91
Tarek Ziadé06426fc2010-01-11 22:54:57 +000092- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

102
Antoine Pitrou0b074572010-01-08 19:21:34 +0000103- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles

105 no alternative to cPickle if you care about performance. Patch by Florent
106 Xicluna.
107

143
Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000144- Issue #7318: multiprocessing now uses a timeout when it fails to establish

163
Gregory P. Smith6da85f92009-11-01 18:31:13 +0000164- Issue #7246 & Issue #7208: getpass now properly flushes input before
165 reading from stdin so that existing input does not confuse it and
166 lead to incorrect entry or an IOError. It also properly flushes it
167 afterwards to avoid the terminal echoing the input afterwards on

177
R. David Murray7034db32009-10-27 23:39:06 +0000178- Issue #7082: When falling back to the MIME 'name' parameter, the
179 correct place to look for it is the Content-Type header.
180
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000181- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
182 larger than emax.
183
Antoine Pitrouf3a0ff62009-10-27 17:46:09 +0000184- Issue #7205: Fix a possible deadlock when using a BZ2File object from

939- Issue #4197: doctests in modules loaded via zipimport (or any other PEP
940 302 conformant loader) will now work correctly in most cases (they
941 are still subject to the constraints that exist for all code running
942 from inside a module loaded via a PEP 302 loader and attempting to

1101What's New in Python 2.6.1
1102==========================
1103
1104*Release date: 04-Dec-2008*
1105
1106Core and Builtins
1107-----------------
1108
1109- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1110 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1111 instead of throwing a MemoryError.
1112
1113- Issue #4367: Python would segfault during compiling when the unicodedata
1114 module couldn't be imported and \N escapes were present.
1115
1116- Issue #4348: Some bytearray methods returned that didn't cause any change to
1117 the bytearray, returned the same bytearray instead of a copy.
1118
1119- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1120
1121- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1122
1123- Issue #4048: The parser module now correctly validates relative imports.
1124
1125- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an

1130
1131- Issue #4209: Enabling unicode_literals and the print_function in the same
1132 __future__ import didn't work.
1133
1134- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1135 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1136 really executed because I cannot move to such directory on win2k)
1137
1138- Issue #4069: When set.remove(element) is used with a set element, the element
1139 is temporarily replaced with an equivalent frozenset. But the eventual
1140 KeyError would always report the empty frozenset([]) as the missing key. Now
1141 it correctly refers to the initial element.
1142
1143- Fixed C99 style comments in several files. Python is now C89 compatible
1144 again.

1295 PY_FORMAT_SIZE_T is designed to select the correct format for the OS

1310 a unicode argument.
1311
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001312- Issue #3683: Fix compilation when --without-threads is given.

Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001314- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001315 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001316 was correctly parsed but parsing of subsequent arguments failed.
1317
Vinay Sajip35e3b032008-09-01 14:33:59 +00001318- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001319 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1320 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1321 when given a tuple of classes as second argument, were looking up
1322 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1323 type object.
1324
Neal Norwitz18aa3882008-08-24 05:04:52 +00001325- Fix crashes on memory allocation failure found with failmalloc.

1394 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1395 for catch_warnings() also led to an improvement in the raising of a
1396 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001418- Issue #2975: When compiling several extension modules with Visual Studio 2008
1419 from the same python interpreter, some environment variables would grow
1420 without limit.
1421
Benjamin Peterson37346b22008-08-23 20:27:43 +00001422- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001459What's New in Python 2.6 beta 3?
1460================================
1461
Barry Warsaw07a4a382008-08-21 01:15:08 +00001462*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001463
1464Core and Builtins
1465-----------------
1466
Guido van Rossumf8402962008-08-20 15:01:50 +00001467- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1468 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1469 extensions do not automatically benefit from the class attribute
1470 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1471 to their tp_flags field if they care. This is a backwards
1472 compatibility feature; in 3.0, all types will use the cache by
1473 default.
1474
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001475- Keyword arguments can now follow starred arguments. (``f(a, *args,
1476 keyword=23)`` is now valid syntax.)
1477
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001478- ctypes function pointers that are COM methods have a boolean True
1479 value again.
1480
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001481- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1482 by denying s# to parse objects that have a releasebuffer procedure,
1483 and introducing s*.
1484
Georg Brandl1e13ea92008-08-11 09:07:59 +00001485- Issue #3537: Fix an assertion failure when an empty but presized dict
1486 object was stored in the freelist.
1487
Mark Dickinsonb6467572008-08-04 21:30:09 +00001488- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1489 ValueError consistently across platforms.
1490
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001491- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1492 (64bit Unix, for example), unichr() would truncate its argument and return
1493 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1494
Neal Norwitze7d8be82008-07-31 17:17:14 +00001495- Apply security patches from Apple.
1496
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001497- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1498 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1499
Antoine Pitrou92f82162008-07-25 22:22:08 +00001500- Issue #1819: function calls with several named parameters are now on
1501 average 35% faster (as measured by pybench).
1502
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001503- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1504 the python debugger steps into a class statement: the free variables (local
1505 variables defined in an outer scope) would be deleted from the outer scope.
1506
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001507- Issue #2620: Overflow checking when allocating or reallocating memory
1508 was not always being done properly in some python types and extension
1509 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1510 all been updated to perform better checks and places in the code that
1511 would previously leak memory on the error path when such an allocation
1512 failed have been fixed.

