14
Amaury Forgeot d'Arc74b458c2008-11-22 20:06:51 +000015- Issue #3996: On Windows, the PyOS_CheckStack function would cause the

18
Benjamin Peterson71ce9e72008-11-21 22:52:21 +000019- Issue #4367: Python would segfault during compiling when the unicodedata
20 module couldn't be imported and \N escapes were present.
21
Benjamin Peterson866eba92008-11-19 22:05:53 +000022- Issue #4348: Some bytearray methods returned that didn't cause any change to

198
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000199- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
200 PyString_FromFormat or PyErr_Format to display size_t values. The macro
201 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
202 ``printf`` function, whereas PyString_FromFormat has an independent
203 implementation and uses "%zd" on all platforms for size_t values.
204 This makes a difference on win64, where ``printf`` needs "%Id" to display
205 64bit values.
206
Benjamin Peterson97179b02008-09-09 20:55:01 +0000207- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

211 object; previously an int would be returned for small values. the __long__
212 method is allowed to return either an int or a long, but the behaviour of
213 float objects should not change to respect backward compatibility.
214
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000215- Issue #3751: str.rpartition would perform a left-partition when called with

Vinay Sajip35e3b032008-09-01 14:33:59 +0000221 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000222 was correctly parsed but parsing of subsequent arguments failed.
223
Vinay Sajip35e3b032008-09-01 14:33:59 +0000224- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000225 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
226 mechanism. In the process, fix a bug where isinstance() and issubclass(),
227 when given a tuple of classes as second argument, were looking up
228 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
229 type object.

322-----------------
323
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +0000324- Issue #2975: When compiling several extension modules with Visual Studio 2008
325 from the same python interpreter, some environment variables would grow
326 without limit.
327
Benjamin Peterson37346b22008-08-23 20:27:43 +0000328- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
329 exploitation of poor argument checking.
330
Gerhard Häringef2276b2008-09-12 13:54:06 +0000331- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
332
Gerhard Häring6e1afcf2008-09-12 18:58:57 +0000333- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
334 remaining ones have "pysqlite_" prefix.
335
Gerhard Häringe6872eb2008-09-12 22:33:22 +0000336- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves
337 concurrent access to the same SQLite database from multiple
338 threads/processes.

Nick Coghland2e09382008-09-11 12:11:06 +0000343- Issue #3781: Add test.test_support.check_warnings() as a convenience
344 wrapper for warnings.catch_warnings() that makes it easier to check
345 that expected warning messages are being reported.
346
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +0000347- Issue #3796: Some tests functions were not enabled in test_float.
348

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000365What's New in Python 2.6 beta 3?
366================================
367
Barry Warsaw07a4a382008-08-21 01:15:08 +0000368*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000369
370Core and Builtins
371-----------------
372
Guido van Rossumf8402962008-08-20 15:01:50 +0000373- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
374 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
375 extensions do not automatically benefit from the class attribute
376 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
377 to their tp_flags field if they care. This is a backwards
378 compatibility feature; in 3.0, all types will use the cache by
379 default.
380
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000381- Keyword arguments can now follow starred arguments. (``f(a, *args,
382 keyword=23)`` is now valid syntax.)
383
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000384- ctypes function pointers that are COM methods have a boolean True
385 value again.
386
Martin v. Löwisf91d46a2008-08-12 14:49:50 +0000387- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
388 by denying s# to parse objects that have a releasebuffer procedure,
389 and introducing s*.
390
Georg Brandl1e13ea92008-08-11 09:07:59 +0000391- Issue #3537: Fix an assertion failure when an empty but presized dict
392 object was stored in the freelist.
393
Mark Dickinsonb6467572008-08-04 21:30:09 +0000394- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
395 ValueError consistently across platforms.
396
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000397- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
398 (64bit Unix, for example), unichr() would truncate its argument and return
399 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
400
Neal Norwitze7d8be82008-07-31 17:17:14 +0000401- Apply security patches from Apple.
402
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000403- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
404 PyErr_ExceptionMatches returns 0 when an exception occurs there.
405
Antoine Pitrou92f82162008-07-25 22:22:08 +0000406- Issue #1819: function calls with several named parameters are now on
407 average 35% faster (as measured by pybench).
408
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000409- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
410 the python debugger steps into a class statement: the free variables (local
411 variables defined in an outer scope) would be deleted from the outer scope.
412
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000413- Issue #2620: Overflow checking when allocating or reallocating memory
414 was not always being done properly in some python types and extension
415 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
416 all been updated to perform better checks and places in the code that
417 would previously leak memory on the error path when such an allocation
418 failed have been fixed.
419
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000420Library
421-------
422
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +0000423- Issue #3612: Added some missing basic types in ctypes.wintypes.
424
Benjamin Petersone977ad42008-08-20 01:42:01 +0000425- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
426 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
427
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000428- Issue #2234: distutils failed for some versions of the cygwin compiler. The
429 version reported by these tools does not necessarily follow the python
430 version numbering scheme, so the module is less strict when parsing it.
431
Nick Coghlanf70385a2008-08-18 12:42:46 +0000432- Issue #2235: Added Py3k warnings for types which will become unhashable
433 under the stricter __hash__ inheritance rules in 3.0. Several types
434 which did not meet the rules for hash invariants and were already
435 unhashable in 3.0 have now been explicitly flagged as unhashable in
436 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
437 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
438
Brett Cannon88f801d2008-08-18 00:46:22 +0000439- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

