52
Antoine Pitrou9aece752009-10-27 12:48:52 +000053- Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which

56
Antoine Pitrou686c9ad2009-10-27 12:56:06 +000057- Issue #7084: Fix a (very unlikely) crash when printing a list from one

70 type is specified. Patch by Brian Curtin.
71
Antoine Pitrouca5a06a2010-01-27 21:48:46 +000072- Issue #6939: Fix file I/O objects in the `io` module to keep the original
73 file position when calling `truncate()`. It would previously change the
74 file position to the given argument, which goes against the tradition of
75 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

79
Tarek Ziadé495517c2010-01-24 00:57:20 +000080- Issue #7748: Since unicode values are supported for some metadata options

97
Tarek Ziadé06426fc2010-01-11 22:54:57 +000098- Issue #5372: Drop the reuse of .o files in Distutils' ccompiler (since

108
Antoine Pitrou0b074572010-01-08 19:21:34 +0000109- Issue #7092: Remove py3k warning when importing cPickle. 2to3 handles
110 renaming of `cPickle` to `pickle`. The warning was annoying since there's
111 no alternative to cPickle if you care about performance. Patch by Florent
112 Xicluna.
113
Antoine Pitrou8dba7272010-01-07 18:04:12 +0000114- Issue #7455: Fix possible crash in cPickle on invalid input. Patch by

123
Senthil Kumaran81163642009-12-20 06:32:46 +0000124- Issue #7231: urllib2 cannot handle https with proxy requiring auth. Patch by
125 Tatsuhiro Tsujikawa.
126
Benjamin Peterson95671122009-12-13 17:34:05 +0000127- Issue #7348: StringIO.StringIO.readline(-1) now acts as if it got no argument

149
Antoine Pitroueaaf66c2009-11-13 22:33:27 +0000150- Issue #7318: multiprocessing now uses a timeout when it fails to establish
151 a connection with another process, rather than looping endlessly. The

153 local connections.
154

157 `thread.start_new_thread()`.
158
Antoine Pitrou4fb961c2009-11-05 13:44:28 +0000159- Issue #7264: Fix a possible deadlock when deallocating thread-local objects

168 LP64 platforms (most 64-bit Linux, bsd, unix systems).
169
Gregory P. Smith6da85f92009-11-01 18:31:13 +0000170- Issue #7246 & Issue #7208: getpass now properly flushes input before
171 reading from stdin so that existing input does not confuse it and
172 lead to incorrect entry or an IOError. It also properly flushes it
173 afterwards to avoid the terminal echoing the input afterwards on
174 OSes such as Solaris.

180 sure that they accept an int or long as the second argument. Also
181 fix buggy handling of large arguments (those with coefficient longer
182 than the current precision) in shift and rotate.
183
R. David Murray7034db32009-10-27 23:39:06 +0000184- Issue #7082: When falling back to the MIME 'name' parameter, the
185 correct place to look for it is the Content-Type header.
186
Mark Dickinson20a7cfc2009-10-27 18:27:53 +0000187- Issue #7099: Decimal.is_normal now returns True for numbers with exponent
188 larger than emax.
189
Antoine Pitrouf3a0ff62009-10-27 17:46:09 +0000190- Issue #7205: Fix a possible deadlock when using a BZ2File object from
191 several threads at once.
192

194 is too large to fit in the current precision.
195
Matthias Kloseb9ba2bb2010-01-16 10:31:22 +0000196- Issue #1488943: difflib.Differ() doesn't always add hints for tab characters

1110What's New in Python 2.6.1
1111==========================
1112
1113*Release date: 04-Dec-2008*
1114
1115Core and Builtins
1116-----------------
1117
1118- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1119 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1120 instead of throwing a MemoryError.
1121
1122- Issue #4367: Python would segfault during compiling when the unicodedata
1123 module couldn't be imported and \N escapes were present.
1124
1125- Issue #4348: Some bytearray methods returned that didn't cause any change to
1126 the bytearray, returned the same bytearray instead of a copy.
1127
1128- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1129
1130- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1131
1132- Issue #4048: The parser module now correctly validates relative imports.
1133
1134- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1135 exec statement.