1515-------
1516
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001517- Issue #3612: Added some missing basic types in ctypes.wintypes.
1518
Benjamin Petersone977ad42008-08-20 01:42:01 +00001519- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1520 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1521
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001522- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1523 version reported by these tools does not necessarily follow the python
1524 version numbering scheme, so the module is less strict when parsing it.
1525
Nick Coghlanf70385a2008-08-18 12:42:46 +00001526- Issue #2235: Added Py3k warnings for types which will become unhashable
1527 under the stricter __hash__ inheritance rules in 3.0. Several types
1528 which did not meet the rules for hash invariants and were already
1529 unhashable in 3.0 have now been explicitly flagged as unhashable in
1530 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1531 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1532
Brett Cannon88f801d2008-08-18 00:46:22 +00001533- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1534 imported into the module but exposed as part of the module's API.
1535
Brett Cannon7b96f072008-08-18 00:41:11 +00001536- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1537
Brett Cannon46225e72008-08-18 00:36:52 +00001538- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1539
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001540- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1541
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001542- Issue #3575: Incremental decoder's decode function now takes bytearray
1543 by using 's*' instead of 't#'.
1544
Jesus Cea585ad8a2009-07-02 15:37:21 +00001545- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001546 fails unicode conversion on 2nd parameter. (windows only)
1547
Facundo Batista94f243a2008-08-17 03:38:39 +00001548- Issue 2464. urllib2 now supports a malformation in the URL received
1549 in a redirect.
1550
Brett Cannonabe423e2008-08-16 21:47:07 +00001551- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001552 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001553
Facundo Batistaeb90b782008-08-16 14:44:07 +00001554- Issue #2776: fixed small issue when handling an URL with double slash
1555 after a 302 response in the case of not going through a proxy.
1556
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001557- Issue #2676: in the email package, content-type parsing was hanging on
1558 pathological input because of quadratic or exponential behaviour of a
1559 regular expression.
1560
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001561- Issue #3476: binary buffered reading through the new "io" library is now
1562 thread-safe.
1563
Brett Cannonbf3157b2008-08-14 05:00:03 +00001564- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1565 since mimetools itself is deprecated. Because modules are cached, all
1566 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1567
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001568- Issue #3134: shutil referenced undefined WindowsError symbol.
1569
Robert Schuppenies14646332008-08-10 11:01:53 +00001570- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1571 menu entries were not deleted.
1572
Brett Cannon83e81842008-08-09 23:30:55 +00001573- Copied the implementation of reduce() to _functools.reduce() to have a
1574 version that did not raise a DeprecationWarning under -3.
1575
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001576- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1577 a MemoryError rather than silently stop the iteration.
1578
Guido van Rossum59ce9012008-08-09 14:55:34 +00001579- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1580 to _sre.compile() will now be rejected. This should not affect anybody
1581 since the re.compile() function never generates invalid re-bytecode.
1582
Skip Montanaroa032bf42008-08-08 22:52:51 +00001583- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1584 upon first access it can be automatically initialized from the csv file if
1585 it wasn't initialized during instantiation.
1586
Brett Cannon3aa2a492008-08-06 22:28:09 +00001587- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1588 the reload() built-in has been removed.
1589
Brett Cannon7e30b672008-08-04 21:52:25 +00001590- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001591 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001602 asking for a specific length. This problem only affected files opened

