1077What's New in Python 2.6.1
1078==========================
1079
1080*Release date: 04-Dec-2008*
1081
1082Core and Builtins
1083-----------------
1084
1085- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1086 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1087 instead of throwing a MemoryError.
1088
1089- Issue #4367: Python would segfault during compiling when the unicodedata
1090 module couldn't be imported and \N escapes were present.
1091
1092- Issue #4348: Some bytearray methods returned that didn't cause any change to
1093 the bytearray, returned the same bytearray instead of a copy.
1094
1095- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1096
1097- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1098
1099- Issue #4048: The parser module now correctly validates relative imports.
1100
1101- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1107- Issue #4209: Enabling unicode_literals and the print_function in the same
1108 __future__ import didn't work.
1109
1110- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1111 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1112 really executed because I cannot move to such directory on win2k)
1113
1114- Issue #4069: When set.remove(element) is used with a set element, the element
1115 is temporarily replaced with an equivalent frozenset. But the eventual
1116 KeyError would always report the empty frozenset([]) as the missing key. Now
1117 it correctly refers to the initial element.
1118
1119- Fixed C99 style comments in several files. Python is now C89 compatible
1120 again.

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001269- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1270 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1271 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1272 ``printf`` function, whereas PyString_FromFormat has an independent
1273 implementation and uses "%zd" on all platforms for size_t values.
1274 This makes a difference on win64, where ``printf`` needs "%Id" to display

1370 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1371 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001394- Issue #2975: When compiling several extension modules with Visual Studio 2008
1395 from the same python interpreter, some environment variables would grow
1396 without limit.
1397
Benjamin Peterson37346b22008-08-23 20:27:43 +00001398- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001435What's New in Python 2.6 beta 3?
1436================================
1437
Barry Warsaw07a4a382008-08-21 01:15:08 +00001438*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001439
1440Core and Builtins
1441-----------------
1442
Guido van Rossumf8402962008-08-20 15:01:50 +00001443- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1444 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1445 extensions do not automatically benefit from the class attribute
1446 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1447 to their tp_flags field if they care. This is a backwards
1448 compatibility feature; in 3.0, all types will use the cache by
1449 default.
1450
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001451- Keyword arguments can now follow starred arguments. (``f(a, *args,
1452 keyword=23)`` is now valid syntax.)
1453
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001454- ctypes function pointers that are COM methods have a boolean True
1455 value again.
1456
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001457- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1458 by denying s# to parse objects that have a releasebuffer procedure,
1459 and introducing s*.
1460
Georg Brandl1e13ea92008-08-11 09:07:59 +00001461- Issue #3537: Fix an assertion failure when an empty but presized dict
1462 object was stored in the freelist.
1463
Mark Dickinsonb6467572008-08-04 21:30:09 +00001464- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1465 ValueError consistently across platforms.
1466
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001467- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1468 (64bit Unix, for example), unichr() would truncate its argument and return
1469 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1470
Neal Norwitze7d8be82008-07-31 17:17:14 +00001471- Apply security patches from Apple.
1472
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001473- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1474 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1475
Antoine Pitrou92f82162008-07-25 22:22:08 +00001476- Issue #1819: function calls with several named parameters are now on
1477 average 35% faster (as measured by pybench).
1478
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001479- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1480 the python debugger steps into a class statement: the free variables (local
1481 variables defined in an outer scope) would be deleted from the outer scope.
1482
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001483- Issue #2620: Overflow checking when allocating or reallocating memory
1484 was not always being done properly in some python types and extension
1485 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1486 all been updated to perform better checks and places in the code that
1487 would previously leak memory on the error path when such an allocation
1488 failed have been fixed.

