Raymond Hettinger20397532010-09-12 02:11:45 +0000548- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
549 This prevents user-created self-referencing ordered dictionaries from
550 becoming permanently uncollectable GC garbage. The downside is that
551 removing __del__ means that the internal doubly-linked list has to wait for
552 GC collection rather than freeing memory immediately when the refcnt drops
553 to zero.

562 original error is re-raised.

Ezio Melottiab2eb0e2010-06-05 19:21:32 +00001012- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
1013 start byte and the continuation byte(s) are now considered invalid, instead
1014 of the number of bytes specified by the start byte.
1015 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
1016 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
1017 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00001026- Issue #8748: Fix two issues with comparisons between complex and integer
1027 objects. (1) The comparison could incorrectly return True in some cases
1028 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
1029 (2) The comparison raised an OverflowError for large integers, leading

Georg Brandlba83f822010-03-14 09:50:54 +00001911 file position when calling `truncate()`. It would previously change the file
1912 position to the given argument, which goes against the tradition of

2015
Mark Dickinson1b34d252010-01-01 17:27:30 +00002016- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00002017 DeprecationWarning when passed a float argument where an integer was expected.

2134 ``PyArg_ParseTupleAndKeywords()``, ``PyArg_VaParse()``,
2135 ``PyArg_VaParseTupleAndKeywords()`` and ``PyArg_Parse()`` no longer accept
2136 float arguments for integer format codes (other than 'L'): previously an
2137 attempt to pass a float resulted in a DeprecationWarning; now it gives a
2138 TypeError. For the 'L' format code (which previously had no warning) there is
2139 now a DeprecationWarning.

2188 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002189

Georg Brandlba83f822010-03-14 09:50:54 +00002204- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2205 decimal string that's guaranteed to round back to x under correct rounding
2206 (with round-half-to-even rounding mode). Previously it gave a string based on
2207 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2208 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2209 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002210
Georg Brandlba83f822010-03-14 09:50:54 +00002211- Issue #7117: On almost all platforms: float-to-string and string-to-float
2212 conversions within Python are now correctly rounded. Places these conversions
2213 occur include: str for floats and complex numbers; the float and complex
2214 constructors; old-style and new-style numeric formatting; serialization and
2215 deserialization of floats and complex numbers using marshal, pickle and json;
2216 parsing of float and imaginary literals in Python code; Decimal-to-float
2217 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002218
Georg Brandlba83f822010-03-14 09:50:54 +00002219 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2220 providing correctly-rounded strtod and dtoa C functions. This code is
2221 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2222 the C compiler. There may be a small number of platforms on which correct
2223 operation of this code cannot be guaranteed, so the code is not used: notably,
2224 this applies to platforms where the C double format is not IEEE 754 binary64,
2225 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2226 and Python's configure script is unable to determine how to change the FPU
2227 precision. On these platforms conversions use the platform strtod and dtoa,
2228 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002229
Georg Brandlba83f822010-03-14 09:50:54 +00002230- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2231 uses the correctly-rounded string <-> float conversions described above (when
2232 available), and so produces correctly rounded results that will display nicely
2233 under the float repr. There are two related small changes: (1) round now
2234 accepts any class with an ``__index__()`` method for its second argument (but
2235 no longer accepts floats for the second argument), and (2) an excessively
2236 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2237 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002378- Issue #5981: Fix three minor inf/nan issues in float.fromhex:
Mark Dickinsonb1d45852009-05-11 15:33:08 +00002379
Georg Brandlba83f822010-03-14 09:50:54 +00002380 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2381 (2) parsing of strings representing infinities and nans was locale aware; and
2382 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002384- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2385 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2386 but with at least one decimal point and with a default precision
2387 of 12. Previously, the behavior the same but with a default precision of 6.
2388 This more closely matches ``str()``, and reduces surprises when adding
2389 alignment flags to the empty presentation type. This also affects the new
2390 complex.__format__ in the same way.
2391
2392- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by
2393 classtype's, even if it was None. property now inserts the __doc__ into the