1646
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001647- Issue #643841: The language reference now provides more detailed

1655
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001656*Release date: 17-Jul-2008*

1659-----------------
1660
Georg Brandl3e483f62008-07-16 22:57:41 +00001661- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1662 its methods now allow for items objects that can be converted to
1663 an integer using operator.index().
1664
Mark Dickinson64b7e502008-07-16 09:40:03 +00001665- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1666 produced a ValueError instead of giving the correct float.
1667
Eric Smitha5fa5a22008-07-16 00:11:49 +00001668- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1669 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1670
Mark Dickinson7103aa42008-07-15 19:08:33 +00001671- Issue #3008: the float type has a new instance method 'float.hex'
1672 and a new class method 'float.fromhex' to convert floating-point
1673 numbers to and from hexadecimal strings, respectively.
1674
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001675- Issue #2235: __hash__ is once again inherited by default. To allow
1676 collections.Hashable to remain meaningful in the presence of the
1677 default hash implementation (object.__hash__), it is now possible
1678 to explicit block inheritance of hash by setting __hash__=None at
1679 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1680 level.
1681
Nick Coghlanb028f502008-07-13 14:52:36 +00001682- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1683 the parent module cannot be found while performing an absolute import.
1684 This means that an incorrectly defined __package__ attribute will
1685 now only prevent relative imports in that module rather than causing
1686 all imports from that module to fail.
1687
Nick Coghlan14ff9942008-07-08 14:21:42 +00001688- Issue #2517: Allow unicode messages in Exceptions again by correctly

1698 another thread's dictionary.
1699
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001700- Issue #3004: Minor change to slice.indices(): the start and stop
1701 arguments are now treated identically, making the behaviour easier
1702 to describe and understand. For example, slice(None, -10,
1703 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1704 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1705 10, -1).
1706
Georg Brandl278fc502008-07-19 12:46:12 +00001707- Issue #3219: Calling a function with repeated keyword arguments,
1708 f(a=2, a=23), would not cause a syntax error. This was a regression
1709 from 2.4 caused by the switch to the new compiler.

1712 other freelists. Changes their CompactFreeList apis into

1719 api functions without holding the GIL, which could lead to a fatal
1720 error when they failed.
1721
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001722- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001747- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1748 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001749 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001750 content-length. The problem had been corrected in the 2.4 branch, but never
1751 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001766- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
1767 handling is now the same as that of other special attributes like __name__).
1768

2176
Georg Brandl74a1dea2008-05-28 11:21:39 +00002177- Add ``PyType_Modified()`` as a public API to clear the type cache.
2178
2179- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00002180
2181- The PyString functions have been renamed to PyBytes. A batch of
2182 defines were added so that the linker still sees the original
2183 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002221- Issue #1631171: Re-implement the 'warnings' module in C (the
2222 original Python code has been kept as backup). This will allow for
2223 using the 'warning's machinery in such places as the parser where
2224 use of pure Python code is not possible. Both the ``showarning()``
2225 and ``formatwarning()`` gain an optional 'line' argument which is
2226 not called by default for backwards-compatibility reasons. Setting
2227 ``warnings.showwarning()`` to an implementation that lacks support
2228 for the ``line`` argument will raise a DeprecationWarning.

2252
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002253- The getpass module has been improved on Unix. It now uses /dev/tty
2254 by default and uses stderr instead of stdout. A GetPassWarning is
2255 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002270- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002271 extension modules between 32 and 64 bit platforms. See the distutls
2272 build documentation for more information.

2275 threads at once without fear of crashing the Python interpreter. If
2276 file.close() is called while an object is in use by another thread
2277 an IOError exception will be raised and the file will not be closed.
2278
Thomas Hellerf7906482008-04-04 19:43:25 +00002279- The bundled libffi copy is now in sync with the recently released

