28 could crash in many places because of the PyByteArray_AS_STRING() macro
29 returning NULL. The macro now returns a statically allocated empty
30 string instead.
31

72 type is specified. Patch by Brian Curtin.
73
Antoine Pitrouca5a06a2010-01-27 21:48:46 +000074- Issue #6939: Fix file I/O objects in the `io` module to keep the original
75 file position when calling `truncate()`. It would previously change the
76 file position to the given argument, which goes against the tradition of
77 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
78
Benjamin Peterson00b90512010-01-25 03:35:04 +000079- Issue #7773: Fix an UnboundLocalError in platform.linux_distribution() when

99
Tarek Ziadé06426fc2010-01-11 22:54:57 +0000100- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

110
Antoine Pitrou0b074572010-01-08 19:21:34 +0000111- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
112 renaming of `cPickle` to `pickle`. The warning was annoying since there's
113 no alternative to cPickle if you care about performance. Patch by Florent
114 Xicluna.
115
Antoine Pitrou8dba7272010-01-07 18:04:12 +0000116- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

123 the Distutils upload command to avoid an error when PyPI reads it.
124 This occurs on long passwords. Initial patch by JP St. Pierre.
125
Senthil Kumaran81163642009-12-20 06:32:46 +0000126- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by

151
Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000152- Issue #7318: multiprocessing now uses a timeout when it fails to establish
153 a connection with another process, rather than looping endlessly. The

155 local connections.
156
Antoine Pitrouc747d3a2009-11-09 16:47:50 +0000157- Issue #7282: Fix a memory leak when an RLock was used in a thread other
158 than those started through `threading.Thread` (for example, using
159 `thread.start_new_thread()`.
160
Antoine Pitrou4fb961c2009-11-05 13:44:28 +0000161- Issue #7264: Fix a possible deadlock when deallocating thread-local objects

170 LP64 platforms (most 64-bit Linux, bsd, unix systems).
171
Gregory P. Smith6da85f92009-11-01 18:31:13 +0000172- Issue #7246 & Issue #7208: getpass now properly flushes input before
173 reading from stdin so that existing input does not confuse it and
174 lead to incorrect entry or an IOError. It also properly flushes it
175 afterwards to avoid the terminal echoing the input afterwards on
176 OSes such as Solaris.

182 sure that they accept an int or long as the second argument. Also
183 fix buggy handling of large arguments (those with coefficient longer
184 than the current precision) in shift and rotate.
185
R. David Murray7034db32009-10-27 23:39:06 +0000186- Issue #7082: When falling back to the MIME 'name' parameter, the
187 correct place to look for it is the Content-Type header.
188
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000189- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
190 larger than emax.
191
Antoine Pitrouf3a0ff62009-10-27 17:46:09 +0000192- Issue #7205: Fix a possible deadlock when using a BZ2File object from
193 several threads at once.
194
Mark Dickinson5e672d02009-10-27 16:54:45 +0000195- Issue #7048: Force Decimal.logb to round its result when that result
196 is too large to fit in the current precision.
197
Matthias Kloseb9ba2bb2010-01-16 10:31:22 +0000198- Issue #1488943: difflib.Differ() doesn't always add hints for tab characters

Ezio Melotti05327832010-01-16 18:43:14 +0000200- Issue #5037: Proxy the __unicode__ special method to __unicode__ instead of

742 object also got a new readonly attribute ``closefd``.
743
Georg Brandlfa71a902008-12-05 09:08:28 +0000744- Issue #3689: The list reversed iterator now supports __length_hint__

1115What's New in Python 2.6.1
1116==========================
1117
1118*Release date: 04-Dec-2008*
1119
1120Core and Builtins
1121-----------------
1122
1123- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1124 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1125 instead of throwing a MemoryError.
1126
1127- Issue #4367: Python would segfault during compiling when the unicodedata
1128 module couldn't be imported and \N escapes were present.
1129
1130- Issue #4348: Some bytearray methods returned that didn't cause any change to
1131 the bytearray, returned the same bytearray instead of a copy.
1132
1133- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1134
1135- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1136
1137- Issue #4048: The parser module now correctly validates relative imports.
1138
1139- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1140 exec statement.

