199 reading from stdin so that existing input does not confuse it and

210 than the current precision) in shift and rotate.
211
R. David Murray7034db32009-10-27 23:39:06 +0000212- Issue #7082: When falling back to the MIME 'name' parameter, the

1149What's New in Python 2.6.1
1150==========================
1151
1152*Release date: 04-Dec-2008*
1153
1154Core and Builtins
1155-----------------
1156
1157- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1158 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1159 instead of throwing a MemoryError.
1160
1161- Issue #4367: Python would segfault during compiling when the unicodedata
1162 module couldn't be imported and \N escapes were present.
1163
1164- Issue #4348: Some bytearray methods returned that didn't cause any change to
1165 the bytearray, returned the same bytearray instead of a copy.
1166
1167- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1168
1169- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1170
1171- Issue #4048: The parser module now correctly validates relative imports.
1172
1173- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1174 exec statement.
1175
1176- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1177 method does not return iterators for the 4th and 5th items.
1178
1179- Issue #4209: Enabling unicode_literals and the print_function in the same
1180 __future__ import didn't work.
1181
1182- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1183 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1184 really executed because I cannot move to such directory on win2k)
1185
1186- Issue #4069: When set.remove(element) is used with a set element, the element
1187 is temporarily replaced with an equivalent frozenset. But the eventual
1188 KeyError would always report the empty frozenset([]) as the missing key. Now
1189 it correctly refers to the initial element.
1190
1191- Fixed C99 style comments in several files. Python is now C89 compatible
1192 again.

1319- Issue #3850: recursion tests in Misc/find_recursion_limit.py can raise
1320 AttributeError instead of RuntimeError, depending in which C API call
1321 exactly the recursion limit is exceeded. Consequently, both exception types
1322 are caught and silenced.

1338
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001339- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1340
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001341- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1342 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1343 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1344 ``printf`` function, whereas PyString_FromFormat has an independent
1345 implementation and uses "%zd" on all platforms for size_t values.
1346 This makes a difference on win64, where ``printf`` needs "%Id" to display
1347 64bit values.
1348
Benjamin Peterson97179b02008-09-09 20:55:01 +00001349- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1350 error.
1351
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001352- Issue #3777: long() applied to a float object now always return a long
1353 object; previously an int would be returned for small values. the __long__
1354 method is allowed to return either an int or a long, but the behaviour of
1355 float objects should not change to respect backward compatibility.
1356
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001357- Issue #3751: str.rpartition would perform a left-partition when called with
1358 a unicode argument.
1359
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001360- Issue #3683: Fix compilation when --without-threads is given.
1361
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001362- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001363 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001364 was correctly parsed but parsing of subsequent arguments failed.
1365
Vinay Sajip35e3b032008-09-01 14:33:59 +00001366- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001367 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1368 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1369 when given a tuple of classes as second argument, were looking up
1370 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1371 type object.
1372
Neal Norwitz18aa3882008-08-24 05:04:52 +00001373- Fix crashes on memory allocation failure found with failmalloc.
1374
1375- Fix memory leaks found with valgrind and update suppressions file.
1376
1377- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1378
1379- Fix problem using wrong name in decimal module reported by pychecker.
1380
Christian Heimes7d4c3172008-08-22 19:47:25 +00001381- Silenced another compiler warning about a used but not defined
1382 function 'stringlib_contains_obj'.

1385 ``__delslice__``.
1386
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001387- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1388 library targets in the Makefile.
1389
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001390- Issue #1204: The configure script now tests for additional libraries
1391 that may be required when linking against readline. This fixes issues
1392 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Nick Coghland2e09382008-09-11 12:11:06 +00001409- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1410 silent misbehaviour when a single instance is nested in multiple
1411 with statements, or when the methods are invoked in the wrong order.
1412
Vinay Sajip844f7412008-09-09 13:42:08 +00001413- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1414
Nick Coghland2e09382008-09-11 12:11:06 +00001415- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001416 return a list or None rather than a custom object.
1417
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001418- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1442 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1443 for catch_warnings() also led to an improvement in the raising of a
1444 DeprecationWarning related to warnings.warn_explicit().
1445
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001446- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001507What's New in Python 2.6 beta 3?
1508================================

