70 type is specified. Patch by Brian Curtin.
71
Antoine Pitrouca5a06a2010-01-27 21:48:46 +000072- Issue #6939: Fix file I/O objects in the `io` module to keep the original
73 file position when calling `truncate()`. It would previously change the
74 file position to the given argument, which goes against the tradition of
75 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

79
Tarek Ziadé495517c2010-01-24 00:57:20 +000080- Issue #7748: Since unicode values are supported for some metadata options

97
Tarek Ziadé06426fc2010-01-11 22:54:57 +000098- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

108
Antoine Pitrou0b074572010-01-08 19:21:34 +0000109- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
110 renaming of `cPickle` to `pickle`. The warning was annoying since there's
111 no alternative to cPickle if you care about performance. Patch by Florent
112 Xicluna.
113
Antoine Pitrou8dba7272010-01-07 18:04:12 +0000114- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

123
Senthil Kumaran81163642009-12-20 06:32:46 +0000124- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

126
Benjamin Peterson95671122009-12-13 17:34:05 +0000127- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

149
Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000150- Issue #7318: multiprocessing now uses a timeout when it fails to establish
151 a connection with another process, rather than looping endlessly. The
152 default timeout is 20 seconds, which should be amply sufficient for
153 local connections.
154
Antoine Pitrouc747d3a2009-11-09 16:47:50 +0000155- Issue #7282: Fix a memory leak when an RLock was used in a thread other

157 `thread.start_new_thread()`.
158

168 LP64 platforms (most 64-bit Linux, bsd, unix systems).
169
Gregory P. Smith6da85f92009-11-01 18:31:13 +0000170- Issue #7246 & Issue #7208: getpass now properly flushes input before
171 reading from stdin so that existing input does not confuse it and
172 lead to incorrect entry or an IOError. It also properly flushes it
173 afterwards to avoid the terminal echoing the input afterwards on
174 OSes such as Solaris.

180 sure that they accept an int or long as the second argument. Also
181 fix buggy handling of large arguments (those with coefficient longer
182 than the current precision) in shift and rotate.
183
R. David Murray7034db32009-10-27 23:39:06 +0000184- Issue #7082: When falling back to the MIME 'name' parameter, the
185 correct place to look for it is the Content-Type header.
186
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000187- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
188 larger than emax.
189
Antoine Pitrouf3a0ff62009-10-27 17:46:09 +0000190- Issue #7205: Fix a possible deadlock when using a BZ2File object from
191 several threads at once.
192

194 is too large to fit in the current precision.
195
Matthias Kloseb9ba2bb2010-01-16 10:31:22 +0000196- Issue #1488943: difflib.Differ() doesn't always add hints for tab characters

1113What's New in Python 2.6.1
1114==========================
1115
1116*Release date: 04-Dec-2008*
1117
1118Core and Builtins
1119-----------------
1120
1121- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1122 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1123 instead of throwing a MemoryError.
1124
1125- Issue #4367: Python would segfault during compiling when the unicodedata
1126 module couldn't be imported and \N escapes were present.
1127
1128- Issue #4348: Some bytearray methods returned that didn't cause any change to
1129 the bytearray, returned the same bytearray instead of a copy.
1130
1131- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1132
1133- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1134
1135- Issue #4048: The parser module now correctly validates relative imports.
1136
1137- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1142
1143- Issue #4209: Enabling unicode_literals and the print_function in the same
1144 __future__ import didn't work.
1145
1146- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1147 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1148 really executed because I cannot move to such directory on win2k)
1149
1150- Issue #4069: When set.remove(element) is used with a set element, the element
1151 is temporarily replaced with an equivalent frozenset. But the eventual
1152 KeyError would always report the empty frozenset([]) as the missing key. Now
1153 it correctly refers to the initial element.
1154
1155- Fixed C99 style comments in several files. Python is now C89 compatible
1156 again.

