998What's New in Python 2.6.1
999==========================
1000
1001*Release date: 04-Dec-2008*
1002
1003Core and Builtins
1004-----------------
1005
1006- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1007 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1008 instead of throwing a MemoryError.
1009
1010- Issue #4367: Python would segfault during compiling when the unicodedata
1011 module couldn't be imported and \N escapes were present.
1012
1013- Issue #4348: Some bytearray methods returned that didn't cause any change to
1014 the bytearray, returned the same bytearray instead of a copy.
1015
1016- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1017
1018- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1019
1020- Issue #4048: The parser module now correctly validates relative imports.
1021
1022- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1023 exec statement.
1024
1025- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1026 method does not return iterators for the 4th and 5th items.
1027
1028- Issue #4209: Enabling unicode_literals and the print_function in the same
1029 __future__ import didn't work.
1030
1031- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1032 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1033 really executed because I cannot move to such directory on win2k)
1034
1035- Issue #4069: When set.remove(element) is used with a set element, the element
1036 is temporarily replaced with an equivalent frozenset. But the eventual
1037 KeyError would always report the empty frozenset([]) as the missing key. Now
1038 it correctly refers to the initial element.
1039
1040- Fixed C99 style comments in several files. Python is now C89 compatible
1041 again.

1189
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001190- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1191 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1192 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1193 ``printf`` function, whereas PyString_FromFormat has an independent
1194 implementation and uses "%zd" on all platforms for size_t values.
1195 This makes a difference on win64, where ``printf`` needs "%Id" to display
1196 64bit values.

Antoine Pitrou0668c622008-08-26 22:42:08 +00001216 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1217 mechanism. In the process, fix a bug where isinstance() and issubclass(),

1219 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1220 type object.

Benjamin Peterson37346b22008-08-23 20:27:43 +00001312Extension Modules
1313-----------------
1314
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001315- Issue #2975: When compiling several extension modules with Visual Studio 2008
1316 from the same python interpreter, some environment variables would grow
1317 without limit.
1318
Benjamin Peterson37346b22008-08-23 20:27:43 +00001319- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1320 exploitation of poor argument checking.
1321
Gerhard Häringef2276b2008-09-12 13:54:06 +00001322- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1323
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001324- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1325 remaining ones have "pysqlite_" prefix.
1326
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001327- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1333
Nick Coghland2e09382008-09-11 12:11:06 +00001334- Issue #3781: Add test.test_support.check_warnings() as a convenience
1335 wrapper for warnings.catch_warnings() that makes it easier to check
1336 that expected warning messages are being reported.
1337
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001338- Issue #3796: Some tests functions were not enabled in test_float.
1339

