Georg Brandld2094602008-12-05 08:51:30 +0000708 method on file objects with closefd=False. The file descriptor is still
709 kept open but the file object behaves like a closed file. The ``FileIO``
710 object also got a new readonly attribute ``closefd``.

918 302 conformant loader) will now work correctly in most cases (they
919 are still subject to the constraints that exist for all code running

1079What's New in Python 2.6.1
1080==========================
1081
1082*Release date: 04-Dec-2008*
1083
1084Core and Builtins
1085-----------------
1086
1087- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1088 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1089 instead of throwing a MemoryError.
1090
1091- Issue #4367: Python would segfault during compiling when the unicodedata
1092 module couldn't be imported and \N escapes were present.
1093
1094- Issue #4348: Some bytearray methods returned that didn't cause any change to
1095 the bytearray, returned the same bytearray instead of a copy.
1096
1097- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1098
1099- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1100
1101- Issue #4048: The parser module now correctly validates relative imports.
1102
1103- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1109- Issue #4209: Enabling unicode_literals and the print_function in the same
1110 __future__ import didn't work.
1111
1112- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1113 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1114 really executed because I cannot move to such directory on win2k)
1115
1116- Issue #4069: When set.remove(element) is used with a set element, the element
1117 is temporarily replaced with an equivalent frozenset. But the eventual
1118 KeyError would always report the empty frozenset([]) as the missing key. Now
1119 it correctly refers to the initial element.
1120
1121- Fixed C99 style comments in several files. Python is now C89 compatible
1122 again.

1270
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001271- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1272 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1273 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1274 ``printf`` function, whereas PyString_FromFormat has an independent
1275 implementation and uses "%zd" on all platforms for size_t values.
1276 This makes a difference on win64, where ``printf`` needs "%Id" to display

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001437What's New in Python 2.6 beta 3?
1438================================
1439
Barry Warsaw07a4a382008-08-21 01:15:08 +00001440*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001441
1442Core and Builtins
1443-----------------
1444
Guido van Rossumf8402962008-08-20 15:01:50 +00001445- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1446 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1447 extensions do not automatically benefit from the class attribute
1448 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1449 to their tp_flags field if they care. This is a backwards
1450 compatibility feature; in 3.0, all types will use the cache by
1451 default.
1452
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001453- Keyword arguments can now follow starred arguments. (``f(a, *args,
1454 keyword=23)`` is now valid syntax.)
1455
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001456- ctypes function pointers that are COM methods have a boolean True
1457 value again.
1458
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001459- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1460 by denying s# to parse objects that have a releasebuffer procedure,
1461 and introducing s*.
1462
Georg Brandl1e13ea92008-08-11 09:07:59 +00001463- Issue #3537: Fix an assertion failure when an empty but presized dict
1464 object was stored in the freelist.
1465
Mark Dickinsonb6467572008-08-04 21:30:09 +00001466- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1467 ValueError consistently across platforms.
1468
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001469- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1470 (64bit Unix, for example), unichr() would truncate its argument and return
1471 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1472
Neal Norwitze7d8be82008-07-31 17:17:14 +00001473- Apply security patches from Apple.
1474
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001475- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1476 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1477
Antoine Pitrou92f82162008-07-25 22:22:08 +00001478- Issue #1819: function calls with several named parameters are now on
1479 average 35% faster (as measured by pybench).
1480
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001481- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1482 the python debugger steps into a class statement: the free variables (local
1483 variables defined in an outer scope) would be deleted from the outer scope.
1484
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001485- Issue #2620: Overflow checking when allocating or reallocating memory
1486 was not always being done properly in some python types and extension
1487 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1488 all been updated to perform better checks and places in the code that
1489 would previously leak memory on the error path when such an allocation
1490 failed have been fixed.

