1011What's New in Python 2.6.1
1012==========================
1013
1014*Release date: 04-Dec-2008*
1015
1016Core and Builtins
1017-----------------
1018
1019- Issue #3996: On Windows, the PyOS_CheckStack function would cause the
1020 interpreter to abort ("Fatal Python error: Could not reset the stack!")
1021 instead of throwing a MemoryError.
1022
1023- Issue #4367: Python would segfault during compiling when the unicodedata
1024 module couldn't be imported and \N escapes were present.
1025
1026- Issue #4348: Some bytearray methods returned that didn't cause any change to
1027 the bytearray, returned the same bytearray instead of a copy.
1028
1029- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.
1030
1031- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.
1032
1033- Issue #4048: The parser module now correctly validates relative imports.
1034
1035- Issue #4225: ``from __future__ import unicode_literals`` didn't work in an
1036 exec statement.
1037
1038- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
1039 method does not return iterators for the 4th and 5th items.
1040
1041- Issue #4209: Enabling unicode_literals and the print_function in the same
1042 __future__ import didn't work.
1043
1044- On windows, os.chdir given unicode was not working if GetCurrentDirectoryW
1045 returned a path longer than MAX_PATH. (But It's doubtful this code path is
1046 really executed because I cannot move to such directory on win2k)
1047
1048- Issue #4069: When set.remove(element) is used with a set element, the element
1049 is temporarily replaced with an equivalent frozenset. But the eventual
1050 KeyError would always report the empty frozenset([]) as the missing key. Now
1051 it correctly refers to the initial element.
1052
1053- Fixed C99 style comments in several files. Python is now C89 compatible
1054 again.

1202
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00001203- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
1204 PyString_FromFormat or PyErr_Format to display size_t values. The macro
1205 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
1206 ``printf`` function, whereas PyString_FromFormat has an independent
1207 implementation and uses "%zd" on all platforms for size_t values.
1208 This makes a difference on win64, where ``printf`` needs "%Id" to display
1209 64bit values.

1232 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
1233 type object.

1301 path to the Python binary.
1302
Brett Cannon1eaf0742008-09-02 01:25:16 +00001303- Issue 3602: Moved test.test_support.catch_warning() to
1304 warnings.catch_warnings() along with some API cleanup. Expanding the tests
1305 for catch_warnings() also led to an improvement in the raising of a
1306 DeprecationWarning related to warnings.warn_explicit().
1307
Benjamin Peterson973e6c22008-09-01 23:12:58 +00001308- The deprecation warnings for the old camelCase threading API were removed.
1309

1311
Christian Heimesa27a62e2008-08-22 19:55:54 +00001312- Silenced a trivial compiler warning in the sqlite module.
1313
Christian Heimes1cc69632008-08-22 20:10:27 +00001314- Fixed two format strings in the _collections module.
1315
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00001316- Issue #3703: _fileio.FileIO gave unhelpful error message when trying to open a

Benjamin Peterson37346b22008-08-23 20:27:43 +00001325Extension Modules
1326-----------------
1327
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00001328- Issue #2975: When compiling several extension modules with Visual Studio 2008
1329 from the same python interpreter, some environment variables would grow
1330 without limit.
1331
Benjamin Peterson37346b22008-08-23 20:27:43 +00001332- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
1333 exploitation of poor argument checking.
1334
Gerhard Häringef2276b2008-09-12 13:54:06 +00001335- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".

Gerhard Häring6e1afcf2008-09-12 18:58:57 +00001337- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
1338 remaining ones have "pysqlite_" prefix.
1339
Gerhard Häringe6872eb2008-09-12 22:33:22 +00001340- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

1348 wrapper for warnings.catch_warnings() that makes it easier to check
1349 that expected warning messages are being reported.
1350
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00001351- Issue #3796: Some tests functions were not enabled in test_float.

