84
Tarek Ziadé06426fc2010-01-11 22:54:57 +000085- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

97 renaming of `cPickle` to `pickle`. The warning was annoying since there's
98 no alternative to cPickle if you care about performance. Patch by Florent
99 Xicluna.
100
Antoine Pitrou8dba7272010-01-07 18:04:12 +0000101- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000137- Issue #7318: multiprocessing now uses a timeout when it fails to establish

158 reading from stdin so that existing input does not confuse it and
159 lead to incorrect entry or an IOError. It also properly flushes it

170
R. David Murray7034db32009-10-27 23:39:06 +0000171- Issue #7082: When falling back to the MIME 'name' parameter, the
172 correct place to look for it is the Content-Type header.
173
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000174- Issue #7099: Decimal.is_normal now returns True for numbers with exponent

Vinay Sajip6badbe92009-01-20 22:49:13 +0000713- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000714 method on file objects with closefd=False. The file descriptor is still
715 kept open but the file object behaves like a closed file. The ``FileIO``
716 object also got a new readonly attribute ``closefd``.
717
Georg Brandlfa71a902008-12-05 09:08:28 +0000718- Issue #3689: The list reversed iterator now supports __length_hint__

924 302 conformant loader) will now work correctly in most cases (they
925 are still subject to the constraints that exist for all code running

1085What's New in Python 2.6.1
1086==========================
1087
1088*Release date: 04-Dec-2008*
1089
1090Core and Builtins
1091-----------------
1092
1093- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1094 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1095 instead of throwing a MemoryError.
1096
1097- Issue #4367: Python would segfault during compiling when the unicodedata
1098 module couldn't be imported and \N escapes were present.
1099
1100- Issue #4348: Some bytearray methods returned that didn't cause any change to
1101 the bytearray, returned the same bytearray instead of a copy.
1102
1103- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1104
1105- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1106
1107- Issue #4048: The parser module now correctly validates relative imports.
1108
1109- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1114
1115- Issue #4209: Enabling unicode_literals and the print_function in the same
1116 __future__ import didn't work.
1117
1118- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1119 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1120 really executed because I cannot move to such directory on win2k)
1121
1122- Issue #4069: When set.remove(element) is used with a set element, the element
1123 is temporarily replaced with an equivalent frozenset. But the eventual
1124 KeyError would always report the empty frozenset([]) as the missing key. Now
1125 it correctly refers to the initial element.
1126
1127- Fixed C99 style comments in several files. Python is now C89 compatible
1128 again.

1279 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1280 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitrou0668c622008-08-26 22:42:08 +00001303 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1304 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1305 when given a tuple of classes as second argument, were looking up
1306 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1307 type object.
1308
Neal Norwitz18aa3882008-08-24 05:04:52 +00001309- Fix crashes on memory allocation failure found with failmalloc.

1378 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1379 for catch_warnings() also led to an improvement in the raising of a

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001402- Issue #2975: When compiling several extension modules with Visual Studio 2008
1403 from the same python interpreter, some environment variables would grow
1404 without limit.
1405