1137- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1138 method does not return iterators for the 4th and 5th items.
1139
1140- Issue #4209: Enabling unicode_literals and the print_function in the same
1141 __future__ import didn't work.
1142
1143- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1144 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1145 really executed because I cannot move to such directory on win2k)
1146
1147- Issue #4069: When set.remove(element) is used with a set element, the element
1148 is temporarily replaced with an equivalent frozenset. But the eventual
1149 KeyError would always report the empty frozenset([]) as the missing key. Now
1150 it correctly refers to the initial element.
1151
1152- Fixed C99 style comments in several files. Python is now C89 compatible
1153 again.

1303 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1304 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1305 ``printf`` function, whereas PyString_FromFormat has an independent
1306 implementation and uses "%zd" on all platforms for size_t values.
1307 This makes a difference on win64, where ``printf`` needs "%Id" to display
1308 64bit values.
1309
Benjamin Peterson97179b02008-09-09 20:55:01 +00001310- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
1311 error.
1312
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00001313- Issue #3777: long() applied to a float object now always return a long
1314 object; previously an int would be returned for small values. the __long__
1315 method is allowed to return either an int or a long, but the behaviour of
1316 float objects should not change to respect backward compatibility.
1317
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00001318- Issue #3751: str.rpartition would perform a left-partition when called with
1319 a unicode argument.
1320
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001321- Issue #3683: Fix compilation when --without-threads is given.
1322
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001323- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00001324 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00001325 was correctly parsed but parsing of subsequent arguments failed.
1326
Vinay Sajip35e3b032008-09-01 14:33:59 +00001327- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00001328 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
1329 mechanism. In the process, fix a bug where isinstance() and issubclass(),
1330 when given a tuple of classes as second argument, were looking up
1331 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1332 type object.
1333
Neal Norwitz18aa3882008-08-24 05:04:52 +00001334- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +00001342- Silenced another compiler warning about a used but not defined
1343 function 'stringlib_contains_obj'.
1344

1350
Gregory P. Smith980b99b2008-09-07 05:15:18 +00001351- Issue #1204: The configure script now tests for additional libraries
1352 that may be required when linking against readline. This fixes issues
1353 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

1403 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1404 for catch_warnings() also led to an improvement in the raising of a
1405 DeprecationWarning related to warnings.warn_explicit().

1429 without limit.
1430
Benjamin Peterson37346b22008-08-23 20:27:43 +00001431- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001468What's New in Python 2.6 beta 3?
1469================================
1470
Barry Warsaw07a4a382008-08-21 01:15:08 +00001471*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001472
1473Core and Builtins
1474-----------------
1475
Guido van Rossumf8402962008-08-20 15:01:50 +00001476- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1477 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1478 extensions do not automatically benefit from the class attribute
1479 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1480 to their tp_flags field if they care. This is a backwards
1481 compatibility feature; in 3.0, all types will use the cache by
1482 default.
1483
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001484- Keyword arguments can now follow starred arguments. (``f(a, *args,
1485 keyword=23)`` is now valid syntax.)
1486
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001487- ctypes function pointers that are COM methods have a boolean True
1488 value again.
1489
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001490- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1491 by denying s# to parse objects that have a releasebuffer procedure,
1492 and introducing s*.
1493
Georg Brandl1e13ea92008-08-11 09:07:59 +00001494- Issue #3537: Fix an assertion failure when an empty but presized dict
1495 object was stored in the freelist.
1496
Mark Dickinsonb6467572008-08-04 21:30:09 +00001497- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1498 ValueError consistently across platforms.
1499
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001500- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1501 (64bit Unix, for example), unichr() would truncate its argument and return
1502 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1503
Neal Norwitze7d8be82008-07-31 17:17:14 +00001504- Apply security patches from Apple.
1505
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001506- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1507 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1508
Antoine Pitrou92f82162008-07-25 22:22:08 +00001509- Issue #1819: function calls with several named parameters are now on
1510 average 35% faster (as measured by pybench).
1511
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001512- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1513 the python debugger steps into a class statement: the free variables (local
1514 variables defined in an outer scope) would be deleted from the outer scope.
1515
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001516- Issue #2620: Overflow checking when allocating or reallocating memory
1517 was not always being done properly in some python types and extension
1518 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1519 all been updated to perform better checks and places in the code that
1520 would previously leak memory on the error path when such an allocation
1521 failed have been fixed.