1359
Martin v. Löwis3f5fda82008-09-08 13:50:10 +00001360- Issue #2271: Set SecureCustomProperties so that installation will properly

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001369What's New in Python 2.6 beta 3?
1370================================
1371
Barry Warsaw07a4a382008-08-21 01:15:08 +00001372*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001373
1374Core and Builtins
1375-----------------
1376
Guido van Rossumf8402962008-08-20 15:01:50 +00001377- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
1378 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
1379 extensions do not automatically benefit from the class attribute
1380 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
1381 to their tp_flags field if they care. This is a backwards
1382 compatibility feature; in 3.0, all types will use the cache by
1383 default.
1384
Benjamin Petersonf647dc12008-08-20 01:27:30 +00001385- Keyword arguments can now follow starred arguments. (``f(a, *args,
1386 keyword=23)`` is now valid syntax.)
1387
Thomas Heller0ad5ae02008-08-19 19:25:04 +00001388- ctypes function pointers that are COM methods have a boolean True
1389 value again.
1390
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00001391- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
1392 by denying s# to parse objects that have a releasebuffer procedure,
1393 and introducing s*.
1394
Georg Brandl1e13ea92008-08-11 09:07:59 +00001395- Issue #3537: Fix an assertion failure when an empty but presized dict
1396 object was stored in the freelist.
1397
Mark Dickinsonb6467572008-08-04 21:30:09 +00001398- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
1399 ValueError consistently across platforms.
1400
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00001401- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
1402 (64bit Unix, for example), unichr() would truncate its argument and return
1403 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
1404
Neal Norwitze7d8be82008-07-31 17:17:14 +00001405- Apply security patches from Apple.
1406
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00001407- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
1408 PyErr_ExceptionMatches returns 0 when an exception occurs there.
1409
Antoine Pitrou92f82162008-07-25 22:22:08 +00001410- Issue #1819: function calls with several named parameters are now on
1411 average 35% faster (as measured by pybench).
1412
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00001413- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
1414 the python debugger steps into a class statement: the free variables (local
1415 variables defined in an outer scope) would be deleted from the outer scope.
1416
Gregory P. Smith0470bab2008-07-22 04:46:32 +00001417- Issue #2620: Overflow checking when allocating or reallocating memory
1418 was not always being done properly in some python types and extension
1419 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
1420 all been updated to perform better checks and places in the code that
1421 would previously leak memory on the error path when such an allocation
1422 failed have been fixed.
1423
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00001424Library
1425-------
1426
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00001427- Issue #3612: Added some missing basic types in ctypes.wintypes.
1428
Benjamin Petersone977ad42008-08-20 01:42:01 +00001429- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
1430 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
1431
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00001432- Issue #2234: distutils failed for some versions of the cygwin compiler. The
1433 version reported by these tools does not necessarily follow the python
1434 version numbering scheme, so the module is less strict when parsing it.
1435
Nick Coghlanf70385a2008-08-18 12:42:46 +00001436- Issue #2235: Added Py3k warnings for types which will become unhashable
1437 under the stricter __hash__ inheritance rules in 3.0. Several types
1438 which did not meet the rules for hash invariants and were already
1439 unhashable in 3.0 have now been explicitly flagged as unhashable in
1440 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
1441 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
1442
Brett Cannon88f801d2008-08-18 00:46:22 +00001443- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
1444 imported into the module but exposed as part of the module's API.
1445
Brett Cannon7b96f072008-08-18 00:41:11 +00001446- Remove an unneeded import of abc.ABCMeta from 'inspect'.
1447
Brett Cannon46225e72008-08-18 00:36:52 +00001448- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00001450- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
1451
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00001452- Issue #3575: Incremental decoder's decode function now takes bytearray
1453 by using 's*' instead of 't#'.
1454
Jesus Cea585ad8a2009-07-02 15:37:21 +00001455- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00001456 fails unicode conversion on 2nd parameter. (windows only)
1457
Facundo Batista94f243a2008-08-17 03:38:39 +00001458- Issue 2464. urllib2 now supports a malformation in the URL received
1459 in a redirect.
1460
Brett Cannonabe423e2008-08-16 21:47:07 +00001461- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00001462 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00001463
Facundo Batistaeb90b782008-08-16 14:44:07 +00001464- Issue #2776: fixed small issue when handling an URL with double slash
1465 after a 302 response in the case of not going through a proxy.
1466
Antoine Pitroub90a8be2008-08-15 21:03:21 +00001467- Issue #2676: in the email package, content-type parsing was hanging on
1468 pathological input because of quadratic or exponential behaviour of a
1469 regular expression.
1470
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00001471- Issue #3476: binary buffered reading through the new "io" library is now
1472 thread-safe.
1473
Brett Cannonbf3157b2008-08-14 05:00:03 +00001474- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
1475 since mimetools itself is deprecated. Because modules are cached, all
1476 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
1477
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00001478- Issue #3134: shutil referenced undefined WindowsError symbol.
1479
Robert Schuppenies14646332008-08-10 11:01:53 +00001480- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
1481 menu entries were not deleted.
1482
Brett Cannon83e81842008-08-09 23:30:55 +00001483- Copied the implementation of reduce() to _functools.reduce() to have a
1484 version that did not raise a DeprecationWarning under -3.
1485
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00001486- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
1487 a MemoryError rather than silently stop the iteration.
1488
Guido van Rossum59ce9012008-08-09 14:55:34 +00001489- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
1490 to _sre.compile() will now be rejected. This should not affect anybody
1491 since the re.compile() function never generates invalid re-bytecode.
1492
Skip Montanaroa032bf42008-08-08 22:52:51 +00001493- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
1494 upon first access it can be automatically initialized from the csv file if
1495 it wasn't initialized during instantiation.
1496
Brett Cannon3aa2a492008-08-06 22:28:09 +00001497- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
1498 the reload() built-in has been removed.
1499
Brett Cannon7e30b672008-08-04 21:52:25 +00001500- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00001501 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00001512 asking for a specific length. This problem only affected files opened
1513 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00001514

