201 than the current precision) in shift and rotate.
202
R. David Murray7034db32009-10-27 23:39:06 +0000203- Issue #7082: When falling back to the MIME 'name' parameter, the

942 do an explicit seek to the end of file (so that e.g. tell() returns the
943 file size rather than 0). This is consistent with the behaviour of the
944 traditional 2.x file object.

1140What's New in Python 2.6.1
1141==========================
1142
1143*Release date: 04-Dec-2008*
1144
1145Core and Builtins
1146-----------------
1147
1148- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1149 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1150 instead of throwing a MemoryError.
1151
1152- Issue #4367: Python would segfault during compiling when the unicodedata
1153 module couldn't be imported and \N escapes were present.
1154
1155- Issue #4348: Some bytearray methods returned that didn't cause any change to
1156 the bytearray, returned the same bytearray instead of a copy.
1157
1158- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1159
1160- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1161
1162- Issue #4048: The parser module now correctly validates relative imports.
1163
1164- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1165 exec statement.
1166
1167- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1168 method does not return iterators for the 4th and 5th items.
1169
1170- Issue #4209: Enabling unicode_literals and the print_function in the same
1171 __future__ import didn't work.
1172
1173- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1174 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1175 really executed because I cannot move to such directory on win2k)
1176
1177- Issue #4069: When set.remove(element) is used with a set element, the element
1178 is temporarily replaced with an equivalent frozenset. But the eventual
1179 KeyError would always report the empty frozenset([]) as the missing key. Now
1180 it correctly refers to the initial element.
1181
1182- Fixed C99 style comments in several files. Python is now C89 compatible
1183 again.

1310- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1311 AttributeError instead of RuntimeError, depending in which C API call
1312 exactly the recursion limit is exceeded. Consequently, both exception types
1313 are caught and silenced.

1329
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001330- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1331
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001332- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1333 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1334 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1335 ``printf`` function, whereas PyString_FromFormat has an independent
1336 implementation and uses "%zd" on all platforms for size_t values.
1337 This makes a difference on win64, where ``printf`` needs "%Id" to display
1338 64bit values.
1339
Benjamin Peterson97179b02008-09-09 20:55:01 +00001340- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1341 error.
1342
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001343- Issue #3777: long() applied to a float object now always return a long
1344 object; previously an int would be returned for small values. the __long__
1345 method is allowed to return either an int or a long, but the behaviour of
1346 float objects should not change to respect backward compatibility.
1347
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001348- Issue #3751: str.rpartition would perform a left-partition when called with
1349 a unicode argument.
1350
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001351- Issue #3683: Fix compilation when --without-threads is given.
1352
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001353- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001354 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001355 was correctly parsed but parsing of subsequent arguments failed.
1356
Vinay Sajip35e3b032008-09-01 14:33:59 +00001357- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001358 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1359 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1360 when given a tuple of classes as second argument, were looking up
1361 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1362 type object.
1363
Neal Norwitz18aa3882008-08-24 05:04:52 +00001364- Fix crashes on memory allocation failure found with failmalloc.
1365
1366- Fix memory leaks found with valgrind and update suppressions file.
1367
1368- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1369
1370- Fix problem using wrong name in decimal module reported by pychecker.
1371
Christian Heimes7d4c3172008-08-22 19:47:25 +00001372- Silenced another compiler warning about a used but not defined
1373 function 'stringlib_contains_obj'.

1376 ``__delslice__``.
1377
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001378- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1379 library targets in the Makefile.
1380
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001381- Issue #1204: The configure script now tests for additional libraries
1382 that may be required when linking against readline. This fixes issues
1383 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001400- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1401 silent misbehaviour when a single instance is nested in multiple
1402 with statements, or when the methods are invoked in the wrong order.
1403
Vinay Sajip844f7412008-09-09 13:42:08 +00001404- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1405
Nick Coghland2e09382008-09-11 12:11:06 +00001406- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001407 return a list or None rather than a custom object.
1408
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001409- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1433 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1434 for catch_warnings() also led to an improvement in the raising of a
1435 DeprecationWarning related to warnings.warn_explicit().
1436
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001437- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001498What's New in Python 2.6 beta 3?
1499================================