445
Brett Cannon25c9d6a2008-08-17 22:10:11 +0000446- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
447
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +0000448- Issue #3575: Incremental decoder's decode function now takes bytearray
449 by using 's*' instead of 't#'.
450
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +0000451- Issue #2222: Fixed reference leak when occured os.rename()
452 fails unicode conversion on 2nd parameter. (windows only)
453
Facundo Batista94f243a2008-08-17 03:38:39 +0000454- Issue 2464. urllib2 now supports a malformation in the URL received
455 in a redirect.
456
Brett Cannonabe423e2008-08-16 21:47:07 +0000457- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +0000458 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +0000459
Facundo Batistaeb90b782008-08-16 14:44:07 +0000460- Issue #2776: fixed small issue when handling an URL with double slash
461 after a 302 response in the case of not going through a proxy.
462
Antoine Pitroub90a8be2008-08-15 21:03:21 +0000463- Issue #2676: in the email package, content-type parsing was hanging on
464 pathological input because of quadratic or exponential behaviour of a
465 regular expression.
466
Antoine Pitrou11ec65d2008-08-14 21:04:30 +0000467- Issue #3476: binary buffered reading through the new "io" library is now
468 thread-safe.
469
Brett Cannonbf3157b2008-08-14 05:00:03 +0000470- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
471 since mimetools itself is deprecated. Because modules are cached, all
472 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
473
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +0000474- Issue #3134: shutil referenced undefined WindowsError symbol.
475
Robert Schuppenies14646332008-08-10 11:01:53 +0000476- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
477 menu entries were not deleted.
478
Brett Cannon83e81842008-08-09 23:30:55 +0000479- Copied the implementation of reduce() to _functools.reduce() to have a
480 version that did not raise a DeprecationWarning under -3.
481
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000482- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
483 a MemoryError rather than silently stop the iteration.
484
Guido van Rossum59ce9012008-08-09 14:55:34 +0000485- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
486 to _sre.compile() will now be rejected. This should not affect anybody
487 since the re.compile() function never generates invalid re-bytecode.
488
Skip Montanaroa032bf42008-08-08 22:52:51 +0000489- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
490 upon first access it can be automatically initialized from the csv file if
491 it wasn't initialized during instantiation.
492
Brett Cannon3aa2a492008-08-06 22:28:09 +0000493- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
494 the reload() built-in has been removed.
495
Brett Cannon7e30b672008-08-04 21:52:25 +0000496- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +0000497 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Lars Gustäbel727bd0b2008-08-02 11:26:39 +0000504- Issue #3039: Fix tarfile.TarFileCompat.writestr() which always
505 raised an AttributeError.
506
Benjamin Peterson01a24322008-07-28 23:35:27 +0000507- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +0000508 asking for a specific length. This problem only affected files opened
509 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000510

532- Deprecate the sunaudio module for removal in Python 3.0.
533
Antoine Pitrou5fdfa3e2008-07-25 19:42:26 +0000534- Issue #3394: zipfile.writestr sets external attributes when passed a
535 file name rather than a ZipInfo instance, so files are extracted with
536 mode 0600 rather than 000 under Unix.
537
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000538- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
539 argument in python 2.5, this broke code that subclassed Popen to include its
540 own poll method. Fixed my moving _deadstate to an _internal_poll method.