1306 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1307 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1308 ``printf`` function, whereas PyString_FromFormat has an independent
1309 implementation and uses "%zd" on all platforms for size_t values.
1310 This makes a difference on win64, where ``printf`` needs "%Id" to display
1311 64bit values.
1312
Benjamin Peterson97179b02008-09-09 20:55:01 +00001313- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1314 error.
1315
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001316- Issue #3777: long() applied to a float object now always return a long
1317 object; previously an int would be returned for small values. the __long__
1318 method is allowed to return either an int or a long, but the behaviour of
1319 float objects should not change to respect backward compatibility.
1320
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001321- Issue #3751: str.rpartition would perform a left-partition when called with
1322 a unicode argument.
1323
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001324- Issue #3683: Fix compilation when --without-threads is given.
1325
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001326- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001327 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001328 was correctly parsed but parsing of subsequent arguments failed.
1329
Vinay Sajip35e3b032008-09-01 14:33:59 +00001330- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001331 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1332 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1333 when given a tuple of classes as second argument, were looking up
1334 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1335 type object.
1336
Neal Norwitz18aa3882008-08-24 05:04:52 +00001337- Fix crashes on memory allocation failure found with failmalloc.
1338
1339- Fix memory leaks found with valgrind and update suppressions file.
1340
1341- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1342
1343- Fix problem using wrong name in decimal module reported by pychecker.
1344
Christian Heimes7d4c3172008-08-22 19:47:25 +00001345- Silenced another compiler warning about a used but not defined
1346 function 'stringlib_contains_obj'.
1347
Benjamin Peterson712ee922008-08-24 18:10:20 +00001348- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1349 ``__delslice__``.

1353
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001354- Issue #1204: The configure script now tests for additional libraries
1355 that may be required when linking against readline. This fixes issues
1356 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00001405- Issue 3602: Moved test.test_support.catch_warning() to
1406 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1407 for catch_warnings() also led to an improvement in the raising of a
1408 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001430- Issue #2975: When compiling several extension modules with Visual Studio 2008
1431 from the same python interpreter, some environment variables would grow
1432 without limit.
1433
Benjamin Peterson37346b22008-08-23 20:27:43 +00001434- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001471What's New in Python 2.6 beta 3?
1472================================
1473
Barry Warsaw07a4a382008-08-21 01:15:08 +00001474*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001475
1476Core and Builtins
1477-----------------
1478
Guido van Rossumf8402962008-08-20 15:01:50 +00001479- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1480 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1481 extensions do not automatically benefit from the class attribute
1482 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1483 to their tp_flags field if they care. This is a backwards
1484 compatibility feature; in 3.0, all types will use the cache by
1485 default.
1486
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001487- Keyword arguments can now follow starred arguments. (``f(a, *args,
1488 keyword=23)`` is now valid syntax.)
1489
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001490- ctypes function pointers that are COM methods have a boolean True
1491 value again.
1492
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001493- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1494 by denying s# to parse objects that have a releasebuffer procedure,
1495 and introducing s*.
1496
Georg Brandl1e13ea92008-08-11 09:07:59 +00001497- Issue #3537: Fix an assertion failure when an empty but presized dict
1498 object was stored in the freelist.
1499
Mark Dickinsonb6467572008-08-04 21:30:09 +00001500- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1501 ValueError consistently across platforms.
1502
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001503- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1504 (64bit Unix, for example), unichr() would truncate its argument and return
1505 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1506
Neal Norwitze7d8be82008-07-31 17:17:14 +00001507- Apply security patches from Apple.
1508
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001509- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1510 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1511
Antoine Pitrou92f82162008-07-25 22:22:08 +00001512- Issue #1819: function calls with several named parameters are now on
1513 average 35% faster (as measured by pybench).
1514
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001515- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1516 the python debugger steps into a class statement: the free variables (local
1517 variables defined in an outer scope) would be deleted from the outer scope.
1518
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001519- Issue #2620: Overflow checking when allocating or reallocating memory
1520 was not always being done properly in some python types and extension
1521 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1522 all been updated to perform better checks and places in the code that
1523 would previously leak memory on the error path when such an allocation
1524 failed have been fixed.