Barry Warsaw07a4a382008-08-21 01:15:08 +00001501*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001502
1503Core and Builtins
1504-----------------
1505
Guido van Rossumf8402962008-08-20 15:01:50 +00001506- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1507 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1508 extensions do not automatically benefit from the class attribute
1509 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1510 to their tp_flags field if they care. This is a backwards
1511 compatibility feature; in 3.0, all types will use the cache by
1512 default.
1513
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001514- Keyword arguments can now follow starred arguments. (``f(a, *args,
1515 keyword=23)`` is now valid syntax.)
1516
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001517- ctypes function pointers that are COM methods have a boolean True
1518 value again.
1519
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001520- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1521 by denying s# to parse objects that have a releasebuffer procedure,
1522 and introducing s*.
1523
Georg Brandl1e13ea92008-08-11 09:07:59 +00001524- Issue #3537: Fix an assertion failure when an empty but presized dict
1525 object was stored in the freelist.
1526
Mark Dickinsonb6467572008-08-04 21:30:09 +00001527- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1528 ValueError consistently across platforms.
1529
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001530- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1531 (64bit Unix, for example), unichr() would truncate its argument and return
1532 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1533
Neal Norwitze7d8be82008-07-31 17:17:14 +00001534- Apply security patches from Apple.
1535
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001536- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1537 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1538
Antoine Pitrou92f82162008-07-25 22:22:08 +00001539- Issue #1819: function calls with several named parameters are now on
1540 average 35% faster (as measured by pybench).
1541
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001542- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1543 the python debugger steps into a class statement: the free variables (local
1544 variables defined in an outer scope) would be deleted from the outer scope.
1545
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001546- Issue #2620: Overflow checking when allocating or reallocating memory
1547 was not always being done properly in some python types and extension
1548 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1549 all been updated to perform better checks and places in the code that
1550 would previously leak memory on the error path when such an allocation
1551 failed have been fixed.

1559 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1560
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001561- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1562 version reported by these tools does not necessarily follow the python
1563 version numbering scheme, so the module is less strict when parsing it.
1564
Nick Coghlanf70385a2008-08-18 12:42:46 +00001565- Issue #2235: Added Py3k warnings for types which will become unhashable
1566 under the stricter __hash__ inheritance rules in 3.0. Several types
1567 which did not meet the rules for hash invariants and were already
1568 unhashable in 3.0 have now been explicitly flagged as unhashable in
1569 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1570 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1571
Brett Cannon88f801d2008-08-18 00:46:22 +00001572- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1573 imported into the module but exposed as part of the module's API.
1574

1580
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001581- Issue #3575: Incremental decoder's decode function now takes bytearray
1582 by using 's*' instead of 't#'.
1583
Jesus Cea585ad8a2009-07-02 15:37:21 +00001584- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001585 fails unicode conversion on 2nd parameter. (windows only)
1586
Facundo Batista94f243a2008-08-17 03:38:39 +00001587- Issue 2464. urllib2 now supports a malformation in the URL received
1588 in a redirect.

1619 to _sre.compile() will now be rejected. This should not affect anybody
1620 since the re.compile() function never generates invalid re-bytecode.

Antoine Pitroude781a42008-08-09 12:43:23 +00001641 asking for a specific length. This problem only affected files opened

1685
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001686- Issue #643841: The language reference now provides more detailed

1698-----------------
1699
Georg Brandl3e483f62008-07-16 22:57:41 +00001700- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1701 its methods now allow for items objects that can be converted to
1702 an integer using operator.index().
1703
Mark Dickinson64b7e502008-07-16 09:40:03 +00001704- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1705 produced a ValueError instead of giving the correct float.
1706
Eric Smitha5fa5a22008-07-16 00:11:49 +00001707- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1708 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1709
Mark Dickinson7103aa42008-07-15 19:08:33 +00001710- Issue #3008: the float type has a new instance method 'float.hex'
1711 and a new class method 'float.fromhex' to convert floating-point
1712 numbers to and from hexadecimal strings, respectively.
1713
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001714- Issue #2235: __hash__ is once again inherited by default. To allow
1715 collections.Hashable to remain meaningful in the presence of the
1716 default hash implementation (object.__hash__), it is now possible
1717 to explicit block inheritance of hash by setting __hash__=None at
1718 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1719 level.
1720
Nick Coghlanb028f502008-07-13 14:52:36 +00001721- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1722 the parent module cannot be found while performing an absolute import.
1723 This means that an incorrectly defined __package__ attribute will
1724 now only prevent relative imports in that module rather than causing
1725 all imports from that module to fail.
1726
Nick Coghlan14ff9942008-07-08 14:21:42 +00001727- Issue #2517: Allow unicode messages in Exceptions again by correctly
1728 bypassing the instance dictionary when looking up __unicode__ on
1729 new-style classes.