1494
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001495- Issue #3612: Added some missing basic types in ctypes.wintypes.
1496
Benjamin Petersone977ad42008-08-20 01:42:01 +00001497- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1498 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1499
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001500- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1501 version reported by these tools does not necessarily follow the python
1502 version numbering scheme, so the module is less strict when parsing it.
1503
Nick Coghlanf70385a2008-08-18 12:42:46 +00001504- Issue #2235: Added Py3k warnings for types which will become unhashable
1505 under the stricter __hash__ inheritance rules in 3.0. Several types
1506 which did not meet the rules for hash invariants and were already
1507 unhashable in 3.0 have now been explicitly flagged as unhashable in
1508 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1509 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1510
Brett Cannon88f801d2008-08-18 00:46:22 +00001511- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1512 imported into the module but exposed as part of the module's API.
1513
Brett Cannon7b96f072008-08-18 00:41:11 +00001514- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1515
Brett Cannon46225e72008-08-18 00:36:52 +00001516- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001518- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1519
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001520- Issue #3575: Incremental decoder's decode function now takes bytearray
1521 by using 's*' instead of 't#'.
1522
Jesus Cea585ad8a2009-07-02 15:37:21 +00001523- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001524 fails unicode conversion on 2nd parameter. (windows only)
1525
Facundo Batista94f243a2008-08-17 03:38:39 +00001526- Issue 2464. urllib2 now supports a malformation in the URL received
1527 in a redirect.
1528
Brett Cannonabe423e2008-08-16 21:47:07 +00001529- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001530 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001531
Facundo Batistaeb90b782008-08-16 14:44:07 +00001532- Issue #2776: fixed small issue when handling an URL with double slash
1533 after a 302 response in the case of not going through a proxy.
1534
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001535- Issue #2676: in the email package, content-type parsing was hanging on
1536 pathological input because of quadratic or exponential behaviour of a
1537 regular expression.
1538
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001539- Issue #3476: binary buffered reading through the new "io" library is now
1540 thread-safe.
1541
Brett Cannonbf3157b2008-08-14 05:00:03 +00001542- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1543 since mimetools itself is deprecated. Because modules are cached, all
1544 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1545
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001546- Issue #3134: shutil referenced undefined WindowsError symbol.
1547
Robert Schuppenies14646332008-08-10 11:01:53 +00001548- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1549 menu entries were not deleted.
1550
Brett Cannon83e81842008-08-09 23:30:55 +00001551- Copied the implementation of reduce() to _functools.reduce() to have a
1552 version that did not raise a DeprecationWarning under -3.
1553
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001554- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1555 a MemoryError rather than silently stop the iteration.
1556
Guido van Rossum59ce9012008-08-09 14:55:34 +00001557- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1558 to _sre.compile() will now be rejected. This should not affect anybody
1559 since the re.compile() function never generates invalid re-bytecode.
1560
Skip Montanaroa032bf42008-08-08 22:52:51 +00001561- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1562 upon first access it can be automatically initialized from the csv file if
1563 it wasn't initialized during instantiation.
1564
Brett Cannon3aa2a492008-08-06 22:28:09 +00001565- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1566 the reload() built-in has been removed.
1567
Brett Cannon7e30b672008-08-04 21:52:25 +00001568- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001569 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001580 asking for a specific length. This problem only affected files opened
1581 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001582
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001583- Issue #3449: Update decimal module to use most recent specification
1584 (v. 1.68) and tests (v. 2.58) from IBM.
1585

1624
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001625- Issue #643841: The language reference now provides more detailed

1632================================
1633
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001634*Release date: 17-Jul-2008*

1637-----------------
1638
Georg Brandl3e483f62008-07-16 22:57:41 +00001639- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1640 its methods now allow for items objects that can be converted to
1641 an integer using operator.index().
1642
Mark Dickinson64b7e502008-07-16 09:40:03 +00001643- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1644 produced a ValueError instead of giving the correct float.
1645
Eric Smitha5fa5a22008-07-16 00:11:49 +00001646- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1647 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1648
Mark Dickinson7103aa42008-07-15 19:08:33 +00001649- Issue #3008: the float type has a new instance method 'float.hex'
1650 and a new class method 'float.fromhex' to convert floating-point
1651 numbers to and from hexadecimal strings, respectively.
1652
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001653- Issue #2235: __hash__ is once again inherited by default. To allow
1654 collections.Hashable to remain meaningful in the presence of the
1655 default hash implementation (object.__hash__), it is now possible
1656 to explicit block inheritance of hash by setting __hash__=None at
1657 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1658 level.
1659
Nick Coghlanb028f502008-07-13 14:52:36 +00001660- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1661 the parent module cannot be found while performing an absolute import.
1662 This means that an incorrectly defined __package__ attribute will
1663 now only prevent relative imports in that module rather than causing
1664 all imports from that module to fail.
1665
Nick Coghlan14ff9942008-07-08 14:21:42 +00001666- Issue #2517: Allow unicode messages in Exceptions again by correctly

