Georg Brandld2094602008-12-05 08:51:30 +0000703 method on file objects with closefd=False. The file descriptor is still

1074What's New in Python 2.6.1
1075==========================
1076
1077*Release date: 04-Dec-2008*
1078
1079Core and Builtins
1080-----------------
1081
1082- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1083 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1084 instead of throwing a MemoryError.
1085
1086- Issue #4367: Python would segfault during compiling when the unicodedata
1087 module couldn't be imported and \N escapes were present.
1088
1089- Issue #4348: Some bytearray methods returned that didn't cause any change to
1090 the bytearray, returned the same bytearray instead of a copy.
1091
1092- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1093
1094- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1095
1096- Issue #4048: The parser module now correctly validates relative imports.
1097
1098- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1105 __future__ import didn't work.
1106
1107- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1108 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1109 really executed because I cannot move to such directory on win2k)
1110
1111- Issue #4069: When set.remove(element) is used with a set element, the element
1112 is temporarily replaced with an equivalent frozenset. But the eventual
1113 KeyError would always report the empty frozenset([]) as the missing key. Now
1114 it correctly refers to the initial element.
1115

1117 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001266- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1267 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1268 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1269 ``printf`` function, whereas PyString_FromFormat has an independent
1270 implementation and uses "%zd" on all platforms for size_t values.
1271 This makes a difference on win64, where ``printf`` needs "%Id" to display

1367 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1368 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001391- Issue #2975: When compiling several extension modules with Visual Studio 2008
1392 from the same python interpreter, some environment variables would grow
1393 without limit.
1394
Benjamin Peterson37346b22008-08-23 20:27:43 +00001395- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001432What's New in Python 2.6 beta 3?
1433================================
1434
Barry Warsaw07a4a382008-08-21 01:15:08 +00001435*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001436
1437Core and Builtins
1438-----------------
1439
Guido van Rossumf8402962008-08-20 15:01:50 +00001440- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1441 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1442 extensions do not automatically benefit from the class attribute
1443 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1444 to their tp_flags field if they care. This is a backwards
1445 compatibility feature; in 3.0, all types will use the cache by
1446 default.
1447
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001448- Keyword arguments can now follow starred arguments. (``f(a, *args,
1449 keyword=23)`` is now valid syntax.)
1450
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001451- ctypes function pointers that are COM methods have a boolean True
1452 value again.
1453
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001454- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1455 by denying s# to parse objects that have a releasebuffer procedure,
1456 and introducing s*.
1457
Georg Brandl1e13ea92008-08-11 09:07:59 +00001458- Issue #3537: Fix an assertion failure when an empty but presized dict
1459 object was stored in the freelist.
1460
Mark Dickinsonb6467572008-08-04 21:30:09 +00001461- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1462 ValueError consistently across platforms.
1463
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001464- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1465 (64bit Unix, for example), unichr() would truncate its argument and return
1466 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1467
Neal Norwitze7d8be82008-07-31 17:17:14 +00001468- Apply security patches from Apple.
1469
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001470- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1471 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1472
Antoine Pitrou92f82162008-07-25 22:22:08 +00001473- Issue #1819: function calls with several named parameters are now on
1474 average 35% faster (as measured by pybench).
1475
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001476- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1477 the python debugger steps into a class statement: the free variables (local
1478 variables defined in an outer scope) would be deleted from the outer scope.
1479
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001480- Issue #2620: Overflow checking when allocating or reallocating memory
1481 was not always being done properly in some python types and extension
1482 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1483 all been updated to perform better checks and places in the code that
1484 would previously leak memory on the error path when such an allocation
1485 failed have been fixed.

