78 file position when calling `truncate()`. It would previously change the
79 file position to the given argument, which goes against the tradition of
80 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
81
Benjamin Peterson00b90512010-01-25 03:35:04 +000082- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

Tarek Ziadé06426fc2010-01-11 22:54:57 +0000103- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

113
Antoine Pitrou0b074572010-01-08 19:21:34 +0000114- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
115 renaming of `cPickle` to `pickle`. The warning was annoying since there's
116 no alternative to cPickle if you care about performance. Patch by Florent
117 Xicluna.
118
Antoine Pitrou8dba7272010-01-07 18:04:12 +0000119- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

126 the Distutils upload command to avoid an error when PyPI reads it.
127 This occurs on long passwords. Initial patch by JP St. Pierre.
128
Senthil Kumaran81163642009-12-20 06:32:46 +0000129- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

154
Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000155- Issue #7318: multiprocessing now uses a timeout when it fails to establish
156 a connection with another process, rather than looping endlessly. The

158 local connections.
159
Antoine Pitrouc747d3a2009-11-09 16:47:50 +0000160- Issue #7282: Fix a memory leak when an RLock was used in a thread other
161 than those started through `threading.Thread` (for example, using
162 `thread.start_new_thread()`.
163
Antoine Pitrou4fb961c2009-11-05 13:44:28 +0000164- Issue #7264: Fix a possible deadlock when deallocating thread-local objects

173 LP64 platforms (most 64-bit Linux, bsd, unix systems).
174
Gregory P. Smith6da85f92009-11-01 18:31:13 +0000175- Issue #7246 & Issue #7208: getpass now properly flushes input before
176 reading from stdin so that existing input does not confuse it and
177 lead to incorrect entry or an IOError. It also properly flushes it
178 afterwards to avoid the terminal echoing the input afterwards on
179 OSes such as Solaris.
180
Raymond Hettinger80d49b32009-11-01 08:53:21 +0000181- Issue #7244: itertools.izip_longest() no longer ignores exceptions

185 sure that they accept an int or long as the second argument. Also
186 fix buggy handling of large arguments (those with coefficient longer
187 than the current precision) in shift and rotate.
188
R. David Murray7034db32009-10-27 23:39:06 +0000189- Issue #7082: When falling back to the MIME 'name' parameter, the
190 correct place to look for it is the Content-Type header.
191
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000192- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
193 larger than emax.
194
Antoine Pitrouf3a0ff62009-10-27 17:46:09 +0000195- Issue #7205: Fix a possible deadlock when using a BZ2File object from
196 several threads at once.
197

199 is too large to fit in the current precision.
200
Matthias Kloseb9ba2bb2010-01-16 10:31:22 +0000201- Issue #1488943: difflib.Differ() doesn't always add hints for tab characters
202
Ezio Melotti05327832010-01-16 18:43:14 +0000203- Issue #5037: Proxy the __unicode__ special method to __unicode__ instead of
204 __str__.

1121What's New in Python 2.6.1
1122==========================
1123
1124*Release date: 04-Dec-2008*
1125
1126Core and Builtins
1127-----------------
1128
1129- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1130 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1131 instead of throwing a MemoryError.
1132
1133- Issue #4367: Python would segfault during compiling when the unicodedata
1134 module couldn't be imported and \N escapes were present.
1135
1136- Issue #4348: Some bytearray methods returned that didn't cause any change to
1137 the bytearray, returned the same bytearray instead of a copy.
1138
1139- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1140
1141- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1142
1143- Issue #4048: The parser module now correctly validates relative imports.
1144
1145- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1146 exec statement.
1147
1148- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1149 method does not return iterators for the 4th and 5th items.
1150
1151- Issue #4209: Enabling unicode_literals and the print_function in the same
1152 __future__ import didn't work.
1153
1154- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1155 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1156 really executed because I cannot move to such directory on win2k)
1157
1158- Issue #4069: When set.remove(element) is used with a set element, the element
1159 is temporarily replaced with an equivalent frozenset. But the eventual
1160 KeyError would always report the empty frozenset([]) as the missing key. Now
1161 it correctly refers to the initial element.
1162
1163- Fixed C99 style comments in several files. Python is now C89 compatible
1164 again.

