83
Tarek Ziadé06426fc2010-01-11 22:54:57 +000084- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

94
Antoine Pitrou0b074572010-01-08 19:21:34 +000095- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
96 renaming of `cPickle` to `pickle`. The warning was annoying since there's

135
Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000136- Issue #7318: multiprocessing now uses a timeout when it fails to establish

155

157 reading from stdin so that existing input does not confuse it and
158 lead to incorrect entry or an IOError. It also properly flushes it
159 afterwards to avoid the terminal echoing the input afterwards on
160 OSes such as Solaris.
161
Raymond Hettinger80d49b32009-11-01 08:53:21 +0000162- Issue #7244: itertools.izip_longest() no longer ignores exceptions

169
R. David Murray7034db32009-10-27 23:39:06 +0000170- Issue #7082: When falling back to the MIME 'name' parameter, the

172

180 is too large to fit in the current precision.
181

Vinay Sajip6badbe92009-01-20 22:49:13 +0000712- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()``
Georg Brandld2094602008-12-05 08:51:30 +0000713 method on file objects with closefd=False. The file descriptor is still
714 kept open but the file object behaves like a closed file. The ``FileIO``
715 object also got a new readonly attribute ``closefd``.
716
Georg Brandlfa71a902008-12-05 09:08:28 +0000717- Issue #3689: The list reversed iterator now supports __length_hint__

923 302 conformant loader) will now work correctly in most cases (they
924 are still subject to the constraints that exist for all code running

1084What's New in Python 2.6.1
1085==========================
1086
1087*Release date: 04-Dec-2008*
1088
1089Core and Builtins
1090-----------------
1091
1092- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1093 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1094 instead of throwing a MemoryError.
1095
1096- Issue #4367: Python would segfault during compiling when the unicodedata
1097 module couldn't be imported and \N escapes were present.
1098
1099- Issue #4348: Some bytearray methods returned that didn't cause any change to
1100 the bytearray, returned the same bytearray instead of a copy.
1101
1102- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1103
1104- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1105
1106- Issue #4048: The parser module now correctly validates relative imports.
1107
1108- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

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

1278 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1279 ``printf`` function, whereas PyString_FromFormat has an independent

Antoine Pitrou0668c622008-08-26 22:42:08 +00001302 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1303 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1304 when given a tuple of classes as second argument, were looking up
1305 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1306 type object.
1307
Neal Norwitz18aa3882008-08-24 05:04:52 +00001308- Fix crashes on memory allocation failure found with failmalloc.

1377 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1378 for catch_warnings() also led to an improvement in the raising of a
1379 DeprecationWarning related to warnings.warn_explicit().

1402 from the same python interpreter, some environment variables would grow
1403 without limit.
1404

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001442What's New in Python 2.6 beta 3?
1443================================
1444
Barry Warsaw07a4a382008-08-21 01:15:08 +00001445*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001446
1447Core and Builtins
1448-----------------
1449
Guido van Rossumf8402962008-08-20 15:01:50 +00001450- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1451 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1452 extensions do not automatically benefit from the class attribute
1453 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1454 to their tp_flags field if they care. This is a backwards
1455 compatibility feature; in 3.0, all types will use the cache by
1456 default.
1457
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001458- Keyword arguments can now follow starred arguments. (``f(a, *args,
1459 keyword=23)`` is now valid syntax.)
1460
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001461- ctypes function pointers that are COM methods have a boolean True
1462 value again.
1463
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001464- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1465 by denying s# to parse objects that have a releasebuffer procedure,
1466 and introducing s*.
1467
Georg Brandl1e13ea92008-08-11 09:07:59 +00001468- Issue #3537: Fix an assertion failure when an empty but presized dict
1469 object was stored in the freelist.
1470
Mark Dickinsonb6467572008-08-04 21:30:09 +00001471- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1472 ValueError consistently across platforms.
1473
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001474- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1475 (64bit Unix, for example), unichr() would truncate its argument and return
1476 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1477
Neal Norwitze7d8be82008-07-31 17:17:14 +00001478- Apply security patches from Apple.
1479
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001480- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1481 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1482
Antoine Pitrou92f82162008-07-25 22:22:08 +00001483- Issue #1819: function calls with several named parameters are now on
1484 average 35% faster (as measured by pybench).
1485
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001486- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1487 the python debugger steps into a class statement: the free variables (local
1488 variables defined in an outer scope) would be deleted from the outer scope.
1489
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001490- Issue #2620: Overflow checking when allocating or reallocating memory
1491 was not always being done properly in some python types and extension
1492 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1493 all been updated to perform better checks and places in the code that
1494 would previously leak memory on the error path when such an allocation
1495 failed have been fixed.

