4661 Windows. This option prevents any other sockets from binding to the
4662 host/port we've bound to, thus removing the possibility of the
4663 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4664 when a second SOCK_STREAM socket binds and accepts to a host/port
4665 that's already been bound by another socket. The optional preferred
4666 port parameter to bind_port() has been removed. Under no
4667 circumstances should tests be hard coding ports!
4668
4669 test_support.find_unused_port() has also been introduced, which will
4670 pass a temporary socket object to bind_port() in order to obtain an
4671 unused port. The temporary socket object is then closed and
4672 deleted, and the port is returned. This method should only be used
4673 for obtaining an unused port in order to pass to an external program
4674 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4675 a parameter to a server-oriented class that doesn't give you direct
4676 access to the underlying socket used.
4677
4678 Finally, test_support.HOST has been introduced, which should be used
4679 for the host argument of any relevant socket calls (i.e. bind and
4680 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004681
4682 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004683 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004684 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4685 test_asynchat and test_socket_ssl.
4686
Georg Brandl3ee81df2008-05-17 18:14:43 +00004687 It is now possible for multiple instances of the regression test
4688 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00004967- Added the future_builtins module, which contains hex() and oct().
4968 These are the PEP 3127 version of these functions, designed to be
4969 compatible with the hex() and oct() builtins from Python 3.0. They
4970 differ slightly in their output formats from the existing, unchanged
4971 Python 2.6 builtins. The expected usage of the future_builtins
4972 module is:
4973 from future_builtins import hex, oct
4974
Eric Smith7ef40bf2008-02-20 23:34:22 +00004975- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4976 exponents for exponents with absolute value < 100. Follows C99
4977 standard. This is a change on Windows, which would use 3 digits.
4978 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4979 so that any alterations it does to the resulting string will be
4980 available in stringlib/formatter.h (for float.__format__).
4981
Eric Smith5a3c1352008-02-19 13:21:56 +00004982- Implemented PEP 3101, Advanced String Formatting. This adds a new
4983 builtin format(); a format() method for str and unicode; a
4984 __format__() method to object, str, unicode, int, long, float, and
4985 datetime; the class string.Formatter; and the C API
4986 PyObject_Format().
4987
Georg Brandl3ee81df2008-05-17 18:14:43 +00004988- Fixed several potential crashes, all caused by specially crafted
4989 __del__ methods exploiting objects in temporarily inconsistent
4990 state.

5016
Georg Brandl3ee81df2008-05-17 18:14:43 +00005017- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5018 calls. Python expected the return type int but the fork familie
5019 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005033- Patch #1473257: generator objects gain a gi_code attribute. This is
5034 the same object as the func_code attribute of the function that
5035 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005036
Georg Brandl3ee81df2008-05-17 18:14:43 +00005037- Issue #1920: "while 0" statements were completely removed by the
5038 compiler, even in the presence of an "else" clause, which is
5039 supposed to be run when the condition is false. Now the compiler
5040 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005041