1671 set to a custom object whose write() method happens to install
1672 another file in sys.stdout.
1673
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001674- Issue #3088: Corrected a race condition in classes derived from
1675 threading.local: the first member set by a thread could be saved in
1676 another thread's dictionary.
1677
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001678- Issue #3004: Minor change to slice.indices(): the start and stop
1679 arguments are now treated identically, making the behaviour easier
1680 to describe and understand. For example, slice(None, -10,
1681 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1682 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1683 10, -1).
1684
Georg Brandl278fc502008-07-19 12:46:12 +00001685- Issue #3219: Calling a function with repeated keyword arguments,
1686 f(a=2, a=23), would not cause a syntax error. This was a regression
1687 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001688
Georg Brandl278fc502008-07-19 12:46:12 +00001689- Issue #2862: Make int and float freelist management consistent with
1690 other freelists. Changes their CompactFreeList apis into
1691 ClearFreeList apis and calls them via gc.collect().

1697 api functions without holding the GIL, which could lead to a fatal
1698 error when they failed.
1699
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001700- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001725- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1726 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001727 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001728 content-length. The problem had been corrected in the 2.4 branch, but never
1729 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001744- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1745 handling is now the same as that of other special attributes like __name__).
1746
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001747- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002199- Issue #1631171: Re-implement the 'warnings' module in C (the
2200 original Python code has been kept as backup). This will allow for
2201 using the 'warning's machinery in such places as the parser where
2202 use of pure Python code is not possible. Both the ``showarning()``
2203 and ``formatwarning()`` gain an optional 'line' argument which is
2204 not called by default for backwards-compatibility reasons. Setting
2205 ``warnings.showwarning()`` to an implementation that lacks support
2206 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002269- Issue #2550: The approach used by client/server code for obtaining
2270 ports to listen on in network-oriented tests has been refined in an
2271 effort to facilitate running multiple instances of the entire
2272 regression test suite in parallel without issue.
2273 test_support.bind_port() has been fixed such that it will always
2274 return a unique port -- which wasn't always the case with the
2275 previous implementation, especially if socket options had been set
2276 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2277 new implementation of bind_port() will actually raise an exception
2278 if it is passed an AF_INET/SOCK_STREAM socket with either the
2279 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2280 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2281 the socket it's been passed. This currently only applies to
2282 Windows. This option prevents any other sockets from binding to the
2283 host/port we've bound to, thus removing the possibility of the
2284 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2285 when a second SOCK_STREAM socket binds and accepts to a host/port
2286 that's already been bound by another socket. The optional preferred
2287 port parameter to bind_port() has been removed. Under no
2288 circumstances should tests be hard coding ports!
2289
2290 test_support.find_unused_port() has also been introduced, which will
2291 pass a temporary socket object to bind_port() in order to obtain an
2292 unused port. The temporary socket object is then closed and
2293 deleted, and the port is returned. This method should only be used
2294 for obtaining an unused port in order to pass to an external program
2295 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2296 a parameter to a server-oriented class that doesn't give you direct
2297 access to the underlying socket used.
2298
2299 Finally, test_support.HOST has been introduced, which should be used
2300 for the host argument of any relevant socket calls (i.e. bind and
2301 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002302
2303 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002304 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002305 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2306 test_asynchat and test_socket_ssl.
2307
Georg Brandl3ee81df2008-05-17 18:14:43 +00002308 It is now possible for multiple instances of the regression test
2309 suite to run in parallel without issue.

