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 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

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

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.

199 is too large to fit in the current precision.

753 object also got a new readonly attribute ``closefd``.
754
Georg Brandlfa71a902008-12-05 09:08:28 +0000755- Issue #3689: The list reversed iterator now supports __length_hint__

1126What's New in Python 2.6.1
1127==========================
1128
1129*Release date: 04-Dec-2008*
1130
1131Core and Builtins
1132-----------------
1133
1134- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1135 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1136 instead of throwing a MemoryError.
1137
1138- Issue #4367: Python would segfault during compiling when the unicodedata
1139 module couldn't be imported and \N escapes were present.
1140
1141- Issue #4348: Some bytearray methods returned that didn't cause any change to
1142 the bytearray, returned the same bytearray instead of a copy.
1143
1144- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1145
1146- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1147
1148- Issue #4048: The parser module now correctly validates relative imports.
1149
1150- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1151 exec statement.
1152
1153- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1154 method does not return iterators for the 4th and 5th items.
1155
1156- Issue #4209: Enabling unicode_literals and the print_function in the same
1157 __future__ import didn't work.
1158
1159- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1160 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1161 really executed because I cannot move to such directory on win2k)
1162
1163- Issue #4069: When set.remove(element) is used with a set element, the element
1164 is temporarily replaced with an equivalent frozenset. But the eventual
1165 KeyError would always report the empty frozenset([]) as the missing key. Now
1166 it correctly refers to the initial element.
1167
1168- Fixed C99 style comments in several files. Python is now C89 compatible
1169 again.

1296- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1297 AttributeError instead of RuntimeError, depending in which C API call
1298 exactly the recursion limit is exceeded. Consequently, both exception types
1299 are caught and silenced.

1314-----------------
1315
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001316- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1317
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001318- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1319 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1320 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1321 ``printf`` function, whereas PyString_FromFormat has an independent
1322 implementation and uses "%zd" on all platforms for size_t values.
1323 This makes a difference on win64, where ``printf`` needs "%Id" to display
1324 64bit values.
1325
Benjamin Peterson97179b02008-09-09 20:55:01 +00001326- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1327 error.
1328
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001329- Issue #3777: long() applied to a float object now always return a long
1330 object; previously an int would be returned for small values. the __long__
1331 method is allowed to return either an int or a long, but the behaviour of
1332 float objects should not change to respect backward compatibility.
1333
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001334- Issue #3751: str.rpartition would perform a left-partition when called with
1335 a unicode argument.
1336
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001337- Issue #3683: Fix compilation when --without-threads is given.
1338
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001339- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001340 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001341 was correctly parsed but parsing of subsequent arguments failed.
1342
Vinay Sajip35e3b032008-09-01 14:33:59 +00001343- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001344 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1345 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1346 when given a tuple of classes as second argument, were looking up
1347 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1348 type object.
1349
Neal Norwitz18aa3882008-08-24 05:04:52 +00001350- Fix crashes on memory allocation failure found with failmalloc.
1351
1352- Fix memory leaks found with valgrind and update suppressions file.
1353
1354- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1355
1356- Fix problem using wrong name in decimal module reported by pychecker.
1357
Christian Heimes7d4c3172008-08-22 19:47:25 +00001358- Silenced another compiler warning about a used but not defined
1359 function 'stringlib_contains_obj'.

1362 ``__delslice__``.
1363
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001364- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1365 library targets in the Makefile.
1366
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001367- Issue #1204: The configure script now tests for additional libraries
1368 that may be required when linking against readline. This fixes issues
1369 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001386- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1387 silent misbehaviour when a single instance is nested in multiple
1388 with statements, or when the methods are invoked in the wrong order.
1389
Vinay Sajip844f7412008-09-09 13:42:08 +00001390- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.

1419 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1420 for catch_warnings() also led to an improvement in the raising of a
1421 DeprecationWarning related to warnings.warn_explicit().
1422
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001423- The deprecation warnings for the old camelCase threading API were removed.