1524-------
1525
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001526- Issue #3612: Added some missing basic types in ctypes.wintypes.
1527
Benjamin Petersone977ad42008-08-20 01:42:01 +00001528- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1529 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1530
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001531- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1532 version reported by these tools does not necessarily follow the python
1533 version numbering scheme, so the module is less strict when parsing it.
1534
Nick Coghlanf70385a2008-08-18 12:42:46 +00001535- Issue #2235: Added Py3k warnings for types which will become unhashable
1536 under the stricter __hash__ inheritance rules in 3.0. Several types
1537 which did not meet the rules for hash invariants and were already
1538 unhashable in 3.0 have now been explicitly flagged as unhashable in
1539 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1540 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1541
Brett Cannon88f801d2008-08-18 00:46:22 +00001542- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1543 imported into the module but exposed as part of the module's API.
1544
Brett Cannon7b96f072008-08-18 00:41:11 +00001545- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1546
Brett Cannon46225e72008-08-18 00:36:52 +00001547- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
1548
Brett Cannon25c9d6a2008-08-17 22:10:11 +00001549- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1550
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001551- Issue #3575: Incremental decoder's decode function now takes bytearray
1552 by using 's*' instead of 't#'.
1553
Jesus Cea585ad8a2009-07-02 15:37:21 +00001554- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001555 fails unicode conversion on 2nd parameter. (windows only)
1556
Facundo Batista94f243a2008-08-17 03:38:39 +00001557- Issue 2464. urllib2 now supports a malformation in the URL received
1558 in a redirect.
1559
Brett Cannonabe423e2008-08-16 21:47:07 +00001560- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001561 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001562
Facundo Batistaeb90b782008-08-16 14:44:07 +00001563- Issue #2776: fixed small issue when handling an URL with double slash
1564 after a 302 response in the case of not going through a proxy.
1565
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001566- Issue #2676: in the email package, content-type parsing was hanging on
1567 pathological input because of quadratic or exponential behaviour of a
1568 regular expression.
1569
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001570- Issue #3476: binary buffered reading through the new "io" library is now
1571 thread-safe.
1572
Brett Cannonbf3157b2008-08-14 05:00:03 +00001573- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1574 since mimetools itself is deprecated. Because modules are cached, all
1575 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1576
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001577- Issue #3134: shutil referenced undefined WindowsError symbol.
1578
Robert Schuppenies14646332008-08-10 11:01:53 +00001579- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1580 menu entries were not deleted.
1581
Brett Cannon83e81842008-08-09 23:30:55 +00001582- Copied the implementation of reduce() to _functools.reduce() to have a
1583 version that did not raise a DeprecationWarning under -3.
1584
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001585- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1586 a MemoryError rather than silently stop the iteration.
1587
Guido van Rossum59ce9012008-08-09 14:55:34 +00001588- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1589 to _sre.compile() will now be rejected. This should not affect anybody

Antoine Pitroude781a42008-08-09 12:43:23 +00001611 asking for a specific length. This problem only affected files opened

1663================================
1664
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001665*Release date: 17-Jul-2008*

1668-----------------
1669
Georg Brandl3e483f62008-07-16 22:57:41 +00001670- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1671 its methods now allow for items objects that can be converted to
1672 an integer using operator.index().
1673
Mark Dickinson64b7e502008-07-16 09:40:03 +00001674- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1675 produced a ValueError instead of giving the correct float.
1676
Eric Smitha5fa5a22008-07-16 00:11:49 +00001677- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1678 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1679
Mark Dickinson7103aa42008-07-15 19:08:33 +00001680- Issue #3008: the float type has a new instance method 'float.hex'
1681 and a new class method 'float.fromhex' to convert floating-point
1682 numbers to and from hexadecimal strings, respectively.
1683
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001684- Issue #2235: __hash__ is once again inherited by default. To allow
1685 collections.Hashable to remain meaningful in the presence of the
1686 default hash implementation (object.__hash__), it is now possible
1687 to explicit block inheritance of hash by setting __hash__=None at
1688 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
1689 level.
1690
Nick Coghlanb028f502008-07-13 14:52:36 +00001691- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1692 the parent module cannot be found while performing an absolute import.
1693 This means that an incorrectly defined __package__ attribute will
1694 now only prevent relative imports in that module rather than causing
1695 all imports from that module to fail.
1696
Nick Coghlan14ff9942008-07-08 14:21:42 +00001697- Issue #2517: Allow unicode messages in Exceptions again by correctly