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001511
1512Core and Builtins
1513-----------------
1514
Guido van Rossumf8402962008-08-20 15:01:50 +00001515- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1516 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1517 extensions do not automatically benefit from the class attribute
1518 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1519 to their tp_flags field if they care. This is a backwards
1520 compatibility feature; in 3.0, all types will use the cache by
1521 default.
1522
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001523- Keyword arguments can now follow starred arguments. (``f(a, *args,
1524 keyword=23)`` is now valid syntax.)
1525
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001526- ctypes function pointers that are COM methods have a boolean True
1527 value again.
1528
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001529- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1530 by denying s# to parse objects that have a releasebuffer procedure,
1531 and introducing s*.
1532
Georg Brandl1e13ea92008-08-11 09:07:59 +00001533- Issue #3537: Fix an assertion failure when an empty but presized dict
1534 object was stored in the freelist.
1535
Mark Dickinsonb6467572008-08-04 21:30:09 +00001536- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1537 ValueError consistently across platforms.
1538
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001539- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1540 (64bit Unix, for example), unichr() would truncate its argument and return
1541 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1542
Neal Norwitze7d8be82008-07-31 17:17:14 +00001543- Apply security patches from Apple.
1544
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001545- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1546 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1547
Antoine Pitrou92f82162008-07-25 22:22:08 +00001548- Issue #1819: function calls with several named parameters are now on
1549 average 35% faster (as measured by pybench).
1550
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001551- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1552 the python debugger steps into a class statement: the free variables (local
1553 variables defined in an outer scope) would be deleted from the outer scope.
1554
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001555- Issue #2620: Overflow checking when allocating or reallocating memory
1556 was not always being done properly in some python types and extension
1557 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1558 all been updated to perform better checks and places in the code that
1559 would previously leak memory on the error path when such an allocation
1560 failed have been fixed.

1566
Benjamin Petersone977ad42008-08-20 01:42:01 +00001567- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1568 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1569
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001570- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1571 version reported by these tools does not necessarily follow the python
1572 version numbering scheme, so the module is less strict when parsing it.
1573
Nick Coghlanf70385a2008-08-18 12:42:46 +00001574- Issue #2235: Added Py3k warnings for types which will become unhashable
1575 under the stricter __hash__ inheritance rules in 3.0. Several types
1576 which did not meet the rules for hash invariants and were already
1577 unhashable in 3.0 have now been explicitly flagged as unhashable in
1578 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1579 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1580
Brett Cannon88f801d2008-08-18 00:46:22 +00001581- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1582 imported into the module but exposed as part of the module's API.
1583
Brett Cannon7b96f072008-08-18 00:41:11 +00001584- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1585
Brett Cannon46225e72008-08-18 00:36:52 +00001586- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1587
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001588- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1589
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001590- Issue #3575: Incremental decoder's decode function now takes bytearray

1694
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001695- Issue #643841: The language reference now provides more detailed

1707-----------------
1708
Georg Brandl3e483f62008-07-16 22:57:41 +00001709- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1710 its methods now allow for items objects that can be converted to
1711 an integer using operator.index().
1712
Mark Dickinson64b7e502008-07-16 09:40:03 +00001713- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1714 produced a ValueError instead of giving the correct float.
1715
Eric Smitha5fa5a22008-07-16 00:11:49 +00001716- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1717 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1718
Mark Dickinson7103aa42008-07-15 19:08:33 +00001719- Issue #3008: the float type has a new instance method 'float.hex'
1720 and a new class method 'float.fromhex' to convert floating-point
1721 numbers to and from hexadecimal strings, respectively.
1722
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001723- Issue #2235: __hash__ is once again inherited by default. To allow
1724 collections.Hashable to remain meaningful in the presence of the
1725 default hash implementation (object.__hash__), it is now possible
1726 to explicit block inheritance of hash by setting __hash__=None at
1727 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1728 level.
1729
Nick Coghlanb028f502008-07-13 14:52:36 +00001730- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1731 the parent module cannot be found while performing an absolute import.
1732 This means that an incorrectly defined __package__ attribute will
1733 now only prevent relative imports in that module rather than causing
1734 all imports from that module to fail.
1735
Nick Coghlan14ff9942008-07-08 14:21:42 +00001736- Issue #2517: Allow unicode messages in Exceptions again by correctly
1737 bypassing the instance dictionary when looking up __unicode__ on
1738 new-style classes.

1746 another thread's dictionary.
1747
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001748- Issue #3004: Minor change to slice.indices(): the start and stop
1749 arguments are now treated identically, making the behaviour easier
1750 to describe and understand. For example, slice(None, -10,
1751 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1752 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1753 10, -1).
1754
Georg Brandl278fc502008-07-19 12:46:12 +00001755- Issue #3219: Calling a function with repeated keyword arguments,
1756 f(a=2, a=23), would not cause a syntax error. This was a regression
1757 from 2.4 caused by the switch to the new compiler.