548-------------
549
Nick Coghlan6e8fef02008-08-18 13:14:22 +0000550- Issue #2235: the C API function PyObject_HashNotImplemented and its
551 interaction with the tp_hash slot (added in 2.6b2) are now documented
552
Nick Coghlan2a0c2b12008-08-04 12:47:17 +0000553- Issue #643841: The language reference now provides more detailed
554 coverage of the lookup process for special methods. The disclaimers
555 regarding lack of coverage of new-style classes have also been
556 removed, since the coverage is now fairly reasonable.

Raymond Hettingere3ae6552008-06-20 04:18:15 +0000559What's New in Python 2.6 beta 2?
560================================
561
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000562*Release date: 17-Jul-2008*
563
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000564Core and Builtins
565-----------------
566
Georg Brandl3e483f62008-07-16 22:57:41 +0000567- Issue #3156: Fix inconsistent behavior of the bytearray type: all
568 its methods now allow for items objects that can be converted to
569 an integer using operator.index().
570
Mark Dickinson64b7e502008-07-16 09:40:03 +0000571- Issue #3360: Fix incorrect parsing of '020000000000.0', which
572 produced a ValueError instead of giving the correct float.
573
Eric Smitha5fa5a22008-07-16 00:11:49 +0000574- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
575 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
576
Mark Dickinson7103aa42008-07-15 19:08:33 +0000577- Issue #3008: the float type has a new instance method 'float.hex'
578 and a new class method 'float.fromhex' to convert floating-point
579 numbers to and from hexadecimal strings, respectively.
580
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000581- Issue #2235: __hash__ is once again inherited by default. To allow
582 collections.Hashable to remain meaningful in the presence of the
583 default hash implementation (object.__hash__), it is now possible
584 to explicit block inheritance of hash by setting __hash__=None at
585 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
586 level.
587
Nick Coghlanb028f502008-07-13 14:52:36 +0000588- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
589 the parent module cannot be found while performing an absolute import.
590 This means that an incorrectly defined __package__ attribute will
591 now only prevent relative imports in that module rather than causing
592 all imports from that module to fail.
593
Nick Coghlan14ff9942008-07-08 14:21:42 +0000594- Issue #2517: Allow unicode messages in Exceptions again by correctly
595 bypassing the instance dictionary when looking up __unicode__ on
596 new-style classes.
597
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000598- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
599 set to a custom object whose write() method happens to install
600 another file in sys.stdout.
601
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000602- Issue #3088: Corrected a race condition in classes derived from
603 threading.local: the first member set by a thread could be saved in
604 another thread's dictionary.
605
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000606- Issue #3004: Minor change to slice.indices(): the start and stop
607 arguments are now treated identically, making the behaviour easier
608 to describe and understand. For example, slice(None, -10,
609 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
610 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
611 10, -1).
612
Georg Brandl278fc502008-07-19 12:46:12 +0000613- Issue #3219: Calling a function with repeated keyword arguments,
614 f(a=2, a=23), would not cause a syntax error. This was a regression
615 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000616
Georg Brandl278fc502008-07-19 12:46:12 +0000617- Issue #2862: Make int and float freelist management consistent with
618 other freelists. Changes their CompactFreeList apis into
619 ClearFreeList apis and calls them via gc.collect().