1489
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001490- Issue #3612: Added some missing basic types in ctypes.wintypes.
1491
Benjamin Petersone977ad42008-08-20 01:42:01 +00001492- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1493 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1494
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001495- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1496 version reported by these tools does not necessarily follow the python
1497 version numbering scheme, so the module is less strict when parsing it.
1498
Nick Coghlanf70385a2008-08-18 12:42:46 +00001499- Issue #2235: Added Py3k warnings for types which will become unhashable
1500 under the stricter __hash__ inheritance rules in 3.0. Several types
1501 which did not meet the rules for hash invariants and were already
1502 unhashable in 3.0 have now been explicitly flagged as unhashable in
1503 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1504 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1505
Brett Cannon88f801d2008-08-18 00:46:22 +00001506- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1507 imported into the module but exposed as part of the module's API.
1508
Brett Cannon7b96f072008-08-18 00:41:11 +00001509- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1510
Brett Cannon46225e72008-08-18 00:36:52 +00001511- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001513- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1514
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001515- Issue #3575: Incremental decoder's decode function now takes bytearray
1516 by using 's*' instead of 't#'.
1517
Jesus Cea585ad8a2009-07-02 15:37:21 +00001518- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001519 fails unicode conversion on 2nd parameter. (windows only)
1520
Facundo Batista94f243a2008-08-17 03:38:39 +00001521- Issue 2464. urllib2 now supports a malformation in the URL received
1522 in a redirect.
1523
Brett Cannonabe423e2008-08-16 21:47:07 +00001524- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001525 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001526
Facundo Batistaeb90b782008-08-16 14:44:07 +00001527- Issue #2776: fixed small issue when handling an URL with double slash
1528 after a 302 response in the case of not going through a proxy.
1529
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001530- Issue #2676: in the email package, content-type parsing was hanging on
1531 pathological input because of quadratic or exponential behaviour of a
1532 regular expression.
1533
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001534- Issue #3476: binary buffered reading through the new "io" library is now
1535 thread-safe.
1536
Brett Cannonbf3157b2008-08-14 05:00:03 +00001537- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1538 since mimetools itself is deprecated. Because modules are cached, all
1539 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1540
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001541- Issue #3134: shutil referenced undefined WindowsError symbol.
1542
Robert Schuppenies14646332008-08-10 11:01:53 +00001543- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1544 menu entries were not deleted.
1545
Brett Cannon83e81842008-08-09 23:30:55 +00001546- Copied the implementation of reduce() to _functools.reduce() to have a
1547 version that did not raise a DeprecationWarning under -3.
1548
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001549- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1550 a MemoryError rather than silently stop the iteration.
1551
Guido van Rossum59ce9012008-08-09 14:55:34 +00001552- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1553 to _sre.compile() will now be rejected. This should not affect anybody
1554 since the re.compile() function never generates invalid re-bytecode.
1555
Skip Montanaroa032bf42008-08-08 22:52:51 +00001556- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1557 upon first access it can be automatically initialized from the csv file if
1558 it wasn't initialized during instantiation.
1559
Brett Cannon3aa2a492008-08-06 22:28:09 +00001560- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1561 the reload() built-in has been removed.
1562
Brett Cannon7e30b672008-08-04 21:52:25 +00001563- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001564 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001575 asking for a specific length. This problem only affected files opened
1576 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001577
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001578- Issue #3449: Update decimal module to use most recent specification
1579 (v. 1.68) and tests (v. 2.58) from IBM.
1580