Georg Brandl3ee81df2008-05-17 18:14:43 +00005050- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005051 several extension methods and modules do not work without unicode
5052 support.
5053
Georg Brandl26543b12008-01-21 18:36:51 +00005054- Issue #1882: when compiling code from a string, encoding cookies in the
5055 second line of code were not always recognized correctly.
5056
Georg Brandl14404b62008-01-19 19:27:05 +00005057- Issue #1679: "0x" was taken as a valid integer literal.
5058
Georg Brandl6caad7d2008-01-26 14:19:22 +00005059- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005060 added.
5061
Christian Heimesc94e2b52008-01-14 04:13:37 +00005062- sys.float_info / PyFloat_GetInfo: The floating point information
5063 object was converted from a dict to a specialized structseq object.
5064
Georg Brandl3ee81df2008-05-17 18:14:43 +00005065- Patch #1816: Added sys.flags structseq. It exposes the status of
5066 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005067
Georg Brandl3ee81df2008-05-17 18:14:43 +00005068- Objects/structseq.c: Implemented new structseq representation. The
5069 patch makes structseqs (e.g. the return value of os.stat) more
5070 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005071
Georg Brandl3ee81df2008-05-17 18:14:43 +00005072- Patch #1700288: added a type attribute cache that caches method
5073 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005074
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005075- Bug #1776: __import__() no longer accepts filenames on any platform.
5076 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005077
Georg Brandlaed6c662008-01-07 17:25:53 +00005078- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5079
Georg Brandl3ee81df2008-05-17 18:14:43 +00005080- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5081 envvar and sys.dont_write_bytecode attribute. All these can be set
5082 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005083
Georg Brandl3ee81df2008-05-17 18:14:43 +00005084- Improve some exception messages when Windows fails to load an
5085 extension module. Now we get for example '%1 is not a valid Win32
5086 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005087
Georg Brandl3ee81df2008-05-17 18:14:43 +00005088- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005090- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5091 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005092
Christian Heimes0a8143f2007-12-18 23:22:54 +00005093- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005094 and INF. float("nan"), float("inf") and float("-inf") now work on
5095 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005096
Georg Brandl3ee81df2008-05-17 18:14:43 +00005097- Compiler now generates simpler and faster code for dictionary
5098 literals. The oparg for BUILD_MAP now indicates an estimated
5099 dictionary size. There is a new opcode, STORE_MAP, for adding
5100 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005110- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005111 SystemError.
5112
Nick Coghlanef01d822007-12-03 12:55:17 +00005113- PEP 366: Allow explicit relative imports when executing modules
5114 inside packages with the -m switch via a new module level
5115 __package__ attribute.
5116
Georg Brandl3ee81df2008-05-17 18:14:43 +00005117- Issue #1402: Fix a crash on exit, when another thread is still
5118 running, and if the deallocation of its frames somehow calls the
5119 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00005120

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00005124 attribute of an empty cell object.
5125
Georg Brandl3ee81df2008-05-17 18:14:43 +00005126- Issue #1460: The utf-7 incremental decoder did not accept truncated
5127 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00005128
Georg Brandl3ee81df2008-05-17 18:14:43 +00005129- Patch #1739468: Directories and zipfiles containing a __main__.py
5130 file can now be directly executed by passing their name to the
5131 interpreter. The directory/zipfile is automatically inserted as the
5132 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005133
Georg Brandl3ee81df2008-05-17 18:14:43 +00005134- Issue #1265: Fix a problem with sys.settrace, if the tracing
5135 function uses a generator expression when at the same time the
5136 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005137
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005138- sets and frozensets now have an isdisjoint() method.
5139
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005140- optimize the performance of builtin.sum().
5141
Neal Norwitz44f326e2007-10-05 05:29:17 +00005142- Fix warnings found by the new version of the Coverity checker.
5143
Georg Brandl21e99f42010-03-07 15:23:59 +00005144- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005145 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5146 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005147
Georg Brandl3ee81df2008-05-17 18:14:43 +00005148- Issue #1686386: Tuple's tp_repr did not take into account the
5149 possibility of having a self-referential tuple, which is possible
5150 from C code. Nor did object's tp_str consider that a type's tp_str
5151 could do something that could lead to an inifinite recursion.
5152 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5153 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005154
Georg Brandl3ee81df2008-05-17 18:14:43 +00005155- Issue #1164: It was possible to trigger deadlock when using the
5156 'print' statement to write to a file since the GIL was not released
5157 as needed. Now PyObject_Print() does the right thing along with
5158 various tp_print implementations of the built-in types and those in
5159 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005160
Georg Brandl3ee81df2008-05-17 18:14:43 +00005161- Issue #1147: Exceptions were directly allowing string exceptions in
5162 their throw() method even though string exceptions no longer
5163 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005164
Georg Brandl3ee81df2008-05-17 18:14:43 +00005165- Issue #1096: Prevent a segfault from getting the repr of a very
5166 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005167
Brett Cannon1e534b52007-09-07 04:18:30 +00005168- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005169 PyObject_Call() never calling back out to Python code to trigger
5170 recursion depth updates/checks. Required the creation of a static
5171 RuntimeError instance in case normalizing an exception put the
5172 recursion check value past its limit. Fixes crashers
5173 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005174
Georg Brandl3ee81df2008-05-17 18:14:43 +00005175- Patch #1031213: Decode source line in SyntaxErrors back to its
5176 original source encoding.