1527-------
1528
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001529- Issue #3612: Added some missing basic types in ctypes.wintypes.
1530
Benjamin Petersone977ad42008-08-20 01:42:01 +00001531- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1532 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1533
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001534- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1535 version reported by these tools does not necessarily follow the python
1536 version numbering scheme, so the module is less strict when parsing it.
1537
Nick Coghlanf70385a2008-08-18 12:42:46 +00001538- Issue #2235: Added Py3k warnings for types which will become unhashable
1539 under the stricter __hash__ inheritance rules in 3.0. Several types
1540 which did not meet the rules for hash invariants and were already
1541 unhashable in 3.0 have now been explicitly flagged as unhashable in
1542 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1543 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1544
Brett Cannon88f801d2008-08-18 00:46:22 +00001545- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1546 imported into the module but exposed as part of the module's API.
1547
Brett Cannon7b96f072008-08-18 00:41:11 +00001548- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1549
Brett Cannon46225e72008-08-18 00:36:52 +00001550- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1551
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001552- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1553
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001554- Issue #3575: Incremental decoder's decode function now takes bytearray
1555 by using 's*' instead of 't#'.
1556
Jesus Cea585ad8a2009-07-02 15:37:21 +00001557- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001558 fails unicode conversion on 2nd parameter. (windows only)
1559
Facundo Batista94f243a2008-08-17 03:38:39 +00001560- Issue 2464. urllib2 now supports a malformation in the URL received
1561 in a redirect.
1562
Brett Cannonabe423e2008-08-16 21:47:07 +00001563- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001564 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001565
Facundo Batistaeb90b782008-08-16 14:44:07 +00001566- Issue #2776: fixed small issue when handling an URL with double slash
1567 after a 302 response in the case of not going through a proxy.
1568
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001569- Issue #2676: in the email package, content-type parsing was hanging on
1570 pathological input because of quadratic or exponential behaviour of a
1571 regular expression.
1572
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001573- Issue #3476: binary buffered reading through the new "io" library is now
1574 thread-safe.
1575
Brett Cannonbf3157b2008-08-14 05:00:03 +00001576- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1577 since mimetools itself is deprecated. Because modules are cached, all
1578 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1579
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001580- Issue #3134: shutil referenced undefined WindowsError symbol.
1581
Robert Schuppenies14646332008-08-10 11:01:53 +00001582- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1583 menu entries were not deleted.
1584
Brett Cannon83e81842008-08-09 23:30:55 +00001585- Copied the implementation of reduce() to _functools.reduce() to have a
1586 version that did not raise a DeprecationWarning under -3.
1587
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001588- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1589 a MemoryError rather than silently stop the iteration.
1590
Guido van Rossum59ce9012008-08-09 14:55:34 +00001591- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1592 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00001614 asking for a specific length. This problem only affected files opened

1671-----------------
1672
Georg Brandl3e483f62008-07-16 22:57:41 +00001673- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1674 its methods now allow for items objects that can be converted to
1675 an integer using operator.index().
1676
Mark Dickinson64b7e502008-07-16 09:40:03 +00001677- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1678 produced a ValueError instead of giving the correct float.
1679
Eric Smitha5fa5a22008-07-16 00:11:49 +00001680- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1681 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1682
Mark Dickinson7103aa42008-07-15 19:08:33 +00001683- Issue #3008: the float type has a new instance method 'float.hex'
1684 and a new class method 'float.fromhex' to convert floating-point
1685 numbers to and from hexadecimal strings, respectively.
1686
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001687- Issue #2235: __hash__ is once again inherited by default. To allow
1688 collections.Hashable to remain meaningful in the presence of the
1689 default hash implementation (object.__hash__), it is now possible
1690 to explicit block inheritance of hash by setting __hash__=None at
1691 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1692 level.
1693
Nick Coghlanb028f502008-07-13 14:52:36 +00001694- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1695 the parent module cannot be found while performing an absolute import.
1696 This means that an incorrectly defined __package__ attribute will
1697 now only prevent relative imports in that module rather than causing
1698 all imports from that module to fail.
1699
Nick Coghlan14ff9942008-07-08 14:21:42 +00001700- Issue #2517: Allow unicode messages in Exceptions again by correctly