1499
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001500- Issue #3612: Added some missing basic types in ctypes.wintypes.
1501
Benjamin Petersone977ad42008-08-20 01:42:01 +00001502- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1503 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1504
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001505- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1506 version reported by these tools does not necessarily follow the python
1507 version numbering scheme, so the module is less strict when parsing it.
1508
Nick Coghlanf70385a2008-08-18 12:42:46 +00001509- Issue #2235: Added Py3k warnings for types which will become unhashable
1510 under the stricter __hash__ inheritance rules in 3.0. Several types
1511 which did not meet the rules for hash invariants and were already
1512 unhashable in 3.0 have now been explicitly flagged as unhashable in
1513 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1514 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1515
Brett Cannon88f801d2008-08-18 00:46:22 +00001516- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1517 imported into the module but exposed as part of the module's API.
1518
Brett Cannon7b96f072008-08-18 00:41:11 +00001519- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1520
Brett Cannon46225e72008-08-18 00:36:52 +00001521- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001523- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1524
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001525- Issue #3575: Incremental decoder's decode function now takes bytearray
1526 by using 's*' instead of 't#'.
1527
Jesus Cea585ad8a2009-07-02 15:37:21 +00001528- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001529 fails unicode conversion on 2nd parameter. (windows only)
1530
Facundo Batista94f243a2008-08-17 03:38:39 +00001531- Issue 2464. urllib2 now supports a malformation in the URL received
1532 in a redirect.
1533
Brett Cannonabe423e2008-08-16 21:47:07 +00001534- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001535 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001536
Facundo Batistaeb90b782008-08-16 14:44:07 +00001537- Issue #2776: fixed small issue when handling an URL with double slash
1538 after a 302 response in the case of not going through a proxy.
1539
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001540- Issue #2676: in the email package, content-type parsing was hanging on
1541 pathological input because of quadratic or exponential behaviour of a
1542 regular expression.
1543
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001544- Issue #3476: binary buffered reading through the new "io" library is now
1545 thread-safe.
1546
Brett Cannonbf3157b2008-08-14 05:00:03 +00001547- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1548 since mimetools itself is deprecated. Because modules are cached, all
1549 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1550
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001551- Issue #3134: shutil referenced undefined WindowsError symbol.
1552
Robert Schuppenies14646332008-08-10 11:01:53 +00001553- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1554 menu entries were not deleted.
1555
Brett Cannon83e81842008-08-09 23:30:55 +00001556- Copied the implementation of reduce() to _functools.reduce() to have a
1557 version that did not raise a DeprecationWarning under -3.
1558
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001559- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1560 a MemoryError rather than silently stop the iteration.
1561
Guido van Rossum59ce9012008-08-09 14:55:34 +00001562- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1563 to _sre.compile() will now be rejected. This should not affect anybody
1564 since the re.compile() function never generates invalid re-bytecode.
1565
Skip Montanaroa032bf42008-08-08 22:52:51 +00001566- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1567 upon first access it can be automatically initialized from the csv file if
1568 it wasn't initialized during instantiation.
1569
Brett Cannon3aa2a492008-08-06 22:28:09 +00001570- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1571 the reload() built-in has been removed.
1572
Brett Cannon7e30b672008-08-04 21:52:25 +00001573- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001574 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001585 asking for a specific length. This problem only affected files opened

1638
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001639*Release date: 17-Jul-2008*

