Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000172- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
173
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000174- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
175 PyString_FromFormat or PyErr_Format to display size_t values. The macro
176 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
177 ``printf`` function, whereas PyString_FromFormat has an independent
178 implementation and uses "%zd" on all platforms for size_t values.
179 This makes a difference on win64, where ``printf`` needs "%Id" to display
180 64bit values.
181
Benjamin Peterson97179b02008-09-09 20:55:01 +0000182- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

186 object; previously an int would be returned for small values. the __long__
187 method is allowed to return either an int or a long, but the behaviour of
188 float objects should not change to respect backward compatibility.
189
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000190- Issue #3751: str.rpartition would perform a left-partition when called with
191 a unicode argument.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000196 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000197 was correctly parsed but parsing of subsequent arguments failed.
198
Vinay Sajip35e3b032008-09-01 14:33:59 +0000199- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000200 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
201 mechanism. In the process, fix a bug where isinstance() and issubclass(),
202 when given a tuple of classes as second argument, were looking up
203 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
204 type object.
205
Neal Norwitz18aa3882008-08-24 05:04:52 +0000206- Fix crashes on memory allocation failure found with failmalloc.

Christian Heimes7d4c3172008-08-22 19:47:25 +0000214- Silenced another compiler warning about a used but not defined
215 function 'stringlib_contains_obj'.