1142- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1143 method does not return iterators for the 4th and 5th items.
1144
1145- Issue #4209: Enabling unicode_literals and the print_function in the same
1146 __future__ import didn't work.
1147
1148- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1149 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1150 really executed because I cannot move to such directory on win2k)
1151
1152- Issue #4069: When set.remove(element) is used with a set element, the element
1153 is temporarily replaced with an equivalent frozenset. But the eventual
1154 KeyError would always report the empty frozenset([]) as the missing key. Now
1155 it correctly refers to the initial element.
1156
1157- Fixed C99 style comments in several files. Python is now C89 compatible
1158 again.

1302Core and Builtins
1303-----------------
1304
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00001305- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
1306
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001307- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1308 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1309 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1310 ``printf`` function, whereas PyString_FromFormat has an independent
1311 implementation and uses "%zd" on all platforms for size_t values.
1312 This makes a difference on win64, where ``printf`` needs "%Id" to display
1313 64bit values.
1314
Benjamin Peterson97179b02008-09-09 20:55:01 +00001315- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1316 error.
1317
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001318- Issue #3777: long() applied to a float object now always return a long
1319 object; previously an int would be returned for small values. the __long__
1320 method is allowed to return either an int or a long, but the behaviour of
1321 float objects should not change to respect backward compatibility.
1322
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001323- Issue #3751: str.rpartition would perform a left-partition when called with
1324 a unicode argument.
1325
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001326- Issue #3683: Fix compilation when --without-threads is given.
1327
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001328- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001329 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001330 was correctly parsed but parsing of subsequent arguments failed.
1331
Vinay Sajip35e3b032008-09-01 14:33:59 +00001332- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001333 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1334 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1335 when given a tuple of classes as second argument, were looking up
1336 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1337 type object.
1338
Neal Norwitz18aa3882008-08-24 05:04:52 +00001339- Fix crashes on memory allocation failure found with failmalloc.
1340
1341- Fix memory leaks found with valgrind and update suppressions file.
1342
1343- Fix compiler warnings in opt mode which would lead to invalid memory reads.
1344
1345- Fix problem using wrong name in decimal module reported by pychecker.
1346
Christian Heimes7d4c3172008-08-22 19:47:25 +00001347- Silenced another compiler warning about a used but not defined
1348 function 'stringlib_contains_obj'.
1349
Benjamin Peterson712ee922008-08-24 18:10:20 +00001350- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
1351 ``__delslice__``.
1352
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00001353- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
1354 library targets in the Makefile.
1355
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001356- Issue #1204: The configure script now tests for additional libraries
1357 that may be required when linking against readline. This fixes issues
1358 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
1359

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00001368- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
1369 stack usage in the case of deeply nested objects.
1370

Nick Coghland2e09382008-09-11 12:11:06 +00001375- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
1376 silent misbehaviour when a single instance is nested in multiple
1377 with statements, or when the methods are invoked in the wrong order.
1378
Vinay Sajip844f7412008-09-09 13:42:08 +00001379- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
1380
Nick Coghland2e09382008-09-11 12:11:06 +00001381- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00001382 return a list or None rather than a custom object.
1383
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00001384- Issue #1638033: Cookie.Morsel gained the httponly attribute.

1391 its symbolic link.
1392
Vinay Sajip65d66e12008-09-04 07:31:21 +00001393- Issue #3772: Fixed regression problem in StreamHandler.emit().

1408 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1409 for catch_warnings() also led to an improvement in the raising of a
1410 DeprecationWarning related to warnings.warn_explicit().
1411
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001412- The deprecation warnings for the old camelCase threading API were removed.
1413

Benjamin Peterson37346b22008-08-23 20:27:43 +00001429Extension Modules
1430-----------------
1431
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001432- Issue #2975: When compiling several extension modules with Visual Studio 2008

1438
Gerhard Häringef2276b2008-09-12 13:54:06 +00001439- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
1440
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001441- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all