Antoine Pitrouf8387af2009-03-23 18:41:45 +00002454- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00002455 untrackable objects are not tracked by the garbage collector. This can reduce
2456 the size of collections and therefore the garbage collection overhead on

2464 internal representation of integers, for performance reasons. Base 2**30 is
2465 enabled by default on 64-bit machines. Add --enable-big-digits option to
2466 configure, which overrides the default. Add sys.long_info structseq to

Georg Brandlba83f822010-03-14 09:50:54 +00002614- On windows, ``os.chdir()`` given unicode was not working if

2616 this code path is really executed because I cannot move to such directory on

Georg Brandlba83f822010-03-14 09:50:54 +00002619- Issue #4069: When ``set.remove(element)`` is used with a set element, the
2620 element is temporarily replaced with an equivalent frozenset. But the
2621 eventual KeyError would always report the empty ``frozenset()`` as the missing

Walter Dörwalded960ac2009-05-03 22:36:33 +00002642- Issue #5108: Handle %s like %S and %R in PyUnicode_FromFormatV(): Call
2643 PyUnicode_DecodeUTF8() once, remember the result and output it in a second
2644 step. This avoids problems with counting UTF-8 bytes that ignores the effect
2645 of using the replace error handler in PyUnicode_DecodeUTF8().
2646
Walter Dörwald726ba8e2009-05-06 14:32:35 +00002647- Issue #3739: The unicode-internal encoder now reports the number of characters

2649
Georg Brandlba83f822010-03-14 09:50:54 +00002650- Issue #2422: When compiled with the ``--with-valgrind`` option, the pymalloc
2651 allocator will be automatically disabled when running under Valgrind. This
2652 gives improved memory leak detection when running under Valgrind, while taking
2653 advantage of pymalloc at other times.

Georg Brandlba83f822010-03-14 09:50:54 +00003817 - If x is not an int, long or float, then packing x will always result in
3818 struct.error. Previously an x with an __int__ method could be packed by
3819 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
3820 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
3821 neither __int__ nor __long__, TypeError used to be raised (with a
3822 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
3823 struct.error in other cases.

3826 argument with an __int__ method can be packed, but use of this feature
3827 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00003876 leak-chasing test runs give sensible results. The previous method of reaping
3877 threads could return successfully while some Thread objects were still

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004018- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4019
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004020- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4021 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4022 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4023 ``printf`` function, whereas PyString_FromFormat has an independent
4024 implementation and uses "%zd" on all platforms for size_t values.
4025 This makes a difference on win64, where ``printf`` needs "%Id" to display
4026 64bit values.
4027
Benjamin Peterson97179b02008-09-09 20:55:01 +00004028- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4029 error.
4030
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004031- Issue #3777: long() applied to a float object now always return a long
4032 object; previously an int would be returned for small values. the __long__
4033 method is allowed to return either an int or a long, but the behaviour of
4034 float objects should not change to respect backward compatibility.
4035
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004036- Issue #3751: str.rpartition would perform a left-partition when called with
4037 a unicode argument.
4038
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004039- Issue #3683: Fix compilation when --without-threads is given.

Vinay Sajip35e3b032008-09-01 14:33:59 +00004042 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004043 was correctly parsed but parsing of subsequent arguments failed.
4044
Vinay Sajip35e3b032008-09-01 14:33:59 +00004045- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004046 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4047 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4048 when given a tuple of classes as second argument, were looking up
4049 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4050 type object.
4051
Neal Norwitz18aa3882008-08-24 05:04:52 +00004052- Fix crashes on memory allocation failure found with failmalloc.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004121 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4122 for catch_warnings() also led to an improvement in the raising of a
4123 DeprecationWarning related to warnings.warn_explicit().
4124