320 that expected warning messages are being reported.
321
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +0000322- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000340What's New in Python 2.6 beta 3?
341================================
342
Barry Warsaw07a4a382008-08-21 01:15:08 +0000343*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000344
345Core and Builtins
346-----------------
347
Guido van Rossumf8402962008-08-20 15:01:50 +0000348- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
349 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
350 extensions do not automatically benefit from the class attribute
351 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
352 to their tp_flags field if they care. This is a backwards
353 compatibility feature; in 3.0, all types will use the cache by
354 default.
355
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000356- Keyword arguments can now follow starred arguments. (``f(a, *args,
357 keyword=23)`` is now valid syntax.)
358
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000359- ctypes function pointers that are COM methods have a boolean True
360 value again.
361
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000362- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
363 by denying s# to parse objects that have a releasebuffer procedure,
364 and introducing s*.
365
Georg Brandl1e13ea92008-08-11 09:07:59 +0000366- Issue #3537: Fix an assertion failure when an empty but presized dict
367 object was stored in the freelist.
368
Mark Dickinsonb6467572008-08-04 21:30:09 +0000369- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
370 ValueError consistently across platforms.
371
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000372- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
373 (64bit Unix, for example), unichr() would truncate its argument and return
374 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
375
Neal Norwitze7d8be82008-07-31 17:17:14 +0000376- Apply security patches from Apple.
377
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000378- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
379 PyErr_ExceptionMatches returns 0 when an exception occurs there.
380
Antoine Pitrou92f82162008-07-25 22:22:08 +0000381- Issue #1819: function calls with several named parameters are now on
382 average 35% faster (as measured by pybench).
383
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000384- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
385 the python debugger steps into a class statement: the free variables (local
386 variables defined in an outer scope) would be deleted from the outer scope.
387
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000388- Issue #2620: Overflow checking when allocating or reallocating memory
389 was not always being done properly in some python types and extension
390 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
391 all been updated to perform better checks and places in the code that
392 would previously leak memory on the error path when such an allocation
393 failed have been fixed.
394
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000395Library
396-------
397
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000398- Issue #3612: Added some missing basic types in ctypes.wintypes.
399
Benjamin Petersone977ad42008-08-20 01:42:01 +0000400- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
401 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
402
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000403- Issue #2234: distutils failed for some versions of the cygwin compiler. The
404 version reported by these tools does not necessarily follow the python
405 version numbering scheme, so the module is less strict when parsing it.
406
Nick Coghlanf70385a2008-08-18 12:42:46 +0000407- Issue #2235: Added Py3k warnings for types which will become unhashable
408 under the stricter __hash__ inheritance rules in 3.0. Several types
409 which did not meet the rules for hash invariants and were already
410 unhashable in 3.0 have now been explicitly flagged as unhashable in
411 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
412 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
413
Brett Cannon88f801d2008-08-18 00:46:22 +0000414- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
415 imported into the module but exposed as part of the module's API.
416
Brett Cannon7b96f072008-08-18 00:41:11 +0000417- Remove an unneeded import of abc.ABCMeta from 'inspect'.
418
Brett Cannon46225e72008-08-18 00:36:52 +0000419- Remove unneeded imports of 'sys' and 'warnings' from 'io'.
420
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000421- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
422
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000423- Issue #3575: Incremental decoder's decode function now takes bytearray
424 by using 's*' instead of 't#'.
425
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000426- Issue #2222: Fixed reference leak when occured os.rename()
427 fails unicode conversion on 2nd parameter. (windows only)
428
Facundo Batista94f243a2008-08-17 03:38:39 +0000429- Issue 2464. urllib2 now supports a malformation in the URL received
430 in a redirect.
431
Brett Cannonabe423e2008-08-16 21:47:07 +0000432- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000433 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000434
Facundo Batistaeb90b782008-08-16 14:44:07 +0000435- Issue #2776: fixed small issue when handling an URL with double slash
436 after a 302 response in the case of not going through a proxy.
437
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000438- Issue #2676: in the email package, content-type parsing was hanging on
439 pathological input because of quadratic or exponential behaviour of a
440 regular expression.
441
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000442- Issue #3476: binary buffered reading through the new "io" library is now
443 thread-safe.
444
Brett Cannonbf3157b2008-08-14 05:00:03 +0000445- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
446 since mimetools itself is deprecated. Because modules are cached, all
447 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
448
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000449- Issue #3134: shutil referenced undefined WindowsError symbol.
450
Robert Schuppenies14646332008-08-10 11:01:53 +0000451- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
452 menu entries were not deleted.
453
Brett Cannon83e81842008-08-09 23:30:55 +0000454- Copied the implementation of reduce() to _functools.reduce() to have a
455 version that did not raise a DeprecationWarning under -3.
456
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000457- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
458 a MemoryError rather than silently stop the iteration.
459
Guido van Rossum59ce9012008-08-09 14:55:34 +0000460- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
461 to _sre.compile() will now be rejected. This should not affect anybody
462 since the re.compile() function never generates invalid re-bytecode.
463
Skip Montanaroa032bf42008-08-08 22:52:51 +0000464- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
465 upon first access it can be automatically initialized from the csv file if
466 it wasn't initialized during instantiation.
467
Brett Cannon3aa2a492008-08-06 22:28:09 +0000468- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
469 the reload() built-in has been removed.
470
Brett Cannon7e30b672008-08-04 21:52:25 +0000471- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000472 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +0000473 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
474 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
475 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
476 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
477 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +0000478
Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000479- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
480 raised an AttributeError.
481
Benjamin Peterson01a24322008-07-28 23:35:27 +0000482- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000483 asking for a specific length. This problem only affected files opened
484 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000485
Mark Dickinsonfe84cce2008-07-27 06:39:07 +0000486- Issue #3449: Update decimal module to use most recent specification

504- Issue #3389: Allow resolving dotted names for handlers in logging
505 configuration files.
506
507- Deprecate the sunaudio module for removal in Python 3.0.
508
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000509- Issue #3394: zipfile.writestr sets external attributes when passed a
510 file name rather than a ZipInfo instance, so files are extracted with
511 mode 0600 rather than 000 under Unix.
512
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000513- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
514 argument in python 2.5, this broke code that subclassed Popen to include its
515 own poll method. Fixed my moving _deadstate to an _internal_poll method.