Nick Coghland2e09382008-09-11 12:11:06 +00001451- Issue #3781: Add test.test_support.check_warnings() as a convenience
1452 wrapper for warnings.catch_warnings() that makes it easier to check
1453 that expected warning messages are being reported.
1454
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001455- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001473What's New in Python 2.6 beta 3?
1474================================
1475
Barry Warsaw07a4a382008-08-21 01:15:08 +00001476*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001477
1478Core and Builtins
1479-----------------
1480
Guido van Rossumf8402962008-08-20 15:01:50 +00001481- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1482 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1483 extensions do not automatically benefit from the class attribute
1484 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1485 to their tp_flags field if they care. This is a backwards
1486 compatibility feature; in 3.0, all types will use the cache by
1487 default.
1488
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001489- Keyword arguments can now follow starred arguments. (``f(a, *args,
1490 keyword=23)`` is now valid syntax.)
1491
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001492- ctypes function pointers that are COM methods have a boolean True
1493 value again.
1494
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001495- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1496 by denying s# to parse objects that have a releasebuffer procedure,
1497 and introducing s*.
1498
Georg Brandl1e13ea92008-08-11 09:07:59 +00001499- Issue #3537: Fix an assertion failure when an empty but presized dict
1500 object was stored in the freelist.
1501
Mark Dickinsonb6467572008-08-04 21:30:09 +00001502- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1503 ValueError consistently across platforms.
1504
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001505- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1506 (64bit Unix, for example), unichr() would truncate its argument and return
1507 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1508
Neal Norwitze7d8be82008-07-31 17:17:14 +00001509- Apply security patches from Apple.
1510
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001511- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1512 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1513
Antoine Pitrou92f82162008-07-25 22:22:08 +00001514- Issue #1819: function calls with several named parameters are now on
1515 average 35% faster (as measured by pybench).
1516
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001517- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1518 the python debugger steps into a class statement: the free variables (local
1519 variables defined in an outer scope) would be deleted from the outer scope.
1520
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001521- Issue #2620: Overflow checking when allocating or reallocating memory
1522 was not always being done properly in some python types and extension
1523 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1524 all been updated to perform better checks and places in the code that
1525 would previously leak memory on the error path when such an allocation
1526 failed have been fixed.
1527
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001528Library
1529-------
1530
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001531- Issue #3612: Added some missing basic types in ctypes.wintypes.
1532
Benjamin Petersone977ad42008-08-20 01:42:01 +00001533- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1534 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1535
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001536- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1537 version reported by these tools does not necessarily follow the python
1538 version numbering scheme, so the module is less strict when parsing it.
1539
Nick Coghlanf70385a2008-08-18 12:42:46 +00001540- Issue #2235: Added Py3k warnings for types which will become unhashable
1541 under the stricter __hash__ inheritance rules in 3.0. Several types
1542 which did not meet the rules for hash invariants and were already
1543 unhashable in 3.0 have now been explicitly flagged as unhashable in
1544 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1545 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1546
Brett Cannon88f801d2008-08-18 00:46:22 +00001547- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1548 imported into the module but exposed as part of the module's API.
1549
Brett Cannon7b96f072008-08-18 00:41:11 +00001550- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1551
Brett Cannon46225e72008-08-18 00:36:52 +00001552- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001554- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1555
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001556- Issue #3575: Incremental decoder's decode function now takes bytearray
1557 by using 's*' instead of 't#'.
1558
Jesus Cea585ad8a2009-07-02 15:37:21 +00001559- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001560 fails unicode conversion on 2nd parameter. (windows only)
1561
Facundo Batista94f243a2008-08-17 03:38:39 +00001562- Issue 2464. urllib2 now supports a malformation in the URL received
1563 in a redirect.
1564
Brett Cannonabe423e2008-08-16 21:47:07 +00001565- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001566 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001567
Facundo Batistaeb90b782008-08-16 14:44:07 +00001568- Issue #2776: fixed small issue when handling an URL with double slash
1569 after a 302 response in the case of not going through a proxy.
1570
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001571- Issue #2676: in the email package, content-type parsing was hanging on
1572 pathological input because of quadratic or exponential behaviour of a
1573 regular expression.
1574
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001575- Issue #3476: binary buffered reading through the new "io" library is now
1576 thread-safe.
1577
Brett Cannonbf3157b2008-08-14 05:00:03 +00001578- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1579 since mimetools itself is deprecated. Because modules are cached, all
1580 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1581
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001582- Issue #3134: shutil referenced undefined WindowsError symbol.
1583
Robert Schuppenies14646332008-08-10 11:01:53 +00001584- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1585 menu entries were not deleted.
1586
Brett Cannon83e81842008-08-09 23:30:55 +00001587- Copied the implementation of reduce() to _functools.reduce() to have a
1588 version that did not raise a DeprecationWarning under -3.