1710 another thread's dictionary.
1711
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001712- Issue #3004: Minor change to slice.indices(): the start and stop
1713 arguments are now treated identically, making the behaviour easier
1714 to describe and understand. For example, slice(None, -10,
1715 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1716 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1717 10, -1).
1718
Georg Brandl278fc502008-07-19 12:46:12 +00001719- Issue #3219: Calling a function with repeated keyword arguments,
1720 f(a=2, a=23), would not cause a syntax error. This was a regression
1721 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001723- Issue #2862: Make int and float freelist management consistent with
1724 other freelists. Changes their CompactFreeList apis into

1731 api functions without holding the GIL, which could lead to a fatal
1732 error when they failed.
1733
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001734- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001759- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1760 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001761 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001762 content-length. The problem had been corrected in the 2.4 branch, but never
1763 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001778- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2166
Brett Cannonb61d8012008-05-11 23:39:04 +00002167- ``Lib/lib-old`` is now added to sys.path.
2168
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002169- On MacOS X it is now possible to install the framework in 64-bit
2170 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002171 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002172
2173 This is controlled by the configure argument ``--with-universal-archs``:
2174
2175 - ``--with-universal-archs=all``: install 4-way universal
2176
2177 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2178
2179 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2180
2181 This option should be used in combination with ``--enable-universalsdk=``.
2182
2183 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2191- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002192
2193- The PyString functions have been renamed to PyBytes. A batch of
2194 defines were added so that the linker still sees the original
2195 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002233- Issue #1631171: Re-implement the 'warnings' module in C (the
2234 original Python code has been kept as backup). This will allow for
2235 using the 'warning's machinery in such places as the parser where
2236 use of pure Python code is not possible. Both the ``showarning()``
2237 and ``formatwarning()`` gain an optional 'line' argument which is
2238 not called by default for backwards-compatibility reasons. Setting
2239 ``warnings.showwarning()`` to an implementation that lacks support
2240 for the ``line`` argument will raise a DeprecationWarning.

2264
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002265- The getpass module has been improved on Unix. It now uses /dev/tty
2266 by default and uses stderr instead of stdout. A GetPassWarning is
2267 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002268

Georg Brandl3ee81df2008-05-17 18:14:43 +00002282- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002283 extension modules between 32 and 64 bit platforms. See the distutls

2287 threads at once without fear of crashing the Python interpreter. If
2288 file.close() is called while an object is in use by another thread
2289 an IOError exception will be raised and the file will not be closed.
2290
Thomas Hellerf7906482008-04-04 19:43:25 +00002291- The bundled libffi copy is now in sync with the recently released

2296 so the controlled environment will more closely mirror the typical
2297 script environment. This supports setup.py scripts that refer to
2298 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002303- Issue #2550: The approach used by client/server code for obtaining
2304 ports to listen on in network-oriented tests has been refined in an
2305 effort to facilitate running multiple instances of the entire
2306 regression test suite in parallel without issue.
2307 test_support.bind_port() has been fixed such that it will always
2308 return a unique port -- which wasn't always the case with the
2309 previous implementation, especially if socket options had been set
2310 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2311 new implementation of bind_port() will actually raise an exception
2312 if it is passed an AF_INET/SOCK_STREAM socket with either the
2313 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2314 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2315 the socket it's been passed. This currently only applies to
2316 Windows. This option prevents any other sockets from binding to the
2317 host/port we've bound to, thus removing the possibility of the
2318 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2319 when a second SOCK_STREAM socket binds and accepts to a host/port
2320 that's already been bound by another socket. The optional preferred
2321 port parameter to bind_port() has been removed. Under no
2322 circumstances should tests be hard coding ports!
2323
2324 test_support.find_unused_port() has also been introduced, which will
2325 pass a temporary socket object to bind_port() in order to obtain an
2326 unused port. The temporary socket object is then closed and
2327 deleted, and the port is returned. This method should only be used
2328 for obtaining an unused port in order to pass to an external program
2329 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2330 a parameter to a server-oriented class that doesn't give you direct
2331 access to the underlying socket used.
2332
2333 Finally, test_support.HOST has been introduced, which should be used
2334 for the host argument of any relevant socket calls (i.e. bind and
2335 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002336
2337 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002338 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002339 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2340 test_asynchat and test_socket_ssl.
2341
Georg Brandl3ee81df2008-05-17 18:14:43 +00002342 It is now possible for multiple instances of the regression test
2343 suite to run in parallel without issue.

