Martin v. Löwis9fa5a282008-09-11 06:53:30 +0000115- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
116
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +0000117- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
118 PyString_FromFormat or PyErr_Format to display size_t values. The macro
119 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
120 ``printf`` function, whereas PyString_FromFormat has an independent
121 implementation and uses "%zd" on all platforms for size_t values.
122 This makes a difference on win64, where ``printf`` needs "%Id" to display
123 64bit values.
124
Benjamin Peterson97179b02008-09-09 20:55:01 +0000125- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
126 error.

129 object; previously an int would be returned for small values. the __long__
130 method is allowed to return either an int or a long, but the behaviour of
131 float objects should not change to respect backward compatibility.
132
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +0000133- Issue #3751: str.rpartition would perform a left-partition when called with
134 a unicode argument.

Benjamin Peterson17f03ca2008-09-01 14:18:30 +0000136- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +0000139 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +0000140 was correctly parsed but parsing of subsequent arguments failed.
141
Vinay Sajip35e3b032008-09-01 14:33:59 +0000142- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +0000143 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
144 mechanism. In the process, fix a bug where isinstance() and issubclass(),
145 when given a tuple of classes as second argument, were looking up
146 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
147 type object.
148
Neal Norwitz18aa3882008-08-24 05:04:52 +0000149- Fix crashes on memory allocation failure found with failmalloc.

151- Fix memory leaks found with valgrind and update suppressions file.
152
153- Fix compiler warnings in opt mode which would lead to invalid memory reads.

Christian Heimes7d4c3172008-08-22 19:47:25 +0000157- Silenced another compiler warning about a used but not defined
158 function 'stringlib_contains_obj'.

288Core and Builtins
289-----------------
290
Guido van Rossumf8402962008-08-20 15:01:50 +0000291- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
292 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
293 extensions do not automatically benefit from the class attribute
294 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
295 to their tp_flags field if they care. This is a backwards
296 compatibility feature; in 3.0, all types will use the cache by
297 default.
298
Benjamin Petersonf647dc12008-08-20 01:27:30 +0000299- Keyword arguments can now follow starred arguments. (``f(a, *args,
300 keyword=23)`` is now valid syntax.)
301
Thomas Heller0ad5ae02008-08-19 19:25:04 +0000302- ctypes function pointers that are COM methods have a boolean True
303 value again.

310 object was stored in the freelist.
311
Mark Dickinsonb6467572008-08-04 21:30:09 +0000312- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
313 ValueError consistently across platforms.
314
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +0000315- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
316 (64bit Unix, for example), unichr() would truncate its argument and return
317 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
318
Neal Norwitze7d8be82008-07-31 17:17:14 +0000319- Apply security patches from Apple.
320
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +0000321- Issue #2542: Now that issubclass() may call arbitrary code, ensure that

Antoine Pitrou92f82162008-07-25 22:22:08 +0000324- Issue #1819: function calls with several named parameters are now on
325 average 35% faster (as measured by pybench).
326
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +0000327- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
328 the python debugger steps into a class statement: the free variables (local
329 variables defined in an outer scope) would be deleted from the outer scope.
330
Gregory P. Smith0470bab2008-07-22 04:46:32 +0000331- Issue #2620: Overflow checking when allocating or reallocating memory
332 was not always being done properly in some python types and extension
333 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
334 all been updated to perform better checks and places in the code that
335 would previously leak memory on the error path when such an allocation
336 failed have been fixed.

345
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +0000346- Issue #2234: distutils failed for some versions of the cygwin compiler. The
347 version reported by these tools does not necessarily follow the python
348 version numbering scheme, so the module is less strict when parsing it.
349
Nick Coghlanf70385a2008-08-18 12:42:46 +0000350- Issue #2235: Added Py3k warnings for types which will become unhashable
351 under the stricter __hash__ inheritance rules in 3.0. Several types
352 which did not meet the rules for hash invariants and were already
353 unhashable in 3.0 have now been explicitly flagged as unhashable in
354 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
355 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
356
Brett Cannon88f801d2008-08-18 00:46:22 +0000357- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

382 pathological input because of quadratic or exponential behaviour of a
383 regular expression.