1492
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001493- Issue #3612: Added some missing basic types in ctypes.wintypes.
1494
Benjamin Petersone977ad42008-08-20 01:42:01 +00001495- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1496 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1497
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001498- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1499 version reported by these tools does not necessarily follow the python
1500 version numbering scheme, so the module is less strict when parsing it.
1501
Nick Coghlanf70385a2008-08-18 12:42:46 +00001502- Issue #2235: Added Py3k warnings for types which will become unhashable
1503 under the stricter __hash__ inheritance rules in 3.0. Several types
1504 which did not meet the rules for hash invariants and were already
1505 unhashable in 3.0 have now been explicitly flagged as unhashable in
1506 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1507 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1508
Brett Cannon88f801d2008-08-18 00:46:22 +00001509- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1510 imported into the module but exposed as part of the module's API.
1511
Brett Cannon7b96f072008-08-18 00:41:11 +00001512- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1513
Brett Cannon46225e72008-08-18 00:36:52 +00001514- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1515
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001516- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1517
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001518- Issue #3575: Incremental decoder's decode function now takes bytearray
1519 by using 's*' instead of 't#'.
1520
Jesus Cea585ad8a2009-07-02 15:37:21 +00001521- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001522 fails unicode conversion on 2nd parameter. (windows only)
1523
Facundo Batista94f243a2008-08-17 03:38:39 +00001524- Issue 2464. urllib2 now supports a malformation in the URL received
1525 in a redirect.
1526
Brett Cannonabe423e2008-08-16 21:47:07 +00001527- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001528 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001529
Facundo Batistaeb90b782008-08-16 14:44:07 +00001530- Issue #2776: fixed small issue when handling an URL with double slash
1531 after a 302 response in the case of not going through a proxy.
1532
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001533- Issue #2676: in the email package, content-type parsing was hanging on
1534 pathological input because of quadratic or exponential behaviour of a
1535 regular expression.
1536
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001537- Issue #3476: binary buffered reading through the new "io" library is now
1538 thread-safe.
1539
Brett Cannonbf3157b2008-08-14 05:00:03 +00001540- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1541 since mimetools itself is deprecated. Because modules are cached, all
1542 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1543
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001544- Issue #3134: shutil referenced undefined WindowsError symbol.
1545
Robert Schuppenies14646332008-08-10 11:01:53 +00001546- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1547 menu entries were not deleted.
1548
Brett Cannon83e81842008-08-09 23:30:55 +00001549- Copied the implementation of reduce() to _functools.reduce() to have a
1550 version that did not raise a DeprecationWarning under -3.
1551
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001552- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1553 a MemoryError rather than silently stop the iteration.
1554
Guido van Rossum59ce9012008-08-09 14:55:34 +00001555- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1556 to _sre.compile() will now be rejected. This should not affect anybody
1557 since the re.compile() function never generates invalid re-bytecode.
1558
Skip Montanaroa032bf42008-08-08 22:52:51 +00001559- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1560 upon first access it can be automatically initialized from the csv file if
1561 it wasn't initialized during instantiation.
1562
Brett Cannon3aa2a492008-08-06 22:28:09 +00001563- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1564 the reload() built-in has been removed.
1565
Brett Cannon7e30b672008-08-04 21:52:25 +00001566- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001567 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1570 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1571 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1572 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.

Antoine Pitroude781a42008-08-09 12:43:23 +00001578 asking for a specific length. This problem only affected files opened
1579 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001580
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001581- Issue #3449: Update decimal module to use most recent specification
1582 (v. 1.68) and tests (v. 2.58) from IBM.
1583

1622
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001623- Issue #643841: The language reference now provides more detailed

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001629What's New in Python 2.6 beta 2?
1630================================
1631
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001632*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001634Core and Builtins
1635-----------------
1636
Georg Brandl3e483f62008-07-16 22:57:41 +00001637- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1638 its methods now allow for items objects that can be converted to
1639 an integer using operator.index().
1640
Mark Dickinson64b7e502008-07-16 09:40:03 +00001641- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1642 produced a ValueError instead of giving the correct float.
1643
Eric Smitha5fa5a22008-07-16 00:11:49 +00001644- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1645 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1646
Mark Dickinson7103aa42008-07-15 19:08:33 +00001647- Issue #3008: the float type has a new instance method 'float.hex'
1648 and a new class method 'float.fromhex' to convert floating-point
1649 numbers to and from hexadecimal strings, respectively.
1650
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001651- Issue #2235: __hash__ is once again inherited by default. To allow
1652 collections.Hashable to remain meaningful in the presence of the
1653 default hash implementation (object.__hash__), it is now possible
1654 to explicit block inheritance of hash by setting __hash__=None at
1655 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1656 level.
1657
Nick Coghlanb028f502008-07-13 14:52:36 +00001658- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1659 the parent module cannot be found while performing an absolute import.
1660 This means that an incorrectly defined __package__ attribute will
1661 now only prevent relative imports in that module rather than causing
1662 all imports from that module to fail.
1663
Nick Coghlan14ff9942008-07-08 14:21:42 +00001664- Issue #2517: Allow unicode messages in Exceptions again by correctly
1665 bypassing the instance dictionary when looking up __unicode__ on
1666 new-style classes.