622-------
623
Thomas Heller57adf222008-08-14 19:10:48 +0000624- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
625 api functions without holding the GIL, which could lead to a fatal

Georg Brandl5cc774e2008-06-11 20:28:06 +00001065 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00001066
1067 This is controlled by the configure argument ``--with-universal-archs``:
1068
1069 - ``--with-universal-archs=all``: install 4-way universal
1070
1071 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
1072
1073 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
1074
1075 This option should be used in combination with ``--enable-universalsdk=``.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001127- Issue #1631171: Re-implement the 'warnings' module in C (the
1128 original Python code has been kept as backup). This will allow for
1129 using the 'warning's machinery in such places as the parser where
1130 use of pure Python code is not possible. Both the ``showarning()``
1131 and ``formatwarning()`` gain an optional 'line' argument which is
1132 not called by default for backwards-compatibility reasons. Setting
1133 ``warnings.showwarning()`` to an implementation that lacks support
1134 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001189- Issue #2385: distutils.core.run_script() makes __file__ available,
1190 so the controlled environment will more closely mirror the typical
1191 script environment. This supports setup.py scripts that refer to
1192 data files.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001197- Issue #2550: The approach used by client/server code for obtaining
1198 ports to listen on in network-oriented tests has been refined in an
1199 effort to facilitate running multiple instances of the entire
1200 regression test suite in parallel without issue.
1201 test_support.bind_port() has been fixed such that it will always
1202 return a unique port -- which wasn't always the case with the
1203 previous implementation, especially if socket options had been set
1204 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1205 new implementation of bind_port() will actually raise an exception
1206 if it is passed an AF_INET/SOCK_STREAM socket with either the
1207 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1208 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1209 the socket it's been passed. This currently only applies to
1210 Windows. This option prevents any other sockets from binding to the
1211 host/port we've bound to, thus removing the possibility of the
1212 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1213 when a second SOCK_STREAM socket binds and accepts to a host/port
1214 that's already been bound by another socket. The optional preferred
1215 port parameter to bind_port() has been removed. Under no
1216 circumstances should tests be hard coding ports!
1217
1218 test_support.find_unused_port() has also been introduced, which will
1219 pass a temporary socket object to bind_port() in order to obtain an
1220 unused port. The temporary socket object is then closed and
1221 deleted, and the port is returned. This method should only be used
1222 for obtaining an unused port in order to pass to an external program
1223 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1224 a parameter to a server-oriented class that doesn't give you direct
1225 access to the underlying socket used.
1226
1227 Finally, test_support.HOST has been introduced, which should be used
1228 for the host argument of any relevant socket calls (i.e. bind and
1229 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001230
1231 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001232 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001233 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1234 test_asynchat and test_socket_ssl.
1235
Georg Brandl3ee81df2008-05-17 18:14:43 +00001236 It is now possible for multiple instances of the regression test
1237 suite to run in parallel without issue.