1309-----------------
1310
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001311- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1312
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001313- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1314 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1315 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1316 ``printf`` function, whereas PyString_FromFormat has an independent
1317 implementation and uses "%zd" on all platforms for size_t values.
1318 This makes a difference on win64, where ``printf`` needs "%Id" to display
1319 64bit values.
1320
Benjamin Peterson97179b02008-09-09 20:55:01 +00001321- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1322 error.
1323
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001324- Issue #3777: long() applied to a float object now always return a long
1325 object; previously an int would be returned for small values. the __long__
1326 method is allowed to return either an int or a long, but the behaviour of
1327 float objects should not change to respect backward compatibility.
1328
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001329- Issue #3751: str.rpartition would perform a left-partition when called with
1330 a unicode argument.
1331
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001332- Issue #3683: Fix compilation when --without-threads is given.
1333
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001334- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001335 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001336 was correctly parsed but parsing of subsequent arguments failed.
1337
Vinay Sajip35e3b032008-09-01 14:33:59 +00001338- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001339 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1340 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1341 when given a tuple of classes as second argument, were looking up
1342 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1343 type object.
1344
Neal Norwitz18aa3882008-08-24 05:04:52 +00001345- Fix crashes on memory allocation failure found with failmalloc.
1346
1347- Fix memory leaks found with valgrind and update suppressions file.
1348
1349- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1350
1351- Fix problem using wrong name in decimal module reported by pychecker.
1352
Christian Heimes7d4c3172008-08-22 19:47:25 +00001353- Silenced another compiler warning about a used but not defined
1354 function 'stringlib_contains_obj'.
1355
Benjamin Peterson712ee922008-08-24 18:10:20 +00001356- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1357 ``__delslice__``.
1358
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001359- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1360 library targets in the Makefile.
1361
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001362- Issue #1204: The configure script now tests for additional libraries
1363 that may be required when linking against readline. This fixes issues
1364 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001381- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1382 silent misbehaviour when a single instance is nested in multiple
1383 with statements, or when the methods are invoked in the wrong order.
1384
Vinay Sajip844f7412008-09-09 13:42:08 +00001385- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1386
Nick Coghland2e09382008-09-11 12:11:06 +00001387- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001388 return a list or None rather than a custom object.

1414 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1415 for catch_warnings() also led to an improvement in the raising of a
1416 DeprecationWarning related to warnings.warn_explicit().
1417
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001418- The deprecation warnings for the old camelCase threading API were removed.

1437
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001438- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001479What's New in Python 2.6 beta 3?
1480================================
1481
Barry Warsaw07a4a382008-08-21 01:15:08 +00001482*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001483
1484Core and Builtins
1485-----------------
1486
Guido van Rossumf8402962008-08-20 15:01:50 +00001487- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1488 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1489 extensions do not automatically benefit from the class attribute
1490 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1491 to their tp_flags field if they care. This is a backwards
1492 compatibility feature; in 3.0, all types will use the cache by
1493 default.
1494
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001495- Keyword arguments can now follow starred arguments. (``f(a, *args,
1496 keyword=23)`` is now valid syntax.)
1497
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001498- ctypes function pointers that are COM methods have a boolean True
1499 value again.
1500
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001501- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1502 by denying s# to parse objects that have a releasebuffer procedure,
1503 and introducing s*.
1504
Georg Brandl1e13ea92008-08-11 09:07:59 +00001505- Issue #3537: Fix an assertion failure when an empty but presized dict
1506 object was stored in the freelist.
1507
Mark Dickinsonb6467572008-08-04 21:30:09 +00001508- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1509 ValueError consistently across platforms.
1510
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001511- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1512 (64bit Unix, for example), unichr() would truncate its argument and return
1513 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1514
Neal Norwitze7d8be82008-07-31 17:17:14 +00001515- Apply security patches from Apple.
1516
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001517- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1518 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1519
Antoine Pitrou92f82162008-07-25 22:22:08 +00001520- Issue #1819: function calls with several named parameters are now on
1521 average 35% faster (as measured by pybench).
1522
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001523- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1524 the python debugger steps into a class statement: the free variables (local
1525 variables defined in an outer scope) would be deleted from the outer scope.
1526
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001527- Issue #2620: Overflow checking when allocating or reallocating memory
1528 was not always being done properly in some python types and extension
1529 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1530 all been updated to perform better checks and places in the code that
1531 would previously leak memory on the error path when such an allocation
1532 failed have been fixed.
1533
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001534Library
1535-------
1536