1537
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +00001538- Issue #3394: zipfile.writestr sets external attributes when passed a
1539 file name rather than a ZipInfo instance, so files are extracted with
1540 mode 0600 rather than 000 under Unix.
1541
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00001542- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
1543 argument in python 2.5, this broke code that subclassed Popen to include its
1544 own poll method. Fixed my moving _deadstate to an _internal_poll method.

1558 coverage of the lookup process for special methods. The disclaimers
1559 regarding lack of coverage of new-style classes have also been
1560 removed, since the coverage is now fairly reasonable.

1569-----------------
1570
Georg Brandl3e483f62008-07-16 22:57:41 +00001571- Issue #3156: Fix inconsistent behavior of the bytearray type: all
1572 its methods now allow for items objects that can be converted to
1573 an integer using operator.index().
1574
Mark Dickinson64b7e502008-07-16 09:40:03 +00001575- Issue #3360: Fix incorrect parsing of '020000000000.0', which
1576 produced a ValueError instead of giving the correct float.
1577
Eric Smitha5fa5a22008-07-16 00:11:49 +00001578- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
1579 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
1580
Mark Dickinson7103aa42008-07-15 19:08:33 +00001581- Issue #3008: the float type has a new instance method 'float.hex'
1582 and a new class method 'float.fromhex' to convert floating-point
1583 numbers to and from hexadecimal strings, respectively.
1584
Nick Coghlan6d6bd442008-07-15 15:40:22 +00001585- Issue #2235: __hash__ is once again inherited by default. To allow
1586 collections.Hashable to remain meaningful in the presence of the
1587 default hash implementation (object.__hash__), it is now possible
1588 to explicit block inheritance of hash by setting __hash__=None at
1589 the Python level, or tp_hash=PyObject_HashNotImplemented at the C

Nick Coghlanb028f502008-07-13 14:52:36 +00001592- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
1593 the parent module cannot be found while performing an absolute import.
1594 This means that an incorrectly defined __package__ attribute will
1595 now only prevent relative imports in that module rather than causing
1596 all imports from that module to fail.

Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00001610- Issue #3004: Minor change to slice.indices(): the start and stop
1611 arguments are now treated identically, making the behaviour easier
1612 to describe and understand. For example, slice(None, -10,
1613 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
1614 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
1615 10, -1).