2610-----------------
2611
Fred Drakea8ee94b2008-03-01 02:45:07 +00002612- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002613 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002618
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002619- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002620 issue 215555 for a discussion.
2621
Eric Smitha73fbe72008-02-23 03:09:44 +00002622- Added the future_builtins module, which contains hex() and oct().
2623 These are the PEP 3127 version of these functions, designed to be
2624 compatible with the hex() and oct() builtins from Python 3.0. They
2625 differ slightly in their output formats from the existing, unchanged
2626 Python 2.6 builtins. The expected usage of the future_builtins
2627 module is:
2628 from future_builtins import hex, oct
2629
Eric Smith7ef40bf2008-02-20 23:34:22 +00002630- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2631 exponents for exponents with absolute value < 100. Follows C99
2632 standard. This is a change on Windows, which would use 3 digits.
2633 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2634 so that any alterations it does to the resulting string will be
2635 available in stringlib/formatter.h (for float.__format__).
2636
Eric Smith5a3c1352008-02-19 13:21:56 +00002637- Implemented PEP 3101, Advanced String Formatting. This adds a new
2638 builtin format(); a format() method for str and unicode; a
2639 __format__() method to object, str, unicode, int, long, float, and
2640 datetime; the class string.Formatter; and the C API
2641 PyObject_Format().
2642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Fixed several potential crashes, all caused by specially crafted
2644 __del__ methods exploiting objects in temporarily inconsistent
2645 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002646
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002647- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002648 prevent a possible crash: an Abstract Base Class would try to access
2649 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002654- Clear all free lists during a gc.collect() of the highest generation
2655 in order to allow pymalloc to free more arenas. Python may give back
2656 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002657
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658- Issue #2045: Fix an infinite recursion triggered when printing a
2659 subclass of collections.defaultdict, if its default_factory is set
2660 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002661
Christian Heimesf75dbef2008-02-08 00:11:31 +00002662- Fixed a minor memory leak in dictobject.c. The content of the free
2663 list was not freed on interpreter shutdown.
2664
Georg Brandl3ee81df2008-05-17 18:14:43 +00002665- Limit free list of method and builtin function objects to 256
2666 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002668- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2669 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002670 to compact the internal free lists of pre-allocted ints and floats.
2671
Georg Brandl3ee81df2008-05-17 18:14:43 +00002672- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2673 calls. Python expected the return type int but the fork familie
2674 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002675
Georg Brandl3ee81df2008-05-17 18:14:43 +00002676- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2683 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002684
Georg Brandl3ee81df2008-05-17 18:14:43 +00002685- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2686 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Patch #1473257: generator objects gain a gi_code attribute. This is
2689 the same object as the func_code attribute of the function that
2690 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002691
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692- Issue #1920: "while 0" statements were completely removed by the
2693 compiler, even in the presence of an "else" clause, which is
2694 supposed to be run when the condition is false. Now the compiler
2695 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002696
Guido van Rossumeead05f2008-01-24 18:21:02 +00002697- A few crashers fixed: weakref_in_del.py (issue #1377858);
2698 loosing_dict_ref.py (issue #1303614, test67.py);
2699 borrowed_ref_[34].py (not in tracker).
2700
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002701- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002702 suppressed while an extension is loaded by calling SetErrorMode in
2703 dynload_win.c. The error is still reported properly.
2704
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002706 several extension methods and modules do not work without unicode
2707 support.
2708
Georg Brandl26543b12008-01-21 18:36:51 +00002709- Issue #1882: when compiling code from a string, encoding cookies in the
2710 second line of code were not always recognized correctly.
2711
Georg Brandl14404b62008-01-19 19:27:05 +00002712- Issue #1679: "0x" was taken as a valid integer literal.
2713
Georg Brandl6caad7d2008-01-26 14:19:22 +00002714- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002715 added.
2716
Christian Heimesc94e2b52008-01-14 04:13:37 +00002717- sys.float_info / PyFloat_GetInfo: The floating point information
2718 object was converted from a dict to a specialized structseq object.
2719
Georg Brandl3ee81df2008-05-17 18:14:43 +00002720- Patch #1816: Added sys.flags structseq. It exposes the status of
2721 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002722
Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Objects/structseq.c: Implemented new structseq representation. The
2724 patch makes structseqs (e.g. the return value of os.stat) more
2725 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002726
Georg Brandl3ee81df2008-05-17 18:14:43 +00002727- Patch #1700288: added a type attribute cache that caches method
2728 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002729
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002730- Bug #1776: __import__() no longer accepts filenames on any platform.
2731 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002732
Georg Brandlaed6c662008-01-07 17:25:53 +00002733- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2734
Georg Brandl3ee81df2008-05-17 18:14:43 +00002735- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2736 envvar and sys.dont_write_bytecode attribute. All these can be set
2737 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002738
Georg Brandl3ee81df2008-05-17 18:14:43 +00002739- Improve some exception messages when Windows fails to load an
2740 extension module. Now we get for example '%1 is not a valid Win32
2741 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002742
Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00002744
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2746 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002747
Christian Heimes0a8143f2007-12-18 23:22:54 +00002748- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002749 and INF. float("nan"), float("inf") and float("-inf") now work on
2750 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002751
Georg Brandl3ee81df2008-05-17 18:14:43 +00002752- Compiler now generates simpler and faster code for dictionary
2753 literals. The oparg for BUILD_MAP now indicates an estimated
2754 dictionary size. There is a new opcode, STORE_MAP, for adding
2755 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002756
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00002758
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759- Issue #1620: New property decorator syntax was modifying the
2760 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002761
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762- Issue #1538: Avoid copying string in split/rsplit if the split char
2763 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002764
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002765- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002766 SystemError.
2767
Nick Coghlanef01d822007-12-03 12:55:17 +00002768- PEP 366: Allow explicit relative imports when executing modules