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001626What's New in Python 2.6 beta 2?
1627================================
1628
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001629*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001631Core and Builtins
1632-----------------
1633
Georg Brandl3e483f62008-07-16 22:57:41 +00001634- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1635 its methods now allow for items objects that can be converted to
1636 an integer using operator.index().
1637
Mark Dickinson64b7e502008-07-16 09:40:03 +00001638- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1639 produced a ValueError instead of giving the correct float.
1640
Eric Smitha5fa5a22008-07-16 00:11:49 +00001641- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1642 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1643
Mark Dickinson7103aa42008-07-15 19:08:33 +00001644- Issue #3008: the float type has a new instance method 'float.hex'
1645 and a new class method 'float.fromhex' to convert floating-point
1646 numbers to and from hexadecimal strings, respectively.
1647
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001648- Issue #2235: __hash__ is once again inherited by default. To allow
1649 collections.Hashable to remain meaningful in the presence of the
1650 default hash implementation (object.__hash__), it is now possible
1651 to explicit block inheritance of hash by setting __hash__=None at
1652 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1653 level.
1654
Nick Coghlanb028f502008-07-13 14:52:36 +00001655- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1656 the parent module cannot be found while performing an absolute import.
1657 This means that an incorrectly defined __package__ attribute will
1658 now only prevent relative imports in that module rather than causing
1659 all imports from that module to fail.
1660
Nick Coghlan14ff9942008-07-08 14:21:42 +00001661- Issue #2517: Allow unicode messages in Exceptions again by correctly
1662 bypassing the instance dictionary when looking up __unicode__ on
1663 new-style classes.
1664
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001665- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1666 set to a custom object whose write() method happens to install
1667 another file in sys.stdout.
1668
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001669- Issue #3088: Corrected a race condition in classes derived from
1670 threading.local: the first member set by a thread could be saved in
1671 another thread's dictionary.
1672
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001673- Issue #3004: Minor change to slice.indices(): the start and stop
1674 arguments are now treated identically, making the behaviour easier
1675 to describe and understand. For example, slice(None, -10,
1676 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1677 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1678 10, -1).
1679
Georg Brandl278fc502008-07-19 12:46:12 +00001680- Issue #3219: Calling a function with repeated keyword arguments,
1681 f(a=2, a=23), would not cause a syntax error. This was a regression
1682 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001683
Georg Brandl278fc502008-07-19 12:46:12 +00001684- Issue #2862: Make int and float freelist management consistent with
1685 other freelists. Changes their CompactFreeList apis into
1686 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001691- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1692 api functions without holding the GIL, which could lead to a fatal
1693 error when they failed.
1694
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001695- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001719
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001720- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1721 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001722 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001723 content-length. The problem had been corrected in the 2.4 branch, but never
1724 merged into trunk.
1725
Georg Brandle78fbcc2008-07-05 10:13:36 +00001726- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001739- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1740 handling is now the same as that of other special attributes like __name__).
1741
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001742- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002194- Issue #1631171: Re-implement the 'warnings' module in C (the
2195 original Python code has been kept as backup). This will allow for
2196 using the 'warning's machinery in such places as the parser where
2197 use of pure Python code is not possible. Both the ``showarning()``
2198 and ``formatwarning()`` gain an optional 'line' argument which is
2199 not called by default for backwards-compatibility reasons. Setting
2200 ``warnings.showwarning()`` to an implementation that lacks support
2201 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002264- Issue #2550: The approach used by client/server code for obtaining
2265 ports to listen on in network-oriented tests has been refined in an
2266 effort to facilitate running multiple instances of the entire
2267 regression test suite in parallel without issue.
2268 test_support.bind_port() has been fixed such that it will always
2269 return a unique port -- which wasn't always the case with the
2270 previous implementation, especially if socket options had been set
2271 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2272 new implementation of bind_port() will actually raise an exception
2273 if it is passed an AF_INET/SOCK_STREAM socket with either the
2274 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2275 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2276 the socket it's been passed. This currently only applies to
2277 Windows. This option prevents any other sockets from binding to the
2278 host/port we've bound to, thus removing the possibility of the
2279 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2280 when a second SOCK_STREAM socket binds and accepts to a host/port
2281 that's already been bound by another socket. The optional preferred
2282 port parameter to bind_port() has been removed. Under no
2283 circumstances should tests be hard coding ports!
2284
2285 test_support.find_unused_port() has also been introduced, which will
2286 pass a temporary socket object to bind_port() in order to obtain an
2287 unused port. The temporary socket object is then closed and
2288 deleted, and the port is returned. This method should only be used
2289 for obtaining an unused port in order to pass to an external program
2290 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2291 a parameter to a server-oriented class that doesn't give you direct
2292 access to the underlying socket used.
2293
2294 Finally, test_support.HOST has been introduced, which should be used
2295 for the host argument of any relevant socket calls (i.e. bind and
2296 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002297
2298 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002299 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002300 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2301 test_asynchat and test_socket_ssl.
2302
Georg Brandl3ee81df2008-05-17 18:14:43 +00002303 It is now possible for multiple instances of the regression test
2304 suite to run in parallel without issue.

2572
Fred Drakea8ee94b2008-03-01 02:45:07 +00002573- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002574 644. The mode is now inherited from the py file.