1669 set to a custom object whose write() method happens to install
1670 another file in sys.stdout.
1671
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001672- Issue #3088: Corrected a race condition in classes derived from
1673 threading.local: the first member set by a thread could be saved in
1674 another thread's dictionary.
1675
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001676- Issue #3004: Minor change to slice.indices(): the start and stop
1677 arguments are now treated identically, making the behaviour easier
1678 to describe and understand. For example, slice(None, -10,
1679 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1680 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1681 10, -1).
1682
Georg Brandl278fc502008-07-19 12:46:12 +00001683- Issue #3219: Calling a function with repeated keyword arguments,
1684 f(a=2, a=23), would not cause a syntax error. This was a regression
1685 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001686
Georg Brandl278fc502008-07-19 12:46:12 +00001687- Issue #2862: Make int and float freelist management consistent with
1688 other freelists. Changes their CompactFreeList apis into
1689 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00001694- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
1695 api functions without holding the GIL, which could lead to a fatal
1696 error when they failed.
1697
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001698- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Raymond Hettinger3cd1e422008-07-10 14:03:19 +00001722
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001723- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1724 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001725 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001726 content-length. The problem had been corrected in the 2.4 branch, but never
1727 merged into trunk.
1728

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001742- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1743 handling is now the same as that of other special attributes like __name__).
1744
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001745- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00002197- Issue #1631171: Re-implement the 'warnings' module in C (the
2198 original Python code has been kept as backup). This will allow for
2199 using the 'warning's machinery in such places as the parser where
2200 use of pure Python code is not possible. Both the ``showarning()``
2201 and ``formatwarning()`` gain an optional 'line' argument which is
2202 not called by default for backwards-compatibility reasons. Setting
2203 ``warnings.showwarning()`` to an implementation that lacks support
2204 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002267- Issue #2550: The approach used by client/server code for obtaining
2268 ports to listen on in network-oriented tests has been refined in an
2269 effort to facilitate running multiple instances of the entire
2270 regression test suite in parallel without issue.
2271 test_support.bind_port() has been fixed such that it will always
2272 return a unique port -- which wasn't always the case with the
2273 previous implementation, especially if socket options had been set
2274 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2275 new implementation of bind_port() will actually raise an exception
2276 if it is passed an AF_INET/SOCK_STREAM socket with either the
2277 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2278 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2279 the socket it's been passed. This currently only applies to
2280 Windows. This option prevents any other sockets from binding to the
2281 host/port we've bound to, thus removing the possibility of the
2282 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2283 when a second SOCK_STREAM socket binds and accepts to a host/port
2284 that's already been bound by another socket. The optional preferred
2285 port parameter to bind_port() has been removed. Under no
2286 circumstances should tests be hard coding ports!
2287
2288 test_support.find_unused_port() has also been introduced, which will
2289 pass a temporary socket object to bind_port() in order to obtain an
2290 unused port. The temporary socket object is then closed and
2291 deleted, and the port is returned. This method should only be used
2292 for obtaining an unused port in order to pass to an external program
2293 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2294 a parameter to a server-oriented class that doesn't give you direct
2295 access to the underlying socket used.
2296
2297 Finally, test_support.HOST has been introduced, which should be used
2298 for the host argument of any relevant socket calls (i.e. bind and
2299 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002300
2301 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002302 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002303 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2304 test_asynchat and test_socket_ssl.
2305
Georg Brandl3ee81df2008-05-17 18:14:43 +00002306 It is now possible for multiple instances of the regression test
2307 suite to run in parallel without issue.