1707 another thread's dictionary.
1708
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001709- Issue #3004: Minor change to slice.indices(): the start and stop
1710 arguments are now treated identically, making the behaviour easier
1711 to describe and understand. For example, slice(None, -10,
1712 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1713 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1714 10, -1).
1715
Georg Brandl278fc502008-07-19 12:46:12 +00001716- Issue #3219: Calling a function with repeated keyword arguments,
1717 f(a=2, a=23), would not cause a syntax error. This was a regression
1718 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00001719
Georg Brandl278fc502008-07-19 12:46:12 +00001720- Issue #2862: Make int and float freelist management consistent with
1721 other freelists. Changes their CompactFreeList apis into

1728 api functions without holding the GIL, which could lead to a fatal
1729 error when they failed.
1730
Martin v. Löwisaabf4042008-08-02 07:20:25 +00001731- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001756- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
1757 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001758 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00001759 content-length. The problem had been corrected in the 2.4 branch, but never
1760 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00001775- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

2163
Brett Cannonb61d8012008-05-11 23:39:04 +00002164- ``Lib/lib-old`` is now added to sys.path.
2165
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002166- On MacOS X it is now possible to install the framework in 64-bit
2167 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00002168 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00002169
2170 This is controlled by the configure argument ``--with-universal-archs``:
2171
2172 - ``--with-universal-archs=all``: install 4-way universal
2173
2174 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
2175
2176 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
2177
2178 This option should be used in combination with ``--enable-universalsdk=``.
2179
2180 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 +00002189
2190- The PyString functions have been renamed to PyBytes. A batch of
2191 defines were added so that the linker still sees the original
2192 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002230- Issue #1631171: Re-implement the 'warnings' module in C (the
2231 original Python code has been kept as backup). This will allow for
2232 using the 'warning's machinery in such places as the parser where
2233 use of pure Python code is not possible. Both the ``showarning()``
2234 and ``formatwarning()`` gain an optional 'line' argument which is
2235 not called by default for backwards-compatibility reasons. Setting
2236 ``warnings.showwarning()`` to an implementation that lacks support
2237 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00002262- The getpass module has been improved on Unix. It now uses /dev/tty
2263 by default and uses stderr instead of stdout. A GetPassWarning is
2264 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002279- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00002280 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00002300- Issue #2550: The approach used by client/server code for obtaining
2301 ports to listen on in network-oriented tests has been refined in an
2302 effort to facilitate running multiple instances of the entire
2303 regression test suite in parallel without issue.
2304 test_support.bind_port() has been fixed such that it will always
2305 return a unique port -- which wasn't always the case with the
2306 previous implementation, especially if socket options had been set
2307 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2308 new implementation of bind_port() will actually raise an exception
2309 if it is passed an AF_INET/SOCK_STREAM socket with either the
2310 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2311 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2312 the socket it's been passed. This currently only applies to
2313 Windows. This option prevents any other sockets from binding to the
2314 host/port we've bound to, thus removing the possibility of the
2315 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2316 when a second SOCK_STREAM socket binds and accepts to a host/port
2317 that's already been bound by another socket. The optional preferred
2318 port parameter to bind_port() has been removed. Under no
2319 circumstances should tests be hard coding ports!
2320
2321 test_support.find_unused_port() has also been introduced, which will
2322 pass a temporary socket object to bind_port() in order to obtain an
2323 unused port. The temporary socket object is then closed and
2324 deleted, and the port is returned. This method should only be used
2325 for obtaining an unused port in order to pass to an external program
2326 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2327 a parameter to a server-oriented class that doesn't give you direct
2328 access to the underlying socket used.
2329
2330 Finally, test_support.HOST has been introduced, which should be used
2331 for the host argument of any relevant socket calls (i.e. bind and
2332 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002333
2334 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002335 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002336 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2337 test_asynchat and test_socket_ssl.
2338
Georg Brandl3ee81df2008-05-17 18:14:43 +00002339 It is now possible for multiple instances of the regression test
2340 suite to run in parallel without issue.

2606Core and builtins
2607-----------------
2608
Fred Drakea8ee94b2008-03-01 02:45:07 +00002609- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002610 644. The mode is now inherited from the py file.