4195-----------------
4196
Guido van Rossumf8402962008-08-20 15:01:50 +00004197- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4198 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4199 extensions do not automatically benefit from the class attribute
4200 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4201 to their tp_flags field if they care. This is a backwards
4202 compatibility feature; in 3.0, all types will use the cache by
4203 default.
4204
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004205- Keyword arguments can now follow starred arguments. (``f(a, *args,
4206 keyword=23)`` is now valid syntax.)
4207
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004208- ctypes function pointers that are COM methods have a boolean True
4209 value again.
4210
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004211- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4212 by denying s# to parse objects that have a releasebuffer procedure,
4213 and introducing s*.
4214
Georg Brandl1e13ea92008-08-11 09:07:59 +00004215- Issue #3537: Fix an assertion failure when an empty but presized dict
4216 object was stored in the freelist.
4217
Mark Dickinsonb6467572008-08-04 21:30:09 +00004218- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4219 ValueError consistently across platforms.
4220
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004221- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4222 (64bit Unix, for example), unichr() would truncate its argument and return
4223 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4224
Neal Norwitze7d8be82008-07-31 17:17:14 +00004225- Apply security patches from Apple.
4226
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004227- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4228 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4229
Antoine Pitrou92f82162008-07-25 22:22:08 +00004230- Issue #1819: function calls with several named parameters are now on
4231 average 35% faster (as measured by pybench).
4232
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004233- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4234 the python debugger steps into a class statement: the free variables (local
4235 variables defined in an outer scope) would be deleted from the outer scope.
4236
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004237- Issue #2620: Overflow checking when allocating or reallocating memory
4238 was not always being done properly in some python types and extension
4239 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4240 all been updated to perform better checks and places in the code that
4241 would previously leak memory on the error path when such an allocation
4242 failed have been fixed.

4246
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004247- Issue #3612: Added some missing basic types in ctypes.wintypes.
4248
Benjamin Petersone977ad42008-08-20 01:42:01 +00004249- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4250 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4251
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004252- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4253 version reported by these tools does not necessarily follow the python
4254 version numbering scheme, so the module is less strict when parsing it.
4255
Nick Coghlanf70385a2008-08-18 12:42:46 +00004256- Issue #2235: Added Py3k warnings for types which will become unhashable
4257 under the stricter __hash__ inheritance rules in 3.0. Several types
4258 which did not meet the rules for hash invariants and were already
4259 unhashable in 3.0 have now been explicitly flagged as unhashable in
4260 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4261 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4262
Brett Cannon88f801d2008-08-18 00:46:22 +00004263- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things

4376
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004377- Issue #643841: The language reference now provides more detailed

4389-----------------
4390
Georg Brandl3e483f62008-07-16 22:57:41 +00004391- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4392 its methods now allow for items objects that can be converted to
4393 an integer using operator.index().
4394
Mark Dickinson64b7e502008-07-16 09:40:03 +00004395- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4396 produced a ValueError instead of giving the correct float.
4397
Eric Smitha5fa5a22008-07-16 00:11:49 +00004398- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4399 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4400
Mark Dickinson7103aa42008-07-15 19:08:33 +00004401- Issue #3008: the float type has a new instance method 'float.hex'
4402 and a new class method 'float.fromhex' to convert floating-point
4403 numbers to and from hexadecimal strings, respectively.
4404
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004405- Issue #2235: __hash__ is once again inherited by default. To allow
4406 collections.Hashable to remain meaningful in the presence of the
4407 default hash implementation (object.__hash__), it is now possible
4408 to explicit block inheritance of hash by setting __hash__=None at
4409 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4410 level.
4411
Nick Coghlanb028f502008-07-13 14:52:36 +00004412- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4413 the parent module cannot be found while performing an absolute import.
4414 This means that an incorrectly defined __package__ attribute will
4415 now only prevent relative imports in that module rather than causing
4416 all imports from that module to fail.
4417
Nick Coghlan14ff9942008-07-08 14:21:42 +00004418- Issue #2517: Allow unicode messages in Exceptions again by correctly