2770 __package__ attribute.
2771
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- Issue #1402: Fix a crash on exit, when another thread is still
2773 running, and if the deallocation of its frames somehow calls the
2774 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002775

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002779 attribute of an empty cell object.
2780
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781- Issue #1460: The utf-7 incremental decoder did not accept truncated
2782 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784- Patch #1739468: Directories and zipfiles containing a __main__.py
2785 file can now be directly executed by passing their name to the
2786 interpreter. The directory/zipfile is automatically inserted as the
2787 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002788
Georg Brandl3ee81df2008-05-17 18:14:43 +00002789- Issue #1265: Fix a problem with sys.settrace, if the tracing
2790 function uses a generator expression when at the same time the
2791 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002792
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002793- sets and frozensets now have an isdisjoint() method.
2794
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002795- optimize the performance of builtin.sum().
2796
Neal Norwitz44f326e2007-10-05 05:29:17 +00002797- Fix warnings found by the new version of the Coverity checker.
2798
Georg Brandl3ee81df2008-05-17 18:14:43 +00002799- The enumerate() builtin function is no longer bounded to sequences
2800 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2801 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002802
Georg Brandl3ee81df2008-05-17 18:14:43 +00002803- Issue #1686386: Tuple's tp_repr did not take into account the
2804 possibility of having a self-referential tuple, which is possible
2805 from C code. Nor did object's tp_str consider that a type's tp_str
2806 could do something that could lead to an inifinite recursion.
2807 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2808 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002809
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810- Issue #1164: It was possible to trigger deadlock when using the
2811 'print' statement to write to a file since the GIL was not released
2812 as needed. Now PyObject_Print() does the right thing along with
2813 various tp_print implementations of the built-in types and those in
2814 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002815
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Issue #1147: Exceptions were directly allowing string exceptions in
2817 their throw() method even though string exceptions no longer
2818 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002819
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- Issue #1096: Prevent a segfault from getting the repr of a very
2821 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002822
Brett Cannon1e534b52007-09-07 04:18:30 +00002823- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824 PyObject_Call() never calling back out to Python code to trigger
2825 recursion depth updates/checks. Required the creation of a static
2826 RuntimeError instance in case normalizing an exception put the
2827 recursion check value past its limit. Fixes crashers
2828 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002829
Georg Brandl3ee81df2008-05-17 18:14:43 +00002830- Patch #1031213: Decode source line in SyntaxErrors back to its
2831 original source encoding.