1442
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001443- Issue #2975: When compiling several extension modules with Visual Studio 2008

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001484What's New in Python 2.6 beta 3?
1485================================
1486
Barry Warsaw07a4a382008-08-21 01:15:08 +00001487*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001488
1489Core and Builtins
1490-----------------
1491
Guido van Rossumf8402962008-08-20 15:01:50 +00001492- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1493 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1494 extensions do not automatically benefit from the class attribute
1495 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1496 to their tp_flags field if they care. This is a backwards
1497 compatibility feature; in 3.0, all types will use the cache by
1498 default.
1499
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001500- Keyword arguments can now follow starred arguments. (``f(a, *args,
1501 keyword=23)`` is now valid syntax.)
1502
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001503- ctypes function pointers that are COM methods have a boolean True
1504 value again.
1505
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001506- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1507 by denying s# to parse objects that have a releasebuffer procedure,
1508 and introducing s*.
1509
Georg Brandl1e13ea92008-08-11 09:07:59 +00001510- Issue #3537: Fix an assertion failure when an empty but presized dict
1511 object was stored in the freelist.
1512
Mark Dickinsonb6467572008-08-04 21:30:09 +00001513- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1514 ValueError consistently across platforms.
1515
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001516- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1517 (64bit Unix, for example), unichr() would truncate its argument and return
1518 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1519
Neal Norwitze7d8be82008-07-31 17:17:14 +00001520- Apply security patches from Apple.
1521
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001522- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1523 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1524
Antoine Pitrou92f82162008-07-25 22:22:08 +00001525- Issue #1819: function calls with several named parameters are now on
1526 average 35% faster (as measured by pybench).
1527
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001528- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1529 the python debugger steps into a class statement: the free variables (local
1530 variables defined in an outer scope) would be deleted from the outer scope.
1531
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001532- Issue #2620: Overflow checking when allocating or reallocating memory
1533 was not always being done properly in some python types and extension
1534 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1535 all been updated to perform better checks and places in the code that
1536 would previously leak memory on the error path when such an allocation
1537 failed have been fixed.
1538

1543
Benjamin Petersone977ad42008-08-20 01:42:01 +00001544- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1545 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1546
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001547- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1548 version reported by these tools does not necessarily follow the python
1549 version numbering scheme, so the module is less strict when parsing it.
1550
Nick Coghlanf70385a2008-08-18 12:42:46 +00001551- Issue #2235: Added Py3k warnings for types which will become unhashable
1552 under the stricter __hash__ inheritance rules in 3.0. Several types
1553 which did not meet the rules for hash invariants and were already
1554 unhashable in 3.0 have now been explicitly flagged as unhashable in
1555 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1556 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1557
Brett Cannon88f801d2008-08-18 00:46:22 +00001558- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1559 imported into the module but exposed as part of the module's API.
1560
Brett Cannon7b96f072008-08-18 00:41:11 +00001561- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1562
Brett Cannon46225e72008-08-18 00:36:52 +00001563- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001565- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1566
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001567- Issue #3575: Incremental decoder's decode function now takes bytearray
1568 by using 's*' instead of 't#'.
1569
Jesus Cea585ad8a2009-07-02 15:37:21 +00001570- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001571 fails unicode conversion on 2nd parameter. (windows only)
1572
Facundo Batista94f243a2008-08-17 03:38:39 +00001573- Issue 2464. urllib2 now supports a malformation in the URL received
1574 in a redirect.
1575
Brett Cannonabe423e2008-08-16 21:47:07 +00001576- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001577 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001578
Facundo Batistaeb90b782008-08-16 14:44:07 +00001579- Issue #2776: fixed small issue when handling an URL with double slash
1580 after a 302 response in the case of not going through a proxy.
1581
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001582- Issue #2676: in the email package, content-type parsing was hanging on
1583 pathological input because of quadratic or exponential behaviour of a
1584 regular expression.
1585
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001586- Issue #3476: binary buffered reading through the new "io" library is now
1587 thread-safe.
1588
Brett Cannonbf3157b2008-08-14 05:00:03 +00001589- Silence the DeprecationWarning of rfc822 when it is imported by mimetools

Antoine Pitroude781a42008-08-09 12:43:23 +00001627 asking for a specific length. This problem only affected files opened

1671
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001672- Issue #643841: The language reference now provides more detailed