1503Core and builtins
1504-----------------
1505
Fred Drakea8ee94b2008-03-01 02:45:07 +00001506- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00001507 644. The mode is now inherited from the py file.
Christian Heimes40346852008-02-23 17:52:07 +00001508
Georg Brandlad61bc82008-02-23 15:11:18 +00001509- Issue #2067: file.__exit__() now calls subclasses' close() method.
1510
1511- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00001512
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001513- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00001514 issue 215555 for a discussion.
1515
Eric Smitha73fbe72008-02-23 03:09:44 +00001516- Added the future_builtins module, which contains hex() and oct().
1517 These are the PEP 3127 version of these functions, designed to be
1518 compatible with the hex() and oct() builtins from Python 3.0. They
1519 differ slightly in their output formats from the existing, unchanged
1520 Python 2.6 builtins. The expected usage of the future_builtins
1521 module is:
1522 from future_builtins import hex, oct
1523
Eric Smith7ef40bf2008-02-20 23:34:22 +00001524- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1525 exponents for exponents with absolute value < 100. Follows C99
1526 standard. This is a change on Windows, which would use 3 digits.
1527 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1528 so that any alterations it does to the resulting string will be
1529 available in stringlib/formatter.h (for float.__format__).
1530
Eric Smith5a3c1352008-02-19 13:21:56 +00001531- Implemented PEP 3101, Advanced String Formatting. This adds a new
1532 builtin format(); a format() method for str and unicode; a
1533 __format__() method to object, str, unicode, int, long, float, and
1534 datetime; the class string.Formatter; and the C API
1535 PyObject_Format().
1536
Georg Brandl3ee81df2008-05-17 18:14:43 +00001537- Fixed several potential crashes, all caused by specially crafted
1538 __del__ methods exploiting objects in temporarily inconsistent
1539 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00001540
Vinay Sajipb7edfc42008-04-02 21:10:23 +00001541- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00001542 prevent a possible crash: an Abstract Base Class would try to access
1543 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00001544
Georg Brandl3ee81df2008-05-17 18:14:43 +00001545- Fixed repr() and str() of complex numbers with infinity or nan as
1546 real or imaginary part.
Christian Heimes2f0da532008-02-15 06:57:08 +00001547
Georg Brandl3ee81df2008-05-17 18:14:43 +00001548- Clear all free lists during a gc.collect() of the highest generation
1549 in order to allow pymalloc to free more arenas. Python may give back
1550 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001551
Georg Brandl3ee81df2008-05-17 18:14:43 +00001552- Issue #2045: Fix an infinite recursion triggered when printing a
1553 subclass of collections.defaultdict, if its default_factory is set
1554 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00001555
Christian Heimesf75dbef2008-02-08 00:11:31 +00001556- Fixed a minor memory leak in dictobject.c. The content of the free
1557 list was not freed on interpreter shutdown.
1558
Georg Brandl3ee81df2008-05-17 18:14:43 +00001559- Limit free list of method and builtin function objects to 256
1560 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001561
Georg Brandl3ee81df2008-05-17 18:14:43 +00001562- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1563 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001564 to compact the internal free lists of pre-allocted ints and floats.
1565
Georg Brandl3ee81df2008-05-17 18:14:43 +00001566- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1567 calls. Python expected the return type int but the fork familie
1568 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00001569
Georg Brandl3ee81df2008-05-17 18:14:43 +00001570- Issue #1678380: Fix a bug that identifies 0j and -0j when they
1571 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00001572
Georg Brandl3ee81df2008-05-17 18:14:43 +00001573- Issue #2025: Add tuple.count() and tuple.index() methods to comply
1574 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00001575

1577 linebreak detection
Christian Heimes4d4f2702008-01-30 11:32:37 +00001578
Georg Brandl3ee81df2008-05-17 18:14:43 +00001579- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
1580 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00001581
Georg Brandl3ee81df2008-05-17 18:14:43 +00001582- Patch #1473257: generator objects gain a gi_code attribute. This is
1583 the same object as the func_code attribute of the function that
1584 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001585
Georg Brandl3ee81df2008-05-17 18:14:43 +00001586- Issue #1920: "while 0" statements were completely removed by the
1587 compiler, even in the presence of an "else" clause, which is
1588 supposed to be run when the condition is false. Now the compiler
1589 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001590
Guido van Rossumeead05f2008-01-24 18:21:02 +00001591- A few crashers fixed: weakref_in_del.py (issue #1377858);
1592 loosing_dict_ref.py (issue #1303614, test67.py);
1593 borrowed_ref_[34].py (not in tracker).
1594
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001595- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001596 suppressed while an extension is loaded by calling SetErrorMode in
1597 dynload_win.c. The error is still reported properly.
1598
Georg Brandl3ee81df2008-05-17 18:14:43 +00001599- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001600 several extension methods and modules do not work without unicode
1601 support.
1602
Georg Brandl26543b12008-01-21 18:36:51 +00001603- Issue #1882: when compiling code from a string, encoding cookies in the
1604 second line of code were not always recognized correctly.
1605
Georg Brandl14404b62008-01-19 19:27:05 +00001606- Issue #1679: "0x" was taken as a valid integer literal.
1607
Georg Brandl6caad7d2008-01-26 14:19:22 +00001608- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001609 added.
1610
Christian Heimesc94e2b52008-01-14 04:13:37 +00001611- sys.float_info / PyFloat_GetInfo: The floating point information
1612 object was converted from a dict to a specialized structseq object.
1613
Georg Brandl3ee81df2008-05-17 18:14:43 +00001614- Patch #1816: Added sys.flags structseq. It exposes the status of
1615 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001616
Georg Brandl3ee81df2008-05-17 18:14:43 +00001617- Objects/structseq.c: Implemented new structseq representation. The
1618 patch makes structseqs (e.g. the return value of os.stat) more
1619 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001620
Georg Brandl3ee81df2008-05-17 18:14:43 +00001621- Patch #1700288: added a type attribute cache that caches method
1622 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001623