1538
Benjamin Petersone977ad42008-08-20 01:42:01 +00001539- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1540 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1541
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001542- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1543 version reported by these tools does not necessarily follow the python
1544 version numbering scheme, so the module is less strict when parsing it.
1545
Nick Coghlanf70385a2008-08-18 12:42:46 +00001546- Issue #2235: Added Py3k warnings for types which will become unhashable
1547 under the stricter __hash__ inheritance rules in 3.0. Several types
1548 which did not meet the rules for hash invariants and were already
1549 unhashable in 3.0 have now been explicitly flagged as unhashable in
1550 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1551 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1552
Brett Cannon88f801d2008-08-18 00:46:22 +00001553- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1554 imported into the module but exposed as part of the module's API.
1555
Brett Cannon7b96f072008-08-18 00:41:11 +00001556- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1557
Brett Cannon46225e72008-08-18 00:36:52 +00001558- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001560- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1561
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001562- Issue #3575: Incremental decoder's decode function now takes bytearray
1563 by using 's*' instead of 't#'.
1564
Jesus Cea585ad8a2009-07-02 15:37:21 +00001565- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001566 fails unicode conversion on 2nd parameter. (windows only)
1567
Facundo Batista94f243a2008-08-17 03:38:39 +00001568- Issue 2464. urllib2 now supports a malformation in the URL received
1569 in a redirect.
1570
Brett Cannonabe423e2008-08-16 21:47:07 +00001571- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001572 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001573
Facundo Batistaeb90b782008-08-16 14:44:07 +00001574- Issue #2776: fixed small issue when handling an URL with double slash
1575 after a 302 response in the case of not going through a proxy.
1576
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001577- Issue #2676: in the email package, content-type parsing was hanging on
1578 pathological input because of quadratic or exponential behaviour of a
1579 regular expression.
1580
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001581- Issue #3476: binary buffered reading through the new "io" library is now
1582 thread-safe.
1583
Brett Cannonbf3157b2008-08-14 05:00:03 +00001584- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1585 since mimetools itself is deprecated. Because modules are cached, all
1586 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1587
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001588- Issue #3134: shutil referenced undefined WindowsError symbol.

Antoine Pitroude781a42008-08-09 12:43:23 +00001622 asking for a specific length. This problem only affected files opened

1666
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001667- Issue #643841: The language reference now provides more detailed

1679-----------------
1680
Georg Brandl3e483f62008-07-16 22:57:41 +00001681- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1682 its methods now allow for items objects that can be converted to
1683 an integer using operator.index().
1684
Mark Dickinson64b7e502008-07-16 09:40:03 +00001685- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1686 produced a ValueError instead of giving the correct float.
1687
Eric Smitha5fa5a22008-07-16 00:11:49 +00001688- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1689 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1690
Mark Dickinson7103aa42008-07-15 19:08:33 +00001691- Issue #3008: the float type has a new instance method 'float.hex'
1692 and a new class method 'float.fromhex' to convert floating-point
1693 numbers to and from hexadecimal strings, respectively.
1694
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001695- Issue #2235: __hash__ is once again inherited by default. To allow
1696 collections.Hashable to remain meaningful in the presence of the
1697 default hash implementation (object.__hash__), it is now possible
1698 to explicit block inheritance of hash by setting __hash__=None at
1699 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1700 level.
1701
Nick Coghlanb028f502008-07-13 14:52:36 +00001702- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1703 the parent module cannot be found while performing an absolute import.
1704 This means that an incorrectly defined __package__ attribute will
1705 now only prevent relative imports in that module rather than causing
1706 all imports from that module to fail.
1707
Nick Coghlan14ff9942008-07-08 14:21:42 +00001708- Issue #2517: Allow unicode messages in Exceptions again by correctly