1679================================
1680
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001681*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001683Core and Builtins
1684-----------------
1685
Georg Brandl3e483f62008-07-16 22:57:41 +00001686- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1687 its methods now allow for items objects that can be converted to
1688 an integer using operator.index().
1689
Mark Dickinson64b7e502008-07-16 09:40:03 +00001690- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1691 produced a ValueError instead of giving the correct float.
1692
Eric Smitha5fa5a22008-07-16 00:11:49 +00001693- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1694 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1695
Mark Dickinson7103aa42008-07-15 19:08:33 +00001696- Issue #3008: the float type has a new instance method 'float.hex'
1697 and a new class method 'float.fromhex' to convert floating-point
1698 numbers to and from hexadecimal strings, respectively.
1699
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001700- Issue #2235: __hash__ is once again inherited by default. To allow
1701 collections.Hashable to remain meaningful in the presence of the
1702 default hash implementation (object.__hash__), it is now possible
1703 to explicit block inheritance of hash by setting __hash__=None at
1704 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1705 level.
1706
Nick Coghlanb028f502008-07-13 14:52:36 +00001707- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1708 the parent module cannot be found while performing an absolute import.
1709 This means that an incorrectly defined __package__ attribute will
1710 now only prevent relative imports in that module rather than causing
1711 all imports from that module to fail.
1712
Nick Coghlan14ff9942008-07-08 14:21:42 +00001713- Issue #2517: Allow unicode messages in Exceptions again by correctly
1714 bypassing the instance dictionary when looking up __unicode__ on
1715 new-style classes.
1716
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001717- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1718 set to a custom object whose write() method happens to install
1719 another file in sys.stdout.
1720
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001721- Issue #3088: Corrected a race condition in classes derived from
1722 threading.local: the first member set by a thread could be saved in
1723 another thread's dictionary.
1724
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001725- Issue #3004: Minor change to slice.indices(): the start and stop
1726 arguments are now treated identically, making the behaviour easier
1727 to describe and understand. For example, slice(None, -10,
1728 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1729 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1730 10, -1).
1731
Georg Brandl278fc502008-07-19 12:46:12 +00001732- Issue #3219: Calling a function with repeated keyword arguments,
1733 f(a=2, a=23), would not cause a syntax error. This was a regression
1734 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001735
Georg Brandl278fc502008-07-19 12:46:12 +00001736- Issue #2862: Make int and float freelist management consistent with
1737 other freelists. Changes their CompactFreeList apis into
1738 ClearFreeList apis and calls them via gc.collect().

1744 api functions without holding the GIL, which could lead to a fatal
1745 error when they failed.
1746
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001747- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001772- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1773 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001774 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001775 content-length. The problem had been corrected in the 2.4 branch, but never
1776 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001791- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1793
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001794- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Benjamin Peterson23681932008-05-12 21:42:13 +00002161
Vinay Sajip9828b7e2008-06-17 11:04:02 +00002162- Library: on MacOS X you can now set ``ARCHFLAGS`` in the shell
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002163 environment to control the '-arch' flags that are used to build
2164 an extension. This was added for compatibility with Apple's build
2165 of Python.
2166
2167- The bundled OSX-specific copy of libbffi is now in sync with the version
2168 shipped with PyObjC 2.0 and includes support for x86_64 and ppc64 platforms.
2169
Georg Brandl25c34082008-08-18 23:09:49 +00002170- The threading module gained aliases for names that will be removed in the
2171 3.x series.