2613
2614- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002615
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002616- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002617 issue 215555 for a discussion.
2618
Eric Smitha73fbe72008-02-23 03:09:44 +00002619- Added the future_builtins module, which contains hex() and oct().
2620 These are the PEP 3127 version of these functions, designed to be
2621 compatible with the hex() and oct() builtins from Python 3.0. They
2622 differ slightly in their output formats from the existing, unchanged
2623 Python 2.6 builtins. The expected usage of the future_builtins
2624 module is:
2625 from future_builtins import hex, oct
2626
Eric Smith7ef40bf2008-02-20 23:34:22 +00002627- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2628 exponents for exponents with absolute value < 100. Follows C99
2629 standard. This is a change on Windows, which would use 3 digits.
2630 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2631 so that any alterations it does to the resulting string will be
2632 available in stringlib/formatter.h (for float.__format__).
2633
Eric Smith5a3c1352008-02-19 13:21:56 +00002634- Implemented PEP 3101, Advanced String Formatting. This adds a new
2635 builtin format(); a format() method for str and unicode; a
2636 __format__() method to object, str, unicode, int, long, float, and
2637 datetime; the class string.Formatter; and the C API
2638 PyObject_Format().
2639
Georg Brandl3ee81df2008-05-17 18:14:43 +00002640- Fixed several potential crashes, all caused by specially crafted
2641 __del__ methods exploiting objects in temporarily inconsistent
2642 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002643
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002644- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002645 prevent a possible crash: an Abstract Base Class would try to access
2646 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002651- Clear all free lists during a gc.collect() of the highest generation
2652 in order to allow pymalloc to free more arenas. Python may give back
2653 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002654
Georg Brandl3ee81df2008-05-17 18:14:43 +00002655- Issue #2045: Fix an infinite recursion triggered when printing a
2656 subclass of collections.defaultdict, if its default_factory is set
2657 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002658
Christian Heimesf75dbef2008-02-08 00:11:31 +00002659- Fixed a minor memory leak in dictobject.c. The content of the free
2660 list was not freed on interpreter shutdown.
2661
Georg Brandl3ee81df2008-05-17 18:14:43 +00002662- Limit free list of method and builtin function objects to 256
2663 entries each.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002665- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2666 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002667 to compact the internal free lists of pre-allocted ints and floats.
2668
Georg Brandl3ee81df2008-05-17 18:14:43 +00002669- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2670 calls. Python expected the return type int but the fork familie
2671 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002672
Georg Brandl3ee81df2008-05-17 18:14:43 +00002673- Issue #1678380: Fix a bug that identifies 0j and -0j when they

2680 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002681
Georg Brandl3ee81df2008-05-17 18:14:43 +00002682- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2683 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002684
Georg Brandl3ee81df2008-05-17 18:14:43 +00002685- Patch #1473257: generator objects gain a gi_code attribute. This is
2686 the same object as the func_code attribute of the function that
2687 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002688
Georg Brandl3ee81df2008-05-17 18:14:43 +00002689- Issue #1920: "while 0" statements were completely removed by the
2690 compiler, even in the presence of an "else" clause, which is
2691 supposed to be run when the condition is false. Now the compiler
2692 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002693
Guido van Rossumeead05f2008-01-24 18:21:02 +00002694- A few crashers fixed: weakref_in_del.py (issue #1377858);
2695 loosing_dict_ref.py (issue #1303614, test67.py);
2696 borrowed_ref_[34].py (not in tracker).
2697
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002698- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002699 suppressed while an extension is loaded by calling SetErrorMode in
2700 dynload_win.c. The error is still reported properly.
2701
Georg Brandl3ee81df2008-05-17 18:14:43 +00002702- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002703 several extension methods and modules do not work without unicode
2704 support.
2705
Georg Brandl26543b12008-01-21 18:36:51 +00002706- Issue #1882: when compiling code from a string, encoding cookies in the
2707 second line of code were not always recognized correctly.
2708
Georg Brandl14404b62008-01-19 19:27:05 +00002709- Issue #1679: "0x" was taken as a valid integer literal.
2710
Georg Brandl6caad7d2008-01-26 14:19:22 +00002711- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002712 added.
2713
Christian Heimesc94e2b52008-01-14 04:13:37 +00002714- sys.float_info / PyFloat_GetInfo: The floating point information
2715 object was converted from a dict to a specialized structseq object.
2716
Georg Brandl3ee81df2008-05-17 18:14:43 +00002717- Patch #1816: Added sys.flags structseq. It exposes the status of
2718 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002719
Georg Brandl3ee81df2008-05-17 18:14:43 +00002720- Objects/structseq.c: Implemented new structseq representation. The
2721 patch makes structseqs (e.g. the return value of os.stat) more
2722 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002723
Georg Brandl3ee81df2008-05-17 18:14:43 +00002724- Patch #1700288: added a type attribute cache that caches method
2725 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00002726
Neal Norwitz3fc15b82008-01-10 05:42:58 +00002727- Bug #1776: __import__() no longer accepts filenames on any platform.
2728 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00002729
Georg Brandlaed6c662008-01-07 17:25:53 +00002730- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
2731
Georg Brandl3ee81df2008-05-17 18:14:43 +00002732- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
2733 envvar and sys.dont_write_bytecode attribute. All these can be set
2734 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002735
Georg Brandl3ee81df2008-05-17 18:14:43 +00002736- Improve some exception messages when Windows fails to load an
2737 extension module. Now we get for example '%1 is not a valid Win32
2738 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002739
Georg Brandl3ee81df2008-05-17 18:14:43 +00002740- Bug #1481296: Fixed long(float('nan')) != 0L.
Christian Heimes8267d1d2008-01-04 00:37:34 +00002741
Georg Brandl3ee81df2008-05-17 18:14:43 +00002742- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
2743 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00002744
Christian Heimes0a8143f2007-12-18 23:22:54 +00002745- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002746 and INF. float("nan"), float("inf") and float("-inf") now work on
2747 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002748
Georg Brandl3ee81df2008-05-17 18:14:43 +00002749- Compiler now generates simpler and faster code for dictionary
2750 literals. The oparg for BUILD_MAP now indicates an estimated
2751 dictionary size. There is a new opcode, STORE_MAP, for adding
2752 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00002753
Georg Brandl3ee81df2008-05-17 18:14:43 +00002754- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00002755
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756- Issue #1620: New property decorator syntax was modifying the
2757 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00002758
Georg Brandl3ee81df2008-05-17 18:14:43 +00002759- Issue #1538: Avoid copying string in split/rsplit if the split char
2760 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00002761
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00002762- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00002763 SystemError.
2764
Nick Coghlanef01d822007-12-03 12:55:17 +00002765- PEP 366: Allow explicit relative imports when executing modules
2766 inside packages with the -m switch via a new module level
2767 __package__ attribute.
2768
Georg Brandl3ee81df2008-05-17 18:14:43 +00002769- Issue #1402: Fix a crash on exit, when another thread is still
2770 running, and if the deallocation of its frames somehow calls the
2771 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00002772