2577
Fred Drakea8ee94b2008-03-01 02:45:07 +00002578- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002579 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002584
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002585- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002586 issue 215555 for a discussion.
2587
Eric Smitha73fbe72008-02-23 03:09:44 +00002588- Added the future_builtins module, which contains hex() and oct().
2589 These are the PEP 3127 version of these functions, designed to be
2590 compatible with the hex() and oct() builtins from Python 3.0. They
2591 differ slightly in their output formats from the existing, unchanged
2592 Python 2.6 builtins. The expected usage of the future_builtins
2593 module is:
2594 from future_builtins import hex, oct
2595
Eric Smith7ef40bf2008-02-20 23:34:22 +00002596- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2597 exponents for exponents with absolute value < 100. Follows C99
2598 standard. This is a change on Windows, which would use 3 digits.
2599 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2600 so that any alterations it does to the resulting string will be
2601 available in stringlib/formatter.h (for float.__format__).
2602
Eric Smith5a3c1352008-02-19 13:21:56 +00002603- Implemented PEP 3101, Advanced String Formatting. This adds a new
2604 builtin format(); a format() method for str and unicode; a
2605 __format__() method to object, str, unicode, int, long, float, and
2606 datetime; the class string.Formatter; and the C API
2607 PyObject_Format().
2608
Georg Brandl3ee81df2008-05-17 18:14:43 +00002609- Fixed several potential crashes, all caused by specially crafted
2610 __del__ methods exploiting objects in temporarily inconsistent
2611 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002612
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002613- Issue #2115: Important speedup in setting __slot__ attributes. Also

2622 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002623
Georg Brandl3ee81df2008-05-17 18:14:43 +00002624- Issue #2045: Fix an infinite recursion triggered when printing a

2635 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002636 to compact the internal free lists of pre-allocted ints and floats.
2637
Georg Brandl3ee81df2008-05-17 18:14:43 +00002638- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2639 calls. Python expected the return type int but the fork familie
2640 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002654- Patch #1473257: generator objects gain a gi_code attribute. This is
2655 the same object as the func_code attribute of the function that
2656 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002657
Georg Brandl3ee81df2008-05-17 18:14:43 +00002658- Issue #1920: "while 0" statements were completely removed by the
2659 compiler, even in the presence of an "else" clause, which is
2660 supposed to be run when the condition is false. Now the compiler
2661 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002662

Georg Brandl6caad7d2008-01-26 14:19:22 +00002680- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002681 added.
2682
Christian Heimesc94e2b52008-01-14 04:13:37 +00002683- sys.float_info / PyFloat_GetInfo: The floating point information
2684 object was converted from a dict to a specialized structseq object.
2685
Georg Brandl3ee81df2008-05-17 18:14:43 +00002686- Patch #1816: Added sys.flags structseq. It exposes the status of
2687 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Objects/structseq.c: Implemented new structseq representation. The
2690 patch makes structseqs (e.g. the return value of os.stat) more
2691 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002692
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693- Patch #1700288: added a type attribute cache that caches method
2694 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002695
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002696- Bug #1776: __import__() no longer accepts filenames on any platform.
2697 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002698
Georg Brandlaed6c662008-01-07 17:25:53 +00002699- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2702 envvar and sys.dont_write_bytecode attribute. All these can be set
2703 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002704
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705- Improve some exception messages when Windows fails to load an
2706 extension module. Now we get for example '%1 is not a valid Win32
2707 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002708
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002711- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2712 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002713
Christian Heimes0a8143f2007-12-18 23:22:54 +00002714- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002715 and INF. float("nan"), float("inf") and float("-inf") now work on
2716 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002717
Georg Brandl3ee81df2008-05-17 18:14:43 +00002718- Compiler now generates simpler and faster code for dictionary
2719 literals. The oparg for BUILD_MAP now indicates an estimated
2720 dictionary size. There is a new opcode, STORE_MAP, for adding
2721 entries to the dictionary.