Antoine Pitroude781a42008-08-09 12:43:23 +00001616 asking for a specific length. This problem only affected files opened

1660
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00001661- Issue #643841: The language reference now provides more detailed

1673-----------------
1674
Georg Brandl3e483f62008-07-16 22:57:41 +00001675- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1676 its methods now allow for items objects that can be converted to
1677 an integer using operator.index().
1678
Mark Dickinson64b7e502008-07-16 09:40:03 +00001679- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1680 produced a ValueError instead of giving the correct float.
1681
Eric Smitha5fa5a22008-07-16 00:11:49 +00001682- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1683 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1684
Mark Dickinson7103aa42008-07-15 19:08:33 +00001685- Issue #3008: the float type has a new instance method 'float.hex'
1686 and a new class method 'float.fromhex' to convert floating-point
1687 numbers to and from hexadecimal strings, respectively.
1688
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001689- Issue #2235: __hash__ is once again inherited by default. To allow
1690 collections.Hashable to remain meaningful in the presence of the
1691 default hash implementation (object.__hash__), it is now possible
1692 to explicit block inheritance of hash by setting __hash__=None at
1693 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1694 level.
1695
Nick Coghlanb028f502008-07-13 14:52:36 +00001696- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1697 the parent module cannot be found while performing an absolute import.
1698 This means that an incorrectly defined __package__ attribute will
1699 now only prevent relative imports in that module rather than causing
1700 all imports from that module to fail.
1701
Nick Coghlan14ff9942008-07-08 14:21:42 +00001702- Issue #2517: Allow unicode messages in Exceptions again by correctly

1707 set to a custom object whose write() method happens to install
1708 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00001710- Issue #3088: Corrected a race condition in classes derived from
1711 threading.local: the first member set by a thread could be saved in
1712 another thread's dictionary.
1713
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001714- Issue #3004: Minor change to slice.indices(): the start and stop
1715 arguments are now treated identically, making the behaviour easier
1716 to describe and understand. For example, slice(None, -10,
1717 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1718 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1719 10, -1).
1720
Georg Brandl278fc502008-07-19 12:46:12 +00001721- Issue #3219: Calling a function with repeated keyword arguments,
1722 f(a=2, a=23), would not cause a syntax error. This was a regression
1723 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001724
Georg Brandl278fc502008-07-19 12:46:12 +00001725- Issue #2862: Make int and float freelist management consistent with
1726 other freelists. Changes their CompactFreeList apis into

1733 api functions without holding the GIL, which could lead to a fatal
1734 error when they failed.
1735
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001736- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001761- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1762 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001763 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001764 content-length. The problem had been corrected in the 2.4 branch, but never
1765 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001780- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

1782
Brett Cannon8bb8fa52008-07-02 01:57:08 +00001783- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

2168
Brett Cannonb61d8012008-05-11 23:39:04 +00002169- ``Lib/lib-old`` is now added to sys.path.
2170
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002171- On MacOS X it is now possible to install the framework in 64-bit
2172 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002173 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002174
2175 This is controlled by the configure argument ``--with-universal-archs``:
2176
2177 - ``--with-universal-archs=all``: install 4-way universal
2178
2179 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2180
2181 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2182
2183 This option should be used in combination with ``--enable-universalsdk=``.
2184
2185 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00002194
2195- The PyString functions have been renamed to PyBytes. A batch of
2196 defines were added so that the linker still sees the original
2197 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002235- Issue #1631171: Re-implement the 'warnings' module in C (the
2236 original Python code has been kept as backup). This will allow for
2237 using the 'warning's machinery in such places as the parser where
2238 use of pure Python code is not possible. Both the ``showarning()``
2239 and ``formatwarning()`` gain an optional 'line' argument which is
2240 not called by default for backwards-compatibility reasons. Setting
2241 ``warnings.showwarning()`` to an implementation that lacks support
2242 for the ``line`` argument will raise a DeprecationWarning.