386 thread-safe.
387
Brett Cannonbf3157b2008-08-14 05:00:03 +0000388- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
389 since mimetools itself is deprecated. Because modules are cached, all
390 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
391

399
Antoine Pitrou76b8bee2008-08-09 17:27:23 +0000400- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
401 a MemoryError rather than silently stop the iteration.
402
Guido van Rossum59ce9012008-08-09 14:55:34 +0000403- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
404 to _sre.compile() will now be rejected. This should not affect anybody
405 since the re.compile() function never generates invalid re-bytecode.
406
Skip Montanaroa032bf42008-08-08 22:52:51 +0000407- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
408 upon first access it can be automatically initialized from the csv file if
409 it wasn't initialized during instantiation.
410
Brett Cannon3aa2a492008-08-06 22:28:09 +0000411- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
412 the reload() built-in has been removed.

Antoine Pitroude781a42008-08-09 12:43:23 +0000426 asking for a specific length. This problem only affected files opened
427 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +0000428

453 file name rather than a ZipInfo instance, so files are extracted with
454 mode 0600 rather than 000 under Unix.
455
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +0000456- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

478================================
479
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +0000480*Release date: 17-Jul-2008*
481
Raymond Hettingere3ae6552008-06-20 04:18:15 +0000482Core and Builtins
483-----------------
484
Georg Brandl3e483f62008-07-16 22:57:41 +0000485- Issue #3156: Fix inconsistent behavior of the bytearray type: all
486 its methods now allow for items objects that can be converted to
487 an integer using operator.index().
488
Mark Dickinson64b7e502008-07-16 09:40:03 +0000489- Issue #3360: Fix incorrect parsing of '020000000000.0', which
490 produced a ValueError instead of giving the correct float.
491
Eric Smitha5fa5a22008-07-16 00:11:49 +0000492- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
493 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
494
Mark Dickinson7103aa42008-07-15 19:08:33 +0000495- Issue #3008: the float type has a new instance method 'float.hex'
496 and a new class method 'float.fromhex' to convert floating-point
497 numbers to and from hexadecimal strings, respectively.
498
Nick Coghlan6d6bd442008-07-15 15:40:22 +0000499- Issue #2235: __hash__ is once again inherited by default. To allow
500 collections.Hashable to remain meaningful in the presence of the
501 default hash implementation (object.__hash__), it is now possible
502 to explicit block inheritance of hash by setting __hash__=None at
503 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
504 level.
505
Nick Coghlanb028f502008-07-13 14:52:36 +0000506- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
507 the parent module cannot be found while performing an absolute import.
508 This means that an incorrectly defined __package__ attribute will
509 now only prevent relative imports in that module rather than causing
510 all imports from that module to fail.
511
Nick Coghlan14ff9942008-07-08 14:21:42 +0000512- Issue #2517: Allow unicode messages in Exceptions again by correctly
513 bypassing the instance dictionary when looking up __unicode__ on
514 new-style classes.
515
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +0000516- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
517 set to a custom object whose write() method happens to install
518 another file in sys.stdout.
519
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +0000520- Issue #3088: Corrected a race condition in classes derived from
521 threading.local: the first member set by a thread could be saved in
522 another thread's dictionary.
523
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +0000524- Issue #3004: Minor change to slice.indices(): the start and stop
525 arguments are now treated identically, making the behaviour easier
526 to describe and understand. For example, slice(None, -10,
527 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
528 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
529 10, -1).
530
Georg Brandl278fc502008-07-19 12:46:12 +0000531- Issue #3219: Calling a function with repeated keyword arguments,
532 f(a=2, a=23), would not cause a syntax error. This was a regression
533 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +0000534
Georg Brandl278fc502008-07-19 12:46:12 +0000535- Issue #2862: Make int and float freelist management consistent with
536 other freelists. Changes their CompactFreeList apis into
537 ClearFreeList apis and calls them via gc.collect().
Gregory P. Smith2fe77062008-07-06 03:35:58 +0000538

540-------
541
Thomas Heller57adf222008-08-14 19:10:48 +0000542- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
543 api functions without holding the GIL, which could lead to a fatal
544 error when they failed.
545
Martin v. Löwisaabf4042008-08-02 07:20:25 +0000546- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

555 ForkingPickler.register() to resolve conflict with ctypes.
556
Vinay Sajip51e65192008-07-18 09:01:10 +0000557- Issue #3090: Fixed ARCHFLAGS parsing on OS/X
Jesse Noller13e9d582008-07-16 14:32:36 +0000558
Thomas Heller880f5292008-07-15 19:39:38 +0000559- Issue #3313: Fixed a crash when a failed dlopen() call does not set
560 a valid dlerror() message.
561
Thomas Heller2bad6572008-07-15 17:19:50 +0000562- Issue #3258: Fixed a crash when a ctypes POINTER type to an
563 incomplete structure was created.
564

Raymond Hettinger3cd1e422008-07-10 14:03:19 +0000570
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000571- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
572 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000573 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +0000574 content-length. The problem had been corrected in the 2.4 branch, but never
575 merged into trunk.
576
Georg Brandle78fbcc2008-07-05 10:13:36 +0000577- Issue #2663: add filtering capability to shutil.copytree().