Vinay Sajipb7edfc42008-04-02 21:10:23 +00002580- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002581 issue 215555 for a discussion.
2582
Eric Smitha73fbe72008-02-23 03:09:44 +00002583- Added the future_builtins module, which contains hex() and oct().
2584 These are the PEP 3127 version of these functions, designed to be
2585 compatible with the hex() and oct() builtins from Python 3.0. They
2586 differ slightly in their output formats from the existing, unchanged
2587 Python 2.6 builtins. The expected usage of the future_builtins
2588 module is:
2589 from future_builtins import hex, oct
2590
Eric Smith7ef40bf2008-02-20 23:34:22 +00002591- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2592 exponents for exponents with absolute value < 100. Follows C99
2593 standard. This is a change on Windows, which would use 3 digits.
2594 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2595 so that any alterations it does to the resulting string will be
2596 available in stringlib/formatter.h (for float.__format__).
2597
Eric Smith5a3c1352008-02-19 13:21:56 +00002598- Implemented PEP 3101, Advanced String Formatting. This adds a new
2599 builtin format(); a format() method for str and unicode; a
2600 __format__() method to object, str, unicode, int, long, float, and
2601 datetime; the class string.Formatter; and the C API
2602 PyObject_Format().
2603
Georg Brandl3ee81df2008-05-17 18:14:43 +00002604- Fixed several potential crashes, all caused by specially crafted
2605 __del__ methods exploiting objects in temporarily inconsistent
2606 state.

2630 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002631 to compact the internal free lists of pre-allocted ints and floats.
2632
Georg Brandl3ee81df2008-05-17 18:14:43 +00002633- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

2635 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002649- Patch #1473257: generator objects gain a gi_code attribute. This is
2650 the same object as the func_code attribute of the function that
2651 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002652
Georg Brandl3ee81df2008-05-17 18:14:43 +00002653- Issue #1920: "while 0" statements were completely removed by the
2654 compiler, even in the presence of an "else" clause, which is
2655 supposed to be run when the condition is false. Now the compiler
2656 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002657

Georg Brandl6caad7d2008-01-26 14:19:22 +00002675- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002676 added.
2677
Christian Heimesc94e2b52008-01-14 04:13:37 +00002678- sys.float_info / PyFloat_GetInfo: The floating point information
2679 object was converted from a dict to a specialized structseq object.
2680
Georg Brandl3ee81df2008-05-17 18:14:43 +00002681- Patch #1816: Added sys.flags structseq. It exposes the status of
2682 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002683
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- Objects/structseq.c: Implemented new structseq representation. The
2685 patch makes structseqs (e.g. the return value of os.stat) more
2686 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Patch #1700288: added a type attribute cache that caches method
2689 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002690
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002691- Bug #1776: __import__() no longer accepts filenames on any platform.
2692 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002693
Georg Brandlaed6c662008-01-07 17:25:53 +00002694- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2695
Georg Brandl3ee81df2008-05-17 18:14:43 +00002696- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2697 envvar and sys.dont_write_bytecode attribute. All these can be set
2698 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002699
Georg Brandl3ee81df2008-05-17 18:14:43 +00002700- Improve some exception messages when Windows fails to load an
2701 extension module. Now we get for example '%1 is not a valid Win32
2702 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002703
Georg Brandl3ee81df2008-05-17 18:14:43 +00002704- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2707 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002708
Christian Heimes0a8143f2007-12-18 23:22:54 +00002709- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710 and INF. float("nan"), float("inf") and float("-inf") now work on
2711 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002712
Georg Brandl3ee81df2008-05-17 18:14:43 +00002713- Compiler now generates simpler and faster code for dictionary
2714 literals. The oparg for BUILD_MAP now indicates an estimated
2715 dictionary size. There is a new opcode, STORE_MAP, for adding
2716 entries to the dictionary.