4428 another thread's dictionary.
4429
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004430- Issue #3004: Minor change to slice.indices(): the start and stop
4431 arguments are now treated identically, making the behaviour easier
4432 to describe and understand. For example, slice(None, -10,
4433 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4434 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4435 10, -1).
4436
Georg Brandl278fc502008-07-19 12:46:12 +00004437- Issue #3219: Calling a function with repeated keyword arguments,
4438 f(a=2, a=23), would not cause a syntax error. This was a regression
4439 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004477- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4478 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004479 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004480 content-length. The problem had been corrected in the 2.4 branch, but never

4888 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004889 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004890
4891 This is controlled by the configure argument ``--with-universal-archs``:
4892
4893 - ``--with-universal-archs=all``: install 4-way universal
4894
4895 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4896
4897 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4898
4899 This option should be used in combination with ``--enable-universalsdk=``.
4900
4901 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 +00004951- Issue #1631171: Re-implement the 'warnings' module in C (the
4952 original Python code has been kept as backup). This will allow for
4953 using the 'warning's machinery in such places as the parser where
4954 use of pure Python code is not possible. Both the ``showarning()``
4955 and ``formatwarning()`` gain an optional 'line' argument which is
4956 not called by default for backwards-compatibility reasons. Setting
4957 ``warnings.showwarning()`` to an implementation that lacks support
4958 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005021- Issue #2550: The approach used by client/server code for obtaining
5022 ports to listen on in network-oriented tests has been refined in an
5023 effort to facilitate running multiple instances of the entire
5024 regression test suite in parallel without issue.
5025 test_support.bind_port() has been fixed such that it will always
5026 return a unique port -- which wasn't always the case with the
5027 previous implementation, especially if socket options had been set
5028 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5029 new implementation of bind_port() will actually raise an exception
5030 if it is passed an AF_INET/SOCK_STREAM socket with either the
5031 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5032 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5033 the socket it's been passed. This currently only applies to
5034 Windows. This option prevents any other sockets from binding to the
5035 host/port we've bound to, thus removing the possibility of the
5036 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5037 when a second SOCK_STREAM socket binds and accepts to a host/port
5038 that's already been bound by another socket. The optional preferred
5039 port parameter to bind_port() has been removed. Under no
5040 circumstances should tests be hard coding ports!
5041
5042 test_support.find_unused_port() has also been introduced, which will
5043 pass a temporary socket object to bind_port() in order to obtain an
5044 unused port. The temporary socket object is then closed and
5045 deleted, and the port is returned. This method should only be used
5046 for obtaining an unused port in order to pass to an external program
5047 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5048 a parameter to a server-oriented class that doesn't give you direct
5049 access to the underlying socket used.
5050
5051 Finally, test_support.HOST has been introduced, which should be used
5052 for the host argument of any relevant socket calls (i.e. bind and
5053 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005054
5055 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005056 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005057 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5058 test_asynchat and test_socket_ssl.
5059
Georg Brandl3ee81df2008-05-17 18:14:43 +00005060 It is now possible for multiple instances of the regression test
5061 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005115- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005116 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5117 Plane. This affected raw unicode literals and the
5118 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5119 this case, like normal unicode literals and the 'unicode-escape'
5120 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005340- Added the future_builtins module, which contains hex() and oct().
5341 These are the PEP 3127 version of these functions, designed to be
5342 compatible with the hex() and oct() builtins from Python 3.0. They
5343 differ slightly in their output formats from the existing, unchanged
5344 Python 2.6 builtins. The expected usage of the future_builtins
5345 module is:
5346 from future_builtins import hex, oct
5347
Eric Smith7ef40bf2008-02-20 23:34:22 +00005348- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5349 exponents for exponents with absolute value < 100. Follows C99
5350 standard. This is a change on Windows, which would use 3 digits.
5351 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5352 so that any alterations it does to the resulting string will be
5353 available in stringlib/formatter.h (for float.__format__).
5354
Eric Smith5a3c1352008-02-19 13:21:56 +00005355- Implemented PEP 3101, Advanced String Formatting. This adds a new
5356 builtin format(); a format() method for str and unicode; a
5357 __format__() method to object, str, unicode, int, long, float, and
5358 datetime; the class string.Formatter; and the C API
5359 PyObject_Format().
5360
Georg Brandl3ee81df2008-05-17 18:14:43 +00005361- Fixed several potential crashes, all caused by specially crafted
5362 __del__ methods exploiting objects in temporarily inconsistent
5363 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005364
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005365- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005366 prevent a possible crash: an Abstract Base Class would try to access
5367 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005368