1642-----------------
1643
Georg Brandl3e483f62008-07-16 22:57:41 +00001644- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1645 its methods now allow for items objects that can be converted to
1646 an integer using operator.index().
1647
Mark Dickinson64b7e502008-07-16 09:40:03 +00001648- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1649 produced a ValueError instead of giving the correct float.
1650
Eric Smitha5fa5a22008-07-16 00:11:49 +00001651- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1652 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1653
Mark Dickinson7103aa42008-07-15 19:08:33 +00001654- Issue #3008: the float type has a new instance method 'float.hex'
1655 and a new class method 'float.fromhex' to convert floating-point
1656 numbers to and from hexadecimal strings, respectively.
1657
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001658- Issue #2235: __hash__ is once again inherited by default. To allow
1659 collections.Hashable to remain meaningful in the presence of the
1660 default hash implementation (object.__hash__), it is now possible
1661 to explicit block inheritance of hash by setting __hash__=None at
1662 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1663 level.
1664
Nick Coghlanb028f502008-07-13 14:52:36 +00001665- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1666 the parent module cannot be found while performing an absolute import.
1667 This means that an incorrectly defined __package__ attribute will
1668 now only prevent relative imports in that module rather than causing
1669 all imports from that module to fail.
1670
Nick Coghlan14ff9942008-07-08 14:21:42 +00001671- Issue #2517: Allow unicode messages in Exceptions again by correctly

1680 threading.local: the first member set by a thread could be saved in
1681 another thread's dictionary.
1682
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001683- Issue #3004: Minor change to slice.indices(): the start and stop
1684 arguments are now treated identically, making the behaviour easier
1685 to describe and understand. For example, slice(None, -10,
1686 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1687 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1688 10, -1).
1689
Georg Brandl278fc502008-07-19 12:46:12 +00001690- Issue #3219: Calling a function with repeated keyword arguments,
1691 f(a=2, a=23), would not cause a syntax error. This was a regression
1692 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001693
Georg Brandl278fc502008-07-19 12:46:12 +00001694- Issue #2862: Make int and float freelist management consistent with
1695 other freelists. Changes their CompactFreeList apis into
1696 ClearFreeList apis and calls them via gc.collect().

1702 api functions without holding the GIL, which could lead to a fatal
1703 error when they failed.
1704
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001705- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001730- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1731 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001732 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001733 content-length. The problem had been corrected in the 2.4 branch, but never
1734 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001749- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1750 handling is now the same as that of other special attributes like __name__).

2162- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002163
2164- The PyString functions have been renamed to PyBytes. A batch of
2165 defines were added so that the linker still sees the original
2166 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002204- Issue #1631171: Re-implement the 'warnings' module in C (the
2205 original Python code has been kept as backup). This will allow for
2206 using the 'warning's machinery in such places as the parser where
2207 use of pure Python code is not possible. Both the ``showarning()``
2208 and ``formatwarning()`` gain an optional 'line' argument which is
2209 not called by default for backwards-compatibility reasons. Setting
2210 ``warnings.showwarning()`` to an implementation that lacks support
2211 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002253- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002254 extension modules between 32 and 64 bit platforms. See the distutls