2284 so the controlled environment will more closely mirror the typical
2285 script environment. This supports setup.py scripts that refer to
2286 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002291- Issue #2550: The approach used by client/server code for obtaining
2292 ports to listen on in network-oriented tests has been refined in an
2293 effort to facilitate running multiple instances of the entire
2294 regression test suite in parallel without issue.
2295 test_support.bind_port() has been fixed such that it will always
2296 return a unique port -- which wasn't always the case with the
2297 previous implementation, especially if socket options had been set
2298 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2299 new implementation of bind_port() will actually raise an exception
2300 if it is passed an AF_INET/SOCK_STREAM socket with either the
2301 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2302 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2303 the socket it's been passed. This currently only applies to
2304 Windows. This option prevents any other sockets from binding to the
2305 host/port we've bound to, thus removing the possibility of the
2306 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2307 when a second SOCK_STREAM socket binds and accepts to a host/port
2308 that's already been bound by another socket. The optional preferred
2309 port parameter to bind_port() has been removed. Under no
2310 circumstances should tests be hard coding ports!
2311
2312 test_support.find_unused_port() has also been introduced, which will
2313 pass a temporary socket object to bind_port() in order to obtain an
2314 unused port. The temporary socket object is then closed and
2315 deleted, and the port is returned. This method should only be used
2316 for obtaining an unused port in order to pass to an external program
2317 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2318 a parameter to a server-oriented class that doesn't give you direct
2319 access to the underlying socket used.
2320
2321 Finally, test_support.HOST has been introduced, which should be used
2322 for the host argument of any relevant socket calls (i.e. bind and
2323 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002324
2325 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002326 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002327 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2328 test_asynchat and test_socket_ssl.
2329
Georg Brandl3ee81df2008-05-17 18:14:43 +00002330 It is now possible for multiple instances of the regression test
2331 suite to run in parallel without issue.

2598-----------------
2599
Fred Drakea8ee94b2008-03-01 02:45:07 +00002600- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002601 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00002606
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002607- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002608 issue 215555 for a discussion.
2609
Eric Smitha73fbe72008-02-23 03:09:44 +00002610- Added the future_builtins module, which contains hex() and oct().
2611 These are the PEP 3127 version of these functions, designed to be
2612 compatible with the hex() and oct() builtins from Python 3.0. They
2613 differ slightly in their output formats from the existing, unchanged
2614 Python 2.6 builtins. The expected usage of the future_builtins
2615 module is:
2616 from future_builtins import hex, oct
2617
Eric Smith7ef40bf2008-02-20 23:34:22 +00002618- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2619 exponents for exponents with absolute value < 100. Follows C99
2620 standard. This is a change on Windows, which would use 3 digits.
2621 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2622 so that any alterations it does to the resulting string will be
2623 available in stringlib/formatter.h (for float.__format__).
2624
Eric Smith5a3c1352008-02-19 13:21:56 +00002625- Implemented PEP 3101, Advanced String Formatting. This adds a new
2626 builtin format(); a format() method for str and unicode; a
2627 __format__() method to object, str, unicode, int, long, float, and
2628 datetime; the class string.Formatter; and the C API
2629 PyObject_Format().
2630
Georg Brandl3ee81df2008-05-17 18:14:43 +00002631- Fixed several potential crashes, all caused by specially crafted
2632 __del__ methods exploiting objects in temporarily inconsistent
2633 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002634
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002635- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002636 prevent a possible crash: an Abstract Base Class would try to access
2637 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002642- Clear all free lists during a gc.collect() of the highest generation
2643 in order to allow pymalloc to free more arenas. Python may give back
2644 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002645
Georg Brandl3ee81df2008-05-17 18:14:43 +00002646- Issue #2045: Fix an infinite recursion triggered when printing a
2647 subclass of collections.defaultdict, if its default_factory is set
2648 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002649
Christian Heimesf75dbef2008-02-08 00:11:31 +00002650- Fixed a minor memory leak in dictobject.c. The content of the free
2651 list was not freed on interpreter shutdown.
2652
Georg Brandl3ee81df2008-05-17 18:14:43 +00002653- Limit free list of method and builtin function objects to 256
2654 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002656- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2657 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002658 to compact the internal free lists of pre-allocted ints and floats.
2659
Georg Brandl3ee81df2008-05-17 18:14:43 +00002660- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2661 calls. Python expected the return type int but the fork familie
2662 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002663
Georg Brandl3ee81df2008-05-17 18:14:43 +00002664- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002676- Patch #1473257: generator objects gain a gi_code attribute. This is
2677 the same object as the func_code attribute of the function that
2678 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002679
Georg Brandl3ee81df2008-05-17 18:14:43 +00002680- Issue #1920: "while 0" statements were completely removed by the
2681 compiler, even in the presence of an "else" clause, which is
2682 supposed to be run when the condition is false. Now the compiler