Georg Brandl3ee81df2008-05-17 18:14:43 +00005372- Clear all free lists during a gc.collect() of the highest generation
5373 in order to allow pymalloc to free more arenas. Python may give back
5374 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005375
Georg Brandl3ee81df2008-05-17 18:14:43 +00005376- Issue #2045: Fix an infinite recursion triggered when printing a

Georg Brandl3ee81df2008-05-17 18:14:43 +00005406- Patch #1473257: generator objects gain a gi_code attribute. This is
5407 the same object as the func_code attribute of the function that
5408 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005409
Georg Brandl3ee81df2008-05-17 18:14:43 +00005410- Issue #1920: "while 0" statements were completely removed by the
5411 compiler, even in the presence of an "else" clause, which is
5412 supposed to be run when the condition is false. Now the compiler
5413 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005414
Guido van Rossumeead05f2008-01-24 18:21:02 +00005415- A few crashers fixed: weakref_in_del.py (issue #1377858);

5422
Georg Brandl3ee81df2008-05-17 18:14:43 +00005423- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005424 several extension methods and modules do not work without unicode
5425 support.
5426

5431
Georg Brandl6caad7d2008-01-26 14:19:22 +00005432- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005433 added.
5434
Christian Heimesc94e2b52008-01-14 04:13:37 +00005435- sys.float_info / PyFloat_GetInfo: The floating point information
5436 object was converted from a dict to a specialized structseq object.
5437
Georg Brandl3ee81df2008-05-17 18:14:43 +00005438- Patch #1816: Added sys.flags structseq. It exposes the status of
5439 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005440
Georg Brandl3ee81df2008-05-17 18:14:43 +00005441- Objects/structseq.c: Implemented new structseq representation. The
5442 patch makes structseqs (e.g. the return value of os.stat) more
5443 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005444
Georg Brandl3ee81df2008-05-17 18:14:43 +00005445- Patch #1700288: added a type attribute cache that caches method
5446 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005447
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005448- Bug #1776: __import__() no longer accepts filenames on any platform.

5454 envvar and sys.dont_write_bytecode attribute. All these can be set
5455 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005456
Georg Brandl3ee81df2008-05-17 18:14:43 +00005457- Improve some exception messages when Windows fails to load an
5458 extension module. Now we get for example '%1 is not a valid Win32
5459 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005466- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005467 and INF. float("nan"), float("inf") and float("-inf") now work on
5468 every platform with IEEE 754 semantics.

5516
Georg Brandl21e99f42010-03-07 15:23:59 +00005517- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005518 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5519 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005520
Georg Brandl3ee81df2008-05-17 18:14:43 +00005521- Issue #1686386: Tuple's tp_repr did not take into account the
5522 possibility of having a self-referential tuple, which is possible
5523 from C code. Nor did object's tp_str consider that a type's tp_str
5524 could do something that could lead to an inifinite recursion.
5525 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5526 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005527

5529 'print' statement to write to a file since the GIL was not released
5530 as needed. Now PyObject_Print() does the right thing along with
5531 various tp_print implementations of the built-in types and those in
5532 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005533