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001443What's New in Python 2.6 beta 3?
1444================================
1445
Barry Warsaw07a4a382008-08-21 01:15:08 +00001446*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001447
1448Core and Builtins
1449-----------------
1450
Guido van Rossumf8402962008-08-20 15:01:50 +00001451- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1452 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1453 extensions do not automatically benefit from the class attribute
1454 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1455 to their tp_flags field if they care. This is a backwards
1456 compatibility feature; in 3.0, all types will use the cache by
1457 default.
1458
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001459- Keyword arguments can now follow starred arguments. (``f(a, *args,
1460 keyword=23)`` is now valid syntax.)
1461
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001462- ctypes function pointers that are COM methods have a boolean True
1463 value again.
1464
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001465- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1466 by denying s# to parse objects that have a releasebuffer procedure,
1467 and introducing s*.
1468
Georg Brandl1e13ea92008-08-11 09:07:59 +00001469- Issue #3537: Fix an assertion failure when an empty but presized dict
1470 object was stored in the freelist.
1471
Mark Dickinsonb6467572008-08-04 21:30:09 +00001472- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1473 ValueError consistently across platforms.
1474
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001475- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1476 (64bit Unix, for example), unichr() would truncate its argument and return
1477 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1478
Neal Norwitze7d8be82008-07-31 17:17:14 +00001479- Apply security patches from Apple.
1480
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001481- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1482 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1483
Antoine Pitrou92f82162008-07-25 22:22:08 +00001484- Issue #1819: function calls with several named parameters are now on
1485 average 35% faster (as measured by pybench).
1486
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001487- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1488 the python debugger steps into a class statement: the free variables (local
1489 variables defined in an outer scope) would be deleted from the outer scope.
1490
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001491- Issue #2620: Overflow checking when allocating or reallocating memory
1492 was not always being done properly in some python types and extension
1493 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1494 all been updated to perform better checks and places in the code that
1495 would previously leak memory on the error path when such an allocation
1496 failed have been fixed.

1500
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001501- Issue #3612: Added some missing basic types in ctypes.wintypes.
1502
Benjamin Petersone977ad42008-08-20 01:42:01 +00001503- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1504 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1505
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001506- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1507 version reported by these tools does not necessarily follow the python
1508 version numbering scheme, so the module is less strict when parsing it.
1509
Nick Coghlanf70385a2008-08-18 12:42:46 +00001510- Issue #2235: Added Py3k warnings for types which will become unhashable
1511 under the stricter __hash__ inheritance rules in 3.0. Several types
1512 which did not meet the rules for hash invariants and were already
1513 unhashable in 3.0 have now been explicitly flagged as unhashable in
1514 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1515 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1516
Brett Cannon88f801d2008-08-18 00:46:22 +00001517- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1518 imported into the module but exposed as part of the module's API.
1519
Brett Cannon7b96f072008-08-18 00:41:11 +00001520- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1521
Brett Cannon46225e72008-08-18 00:36:52 +00001522- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1523
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001524- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1525
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001526- Issue #3575: Incremental decoder's decode function now takes bytearray
1527 by using 's*' instead of 't#'.
1528
Jesus Cea585ad8a2009-07-02 15:37:21 +00001529- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001530 fails unicode conversion on 2nd parameter. (windows only)
1531
Facundo Batista94f243a2008-08-17 03:38:39 +00001532- Issue 2464. urllib2 now supports a malformation in the URL received
1533 in a redirect.
1534
Brett Cannonabe423e2008-08-16 21:47:07 +00001535- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001536 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001537
Facundo Batistaeb90b782008-08-16 14:44:07 +00001538- Issue #2776: fixed small issue when handling an URL with double slash
1539 after a 302 response in the case of not going through a proxy.
1540
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001541- Issue #2676: in the email package, content-type parsing was hanging on
1542 pathological input because of quadratic or exponential behaviour of a
1543 regular expression.
1544
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001545- Issue #3476: binary buffered reading through the new "io" library is now
1546 thread-safe.
1547
Brett Cannonbf3157b2008-08-14 05:00:03 +00001548- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1549 since mimetools itself is deprecated. Because modules are cached, all
1550 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1551
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001552- Issue #3134: shutil referenced undefined WindowsError symbol.
1553
Robert Schuppenies14646332008-08-10 11:01:53 +00001554- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1555 menu entries were not deleted.
1556
Brett Cannon83e81842008-08-09 23:30:55 +00001557- Copied the implementation of reduce() to _functools.reduce() to have a
1558 version that did not raise a DeprecationWarning under -3.
1559
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001560- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1561 a MemoryError rather than silently stop the iteration.
1562
Guido van Rossum59ce9012008-08-09 14:55:34 +00001563- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1564 to _sre.compile() will now be rejected. This should not affect anybody
1565 since the re.compile() function never generates invalid re-bytecode.
1566
Skip Montanaroa032bf42008-08-08 22:52:51 +00001567- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1568 upon first access it can be automatically initialized from the csv file if
1569 it wasn't initialized during instantiation.
1570
Brett Cannon3aa2a492008-08-06 22:28:09 +00001571- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1572 the reload() built-in has been removed.
1573
Brett Cannon7e30b672008-08-04 21:52:25 +00001574- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001575 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