Georg Brandl7c3b50d2007-07-12 08:38:00 +00002833- Patch #1673759: add a missing overflow check when formatting floats
2834 with %G.
2835
Georg Brandl3ee81df2008-05-17 18:14:43 +00002836- Prevent expandtabs() on string and unicode objects from causing a
2837 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002838

Georg Brandla5ea6892007-06-01 11:33:33 +00002842
Neal Norwitz0ac60192007-05-27 04:08:54 +00002843- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002844 __*__ attributes. (Some already existed, e.g., __doc__ and
2845 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002846
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002847- Add -3 option to the interpreter to warn about features that are
2848 deprecated and will be changed/removed in Python 3.0.
2849
Georg Brandl2134e752007-05-21 20:34:16 +00002850- Patch #1686487: you can now pass any mapping after '**' in function
2851 calls.
2852
Collin Winter62903052007-05-18 23:11:24 +00002853- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854 "except E as target:". This is to provide forwards compatibility
2855 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002856
Brett Cannon229cee22007-05-05 01:34:02 +00002857- Deprecate BaseException.message as per PEP 352.
2858
Georg Brandl3ee81df2008-05-17 18:14:43 +00002859- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002860 inherited from a builtin base.
2861
Vinay Sajip8549ce32007-05-06 17:53:37 +00002862- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002863 setting a plain string, ie don't expand to single letter identifiers.
2864
Raymond Hettinger13936692007-04-11 18:40:58 +00002865- Request #1191699: Slices can now be pickled.
2866
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002867- Request #1193128: str.translate() now allows a None argument for
2868 translations that only remove characters without re-mapping the
2869 remaining characters.
2870
Georg Brandl5cb76c12007-03-21 09:00:39 +00002871- Patch #1682205: a TypeError while unpacking an iterable is no longer
2872 masked by a generic one with the message "unpack non-sequence".
2873
Neal Norwitzaa754b72007-03-21 06:39:48 +00002874- Remove unused file Python/fmod.c.
2875
Guido van Rossum143b5642007-03-23 04:58:42 +00002876- Bug #1683368: The object.__init__() and object.__new__() methods are
2877 now stricter in rejecting excess arguments. The only time when
2878 either allows excess arguments is when it is not overridden and the
2879 other one is. For backwards compatibility, when both are
2880 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002881 warning later). Also, type.__init__() insists on the same signature
2882 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002883
Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2885 object to complex using its __complex__() method before falling back
2886 to the __float__() method. Therefore, the functions in the cmath
2887 module now can operate on objects that define a __complex__()
2888 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002889
Georg Brandl3ee81df2008-05-17 18:14:43 +00002890- Patch #1623563: allow __class__ assignment for classes with
2891 __slots__. The old and the new class are still required to have the
2892 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002893
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002897- Patch #1462488: Python no longer segfaults when
2898 ``object.__reduce_ex__()`` is called with an object that is faking
2899 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002900
Georg Brandl3ee81df2008-05-17 18:14:43 +00002901- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002904- Patch #1444529: the builtin compile() now accepts keyword arguments.
2905
Georg Brandl7b9c5552007-03-12 14:30:05 +00002906- Bug #1678647: write a newline after printing an exception in any
2907 case, even when converting the value to a string failed.
2908
Georg Brandl871f1bc2007-03-12 13:17:36 +00002909- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002910 its argument, if it exists. If not, it will work like before. This
2911 allows customizing the output of dir() in the presence of a
2912 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002913
Collin Winter276887b2007-03-12 16:11:39 +00002914- Patch #922167: Python no longer segfaults when faced with infinitely
2915 self-recursive reload() calls (as reported by bug #742342).
2916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Patch #1675981: remove unreachable code from ``type.__new__()``
2918 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- Patch #1491866: change the complex() constructor to allow
2921 parthensized forms. This means complex(repr(x)) now works instead of
2922 raising a ValueError.