Martin v. Löwisab0b29b2008-09-13 08:11:57 +00001345- Issue #3833: Use a different upgrade code for Win64 installers.
1346
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001347- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001356What's New in Python 2.6 beta 3?
1357================================
1358
Barry Warsaw07a4a382008-08-21 01:15:08 +00001359*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001360
1361Core and Builtins
1362-----------------
1363
Guido van Rossumf8402962008-08-20 15:01:50 +00001364- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1365 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1366 extensions do not automatically benefit from the class attribute
1367 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1368 to their tp_flags field if they care. This is a backwards
1369 compatibility feature; in 3.0, all types will use the cache by
1370 default.
1371
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001372- Keyword arguments can now follow starred arguments. (``f(a, *args,
1373 keyword=23)`` is now valid syntax.)
1374
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001375- ctypes function pointers that are COM methods have a boolean True
1376 value again.
1377
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001378- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1379 by denying s# to parse objects that have a releasebuffer procedure,
1380 and introducing s*.
1381
Georg Brandl1e13ea92008-08-11 09:07:59 +00001382- Issue #3537: Fix an assertion failure when an empty but presized dict
1383 object was stored in the freelist.
1384
Mark Dickinsonb6467572008-08-04 21:30:09 +00001385- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1386 ValueError consistently across platforms.
1387
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001388- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1389 (64bit Unix, for example), unichr() would truncate its argument and return
1390 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1391
Neal Norwitze7d8be82008-07-31 17:17:14 +00001392- Apply security patches from Apple.
1393
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001394- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1395 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1396
Antoine Pitrou92f82162008-07-25 22:22:08 +00001397- Issue #1819: function calls with several named parameters are now on
1398 average 35% faster (as measured by pybench).
1399
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001400- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1401 the python debugger steps into a class statement: the free variables (local
1402 variables defined in an outer scope) would be deleted from the outer scope.
1403
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001404- Issue #2620: Overflow checking when allocating or reallocating memory
1405 was not always being done properly in some python types and extension
1406 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1407 all been updated to perform better checks and places in the code that
1408 would previously leak memory on the error path when such an allocation
1409 failed have been fixed.
1410
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001411Library
1412-------
1413
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001414- Issue #3612: Added some missing basic types in ctypes.wintypes.
1415
Benjamin Petersone977ad42008-08-20 01:42:01 +00001416- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1417 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1418
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001419- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1420 version reported by these tools does not necessarily follow the python
1421 version numbering scheme, so the module is less strict when parsing it.
1422
Nick Coghlanf70385a2008-08-18 12:42:46 +00001423- Issue #2235: Added Py3k warnings for types which will become unhashable
1424 under the stricter __hash__ inheritance rules in 3.0. Several types
1425 which did not meet the rules for hash invariants and were already
1426 unhashable in 3.0 have now been explicitly flagged as unhashable in
1427 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1428 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1429
Brett Cannon88f801d2008-08-18 00:46:22 +00001430- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1431 imported into the module but exposed as part of the module's API.
1432
Brett Cannon7b96f072008-08-18 00:41:11 +00001433- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1434
Brett Cannon46225e72008-08-18 00:36:52 +00001435- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1436
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001437- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1438
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001439- Issue #3575: Incremental decoder's decode function now takes bytearray
1440 by using 's*' instead of 't#'.
1441
Jesus Cea585ad8a2009-07-02 15:37:21 +00001442- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001443 fails unicode conversion on 2nd parameter. (windows only)
1444
Facundo Batista94f243a2008-08-17 03:38:39 +00001445- Issue 2464. urllib2 now supports a malformation in the URL received
1446 in a redirect.
1447
Brett Cannonabe423e2008-08-16 21:47:07 +00001448- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001449 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001450
Facundo Batistaeb90b782008-08-16 14:44:07 +00001451- Issue #2776: fixed small issue when handling an URL with double slash
1452 after a 302 response in the case of not going through a proxy.
1453
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001454- Issue #2676: in the email package, content-type parsing was hanging on
1455 pathological input because of quadratic or exponential behaviour of a
1456 regular expression.
1457
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001458- Issue #3476: binary buffered reading through the new "io" library is now
1459 thread-safe.
1460
Brett Cannonbf3157b2008-08-14 05:00:03 +00001461- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1462 since mimetools itself is deprecated. Because modules are cached, all
1463 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1464
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001465- Issue #3134: shutil referenced undefined WindowsError symbol.
1466
Robert Schuppenies14646332008-08-10 11:01:53 +00001467- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1468 menu entries were not deleted.
1469
Brett Cannon83e81842008-08-09 23:30:55 +00001470- Copied the implementation of reduce() to _functools.reduce() to have a
1471 version that did not raise a DeprecationWarning under -3.
1472
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001473- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1474 a MemoryError rather than silently stop the iteration.
1475
Guido van Rossum59ce9012008-08-09 14:55:34 +00001476- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1477 to _sre.compile() will now be rejected. This should not affect anybody
1478 since the re.compile() function never generates invalid re-bytecode.
1479
Skip Montanaroa032bf42008-08-08 22:52:51 +00001480- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1481 upon first access it can be automatically initialized from the csv file if
1482 it wasn't initialized during instantiation.
1483
Brett Cannon3aa2a492008-08-06 22:28:09 +00001484- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1485 the reload() built-in has been removed.
1486
Brett Cannon7e30b672008-08-04 21:52:25 +00001487- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001488 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00001489 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
1490 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
1491 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
1492 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
1493 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00001494
Lars Gustäbel727bd0b2008-08-02 11:26:39 +00001495- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
1496 raised an AttributeError.
1497
Benjamin Peterson01a24322008-07-28 23:35:27 +00001498- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00001499 asking for a specific length. This problem only affected files opened
1500 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001501
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00001502- Issue #3449: Update decimal module to use most recent specification
1503 (v. 1.68) and tests (v. 2.58) from IBM.
1504
Skip Montanarof9ac43f2008-07-27 00:50:41 +00001505- Issue 3437: Bug fix in robotparser parsing of Allow: lines.
1506
Raymond Hettinger8c664e82008-07-25 18:43:33 +00001507- Issue 1592: Improve error reporting when operations are attempted
1508 on a closed shelf.