2734 running, and if the deallocation of its frames somehow calls the
2735 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002736

Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Patch #1739468: Directories and zipfiles containing a __main__.py
2746 file can now be directly executed by passing their name to the
2747 interpreter. The directory/zipfile is automatically inserted as the
2748 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002749
Georg Brandl3ee81df2008-05-17 18:14:43 +00002750- Issue #1265: Fix a problem with sys.settrace, if the tracing
2751 function uses a generator expression when at the same time the
2752 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002753
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002754- sets and frozensets now have an isdisjoint() method.
2755

2757
Neal Norwitz44f326e2007-10-05 05:29:17 +00002758- Fix warnings found by the new version of the Coverity checker.
2759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- The enumerate() builtin function is no longer bounded to sequences
2761 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2762 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002763
Georg Brandl3ee81df2008-05-17 18:14:43 +00002764- Issue #1686386: Tuple's tp_repr did not take into account the
2765 possibility of having a self-referential tuple, which is possible
2766 from C code. Nor did object's tp_str consider that a type's tp_str
2767 could do something that could lead to an inifinite recursion.
2768 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2769 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002770
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- Issue #1164: It was possible to trigger deadlock when using the
2772 'print' statement to write to a file since the GIL was not released
2773 as needed. Now PyObject_Print() does the right thing along with
2774 various tp_print implementations of the built-in types and those in
2775 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002776
Georg Brandl3ee81df2008-05-17 18:14:43 +00002777- Issue #1147: Exceptions were directly allowing string exceptions in
2778 their throw() method even though string exceptions no longer
2779 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002780
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781- Issue #1096: Prevent a segfault from getting the repr of a very
2782 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002783
Brett Cannon1e534b52007-09-07 04:18:30 +00002784- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002785 PyObject_Call() never calling back out to Python code to trigger
2786 recursion depth updates/checks. Required the creation of a static
2787 RuntimeError instance in case normalizing an exception put the
2788 recursion check value past its limit. Fixes crashers
2789 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Patch #1031213: Decode source line in SyntaxErrors back to its

2795 with %G.
2796
Georg Brandl3ee81df2008-05-17 18:14:43 +00002797- Prevent expandtabs() on string and unicode objects from causing a
2798 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002804- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805 __*__ attributes. (Some already existed, e.g., __doc__ and
2806 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002807
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002808- Add -3 option to the interpreter to warn about features that are
2809 deprecated and will be changed/removed in Python 3.0.
2810
Georg Brandl2134e752007-05-21 20:34:16 +00002811- Patch #1686487: you can now pass any mapping after '**' in function
2812 calls.
2813
Collin Winter62903052007-05-18 23:11:24 +00002814- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002815 "except E as target:". This is to provide forwards compatibility
2816 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002817
Brett Cannon229cee22007-05-05 01:34:02 +00002818- Deprecate BaseException.message as per PEP 352.
2819
Georg Brandl3ee81df2008-05-17 18:14:43 +00002820- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002821 inherited from a builtin base.
2822
Vinay Sajip8549ce32007-05-06 17:53:37 +00002823- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002824 setting a plain string, ie don't expand to single letter identifiers.
2825
Raymond Hettinger13936692007-04-11 18:40:58 +00002826- Request #1191699: Slices can now be pickled.
2827
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002828- Request #1193128: str.translate() now allows a None argument for
2829 translations that only remove characters without re-mapping the
2830 remaining characters.
2831
Georg Brandl5cb76c12007-03-21 09:00:39 +00002832- Patch #1682205: a TypeError while unpacking an iterable is no longer
2833 masked by a generic one with the message "unpack non-sequence".
2834
Neal Norwitzaa754b72007-03-21 06:39:48 +00002835- Remove unused file Python/fmod.c.
2836
Guido van Rossum143b5642007-03-23 04:58:42 +00002837- Bug #1683368: The object.__init__() and object.__new__() methods are
2838 now stricter in rejecting excess arguments. The only time when
2839 either allows excess arguments is when it is not overridden and the
2840 other one is. For backwards compatibility, when both are
2841 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002842 warning later). Also, type.__init__() insists on the same signature
2843 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002844
Georg Brandl3ee81df2008-05-17 18:14:43 +00002845- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2846 object to complex using its __complex__() method before falling back
2847 to the __float__() method. Therefore, the functions in the cmath
2848 module now can operate on objects that define a __complex__()
2849 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002850
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851- Patch #1623563: allow __class__ assignment for classes with
2852 __slots__. The old and the new class are still required to have the
2853 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Patch #1462488: Python no longer segfaults when
2859 ``object.__reduce_ex__()`` is called with an object that is faking
2860 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002861
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002865- Patch #1444529: the builtin compile() now accepts keyword arguments.
2866
Georg Brandl7b9c5552007-03-12 14:30:05 +00002867- Bug #1678647: write a newline after printing an exception in any
2868 case, even when converting the value to a string failed.
2869
Georg Brandl871f1bc2007-03-12 13:17:36 +00002870- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002871 its argument, if it exists. If not, it will work like before. This
2872 allows customizing the output of dir() in the presence of a
2873 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002874
Collin Winter276887b2007-03-12 16:11:39 +00002875- Patch #922167: Python no longer segfaults when faced with infinitely
2876 self-recursive reload() calls (as reported by bug #742342).
2877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Patch #1491866: change the complex() constructor to allow
2882 parthensized forms. This means complex(repr(x)) now works instead of
2883 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002884
Georg Brandlaa2321b2007-03-07 00:40:28 +00002885- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886 makes the filenames the warning module prints much more sensible
2887 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002888
Georg Brandl49aafc92007-03-07 00:34:46 +00002889- Variant of patch #697613: don't exit the interpreter on a SystemExit
2890 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002891 variable is given, but break into the interactive interpreter just
2892 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002900- Patch #1674228: when assigning a slice (old-style), check for the
2901 sq_ass_slice instead of the sq_slice slot.
2902
Georg Brandl3ee81df2008-05-17 18:14:43 +00002903- When printing an unraisable error, don't print exceptions. before
2904 the name. This duplicates the behavior whening normally printing
2905 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002906
Georg Brandl3ee81df2008-05-17 18:14:43 +00002907- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003407- Added a timeout parameter to the constructor of other protocols
3408 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3409 work started with create_connection() and timeout in httplib, and
3410 closes patch #723312.
3411
Vinay Sajip8549ce32007-05-06 17:53:37 +00003412- Patch #1676823: Added create_connection() to socket.py, which may be
3413 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003414 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003415