2266
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002267- The getpass module has been improved on Unix. It now uses /dev/tty
2268 by default and uses stderr instead of stdout. A GetPassWarning is
2269 issued when input echo cannot be controlled.
Gregory P. Smith41e30182008-04-21 21:31:08 +00002270

2282 removed and replaced by pure python code.
Amaury Forgeot d'Arc02f33b42008-04-08 23:10:07 +00002283
Georg Brandl3ee81df2008-05-17 18:14:43 +00002284- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002285 extension modules between 32 and 64 bit platforms. See the distutls

2298 so the controlled environment will more closely mirror the typical
2299 script environment. This supports setup.py scripts that refer to
2300 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002305- Issue #2550: The approach used by client/server code for obtaining
2306 ports to listen on in network-oriented tests has been refined in an
2307 effort to facilitate running multiple instances of the entire
2308 regression test suite in parallel without issue.
2309 test_support.bind_port() has been fixed such that it will always
2310 return a unique port -- which wasn't always the case with the
2311 previous implementation, especially if socket options had been set
2312 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2313 new implementation of bind_port() will actually raise an exception
2314 if it is passed an AF_INET/SOCK_STREAM socket with either the
2315 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2316 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2317 the socket it's been passed. This currently only applies to
2318 Windows. This option prevents any other sockets from binding to the
2319 host/port we've bound to, thus removing the possibility of the
2320 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2321 when a second SOCK_STREAM socket binds and accepts to a host/port
2322 that's already been bound by another socket. The optional preferred
2323 port parameter to bind_port() has been removed. Under no
2324 circumstances should tests be hard coding ports!
2325
2326 test_support.find_unused_port() has also been introduced, which will
2327 pass a temporary socket object to bind_port() in order to obtain an
2328 unused port. The temporary socket object is then closed and
2329 deleted, and the port is returned. This method should only be used
2330 for obtaining an unused port in order to pass to an external program
2331 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2332 a parameter to a server-oriented class that doesn't give you direct
2333 access to the underlying socket used.
2334
2335 Finally, test_support.HOST has been introduced, which should be used
2336 for the host argument of any relevant socket calls (i.e. bind and
2337 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002338
2339 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002340 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002341 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2342 test_asynchat and test_socket_ssl.
2343
Georg Brandl3ee81df2008-05-17 18:14:43 +00002344 It is now possible for multiple instances of the regression test
2345 suite to run in parallel without issue.

2612-----------------
2613
Fred Drakea8ee94b2008-03-01 02:45:07 +00002614- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002615 644. The mode is now inherited from the py file.

2618
2619- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002620
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002621- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002622 issue 215555 for a discussion.
2623
Eric Smitha73fbe72008-02-23 03:09:44 +00002624- Added the future_builtins module, which contains hex() and oct().
2625 These are the PEP 3127 version of these functions, designed to be
2626 compatible with the hex() and oct() builtins from Python 3.0. They
2627 differ slightly in their output formats from the existing, unchanged
2628 Python 2.6 builtins. The expected usage of the future_builtins
2629 module is:
2630 from future_builtins import hex, oct
2631
Eric Smith7ef40bf2008-02-20 23:34:22 +00002632- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2633 exponents for exponents with absolute value < 100. Follows C99
2634 standard. This is a change on Windows, which would use 3 digits.
2635 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2636 so that any alterations it does to the resulting string will be
2637 available in stringlib/formatter.h (for float.__format__).
2638
Eric Smith5a3c1352008-02-19 13:21:56 +00002639- Implemented PEP 3101, Advanced String Formatting. This adds a new
2640 builtin format(); a format() method for str and unicode; a
2641 __format__() method to object, str, unicode, int, long, float, and
2642 datetime; the class string.Formatter; and the C API
2643 PyObject_Format().
2644
Georg Brandl3ee81df2008-05-17 18:14:43 +00002645- Fixed several potential crashes, all caused by specially crafted
2646 __del__ methods exploiting objects in temporarily inconsistent
2647 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002648
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002649- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650 prevent a possible crash: an Abstract Base Class would try to access
2651 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002652