Guido van Rossumeead05f2008-01-24 18:21:02 +00002685- A few crashers fixed: weakref_in_del.py (issue #1377858);
2686 loosing_dict_ref.py (issue #1303614, test67.py);
2687 borrowed_ref_[34].py (not in tracker).
2688
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002689- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002690 suppressed while an extension is loaded by calling SetErrorMode in
2691 dynload_win.c. The error is still reported properly.
2692
Georg Brandl3ee81df2008-05-17 18:14:43 +00002693- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002694 several extension methods and modules do not work without unicode
2695 support.
2696
Georg Brandl26543b12008-01-21 18:36:51 +00002697- Issue #1882: when compiling code from a string, encoding cookies in the
2698 second line of code were not always recognized correctly.
2699
Georg Brandl14404b62008-01-19 19:27:05 +00002700- Issue #1679: "0x" was taken as a valid integer literal.
2701
Georg Brandl6caad7d2008-01-26 14:19:22 +00002702- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002703 added.
2704
Christian Heimesc94e2b52008-01-14 04:13:37 +00002705- sys.float_info / PyFloat_GetInfo: The floating point information
2706 object was converted from a dict to a specialized structseq object.
2707
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Patch #1816: Added sys.flags structseq. It exposes the status of
2709 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002710
Georg Brandl3ee81df2008-05-17 18:14:43 +00002711- Objects/structseq.c: Implemented new structseq representation. The
2712 patch makes structseqs (e.g. the return value of os.stat) more
2713 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002714
Georg Brandl3ee81df2008-05-17 18:14:43 +00002715- Patch #1700288: added a type attribute cache that caches method
2716 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002717
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002718- Bug #1776: __import__() no longer accepts filenames on any platform.
2719 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002720
Georg Brandlaed6c662008-01-07 17:25:53 +00002721- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2722
Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2724 envvar and sys.dont_write_bytecode attribute. All these can be set
2725 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002726
Georg Brandl3ee81df2008-05-17 18:14:43 +00002727- Improve some exception messages when Windows fails to load an
2728 extension module. Now we get for example '%1 is not a valid Win32
2729 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002730
Georg Brandl3ee81df2008-05-17 18:14:43 +00002731- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002733- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2734 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002735
Christian Heimes0a8143f2007-12-18 23:22:54 +00002736- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002737 and INF. float("nan"), float("inf") and float("-inf") now work on
2738 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Compiler now generates simpler and faster code for dictionary
2741 literals. The oparg for BUILD_MAP now indicates an estimated
2742 dictionary size. There is a new opcode, STORE_MAP, for adding
2743 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002744
Georg Brandl3ee81df2008-05-17 18:14:43 +00002745- Issue #1638: %zd configure test fails on Linux.

2761 running, and if the deallocation of its frames somehow calls the
2762 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002763

Georg Brandl3ee81df2008-05-17 18:14:43 +00002769- Issue #1460: The utf-7 incremental decoder did not accept truncated
2770 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002771
Georg Brandl3ee81df2008-05-17 18:14:43 +00002772- Patch #1739468: Directories and zipfiles containing a __main__.py
2773 file can now be directly executed by passing their name to the
2774 interpreter. The directory/zipfile is automatically inserted as the
2775 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002776
Georg Brandl3ee81df2008-05-17 18:14:43 +00002777- Issue #1265: Fix a problem with sys.settrace, if the tracing
2778 function uses a generator expression when at the same time the
2779 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002780
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002781- sets and frozensets now have an isdisjoint() method.
2782
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002783- optimize the performance of builtin.sum().
2784
Neal Norwitz44f326e2007-10-05 05:29:17 +00002785- Fix warnings found by the new version of the Coverity checker.
2786
Georg Brandl3ee81df2008-05-17 18:14:43 +00002787- The enumerate() builtin function is no longer bounded to sequences
2788 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2789 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Issue #1686386: Tuple's tp_repr did not take into account the
2792 possibility of having a self-referential tuple, which is possible
2793 from C code. Nor did object's tp_str consider that a type's tp_str
2794 could do something that could lead to an inifinite recursion.
2795 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2796 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002797
Georg Brandl3ee81df2008-05-17 18:14:43 +00002798- Issue #1164: It was possible to trigger deadlock when using the
2799 'print' statement to write to a file since the GIL was not released
2800 as needed. Now PyObject_Print() does the right thing along with
2801 various tp_print implementations of the built-in types and those in
2802 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002803
Georg Brandl3ee81df2008-05-17 18:14:43 +00002804- Issue #1147: Exceptions were directly allowing string exceptions in
2805 their throw() method even though string exceptions no longer
2806 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002807
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808- Issue #1096: Prevent a segfault from getting the repr of a very
2809 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002810
Brett Cannon1e534b52007-09-07 04:18:30 +00002811- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812 PyObject_Call() never calling back out to Python code to trigger
2813 recursion depth updates/checks. Required the creation of a static
2814 RuntimeError instance in case normalizing an exception put the
2815 recursion check value past its limit. Fixes crashers
2816 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002817
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Patch #1031213: Decode source line in SyntaxErrors back to its