2574-----------------
2575
Fred Drakea8ee94b2008-03-01 02:45:07 +00002576- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002577 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002582
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002583- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002584 issue 215555 for a discussion.
2585
Eric Smitha73fbe72008-02-23 03:09:44 +00002586- Added the future_builtins module, which contains hex() and oct().
2587 These are the PEP 3127 version of these functions, designed to be
2588 compatible with the hex() and oct() builtins from Python 3.0. They
2589 differ slightly in their output formats from the existing, unchanged
2590 Python 2.6 builtins. The expected usage of the future_builtins
2591 module is:
2592 from future_builtins import hex, oct
2593
Eric Smith7ef40bf2008-02-20 23:34:22 +00002594- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2595 exponents for exponents with absolute value < 100. Follows C99
2596 standard. This is a change on Windows, which would use 3 digits.
2597 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2598 so that any alterations it does to the resulting string will be
2599 available in stringlib/formatter.h (for float.__format__).
2600
Eric Smith5a3c1352008-02-19 13:21:56 +00002601- Implemented PEP 3101, Advanced String Formatting. This adds a new
2602 builtin format(); a format() method for str and unicode; a
2603 __format__() method to object, str, unicode, int, long, float, and
2604 datetime; the class string.Formatter; and the C API
2605 PyObject_Format().
2606
Georg Brandl3ee81df2008-05-17 18:14:43 +00002607- Fixed several potential crashes, all caused by specially crafted
2608 __del__ methods exploiting objects in temporarily inconsistent
2609 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002610
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002611- Issue #2115: Important speedup in setting __slot__ attributes. Also

2620 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002621
Georg Brandl3ee81df2008-05-17 18:14:43 +00002622- Issue #2045: Fix an infinite recursion triggered when printing a

2627 list was not freed on interpreter shutdown.
2628
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Limit free list of method and builtin function objects to 256

2633 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002634 to compact the internal free lists of pre-allocted ints and floats.
2635
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2637 calls. Python expected the return type int but the fork familie
2638 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002652- Patch #1473257: generator objects gain a gi_code attribute. This is
2653 the same object as the func_code attribute of the function that
2654 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002655
Georg Brandl3ee81df2008-05-17 18:14:43 +00002656- Issue #1920: "while 0" statements were completely removed by the
2657 compiler, even in the presence of an "else" clause, which is
2658 supposed to be run when the condition is false. Now the compiler
2659 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002660

Georg Brandl6caad7d2008-01-26 14:19:22 +00002678- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002679 added.
2680
Christian Heimesc94e2b52008-01-14 04:13:37 +00002681- sys.float_info / PyFloat_GetInfo: The floating point information
2682 object was converted from a dict to a specialized structseq object.
2683
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- Patch #1816: Added sys.flags structseq. It exposes the status of
2685 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002686
Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Objects/structseq.c: Implemented new structseq representation. The
2688 patch makes structseqs (e.g. the return value of os.stat) more
2689 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002690
Georg Brandl3ee81df2008-05-17 18:14:43 +00002691- Patch #1700288: added a type attribute cache that caches method
2692 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002693
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002694- Bug #1776: __import__() no longer accepts filenames on any platform.
2695 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002696
Georg Brandlaed6c662008-01-07 17:25:53 +00002697- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2698
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2700 envvar and sys.dont_write_bytecode attribute. All these can be set
2701 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002702
Georg Brandl3ee81df2008-05-17 18:14:43 +00002703- Improve some exception messages when Windows fails to load an
2704 extension module. Now we get for example '%1 is not a valid Win32
2705 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002706
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002709- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2710 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002711
Christian Heimes0a8143f2007-12-18 23:22:54 +00002712- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002713 and INF. float("nan"), float("inf") and float("-inf") now work on
2714 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002715
Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Compiler now generates simpler and faster code for dictionary
2717 literals. The oparg for BUILD_MAP now indicates an estimated
2718 dictionary size. There is a new opcode, STORE_MAP, for adding
2719 entries to the dictionary.

2737 running, and if the deallocation of its frames somehow calls the
2738 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002739

2744
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Issue #1460: The utf-7 incremental decoder did not accept truncated
2746 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002747
Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Patch #1739468: Directories and zipfiles containing a __main__.py
2749 file can now be directly executed by passing their name to the
2750 interpreter. The directory/zipfile is automatically inserted as the
2751 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002752
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- Issue #1265: Fix a problem with sys.settrace, if the tracing
2754 function uses a generator expression when at the same time the
2755 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002756
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002757- sets and frozensets now have an isdisjoint() method.
2758