5179 with %G.
5180
Georg Brandl3ee81df2008-05-17 18:14:43 +00005181- Prevent expandtabs() on string and unicode objects from causing a
5182 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00005183

Georg Brandla5ea6892007-06-01 11:33:33 +00005187
Neal Norwitz0ac60192007-05-27 04:08:54 +00005188- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005189 __*__ attributes. (Some already existed, e.g., __doc__ and
5190 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005191
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005192- Add -3 option to the interpreter to warn about features that are
5193 deprecated and will be changed/removed in Python 3.0.
5194
Georg Brandl2134e752007-05-21 20:34:16 +00005195- Patch #1686487: you can now pass any mapping after '**' in function
5196 calls.
5197
Collin Winter62903052007-05-18 23:11:24 +00005198- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005199 "except E as target:". This is to provide forwards compatibility
5200 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005201
Brett Cannon229cee22007-05-05 01:34:02 +00005202- Deprecate BaseException.message as per PEP 352.
5203
Georg Brandl3ee81df2008-05-17 18:14:43 +00005204- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005205 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005206
Vinay Sajip8549ce32007-05-06 17:53:37 +00005207- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005208 setting a plain string, ie don't expand to single letter identifiers.
5209
Raymond Hettinger13936692007-04-11 18:40:58 +00005210- Request #1191699: Slices can now be pickled.
5211
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005212- Request #1193128: str.translate() now allows a None argument for
5213 translations that only remove characters without re-mapping the
5214 remaining characters.
5215
Georg Brandl5cb76c12007-03-21 09:00:39 +00005216- Patch #1682205: a TypeError while unpacking an iterable is no longer
5217 masked by a generic one with the message "unpack non-sequence".
5218
Neal Norwitzaa754b72007-03-21 06:39:48 +00005219- Remove unused file Python/fmod.c.
5220
Guido van Rossum143b5642007-03-23 04:58:42 +00005221- Bug #1683368: The object.__init__() and object.__new__() methods are
5222 now stricter in rejecting excess arguments. The only time when
5223 either allows excess arguments is when it is not overridden and the
5224 other one is. For backwards compatibility, when both are
5225 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005226 warning later). Also, type.__init__() insists on the same signature
5227 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005228
Georg Brandl3ee81df2008-05-17 18:14:43 +00005229- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5230 object to complex using its __complex__() method before falling back
5231 to the __float__() method. Therefore, the functions in the cmath
5232 module now can operate on objects that define a __complex__()
5233 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005234
Georg Brandl3ee81df2008-05-17 18:14:43 +00005235- Patch #1623563: allow __class__ assignment for classes with
5236 __slots__. The old and the new class are still required to have the
5237 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005238
Georg Brandl3ee81df2008-05-17 18:14:43 +00005239- Patch #1642547: Fix an error/crash when encountering syntax errors
5240 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005242- Patch #1462488: Python no longer segfaults when
5243 ``object.__reduce_ex__()`` is called with an object that is faking
5244 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005245
Georg Brandl3ee81df2008-05-17 18:14:43 +00005246- Patch #1680015: Don't modify __slots__ tuple if it contains an
5247 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00005249- Patch #1444529: the builtin compile() now accepts keyword arguments.
5250
Georg Brandl7b9c5552007-03-12 14:30:05 +00005251- Bug #1678647: write a newline after printing an exception in any
5252 case, even when converting the value to a string failed.
5253
Georg Brandl871f1bc2007-03-12 13:17:36 +00005254- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005255 its argument, if it exists. If not, it will work like before. This
5256 allows customizing the output of dir() in the presence of a
5257 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005258
Collin Winter276887b2007-03-12 16:11:39 +00005259- Patch #922167: Python no longer segfaults when faced with infinitely
5260 self-recursive reload() calls (as reported by bug #742342).
5261
Georg Brandl3ee81df2008-05-17 18:14:43 +00005262- Patch #1675981: remove unreachable code from ``type.__new__()``
5263 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00005264
Georg Brandl3ee81df2008-05-17 18:14:43 +00005265- Patch #1491866: change the complex() constructor to allow
5266 parthensized forms. This means complex(repr(x)) now works instead of
5267 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005268
Georg Brandlaa2321b2007-03-07 00:40:28 +00005269- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005270 makes the filenames the warning module prints much more sensible
5271 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005272
Georg Brandl49aafc92007-03-07 00:34:46 +00005273- Variant of patch #697613: don't exit the interpreter on a SystemExit
5274 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005275 variable is given, but break into the interactive interpreter just
5276 like on other exceptions or normal program exit.
Georg Brandl49aafc92007-03-07 00:34:46 +00005277
Georg Brandl3ee81df2008-05-17 18:14:43 +00005278- Patch #1638879: don't accept strings with embedded NUL bytes in