Georg Brandl278fc502008-07-19 12:46:12 +00001759- Issue #2862: Make int and float freelist management consistent with
1760 other freelists. Changes their CompactFreeList apis into

1767 api functions without holding the GIL, which could lead to a fatal
1768 error when they failed.
1769
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001770- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001795- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1796 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001797 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001798 content-length. The problem had been corrected in the 2.4 branch, but never

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001814- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Ronald Oussoren5640ce22008-06-05 12:58:24 +00002208
2209 This is controlled by the configure argument ``--with-universal-archs``:
2210
2211 - ``--with-universal-archs=all``: install 4-way universal
2212
2213 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2214
2215 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2216
2217 This option should be used in combination with ``--enable-universalsdk=``.

2270 original Python code has been kept as backup). This will allow for
2271 using the 'warning's machinery in such places as the parser where
2272 use of pure Python code is not possible. Both the ``showarning()``
2273 and ``formatwarning()`` gain an optional 'line' argument which is
2274 not called by default for backwards-compatibility reasons. Setting
2275 ``warnings.showwarning()`` to an implementation that lacks support
2276 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002339- Issue #2550: The approach used by client/server code for obtaining
2340 ports to listen on in network-oriented tests has been refined in an
2341 effort to facilitate running multiple instances of the entire
2342 regression test suite in parallel without issue.
2343 test_support.bind_port() has been fixed such that it will always
2344 return a unique port -- which wasn't always the case with the
2345 previous implementation, especially if socket options had been set
2346 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2347 new implementation of bind_port() will actually raise an exception
2348 if it is passed an AF_INET/SOCK_STREAM socket with either the
2349 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2350 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2351 the socket it's been passed. This currently only applies to
2352 Windows. This option prevents any other sockets from binding to the
2353 host/port we've bound to, thus removing the possibility of the
2354 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2355 when a second SOCK_STREAM socket binds and accepts to a host/port
2356 that's already been bound by another socket. The optional preferred
2357 port parameter to bind_port() has been removed. Under no
2358 circumstances should tests be hard coding ports!
2359
2360 test_support.find_unused_port() has also been introduced, which will
2361 pass a temporary socket object to bind_port() in order to obtain an
2362 unused port. The temporary socket object is then closed and
2363 deleted, and the port is returned. This method should only be used
2364 for obtaining an unused port in order to pass to an external program
2365 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2366 a parameter to a server-oriented class that doesn't give you direct
2367 access to the underlying socket used.
2368
2369 Finally, test_support.HOST has been introduced, which should be used
2370 for the host argument of any relevant socket calls (i.e. bind and
2371 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002372
2373 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002374 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002375 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2376 test_asynchat and test_socket_ssl.
2377
Georg Brandl3ee81df2008-05-17 18:14:43 +00002378 It is now possible for multiple instances of the regression test
2379 suite to run in parallel without issue.

2436 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
2437 this case, like normal unicode literals and the 'unicode-escape'
2438 codec.