2760
Neal Norwitz44f326e2007-10-05 05:29:17 +00002761- Fix warnings found by the new version of the Coverity checker.
2762
Georg Brandl3ee81df2008-05-17 18:14:43 +00002763- The enumerate() builtin function is no longer bounded to sequences
2764 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2765 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002766
Georg Brandl3ee81df2008-05-17 18:14:43 +00002767- Issue #1686386: Tuple's tp_repr did not take into account the
2768 possibility of having a self-referential tuple, which is possible
2769 from C code. Nor did object's tp_str consider that a type's tp_str
2770 could do something that could lead to an inifinite recursion.
2771 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2772 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002773
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774- Issue #1164: It was possible to trigger deadlock when using the
2775 'print' statement to write to a file since the GIL was not released
2776 as needed. Now PyObject_Print() does the right thing along with
2777 various tp_print implementations of the built-in types and those in
2778 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002779
Georg Brandl3ee81df2008-05-17 18:14:43 +00002780- Issue #1147: Exceptions were directly allowing string exceptions in
2781 their throw() method even though string exceptions no longer
2782 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002783
Georg Brandl3ee81df2008-05-17 18:14:43 +00002784- Issue #1096: Prevent a segfault from getting the repr of a very
2785 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002786
Brett Cannon1e534b52007-09-07 04:18:30 +00002787- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002788 PyObject_Call() never calling back out to Python code to trigger
2789 recursion depth updates/checks. Required the creation of a static
2790 RuntimeError instance in case normalizing an exception put the
2791 recursion check value past its limit. Fixes crashers
2792 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002793
Georg Brandl3ee81df2008-05-17 18:14:43 +00002794- Patch #1031213: Decode source line in SyntaxErrors back to its

2798 with %G.
2799
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800- Prevent expandtabs() on string and unicode objects from causing a
2801 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00002807- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808 __*__ attributes. (Some already existed, e.g., __doc__ and
2809 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002810
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002811- Add -3 option to the interpreter to warn about features that are
2812 deprecated and will be changed/removed in Python 3.0.
2813
Georg Brandl2134e752007-05-21 20:34:16 +00002814- Patch #1686487: you can now pass any mapping after '**' in function
2815 calls.
2816
Collin Winter62903052007-05-18 23:11:24 +00002817- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818 "except E as target:". This is to provide forwards compatibility
2819 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002820
Brett Cannon229cee22007-05-05 01:34:02 +00002821- Deprecate BaseException.message as per PEP 352.
2822
Georg Brandl3ee81df2008-05-17 18:14:43 +00002823- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002824 inherited from a builtin base.
2825
Vinay Sajip8549ce32007-05-06 17:53:37 +00002826- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002827 setting a plain string, ie don't expand to single letter identifiers.
2828
Raymond Hettinger13936692007-04-11 18:40:58 +00002829- Request #1191699: Slices can now be pickled.
2830
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002831- Request #1193128: str.translate() now allows a None argument for
2832 translations that only remove characters without re-mapping the
2833 remaining characters.
2834
Georg Brandl5cb76c12007-03-21 09:00:39 +00002835- Patch #1682205: a TypeError while unpacking an iterable is no longer
2836 masked by a generic one with the message "unpack non-sequence".
2837
Neal Norwitzaa754b72007-03-21 06:39:48 +00002838- Remove unused file Python/fmod.c.
2839
Guido van Rossum143b5642007-03-23 04:58:42 +00002840- Bug #1683368: The object.__init__() and object.__new__() methods are
2841 now stricter in rejecting excess arguments. The only time when
2842 either allows excess arguments is when it is not overridden and the
2843 other one is. For backwards compatibility, when both are
2844 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002845 warning later). Also, type.__init__() insists on the same signature
2846 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002847
Georg Brandl3ee81df2008-05-17 18:14:43 +00002848- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2849 object to complex using its __complex__() method before falling back
2850 to the __float__() method. Therefore, the functions in the cmath
2851 module now can operate on objects that define a __complex__()
2852 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002853
Georg Brandl3ee81df2008-05-17 18:14:43 +00002854- Patch #1623563: allow __class__ assignment for classes with
2855 __slots__. The old and the new class are still required to have the
2856 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002857
Georg Brandl3ee81df2008-05-17 18:14:43 +00002858- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Patch #1462488: Python no longer segfaults when
2862 ``object.__reduce_ex__()`` is called with an object that is faking
2863 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002868- Patch #1444529: the builtin compile() now accepts keyword arguments.
2869
Georg Brandl7b9c5552007-03-12 14:30:05 +00002870- Bug #1678647: write a newline after printing an exception in any
2871 case, even when converting the value to a string failed.
2872
Georg Brandl871f1bc2007-03-12 13:17:36 +00002873- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002874 its argument, if it exists. If not, it will work like before. This
2875 allows customizing the output of dir() in the presence of a
2876 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002877
Collin Winter276887b2007-03-12 16:11:39 +00002878- Patch #922167: Python no longer segfaults when faced with infinitely
2879 self-recursive reload() calls (as reported by bug #742342).
2880
Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002884- Patch #1491866: change the complex() constructor to allow
2885 parthensized forms. This means complex(repr(x)) now works instead of
2886 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002887
Georg Brandlaa2321b2007-03-07 00:40:28 +00002888- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002889 makes the filenames the warning module prints much more sensible
2890 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002891
Georg Brandl49aafc92007-03-07 00:34:46 +00002892- Variant of patch #697613: don't exit the interpreter on a SystemExit
2893 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002894 variable is given, but break into the interactive interpreter just
2895 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002903- Patch #1674228: when assigning a slice (old-style), check for the
2904 sq_ass_slice instead of the sq_slice slot.
2905
Georg Brandl3ee81df2008-05-17 18:14:43 +00002906- When printing an unraisable error, don't print exceptions. before
2907 the name. This duplicates the behavior whening normally printing
2908 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002909
Georg Brandl3ee81df2008-05-17 18:14:43 +00002910- Bug #1653736: Properly discard third argument to