Vinay Sajip51e65192008-07-18 09:01:10 +0000587- Issue #449227: The rlcompleter module now adds "(" to callable objects
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +0000588 when completed.
Facundo Batista66c52772008-07-02 16:52:55 +0000589
Nick Coghlanc060b0e2008-07-02 13:09:19 +0000590- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
591 handling is now the same as that of other special attributes like __name__).
592
Brett Cannon8bb8fa52008-07-02 01:57:08 +0000593- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for
594 removal in Python 3.0 in favor of urllib2.urlopen().

605 default https port (443).
606
Gregory P. Smithdb3409c2008-07-17 03:13:05 +0000607- Issue #874900: after an os.fork() call the threading module state is cleaned
608 up in the child process to prevent deadlock and report proper thread counts
609 if the new process uses the threading module.

982 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +0000983 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +0000984
985 This is controlled by the configure argument ``--with-universal-archs``:
986
987 - ``--with-universal-archs=all``: install 4-way universal
988
989 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
990
991 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
992
993 This option should be used in combination with ``--enable-universalsdk=``.
994
995 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 +00001045- Issue #1631171: Re-implement the 'warnings' module in C (the
1046 original Python code has been kept as backup). This will allow for
1047 using the 'warning's machinery in such places as the parser where
1048 use of pure Python code is not possible. Both the ``showarning()``
1049 and ``formatwarning()`` gain an optional 'line' argument which is
1050 not called by default for backwards-compatibility reasons. Setting
1051 ``warnings.showwarning()`` to an implementation that lacks support
1052 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001115- Issue #2550: The approach used by client/server code for obtaining
1116 ports to listen on in network-oriented tests has been refined in an
1117 effort to facilitate running multiple instances of the entire
1118 regression test suite in parallel without issue.
1119 test_support.bind_port() has been fixed such that it will always
1120 return a unique port -- which wasn't always the case with the
1121 previous implementation, especially if socket options had been set
1122 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
1123 new implementation of bind_port() will actually raise an exception
1124 if it is passed an AF_INET/SOCK_STREAM socket with either the
1125 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
1126 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
1127 the socket it's been passed. This currently only applies to
1128 Windows. This option prevents any other sockets from binding to the
1129 host/port we've bound to, thus removing the possibility of the
1130 'non-deterministic' behaviour, as Microsoft puts it, that occurs
1131 when a second SOCK_STREAM socket binds and accepts to a host/port
1132 that's already been bound by another socket. The optional preferred
1133 port parameter to bind_port() has been removed. Under no
1134 circumstances should tests be hard coding ports!
1135
1136 test_support.find_unused_port() has also been introduced, which will
1137 pass a temporary socket object to bind_port() in order to obtain an
1138 unused port. The temporary socket object is then closed and
1139 deleted, and the port is returned. This method should only be used
1140 for obtaining an unused port in order to pass to an external program
1141 (i.e. the -accept [port] argument to openssl's s_server mode) or as
1142 a parameter to a server-oriented class that doesn't give you direct
1143 access to the underlying socket used.
1144
1145 Finally, test_support.HOST has been introduced, which should be used
1146 for the host argument of any relevant socket calls (i.e. bind and
1147 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00001148
1149 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00001150 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00001151 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
1152 test_asynchat and test_socket_ssl.
1153
Georg Brandl3ee81df2008-05-17 18:14:43 +00001154 It is now possible for multiple instances of the regression test
1155 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00001209- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00001210 \Uxxxxxxxx did not accept values outside the Basic Multilingual
1211 Plane. This affected raw unicode literals and the
1212 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
1213 this case, like normal unicode literals and the 'unicode-escape'
1214 codec.