2774
Vinay Sajip2bdc48c2008-01-21 18:16:05 +00002775- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00002776 attribute of an empty cell object.
2777
Georg Brandl3ee81df2008-05-17 18:14:43 +00002778- Issue #1460: The utf-7 incremental decoder did not accept truncated
2779 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00002780
Georg Brandl3ee81df2008-05-17 18:14:43 +00002781- Patch #1739468: Directories and zipfiles containing a __main__.py
2782 file can now be directly executed by passing their name to the
2783 interpreter. The directory/zipfile is automatically inserted as the
2784 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00002785
Georg Brandl3ee81df2008-05-17 18:14:43 +00002786- Issue #1265: Fix a problem with sys.settrace, if the tracing
2787 function uses a generator expression when at the same time the
2788 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00002789
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00002790- sets and frozensets now have an isdisjoint() method.
2791
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00002792- optimize the performance of builtin.sum().
2793
Neal Norwitz44f326e2007-10-05 05:29:17 +00002794- Fix warnings found by the new version of the Coverity checker.
2795
Georg Brandl3ee81df2008-05-17 18:14:43 +00002796- The enumerate() builtin function is no longer bounded to sequences
2797 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2798 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002799
Georg Brandl3ee81df2008-05-17 18:14:43 +00002800- Issue #1686386: Tuple's tp_repr did not take into account the
2801 possibility of having a self-referential tuple, which is possible
2802 from C code. Nor did object's tp_str consider that a type's tp_str
2803 could do something that could lead to an inifinite recursion.
2804 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2805 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002806
Georg Brandl3ee81df2008-05-17 18:14:43 +00002807- Issue #1164: It was possible to trigger deadlock when using the
2808 'print' statement to write to a file since the GIL was not released
2809 as needed. Now PyObject_Print() does the right thing along with
2810 various tp_print implementations of the built-in types and those in
2811 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00002812
Georg Brandl3ee81df2008-05-17 18:14:43 +00002813- Issue #1147: Exceptions were directly allowing string exceptions in
2814 their throw() method even though string exceptions no longer
2815 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00002816
Georg Brandl3ee81df2008-05-17 18:14:43 +00002817- Issue #1096: Prevent a segfault from getting the repr of a very
2818 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00002819
Brett Cannon1e534b52007-09-07 04:18:30 +00002820- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002821 PyObject_Call() never calling back out to Python code to trigger
2822 recursion depth updates/checks. Required the creation of a static
2823 RuntimeError instance in case normalizing an exception put the
2824 recursion check value past its limit. Fixes crashers
2825 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00002826
Georg Brandl3ee81df2008-05-17 18:14:43 +00002827- Patch #1031213: Decode source line in SyntaxErrors back to its
2828 original source encoding.
Martin v. Löwisa5136192007-09-04 14:19:28 +00002829
Georg Brandl7c3b50d2007-07-12 08:38:00 +00002830- Patch #1673759: add a missing overflow check when formatting floats
2831 with %G.
2832
Georg Brandl3ee81df2008-05-17 18:14:43 +00002833- Prevent expandtabs() on string and unicode objects from causing a
2834 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00002835