1578 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1579 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1580 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001581

Antoine Pitroude781a42008-08-09 12:43:23 +00001586 asking for a specific length. This problem only affected files opened

1639
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001640*Release date: 17-Jul-2008*

1643-----------------
1644
Georg Brandl3e483f62008-07-16 22:57:41 +00001645- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1646 its methods now allow for items objects that can be converted to
1647 an integer using operator.index().
1648
Mark Dickinson64b7e502008-07-16 09:40:03 +00001649- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1650 produced a ValueError instead of giving the correct float.
1651
Eric Smitha5fa5a22008-07-16 00:11:49 +00001652- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1653 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1654
Mark Dickinson7103aa42008-07-15 19:08:33 +00001655- Issue #3008: the float type has a new instance method 'float.hex'
1656 and a new class method 'float.fromhex' to convert floating-point
1657 numbers to and from hexadecimal strings, respectively.
1658
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001659- Issue #2235: __hash__ is once again inherited by default. To allow
1660 collections.Hashable to remain meaningful in the presence of the
1661 default hash implementation (object.__hash__), it is now possible
1662 to explicit block inheritance of hash by setting __hash__=None at
1663 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1664 level.
1665
Nick Coghlanb028f502008-07-13 14:52:36 +00001666- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1667 the parent module cannot be found while performing an absolute import.
1668 This means that an incorrectly defined __package__ attribute will
1669 now only prevent relative imports in that module rather than causing
1670 all imports from that module to fail.
1671
Nick Coghlan14ff9942008-07-08 14:21:42 +00001672- Issue #2517: Allow unicode messages in Exceptions again by correctly

1681 threading.local: the first member set by a thread could be saved in
1682 another thread's dictionary.
1683
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001684- Issue #3004: Minor change to slice.indices(): the start and stop
1685 arguments are now treated identically, making the behaviour easier
1686 to describe and understand. For example, slice(None, -10,
1687 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1688 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1689 10, -1).
1690
Georg Brandl278fc502008-07-19 12:46:12 +00001691- Issue #3219: Calling a function with repeated keyword arguments,
1692 f(a=2, a=23), would not cause a syntax error. This was a regression
1693 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001694
Georg Brandl278fc502008-07-19 12:46:12 +00001695- Issue #2862: Make int and float freelist management consistent with
1696 other freelists. Changes their CompactFreeList apis into
1697 ClearFreeList apis and calls them via gc.collect().

1704 error when they failed.
1705
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001706- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001731- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1732 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001733 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001734 content-length. The problem had been corrected in the 2.4 branch, but never
1735 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001750- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1751 handling is now the same as that of other special attributes like __name__).