2646-----------------
2647
Fred Drakea8ee94b2008-03-01 02:45:07 +00002648- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002649 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002654
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002655- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002656 issue 215555 for a discussion.
2657
Eric Smitha73fbe72008-02-23 03:09:44 +00002658- Added the future_builtins module, which contains hex() and oct().
2659 These are the PEP 3127 version of these functions, designed to be
2660 compatible with the hex() and oct() builtins from Python 3.0. They
2661 differ slightly in their output formats from the existing, unchanged
2662 Python 2.6 builtins. The expected usage of the future_builtins
2663 module is:
2664 from future_builtins import hex, oct
2665
Eric Smith7ef40bf2008-02-20 23:34:22 +00002666- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2667 exponents for exponents with absolute value < 100. Follows C99
2668 standard. This is a change on Windows, which would use 3 digits.
2669 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2670 so that any alterations it does to the resulting string will be
2671 available in stringlib/formatter.h (for float.__format__).
2672
Eric Smith5a3c1352008-02-19 13:21:56 +00002673- Implemented PEP 3101, Advanced String Formatting. This adds a new
2674 builtin format(); a format() method for str and unicode; a
2675 __format__() method to object, str, unicode, int, long, float, and
2676 datetime; the class string.Formatter; and the C API
2677 PyObject_Format().
2678
Georg Brandl3ee81df2008-05-17 18:14:43 +00002679- Fixed several potential crashes, all caused by specially crafted
2680 __del__ methods exploiting objects in temporarily inconsistent
2681 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002682
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002683- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684 prevent a possible crash: an Abstract Base Class would try to access
2685 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Fixed repr() and str() of complex numbers with infinity or nan as
2688 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Clear all free lists during a gc.collect() of the highest generation
2691 in order to allow pymalloc to free more arenas. Python may give back
2692 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Issue #2045: Fix an infinite recursion triggered when printing a
2695 subclass of collections.defaultdict, if its default_factory is set
2696 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002697
Christian Heimesf75dbef2008-02-08 00:11:31 +00002698- Fixed a minor memory leak in dictobject.c. The content of the free
2699 list was not freed on interpreter shutdown.
2700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Limit free list of method and builtin function objects to 256
2702 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002704- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2705 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002706 to compact the internal free lists of pre-allocted ints and floats.
2707
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2709 calls. Python expected the return type int but the fork familie
2710 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002711
Georg Brandl3ee81df2008-05-17 18:14:43 +00002712- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2713 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002724- Patch #1473257: generator objects gain a gi_code attribute. This is
2725 the same object as the func_code attribute of the function that
2726 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002727
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Issue #1920: "while 0" statements were completely removed by the
2729 compiler, even in the presence of an "else" clause, which is
2730 supposed to be run when the condition is false. Now the compiler
2731 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002732
Guido van Rossumeead05f2008-01-24 18:21:02 +00002733- A few crashers fixed: weakref_in_del.py (issue #1377858);
2734 loosing_dict_ref.py (issue #1303614, test67.py);
2735 borrowed_ref_[34].py (not in tracker).
2736
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002737- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002738 suppressed while an extension is loaded by calling SetErrorMode in
2739 dynload_win.c. The error is still reported properly.
2740
Georg Brandl3ee81df2008-05-17 18:14:43 +00002741- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002742 several extension methods and modules do not work without unicode
2743 support.
2744
Georg Brandl26543b12008-01-21 18:36:51 +00002745- Issue #1882: when compiling code from a string, encoding cookies in the
2746 second line of code were not always recognized correctly.
2747
Georg Brandl14404b62008-01-19 19:27:05 +00002748- Issue #1679: "0x" was taken as a valid integer literal.
2749
Georg Brandl6caad7d2008-01-26 14:19:22 +00002750- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002751 added.
2752
Christian Heimesc94e2b52008-01-14 04:13:37 +00002753- sys.float_info / PyFloat_GetInfo: The floating point information
2754 object was converted from a dict to a specialized structseq object.
2755
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756- Patch #1816: Added sys.flags structseq. It exposes the status of
2757 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002758
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759- Objects/structseq.c: Implemented new structseq representation. The
2760 patch makes structseqs (e.g. the return value of os.stat) more
2761 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002762
Georg Brandl3ee81df2008-05-17 18:14:43 +00002763- Patch #1700288: added a type attribute cache that caches method
2764 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002765
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002766- Bug #1776: __import__() no longer accepts filenames on any platform.
2767 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002768
Georg Brandlaed6c662008-01-07 17:25:53 +00002769- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2770

2772 envvar and sys.dont_write_bytecode attribute. All these can be set
2773 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002774
Georg Brandl3ee81df2008-05-17 18:14:43 +00002775- Improve some exception messages when Windows fails to load an
2776 extension module. Now we get for example '%1 is not a valid Win32
2777 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002778

Christian Heimes0a8143f2007-12-18 23:22:54 +00002784- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002785 and INF. float("nan"), float("inf") and float("-inf") now work on
2786 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002787
Georg Brandl3ee81df2008-05-17 18:14:43 +00002788- Compiler now generates simpler and faster code for dictionary
2789 literals. The oparg for BUILD_MAP now indicates an estimated
2790 dictionary size. There is a new opcode, STORE_MAP, for adding
2791 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002792

Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- Patch #1739468: Directories and zipfiles containing a __main__.py
2821 file can now be directly executed by passing their name to the
2822 interpreter. The directory/zipfile is automatically inserted as the
2823 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002824
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825- Issue #1265: Fix a problem with sys.settrace, if the tracing
2826 function uses a generator expression when at the same time the
2827 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002828
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002829- sets and frozensets now have an isdisjoint() method.
2830