523-------------
524
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000525- Issue #2235: the C API function PyObject_HashNotImplemented and its
526 interaction with the tp_hash slot (added in 2.6b2) are now documented
527
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000528- Issue #643841: The language reference now provides more detailed
529 coverage of the lookup process for special methods. The disclaimers
530 regarding lack of coverage of new-style classes have also been
531 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000534What's New in Python 2.6 beta 2?
535================================
536
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000537*Release date: 17-Jul-2008*
538
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000539Core and Builtins
540-----------------
541
Georg Brandl3e483f62008-07-16 22:57:41 +0000542- Issue #3156: Fix inconsistent behavior of the bytearray type: all
543 its methods now allow for items objects that can be converted to
544 an integer using operator.index().
545
Mark Dickinson64b7e502008-07-16 09:40:03 +0000546- Issue #3360: Fix incorrect parsing of '020000000000.0', which
547 produced a ValueError instead of giving the correct float.
548
Eric Smitha5fa5a22008-07-16 00:11:49 +0000549- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
550 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
551
Mark Dickinson7103aa42008-07-15 19:08:33 +0000552- Issue #3008: the float type has a new instance method 'float.hex'
553 and a new class method 'float.fromhex' to convert floating-point
554 numbers to and from hexadecimal strings, respectively.
555
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000556- Issue #2235: __hash__ is once again inherited by default. To allow
557 collections.Hashable to remain meaningful in the presence of the
558 default hash implementation (object.__hash__), it is now possible
559 to explicit block inheritance of hash by setting __hash__=None at
560 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
561 level.
562
Nick Coghlanb028f502008-07-13 14:52:36 +0000563- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
564 the parent module cannot be found while performing an absolute import.
565 This means that an incorrectly defined __package__ attribute will
566 now only prevent relative imports in that module rather than causing
567 all imports from that module to fail.
568
Nick Coghlan14ff9942008-07-08 14:21:42 +0000569- Issue #2517: Allow unicode messages in Exceptions again by correctly
570 bypassing the instance dictionary when looking up __unicode__ on
571 new-style classes.
572
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000573- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
574 set to a custom object whose write() method happens to install
575 another file in sys.stdout.
576
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000577- Issue #3088: Corrected a race condition in classes derived from
578 threading.local: the first member set by a thread could be saved in
579 another thread's dictionary.
580
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000581- Issue #3004: Minor change to slice.indices(): the start and stop
582 arguments are now treated identically, making the behaviour easier
583 to describe and understand. For example, slice(None, -10,
584 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
585 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
586 10, -1).
587
Georg Brandl278fc502008-07-19 12:46:12 +0000588- Issue #3219: Calling a function with repeated keyword arguments,
589 f(a=2, a=23), would not cause a syntax error. This was a regression
590 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000591
Georg Brandl278fc502008-07-19 12:46:12 +0000592- Issue #2862: Make int and float freelist management consistent with
593 other freelists. Changes their CompactFreeList apis into
594 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +0000599- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
600 api functions without holding the GIL, which could lead to a fatal
601 error when they failed.
602
Martin v. Löwisaabf4042008-08-02 07:20:25 +0000603- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

1037
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001038- On MacOS X it is now possible to install the framework in 64-bit
1039 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00001040 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001041
1042 This is controlled by the configure argument ``--with-universal-archs``:
1043
1044 - ``--with-universal-archs=all``: install 4-way universal
1045
1046 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1047
1048 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1049
1050 This option should be used in combination with ``--enable-universalsdk=``.
1051
1052 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Georg Brandl3ee81df2008-05-17 18:14:43 +00001102- Issue #1631171: Re-implement the 'warnings' module in C (the
1103 original Python code has been kept as backup). This will allow for
1104 using the 'warning's machinery in such places as the parser where
1105 use of pure Python code is not possible. Both the ``showarning()``
1106 and ``formatwarning()`` gain an optional 'line' argument which is
1107 not called by default for backwards-compatibility reasons. Setting
1108 ``warnings.showwarning()`` to an implementation that lacks support
1109 for the ``line`` argument will raise a DeprecationWarning.