2163- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002164
2165- The PyString functions have been renamed to PyBytes. A batch of
2166 defines were added so that the linker still sees the original
2167 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002205- Issue #1631171: Re-implement the 'warnings' module in C (the
2206 original Python code has been kept as backup). This will allow for
2207 using the 'warning's machinery in such places as the parser where
2208 use of pure Python code is not possible. Both the ``showarning()``
2209 and ``formatwarning()`` gain an optional 'line' argument which is
2210 not called by default for backwards-compatibility reasons. Setting
2211 ``warnings.showwarning()`` to an implementation that lacks support
2212 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002254- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002255 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002275- Issue #2550: The approach used by client/server code for obtaining
2276 ports to listen on in network-oriented tests has been refined in an
2277 effort to facilitate running multiple instances of the entire
2278 regression test suite in parallel without issue.
2279 test_support.bind_port() has been fixed such that it will always
2280 return a unique port -- which wasn't always the case with the
2281 previous implementation, especially if socket options had been set
2282 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2283 new implementation of bind_port() will actually raise an exception
2284 if it is passed an AF_INET/SOCK_STREAM socket with either the
2285 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2286 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2287 the socket it's been passed. This currently only applies to
2288 Windows. This option prevents any other sockets from binding to the
2289 host/port we've bound to, thus removing the possibility of the
2290 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2291 when a second SOCK_STREAM socket binds and accepts to a host/port
2292 that's already been bound by another socket. The optional preferred
2293 port parameter to bind_port() has been removed. Under no
2294 circumstances should tests be hard coding ports!
2295
2296 test_support.find_unused_port() has also been introduced, which will
2297 pass a temporary socket object to bind_port() in order to obtain an
2298 unused port. The temporary socket object is then closed and
2299 deleted, and the port is returned. This method should only be used
2300 for obtaining an unused port in order to pass to an external program
2301 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2302 a parameter to a server-oriented class that doesn't give you direct
2303 access to the underlying socket used.
2304
2305 Finally, test_support.HOST has been introduced, which should be used
2306 for the host argument of any relevant socket calls (i.e. bind and
2307 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002308
2309 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002310 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002311 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2312 test_asynchat and test_socket_ssl.
2313
Georg Brandl3ee81df2008-05-17 18:14:43 +00002314 It is now possible for multiple instances of the regression test
2315 suite to run in parallel without issue.

2583
Fred Drakea8ee94b2008-03-01 02:45:07 +00002584- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002585 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002590
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002591- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002592 issue 215555 for a discussion.
2593
Eric Smitha73fbe72008-02-23 03:09:44 +00002594- Added the future_builtins module, which contains hex() and oct().
2595 These are the PEP 3127 version of these functions, designed to be
2596 compatible with the hex() and oct() builtins from Python 3.0. They
2597 differ slightly in their output formats from the existing, unchanged
2598 Python 2.6 builtins. The expected usage of the future_builtins
2599 module is:
2600 from future_builtins import hex, oct
2601
Eric Smith7ef40bf2008-02-20 23:34:22 +00002602- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2603 exponents for exponents with absolute value < 100. Follows C99
2604 standard. This is a change on Windows, which would use 3 digits.
2605 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2606 so that any alterations it does to the resulting string will be
2607 available in stringlib/formatter.h (for float.__format__).
2608
Eric Smith5a3c1352008-02-19 13:21:56 +00002609- Implemented PEP 3101, Advanced String Formatting. This adds a new
2610 builtin format(); a format() method for str and unicode; a
2611 __format__() method to object, str, unicode, int, long, float, and
2612 datetime; the class string.Formatter; and the C API
2613 PyObject_Format().
2614
Georg Brandl3ee81df2008-05-17 18:14:43 +00002615- Fixed several potential crashes, all caused by specially crafted
2616 __del__ methods exploiting objects in temporarily inconsistent
2617 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002618
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002619- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002620 prevent a possible crash: an Abstract Base Class would try to access
2621 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002622

Georg Brandl3ee81df2008-05-17 18:14:43 +00002626- Clear all free lists during a gc.collect() of the highest generation
2627 in order to allow pymalloc to free more arenas. Python may give back
2628 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002629
Georg Brandl3ee81df2008-05-17 18:14:43 +00002630- Issue #2045: Fix an infinite recursion triggered when printing a
2631 subclass of collections.defaultdict, if its default_factory is set
2632 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002633
Christian Heimesf75dbef2008-02-08 00:11:31 +00002634- Fixed a minor memory leak in dictobject.c. The content of the free
2635 list was not freed on interpreter shutdown.
2636
Georg Brandl3ee81df2008-05-17 18:14:43 +00002637- Limit free list of method and builtin function objects to 256
2638 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002640- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2641 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002642 to compact the internal free lists of pre-allocted ints and floats.
2643
Georg Brandl3ee81df2008-05-17 18:14:43 +00002644- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2645 calls. Python expected the return type int but the fork familie
2646 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002647
Georg Brandl3ee81df2008-05-17 18:14:43 +00002648- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002660- Patch #1473257: generator objects gain a gi_code attribute. This is
2661 the same object as the func_code attribute of the function that
2662 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Issue #1920: "while 0" statements were completely removed by the
2665 compiler, even in the presence of an "else" clause, which is
2666 supposed to be run when the condition is false. Now the compiler
2667 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002668
Guido van Rossumeead05f2008-01-24 18:21:02 +00002669- A few crashers fixed: weakref_in_del.py (issue #1377858);