1658 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00001659 wrong because the actual transmitted size could differ from the

Georg Brandl3ee81df2008-05-17 18:14:43 +00002131- Issue #1631171: Re-implement the 'warnings' module in C (the
2132 original Python code has been kept as backup). This will allow for
2133 using the 'warning's machinery in such places as the parser where
2134 use of pure Python code is not possible. Both the ``showarning()``
2135 and ``formatwarning()`` gain an optional 'line' argument which is
2136 not called by default for backwards-compatibility reasons. Setting
2137 ``warnings.showwarning()`` to an implementation that lacks support
2138 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002201- Issue #2550: The approach used by client/server code for obtaining
2202 ports to listen on in network-oriented tests has been refined in an
2203 effort to facilitate running multiple instances of the entire
2204 regression test suite in parallel without issue.
2205 test_support.bind_port() has been fixed such that it will always
2206 return a unique port -- which wasn't always the case with the
2207 previous implementation, especially if socket options had been set
2208 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
2209 new implementation of bind_port() will actually raise an exception
2210 if it is passed an AF_INET/SOCK_STREAM socket with either the
2211 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
2212 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
2213 the socket it's been passed. This currently only applies to
2214 Windows. This option prevents any other sockets from binding to the
2215 host/port we've bound to, thus removing the possibility of the
2216 'non-deterministic' behaviour, as Microsoft puts it, that occurs
2217 when a second SOCK_STREAM socket binds and accepts to a host/port
2218 that's already been bound by another socket. The optional preferred
2219 port parameter to bind_port() has been removed. Under no
2220 circumstances should tests be hard coding ports!
2221
2222 test_support.find_unused_port() has also been introduced, which will
2223 pass a temporary socket object to bind_port() in order to obtain an
2224 unused port. The temporary socket object is then closed and
2225 deleted, and the port is returned. This method should only be used
2226 for obtaining an unused port in order to pass to an external program
2227 (i.e. the -accept [port] argument to openssl's s_server mode) or as
2228 a parameter to a server-oriented class that doesn't give you direct
2229 access to the underlying socket used.
2230
2231 Finally, test_support.HOST has been introduced, which should be used
2232 for the host argument of any relevant socket calls (i.e. bind and
2233 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00002234
2235 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00002236 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00002237 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
2238 test_asynchat and test_socket_ssl.
2239
Georg Brandl3ee81df2008-05-17 18:14:43 +00002240 It is now possible for multiple instances of the regression test
2241 suite to run in parallel without issue.