2739 running, and if the deallocation of its frames somehow calls the
2740 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002741

Georg Brandl3ee81df2008-05-17 18:14:43 +00002750- Patch #1739468: Directories and zipfiles containing a __main__.py
2751 file can now be directly executed by passing their name to the
2752 interpreter. The directory/zipfile is automatically inserted as the
2753 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002754
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755- Issue #1265: Fix a problem with sys.settrace, if the tracing
2756 function uses a generator expression when at the same time the
2757 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002758
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002759- sets and frozensets now have an isdisjoint() method.
2760

2762
Neal Norwitz44f326e2007-10-05 05:29:17 +00002763- Fix warnings found by the new version of the Coverity checker.
2764
Georg Brandl3ee81df2008-05-17 18:14:43 +00002765- The enumerate() builtin function is no longer bounded to sequences
2766 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2767 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002768
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769- Issue #1686386: Tuple's tp_repr did not take into account the
2770 possibility of having a self-referential tuple, which is possible
2771 from C code. Nor did object's tp_str consider that a type's tp_str
2772 could do something that could lead to an inifinite recursion.
2773 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2774 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002775
Georg Brandl3ee81df2008-05-17 18:14:43 +00002776- Issue #1164: It was possible to trigger deadlock when using the
2777 'print' statement to write to a file since the GIL was not released
2778 as needed. Now PyObject_Print() does the right thing along with
2779 various tp_print implementations of the built-in types and those in
2780 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- Issue #1147: Exceptions were directly allowing string exceptions in
2783 their throw() method even though string exceptions no longer
2784 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002785
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786- Issue #1096: Prevent a segfault from getting the repr of a very
2787 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002788
Brett Cannon1e534b52007-09-07 04:18:30 +00002789- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002790 PyObject_Call() never calling back out to Python code to trigger
2791 recursion depth updates/checks. Required the creation of a static
2792 RuntimeError instance in case normalizing an exception put the
2793 recursion check value past its limit. Fixes crashers
2794 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- Patch #1031213: Decode source line in SyntaxErrors back to its

2800 with %G.
2801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Prevent expandtabs() on string and unicode objects from causing a
2803 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002809- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810 __*__ attributes. (Some already existed, e.g., __doc__ and
2811 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002812
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002813- Add -3 option to the interpreter to warn about features that are
2814 deprecated and will be changed/removed in Python 3.0.
2815
Georg Brandl2134e752007-05-21 20:34:16 +00002816- Patch #1686487: you can now pass any mapping after '**' in function
2817 calls.
2818
Collin Winter62903052007-05-18 23:11:24 +00002819- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820 "except E as target:". This is to provide forwards compatibility
2821 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002822
Brett Cannon229cee22007-05-05 01:34:02 +00002823- Deprecate BaseException.message as per PEP 352.
2824
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002826 inherited from a builtin base.
2827
Vinay Sajip8549ce32007-05-06 17:53:37 +00002828- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002829 setting a plain string, ie don't expand to single letter identifiers.
2830
Raymond Hettinger13936692007-04-11 18:40:58 +00002831- Request #1191699: Slices can now be pickled.
2832
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002833- Request #1193128: str.translate() now allows a None argument for
2834 translations that only remove characters without re-mapping the
2835 remaining characters.
2836
Georg Brandl5cb76c12007-03-21 09:00:39 +00002837- Patch #1682205: a TypeError while unpacking an iterable is no longer
2838 masked by a generic one with the message "unpack non-sequence".
2839
Neal Norwitzaa754b72007-03-21 06:39:48 +00002840- Remove unused file Python/fmod.c.
2841
Guido van Rossum143b5642007-03-23 04:58:42 +00002842- Bug #1683368: The object.__init__() and object.__new__() methods are
2843 now stricter in rejecting excess arguments. The only time when
2844 either allows excess arguments is when it is not overridden and the
2845 other one is. For backwards compatibility, when both are
2846 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002847 warning later). Also, type.__init__() insists on the same signature
2848 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002849
Georg Brandl3ee81df2008-05-17 18:14:43 +00002850- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2851 object to complex using its __complex__() method before falling back
2852 to the __float__() method. Therefore, the functions in the cmath
2853 module now can operate on objects that define a __complex__()
2854 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Patch #1623563: allow __class__ assignment for classes with
2857 __slots__. The old and the new class are still required to have the
2858 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002859