1737 another thread's dictionary.
1738
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001739- Issue #3004: Minor change to slice.indices(): the start and stop
1740 arguments are now treated identically, making the behaviour easier
1741 to describe and understand. For example, slice(None, -10,
1742 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1743 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1744 10, -1).
1745
Georg Brandl278fc502008-07-19 12:46:12 +00001746- Issue #3219: Calling a function with repeated keyword arguments,
1747 f(a=2, a=23), would not cause a syntax error. This was a regression
1748 from 2.4 caused by the switch to the new compiler.

1758 api functions without holding the GIL, which could lead to a fatal
1759 error when they failed.
1760
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001761- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001786- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1787 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001788 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001789 content-length. The problem had been corrected in the 2.4 branch, but never
1790 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001805- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1807
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001808- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Brett Cannonb61d8012008-05-11 23:39:04 +00002194- ``Lib/lib-old`` is now added to sys.path.
2195
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002196- On MacOS X it is now possible to install the framework in 64-bit
2197 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002198 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002199
2200 This is controlled by the configure argument ``--with-universal-archs``:
2201
2202 - ``--with-universal-archs=all``: install 4-way universal
2203
2204 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2205
2206 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2207
2208 This option should be used in combination with ``--enable-universalsdk=``.
2209
2210 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00002260- Issue #1631171: Re-implement the 'warnings' module in C (the
2261 original Python code has been kept as backup). This will allow for
2262 using the 'warning's machinery in such places as the parser where
2263 use of pure Python code is not possible. Both the ``showarning()``
2264 and ``formatwarning()`` gain an optional 'line' argument which is
2265 not called by default for backwards-compatibility reasons. Setting
2266 ``warnings.showwarning()`` to an implementation that lacks support
2267 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002309- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002310 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002330- Issue #2550: The approach used by client/server code for obtaining
2331 ports to listen on in network-oriented tests has been refined in an
2332 effort to facilitate running multiple instances of the entire
2333 regression test suite in parallel without issue.
2334 test_support.bind_port() has been fixed such that it will always
2335 return a unique port -- which wasn't always the case with the
2336 previous implementation, especially if socket options had been set
2337 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2338 new implementation of bind_port() will actually raise an exception
2339 if it is passed an AF_INET/SOCK_STREAM socket with either the
2340 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2341 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2342 the socket it's been passed. This currently only applies to
2343 Windows. This option prevents any other sockets from binding to the
2344 host/port we've bound to, thus removing the possibility of the
2345 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2346 when a second SOCK_STREAM socket binds and accepts to a host/port
2347 that's already been bound by another socket. The optional preferred
2348 port parameter to bind_port() has been removed. Under no
2349 circumstances should tests be hard coding ports!
2350
2351 test_support.find_unused_port() has also been introduced, which will
2352 pass a temporary socket object to bind_port() in order to obtain an
2353 unused port. The temporary socket object is then closed and
2354 deleted, and the port is returned. This method should only be used
2355 for obtaining an unused port in order to pass to an external program
2356 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2357 a parameter to a server-oriented class that doesn't give you direct
2358 access to the underlying socket used.
2359
2360 Finally, test_support.HOST has been introduced, which should be used
2361 for the host argument of any relevant socket calls (i.e. bind and
2362 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002363
2364 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002365 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002366 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2367 test_asynchat and test_socket_ssl.
2368
Georg Brandl3ee81df2008-05-17 18:14:43 +00002369 It is now possible for multiple instances of the regression test
2370 suite to run in parallel without issue.

2637-----------------
2638
Fred Drakea8ee94b2008-03-01 02:45:07 +00002639- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002640 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002645
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002646- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002647 issue 215555 for a discussion.
2648
Eric Smitha73fbe72008-02-23 03:09:44 +00002649- Added the future_builtins module, which contains hex() and oct().
2650 These are the PEP 3127 version of these functions, designed to be
2651 compatible with the hex() and oct() builtins from Python 3.0. They
2652 differ slightly in their output formats from the existing, unchanged
2653 Python 2.6 builtins. The expected usage of the future_builtins
2654 module is:
2655 from future_builtins import hex, oct
2656
Eric Smith7ef40bf2008-02-20 23:34:22 +00002657- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2658 exponents for exponents with absolute value < 100. Follows C99
2659 standard. This is a change on Windows, which would use 3 digits.
2660 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2661 so that any alterations it does to the resulting string will be
2662 available in stringlib/formatter.h (for float.__format__).
2663
Eric Smith5a3c1352008-02-19 13:21:56 +00002664- Implemented PEP 3101, Advanced String Formatting. This adds a new
2665 builtin format(); a format() method for str and unicode; a
2666 __format__() method to object, str, unicode, int, long, float, and
2667 datetime; the class string.Formatter; and the C API
2668 PyObject_Format().
2669
Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Fixed several potential crashes, all caused by specially crafted
2671 __del__ methods exploiting objects in temporarily inconsistent
2672 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002673
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002674- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002675 prevent a possible crash: an Abstract Base Class would try to access
2676 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002677

Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Clear all free lists during a gc.collect() of the highest generation
2682 in order to allow pymalloc to free more arenas. Python may give back
2683 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002684
Georg Brandl3ee81df2008-05-17 18:14:43 +00002685- Issue #2045: Fix an infinite recursion triggered when printing a
2686 subclass of collections.defaultdict, if its default_factory is set
2687 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002688
Christian Heimesf75dbef2008-02-08 00:11:31 +00002689- Fixed a minor memory leak in dictobject.c. The content of the free
2690 list was not freed on interpreter shutdown.
2691
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692- Limit free list of method and builtin function objects to 256
2693 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2696 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002697 to compact the internal free lists of pre-allocted ints and floats.
2698
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2700 calls. Python expected the return type int but the fork familie
2701 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2704 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2707 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and

Georg Brandl3ee81df2008-05-17 18:14:43 +00002712- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2713 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002714
Georg Brandl3ee81df2008-05-17 18:14:43 +00002715- Patch #1473257: generator objects gain a gi_code attribute. This is
2716 the same object as the func_code attribute of the function that
2717 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002718
Georg Brandl3ee81df2008-05-17 18:14:43 +00002719- Issue #1920: "while 0" statements were completely removed by the
2720 compiler, even in the presence of an "else" clause, which is
2721 supposed to be run when the condition is false. Now the compiler
2722 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002723
Guido van Rossumeead05f2008-01-24 18:21:02 +00002724- A few crashers fixed: weakref_in_del.py (issue #1377858);
2725 loosing_dict_ref.py (issue #1303614, test67.py);
2726 borrowed_ref_[34].py (not in tracker).
2727
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002728- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002729 suppressed while an extension is loaded by calling SetErrorMode in
2730 dynload_win.c. The error is still reported properly.
2731
Georg Brandl3ee81df2008-05-17 18:14:43 +00002732- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002733 several extension methods and modules do not work without unicode
2734 support.
2735
Georg Brandl26543b12008-01-21 18:36:51 +00002736- Issue #1882: when compiling code from a string, encoding cookies in the
2737 second line of code were not always recognized correctly.
2738
Georg Brandl14404b62008-01-19 19:27:05 +00002739- Issue #1679: "0x" was taken as a valid integer literal.
2740
Georg Brandl6caad7d2008-01-26 14:19:22 +00002741- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002742 added.
2743
Christian Heimesc94e2b52008-01-14 04:13:37 +00002744- sys.float_info / PyFloat_GetInfo: The floating point information
2745 object was converted from a dict to a specialized structseq object.
2746
Georg Brandl3ee81df2008-05-17 18:14:43 +00002747- Patch #1816: Added sys.flags structseq. It exposes the status of
2748 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002749
Georg Brandl3ee81df2008-05-17 18:14:43 +00002750- Objects/structseq.c: Implemented new structseq representation. The
2751 patch makes structseqs (e.g. the return value of os.stat) more
2752 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Patch #1700288: added a type attribute cache that caches method
2755 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002756
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002757- Bug #1776: __import__() no longer accepts filenames on any platform.
2758 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002759

2763 envvar and sys.dont_write_bytecode attribute. All these can be set
2764 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002765
Georg Brandl3ee81df2008-05-17 18:14:43 +00002766- Improve some exception messages when Windows fails to load an
2767 extension module. Now we get for example '%1 is not a valid Win32
2768 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002769

Christian Heimes0a8143f2007-12-18 23:22:54 +00002775- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002776 and INF. float("nan"), float("inf") and float("-inf") now work on
2777 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002778
Georg Brandl3ee81df2008-05-17 18:14:43 +00002779- Compiler now generates simpler and faster code for dictionary
2780 literals. The oparg for BUILD_MAP now indicates an estimated
2781 dictionary size. There is a new opcode, STORE_MAP, for adding
2782 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002811- Patch #1739468: Directories and zipfiles containing a __main__.py
2812 file can now be directly executed by passing their name to the
2813 interpreter. The directory/zipfile is automatically inserted as the
2814 first entry in sys.path.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002816- Issue #1265: Fix a problem with sys.settrace, if the tracing
2817 function uses a generator expression when at the same time the
2818 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002819
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002820- sets and frozensets now have an isdisjoint() method.
2821