2179
Brett Cannonb61d8012008-05-11 23:39:04 +00002180- ``Lib/lib-old`` is now added to sys.path.
2181
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002182- On MacOS X it is now possible to install the framework in 64-bit
2183 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002184 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002185
2186 This is controlled by the configure argument ``--with-universal-archs``:
2187
2188 - ``--with-universal-archs=all``: install 4-way universal
2189
2190 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2191
2192 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2193
2194 This option should be used in combination with ``--enable-universalsdk=``.
2195
2196 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002205
2206- The PyString functions have been renamed to PyBytes. A batch of
2207 defines were added so that the linker still sees the original
2208 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002246- Issue #1631171: Re-implement the 'warnings' module in C (the
2247 original Python code has been kept as backup). This will allow for
2248 using the 'warning's machinery in such places as the parser where
2249 use of pure Python code is not possible. Both the ``showarning()``
2250 and ``formatwarning()`` gain an optional 'line' argument which is
2251 not called by default for backwards-compatibility reasons. Setting
2252 ``warnings.showwarning()`` to an implementation that lacks support
2253 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002278- The getpass module has been improved on Unix. It now uses /dev/tty
2279 by default and uses stderr instead of stdout. A GetPassWarning is
2280 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002295- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002296 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002316- Issue #2550: The approach used by client/server code for obtaining
2317 ports to listen on in network-oriented tests has been refined in an
2318 effort to facilitate running multiple instances of the entire
2319 regression test suite in parallel without issue.
2320 test_support.bind_port() has been fixed such that it will always
2321 return a unique port -- which wasn't always the case with the
2322 previous implementation, especially if socket options had been set
2323 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2324 new implementation of bind_port() will actually raise an exception
2325 if it is passed an AF_INET/SOCK_STREAM socket with either the
2326 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2327 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2328 the socket it's been passed. This currently only applies to
2329 Windows. This option prevents any other sockets from binding to the
2330 host/port we've bound to, thus removing the possibility of the
2331 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2332 when a second SOCK_STREAM socket binds and accepts to a host/port
2333 that's already been bound by another socket. The optional preferred
2334 port parameter to bind_port() has been removed. Under no
2335 circumstances should tests be hard coding ports!
2336
2337 test_support.find_unused_port() has also been introduced, which will
2338 pass a temporary socket object to bind_port() in order to obtain an
2339 unused port. The temporary socket object is then closed and
2340 deleted, and the port is returned. This method should only be used
2341 for obtaining an unused port in order to pass to an external program
2342 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2343 a parameter to a server-oriented class that doesn't give you direct
2344 access to the underlying socket used.
2345
2346 Finally, test_support.HOST has been introduced, which should be used
2347 for the host argument of any relevant socket calls (i.e. bind and
2348 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002349
2350 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002351 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002352 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2353 test_asynchat and test_socket_ssl.
2354
Georg Brandl3ee81df2008-05-17 18:14:43 +00002355 It is now possible for multiple instances of the regression test
2356 suite to run in parallel without issue.

2622Core and builtins
2623-----------------
2624
Fred Drakea8ee94b2008-03-01 02:45:07 +00002625- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002626 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002631
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002632- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002633 issue 215555 for a discussion.
2634
Eric Smitha73fbe72008-02-23 03:09:44 +00002635- Added the future_builtins module, which contains hex() and oct().
2636 These are the PEP 3127 version of these functions, designed to be
2637 compatible with the hex() and oct() builtins from Python 3.0. They
2638 differ slightly in their output formats from the existing, unchanged
2639 Python 2.6 builtins. The expected usage of the future_builtins
2640 module is:
2641 from future_builtins import hex, oct
2642
Eric Smith7ef40bf2008-02-20 23:34:22 +00002643- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2644 exponents for exponents with absolute value < 100. Follows C99
2645 standard. This is a change on Windows, which would use 3 digits.
2646 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2647 so that any alterations it does to the resulting string will be
2648 available in stringlib/formatter.h (for float.__format__).
2649
Eric Smith5a3c1352008-02-19 13:21:56 +00002650- Implemented PEP 3101, Advanced String Formatting. This adds a new
2651 builtin format(); a format() method for str and unicode; a
2652 __format__() method to object, str, unicode, int, long, float, and
2653 datetime; the class string.Formatter; and the C API
2654 PyObject_Format().
2655
Georg Brandl3ee81df2008-05-17 18:14:43 +00002656- Fixed several potential crashes, all caused by specially crafted
2657 __del__ methods exploiting objects in temporarily inconsistent
2658 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002659
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002660- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002661 prevent a possible crash: an Abstract Base Class would try to access
2662 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002663

2665 real or imaginary part.