2507Core and builtins
2508-----------------
2509
Fred Drakea8ee94b2008-03-01 02:45:07 +00002510- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00002511 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00002512
Georg Brandlad61bc82008-02-23 15:11:18 +00002513- Issue #2067: file.__exit__() now calls subclasses' close() method.
2514
2515- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00002516
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002517- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00002518 issue 215555 for a discussion.
2519
Eric Smitha73fbe72008-02-23 03:09:44 +00002520- Added the future_builtins module, which contains hex() and oct().
2521 These are the PEP 3127 version of these functions, designed to be
2522 compatible with the hex() and oct() builtins from Python 3.0. They
2523 differ slightly in their output formats from the existing, unchanged
2524 Python 2.6 builtins. The expected usage of the future_builtins
2525 module is:
2526 from future_builtins import hex, oct
2527
Eric Smith7ef40bf2008-02-20 23:34:22 +00002528- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
2529 exponents for exponents with absolute value < 100. Follows C99
2530 standard. This is a change on Windows, which would use 3 digits.
2531 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
2532 so that any alterations it does to the resulting string will be
2533 available in stringlib/formatter.h (for float.__format__).
2534
Eric Smith5a3c1352008-02-19 13:21:56 +00002535- Implemented PEP 3101, Advanced String Formatting. This adds a new
2536 builtin format(); a format() method for str and unicode; a
2537 __format__() method to object, str, unicode, int, long, float, and
2538 datetime; the class string.Formatter; and the C API
2539 PyObject_Format().
2540
Georg Brandl3ee81df2008-05-17 18:14:43 +00002541- Fixed several potential crashes, all caused by specially crafted
2542 __del__ methods exploiting objects in temporarily inconsistent
2543 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00002544
Vinay Sajipb7edfc42008-04-02 21:10:23 +00002545- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00002546 prevent a possible crash: an Abstract Base Class would try to access
2547 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00002548
Georg Brandl3ee81df2008-05-17 18:14:43 +00002549- Fixed repr() and str() of complex numbers with infinity or nan as
2550 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00002551
Georg Brandl3ee81df2008-05-17 18:14:43 +00002552- Clear all free lists during a gc.collect() of the highest generation
2553 in order to allow pymalloc to free more arenas. Python may give back
2554 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00002555
Georg Brandl3ee81df2008-05-17 18:14:43 +00002556- Issue #2045: Fix an infinite recursion triggered when printing a
2557 subclass of collections.defaultdict, if its default_factory is set
2558 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00002559
Christian Heimesf75dbef2008-02-08 00:11:31 +00002560- Fixed a minor memory leak in dictobject.c. The content of the free
2561 list was not freed on interpreter shutdown.
2562
Georg Brandl3ee81df2008-05-17 18:14:43 +00002563- Limit free list of method and builtin function objects to 256
2564 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00002565
Georg Brandl3ee81df2008-05-17 18:14:43 +00002566- Patch #1953: Added ``sys._compact_freelists()`` and the C API
2567 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00002568 to compact the internal free lists of pre-allocted ints and floats.
2569
Georg Brandl3ee81df2008-05-17 18:14:43 +00002570- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
2571 calls. Python expected the return type int but the fork familie
2572 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00002573
Georg Brandl3ee81df2008-05-17 18:14:43 +00002574- Issue #1678380: Fix a bug that identifies 0j and -0j when they
2575 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00002576
Georg Brandl3ee81df2008-05-17 18:14:43 +00002577- Issue #2025: Add tuple.count() and tuple.index() methods to comply
2578 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00002579
Georg Brandl3ee81df2008-05-17 18:14:43 +00002580- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
2581 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00002582
Georg Brandl3ee81df2008-05-17 18:14:43 +00002583- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
2584 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00002585
Georg Brandl3ee81df2008-05-17 18:14:43 +00002586- Patch #1473257: generator objects gain a gi_code attribute. This is
2587 the same object as the func_code attribute of the function that
2588 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00002589
Georg Brandl3ee81df2008-05-17 18:14:43 +00002590- Issue #1920: "while 0" statements were completely removed by the
2591 compiler, even in the presence of an "else" clause, which is
2592 supposed to be run when the condition is false. Now the compiler
2593 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00002594
Guido van Rossumeead05f2008-01-24 18:21:02 +00002595- A few crashers fixed: weakref_in_del.py (issue #1377858);
2596 loosing_dict_ref.py (issue #1303614, test67.py);
2597 borrowed_ref_[34].py (not in tracker).
2598
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00002599- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00002600 suppressed while an extension is loaded by calling SetErrorMode in
2601 dynload_win.c. The error is still reported properly.
2602
Georg Brandl3ee81df2008-05-17 18:14:43 +00002603- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00002604 several extension methods and modules do not work without unicode
2605 support.
2606
Georg Brandl26543b12008-01-21 18:36:51 +00002607- Issue #1882: when compiling code from a string, encoding cookies in the
2608 second line of code were not always recognized correctly.
2609
Georg Brandl14404b62008-01-19 19:27:05 +00002610- Issue #1679: "0x" was taken as a valid integer literal.
2611
Georg Brandl6caad7d2008-01-26 14:19:22 +00002612- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00002613 added.
2614
Christian Heimesc94e2b52008-01-14 04:13:37 +00002615- sys.float_info / PyFloat_GetInfo: The floating point information
2616 object was converted from a dict to a specialized structseq object.
2617
Georg Brandl3ee81df2008-05-17 18:14:43 +00002618- Patch #1816: Added sys.flags structseq. It exposes the status of
2619 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00002620
Georg Brandl3ee81df2008-05-17 18:14:43 +00002621- Objects/structseq.c: Implemented new structseq representation. The
2622 patch makes structseqs (e.g. the return value of os.stat) more
2623 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00002624
Georg Brandl3ee81df2008-05-17 18:14:43 +00002625- Patch #1700288: added a type attribute cache that caches method
2626 accesses, resulting in speedups in heavily object-oriented code.