Georg Brandl3ee81df2008-05-17 18:14:43 +00005281- Bug #1674503: close the file opened by execfile() in an error
5282 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005283
Georg Brandl0fca97a2007-03-05 22:28:08 +00005284- Patch #1674228: when assigning a slice (old-style), check for the
5285 sq_ass_slice instead of the sq_slice slot.
5286
Georg Brandl3ee81df2008-05-17 18:14:43 +00005287- When printing an unraisable error, don't print exceptions. before
5288 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00005780- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005781 the client's request was successfully received, understood, and
5782 accepted. Now in these cases no error is raised in urllib (issue
5783 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00005791- Added a timeout parameter to the constructor of other protocols
5792 (telnetlib, ftplib, smtplib and poplib). This is second part of the
5793 work started with create_connection() and timeout in httplib, and
5794 closes patch #723312.
5795
Vinay Sajip8549ce32007-05-06 17:53:37 +00005796- Patch #1676823: Added create_connection() to socket.py, which may be
5797 called with a timeout, and use it from httplib (whose HTTPConnection

5820
Georg Brandlf66b6032007-03-14 08:27:52 +00005821- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00005822 AttributeError instead of an IOError when the server's response
5823 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00005824
Georg Brandl3ee81df2008-05-17 18:14:43 +00005825- Patch #957650: "%var%" environment variable references are now
5826 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00005829- Patch #1429539: pdb now correctly initializes the __main__ module
5830 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00005831 correctly now.
5832

Georg Brandl3ee81df2008-05-17 18:14:43 +00005840- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00005853- Patch #1581073: add a flag to textwrap that prevents the dropping of
5854 whitespace while wrapping.
5855
Georg Brandl92a6bae2007-03-13 17:43:32 +00005856- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00005857 are set for invalid interpolation sequences that would lead to
5858 errors on reading back those values.

5901 returned string up to the first NUL character.
5902

5912
Georg Brandl3ee81df2008-05-17 18:14:43 +00005913- unittest now verifies more of its assumptions. In particular,
5914 TestCase and TestSuite subclasses (not instances) are no longer
5915 accepted in TestSuite.addTest(). This should cause no
5916 incompatibility since it never made sense with ordinary subclasses
5917 -- the failure just occurred later, with a more cumbersome
5918 exception.

5927 given a unicode argument and os.listdir() returns unicode filenames.
5928
Georg Brandl3ee81df2008-05-17 18:14:43 +00005929- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006307 time so that opening a database previously created with the DB_DUP
6308 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6309 opens. Specifically: dictionary assignment to a DB object will
6310 replace all values for a given key when the database allows
6311 duplicate values. DB users should use DB.put(k, v) when they want
6312 to store duplicates; not DB[k] = v.

6319 characters with ASCII value less than 32. Also, it correctly quotes
6320 dots only if they occur on a single line, as opposed to the previous
6321 behavior of quoting dots if they are the second character of any
6322 line.