1631 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00001632
Georg Brandl3ee81df2008-05-17 18:14:43 +00001633- Improve some exception messages when Windows fails to load an
1634 extension module. Now we get for example '%1 is not a valid Win32
1635 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00001642- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00001643 and INF. float("nan"), float("inf") and float("-inf") now work on
1644 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00001645
Georg Brandl3ee81df2008-05-17 18:14:43 +00001646- Compiler now generates simpler and faster code for dictionary
1647 literals. The oparg for BUILD_MAP now indicates an estimated
1648 dictionary size. There is a new opcode, STORE_MAP, for adding
1649 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001697- Issue #1686386: Tuple's tp_repr did not take into account the
1698 possibility of having a self-referential tuple, which is possible
1699 from C code. Nor did object's tp_str consider that a type's tp_str
1700 could do something that could lead to an inifinite recursion.
1701 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1702 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001703
Georg Brandl3ee81df2008-05-17 18:14:43 +00001704- Issue #1164: It was possible to trigger deadlock when using the
1705 'print' statement to write to a file since the GIL was not released
1706 as needed. Now PyObject_Print() does the right thing along with
1707 various tp_print implementations of the built-in types and those in
1708 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00001709
Georg Brandl3ee81df2008-05-17 18:14:43 +00001710- Issue #1147: Exceptions were directly allowing string exceptions in
1711 their throw() method even though string exceptions no longer
1712 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00001713
Georg Brandl3ee81df2008-05-17 18:14:43 +00001714- Issue #1096: Prevent a segfault from getting the repr of a very
1715 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00001716
Brett Cannon1e534b52007-09-07 04:18:30 +00001717- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00001718 PyObject_Call() never calling back out to Python code to trigger
1719 recursion depth updates/checks. Required the creation of a static
1720 RuntimeError instance in case normalizing an exception put the
1721 recursion check value past its limit. Fixes crashers
1722 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00001723
Georg Brandl3ee81df2008-05-17 18:14:43 +00001724- Patch #1031213: Decode source line in SyntaxErrors back to its

1728 with %G.
1729
Georg Brandl3ee81df2008-05-17 18:14:43 +00001730- Prevent expandtabs() on string and unicode objects from causing a

Neal Norwitz0ac60192007-05-27 04:08:54 +00001737- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00001738 __*__ attributes. (Some already existed, e.g., __doc__ and
1739 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00001740
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00001741- Add -3 option to the interpreter to warn about features that are
1742 deprecated and will be changed/removed in Python 3.0.
1743
Georg Brandl2134e752007-05-21 20:34:16 +00001744- Patch #1686487: you can now pass any mapping after '**' in function
1745 calls.
1746
Collin Winter62903052007-05-18 23:11:24 +00001747- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00001748 "except E as target:". This is to provide forwards compatibility
1749 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00001750
Brett Cannon229cee22007-05-05 01:34:02 +00001751- Deprecate BaseException.message as per PEP 352.
1752
Georg Brandl3ee81df2008-05-17 18:14:43 +00001753- Issue #1303614: don't expose object's __dict__ when the dict is
Armin Rigo9790a272007-05-02 19:23:31 +00001754 inherited from a builtin base.
1755
Vinay Sajip8549ce32007-05-06 17:53:37 +00001756- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00001757 setting a plain string, ie don't expand to single letter identifiers.
1758
Raymond Hettinger13936692007-04-11 18:40:58 +00001759- Request #1191699: Slices can now be pickled.
1760
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00001761- Request #1193128: str.translate() now allows a None argument for
1762 translations that only remove characters without re-mapping the
1763 remaining characters.
1764
Georg Brandl5cb76c12007-03-21 09:00:39 +00001765- Patch #1682205: a TypeError while unpacking an iterable is no longer
1766 masked by a generic one with the message "unpack non-sequence".
1767
Neal Norwitzaa754b72007-03-21 06:39:48 +00001768- Remove unused file Python/fmod.c.
1769
Guido van Rossum143b5642007-03-23 04:58:42 +00001770- Bug #1683368: The object.__init__() and object.__new__() methods are
1771 now stricter in rejecting excess arguments. The only time when
1772 either allows excess arguments is when it is not overridden and the
1773 other one is. For backwards compatibility, when both are
1774 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00001775 warning later). Also, type.__init__() insists on the same signature
1776 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00001777
Georg Brandl3ee81df2008-05-17 18:14:43 +00001778- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
1779 object to complex using its __complex__() method before falling back
1780 to the __float__() method. Therefore, the functions in the cmath
1781 module now can operate on objects that define a __complex__()
1782 method.
Georg Brandl2b869942007-03-17 16:08:45 +00001783
Georg Brandl3ee81df2008-05-17 18:14:43 +00001784- Patch #1623563: allow __class__ assignment for classes with
1785 __slots__. The old and the new class are still required to have the
1786 same slot names.