Georg Brandl3ee81df2008-05-17 18:14:43 +00002863- Patch #1462488: Python no longer segfaults when
2864 ``object.__reduce_ex__()`` is called with an object that is faking
2865 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002866
Georg Brandl3ee81df2008-05-17 18:14:43 +00002867- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002870- Patch #1444529: the builtin compile() now accepts keyword arguments.
2871
Georg Brandl7b9c5552007-03-12 14:30:05 +00002872- Bug #1678647: write a newline after printing an exception in any
2873 case, even when converting the value to a string failed.
2874
Georg Brandl871f1bc2007-03-12 13:17:36 +00002875- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002876 its argument, if it exists. If not, it will work like before. This
2877 allows customizing the output of dir() in the presence of a
2878 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002879
Collin Winter276887b2007-03-12 16:11:39 +00002880- Patch #922167: Python no longer segfaults when faced with infinitely
2881 self-recursive reload() calls (as reported by bug #742342).
2882
Georg Brandl3ee81df2008-05-17 18:14:43 +00002883- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002886- Patch #1491866: change the complex() constructor to allow
2887 parthensized forms. This means complex(repr(x)) now works instead of
2888 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002889
Georg Brandlaa2321b2007-03-07 00:40:28 +00002890- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002891 makes the filenames the warning module prints much more sensible
2892 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002893
Georg Brandl49aafc92007-03-07 00:34:46 +00002894- Variant of patch #697613: don't exit the interpreter on a SystemExit
2895 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002896 variable is given, but break into the interactive interpreter just
2897 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002905- Patch #1674228: when assigning a slice (old-style), check for the
2906 sq_ass_slice instead of the sq_slice slot.
2907
Georg Brandl3ee81df2008-05-17 18:14:43 +00002908- When printing an unraisable error, don't print exceptions. before
2909 the name. This duplicates the behavior whening normally printing
2910 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002911
Georg Brandl3ee81df2008-05-17 18:14:43 +00002912- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003412- Added a timeout parameter to the constructor of other protocols
3413 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3414 work started with create_connection() and timeout in httplib, and
3415 closes patch #723312.
3416
Vinay Sajip8549ce32007-05-06 17:53:37 +00003417- Patch #1676823: Added create_connection() to socket.py, which may be
3418 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003419 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003420

3441
Georg Brandlf66b6032007-03-14 08:27:52 +00003442- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003443 AttributeError instead of an IOError when the server's response
3444 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003445
Georg Brandl3ee81df2008-05-17 18:14:43 +00003446- Patch #957650: "%var%" environment variable references are now
3447 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00003450- Patch #1429539: pdb now correctly initializes the __main__ module
3451 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003452 correctly now.
3453
Georg Brandlbad6f192007-03-13 21:32:56 +00003454- The nonobvious commands.getstatus() function is now deprecated.

3460
Georg Brandl3ee81df2008-05-17 18:14:43 +00003461- Patch #1530482: add pydoc.render_doc() which returns the
3462 documentation for a thing instead of paging it to stdout, which

3471 parameter which can be set to False to prevent the default
3472 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003473
Georg Brandl9e6b4702007-03-13 18:15:41 +00003474- Patch #1581073: add a flag to textwrap that prevents the dropping of
3475 whitespace while wrapping.
3476
Georg Brandl92a6bae2007-03-13 17:43:32 +00003477- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003478 are set for invalid interpolation sequences that would lead to
3479 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003480

3519 Python would crash instead of raising an error.
3520

3522 returned string up to the first NUL character.
3523

3533
Georg Brandl3ee81df2008-05-17 18:14:43 +00003534- unittest now verifies more of its assumptions. In particular,
3535 TestCase and TestSuite subclasses (not instances) are no longer
3536 accepted in TestSuite.addTest(). This should cause no
3537 incompatibility since it never made sense with ordinary subclasses
3538 -- the failure just occurred later, with a more cumbersome
3539 exception.

3549
Georg Brandl3ee81df2008-05-17 18:14:43 +00003550- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003928 time so that opening a database previously created with the DB_DUP
3929 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3930 opens. Specifically: dictionary assignment to a DB object will
3931 replace all values for a given key when the database allows
3932 duplicate values. DB users should use DB.put(k, v) when they want
3933 to store duplicates; not DB[k] = v.

3940 characters with ASCII value less than 32. Also, it correctly quotes
3941 dots only if they occur on a single line, as opposed to the previous
3942 behavior of quoting dots if they are the second character of any
3943 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003944

Georg Brandl3ee81df2008-05-17 18:14:43 +00004321- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4322 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