1511
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001512- Issue #3120: On 64-bit Windows the subprocess module was truncating handles.
1513
1514- Issue #3303: Fix a crash in locale.strcoll() when calling it with
1515 invalid arguments.
1516
1517- Issue #3302: Fix several crashes when calling locale's gettext functions
1518 with None arguments.
1519
1520- Issue #3389: Allow resolving dotted names for handlers in logging
1521 configuration files.
1522
1523- Deprecate the sunaudio module for removal in Python 3.0.
1524
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001525- Issue #3394: zipfile.writestr sets external attributes when passed a
1526 file name rather than a ZipInfo instance, so files are extracted with
1527 mode 0600 rather than 000 under Unix.
1528
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001529- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1530 argument in python 2.5, this broke code that subclassed Popen to include its
1531 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1539-------------
1540
Nick Coghlan6e8fef02008-08-18 13:14:22 +00001541- Issue #2235: the C API function PyObject_HashNotImplemented and its
1542 interaction with the tp_hash slot (added in 2.6b2) are now documented
1543
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001544- Issue #643841: The language reference now provides more detailed
1545 coverage of the lookup process for special methods. The disclaimers
1546 regarding lack of coverage of new-style classes have also been
1547 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +00001550What's New in Python 2.6 beta 2?
1551================================
1552
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001553*Release date: 17-Jul-2008*
1554
Raymond Hettingere3ae6552008-06-20 04:18:15 +00001555Core and Builtins
1556-----------------
1557
Georg Brandl3e483f62008-07-16 22:57:41 +00001558- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1559 its methods now allow for items objects that can be converted to
1560 an integer using operator.index().
1561
Mark Dickinson64b7e502008-07-16 09:40:03 +00001562- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1563 produced a ValueError instead of giving the correct float.
1564
Eric Smitha5fa5a22008-07-16 00:11:49 +00001565- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1566 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1567
Mark Dickinson7103aa42008-07-15 19:08:33 +00001568- Issue #3008: the float type has a new instance method 'float.hex'
1569 and a new class method 'float.fromhex' to convert floating-point
1570 numbers to and from hexadecimal strings, respectively.
1571
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001572- Issue #2235: __hash__ is once again inherited by default. To allow
1573 collections.Hashable to remain meaningful in the presence of the
1574 default hash implementation (object.__hash__), it is now possible
1575 to explicit block inheritance of hash by setting __hash__=None at
1576 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1577 level.
1578
Nick Coghlanb028f502008-07-13 14:52:36 +00001579- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1580 the parent module cannot be found while performing an absolute import.
1581 This means that an incorrectly defined __package__ attribute will
1582 now only prevent relative imports in that module rather than causing
1583 all imports from that module to fail.
1584
Nick Coghlan14ff9942008-07-08 14:21:42 +00001585- Issue #2517: Allow unicode messages in Exceptions again by correctly
1586 bypassing the instance dictionary when looking up __unicode__ on
1587 new-style classes.
1588
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00001589- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
1590 set to a custom object whose write() method happens to install
1591 another file in sys.stdout.
1592
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001593- Issue #3088: Corrected a race condition in classes derived from
1594 threading.local: the first member set by a thread could be saved in
1595 another thread's dictionary.
1596
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001597- Issue #3004: Minor change to slice.indices(): the start and stop
1598 arguments are now treated identically, making the behaviour easier
1599 to describe and understand. For example, slice(None, -10,
1600 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and

Georg Brandl5cc774e2008-06-11 20:28:06 +00002056 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002057
2058 This is controlled by the configure argument ``--with-universal-archs``:
2059

2061
2062 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2063
2064 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit

Georg Brandl3ee81df2008-05-17 18:14:43 +00002118- Issue #1631171: Re-implement the 'warnings' module in C (the
2119 original Python code has been kept as backup). This will allow for
2120 using the 'warning's machinery in such places as the parser where
2121 use of pure Python code is not possible. Both the ``showarning()``
2122 and ``formatwarning()`` gain an optional 'line' argument which is
2123 not called by default for backwards-compatibility reasons. Setting
2124 ``warnings.showwarning()`` to an implementation that lacks support
2125 for the ``line`` argument will raise a DeprecationWarning.