3436
Georg Brandlf66b6032007-03-14 08:27:52 +00003437- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438 AttributeError instead of an IOError when the server's response
3439 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003440
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441- Patch #957650: "%var%" environment variable references are now
3442 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00003445- Patch #1429539: pdb now correctly initializes the __main__ module
3446 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003447 correctly now.
3448
Georg Brandlbad6f192007-03-13 21:32:56 +00003449- The nonobvious commands.getstatus() function is now deprecated.

3455
Georg Brandl3ee81df2008-05-17 18:14:43 +00003456- Patch #1530482: add pydoc.render_doc() which returns the

3467 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003469- Patch #1581073: add a flag to textwrap that prevents the dropping of
3470 whitespace while wrapping.
3471
Georg Brandl92a6bae2007-03-13 17:43:32 +00003472- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003473 are set for invalid interpolation sequences that would lead to
3474 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003475

Collin Winter22c42ba2007-03-10 02:51:26 +00003509

3515

3517 returned string up to the first NUL character.
3518

3528
Georg Brandl3ee81df2008-05-17 18:14:43 +00003529- unittest now verifies more of its assumptions. In particular,
3530 TestCase and TestSuite subclasses (not instances) are no longer
3531 accepted in TestSuite.addTest(). This should cause no
3532 incompatibility since it never made sense with ordinary subclasses
3533 -- the failure just occurred later, with a more cumbersome
3534 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003535

3544
Georg Brandl3ee81df2008-05-17 18:14:43 +00003545- Patch #1673619: setup.py identifies extension modules it doesn't

3905 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3906 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003922- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003923 time so that opening a database previously created with the DB_DUP
3924 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3925 opens. Specifically: dictionary assignment to a DB object will
3926 replace all values for a given key when the database allows
3927 duplicate values. DB users should use DB.put(k, v) when they want
3928 to store duplicates; not DB[k] = v.

3935 characters with ASCII value less than 32. Also, it correctly quotes
3936 dots only if they occur on a single line, as opposed to the previous
3937 behavior of quoting dots if they are the second character of any
3938 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003939