2267 so the controlled environment will more closely mirror the typical
2268 script environment. This supports setup.py scripts that refer to
2269 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002274- Issue #2550: The approach used by client/server code for obtaining
2275 ports to listen on in network-oriented tests has been refined in an
2276 effort to facilitate running multiple instances of the entire
2277 regression test suite in parallel without issue.
2278 test_support.bind_port() has been fixed such that it will always
2279 return a unique port -- which wasn't always the case with the
2280 previous implementation, especially if socket options had been set
2281 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2282 new implementation of bind_port() will actually raise an exception
2283 if it is passed an AF_INET/SOCK_STREAM socket with either the
2284 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2285 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2286 the socket it's been passed. This currently only applies to
2287 Windows. This option prevents any other sockets from binding to the
2288 host/port we've bound to, thus removing the possibility of the
2289 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2290 when a second SOCK_STREAM socket binds and accepts to a host/port
2291 that's already been bound by another socket. The optional preferred
2292 port parameter to bind_port() has been removed. Under no
2293 circumstances should tests be hard coding ports!
2294
2295 test_support.find_unused_port() has also been introduced, which will
2296 pass a temporary socket object to bind_port() in order to obtain an
2297 unused port. The temporary socket object is then closed and
2298 deleted, and the port is returned. This method should only be used
2299 for obtaining an unused port in order to pass to an external program
2300 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2301 a parameter to a server-oriented class that doesn't give you direct
2302 access to the underlying socket used.
2303
2304 Finally, test_support.HOST has been introduced, which should be used
2305 for the host argument of any relevant socket calls (i.e. bind and
2306 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002307
2308 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002309 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002310 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2311 test_asynchat and test_socket_ssl.
2312
Georg Brandl3ee81df2008-05-17 18:14:43 +00002313 It is now possible for multiple instances of the regression test
2314 suite to run in parallel without issue.

2582
Fred Drakea8ee94b2008-03-01 02:45:07 +00002583- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002584 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002589
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002590- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002591 issue 215555 for a discussion.
2592
Eric Smitha73fbe72008-02-23 03:09:44 +00002593- Added the future_builtins module, which contains hex() and oct().
2594 These are the PEP 3127 version of these functions, designed to be
2595 compatible with the hex() and oct() builtins from Python 3.0. They
2596 differ slightly in their output formats from the existing, unchanged
2597 Python 2.6 builtins. The expected usage of the future_builtins
2598 module is:
2599 from future_builtins import hex, oct
2600
Eric Smith7ef40bf2008-02-20 23:34:22 +00002601- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2602 exponents for exponents with absolute value < 100. Follows C99
2603 standard. This is a change on Windows, which would use 3 digits.
2604 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2605 so that any alterations it does to the resulting string will be
2606 available in stringlib/formatter.h (for float.__format__).
2607
Eric Smith5a3c1352008-02-19 13:21:56 +00002608- Implemented PEP 3101, Advanced String Formatting. This adds a new
2609 builtin format(); a format() method for str and unicode; a
2610 __format__() method to object, str, unicode, int, long, float, and
2611 datetime; the class string.Formatter; and the C API
2612 PyObject_Format().
2613
Georg Brandl3ee81df2008-05-17 18:14:43 +00002614- Fixed several potential crashes, all caused by specially crafted
2615 __del__ methods exploiting objects in temporarily inconsistent
2616 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002617
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002618- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002619 prevent a possible crash: an Abstract Base Class would try to access
2620 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002625- Clear all free lists during a gc.collect() of the highest generation
2626 in order to allow pymalloc to free more arenas. Python may give back
2627 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002628
Georg Brandl3ee81df2008-05-17 18:14:43 +00002629- Issue #2045: Fix an infinite recursion triggered when printing a
2630 subclass of collections.defaultdict, if its default_factory is set
2631 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002632
Christian Heimesf75dbef2008-02-08 00:11:31 +00002633- Fixed a minor memory leak in dictobject.c. The content of the free
2634 list was not freed on interpreter shutdown.
2635
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636- Limit free list of method and builtin function objects to 256
2637 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002639- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2640 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002641 to compact the internal free lists of pre-allocted ints and floats.
2642
Georg Brandl3ee81df2008-05-17 18:14:43 +00002643- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2644 calls. Python expected the return type int but the fork familie
2645 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002659- Patch #1473257: generator objects gain a gi_code attribute. This is
2660 the same object as the func_code attribute of the function that
2661 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002662
Georg Brandl3ee81df2008-05-17 18:14:43 +00002663- Issue #1920: "while 0" statements were completely removed by the
2664 compiler, even in the presence of an "else" clause, which is
2665 supposed to be run when the condition is false. Now the compiler
2666 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002667
Guido van Rossumeead05f2008-01-24 18:21:02 +00002668- A few crashers fixed: weakref_in_del.py (issue #1377858);