1133
Gregory P. Smithd59fefb2008-04-22 08:11:33 +00001134- The getpass module has been improved on Unix. It now uses /dev/tty
1135 by default and uses stderr instead of stdout. A GetPassWarning is
1136 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001151- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00001152 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00001172- Issue #2550: The approach used by client/server code for obtaining
1173 ports to listen on in network-oriented tests has been refined in an
1174 effort to facilitate running multiple instances of the entire
1175 regression test suite in parallel without issue.
1176 test_support.bind_port() has been fixed such that it will always
1177 return a unique port -- which wasn't always the case with the
1178 previous implementation, especially if socket options had been set
1179 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1180 new implementation of bind_port() will actually raise an exception
1181 if it is passed an AF_INET/SOCK_STREAM socket with either the
1182 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1183 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1184 the socket it's been passed. This currently only applies to
1185 Windows. This option prevents any other sockets from binding to the
1186 host/port we've bound to, thus removing the possibility of the
1187 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1188 when a second SOCK_STREAM socket binds and accepts to a host/port
1189 that's already been bound by another socket. The optional preferred
1190 port parameter to bind_port() has been removed. Under no
1191 circumstances should tests be hard coding ports!
1192
1193 test_support.find_unused_port() has also been introduced, which will
1194 pass a temporary socket object to bind_port() in order to obtain an
1195 unused port. The temporary socket object is then closed and
1196 deleted, and the port is returned. This method should only be used
1197 for obtaining an unused port in order to pass to an external program
1198 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1199 a parameter to a server-oriented class that doesn't give you direct
1200 access to the underlying socket used.
1201
1202 Finally, test_support.HOST has been introduced, which should be used
1203 for the host argument of any relevant socket calls (i.e. bind and
1204 connect).

1209 test_asynchat and test_socket_ssl.
1210

1212 suite to run in parallel without issue.