1717 threading.local: the first member set by a thread could be saved in
1718 another thread's dictionary.
1719
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001720- Issue #3004: Minor change to slice.indices(): the start and stop
1721 arguments are now treated identically, making the behaviour easier
1722 to describe and understand. For example, slice(None, -10,
1723 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1724 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1725 10, -1).
1726
Georg Brandl278fc502008-07-19 12:46:12 +00001727- Issue #3219: Calling a function with repeated keyword arguments,
1728 f(a=2, a=23), would not cause a syntax error. This was a regression
1729 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001730
Georg Brandl278fc502008-07-19 12:46:12 +00001731- Issue #2862: Make int and float freelist management consistent with
1732 other freelists. Changes their CompactFreeList apis into

1739 api functions without holding the GIL, which could lead to a fatal
1740 error when they failed.
1741
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001742- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001767- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1768 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001769 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001770 content-length. The problem had been corrected in the 2.4 branch, but never
1771 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001786- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002158 environment to control the '-arch' flags that are used to build
2159 an extension. This was added for compatibility with Apple's build
2160 of Python.
2161
2162- The bundled OSX-specific copy of libbffi is now in sync with the version
2163 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2164
Georg Brandl25c34082008-08-18 23:09:49 +00002165- The threading module gained aliases for names that will be removed in the
2166 3.x series.

2174
Brett Cannonb61d8012008-05-11 23:39:04 +00002175- ``Lib/lib-old`` is now added to sys.path.
2176
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002177- On MacOS X it is now possible to install the framework in 64-bit
2178 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002179 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002180
2181 This is controlled by the configure argument ``--with-universal-archs``:
2182
2183 - ``--with-universal-archs=all``: install 4-way universal
2184
2185 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2186
2187 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2188
2189 This option should be used in combination with ``--enable-universalsdk=``.
2190
2191 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

2199- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002200
2201- The PyString functions have been renamed to PyBytes. A batch of
2202 defines were added so that the linker still sees the original
2203 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002241- Issue #1631171: Re-implement the 'warnings' module in C (the
2242 original Python code has been kept as backup). This will allow for
2243 using the 'warning's machinery in such places as the parser where
2244 use of pure Python code is not possible. Both the ``showarning()``
2245 and ``formatwarning()`` gain an optional 'line' argument which is
2246 not called by default for backwards-compatibility reasons. Setting
2247 ``warnings.showwarning()`` to an implementation that lacks support
2248 for the ``line`` argument will raise a DeprecationWarning.

2272
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002273- The getpass module has been improved on Unix. It now uses /dev/tty
2274 by default and uses stderr instead of stdout. A GetPassWarning is
2275 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002276

Georg Brandl3ee81df2008-05-17 18:14:43 +00002290- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002291 extension modules between 32 and 64 bit platforms. See the distutls

2296 file.close() is called while an object is in use by another thread
2297 an IOError exception will be raised and the file will not be closed.
2298
Thomas Hellerf7906482008-04-04 19:43:25 +00002299- The bundled libffi copy is now in sync with the recently released