2668 in order to allow pymalloc to free more arenas. Python may give back
2669 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002670
Georg Brandl3ee81df2008-05-17 18:14:43 +00002671- Issue #2045: Fix an infinite recursion triggered when printing a
2672 subclass of collections.defaultdict, if its default_factory is set
2673 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002674
Christian Heimesf75dbef2008-02-08 00:11:31 +00002675- Fixed a minor memory leak in dictobject.c. The content of the free
2676 list was not freed on interpreter shutdown.
2677
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Limit free list of method and builtin function objects to 256
2679 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002680
Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2682 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002683 to compact the internal free lists of pre-allocted ints and floats.
2684
Georg Brandl3ee81df2008-05-17 18:14:43 +00002685- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2686 calls. Python expected the return type int but the fork familie
2687 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2690 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002691
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2693 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2696 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002697
Georg Brandl3ee81df2008-05-17 18:14:43 +00002698- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2699 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Patch #1473257: generator objects gain a gi_code attribute. This is
2702 the same object as the func_code attribute of the function that
2703 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002704
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705- Issue #1920: "while 0" statements were completely removed by the
2706 compiler, even in the presence of an "else" clause, which is
2707 supposed to be run when the condition is false. Now the compiler
2708 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002709
Guido van Rossumeead05f2008-01-24 18:21:02 +00002710- A few crashers fixed: weakref_in_del.py (issue #1377858);
2711 loosing_dict_ref.py (issue #1303614, test67.py);
2712 borrowed_ref_[34].py (not in tracker).
2713
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002714- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002715 suppressed while an extension is loaded by calling SetErrorMode in
2716 dynload_win.c. The error is still reported properly.
2717
Georg Brandl3ee81df2008-05-17 18:14:43 +00002718- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002719 several extension methods and modules do not work without unicode
2720 support.
2721
Georg Brandl26543b12008-01-21 18:36:51 +00002722- Issue #1882: when compiling code from a string, encoding cookies in the
2723 second line of code were not always recognized correctly.
2724
Georg Brandl14404b62008-01-19 19:27:05 +00002725- Issue #1679: "0x" was taken as a valid integer literal.
2726
Georg Brandl6caad7d2008-01-26 14:19:22 +00002727- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002728 added.
2729
Christian Heimesc94e2b52008-01-14 04:13:37 +00002730- sys.float_info / PyFloat_GetInfo: The floating point information
2731 object was converted from a dict to a specialized structseq object.
2732
Georg Brandl3ee81df2008-05-17 18:14:43 +00002733- Patch #1816: Added sys.flags structseq. It exposes the status of
2734 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002735
Georg Brandl3ee81df2008-05-17 18:14:43 +00002736- Objects/structseq.c: Implemented new structseq representation. The
2737 patch makes structseqs (e.g. the return value of os.stat) more
2738 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Patch #1700288: added a type attribute cache that caches method
2741 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002742
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002743- Bug #1776: __import__() no longer accepts filenames on any platform.
2744 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002745
Georg Brandlaed6c662008-01-07 17:25:53 +00002746- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2747
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2749 envvar and sys.dont_write_bytecode attribute. All these can be set
2750 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002751
Georg Brandl3ee81df2008-05-17 18:14:43 +00002752- Improve some exception messages when Windows fails to load an
2753 extension module. Now we get for example '%1 is not a valid Win32
2754 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002755
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002758- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2759 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002760
Christian Heimes0a8143f2007-12-18 23:22:54 +00002761- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002762 and INF. float("nan"), float("inf") and float("-inf") now work on
2763 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- Compiler now generates simpler and faster code for dictionary
2766 literals. The oparg for BUILD_MAP now indicates an estimated
2767 dictionary size. There is a new opcode, STORE_MAP, for adding
2768 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002769
Georg Brandl3ee81df2008-05-17 18:14:43 +00002770- Issue #1638: %zd configure test fails on Linux.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Patch #1739468: Directories and zipfiles containing a __main__.py
2798 file can now be directly executed by passing their name to the
2799 interpreter. The directory/zipfile is automatically inserted as the
2800 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Issue #1265: Fix a problem with sys.settrace, if the tracing
2803 function uses a generator expression when at the same time the
2804 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002805
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002806- sets and frozensets now have an isdisjoint() method.
2807
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002808- optimize the performance of builtin.sum().
2809