2822 with %G.
2823
Georg Brandl3ee81df2008-05-17 18:14:43 +00002824- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002831- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832 __*__ attributes. (Some already existed, e.g., __doc__ and
2833 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002834
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002835- Add -3 option to the interpreter to warn about features that are
2836 deprecated and will be changed/removed in Python 3.0.
2837
Georg Brandl2134e752007-05-21 20:34:16 +00002838- Patch #1686487: you can now pass any mapping after '**' in function
2839 calls.
2840
Collin Winter62903052007-05-18 23:11:24 +00002841- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002842 "except E as target:". This is to provide forwards compatibility
2843 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002844
Brett Cannon229cee22007-05-05 01:34:02 +00002845- Deprecate BaseException.message as per PEP 352.
2846
Georg Brandl3ee81df2008-05-17 18:14:43 +00002847- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002848 inherited from a builtin base.
2849
Vinay Sajip8549ce32007-05-06 17:53:37 +00002850- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002851 setting a plain string, ie don't expand to single letter identifiers.
2852
Raymond Hettinger13936692007-04-11 18:40:58 +00002853- Request #1191699: Slices can now be pickled.
2854
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002855- Request #1193128: str.translate() now allows a None argument for
2856 translations that only remove characters without re-mapping the
2857 remaining characters.
2858
Georg Brandl5cb76c12007-03-21 09:00:39 +00002859- Patch #1682205: a TypeError while unpacking an iterable is no longer
2860 masked by a generic one with the message "unpack non-sequence".
2861
Neal Norwitzaa754b72007-03-21 06:39:48 +00002862- Remove unused file Python/fmod.c.
2863
Guido van Rossum143b5642007-03-23 04:58:42 +00002864- Bug #1683368: The object.__init__() and object.__new__() methods are
2865 now stricter in rejecting excess arguments. The only time when
2866 either allows excess arguments is when it is not overridden and the
2867 other one is. For backwards compatibility, when both are
2868 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002869 warning later). Also, type.__init__() insists on the same signature
2870 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002871
Georg Brandl3ee81df2008-05-17 18:14:43 +00002872- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2873 object to complex using its __complex__() method before falling back
2874 to the __float__() method. Therefore, the functions in the cmath
2875 module now can operate on objects that define a __complex__()
2876 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002877
Georg Brandl3ee81df2008-05-17 18:14:43 +00002878- Patch #1623563: allow __class__ assignment for classes with
2879 __slots__. The old and the new class are still required to have the
2880 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002881
Georg Brandl3ee81df2008-05-17 18:14:43 +00002882- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00002885- Patch #1462488: Python no longer segfaults when
2886 ``object.__reduce_ex__()`` is called with an object that is faking
2887 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002888
Georg Brandl3ee81df2008-05-17 18:14:43 +00002889- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00002892- Patch #1444529: the builtin compile() now accepts keyword arguments.
2893
Georg Brandl7b9c5552007-03-12 14:30:05 +00002894- Bug #1678647: write a newline after printing an exception in any
2895 case, even when converting the value to a string failed.
2896
Georg Brandl871f1bc2007-03-12 13:17:36 +00002897- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898 its argument, if it exists. If not, it will work like before. This
2899 allows customizing the output of dir() in the presence of a
2900 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002901
Collin Winter276887b2007-03-12 16:11:39 +00002902- Patch #922167: Python no longer segfaults when faced with infinitely
2903 self-recursive reload() calls (as reported by bug #742342).
2904
Georg Brandl3ee81df2008-05-17 18:14:43 +00002905- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002908- Patch #1491866: change the complex() constructor to allow
2909 parthensized forms. This means complex(repr(x)) now works instead of
2910 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002911
Georg Brandlaa2321b2007-03-07 00:40:28 +00002912- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002913 makes the filenames the warning module prints much more sensible
2914 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002915
Georg Brandl49aafc92007-03-07 00:34:46 +00002916- Variant of patch #697613: don't exit the interpreter on a SystemExit
2917 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00002918 variable is given, but break into the interactive interpreter just
2919 like on other exceptions or normal program exit.