2304 so the controlled environment will more closely mirror the typical
2305 script environment. This supports setup.py scripts that refer to
2306 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002311- Issue #2550: The approach used by client/server code for obtaining
2312 ports to listen on in network-oriented tests has been refined in an
2313 effort to facilitate running multiple instances of the entire
2314 regression test suite in parallel without issue.
2315 test_support.bind_port() has been fixed such that it will always
2316 return a unique port -- which wasn't always the case with the
2317 previous implementation, especially if socket options had been set
2318 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2319 new implementation of bind_port() will actually raise an exception
2320 if it is passed an AF_INET/SOCK_STREAM socket with either the
2321 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2322 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2323 the socket it's been passed. This currently only applies to
2324 Windows. This option prevents any other sockets from binding to the
2325 host/port we've bound to, thus removing the possibility of the
2326 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2327 when a second SOCK_STREAM socket binds and accepts to a host/port
2328 that's already been bound by another socket. The optional preferred
2329 port parameter to bind_port() has been removed. Under no
2330 circumstances should tests be hard coding ports!
2331
2332 test_support.find_unused_port() has also been introduced, which will
2333 pass a temporary socket object to bind_port() in order to obtain an
2334 unused port. The temporary socket object is then closed and
2335 deleted, and the port is returned. This method should only be used
2336 for obtaining an unused port in order to pass to an external program
2337 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2338 a parameter to a server-oriented class that doesn't give you direct
2339 access to the underlying socket used.
2340
2341 Finally, test_support.HOST has been introduced, which should be used
2342 for the host argument of any relevant socket calls (i.e. bind and
2343 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002344
2345 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002346 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002347 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2348 test_asynchat and test_socket_ssl.
2349
Georg Brandl3ee81df2008-05-17 18:14:43 +00002350 It is now possible for multiple instances of the regression test
2351 suite to run in parallel without issue.

2618-----------------
2619
Fred Drakea8ee94b2008-03-01 02:45:07 +00002620- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002621 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002626
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002627- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002628 issue 215555 for a discussion.
2629
Eric Smitha73fbe72008-02-23 03:09:44 +00002630- Added the future_builtins module, which contains hex() and oct().
2631 These are the PEP 3127 version of these functions, designed to be
2632 compatible with the hex() and oct() builtins from Python 3.0. They
2633 differ slightly in their output formats from the existing, unchanged
2634 Python 2.6 builtins. The expected usage of the future_builtins
2635 module is:
2636 from future_builtins import hex, oct
2637
Eric Smith7ef40bf2008-02-20 23:34:22 +00002638- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2639 exponents for exponents with absolute value < 100. Follows C99
2640 standard. This is a change on Windows, which would use 3 digits.
2641 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2642 so that any alterations it does to the resulting string will be
2643 available in stringlib/formatter.h (for float.__format__).
2644
Eric Smith5a3c1352008-02-19 13:21:56 +00002645- Implemented PEP 3101, Advanced String Formatting. This adds a new
2646 builtin format(); a format() method for str and unicode; a
2647 __format__() method to object, str, unicode, int, long, float, and
2648 datetime; the class string.Formatter; and the C API
2649 PyObject_Format().
2650
Georg Brandl3ee81df2008-05-17 18:14:43 +00002651- Fixed several potential crashes, all caused by specially crafted
2652 __del__ methods exploiting objects in temporarily inconsistent
2653 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002654
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002655- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002656 prevent a possible crash: an Abstract Base Class would try to access
2657 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002658

2660 real or imaginary part.