2654 real or imaginary part.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002656- Clear all free lists during a gc.collect() of the highest generation
2657 in order to allow pymalloc to free more arenas. Python may give back
2658 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002659
Georg Brandl3ee81df2008-05-17 18:14:43 +00002660- Issue #2045: Fix an infinite recursion triggered when printing a
2661 subclass of collections.defaultdict, if its default_factory is set
2662 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002663
Christian Heimesf75dbef2008-02-08 00:11:31 +00002664- Fixed a minor memory leak in dictobject.c. The content of the free
2665 list was not freed on interpreter shutdown.
2666
Georg Brandl3ee81df2008-05-17 18:14:43 +00002667- Limit free list of method and builtin function objects to 256
2668 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002669
Georg Brandl3ee81df2008-05-17 18:14:43 +00002670- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2671 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002672 to compact the internal free lists of pre-allocted ints and floats.
2673
Georg Brandl3ee81df2008-05-17 18:14:43 +00002674- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2675 calls. Python expected the return type int but the fork familie
2676 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002677
Georg Brandl3ee81df2008-05-17 18:14:43 +00002678- Issue #1678380: Fix a bug that identifies 0j and -0j when they

Georg Brandl3ee81df2008-05-17 18:14:43 +00002687- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2688 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002689
Georg Brandl3ee81df2008-05-17 18:14:43 +00002690- Patch #1473257: generator objects gain a gi_code attribute. This is
2691 the same object as the func_code attribute of the function that
2692 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002693
Georg Brandl3ee81df2008-05-17 18:14:43 +00002694- Issue #1920: "while 0" statements were completely removed by the
2695 compiler, even in the presence of an "else" clause, which is
2696 supposed to be run when the condition is false. Now the compiler
2697 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002698
Guido van Rossumeead05f2008-01-24 18:21:02 +00002699- A few crashers fixed: weakref_in_del.py (issue #1377858);
2700 loosing_dict_ref.py (issue #1303614, test67.py);
2701 borrowed_ref_[34].py (not in tracker).
2702
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002703- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002704 suppressed while an extension is loaded by calling SetErrorMode in
2705 dynload_win.c. The error is still reported properly.
2706
Georg Brandl3ee81df2008-05-17 18:14:43 +00002707- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002708 several extension methods and modules do not work without unicode
2709 support.
2710
Georg Brandl26543b12008-01-21 18:36:51 +00002711- Issue #1882: when compiling code from a string, encoding cookies in the
2712 second line of code were not always recognized correctly.
2713
Georg Brandl14404b62008-01-19 19:27:05 +00002714- Issue #1679: "0x" was taken as a valid integer literal.
2715
Georg Brandl6caad7d2008-01-26 14:19:22 +00002716- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002717 added.
2718
Christian Heimesc94e2b52008-01-14 04:13:37 +00002719- sys.float_info / PyFloat_GetInfo: The floating point information
2720 object was converted from a dict to a specialized structseq object.
2721
Georg Brandl3ee81df2008-05-17 18:14:43 +00002722- Patch #1816: Added sys.flags structseq. It exposes the status of
2723 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002724
Georg Brandl3ee81df2008-05-17 18:14:43 +00002725- Objects/structseq.c: Implemented new structseq representation. The
2726 patch makes structseqs (e.g. the return value of os.stat) more
2727 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002728
Georg Brandl3ee81df2008-05-17 18:14:43 +00002729- Patch #1700288: added a type attribute cache that caches method
2730 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002731
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002732- Bug #1776: __import__() no longer accepts filenames on any platform.
2733 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002734

2736
Georg Brandl3ee81df2008-05-17 18:14:43 +00002737- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2738 envvar and sys.dont_write_bytecode attribute. All these can be set
2739 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002740
Georg Brandl3ee81df2008-05-17 18:14:43 +00002741- Improve some exception messages when Windows fails to load an
2742 extension module. Now we get for example '%1 is not a valid Win32
2743 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002744

2748 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002749
Christian Heimes0a8143f2007-12-18 23:22:54 +00002750- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002751 and INF. float("nan"), float("inf") and float("-inf") now work on
2752 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Compiler now generates simpler and faster code for dictionary
2755 literals. The oparg for BUILD_MAP now indicates an estimated
2756 dictionary size. There is a new opcode, STORE_MAP, for adding
2757 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002786- Patch #1739468: Directories and zipfiles containing a __main__.py
2787 file can now be directly executed by passing their name to the
2788 interpreter. The directory/zipfile is automatically inserted as the
2789 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002790
Georg Brandl3ee81df2008-05-17 18:14:43 +00002791- Issue #1265: Fix a problem with sys.settrace, if the tracing
2792 function uses a generator expression when at the same time the
2793 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002794
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002795- sets and frozensets now have an isdisjoint() method.
2796