1478Core and builtins
1479-----------------
1480
Fred Drakea8ee94b2008-03-01 02:45:07 +00001481- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001482 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001483
Georg Brandlad61bc82008-02-23 15:11:18 +00001484- Issue #2067: file.__exit__() now calls subclasses' close() method.
1485
1486- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001487
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001488- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001489 issue 215555 for a discussion.
1490
Eric Smitha73fbe72008-02-23 03:09:44 +00001491- Added the future_builtins module, which contains hex() and oct().
1492 These are the PEP 3127 version of these functions, designed to be
1493 compatible with the hex() and oct() builtins from Python 3.0. They
1494 differ slightly in their output formats from the existing, unchanged
1495 Python 2.6 builtins. The expected usage of the future_builtins
1496 module is:
1497 from future_builtins import hex, oct
1498
Eric Smith7ef40bf2008-02-20 23:34:22 +00001499- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1500 exponents for exponents with absolute value < 100. Follows C99
1501 standard. This is a change on Windows, which would use 3 digits.
1502 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1503 so that any alterations it does to the resulting string will be
1504 available in stringlib/formatter.h (for float.__format__).
1505
Eric Smith5a3c1352008-02-19 13:21:56 +00001506- Implemented PEP 3101, Advanced String Formatting. This adds a new
1507 builtin format(); a format() method for str and unicode; a
1508 __format__() method to object, str, unicode, int, long, float, and
1509 datetime; the class string.Formatter; and the C API
1510 PyObject_Format().
1511
Georg Brandl3ee81df2008-05-17 18:14:43 +00001512- Fixed several potential crashes, all caused by specially crafted
1513 __del__ methods exploiting objects in temporarily inconsistent
1514 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001515
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001516- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001517 prevent a possible crash: an Abstract Base Class would try to access
1518 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001519
Georg Brandl3ee81df2008-05-17 18:14:43 +00001520- Fixed repr() and str() of complex numbers with infinity or nan as
1521 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001522
Georg Brandl3ee81df2008-05-17 18:14:43 +00001523- Clear all free lists during a gc.collect() of the highest generation
1524 in order to allow pymalloc to free more arenas. Python may give back
1525 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001526
Georg Brandl3ee81df2008-05-17 18:14:43 +00001527- Issue #2045: Fix an infinite recursion triggered when printing a
1528 subclass of collections.defaultdict, if its default_factory is set
1529 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001530
Christian Heimesf75dbef2008-02-08 00:11:31 +00001531- Fixed a minor memory leak in dictobject.c. The content of the free
1532 list was not freed on interpreter shutdown.
1533
Georg Brandl3ee81df2008-05-17 18:14:43 +00001534- Limit free list of method and builtin function objects to 256
1535 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001536
Georg Brandl3ee81df2008-05-17 18:14:43 +00001537- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1538 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001539 to compact the internal free lists of pre-allocted ints and floats.
1540
Georg Brandl3ee81df2008-05-17 18:14:43 +00001541- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1542 calls. Python expected the return type int but the fork familie
1543 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001544
Georg Brandl3ee81df2008-05-17 18:14:43 +00001545- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1546 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001547
Georg Brandl3ee81df2008-05-17 18:14:43 +00001548- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1549 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001550
Georg Brandl3ee81df2008-05-17 18:14:43 +00001551- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
1552 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001553
Georg Brandl3ee81df2008-05-17 18:14:43 +00001554- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1555 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001556
Georg Brandl3ee81df2008-05-17 18:14:43 +00001557- Patch #1473257: generator objects gain a gi_code attribute. This is
1558 the same object as the func_code attribute of the function that
1559 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001560
Georg Brandl3ee81df2008-05-17 18:14:43 +00001561- Issue #1920: "while 0" statements were completely removed by the
1562 compiler, even in the presence of an "else" clause, which is
1563 supposed to be run when the condition is false. Now the compiler
1564 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001565
Guido van Rossumeead05f2008-01-24 18:21:02 +00001566- A few crashers fixed: weakref_in_del.py (issue #1377858);
1567 loosing_dict_ref.py (issue #1303614, test67.py);
1568 borrowed_ref_[34].py (not in tracker).
1569
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001570- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001571 suppressed while an extension is loaded by calling SetErrorMode in
1572 dynload_win.c. The error is still reported properly.
1573
Georg Brandl3ee81df2008-05-17 18:14:43 +00001574- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001575 several extension methods and modules do not work without unicode
1576 support.
1577
Georg Brandl26543b12008-01-21 18:36:51 +00001578- Issue #1882: when compiling code from a string, encoding cookies in the
1579 second line of code were not always recognized correctly.
1580
Georg Brandl14404b62008-01-19 19:27:05 +00001581- Issue #1679: "0x" was taken as a valid integer literal.
1582
Georg Brandl6caad7d2008-01-26 14:19:22 +00001583- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001584 added.
1585
Christian Heimesc94e2b52008-01-14 04:13:37 +00001586- sys.float_info / PyFloat_GetInfo: The floating point information
1587 object was converted from a dict to a specialized structseq object.
1588
Georg Brandl3ee81df2008-05-17 18:14:43 +00001589- Patch #1816: Added sys.flags structseq. It exposes the status of
1590 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001591
Georg Brandl3ee81df2008-05-17 18:14:43 +00001592- Objects/structseq.c: Implemented new structseq representation. The
1593 patch makes structseqs (e.g. the return value of os.stat) more
1594 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001595
Georg Brandl3ee81df2008-05-17 18:14:43 +00001596- Patch #1700288: added a type attribute cache that caches method
1597 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001598
Neal Norwitz3fc15b82008-01-10 05:42:58 +00001599- Bug #1776: __import__() no longer accepts filenames on any platform.
1600 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00001601