Christian Heimes082c9b02008-01-23 14:20:50 +00002678 several extension methods and modules do not work without unicode
2679 support.
2680
Georg Brandl26543b12008-01-21 18:36:51 +00002681- Issue #1882: when compiling code from a string, encoding cookies in the
2682 second line of code were not always recognized correctly.
2683
Georg Brandl14404b62008-01-19 19:27:05 +00002684- Issue #1679: "0x" was taken as a valid integer literal.
2685
Georg Brandl6caad7d2008-01-26 14:19:22 +00002686- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002687 added.
2688
Christian Heimesc94e2b52008-01-14 04:13:37 +00002689- sys.float_info / PyFloat_GetInfo: The floating point information
2690 object was converted from a dict to a specialized structseq object.
2691
Georg Brandl3ee81df2008-05-17 18:14:43 +00002692- Patch #1816: Added sys.flags structseq. It exposes the status of
2693 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Objects/structseq.c: Implemented new structseq representation. The
2696 patch makes structseqs (e.g. the return value of os.stat) more
2697 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002698
Georg Brandl3ee81df2008-05-17 18:14:43 +00002699- Patch #1700288: added a type attribute cache that caches method
2700 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002701
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002702- Bug #1776: __import__() no longer accepts filenames on any platform.
2703 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002704
Georg Brandlaed6c662008-01-07 17:25:53 +00002705- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2706
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2708 envvar and sys.dont_write_bytecode attribute. All these can be set
2709 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002710
Georg Brandl3ee81df2008-05-17 18:14:43 +00002711- Improve some exception messages when Windows fails to load an
2712 extension module. Now we get for example '%1 is not a valid Win32
2713 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002714
Georg Brandl3ee81df2008-05-17 18:14:43 +00002715- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002717- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2718 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002719
Christian Heimes0a8143f2007-12-18 23:22:54 +00002720- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002721 and INF. float("nan"), float("inf") and float("-inf") now work on
2722 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002723
Georg Brandl3ee81df2008-05-17 18:14:43 +00002724- Compiler now generates simpler and faster code for dictionary
2725 literals. The oparg for BUILD_MAP now indicates an estimated
2726 dictionary size. There is a new opcode, STORE_MAP, for adding
2727 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002737- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002738 SystemError.
2739
Nick Coghlanef01d822007-12-03 12:55:17 +00002740- PEP 366: Allow explicit relative imports when executing modules

2745 running, and if the deallocation of its frames somehow calls the
2746 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002747