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003410- Added a timeout parameter to the constructor of other protocols
3411 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3412 work started with create_connection() and timeout in httplib, and
3413 closes patch #723312.
3414
Vinay Sajip8549ce32007-05-06 17:53:37 +00003415- Patch #1676823: Added create_connection() to socket.py, which may be
3416 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003417 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003418

3439
Georg Brandlf66b6032007-03-14 08:27:52 +00003440- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003441 AttributeError instead of an IOError when the server's response
3442 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003443
Georg Brandl3ee81df2008-05-17 18:14:43 +00003444- Patch #957650: "%var%" environment variable references are now
3445 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00003448- Patch #1429539: pdb now correctly initializes the __main__ module
3449 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003450 correctly now.
3451
Georg Brandlbad6f192007-03-13 21:32:56 +00003452- The nonobvious commands.getstatus() function is now deprecated.

3458
Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Patch #1530482: add pydoc.render_doc() which returns the
3460 documentation for a thing instead of paging it to stdout, which

3469 parameter which can be set to False to prevent the default
3470 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003471
Georg Brandl9e6b4702007-03-13 18:15:41 +00003472- Patch #1581073: add a flag to textwrap that prevents the dropping of
3473 whitespace while wrapping.
3474
Georg Brandl92a6bae2007-03-13 17:43:32 +00003475- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003476 are set for invalid interpolation sequences that would lead to
3477 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003478

Georg Brandl3ee81df2008-05-17 18:14:43 +00003493 field names in its exception message if you try to write a record
3494 with a dictionary containing fields not in the CSV field names list.

3517 Python would crash instead of raising an error.
3518

3520 returned string up to the first NUL character.
3521

3531
Georg Brandl3ee81df2008-05-17 18:14:43 +00003532- unittest now verifies more of its assumptions. In particular,
3533 TestCase and TestSuite subclasses (not instances) are no longer
3534 accepted in TestSuite.addTest(). This should cause no
3535 incompatibility since it never made sense with ordinary subclasses
3536 -- the failure just occurred later, with a more cumbersome
3537 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003538

3546 given a unicode argument and os.listdir() returns unicode filenames.
3547
Georg Brandl3ee81df2008-05-17 18:14:43 +00003548- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003907- Marshal.dumps() now expects exact type matches for int, long, float,
3908 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3909 silently miscode subclasses of those types. Now, it raises a

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003925- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00003926 time so that opening a database previously created with the DB_DUP
3927 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3928 opens. Specifically: dictionary assignment to a DB object will
3929 replace all values for a given key when the database allows
3930 duplicate values. DB users should use DB.put(k, v) when they want
3931 to store duplicates; not DB[k] = v.

3938 characters with ASCII value less than 32. Also, it correctly quotes
3939 dots only if they occur on a single line, as opposed to the previous
3940 behavior of quoting dots if they are the second character of any
3941 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003942