1603
Georg Brandl3ee81df2008-05-17 18:14:43 +00001604- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
1605 envvar and sys.dont_write_bytecode attribute. All these can be set
1606 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001607
Georg Brandl3ee81df2008-05-17 18:14:43 +00001608- Improve some exception messages when Windows fails to load an
1609 extension module. Now we get for example '%1 is not a valid Win32
1610 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00001611
Georg Brandl3ee81df2008-05-17 18:14:43 +00001612- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001614- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
1615 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00001616
Christian Heimes0a8143f2007-12-18 23:22:54 +00001617- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001618 and INF. float("nan"), float("inf") and float("-inf") now work on
1619 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001620
Georg Brandl3ee81df2008-05-17 18:14:43 +00001621- Compiler now generates simpler and faster code for dictionary
1622 literals. The oparg for BUILD_MAP now indicates an estimated
1623 dictionary size. There is a new opcode, STORE_MAP, for adding
1624 entries to the dictionary.

1642 running, and if the deallocation of its frames somehow calls the
1643 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00001644

Georg Brandl3ee81df2008-05-17 18:14:43 +00001658- Issue #1265: Fix a problem with sys.settrace, if the tracing
1659 function uses a generator expression when at the same time the
1660 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00001661
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00001662- sets and frozensets now have an isdisjoint() method.
1663
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00001664- optimize the performance of builtin.sum().

Neal Norwitz44f326e2007-10-05 05:29:17 +00001666- Fix warnings found by the new version of the Coverity checker.
1667
Georg Brandl3ee81df2008-05-17 18:14:43 +00001668- The enumerate() builtin function is no longer bounded to sequences
1669 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1670 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001671
Georg Brandl3ee81df2008-05-17 18:14:43 +00001672- Issue #1686386: Tuple's tp_repr did not take into account the
1673 possibility of having a self-referential tuple, which is possible
1674 from C code. Nor did object's tp_str consider that a type's tp_str
1675 could do something that could lead to an inifinite recursion.
1676 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1677 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001678
Georg Brandl3ee81df2008-05-17 18:14:43 +00001679- Issue #1164: It was possible to trigger deadlock when using the
1680 'print' statement to write to a file since the GIL was not released
1681 as needed. Now PyObject_Print() does the right thing along with
1682 various tp_print implementations of the built-in types and those in
1683 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00001684
Georg Brandl3ee81df2008-05-17 18:14:43 +00001685- Issue #1147: Exceptions were directly allowing string exceptions in
1686 their throw() method even though string exceptions no longer
1687 allowed.

Brett Cannon1e534b52007-09-07 04:18:30 +00001692- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001693 PyObject_Call() never calling back out to Python code to trigger
1694 recursion depth updates/checks. Required the creation of a static
1695 RuntimeError instance in case normalizing an exception put the
1696 recursion check value past its limit. Fixes crashers
1697 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00001698

Neal Norwitz0ac60192007-05-27 04:08:54 +00001712- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00001713 __*__ attributes. (Some already existed, e.g., __doc__ and
1714 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00001715
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00001716- Add -3 option to the interpreter to warn about features that are
1717 deprecated and will be changed/removed in Python 3.0.
1718