Christian Heimes082c9b02008-01-23 14:20:50 +00002677 several extension methods and modules do not work without unicode
2678 support.
2679
Georg Brandl26543b12008-01-21 18:36:51 +00002680- Issue #1882: when compiling code from a string, encoding cookies in the
2681 second line of code were not always recognized correctly.
2682
Georg Brandl14404b62008-01-19 19:27:05 +00002683- Issue #1679: "0x" was taken as a valid integer literal.
2684
Georg Brandl6caad7d2008-01-26 14:19:22 +00002685- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002686 added.
2687
Christian Heimesc94e2b52008-01-14 04:13:37 +00002688- sys.float_info / PyFloat_GetInfo: The floating point information
2689 object was converted from a dict to a specialized structseq object.
2690
Georg Brandl3ee81df2008-05-17 18:14:43 +00002691- Patch #1816: Added sys.flags structseq. It exposes the status of
2692 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Objects/structseq.c: Implemented new structseq representation. The
2695 patch makes structseqs (e.g. the return value of os.stat) more
2696 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002697
Georg Brandl3ee81df2008-05-17 18:14:43 +00002698- Patch #1700288: added a type attribute cache that caches method
2699 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002700
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002701- Bug #1776: __import__() no longer accepts filenames on any platform.
2702 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002703
Georg Brandlaed6c662008-01-07 17:25:53 +00002704- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2705
Georg Brandl3ee81df2008-05-17 18:14:43 +00002706- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2707 envvar and sys.dont_write_bytecode attribute. All these can be set
2708 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002709
Georg Brandl3ee81df2008-05-17 18:14:43 +00002710- Improve some exception messages when Windows fails to load an
2711 extension module. Now we get for example '%1 is not a valid Win32
2712 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002713
Georg Brandl3ee81df2008-05-17 18:14:43 +00002714- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002716- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2717 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002718
Christian Heimes0a8143f2007-12-18 23:22:54 +00002719- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002720 and INF. float("nan"), float("inf") and float("-inf") now work on
2721 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002722
Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Compiler now generates simpler and faster code for dictionary
2724 literals. The oparg for BUILD_MAP now indicates an estimated
2725 dictionary size. There is a new opcode, STORE_MAP, for adding
2726 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002736- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002737 SystemError.
2738
Nick Coghlanef01d822007-12-03 12:55:17 +00002739- PEP 366: Allow explicit relative imports when executing modules

2744 running, and if the deallocation of its frames somehow calls the
2745 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002746

2751
Georg Brandl3ee81df2008-05-17 18:14:43 +00002752- Issue #1460: The utf-7 incremental decoder did not accept truncated
2753 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002754
Georg Brandl3ee81df2008-05-17 18:14:43 +00002755- Patch #1739468: Directories and zipfiles containing a __main__.py
2756 file can now be directly executed by passing their name to the
2757 interpreter. The directory/zipfile is automatically inserted as the
2758 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002759
Georg Brandl3ee81df2008-05-17 18:14:43 +00002760- Issue #1265: Fix a problem with sys.settrace, if the tracing
2761 function uses a generator expression when at the same time the
2762 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002763
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002764- sets and frozensets now have an isdisjoint() method.
2765
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002766- optimize the performance of builtin.sum().
2767
Neal Norwitz44f326e2007-10-05 05:29:17 +00002768- Fix warnings found by the new version of the Coverity checker.
2769
Georg Brandl3ee81df2008-05-17 18:14:43 +00002770- The enumerate() builtin function is no longer bounded to sequences
2771 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2772 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002773
Georg Brandl3ee81df2008-05-17 18:14:43 +00002774- Issue #1686386: Tuple's tp_repr did not take into account the
2775 possibility of having a self-referential tuple, which is possible
2776 from C code. Nor did object's tp_str consider that a type's tp_str
2777 could do something that could lead to an inifinite recursion.
2778 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2779 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002780
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781- Issue #1164: It was possible to trigger deadlock when using the
2782 'print' statement to write to a file since the GIL was not released
2783 as needed. Now PyObject_Print() does the right thing along with
2784 various tp_print implementations of the built-in types and those in
2785 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- Issue #1147: Exceptions were directly allowing string exceptions in
2788 their throw() method even though string exceptions no longer
2789 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Issue #1096: Prevent a segfault from getting the repr of a very
2792 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002793
Brett Cannon1e534b52007-09-07 04:18:30 +00002794- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002795 PyObject_Call() never calling back out to Python code to trigger
2796 recursion depth updates/checks. Required the creation of a static
2797 RuntimeError instance in case normalizing an exception put the
2798 recursion check value past its limit. Fixes crashers
2799 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002800
Georg Brandl3ee81df2008-05-17 18:14:43 +00002801- Patch #1031213: Decode source line in SyntaxErrors back to its