2798
Neal Norwitz44f326e2007-10-05 05:29:17 +00002799- Fix warnings found by the new version of the Coverity checker.
2800
Georg Brandl3ee81df2008-05-17 18:14:43 +00002801- The enumerate() builtin function is no longer bounded to sequences
2802 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2803 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002804
Georg Brandl3ee81df2008-05-17 18:14:43 +00002805- Issue #1686386: Tuple's tp_repr did not take into account the
2806 possibility of having a self-referential tuple, which is possible
2807 from C code. Nor did object's tp_str consider that a type's tp_str
2808 could do something that could lead to an inifinite recursion.
2809 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2810 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002811
Georg Brandl3ee81df2008-05-17 18:14:43 +00002812- Issue #1164: It was possible to trigger deadlock when using the
2813 'print' statement to write to a file since the GIL was not released
2814 as needed. Now PyObject_Print() does the right thing along with
2815 various tp_print implementations of the built-in types and those in
2816 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002817
Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Issue #1147: Exceptions were directly allowing string exceptions in
2819 their throw() method even though string exceptions no longer
2820 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002821
Georg Brandl3ee81df2008-05-17 18:14:43 +00002822- Issue #1096: Prevent a segfault from getting the repr of a very
2823 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002824
Brett Cannon1e534b52007-09-07 04:18:30 +00002825- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002826 PyObject_Call() never calling back out to Python code to trigger
2827 recursion depth updates/checks. Required the creation of a static
2828 RuntimeError instance in case normalizing an exception put the
2829 recursion check value past its limit. Fixes crashers
2830 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002831
Georg Brandl3ee81df2008-05-17 18:14:43 +00002832- Patch #1031213: Decode source line in SyntaxErrors back to its

2836 with %G.
2837
Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00002845- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002846 __*__ attributes. (Some already existed, e.g., __doc__ and
2847 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002848
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002849- Add -3 option to the interpreter to warn about features that are
2850 deprecated and will be changed/removed in Python 3.0.
2851
Georg Brandl2134e752007-05-21 20:34:16 +00002852- Patch #1686487: you can now pass any mapping after '**' in function
2853 calls.
2854
Collin Winter62903052007-05-18 23:11:24 +00002855- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856 "except E as target:". This is to provide forwards compatibility
2857 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002858
Brett Cannon229cee22007-05-05 01:34:02 +00002859- Deprecate BaseException.message as per PEP 352.
2860
Georg Brandl3ee81df2008-05-17 18:14:43 +00002861- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002862 inherited from a builtin base.
2863
Vinay Sajip8549ce32007-05-06 17:53:37 +00002864- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002865 setting a plain string, ie don't expand to single letter identifiers.
2866
Raymond Hettinger13936692007-04-11 18:40:58 +00002867- Request #1191699: Slices can now be pickled.
2868
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002869- Request #1193128: str.translate() now allows a None argument for
2870 translations that only remove characters without re-mapping the
2871 remaining characters.
2872
Georg Brandl5cb76c12007-03-21 09:00:39 +00002873- Patch #1682205: a TypeError while unpacking an iterable is no longer
2874 masked by a generic one with the message "unpack non-sequence".
2875
Neal Norwitzaa754b72007-03-21 06:39:48 +00002876- Remove unused file Python/fmod.c.
2877
Guido van Rossum143b5642007-03-23 04:58:42 +00002878- Bug #1683368: The object.__init__() and object.__new__() methods are
2879 now stricter in rejecting excess arguments. The only time when
2880 either allows excess arguments is when it is not overridden and the
2881 other one is. For backwards compatibility, when both are
2882 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002883 warning later). Also, type.__init__() insists on the same signature
2884 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002885
Georg Brandl3ee81df2008-05-17 18:14:43 +00002886- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2887 object to complex using its __complex__() method before falling back
2888 to the __float__() method. Therefore, the functions in the cmath
2889 module now can operate on objects that define a __complex__()
2890 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002891
Georg Brandl3ee81df2008-05-17 18:14:43 +00002892- Patch #1623563: allow __class__ assignment for classes with
2893 __slots__. The old and the new class are still required to have the
2894 same slot names.