Neal Norwitz44f326e2007-10-05 05:29:17 +00002810- Fix warnings found by the new version of the Coverity checker.
2811
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- The enumerate() builtin function is no longer bounded to sequences
2813 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2814 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002815
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Issue #1686386: Tuple's tp_repr did not take into account the
2817 possibility of having a self-referential tuple, which is possible
2818 from C code. Nor did object's tp_str consider that a type's tp_str
2819 could do something that could lead to an inifinite recursion.
2820 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2821 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002822
Georg Brandl3ee81df2008-05-17 18:14:43 +00002823- Issue #1164: It was possible to trigger deadlock when using the
2824 'print' statement to write to a file since the GIL was not released
2825 as needed. Now PyObject_Print() does the right thing along with
2826 various tp_print implementations of the built-in types and those in
2827 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002828
Georg Brandl3ee81df2008-05-17 18:14:43 +00002829- Issue #1147: Exceptions were directly allowing string exceptions in
2830 their throw() method even though string exceptions no longer
2831 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002832
Georg Brandl3ee81df2008-05-17 18:14:43 +00002833- Issue #1096: Prevent a segfault from getting the repr of a very
2834 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002835
Brett Cannon1e534b52007-09-07 04:18:30 +00002836- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837 PyObject_Call() never calling back out to Python code to trigger
2838 recursion depth updates/checks. Required the creation of a static
2839 RuntimeError instance in case normalizing an exception put the
2840 recursion check value past its limit. Fixes crashers
2841 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002842
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00002856- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002857 __*__ attributes. (Some already existed, e.g., __doc__ and
2858 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002859
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002860- Add -3 option to the interpreter to warn about features that are
2861 deprecated and will be changed/removed in Python 3.0.
2862
Georg Brandl2134e752007-05-21 20:34:16 +00002863- Patch #1686487: you can now pass any mapping after '**' in function
2864 calls.
2865
Collin Winter62903052007-05-18 23:11:24 +00002866- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867 "except E as target:". This is to provide forwards compatibility
2868 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002869
Brett Cannon229cee22007-05-05 01:34:02 +00002870- Deprecate BaseException.message as per PEP 352.
2871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002873 inherited from a builtin base.
2874
Vinay Sajip8549ce32007-05-06 17:53:37 +00002875- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002876 setting a plain string, ie don't expand to single letter identifiers.
2877
Raymond Hettinger13936692007-04-11 18:40:58 +00002878- Request #1191699: Slices can now be pickled.
2879
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002880- Request #1193128: str.translate() now allows a None argument for
2881 translations that only remove characters without re-mapping the
2882 remaining characters.
2883
Georg Brandl5cb76c12007-03-21 09:00:39 +00002884- Patch #1682205: a TypeError while unpacking an iterable is no longer
2885 masked by a generic one with the message "unpack non-sequence".
2886
Neal Norwitzaa754b72007-03-21 06:39:48 +00002887- Remove unused file Python/fmod.c.
2888
Guido van Rossum143b5642007-03-23 04:58:42 +00002889- Bug #1683368: The object.__init__() and object.__new__() methods are
2890 now stricter in rejecting excess arguments. The only time when
2891 either allows excess arguments is when it is not overridden and the
2892 other one is. For backwards compatibility, when both are
2893 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002894 warning later). Also, type.__init__() insists on the same signature
2895 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002896
Georg Brandl3ee81df2008-05-17 18:14:43 +00002897- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2898 object to complex using its __complex__() method before falling back
2899 to the __float__() method. Therefore, the functions in the cmath
2900 module now can operate on objects that define a __complex__()
2901 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002902
Georg Brandl3ee81df2008-05-17 18:14:43 +00002903- Patch #1623563: allow __class__ assignment for classes with
2904 __slots__. The old and the new class are still required to have the
2905 same slot names.

2918
Georg Brandl7b9c5552007-03-12 14:30:05 +00002919- Bug #1678647: write a newline after printing an exception in any
2920 case, even when converting the value to a string failed.

Georg Brandl871f1bc2007-03-12 13:17:36 +00002922- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002923 its argument, if it exists. If not, it will work like before. This
2924 allows customizing the output of dir() in the presence of a
2925 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002937- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl3ee81df2008-05-17 18:14:43 +00003449 the client's request was successfully received, understood, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00003975 time so that opening a database previously created with the DB_DUP
3976 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3977 opens. Specifically: dictionary assignment to a DB object will
3978 replace all values for a given key when the database allows
3979 duplicate values. DB users should use DB.put(k, v) when they want
3980 to store duplicates; not DB[k] = v.

3987 characters with ASCII value less than 32. Also, it correctly quotes
3988 dots only if they occur on a single line, as opposed to the previous
3989 behavior of quoting dots if they are the second character of any
3990 line.