2805 with %G.
2806
Georg Brandl3ee81df2008-05-17 18:14:43 +00002807- Prevent expandtabs() on string and unicode objects from causing a
2808 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002809

Georg Brandla5ea6892007-06-01 11:33:33 +00002813
Neal Norwitz0ac60192007-05-27 04:08:54 +00002814- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002815 __*__ attributes. (Some already existed, e.g., __doc__ and
2816 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002817
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002818- Add -3 option to the interpreter to warn about features that are
2819 deprecated and will be changed/removed in Python 3.0.
2820
Georg Brandl2134e752007-05-21 20:34:16 +00002821- Patch #1686487: you can now pass any mapping after '**' in function
2822 calls.
2823
Collin Winter62903052007-05-18 23:11:24 +00002824- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002825 "except E as target:". This is to provide forwards compatibility
2826 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002827
Brett Cannon229cee22007-05-05 01:34:02 +00002828- Deprecate BaseException.message as per PEP 352.
2829
Georg Brandl3ee81df2008-05-17 18:14:43 +00002830- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002831 inherited from a builtin base.
2832
Vinay Sajip8549ce32007-05-06 17:53:37 +00002833- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002834 setting a plain string, ie don't expand to single letter identifiers.
2835
Raymond Hettinger13936692007-04-11 18:40:58 +00002836- Request #1191699: Slices can now be pickled.
2837
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002838- Request #1193128: str.translate() now allows a None argument for
2839 translations that only remove characters without re-mapping the
2840 remaining characters.
2841
Georg Brandl5cb76c12007-03-21 09:00:39 +00002842- Patch #1682205: a TypeError while unpacking an iterable is no longer
2843 masked by a generic one with the message "unpack non-sequence".
2844
Neal Norwitzaa754b72007-03-21 06:39:48 +00002845- Remove unused file Python/fmod.c.
2846
Guido van Rossum143b5642007-03-23 04:58:42 +00002847- Bug #1683368: The object.__init__() and object.__new__() methods are
2848 now stricter in rejecting excess arguments. The only time when
2849 either allows excess arguments is when it is not overridden and the
2850 other one is. For backwards compatibility, when both are
2851 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002852 warning later). Also, type.__init__() insists on the same signature
2853 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002854
Georg Brandl3ee81df2008-05-17 18:14:43 +00002855- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2856 object to complex using its __complex__() method before falling back
2857 to the __float__() method. Therefore, the functions in the cmath
2858 module now can operate on objects that define a __complex__()
2859 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002860
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Patch #1623563: allow __class__ assignment for classes with
2862 __slots__. The old and the new class are still required to have the
2863 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002864
Georg Brandl3ee81df2008-05-17 18:14:43 +00002865- Patch #1642547: Fix an error/crash when encountering syntax errors
2866 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002868- Patch #1462488: Python no longer segfaults when
2869 ``object.__reduce_ex__()`` is called with an object that is faking
2870 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Patch #1680015: Don't modify __slots__ tuple if it contains an
2873 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002875- Patch #1444529: the builtin compile() now accepts keyword arguments.
2876
Georg Brandl7b9c5552007-03-12 14:30:05 +00002877- Bug #1678647: write a newline after printing an exception in any
2878 case, even when converting the value to a string failed.
2879
Georg Brandl871f1bc2007-03-12 13:17:36 +00002880- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002881 its argument, if it exists. If not, it will work like before. This
2882 allows customizing the output of dir() in the presence of a
2883 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002884
Collin Winter276887b2007-03-12 16:11:39 +00002885- Patch #922167: Python no longer segfaults when faced with infinitely
2886 self-recursive reload() calls (as reported by bug #742342).
2887
Georg Brandl3ee81df2008-05-17 18:14:43 +00002888- Patch #1675981: remove unreachable code from ``type.__new__()``
2889 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00002890
Georg Brandl3ee81df2008-05-17 18:14:43 +00002891- Patch #1491866: change the complex() constructor to allow
2892 parthensized forms. This means complex(repr(x)) now works instead of
2893 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002894
Georg Brandlaa2321b2007-03-07 00:40:28 +00002895- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002896 makes the filenames the warning module prints much more sensible
2897 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002898
Georg Brandl49aafc92007-03-07 00:34:46 +00002899- Variant of patch #697613: don't exit the interpreter on a SystemExit
2900 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002901 variable is given, but break into the interactive interpreter just
2902 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002907- Bug #1674503: close the file opened by execfile() in an error
2908 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00002909
Georg Brandl0fca97a2007-03-05 22:28:08 +00002910- Patch #1674228: when assigning a slice (old-style), check for the
2911 sq_ass_slice instead of the sq_slice slot.
2912
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913- When printing an unraisable error, don't print exceptions. before
2914 the name. This duplicates the behavior whening normally printing
2915 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00002916