Georg Brandl3ee81df2008-05-17 18:14:43 +00005542 PyObject_Call() never calling back out to Python code to trigger
5543 recursion depth updates/checks. Required the creation of a static
5544 RuntimeError instance in case normalizing an exception put the
5545 recursion check value past its limit. Fixes crashers

Guido van Rossum143b5642007-03-23 04:58:42 +00005594- Bug #1683368: The object.__init__() and object.__new__() methods are
5595 now stricter in rejecting excess arguments. The only time when
5596 either allows excess arguments is when it is not overridden and the
5597 other one is. For backwards compatibility, when both are
5598 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005599 warning later). Also, type.__init__() insists on the same signature
5600 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005602- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5603 object to complex using its __complex__() method before falling back
5604 to the __float__() method. Therefore, the functions in the cmath
5605 module now can operate on objects that define a __complex__()
5606 method.

Georg Brandl7b9c5552007-03-12 14:30:05 +00005624- Bug #1678647: write a newline after printing an exception in any
5625 case, even when converting the value to a string failed.
5626
Georg Brandl871f1bc2007-03-12 13:17:36 +00005627- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005628 its argument, if it exists. If not, it will work like before. This
5629 allows customizing the output of dir() in the presence of a
5630 __getattr__().

5640 raising a ValueError.

Georg Brandlaa2321b2007-03-07 00:40:28 +00005642- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005643 makes the filenames the warning module prints much more sensible
5644 when a PYTHONSTARTUP file is used.

5658 sq_ass_slice instead of the sq_slice slot.
5659
Georg Brandl3ee81df2008-05-17 18:14:43 +00005660- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00005712- Bug #1545497: when given an explicit base, int() did ignore NULs
5713 embedded in the string to convert.
5714
Georg Brandl846f73a2006-10-08 07:11:54 +00005715- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00005763 generator expressions (x for x, in ... ) works again. Fixing this
5764 problem required changing the .pyc magic number. This means that
5765 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006568- The implementation of UnicodeError objects has been simplified
6569 (start and end attributes are now stored directly as Py_ssize_t
6570 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00006571
Georg Brandl3ee81df2008-05-17 18:14:43 +00006572- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6573 with RFC 3207 and forgets any knowledge obtained from the server not
6574 obtained from the TLS negotiation itself. Patch contributed by Bill
6575 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006576
Georg Brandl3ee81df2008-05-17 18:14:43 +00006577- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006578 that the SMTP.starttls() caller no longer needs to call ehlo()
6579 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006580 does not claim to support starttls. Adds the
6581 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6582 Fenner.

6651 contents before adding elements from the iterable. This fix brings
6652 the behavior into line with that for list.__init__().
Raymond Hettingeradf9ffd2007-12-13 00:08:37 +00006653
Georg Brandl3ee81df2008-05-17 18:14:43 +00006654- Added wide char functions to msvcrt module: getwch, getwche, putwch

Georg Brandl3ee81df2008-05-17 18:14:43 +00006661- Marshal.dumps() now expects exact type matches for int, long, float,
6662 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6663 silently miscode subclasses of those types. Now, it raises a
6664 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006665

Georg Brandl3ee81df2008-05-17 18:14:43 +00006680 time so that opening a database previously created with the DB_DUP
6681 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6682 opens. Specifically: dictionary assignment to a DB object will
6683 replace all values for a given key when the database allows
6684 duplicate values. DB users should use DB.put(k, v) when they want
6685 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006686

6692 characters with ASCII value less than 32. Also, it correctly quotes
6693 dots only if they occur on a single line, as opposed to the previous
6694 behavior of quoting dots if they are the second character of any
6695 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006696

Georg Brandl3ee81df2008-05-17 18:14:43 +00007101- Removed the macfs module. It had been deprecated since Python 2.5.
7102 This lead to the deprecation of macostools.touched() as it relied
7103 solely on macfs and was a no-op under OS X.