1720 calls.
1721
Collin Winter62903052007-05-18 23:11:24 +00001722- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00001723 "except E as target:". This is to provide forwards compatibility
1724 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00001725
Brett Cannon229cee22007-05-05 01:34:02 +00001726- Deprecate BaseException.message as per PEP 352.
1727
Georg Brandl3ee81df2008-05-17 18:14:43 +00001728- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00001729 inherited from a builtin base.
1730
Vinay Sajip8549ce32007-05-06 17:53:37 +00001731- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00001732 setting a plain string, ie don't expand to single letter identifiers.
1733
Raymond Hettinger13936692007-04-11 18:40:58 +00001734- Request #1191699: Slices can now be pickled.
1735
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00001736- Request #1193128: str.translate() now allows a None argument for
1737 translations that only remove characters without re-mapping the
1738 remaining characters.
1739
Georg Brandl5cb76c12007-03-21 09:00:39 +00001740- Patch #1682205: a TypeError while unpacking an iterable is no longer
1741 masked by a generic one with the message "unpack non-sequence".
1742
Neal Norwitzaa754b72007-03-21 06:39:48 +00001743- Remove unused file Python/fmod.c.
1744
Guido van Rossum143b5642007-03-23 04:58:42 +00001745- Bug #1683368: The object.__init__() and object.__new__() methods are
1746 now stricter in rejecting excess arguments. The only time when
1747 either allows excess arguments is when it is not overridden and the
1748 other one is. For backwards compatibility, when both are
1749 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00001750 warning later). Also, type.__init__() insists on the same signature
1751 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00001752
Georg Brandl3ee81df2008-05-17 18:14:43 +00001753- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
1754 object to complex using its __complex__() method before falling back
1755 to the __float__() method. Therefore, the functions in the cmath
1756 module now can operate on objects that define a __complex__()
1757 method.
Georg Brandl2b869942007-03-17 16:08:45 +00001758
Georg Brandl3ee81df2008-05-17 18:14:43 +00001759- Patch #1623563: allow __class__ assignment for classes with
1760 __slots__. The old and the new class are still required to have the
1761 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00001762

1767 ``object.__reduce_ex__()`` is called with an object that is faking
1768 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00001769
Georg Brandl3ee81df2008-05-17 18:14:43 +00001770- Patch #1680015: Don't modify __slots__ tuple if it contains an

Georg Brandl5240d742007-03-13 20:46:32 +00001773- Patch #1444529: the builtin compile() now accepts keyword arguments.
1774
Georg Brandl7b9c5552007-03-12 14:30:05 +00001775- Bug #1678647: write a newline after printing an exception in any
1776 case, even when converting the value to a string failed.
1777
Georg Brandl871f1bc2007-03-12 13:17:36 +00001778- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00001779 its argument, if it exists. If not, it will work like before. This
1780 allows customizing the output of dir() in the presence of a
1781 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00001782
Collin Winter276887b2007-03-12 16:11:39 +00001783- Patch #922167: Python no longer segfaults when faced with infinitely
1784 self-recursive reload() calls (as reported by bug #742342).
1785

1790 parthensized forms. This means complex(repr(x)) now works instead of
1791 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00001792
Georg Brandlaa2321b2007-03-07 00:40:28 +00001793- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00001794 makes the filenames the warning module prints much more sensible
1795 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00001796
Georg Brandl49aafc92007-03-07 00:34:46 +00001797- Variant of patch #697613: don't exit the interpreter on a SystemExit
1798 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00001799 variable is given, but break into the interactive interpreter just
1800 like on other exceptions or normal program exit.

1806 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00001807
Georg Brandl0fca97a2007-03-05 22:28:08 +00001808- Patch #1674228: when assigning a slice (old-style), check for the
1809 sq_ass_slice instead of the sq_slice slot.
1810
Georg Brandl3ee81df2008-05-17 18:14:43 +00001811- When printing an unraisable error, don't print exceptions. before
1812 the name. This duplicates the behavior whening normally printing
1813 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00001814
Georg Brandl3ee81df2008-05-17 18:14:43 +00001815- Bug #1653736: Properly discard third argument to

Georg Brandl3ee81df2008-05-17 18:14:43 +00001821- Bug #1377858: Fix the segfaulting of the interpreter when an object
1822 created a weakref on itself during a __del__ call for new-style
1823 classes (classic classes still have the bug).

2422 Python would crash instead of raising an error.
2423

2425 returned string up to the first NUL character.