Facundo Batistad918a652007-04-24 13:54:38 +00003406- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003407 the client's request was successfully received, understood, and
3408 accepted. Now in these cases no error is raised in urllib (issue
3409 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003417- Added a timeout parameter to the constructor of other protocols
3418 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3419 work started with create_connection() and timeout in httplib, and
3420 closes patch #723312.
3421
Vinay Sajip8549ce32007-05-06 17:53:37 +00003422- Patch #1676823: Added create_connection() to socket.py, which may be
3423 called with a timeout, and use it from httplib (whose HTTPConnection

Georg Brandl3ee81df2008-05-17 18:14:43 +00003448 AttributeError instead of an IOError when the server's response
3449 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003450

Georg Brandl3ee81df2008-05-17 18:14:43 +00003455- Patch #1429539: pdb now correctly initializes the __main__ module
3456 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003457 correctly now.
3458

Georg Brandl3ee81df2008-05-17 18:14:43 +00003466- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00003479- Patch #1581073: add a flag to textwrap that prevents the dropping of
3480 whitespace while wrapping.
3481
Georg Brandl92a6bae2007-03-13 17:43:32 +00003482- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483 are set for invalid interpolation sequences that would lead to
3484 errors on reading back those values.

3527 returned string up to the first NUL character.

3538
Georg Brandl3ee81df2008-05-17 18:14:43 +00003539- unittest now verifies more of its assumptions. In particular,
3540 TestCase and TestSuite subclasses (not instances) are no longer
3541 accepted in TestSuite.addTest(). This should cause no
3542 incompatibility since it never made sense with ordinary subclasses
3543 -- the failure just occurred later, with a more cumbersome
3544 exception.

3553 given a unicode argument and os.listdir() returns unicode filenames.
3554
Georg Brandl3ee81df2008-05-17 18:14:43 +00003555- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00003933 time so that opening a database previously created with the DB_DUP
3934 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3935 opens. Specifically: dictionary assignment to a DB object will
3936 replace all values for a given key when the database allows
3937 duplicate values. DB users should use DB.put(k, v) when they want
3938 to store duplicates; not DB[k] = v.

3945 characters with ASCII value less than 32. Also, it correctly quotes
3946 dots only if they occur on a single line, as opposed to the previous
3947 behavior of quoting dots if they are the second character of any
3948 line.

4294 of w# format code incorrectly truncated the length to an int, even
4295 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4296 incorrect results with huge strings.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004326- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4327 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