2634 envvar and sys.dont_write_bytecode attribute. All these can be set
2635 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00002636
Georg Brandl3ee81df2008-05-17 18:14:43 +00002637- Improve some exception messages when Windows fails to load an
2638 extension module. Now we get for example '%1 is not a valid Win32
2639 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00002640

Christian Heimes0a8143f2007-12-18 23:22:54 +00002646- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00002647 and INF. float("nan"), float("inf") and float("-inf") now work on
2648 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00002649
Georg Brandl3ee81df2008-05-17 18:14:43 +00002650- Compiler now generates simpler and faster code for dictionary
2651 literals. The oparg for BUILD_MAP now indicates an estimated
2652 dictionary size. There is a new opcode, STORE_MAP, for adding
2653 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002682- Patch #1739468: Directories and zipfiles containing a __main__.py
2683 file can now be directly executed by passing their name to the
2684 interpreter. The directory/zipfile is automatically inserted as the
2685 first entry in sys.path.

2696
Georg Brandl3ee81df2008-05-17 18:14:43 +00002697- The enumerate() builtin function is no longer bounded to sequences
2698 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
2699 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00002700
Georg Brandl3ee81df2008-05-17 18:14:43 +00002701- Issue #1686386: Tuple's tp_repr did not take into account the
2702 possibility of having a self-referential tuple, which is possible
2703 from C code. Nor did object's tp_str consider that a type's tp_str
2704 could do something that could lead to an inifinite recursion.
2705 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
2706 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00002707
Georg Brandl3ee81df2008-05-17 18:14:43 +00002708- Issue #1164: It was possible to trigger deadlock when using the
2709 'print' statement to write to a file since the GIL was not released
2710 as needed. Now PyObject_Print() does the right thing along with
2711 various tp_print implementations of the built-in types and those in
2712 the collections module.

Brett Cannon1e534b52007-09-07 04:18:30 +00002721- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00002722 PyObject_Call() never calling back out to Python code to trigger
2723 recursion depth updates/checks. Required the creation of a static
2724 RuntimeError instance in case normalizing an exception put the
2725 recursion check value past its limit. Fixes crashers

Neal Norwitz0ac60192007-05-27 04:08:54 +00002741- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00002742 __*__ attributes. (Some already existed, e.g., __doc__ and
2743 __name__.)

2749 calls.
2750
Collin Winter62903052007-05-18 23:11:24 +00002751- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00002752 "except E as target:". This is to provide forwards compatibility
2753 with Python 3.0.

2759
Vinay Sajip8549ce32007-05-06 17:53:37 +00002760- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00002761 setting a plain string, ie don't expand to single letter identifiers.
2762
Raymond Hettinger13936692007-04-11 18:40:58 +00002763- Request #1191699: Slices can now be pickled.
2764
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00002765- Request #1193128: str.translate() now allows a None argument for

2767 remaining characters.
2768
Georg Brandl5cb76c12007-03-21 09:00:39 +00002769- Patch #1682205: a TypeError while unpacking an iterable is no longer

2773
Guido van Rossum143b5642007-03-23 04:58:42 +00002774- Bug #1683368: The object.__init__() and object.__new__() methods are
2775 now stricter in rejecting excess arguments. The only time when
2776 either allows excess arguments is when it is not overridden and the
2777 other one is. For backwards compatibility, when both are
2778 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00002779 warning later). Also, type.__init__() insists on the same signature
2780 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00002781
Georg Brandl3ee81df2008-05-17 18:14:43 +00002782- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
2783 object to complex using its __complex__() method before falling back
2784 to the __float__() method. Therefore, the functions in the cmath
2785 module now can operate on objects that define a __complex__()
2786 method.

2797 its type.

Georg Brandl7b9c5552007-03-12 14:30:05 +00002804- Bug #1678647: write a newline after printing an exception in any
2805 case, even when converting the value to a string failed.
2806
Georg Brandl871f1bc2007-03-12 13:17:36 +00002807- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00002808 its argument, if it exists. If not, it will work like before. This
2809 allows customizing the output of dir() in the presence of a
2810 __getattr__().

2814
Georg Brandl3ee81df2008-05-17 18:14:43 +00002815- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00002818- Patch #1491866: change the complex() constructor to allow
2819 parthensized forms. This means complex(repr(x)) now works instead of
2820 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00002821
Georg Brandlaa2321b2007-03-07 00:40:28 +00002822- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00002823 makes the filenames the warning module prints much more sensible
2824 when a PYTHONSTARTUP file is used.