2436
Georg Brandl3ee81df2008-05-17 18:14:43 +00002437- unittest now verifies more of its assumptions. In particular,
2438 TestCase and TestSuite subclasses (not instances) are no longer
2439 accepted in TestSuite.addTest(). This should cause no
2440 incompatibility since it never made sense with ordinary subclasses
2441 -- the failure just occurred later, with a more cumbersome
2442 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002723- Issue #829951: In the smtplib module, SMTP.starttls() now complies
2724 with RFC 3207 and forgets any knowledge obtained from the server not
2725 obtained from the TLS negotiation itself. Patch contributed by Bill
2726 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00002727
Georg Brandl3ee81df2008-05-17 18:14:43 +00002728- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00002729 that the SMTP.starttls() caller no longer needs to call ehlo()
2730 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00002731 does not claim to support starttls. Adds the
2732 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

2813 complex, tuple, list, dict, set, and frozenset. Formerly, it would
2814 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00002831 time so that opening a database previously created with the DB_DUP
2832 or DB_DUPSORT flag set will keep the proper behavior on subsequent
2833 opens. Specifically: dictionary assignment to a DB object will
2834 replace all values for a given key when the database allows
2835 duplicate values. DB users should use DB.put(k, v) when they want
2836 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00002837

2843 characters with ASCII value less than 32. Also, it correctly quotes
2844 dots only if they occur on a single line, as opposed to the previous
2845 behavior of quoting dots if they are the second character of any
2846 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00002847

3169-----
3170
Georg Brandl3ee81df2008-05-17 18:14:43 +00003171- Unified naming convention for free lists and their limits. All free
3172 lists in Object/ are named ``free_list``, the counter ``numfree``
3173 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3174 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003175
Georg Brandl3ee81df2008-05-17 18:14:43 +00003176- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3177 to ``PyTuple_SetItem``, it can be used to populate a brand new
3178 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003179
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003180- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003181
Georg Brandl3ee81df2008-05-17 18:14:43 +00003182- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3183 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3184 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003185
3186- Patch #1720595: add T_BOOL to the range of structmember types.
3187
3188- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3189 ``PyFloat_GetInfo()`` to the float API.
3190
Georg Brandl3ee81df2008-05-17 18:14:43 +00003191- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3192 of w# format code incorrectly truncated the length to an int, even
3193 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3194 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3197 Py_TYPE and Py_REFCNT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003198
Georg Brandl3ee81df2008-05-17 18:14:43 +00003199- PEP 3123: Provide forward compatibility with Python 3.0, while
3200 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3201 and PyVarObject_HEAD_INIT.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003202
Georg Brandl3ee81df2008-05-17 18:14:43 +00003203- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not
3204 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003205
3206- Patch #1733960: Allow T_LONGLONG to accept ints.
3207
3208- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
3209
Christian Heimes000a0742008-01-03 22:16:32 +00003210- Added a new API function ``PyImport_ImportModuleNoBlock``.
3211
Georg Brandl6caad7d2008-01-26 14:19:22 +00003212- Bug #1637022: Prefix AST symbols with _Py_.
3213
3214- Fix some leftovers from the conversion from int to Py_ssize_t
3215 (relevant to strings and sequences of more than 2**31 items).
3216
3217- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3218 outside of pystate.c and should not be necessary.
3219
Georg Brandl3ee81df2008-05-17 18:14:43 +00003220- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3221 absolute imports. In earlier versions they might have used relative
3222 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003223
Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3225 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003226
Georg Brandl3ee81df2008-05-17 18:14:43 +00003227- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx
3228 macro so it can be used as an expression.

3233
Georg Brandl3ee81df2008-05-17 18:14:43 +00003234- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3235 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3236 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3237 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003238
Georg Brandl3ee81df2008-05-17 18:14:43 +00003239- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE and
3240 _CRT_NONSTDC_NO_DEPRECATE.

Brett Cannon791d56f2007-05-31 19:40:42 +00003250- buildtools now raises a DeprecationWarning.
3251
Georg Brandl3ee81df2008-05-17 18:14:43 +00003252- Removed the macfs module. It had been deprecated since Python 2.5.
3253 This lead to the deprecation of macostools.touched() as it relied
3254 solely on macfs and was a no-op under OS X.