2149
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002150- The getpass module has been improved on Unix. It now uses /dev/tty

Georg Brandl3ee81df2008-05-17 18:14:43 +00002188- Issue #2550: The approach used by client/server code for obtaining
2189 ports to listen on in network-oriented tests has been refined in an
2190 effort to facilitate running multiple instances of the entire
2191 regression test suite in parallel without issue.
2192 test_support.bind_port() has been fixed such that it will always
2193 return a unique port -- which wasn't always the case with the
2194 previous implementation, especially if socket options had been set
2195 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2196 new implementation of bind_port() will actually raise an exception
2197 if it is passed an AF_INET/SOCK_STREAM socket with either the
2198 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2199 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2200 the socket it's been passed. This currently only applies to
2201 Windows. This option prevents any other sockets from binding to the
2202 host/port we've bound to, thus removing the possibility of the
2203 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2204 when a second SOCK_STREAM socket binds and accepts to a host/port
2205 that's already been bound by another socket. The optional preferred
2206 port parameter to bind_port() has been removed. Under no
2207 circumstances should tests be hard coding ports!
2208
2209 test_support.find_unused_port() has also been introduced, which will
2210 pass a temporary socket object to bind_port() in order to obtain an
2211 unused port. The temporary socket object is then closed and
2212 deleted, and the port is returned. This method should only be used
2213 for obtaining an unused port in order to pass to an external program
2214 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2215 a parameter to a server-oriented class that doesn't give you direct
2216 access to the underlying socket used.
2217
2218 Finally, test_support.HOST has been introduced, which should be used
2219 for the host argument of any relevant socket calls (i.e. bind and
2220 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002221
2222 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002223 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002224 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2225 test_asynchat and test_socket_ssl.
2226
Georg Brandl3ee81df2008-05-17 18:14:43 +00002227 It is now possible for multiple instances of the regression test
2228 suite to run in parallel without issue.

2496
Fred Drakea8ee94b2008-03-01 02:45:07 +00002497- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002498 644. The mode is now inherited from the py file.