2752
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- Issue #1460: The utf-7 incremental decoder did not accept truncated
2754 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002755
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756- Patch #1739468: Directories and zipfiles containing a __main__.py
2757 file can now be directly executed by passing their name to the
2758 interpreter. The directory/zipfile is automatically inserted as the
2759 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002760
Georg Brandl3ee81df2008-05-17 18:14:43 +00002761- Issue #1265: Fix a problem with sys.settrace, if the tracing
2762 function uses a generator expression when at the same time the
2763 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002764
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002765- sets and frozensets now have an isdisjoint() method.
2766
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002767- optimize the performance of builtin.sum().
2768
Neal Norwitz44f326e2007-10-05 05:29:17 +00002769- Fix warnings found by the new version of the Coverity checker.
2770
Georg Brandl3ee81df2008-05-17 18:14:43 +00002771- The enumerate() builtin function is no longer bounded to sequences
2772 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2773 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002774
Georg Brandl3ee81df2008-05-17 18:14:43 +00002775- Issue #1686386: Tuple's tp_repr did not take into account the
2776 possibility of having a self-referential tuple, which is possible
2777 from C code. Nor did object's tp_str consider that a type's tp_str
2778 could do something that could lead to an inifinite recursion.
2779 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2780 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- Issue #1164: It was possible to trigger deadlock when using the
2783 'print' statement to write to a file since the GIL was not released
2784 as needed. Now PyObject_Print() does the right thing along with
2785 various tp_print implementations of the built-in types and those in
2786 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002787
Georg Brandl3ee81df2008-05-17 18:14:43 +00002788- Issue #1147: Exceptions were directly allowing string exceptions in
2789 their throw() method even though string exceptions no longer
2790 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002791
Georg Brandl3ee81df2008-05-17 18:14:43 +00002792- Issue #1096: Prevent a segfault from getting the repr of a very
2793 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002794
Brett Cannon1e534b52007-09-07 04:18:30 +00002795- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796 PyObject_Call() never calling back out to Python code to trigger
2797 recursion depth updates/checks. Required the creation of a static
2798 RuntimeError instance in case normalizing an exception put the
2799 recursion check value past its limit. Fixes crashers
2800 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002801
Georg Brandl3ee81df2008-05-17 18:14:43 +00002802- Patch #1031213: Decode source line in SyntaxErrors back to its

2806 with %G.
2807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Prevent expandtabs() on string and unicode objects from causing a
2809 segfault when a large width is passed on 32-bit platforms.

Georg Brandla5ea6892007-06-01 11:33:33 +00002814
Neal Norwitz0ac60192007-05-27 04:08:54 +00002815- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002816 __*__ attributes. (Some already existed, e.g., __doc__ and
2817 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002818
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002819- Add -3 option to the interpreter to warn about features that are
2820 deprecated and will be changed/removed in Python 3.0.
2821
Georg Brandl2134e752007-05-21 20:34:16 +00002822- Patch #1686487: you can now pass any mapping after '**' in function
2823 calls.
2824
Collin Winter62903052007-05-18 23:11:24 +00002825- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002826 "except E as target:". This is to provide forwards compatibility
2827 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002828
Brett Cannon229cee22007-05-05 01:34:02 +00002829- Deprecate BaseException.message as per PEP 352.
2830
Georg Brandl3ee81df2008-05-17 18:14:43 +00002831- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002832 inherited from a builtin base.
2833
Vinay Sajip8549ce32007-05-06 17:53:37 +00002834- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002835 setting a plain string, ie don't expand to single letter identifiers.
2836
Raymond Hettinger13936692007-04-11 18:40:58 +00002837- Request #1191699: Slices can now be pickled.
2838
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002839- Request #1193128: str.translate() now allows a None argument for
2840 translations that only remove characters without re-mapping the
2841 remaining characters.
2842
Georg Brandl5cb76c12007-03-21 09:00:39 +00002843- Patch #1682205: a TypeError while unpacking an iterable is no longer
2844 masked by a generic one with the message "unpack non-sequence".
2845
Neal Norwitzaa754b72007-03-21 06:39:48 +00002846- Remove unused file Python/fmod.c.
2847
Guido van Rossum143b5642007-03-23 04:58:42 +00002848- Bug #1683368: The object.__init__() and object.__new__() methods are
2849 now stricter in rejecting excess arguments. The only time when
2850 either allows excess arguments is when it is not overridden and the
2851 other one is. For backwards compatibility, when both are
2852 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002853 warning later). Also, type.__init__() insists on the same signature
2854 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2857 object to complex using its __complex__() method before falling back
2858 to the __float__() method. Therefore, the functions in the cmath
2859 module now can operate on objects that define a __complex__()
2860 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002861
Georg Brandl3ee81df2008-05-17 18:14:43 +00002862- Patch #1623563: allow __class__ assignment for classes with
2863 __slots__. The old and the new class are still required to have the
2864 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002865
Georg Brandl3ee81df2008-05-17 18:14:43 +00002866- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002869- Patch #1462488: Python no longer segfaults when
2870 ``object.__reduce_ex__()`` is called with an object that is faking
2871 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002872
Georg Brandl3ee81df2008-05-17 18:14:43 +00002873- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002876- Patch #1444529: the builtin compile() now accepts keyword arguments.
2877
Georg Brandl7b9c5552007-03-12 14:30:05 +00002878- Bug #1678647: write a newline after printing an exception in any
2879 case, even when converting the value to a string failed.
2880
Georg Brandl871f1bc2007-03-12 13:17:36 +00002881- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882 its argument, if it exists. If not, it will work like before. This
2883 allows customizing the output of dir() in the presence of a
2884 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002885
Collin Winter276887b2007-03-12 16:11:39 +00002886- Patch #922167: Python no longer segfaults when faced with infinitely
2887 self-recursive reload() calls (as reported by bug #742342).
2888
Georg Brandl3ee81df2008-05-17 18:14:43 +00002889- Patch #1675981: remove unreachable code from ``type.__new__()``
2890 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00002891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Patch #1491866: change the complex() constructor to allow
2893 parthensized forms. This means complex(repr(x)) now works instead of
2894 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002895
Georg Brandlaa2321b2007-03-07 00:40:28 +00002896- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002897 makes the filenames the warning module prints much more sensible
2898 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002899
Georg Brandl49aafc92007-03-07 00:34:46 +00002900- Variant of patch #697613: don't exit the interpreter on a SystemExit
2901 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002902 variable is given, but break into the interactive interpreter just
2903 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00002910
Georg Brandl0fca97a2007-03-05 22:28:08 +00002911- Patch #1674228: when assigning a slice (old-style), check for the
2912 sq_ass_slice instead of the sq_slice slot.
2913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- When printing an unraisable error, don't print exceptions. before
2915 the name. This duplicates the behavior whening normally printing
2916 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002917