2832
Neal Norwitz44f326e2007-10-05 05:29:17 +00002833- Fix warnings found by the new version of the Coverity checker.
2834
Georg Brandl3ee81df2008-05-17 18:14:43 +00002835- The enumerate() builtin function is no longer bounded to sequences
2836 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2837 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002838
Georg Brandl3ee81df2008-05-17 18:14:43 +00002839- Issue #1686386: Tuple's tp_repr did not take into account the
2840 possibility of having a self-referential tuple, which is possible
2841 from C code. Nor did object's tp_str consider that a type's tp_str
2842 could do something that could lead to an inifinite recursion.
2843 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2844 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002845
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846- Issue #1164: It was possible to trigger deadlock when using the
2847 'print' statement to write to a file since the GIL was not released
2848 as needed. Now PyObject_Print() does the right thing along with
2849 various tp_print implementations of the built-in types and those in
2850 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002851
Georg Brandl3ee81df2008-05-17 18:14:43 +00002852- Issue #1147: Exceptions were directly allowing string exceptions in
2853 their throw() method even though string exceptions no longer
2854 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Issue #1096: Prevent a segfault from getting the repr of a very
2857 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002858
Brett Cannon1e534b52007-09-07 04:18:30 +00002859- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002860 PyObject_Call() never calling back out to Python code to trigger
2861 recursion depth updates/checks. Required the creation of a static
2862 RuntimeError instance in case normalizing an exception put the
2863 recursion check value past its limit. Fixes crashers
2864 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002865

Neal Norwitz0ac60192007-05-27 04:08:54 +00002879- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002880 __*__ attributes. (Some already existed, e.g., __doc__ and
2881 __name__.)

2885
Georg Brandl2134e752007-05-21 20:34:16 +00002886- Patch #1686487: you can now pass any mapping after '**' in function
2887 calls.
2888
Collin Winter62903052007-05-18 23:11:24 +00002889- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002890 "except E as target:". This is to provide forwards compatibility
2891 with Python 3.0.

2897
Vinay Sajip8549ce32007-05-06 17:53:37 +00002898- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002899 setting a plain string, ie don't expand to single letter identifiers.
2900
Raymond Hettinger13936692007-04-11 18:40:58 +00002901- Request #1191699: Slices can now be pickled.
2902
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002903- Request #1193128: str.translate() now allows a None argument for

2905 remaining characters.
2906
Georg Brandl5cb76c12007-03-21 09:00:39 +00002907- Patch #1682205: a TypeError while unpacking an iterable is no longer
2908 masked by a generic one with the message "unpack non-sequence".
2909
Neal Norwitzaa754b72007-03-21 06:39:48 +00002910- Remove unused file Python/fmod.c.
2911
Guido van Rossum143b5642007-03-23 04:58:42 +00002912- Bug #1683368: The object.__init__() and object.__new__() methods are
2913 now stricter in rejecting excess arguments. The only time when
2914 either allows excess arguments is when it is not overridden and the
2915 other one is. For backwards compatibility, when both are
2916 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002917 warning later). Also, type.__init__() insists on the same signature
2918 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00002920- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2921 object to complex using its __complex__() method before falling back
2922 to the __float__() method. Therefore, the functions in the cmath
2923 module now can operate on objects that define a __complex__()
2924 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002946 its argument, if it exists. If not, it will work like before. This
2947 allows customizing the output of dir() in the presence of a
2948 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00002960- Patch #703779: unset __file__ in __main__ after running a file. This

Georg Brandl2c1375c2006-10-12 11:27:59 +00003030- Bug #1545497: when given an explicit base, int() did ignore NULs
3031 embedded in the string to convert.
3032
Georg Brandl846f73a2006-10-08 07:11:54 +00003033- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl4e933132006-09-06 20:05:58 +00003063- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003081 generator expressions (x for x, in ... ) works again. Fixing this
3082 problem required changing the .pyc magic number. This means that

Georg Brandl3ee81df2008-05-17 18:14:43 +00003998 time so that opening a database previously created with the DB_DUP
3999 or DB_DUPSORT flag set will keep the proper behavior on subsequent
4000 opens. Specifically: dictionary assignment to a DB object will
4001 replace all values for a given key when the database allows
4002 duplicate values. DB users should use DB.put(k, v) when they want
4003 to store duplicates; not DB[k] = v.

4010 characters with ASCII value less than 32. Also, it correctly quotes
4011 dots only if they occur on a single line, as opposed to the previous
4012 behavior of quoting dots if they are the second character of any
4013 line.