Georg Brandlad61bc82008-02-23 15:11:18 +00002500- Issue #2067: file.__exit__() now calls subclasses' close() method.
2501
2502- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002503
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002504- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002505 issue 215555 for a discussion.
2506
Eric Smitha73fbe72008-02-23 03:09:44 +00002507- Added the future_builtins module, which contains hex() and oct().
2508 These are the PEP 3127 version of these functions, designed to be
2509 compatible with the hex() and oct() builtins from Python 3.0. They
2510 differ slightly in their output formats from the existing, unchanged
2511 Python 2.6 builtins. The expected usage of the future_builtins
2512 module is:
2513 from future_builtins import hex, oct
2514
Eric Smith7ef40bf2008-02-20 23:34:22 +00002515- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2516 exponents for exponents with absolute value < 100. Follows C99
2517 standard. This is a change on Windows, which would use 3 digits.
2518 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2519 so that any alterations it does to the resulting string will be
2520 available in stringlib/formatter.h (for float.__format__).
2521
Eric Smith5a3c1352008-02-19 13:21:56 +00002522- Implemented PEP 3101, Advanced String Formatting. This adds a new
2523 builtin format(); a format() method for str and unicode; a
2524 __format__() method to object, str, unicode, int, long, float, and
2525 datetime; the class string.Formatter; and the C API
2526 PyObject_Format().
2527
Georg Brandl3ee81df2008-05-17 18:14:43 +00002528- Fixed several potential crashes, all caused by specially crafted
2529 __del__ methods exploiting objects in temporarily inconsistent
2530 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002531
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002532- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002533 prevent a possible crash: an Abstract Base Class would try to access
2534 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002535
Georg Brandl3ee81df2008-05-17 18:14:43 +00002536- Fixed repr() and str() of complex numbers with infinity or nan as
2537 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002539- Clear all free lists during a gc.collect() of the highest generation
2540 in order to allow pymalloc to free more arenas. Python may give back
2541 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002542
Georg Brandl3ee81df2008-05-17 18:14:43 +00002543- Issue #2045: Fix an infinite recursion triggered when printing a
2544 subclass of collections.defaultdict, if its default_factory is set
2545 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002546
Christian Heimesf75dbef2008-02-08 00:11:31 +00002547- Fixed a minor memory leak in dictobject.c. The content of the free
2548 list was not freed on interpreter shutdown.
2549
Georg Brandl3ee81df2008-05-17 18:14:43 +00002550- Limit free list of method and builtin function objects to 256
2551 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002552
Georg Brandl3ee81df2008-05-17 18:14:43 +00002553- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2554 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002555 to compact the internal free lists of pre-allocted ints and floats.
2556
Georg Brandl3ee81df2008-05-17 18:14:43 +00002557- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2558 calls. Python expected the return type int but the fork familie
2559 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002560
Georg Brandl3ee81df2008-05-17 18:14:43 +00002561- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2562 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002563
Georg Brandl3ee81df2008-05-17 18:14:43 +00002564- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2565 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002566
Georg Brandl3ee81df2008-05-17 18:14:43 +00002567- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2568 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2571 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002572
Georg Brandl3ee81df2008-05-17 18:14:43 +00002573- Patch #1473257: generator objects gain a gi_code attribute. This is
2574 the same object as the func_code attribute of the function that
2575 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002576
Georg Brandl3ee81df2008-05-17 18:14:43 +00002577- Issue #1920: "while 0" statements were completely removed by the
2578 compiler, even in the presence of an "else" clause, which is
2579 supposed to be run when the condition is false. Now the compiler
2580 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002581
Guido van Rossumeead05f2008-01-24 18:21:02 +00002582- A few crashers fixed: weakref_in_del.py (issue #1377858);
2583 loosing_dict_ref.py (issue #1303614, test67.py);
2584 borrowed_ref_[34].py (not in tracker).
2585
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002586- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002587 suppressed while an extension is loaded by calling SetErrorMode in
2588 dynload_win.c. The error is still reported properly.
2589
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002591 several extension methods and modules do not work without unicode
2592 support.
2593
Georg Brandl26543b12008-01-21 18:36:51 +00002594- Issue #1882: when compiling code from a string, encoding cookies in the
2595 second line of code were not always recognized correctly.
2596
Georg Brandl14404b62008-01-19 19:27:05 +00002597- Issue #1679: "0x" was taken as a valid integer literal.
2598
Georg Brandl6caad7d2008-01-26 14:19:22 +00002599- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002600 added.
2601
Christian Heimesc94e2b52008-01-14 04:13:37 +00002602- sys.float_info / PyFloat_GetInfo: The floating point information
2603 object was converted from a dict to a specialized structseq object.
2604
Georg Brandl3ee81df2008-05-17 18:14:43 +00002605- Patch #1816: Added sys.flags structseq. It exposes the status of
2606 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002607
Georg Brandl3ee81df2008-05-17 18:14:43 +00002608- Objects/structseq.c: Implemented new structseq representation. The
2609 patch makes structseqs (e.g. the return value of os.stat) more
2610 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002611
Georg Brandl3ee81df2008-05-17 18:14:43 +00002612- Patch #1700288: added a type attribute cache that caches method

Georg Brandl3ee81df2008-05-17 18:14:43 +00002624- Improve some exception messages when Windows fails to load an
2625 extension module. Now we get for example '%1 is not a valid Win32
2626 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00002633- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002634 and INF. float("nan"), float("inf") and float("-inf") now work on
2635 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002636
Georg Brandl3ee81df2008-05-17 18:14:43 +00002637- Compiler now generates simpler and faster code for dictionary
2638 literals. The oparg for BUILD_MAP now indicates an estimated
2639 dictionary size. There is a new opcode, STORE_MAP, for adding
2640 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002669- Patch #1739468: Directories and zipfiles containing a __main__.py
2670 file can now be directly executed by passing their name to the
2671 interpreter. The directory/zipfile is automatically inserted as the
2672 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002673
Georg Brandl3ee81df2008-05-17 18:14:43 +00002674- Issue #1265: Fix a problem with sys.settrace, if the tracing
2675 function uses a generator expression when at the same time the
2676 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002677
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002678- sets and frozensets now have an isdisjoint() method.