Georg Brandl3ee81df2008-05-17 18:14:43 +00002838- Issue #1722485: remove docstrings again when running with -OO.
Georg Brandla5ea6892007-06-01 11:33:33 +00002839
Neal Norwitz0ac60192007-05-27 04:08:54 +00002840- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002841 __*__ attributes. (Some already existed, e.g., __doc__ and
2842 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00002843
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00002844- Add -3 option to the interpreter to warn about features that are
2845 deprecated and will be changed/removed in Python 3.0.
2846
Georg Brandl2134e752007-05-21 20:34:16 +00002847- Patch #1686487: you can now pass any mapping after '**' in function
2848 calls.
2849
Collin Winter62903052007-05-18 23:11:24 +00002850- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002851 "except E as target:". This is to provide forwards compatibility
2852 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00002853
Brett Cannon229cee22007-05-05 01:34:02 +00002854- Deprecate BaseException.message as per PEP 352.
2855
Georg Brandl3ee81df2008-05-17 18:14:43 +00002856- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00002857 inherited from a builtin base.
2858
Vinay Sajip8549ce32007-05-06 17:53:37 +00002859- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002860 setting a plain string, ie don't expand to single letter identifiers.
2861
Raymond Hettinger13936692007-04-11 18:40:58 +00002862- Request #1191699: Slices can now be pickled.
2863
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002864- Request #1193128: str.translate() now allows a None argument for
2865 translations that only remove characters without re-mapping the
2866 remaining characters.
2867
Georg Brandl5cb76c12007-03-21 09:00:39 +00002868- Patch #1682205: a TypeError while unpacking an iterable is no longer
2869 masked by a generic one with the message "unpack non-sequence".
2870
Neal Norwitzaa754b72007-03-21 06:39:48 +00002871- Remove unused file Python/fmod.c.
2872
Guido van Rossum143b5642007-03-23 04:58:42 +00002873- Bug #1683368: The object.__init__() and object.__new__() methods are
2874 now stricter in rejecting excess arguments. The only time when
2875 either allows excess arguments is when it is not overridden and the
2876 other one is. For backwards compatibility, when both are
2877 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002878 warning later). Also, type.__init__() insists on the same signature
2879 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002880
Georg Brandl3ee81df2008-05-17 18:14:43 +00002881- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2882 object to complex using its __complex__() method before falling back
2883 to the __float__() method. Therefore, the functions in the cmath
2884 module now can operate on objects that define a __complex__()
2885 method.
Georg Brandl2b869942007-03-17 16:08:45 +00002886
Georg Brandl3ee81df2008-05-17 18:14:43 +00002887- Patch #1623563: allow __class__ assignment for classes with
2888 __slots__. The old and the new class are still required to have the
2889 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00002890
Georg Brandl3ee81df2008-05-17 18:14:43 +00002891- Patch #1642547: Fix an error/crash when encountering syntax errors
2892 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002894- Patch #1462488: Python no longer segfaults when
2895 ``object.__reduce_ex__()`` is called with an object that is faking
2896 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00002897
Georg Brandl3ee81df2008-05-17 18:14:43 +00002898- Patch #1680015: Don't modify __slots__ tuple if it contains an
2899 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00002901- Patch #1444529: the builtin compile() now accepts keyword arguments.
2902
Georg Brandl7b9c5552007-03-12 14:30:05 +00002903- Bug #1678647: write a newline after printing an exception in any
2904 case, even when converting the value to a string failed.
2905
Georg Brandl871f1bc2007-03-12 13:17:36 +00002906- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002907 its argument, if it exists. If not, it will work like before. This
2908 allows customizing the output of dir() in the presence of a
2909 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00002910
Collin Winter276887b2007-03-12 16:11:39 +00002911- Patch #922167: Python no longer segfaults when faced with infinitely
2912 self-recursive reload() calls (as reported by bug #742342).
2913
Georg Brandl3ee81df2008-05-17 18:14:43 +00002914- Patch #1675981: remove unreachable code from ``type.__new__()``
2915 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00002916
Georg Brandl3ee81df2008-05-17 18:14:43 +00002917- Patch #1491866: change the complex() constructor to allow
2918 parthensized forms. This means complex(repr(x)) now works instead of
2919 raising a ValueError.