Georg Brandl0fca97a2007-03-05 22:28:08 +00002837- Patch #1674228: when assigning a slice (old-style), check for the
2838 sq_ass_slice instead of the sq_slice slot.
2839
Georg Brandl3ee81df2008-05-17 18:14:43 +00002840- When printing an unraisable error, don't print exceptions. before
2841 the name. This duplicates the behavior whening normally printing
2842 exceptions.

2899
Armin Rigo7ccbca92006-10-04 12:17:45 +00002900- A number of places, including integer negation and absolute value,

Georg Brandl3ee81df2008-05-17 18:14:43 +00003393- Patch #1530482: add pydoc.render_doc() which returns the

3408
Georg Brandl92a6bae2007-03-13 17:43:32 +00003409- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00003410 are set for invalid interpolation sequences that would lead to

3467 TestCase and TestSuite subclasses (not instances) are no longer
3468 accepted in TestSuite.addTest(). This should cause no
3469 incompatibility since it never made sense with ordinary subclasses
3470 -- the failure just occurred later, with a more cumbersome
3471 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003752- Issue #829951: In the smtplib module, SMTP.starttls() now complies
3753 with RFC 3207 and forgets any knowledge obtained from the server not
3754 obtained from the TLS negotiation itself. Patch contributed by Bill
3755 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00003756
Georg Brandl3ee81df2008-05-17 18:14:43 +00003757- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00003758 that the SMTP.starttls() caller no longer needs to call ehlo()
3759 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00003760 does not claim to support starttls. Adds the
3761 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

3842 complex, tuple, list, dict, set, and frozenset. Formerly, it would
3843 silently miscode subclasses of those types. Now, it raises a

Raymond Hettinger12e94202007-11-07 01:13:09 +00003845

Georg Brandl3ee81df2008-05-17 18:14:43 +00003860 time so that opening a database previously created with the DB_DUP
3861 or DB_DUPSORT flag set will keep the proper behavior on subsequent
3862 opens. Specifically: dictionary assignment to a DB object will
3863 replace all values for a given key when the database allows
3864 duplicate values. DB users should use DB.put(k, v) when they want
3865 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00003866

3872 characters with ASCII value less than 32. Also, it correctly quotes
3873 dots only if they occur on a single line, as opposed to the previous
3874 behavior of quoting dots if they are the second character of any

Raymond Hettingerdc1d1ba2007-11-07 02:45:46 +00004144- Add a FAST_LOOPS build option that speeds-up looping by trading away
Georg Brandl3ee81df2008-05-17 18:14:43 +00004145 periodic threadstate and signal checking in tight loops. By
4146 default, this option is turned-off. It should only be enabled in
4147 debugged, performance critical applications.

4198-----
4199
Georg Brandl3ee81df2008-05-17 18:14:43 +00004200- Unified naming convention for free lists and their limits. All free
4201 lists in Object/ are named ``free_list``, the counter ``numfree``
4202 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
4203 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00004204
Georg Brandl3ee81df2008-05-17 18:14:43 +00004205- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
4206 to ``PyTuple_SetItem``, it can be used to populate a brand new
4207 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00004208

4219
Georg Brandl3ee81df2008-05-17 18:14:43 +00004220- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
4221 of w# format code incorrectly truncated the length to an int, even
4222 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
4223 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00004224
Georg Brandl3ee81df2008-05-17 18:14:43 +00004225- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,

4245
4246- Make _PyGILState_NoteThreadState() static, it was not used anywhere
4247 outside of pystate.c and should not be necessary.
4248
Georg Brandl3ee81df2008-05-17 18:14:43 +00004249- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
4250 absolute imports. In earlier versions they might have used relative
4251 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00004252
Georg Brandl3ee81df2008-05-17 18:14:43 +00004253- Added case insensitive comparison methods ``PyOS_stricmp(char*,
4254 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00004255
Georg Brandl3ee81df2008-05-17 18:14:43 +00004256- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00004281- Removed the macfs module. It had been deprecated since Python 2.5.
4282 This lead to the deprecation of macostools.touched() as it relied
4283 solely on macfs and was a no-op under OS X.