2900 ``object.__reduce_ex__()`` is called with an object that is faking
2901 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002902
Georg Brandl3ee81df2008-05-17 18:14:43 +00002903- Patch #1680015: Don't modify __slots__ tuple if it contains an

2907
Georg Brandl7b9c5552007-03-12 14:30:05 +00002908- Bug #1678647: write a newline after printing an exception in any
2909 case, even when converting the value to a string failed.
2910
Georg Brandl871f1bc2007-03-12 13:17:36 +00002911- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002912 its argument, if it exists. If not, it will work like before. This
2913 allows customizing the output of dir() in the presence of a
2914 __getattr__().

Collin Winter276887b2007-03-12 16:11:39 +00002916- Patch #922167: Python no longer segfaults when faced with infinitely
2917 self-recursive reload() calls (as reported by bug #742342).
2918
Georg Brandl3ee81df2008-05-17 18:14:43 +00002919- Patch #1675981: remove unreachable code from ``type.__new__()``

Facundo Batistad918a652007-04-24 13:54:38 +00003437- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003438 the client's request was successfully received, understood, and
3439 accepted. Now in these cases no error is raised in urllib (issue
3440 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003441

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003448- Added a timeout parameter to the constructor of other protocols
3449 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3450 work started with create_connection() and timeout in httplib, and
3451 closes patch #723312.
3452
Vinay Sajip8549ce32007-05-06 17:53:37 +00003453- Patch #1676823: Added create_connection() to socket.py, which may be

Facundo Batista07c78be2007-03-23 18:54:07 +00003456

3477
Georg Brandlf66b6032007-03-14 08:27:52 +00003478- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003479 AttributeError instead of an IOError when the server's response
3480 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003481
Georg Brandl3ee81df2008-05-17 18:14:43 +00003482- Patch #957650: "%var%" environment variable references are now
3483 properly expanded in ntpath.expandvars(), also "~user" home

Georg Brandl3ee81df2008-05-17 18:14:43 +00003486- Patch #1429539: pdb now correctly initializes the __main__ module
3487 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003488 correctly now.
3489
Georg Brandlbad6f192007-03-13 21:32:56 +00003490- The nonobvious commands.getstatus() function is now deprecated.

3496
Georg Brandl3ee81df2008-05-17 18:14:43 +00003497- Patch #1530482: add pydoc.render_doc() which returns the
3498 documentation for a thing instead of paging it to stdout, which
3499 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003500

Georg Brandl9e6b4702007-03-13 18:15:41 +00003510- Patch #1581073: add a flag to textwrap that prevents the dropping of

3512
Georg Brandl92a6bae2007-03-13 17:43:32 +00003513- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003514 are set for invalid interpolation sequences that would lead to
3515 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003516

3529
Georg Brandl94fe3f52007-03-13 09:32:11 +00003530- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003531 field names in its exception message if you try to write a record
3532 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003550

3558 returned string up to the first NUL character.

3569
Georg Brandl3ee81df2008-05-17 18:14:43 +00003570- unittest now verifies more of its assumptions. In particular,
3571 TestCase and TestSuite subclasses (not instances) are no longer
3572 accepted in TestSuite.addTest(). This should cause no
3573 incompatibility since it never made sense with ordinary subclasses
3574 -- the failure just occurred later, with a more cumbersome
3575 exception.

3584 given a unicode argument and os.listdir() returns unicode filenames.
3585
Georg Brandl3ee81df2008-05-17 18:14:43 +00003586- Patch #1673619: setup.py identifies extension modules it doesn't

3588 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003964 time so that opening a database previously created with the DB_DUP
3965 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3966 opens. Specifically: dictionary assignment to a DB object will
3967 replace all values for a given key when the database allows
3968 duplicate values. DB users should use DB.put(k, v) when they want
3969 to store duplicates; not DB[k] = v.

3976 characters with ASCII value less than 32. Also, it correctly quotes
3977 dots only if they occur on a single line, as opposed to the previous
3978 behavior of quoting dots if they are the second character of any
3979 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003980