2663 in order to allow pymalloc to free more arenas. Python may give back
2664 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002665
Georg Brandl3ee81df2008-05-17 18:14:43 +00002666- Issue #2045: Fix an infinite recursion triggered when printing a
2667 subclass of collections.defaultdict, if its default_factory is set
2668 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002669
Christian Heimesf75dbef2008-02-08 00:11:31 +00002670- Fixed a minor memory leak in dictobject.c. The content of the free
2671 list was not freed on interpreter shutdown.
2672
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Limit free list of method and builtin function objects to 256
2674 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002675
Georg Brandl3ee81df2008-05-17 18:14:43 +00002676- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2677 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002678 to compact the internal free lists of pre-allocted ints and floats.
2679
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2681 calls. Python expected the return type int but the fork familie
2682 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002683
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2685 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2688 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002689
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2691 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002692
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2694 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002695
Georg Brandl3ee81df2008-05-17 18:14:43 +00002696- Patch #1473257: generator objects gain a gi_code attribute. This is
2697 the same object as the func_code attribute of the function that
2698 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002699
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Issue #1920: "while 0" statements were completely removed by the
2701 compiler, even in the presence of an "else" clause, which is
2702 supposed to be run when the condition is false. Now the compiler
2703 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002704
Guido van Rossumeead05f2008-01-24 18:21:02 +00002705- A few crashers fixed: weakref_in_del.py (issue #1377858);
2706 loosing_dict_ref.py (issue #1303614, test67.py);
2707 borrowed_ref_[34].py (not in tracker).
2708
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002709- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002710 suppressed while an extension is loaded by calling SetErrorMode in
2711 dynload_win.c. The error is still reported properly.
2712
Georg Brandl3ee81df2008-05-17 18:14:43 +00002713- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002714 several extension methods and modules do not work without unicode
2715 support.
2716
Georg Brandl26543b12008-01-21 18:36:51 +00002717- Issue #1882: when compiling code from a string, encoding cookies in the
2718 second line of code were not always recognized correctly.
2719
Georg Brandl14404b62008-01-19 19:27:05 +00002720- Issue #1679: "0x" was taken as a valid integer literal.
2721
Georg Brandl6caad7d2008-01-26 14:19:22 +00002722- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002723 added.
2724
Christian Heimesc94e2b52008-01-14 04:13:37 +00002725- sys.float_info / PyFloat_GetInfo: The floating point information
2726 object was converted from a dict to a specialized structseq object.
2727
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Patch #1816: Added sys.flags structseq. It exposes the status of
2729 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002730
Georg Brandl3ee81df2008-05-17 18:14:43 +00002731- Objects/structseq.c: Implemented new structseq representation. The
2732 patch makes structseqs (e.g. the return value of os.stat) more
2733 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002734
Georg Brandl3ee81df2008-05-17 18:14:43 +00002735- Patch #1700288: added a type attribute cache that caches method
2736 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002737
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002738- Bug #1776: __import__() no longer accepts filenames on any platform.
2739 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002740
Georg Brandlaed6c662008-01-07 17:25:53 +00002741- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2742
Georg Brandl3ee81df2008-05-17 18:14:43 +00002743- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2744 envvar and sys.dont_write_bytecode attribute. All these can be set
2745 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002746
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747- Improve some exception messages when Windows fails to load an
2748 extension module. Now we get for example '%1 is not a valid Win32
2749 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002750

Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2754 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002755
Christian Heimes0a8143f2007-12-18 23:22:54 +00002756- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002757 and INF. float("nan"), float("inf") and float("-inf") now work on
2758 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Compiler now generates simpler and faster code for dictionary
2761 literals. The oparg for BUILD_MAP now indicates an estimated
2762 dictionary size. There is a new opcode, STORE_MAP, for adding
2763 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002764