Georg Brandl4e933132006-09-06 20:05:58 +00003027- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

3433 ".cpp" too.
3434
Facundo Batistad918a652007-04-24 13:54:38 +00003435- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003436 the client's request was successfully received, understood, and
3437 accepted. Now in these cases no error is raised in urllib (issue
3438 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003439

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003446- Added a timeout parameter to the constructor of other protocols
3447 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3448 work started with create_connection() and timeout in httplib, and
3449 closes patch #723312.
3450
Vinay Sajip8549ce32007-05-06 17:53:37 +00003451- Patch #1676823: Added create_connection() to socket.py, which may be
3452 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003453 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003454
Martin v. Löwis0af33882007-03-23 13:27:15 +00003455- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003462- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3463 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003464 directories.
3465

3467 GNOME or KDE browser, depending on whether there is a session of one
3468 of those present. Also, it tries the Windows default browser before
3469 trying Mozilla variants.

3475
Georg Brandlf66b6032007-03-14 08:27:52 +00003476- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477 AttributeError instead of an IOError when the server's response
3478 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003479
Georg Brandl3ee81df2008-05-17 18:14:43 +00003480- Patch #957650: "%var%" environment variable references are now
3481 properly expanded in ntpath.expandvars(), also "~user" home
3482 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003483
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484- Patch #1429539: pdb now correctly initializes the __main__ module
3485 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003486 correctly now.
3487
Georg Brandlbad6f192007-03-13 21:32:56 +00003488- The nonobvious commands.getstatus() function is now deprecated.

3494
Georg Brandl3ee81df2008-05-17 18:14:43 +00003495- Patch #1530482: add pydoc.render_doc() which returns the
3496 documentation for a thing instead of paging it to stdout, which
3497 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003498
Georg Brandl3ee81df2008-05-17 18:14:43 +00003499- Patch #1533909: the timeit module now accepts callables in addition

3505 parameter which can be set to False to prevent the default
3506 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003507
Georg Brandl9e6b4702007-03-13 18:15:41 +00003508- Patch #1581073: add a flag to textwrap that prevents the dropping of
3509 whitespace while wrapping.
3510
Georg Brandl92a6bae2007-03-13 17:43:32 +00003511- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003512 are set for invalid interpolation sequences that would lead to
3513 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003514

3527
Georg Brandl94fe3f52007-03-13 09:32:11 +00003528- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529 field names in its exception message if you try to write a record
3530 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003548

3556 returned string up to the first NUL character.
3557

3567
Georg Brandl3ee81df2008-05-17 18:14:43 +00003568- unittest now verifies more of its assumptions. In particular,
3569 TestCase and TestSuite subclasses (not instances) are no longer
3570 accepted in TestSuite.addTest(). This should cause no
3571 incompatibility since it never made sense with ordinary subclasses
3572 -- the failure just occurred later, with a more cumbersome
3573 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003574

3582 given a unicode argument and os.listdir() returns unicode filenames.
3583
Georg Brandl3ee81df2008-05-17 18:14:43 +00003584- Patch #1673619: setup.py identifies extension modules it doesn't

3586 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003962 time so that opening a database previously created with the DB_DUP
3963 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3964 opens. Specifically: dictionary assignment to a DB object will
3965 replace all values for a given key when the database allows
3966 duplicate values. DB users should use DB.put(k, v) when they want
3967 to store duplicates; not DB[k] = v.

3974 characters with ASCII value less than 32. Also, it correctly quotes
3975 dots only if they occur on a single line, as opposed to the previous
3976 behavior of quoting dots if they are the second character of any
3977 line.