2683
Georg Brandl3ee81df2008-05-17 18:14:43 +00002684- The enumerate() builtin function is no longer bounded to sequences
2685 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2686 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002687
Georg Brandl3ee81df2008-05-17 18:14:43 +00002688- Issue #1686386: Tuple's tp_repr did not take into account the
2689 possibility of having a self-referential tuple, which is possible
2690 from C code. Nor did object's tp_str consider that a type's tp_str
2691 could do something that could lead to an inifinite recursion.
2692 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2693 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002694
Georg Brandl3ee81df2008-05-17 18:14:43 +00002695- Issue #1164: It was possible to trigger deadlock when using the
2696 'print' statement to write to a file since the GIL was not released
2697 as needed. Now PyObject_Print() does the right thing along with
2698 various tp_print implementations of the built-in types and those in
2699 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Issue #1147: Exceptions were directly allowing string exceptions in
2702 their throw() method even though string exceptions no longer
2703 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002704
Georg Brandl3ee81df2008-05-17 18:14:43 +00002705- Issue #1096: Prevent a segfault from getting the repr of a very
2706 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002707
Brett Cannon1e534b52007-09-07 04:18:30 +00002708- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002709 PyObject_Call() never calling back out to Python code to trigger
2710 recursion depth updates/checks. Required the creation of a static
2711 RuntimeError instance in case normalizing an exception put the
2712 recursion check value past its limit. Fixes crashers
2713 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002714

Neal Norwitz0ac60192007-05-27 04:08:54 +00002728- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002729 __*__ attributes. (Some already existed, e.g., __doc__ and
2730 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002731
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002732- Add -3 option to the interpreter to warn about features that are
2733 deprecated and will be changed/removed in Python 3.0.
2734
Georg Brandl2134e752007-05-21 20:34:16 +00002735- Patch #1686487: you can now pass any mapping after '**' in function
2736 calls.
2737
Collin Winter62903052007-05-18 23:11:24 +00002738- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002739 "except E as target:". This is to provide forwards compatibility
2740 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002741
Brett Cannon229cee22007-05-05 01:34:02 +00002742- Deprecate BaseException.message as per PEP 352.
2743
Georg Brandl3ee81df2008-05-17 18:14:43 +00002744- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002745 inherited from a builtin base.
2746
Vinay Sajip8549ce32007-05-06 17:53:37 +00002747- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002748 setting a plain string, ie don't expand to single letter identifiers.
2749
Raymond Hettinger13936692007-04-11 18:40:58 +00002750- Request #1191699: Slices can now be pickled.
2751
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002752- Request #1193128: str.translate() now allows a None argument for
2753 translations that only remove characters without re-mapping the
2754 remaining characters.
2755
Georg Brandl5cb76c12007-03-21 09:00:39 +00002756- Patch #1682205: a TypeError while unpacking an iterable is no longer

2760
Guido van Rossum143b5642007-03-23 04:58:42 +00002761- Bug #1683368: The object.__init__() and object.__new__() methods are
2762 now stricter in rejecting excess arguments. The only time when
2763 either allows excess arguments is when it is not overridden and the
2764 other one is. For backwards compatibility, when both are
2765 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002766 warning later). Also, type.__init__() insists on the same signature
2767 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002768
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2770 object to complex using its __complex__() method before falling back
2771 to the __float__() method. Therefore, the functions in the cmath
2772 module now can operate on objects that define a __complex__()
2773 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002774
Georg Brandl3ee81df2008-05-17 18:14:43 +00002775- Patch #1623563: allow __class__ assignment for classes with
2776 __slots__. The old and the new class are still required to have the
2777 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002778

2783 ``object.__reduce_ex__()`` is called with an object that is faking
2784 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002785
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786- Patch #1680015: Don't modify __slots__ tuple if it contains an