Georg Brandl3ee81df2008-05-17 18:14:43 +00002792- Patch #1739468: Directories and zipfiles containing a __main__.py
2793 file can now be directly executed by passing their name to the
2794 interpreter. The directory/zipfile is automatically inserted as the
2795 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002796
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Issue #1265: Fix a problem with sys.settrace, if the tracing
2798 function uses a generator expression when at the same time the
2799 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002800
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002801- sets and frozensets now have an isdisjoint() method.
2802
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002803- optimize the performance of builtin.sum().
2804
Neal Norwitz44f326e2007-10-05 05:29:17 +00002805- Fix warnings found by the new version of the Coverity checker.
2806
Georg Brandl3ee81df2008-05-17 18:14:43 +00002807- The enumerate() builtin function is no longer bounded to sequences
2808 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2809 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002810
Georg Brandl3ee81df2008-05-17 18:14:43 +00002811- Issue #1686386: Tuple's tp_repr did not take into account the
2812 possibility of having a self-referential tuple, which is possible
2813 from C code. Nor did object's tp_str consider that a type's tp_str
2814 could do something that could lead to an inifinite recursion.
2815 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2816 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002817
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Issue #1164: It was possible to trigger deadlock when using the
2819 'print' statement to write to a file since the GIL was not released
2820 as needed. Now PyObject_Print() does the right thing along with
2821 various tp_print implementations of the built-in types and those in
2822 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Issue #1147: Exceptions were directly allowing string exceptions in
2825 their throw() method even though string exceptions no longer
2826 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002827
Georg Brandl3ee81df2008-05-17 18:14:43 +00002828- Issue #1096: Prevent a segfault from getting the repr of a very
2829 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002830
Brett Cannon1e534b52007-09-07 04:18:30 +00002831- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 PyObject_Call() never calling back out to Python code to trigger
2833 recursion depth updates/checks. Required the creation of a static
2834 RuntimeError instance in case normalizing an exception put the
2835 recursion check value past its limit. Fixes crashers
2836 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002851- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002852 __*__ attributes. (Some already existed, e.g., __doc__ and
2853 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002854
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002855- Add -3 option to the interpreter to warn about features that are
2856 deprecated and will be changed/removed in Python 3.0.
2857
Georg Brandl2134e752007-05-21 20:34:16 +00002858- Patch #1686487: you can now pass any mapping after '**' in function
2859 calls.
2860
Collin Winter62903052007-05-18 23:11:24 +00002861- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862 "except E as target:". This is to provide forwards compatibility
2863 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002864
Brett Cannon229cee22007-05-05 01:34:02 +00002865- Deprecate BaseException.message as per PEP 352.
2866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002868 inherited from a builtin base.
2869
Vinay Sajip8549ce32007-05-06 17:53:37 +00002870- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002871 setting a plain string, ie don't expand to single letter identifiers.
2872
Raymond Hettinger13936692007-04-11 18:40:58 +00002873- Request #1191699: Slices can now be pickled.
2874
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002875- Request #1193128: str.translate() now allows a None argument for
2876 translations that only remove characters without re-mapping the
2877 remaining characters.
2878
Georg Brandl5cb76c12007-03-21 09:00:39 +00002879- Patch #1682205: a TypeError while unpacking an iterable is no longer
2880 masked by a generic one with the message "unpack non-sequence".
2881
Neal Norwitzaa754b72007-03-21 06:39:48 +00002882- Remove unused file Python/fmod.c.
2883
Guido van Rossum143b5642007-03-23 04:58:42 +00002884- Bug #1683368: The object.__init__() and object.__new__() methods are
2885 now stricter in rejecting excess arguments. The only time when
2886 either allows excess arguments is when it is not overridden and the
2887 other one is. For backwards compatibility, when both are
2888 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002889 warning later). Also, type.__init__() insists on the same signature
2890 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2893 object to complex using its __complex__() method before falling back
2894 to the __float__() method. Therefore, the functions in the cmath
2895 module now can operate on objects that define a __complex__()
2896 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002897
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- Patch #1623563: allow __class__ assignment for classes with
2899 __slots__. The old and the new class are still required to have the
2900 same slot names.

2913
Georg Brandl7b9c5552007-03-12 14:30:05 +00002914- Bug #1678647: write a newline after printing an exception in any
2915 case, even when converting the value to a string failed.

Georg Brandl871f1bc2007-03-12 13:17:36 +00002917- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918 its argument, if it exists. If not, it will work like before. This
2919 allows customizing the output of dir() in the presence of a
2920 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002932- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl3ee81df2008-05-17 18:14:43 +00003444 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003485 AttributeError instead of an IOError when the server's response

Georg Brandl92a6bae2007-03-13 17:43:32 +00003519- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003520 are set for invalid interpolation sequences that would lead to

3577 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003970 time so that opening a database previously created with the DB_DUP
3971 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3972 opens. Specifically: dictionary assignment to a DB object will
3973 replace all values for a given key when the database allows
3974 duplicate values. DB users should use DB.put(k, v) when they want
3975 to store duplicates; not DB[k] = v.

3982 characters with ASCII value less than 32. Also, it correctly quotes
3983 dots only if they occur on a single line, as opposed to the previous
3984 behavior of quoting dots if they are the second character of any
3985 line.