Facundo Batistad918a652007-04-24 13:54:38 +00003407- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003408 the client's request was successfully received, understood, and
3409 accepted. Now in these cases no error is raised in urllib (issue
3410 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003418- Added a timeout parameter to the constructor of other protocols
3419 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3420 work started with create_connection() and timeout in httplib, and
3421 closes patch #723312.
3422
Vinay Sajip8549ce32007-05-06 17:53:37 +00003423- Patch #1676823: Added create_connection() to socket.py, which may be
3424 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003425 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003426

3447
Georg Brandlf66b6032007-03-14 08:27:52 +00003448- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003449 AttributeError instead of an IOError when the server's response
3450 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003451

Georg Brandl3ee81df2008-05-17 18:14:43 +00003456- Patch #1429539: pdb now correctly initializes the __main__ module
3457 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003458 correctly now.
3459

Georg Brandl3ee81df2008-05-17 18:14:43 +00003467- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00003480- Patch #1581073: add a flag to textwrap that prevents the dropping of
3481 whitespace while wrapping.
3482
Georg Brandl92a6bae2007-03-13 17:43:32 +00003483- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003484 are set for invalid interpolation sequences that would lead to
3485 errors on reading back those values.

3528 returned string up to the first NUL character.
3529

3539
Georg Brandl3ee81df2008-05-17 18:14:43 +00003540- unittest now verifies more of its assumptions. In particular,
3541 TestCase and TestSuite subclasses (not instances) are no longer
3542 accepted in TestSuite.addTest(). This should cause no
3543 incompatibility since it never made sense with ordinary subclasses
3544 -- the failure just occurred later, with a more cumbersome
3545 exception.

3554 given a unicode argument and os.listdir() returns unicode filenames.
3555
Georg Brandl3ee81df2008-05-17 18:14:43 +00003556- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003934 time so that opening a database previously created with the DB_DUP
3935 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3936 opens. Specifically: dictionary assignment to a DB object will
3937 replace all values for a given key when the database allows
3938 duplicate values. DB users should use DB.put(k, v) when they want
3939 to store duplicates; not DB[k] = v.

3946 characters with ASCII value less than 32. Also, it correctly quotes
3947 dots only if they occur on a single line, as opposed to the previous
3948 behavior of quoting dots if they are the second character of any
3949 line.