3418
Georg Brandlfb4b3b72007-04-24 15:27:13 +00003419- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
3420 (as opposed to the command line) will now write file names ending in
3421 ".cpp" too.
3422
Facundo Batistad918a652007-04-24 13:54:38 +00003423- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003424 the client's request was successfully received, understood, and
3425 accepted. Now in these cases no error is raised in urllib (issue
3426 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003427
Georg Brandl3ee81df2008-05-17 18:14:43 +00003428- Bug #1290505: time.strptime's internal cache of locale information

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003434- Added a timeout parameter to the constructor of other protocols
3435 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3436 work started with create_connection() and timeout in httplib, and
3437 closes patch #723312.
3438
Vinay Sajip8549ce32007-05-06 17:53:37 +00003439- Patch #1676823: Added create_connection() to socket.py, which may be
3440 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003441 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003442
Martin v. Löwis0af33882007-03-23 13:27:15 +00003443- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003450- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3451 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003452 directories.
3453

3463
Georg Brandlf66b6032007-03-14 08:27:52 +00003464- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003465 AttributeError instead of an IOError when the server's response
3466 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003467
Georg Brandl3ee81df2008-05-17 18:14:43 +00003468- Patch #957650: "%var%" environment variable references are now
3469 properly expanded in ntpath.expandvars(), also "~user" home
3470 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003471
Georg Brandl3ee81df2008-05-17 18:14:43 +00003472- Patch #1429539: pdb now correctly initializes the __main__ module
3473 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003474 correctly now.
3475
Georg Brandlbad6f192007-03-13 21:32:56 +00003476- The nonobvious commands.getstatus() function is now deprecated.

3482
Georg Brandl3ee81df2008-05-17 18:14:43 +00003483- Patch #1530482: add pydoc.render_doc() which returns the
3484 documentation for a thing instead of paging it to stdout, which
3485 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003486
Georg Brandl3ee81df2008-05-17 18:14:43 +00003487- Patch #1533909: the timeit module now accepts callables in addition

3493 parameter which can be set to False to prevent the default
3494 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00003495
Georg Brandl9e6b4702007-03-13 18:15:41 +00003496- Patch #1581073: add a flag to textwrap that prevents the dropping of
3497 whitespace while wrapping.
3498
Georg Brandl92a6bae2007-03-13 17:43:32 +00003499- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003500 are set for invalid interpolation sequences that would lead to
3501 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003502

3515
Georg Brandl94fe3f52007-03-13 09:32:11 +00003516- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003517 field names in its exception message if you try to write a record
3518 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003536

3544 returned string up to the first NUL character.

3555
Georg Brandl3ee81df2008-05-17 18:14:43 +00003556- unittest now verifies more of its assumptions. In particular,
3557 TestCase and TestSuite subclasses (not instances) are no longer
3558 accepted in TestSuite.addTest(). This should cause no
3559 incompatibility since it never made sense with ordinary subclasses
3560 -- the failure just occurred later, with a more cumbersome
3561 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003562

3570 given a unicode argument and os.listdir() returns unicode filenames.
3571
Georg Brandl3ee81df2008-05-17 18:14:43 +00003572- Patch #1673619: setup.py identifies extension modules it doesn't
3573 know how to build and those it knows how to build but that fail to
3574 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003950 time so that opening a database previously created with the DB_DUP
3951 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3952 opens. Specifically: dictionary assignment to a DB object will
3953 replace all values for a given key when the database allows
3954 duplicate values. DB users should use DB.put(k, v) when they want
3955 to store duplicates; not DB[k] = v.

3962 characters with ASCII value less than 32. Also, it correctly quotes
3963 dots only if they occur on a single line, as opposed to the previous
3964 behavior of quoting dots if they are the second character of any
3965 line.