3430 ".cpp" too.
3431
Facundo Batistad918a652007-04-24 13:54:38 +00003432- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003433 the client's request was successfully received, understood, and
3434 accepted. Now in these cases no error is raised in urllib (issue
3435 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00003436

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00003443- Added a timeout parameter to the constructor of other protocols
3444 (telnetlib, ftplib, smtplib and poplib). This is second part of the
3445 work started with create_connection() and timeout in httplib, and
3446 closes patch #723312.
3447
Vinay Sajip8549ce32007-05-06 17:53:37 +00003448- Patch #1676823: Added create_connection() to socket.py, which may be
3449 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00003450 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00003451
Martin v. Löwis0af33882007-03-23 13:27:15 +00003452- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003459- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
3460 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00003461 directories.
3462

3464 GNOME or KDE browser, depending on whether there is a session of one
3465 of those present. Also, it tries the Windows default browser before
3466 trying Mozilla variants.

3472
Georg Brandlf66b6032007-03-14 08:27:52 +00003473- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00003474 AttributeError instead of an IOError when the server's response
3475 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00003476
Georg Brandl3ee81df2008-05-17 18:14:43 +00003477- Patch #957650: "%var%" environment variable references are now
3478 properly expanded in ntpath.expandvars(), also "~user" home
3479 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00003480
Georg Brandl3ee81df2008-05-17 18:14:43 +00003481- Patch #1429539: pdb now correctly initializes the __main__ module
3482 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00003483 correctly now.
3484
Georg Brandlbad6f192007-03-13 21:32:56 +00003485- The nonobvious commands.getstatus() function is now deprecated.

3491
Georg Brandl3ee81df2008-05-17 18:14:43 +00003492- Patch #1530482: add pydoc.render_doc() which returns the
3493 documentation for a thing instead of paging it to stdout, which
3494 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00003495
Georg Brandl3ee81df2008-05-17 18:14:43 +00003496- Patch #1533909: the timeit module now accepts callables in addition

3502 parameter which can be set to False to prevent the default
3503 delete-on-close behavior.

Georg Brandl9e6b4702007-03-13 18:15:41 +00003505- Patch #1581073: add a flag to textwrap that prevents the dropping of
3506 whitespace while wrapping.
3507
Georg Brandl92a6bae2007-03-13 17:43:32 +00003508- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003509 are set for invalid interpolation sequences that would lead to
3510 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00003511

3524
Georg Brandl94fe3f52007-03-13 09:32:11 +00003525- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00003526 field names in its exception message if you try to write a record
3527 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00003545

3553 returned string up to the first NUL character.
3554

3564
Georg Brandl3ee81df2008-05-17 18:14:43 +00003565- unittest now verifies more of its assumptions. In particular,
3566 TestCase and TestSuite subclasses (not instances) are no longer
3567 accepted in TestSuite.addTest(). This should cause no
3568 incompatibility since it never made sense with ordinary subclasses
3569 -- the failure just occurred later, with a more cumbersome
3570 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00003571

3579 given a unicode argument and os.listdir() returns unicode filenames.
3580
Georg Brandl3ee81df2008-05-17 18:14:43 +00003581- Patch #1673619: setup.py identifies extension modules it doesn't

3583 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003959 time so that opening a database previously created with the DB_DUP
3960 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3961 opens. Specifically: dictionary assignment to a DB object will
3962 replace all values for a given key when the database allows
3963 duplicate values. DB users should use DB.put(k, v) when they want
3964 to store duplicates; not DB[k] = v.

3971 characters with ASCII value less than 32. Also, it correctly quotes
3972 dots only if they occur on a single line, as opposed to the previous
3973 behavior of quoting dots if they are the second character of any
3974 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00003975