2823
Neal Norwitz44f326e2007-10-05 05:29:17 +00002824- Fix warnings found by the new version of the Coverity checker.
2825
Georg Brandl3ee81df2008-05-17 18:14:43 +00002826- The enumerate() builtin function is no longer bounded to sequences
2827 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2828 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002829
Georg Brandl3ee81df2008-05-17 18:14:43 +00002830- Issue #1686386: Tuple's tp_repr did not take into account the
2831 possibility of having a self-referential tuple, which is possible
2832 from C code. Nor did object's tp_str consider that a type's tp_str
2833 could do something that could lead to an inifinite recursion.
2834 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2835 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002836
Georg Brandl3ee81df2008-05-17 18:14:43 +00002837- Issue #1164: It was possible to trigger deadlock when using the
2838 'print' statement to write to a file since the GIL was not released
2839 as needed. Now PyObject_Print() does the right thing along with
2840 various tp_print implementations of the built-in types and those in
2841 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002842
Georg Brandl3ee81df2008-05-17 18:14:43 +00002843- Issue #1147: Exceptions were directly allowing string exceptions in
2844 their throw() method even though string exceptions no longer
2845 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002846
Georg Brandl3ee81df2008-05-17 18:14:43 +00002847- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00002849
Brett Cannon1e534b52007-09-07 04:18:30 +00002850- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851 PyObject_Call() never calling back out to Python code to trigger
2852 recursion depth updates/checks. Required the creation of a static
2853 RuntimeError instance in case normalizing an exception put the
2854 recursion check value past its limit. Fixes crashers
2855 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002856

Neal Norwitz0ac60192007-05-27 04:08:54 +00002870- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871 __*__ attributes. (Some already existed, e.g., __doc__ and
2872 __name__.)

2876
Georg Brandl2134e752007-05-21 20:34:16 +00002877- Patch #1686487: you can now pass any mapping after '**' in function
2878 calls.
2879
Collin Winter62903052007-05-18 23:11:24 +00002880- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002881 "except E as target:". This is to provide forwards compatibility
2882 with Python 3.0.

2888
Vinay Sajip8549ce32007-05-06 17:53:37 +00002889- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002890 setting a plain string, ie don't expand to single letter identifiers.
2891
Raymond Hettinger13936692007-04-11 18:40:58 +00002892- Request #1191699: Slices can now be pickled.
2893
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002894- Request #1193128: str.translate() now allows a None argument for

2896 remaining characters.
2897
Georg Brandl5cb76c12007-03-21 09:00:39 +00002898- Patch #1682205: a TypeError while unpacking an iterable is no longer
2899 masked by a generic one with the message "unpack non-sequence".
2900
Neal Norwitzaa754b72007-03-21 06:39:48 +00002901- Remove unused file Python/fmod.c.
2902
Guido van Rossum143b5642007-03-23 04:58:42 +00002903- Bug #1683368: The object.__init__() and object.__new__() methods are
2904 now stricter in rejecting excess arguments. The only time when
2905 either allows excess arguments is when it is not overridden and the
2906 other one is. For backwards compatibility, when both are
2907 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002908 warning later). Also, type.__init__() insists on the same signature
2909 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002911- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2912 object to complex using its __complex__() method before falling back
2913 to the __float__() method. Therefore, the functions in the cmath
2914 module now can operate on objects that define a __complex__()
2915 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002937 its argument, if it exists. If not, it will work like before. This
2938 allows customizing the output of dir() in the presence of a

Georg Brandlaa2321b2007-03-07 00:40:28 +00002951- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003021- Bug #1545497: when given an explicit base, int() did ignore NULs
3022 embedded in the string to convert.
3023
Georg Brandl846f73a2006-10-08 07:11:54 +00003024- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00003054- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003072 generator expressions (x for x, in ... ) works again. Fixing this
3073 problem required changing the .pyc magic number. This means that

Georg Brandl3ee81df2008-05-17 18:14:43 +00003504 AttributeError instead of an IOError when the server's response
3505 didn't contain a valid HTTP status line.

3537
Georg Brandl92a6bae2007-03-13 17:43:32 +00003538- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539 are set for invalid interpolation sequences that would lead to
3540 errors on reading back those values.

3596 TestCase and TestSuite subclasses (not instances) are no longer

Georg Brandl3ee81df2008-05-17 18:14:43 +00003989 time so that opening a database previously created with the DB_DUP
3990 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3991 opens. Specifically: dictionary assignment to a DB object will
3992 replace all values for a given key when the database allows
3993 duplicate values. DB users should use DB.put(k, v) when they want
3994 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003995

4001 characters with ASCII value less than 32. Also, it correctly quotes
4002 dots only if they occur on a single line, as opposed to the previous
4003 behavior of quoting dots if they are the second character of any
4004 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00004005