Facundo Batistafc2d0102008-02-23 12:01:13 +00001432 issue 215555 for a discussion.
1433
Eric Smitha73fbe72008-02-23 03:09:44 +00001434- Added the future_builtins module, which contains hex() and oct().
1435 These are the PEP 3127 version of these functions, designed to be
1436 compatible with the hex() and oct() builtins from Python 3.0. They
1437 differ slightly in their output formats from the existing, unchanged
1438 Python 2.6 builtins. The expected usage of the future_builtins
1439 module is:

1441
Eric Smith7ef40bf2008-02-20 23:34:22 +00001442- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
1443 exponents for exponents with absolute value < 100. Follows C99
1444 standard. This is a change on Windows, which would use 3 digits.
1445 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
1446 so that any alterations it does to the resulting string will be
1447 available in stringlib/formatter.h (for float.__format__).
1448
Eric Smith5a3c1352008-02-19 13:21:56 +00001449- Implemented PEP 3101, Advanced String Formatting. This adds a new
1450 builtin format(); a format() method for str and unicode; a
1451 __format__() method to object, str, unicode, int, long, float, and
1452 datetime; the class string.Formatter; and the C API
1453 PyObject_Format().
1454
Georg Brandl3ee81df2008-05-17 18:14:43 +00001455- Fixed several potential crashes, all caused by specially crafted
1456 __del__ methods exploiting objects in temporarily inconsistent
1457 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001466- Clear all free lists during a gc.collect() of the highest generation
1467 in order to allow pymalloc to free more arenas. Python may give back
1468 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00001469
Georg Brandl3ee81df2008-05-17 18:14:43 +00001470- Issue #2045: Fix an infinite recursion triggered when printing a

Christian Heimesf75dbef2008-02-08 00:11:31 +00001474- Fixed a minor memory leak in dictobject.c. The content of the free
1475 list was not freed on interpreter shutdown.
1476
Georg Brandl3ee81df2008-05-17 18:14:43 +00001477- Limit free list of method and builtin function objects to 256
1478 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00001479
Georg Brandl3ee81df2008-05-17 18:14:43 +00001480- Patch #1953: Added ``sys._compact_freelists()`` and the C API
1481 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00001482 to compact the internal free lists of pre-allocted ints and floats.
1483
Georg Brandl3ee81df2008-05-17 18:14:43 +00001484- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
1485 calls. Python expected the return type int but the fork familie
1486 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001500- Patch #1473257: generator objects gain a gi_code attribute. This is
1501 the same object as the func_code attribute of the function that
1502 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00001503
Georg Brandl3ee81df2008-05-17 18:14:43 +00001504- Issue #1920: "while 0" statements were completely removed by the
1505 compiler, even in the presence of an "else" clause, which is
1506 supposed to be run when the condition is false. Now the compiler
1507 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00001508
Guido van Rossumeead05f2008-01-24 18:21:02 +00001509- A few crashers fixed: weakref_in_del.py (issue #1377858);
1510 loosing_dict_ref.py (issue #1303614, test67.py);
1511 borrowed_ref_[34].py (not in tracker).
1512
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00001513- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00001514 suppressed while an extension is loaded by calling SetErrorMode in

1516
Georg Brandl3ee81df2008-05-17 18:14:43 +00001517- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00001518 several extension methods and modules do not work without unicode
1519 support.
1520
Georg Brandl26543b12008-01-21 18:36:51 +00001521- Issue #1882: when compiling code from a string, encoding cookies in the

1523
Georg Brandl14404b62008-01-19 19:27:05 +00001524- Issue #1679: "0x" was taken as a valid integer literal.
1525
Georg Brandl6caad7d2008-01-26 14:19:22 +00001526- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00001527 added.
1528
Christian Heimesc94e2b52008-01-14 04:13:37 +00001529- sys.float_info / PyFloat_GetInfo: The floating point information
1530 object was converted from a dict to a specialized structseq object.
1531
Georg Brandl3ee81df2008-05-17 18:14:43 +00001532- Patch #1816: Added sys.flags structseq. It exposes the status of
1533 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00001534
Georg Brandl3ee81df2008-05-17 18:14:43 +00001535- Objects/structseq.c: Implemented new structseq representation. The
1536 patch makes structseqs (e.g. the return value of os.stat) more
1537 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00001538
Georg Brandl3ee81df2008-05-17 18:14:43 +00001539- Patch #1700288: added a type attribute cache that caches method
1540 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00001541
Neal Norwitz3fc15b82008-01-10 05:42:58 +00001542- Bug #1776: __import__() no longer accepts filenames on any platform.
1543 The first parameter to __import__() must be a valid module name.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001551- Improve some exception messages when Windows fails to load an
1552 extension module. Now we get for example '%1 is not a valid Win32
1553 application' instead of 'error code 193'.