2790
Georg Brandl7b9c5552007-03-12 14:30:05 +00002791- Bug #1678647: write a newline after printing an exception in any
2792 case, even when converting the value to a string failed.
2793
Georg Brandl871f1bc2007-03-12 13:17:36 +00002794- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002795 its argument, if it exists. If not, it will work like before. This
2796 allows customizing the output of dir() in the presence of a
2797 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002798
Collin Winter276887b2007-03-12 16:11:39 +00002799- Patch #922167: Python no longer segfaults when faced with infinitely

Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Patch #1491866: change the complex() constructor to allow
2806 parthensized forms. This means complex(repr(x)) now works instead of
2807 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002808
Georg Brandlaa2321b2007-03-07 00:40:28 +00002809- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002810 makes the filenames the warning module prints much more sensible
2811 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00002812
Georg Brandl49aafc92007-03-07 00:34:46 +00002813- Variant of patch #697613: don't exit the interpreter on a SystemExit
2814 exception if the -i command line option or PYTHONINSPECT environment

Georg Brandl0fca97a2007-03-05 22:28:08 +00002824- Patch #1674228: when assigning a slice (old-style), check for the
2825 sq_ass_slice instead of the sq_slice slot.
2826
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827- When printing an unraisable error, don't print exceptions. before
2828 the name. This duplicates the behavior whening normally printing
2829 exceptions.

2886
Armin Rigo7ccbca92006-10-04 12:17:45 +00002887- A number of places, including integer negation and absolute value,

3454 TestCase and TestSuite subclasses (not instances) are no longer
3455 accepted in TestSuite.addTest(). This should cause no

3457 -- the failure just occurred later, with a more cumbersome
3458 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003739- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3740 with RFC 3207 and forgets any knowledge obtained from the server not
3741 obtained from the TLS negotiation itself. Patch contributed by Bill
3742 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003743
Georg Brandl3ee81df2008-05-17 18:14:43 +00003744- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003745 that the SMTP.starttls() caller no longer needs to call ehlo()
3746 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003747 does not claim to support starttls. Adds the
3748 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3829 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3830 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003832

Georg Brandl3ee81df2008-05-17 18:14:43 +00003847 time so that opening a database previously created with the DB_DUP
3848 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3849 opens. Specifically: dictionary assignment to a DB object will
3850 replace all values for a given key when the database allows
3851 duplicate values. DB users should use DB.put(k, v) when they want
3852 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003853

3859 characters with ASCII value less than 32. Also, it correctly quotes
3860 dots only if they occur on a single line, as opposed to the previous
3861 behavior of quoting dots if they are the second character of any
3862 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003863

4133 default, this option is turned-off. It should only be enabled in
4134 debugged, performance critical applications.

4185-----
4186
Georg Brandl3ee81df2008-05-17 18:14:43 +00004187- Unified naming convention for free lists and their limits. All free
4188 lists in Object/ are named ``free_list``, the counter ``numfree``
4189 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4190 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004191
Georg Brandl3ee81df2008-05-17 18:14:43 +00004192- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4193 to ``PyTuple_SetItem``, it can be used to populate a brand new
4194 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004195

4203
4204- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
4205 ``PyFloat_GetInfo()`` to the float API.
4206
Georg Brandl3ee81df2008-05-17 18:14:43 +00004207- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4208 of w# format code incorrectly truncated the length to an int, even
4209 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4210 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004211
Georg Brandl3ee81df2008-05-17 18:14:43 +00004212- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4230- Fix some leftovers from the conversion from int to Py_ssize_t
4231 (relevant to strings and sequences of more than 2**31 items).
4232
4233- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4234 outside of pystate.c and should not be necessary.
4235
Georg Brandl3ee81df2008-05-17 18:14:43 +00004236- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4237 absolute imports. In earlier versions they might have used relative
4238 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004239
Georg Brandl3ee81df2008-05-17 18:14:43 +00004240- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4241 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004242
Georg Brandl3ee81df2008-05-17 18:14:43 +00004243- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

4251 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
4252 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
4253 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00004254

Georg Brandl3ee81df2008-05-17 18:14:43 +00004268- Removed the macfs module. It had been deprecated since Python 2.5.
4269 This lead to the deprecation of macostools.touched() as it relied
4270 solely on macfs and was a no-op under OS X.