1792 ``object.__reduce_ex__()`` is called with an object that is faking
1793 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00001794
Georg Brandl3ee81df2008-05-17 18:14:43 +00001795- Patch #1680015: Don't modify __slots__ tuple if it contains an

1799
Georg Brandl7b9c5552007-03-12 14:30:05 +00001800- Bug #1678647: write a newline after printing an exception in any
1801 case, even when converting the value to a string failed.
1802
Georg Brandl871f1bc2007-03-12 13:17:36 +00001803- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00001804 its argument, if it exists. If not, it will work like before. This
1805 allows customizing the output of dir() in the presence of a
1806 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00001807
Collin Winter276887b2007-03-12 16:11:39 +00001808- Patch #922167: Python no longer segfaults when faced with infinitely
1809 self-recursive reload() calls (as reported by bug #742342).
1810

Georg Brandl3ee81df2008-05-17 18:14:43 +00001814- Patch #1491866: change the complex() constructor to allow
1815 parthensized forms. This means complex(repr(x)) now works instead of
1816 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00001817
Georg Brandlaa2321b2007-03-07 00:40:28 +00001818- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00001819 makes the filenames the warning module prints much more sensible
1820 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00001821
Georg Brandl49aafc92007-03-07 00:34:46 +00001822- Variant of patch #697613: don't exit the interpreter on a SystemExit
1823 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00001824 variable is given, but break into the interactive interpreter just
1825 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00001833- Patch #1674228: when assigning a slice (old-style), check for the
1834 sq_ass_slice instead of the sq_slice slot.
1835
Georg Brandl3ee81df2008-05-17 18:14:43 +00001836- When printing an unraisable error, don't print exceptions. before
1837 the name. This duplicates the behavior whening normally printing
1838 exceptions.

1847 created a weakref on itself during a __del__ call for new-style
1848 classes (classic classes still have the bug).

1895
Armin Rigo7ccbca92006-10-04 12:17:45 +00001896- A number of places, including integer negation and absolute value,

Neal Norwitzdac090d2006-09-05 03:53:08 +00001938- Bug #1520864: unpacking singleton tuples in list comprehensions and
Georg Brandl3ee81df2008-05-17 18:14:43 +00001939 generator expressions (x for x, in ... ) works again. Fixing this
1940 problem required changing the .pyc magic number. This means that

2467 exception.

2680 partial fix for Bug #1574584.
2681
Georg Brandl3ee81df2008-05-17 18:14:43 +00002682- Fix turtle so that time.sleep is imported for the entire library.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002748- Issue #829951: In the smtplib module, SMTP.starttls() now complies
2749 with RFC 3207 and forgets any knowledge obtained from the server not
2750 obtained from the TLS negotiation itself. Patch contributed by Bill
2751 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00002752
Georg Brandl3ee81df2008-05-17 18:14:43 +00002753- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00002754 that the SMTP.starttls() caller no longer needs to call ehlo()
2755 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00002756 does not claim to support starttls. Adds the
2757 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill

2838 complex, tuple, list, dict, set, and frozenset. Formerly, it would
2839 silently miscode subclasses of those types. Now, it raises a

Georg Brandl3ee81df2008-05-17 18:14:43 +00002856 time so that opening a database previously created with the DB_DUP
2857 or DB_DUPSORT flag set will keep the proper behavior on subsequent
2858 opens. Specifically: dictionary assignment to a DB object will
2859 replace all values for a given key when the database allows
2860 duplicate values. DB users should use DB.put(k, v) when they want
2861 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00002862

2868 characters with ASCII value less than 32. Also, it correctly quotes
2869 dots only if they occur on a single line, as opposed to the previous
2870 behavior of quoting dots if they are the second character of any
2871 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00002872

3194-----
3195
Georg Brandl3ee81df2008-05-17 18:14:43 +00003196- Unified naming convention for free lists and their limits. All free
3197 lists in Object/ are named ``free_list``, the counter ``numfree``
3198 and the upper limit is a macro ``PyName_MAXFREELIST`` inside an
3199 #ifndef block.
Christian Heimes5b970ad2008-02-06 13:33:44 +00003200
Georg Brandl3ee81df2008-05-17 18:14:43 +00003201- ``PySet_Add()`` can now modify a newly created frozenset. Similarly
3202 to ``PyTuple_SetItem``, it can be used to populate a brand new
3203 frozenset; but it does not steal a reference to the added item.
Amaury Forgeot d'Arccab3d982008-02-03 22:51:43 +00003204
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003205- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003207- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format
3208 and _FormatV from Python 3.0. Made PyLong_AsSsize_t and
3209 PyLong_FromSsize_t public functions.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003210
3211- Patch #1720595: add T_BOOL to the range of structmember types.
3212
3213- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
3214 ``PyFloat_GetInfo()`` to the float API.
3215
Georg Brandl3ee81df2008-05-17 18:14:43 +00003216- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t#
3217 of w# format code incorrectly truncated the length to an int, even
3218 when PY_SSIZE_T_CLEAN is set. The str.decode method used to return
3219 incorrect results with huge strings.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003220
Georg Brandl3ee81df2008-05-17 18:14:43 +00003221- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE,
3222 Py_TYPE and Py_REFCNT.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003224- PEP 3123: Provide forward compatibility with Python 3.0, while
3225 keeping backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size,
3226 and PyVarObject_HEAD_INIT.

3229 defined.
Georg Brandl6caad7d2008-01-26 14:19:22 +00003230
3231- Patch #1733960: Allow T_LONGLONG to accept ints.

3238
3239- Fix some leftovers from the conversion from int to Py_ssize_t
3240 (relevant to strings and sequences of more than 2**31 items).
3241
3242- Make _PyGILState_NoteThreadState() static, it was not used anywhere
3243 outside of pystate.c and should not be necessary.
3244
Georg Brandl3ee81df2008-05-17 18:14:43 +00003245- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do
3246 absolute imports. In earlier versions they might have used relative
3247 imports under some conditions.
Christian Heimes000a0742008-01-03 22:16:32 +00003248
Georg Brandl3ee81df2008-05-17 18:14:43 +00003249- Added case insensitive comparison methods ``PyOS_stricmp(char*,
3250 char*)`` and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
Christian Heimes000a0742008-01-03 22:16:32 +00003251
Georg Brandl3ee81df2008-05-17 18:14:43 +00003252- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx

Georg Brandl3ee81df2008-05-17 18:14:43 +00003259- Patch #1706: Drop support for Win9x, WinME and NT4. Python now
3260 requires Windows 2000 or greater. The _WINVER and NTDDI_VERSION
3261 macros are set to Win2k for x86/32bit builds and WinXP for AMD64
3262 builds.
Christian Heimes95d64472008-02-09 19:55:22 +00003263

Georg Brandl3ee81df2008-05-17 18:14:43 +00003277- Removed the macfs module. It had been deprecated since Python 2.5.
3278 This lead to the deprecation of macostools.touched() as it relied
3279 solely on macfs and was a no-op under OS X.