Georg Brandl3ee81df2008-05-17 18:14:43 +00001611- The enumerate() builtin function is no longer bounded to sequences
1612 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
1613 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00001614
Georg Brandl3ee81df2008-05-17 18:14:43 +00001615- Issue #1686386: Tuple's tp_repr did not take into account the
1616 possibility of having a self-referential tuple, which is possible
1617 from C code. Nor did object's tp_str consider that a type's tp_str
1618 could do something that could lead to an inifinite recursion.
1619 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
1620 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00001621
Georg Brandl3ee81df2008-05-17 18:14:43 +00001622- Issue #1164: It was possible to trigger deadlock when using the
1623 'print' statement to write to a file since the GIL was not released
1624 as needed. Now PyObject_Print() does the right thing along with
1625 various tp_print implementations of the built-in types and those in
1626 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00001627

Georg Brandl3ee81df2008-05-17 18:14:43 +00001636 PyObject_Call() never calling back out to Python code to trigger
1637 recursion depth updates/checks. Required the creation of a static
1638 RuntimeError instance in case normalizing an exception put the
1639 recursion check value past its limit. Fixes crashers

1687
Guido van Rossum143b5642007-03-23 04:58:42 +00001688- Bug #1683368: The object.__init__() and object.__new__() methods are
1689 now stricter in rejecting excess arguments. The only time when
1690 either allows excess arguments is when it is not overridden and the
1691 other one is. For backwards compatibility, when both are
1692 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00001693 warning later). Also, type.__init__() insists on the same signature
1694 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00001696- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
1697 object to complex using its __complex__() method before falling back
1698 to the __float__() method. Therefore, the functions in the cmath
1699 module now can operate on objects that define a __complex__()
1700 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00001718- Bug #1678647: write a newline after printing an exception in any
1719 case, even when converting the value to a string failed.
1720
Georg Brandl871f1bc2007-03-12 13:17:36 +00001721- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00001722 its argument, if it exists. If not, it will work like before. This
1723 allows customizing the output of dir() in the presence of a
1724 __getattr__().

1734 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00001736- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00001737 makes the filenames the warning module prints much more sensible
1738 when a PYTHONSTARTUP file is used.

1752 sq_ass_slice instead of the sq_slice slot.
1753
Georg Brandl3ee81df2008-05-17 18:14:43 +00001754- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00001806- Bug #1545497: when given an explicit base, int() did ignore NULs
1807 embedded in the string to convert.
1808
Georg Brandl846f73a2006-10-08 07:11:54 +00001809- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00001857 generator expressions (x for x, in ... ) works again. Fixing this
1858 problem required changing the .pyc magic number. This means that
1859 .pyc files generated before 2.5c2 will be regenerated.

2262
Vinay Sajip8549ce32007-05-06 17:53:37 +00002263- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00002289 AttributeError instead of an IOError when the server's response

2381 TestCase and TestSuite subclasses (not instances) are no longer

2384 -- the failure just occurred later, with a more cumbersome
2385 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00002662- The implementation of UnicodeError objects has been simplified
2663 (start and end attributes are now stored directly as Py_ssize_t
2664 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00002665
Georg Brandl3ee81df2008-05-17 18:14:43 +00002666- Issue #829951: In the smtplib module, SMTP.starttls() now complies
2667 with RFC 3207 and forgets any knowledge obtained from the server not
2668 obtained from the TLS negotiation itself. Patch contributed by Bill
2669 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00002670
Georg Brandl3ee81df2008-05-17 18:14:43 +00002671- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00002672 that the SMTP.starttls() caller no longer needs to call ehlo()
2673 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00002674 does not claim to support starttls. Adds the
2675 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
2676 Fenner.

2756 complex, tuple, list, dict, set, and frozenset. Formerly, it would
2757 silently miscode subclasses of those types. Now, it raises a
2758 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00002759

Georg Brandl3ee81df2008-05-17 18:14:43 +00002774 time so that opening a database previously created with the DB_DUP
2775 or DB_DUPSORT flag set will keep the proper behavior on subsequent
2776 opens. Specifically: dictionary assignment to a DB object will
2777 replace all values for a given key when the database allows
2778 duplicate values. DB users should use DB.put(k, v) when they want
2779 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00002780

2786 characters with ASCII value less than 32. Also, it correctly quotes
2787 dots only if they occur on a single line, as opposed to the previous
2788 behavior of quoting dots if they are the second character of any
2789 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00002790
