Raymond Hettinger20397532010-09-12 02:11:45 +0000539- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
540 This prevents user-created self-referencing ordered dictionaries from
541 becoming permanently uncollectable GC garbage. The downside is that
542 removing __del__ means that the internal doubly-linked list has to wait for
543 GC collection rather than freeing memory immediately when the refcnt drops
544 to zero.
545
Raymond Hettingerffd2a422010-09-10 10:47:22 +0000546- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

549
Antoine Pitrouc818ed42010-09-07 21:40:25 +0000550- Issue #9792: In case of connection failure, socket.create_connection()

552 to fetch the original errno, or to filter timeout errors. Now the
553 original error is re-raised.
554
Antoine Pitrouf4f61712010-09-07 16:34:47 +0000555- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

576 character years even if the message contains RFC822 two character years.
577
Daniel Stutzbach91287322010-08-24 21:09:30 +0000578- Issue #8750: Fixed MutableSet's methods to correctly handle

1405 with a non-empty format string. This is an effort to future-proof user
1406 code. If a derived class does not currently implement __format__ but later
1407 adds its own __format__, it would most likely break user code that had

1483 makes Fraction <=> complex comparisons consistent with int <=> complex, float
1484 <=> complex, and complex <=> complex comparisons.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001901- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001902 file position when calling `truncate()`. It would previously change the file
1903 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001904 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

1907 class used to represent files stored inside an archive. The new
1908 implementation is significantly faster and can be wrapped in a
1909 ``io.BufferedReader`` object for more speedups. It also solves an issue
1910 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

2179 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00002180
Georg Brandlba83f822010-03-14 09:50:54 +00002181- Remove switch from "%f" formatting to "%g" formatting for floats larger than
2182 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00002195- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2196 decimal string that's guaranteed to round back to x under correct rounding
2197 (with round-half-to-even rounding mode). Previously it gave a string based on
2198 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2199 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2200 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002201
Georg Brandlba83f822010-03-14 09:50:54 +00002202- Issue #7117: On almost all platforms: float-to-string and string-to-float
2203 conversions within Python are now correctly rounded. Places these conversions
2204 occur include: str for floats and complex numbers; the float and complex
2205 constructors; old-style and new-style numeric formatting; serialization and
2206 deserialization of floats and complex numbers using marshal, pickle and json;
2207 parsing of float and imaginary literals in Python code; Decimal-to-float
2208 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002209
Georg Brandlba83f822010-03-14 09:50:54 +00002210 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2211 providing correctly-rounded strtod and dtoa C functions. This code is
2212 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2213 the C compiler. There may be a small number of platforms on which correct
2214 operation of this code cannot be guaranteed, so the code is not used: notably,
2215 this applies to platforms where the C double format is not IEEE 754 binary64,
2216 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2217 and Python's configure script is unable to determine how to change the FPU
2218 precision. On these platforms conversions use the platform strtod and dtoa,
2219 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002220
Georg Brandlba83f822010-03-14 09:50:54 +00002221- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2222 uses the correctly-rounded string <-> float conversions described above (when
2223 available), and so produces correctly rounded results that will display nicely
2224 under the float repr. There are two related small changes: (1) round now
2225 accepts any class with an ``__index__()`` method for its second argument (but
2226 no longer accepts floats for the second argument), and (2) an excessively
2227 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2228 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00002370
Georg Brandlba83f822010-03-14 09:50:54 +00002371 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
2372 (2) parsing of strings representing infinities and nans was locale aware; and
2373 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00002375- Issue #5920: For ``float.__format__()``, change the behavior with the empty
2376 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
2377 but with at least one decimal point and with a default precision
2378 of 12. Previously, the behavior the same but with a default precision of 6.
2379 This more closely matches ``str()``, and reduces surprises when adding
2380 alignment flags to the empty presentation type. This also affects the new
2381 complex.__format__ in the same way.
2382
2383- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

Georg Brandlba83f822010-03-14 09:50:54 +00003867 leak-chasing test runs give sensible results. The previous method of reaping
3868 threads could return successfully while some Thread objects were still
3869 referenced. This also introduces a new private function: ``thread._count()``.

Georg Brandl2bd92a52009-10-11 21:10:07 +00003989- Issue #3850: recursion tests in Tools/scripts/find_recursion_limit.py can raise
Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003990 AttributeError instead of RuntimeError, depending in which C API call
3991 exactly the recursion limit is exceeded. Consequently, both exception types
3992 are caught and silenced.

4008
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00004009- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
4010
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00004011- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
4012 PyString_FromFormat or PyErr_Format to display size_t values. The macro
4013 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
4014 ``printf`` function, whereas PyString_FromFormat has an independent
4015 implementation and uses "%zd" on all platforms for size_t values.
4016 This makes a difference on win64, where ``printf`` needs "%Id" to display
4017 64bit values.
4018
Benjamin Peterson97179b02008-09-09 20:55:01 +00004019- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
4020 error.
4021
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00004022- Issue #3777: long() applied to a float object now always return a long
4023 object; previously an int would be returned for small values. the __long__
4024 method is allowed to return either an int or a long, but the behaviour of
4025 float objects should not change to respect backward compatibility.
4026
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00004027- Issue #3751: str.rpartition would perform a left-partition when called with
4028 a unicode argument.
4029
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00004030- Issue #3683: Fix compilation when --without-threads is given.
4031
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004032- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00004033 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00004034 was correctly parsed but parsing of subsequent arguments failed.
4035
Vinay Sajip35e3b032008-09-01 14:33:59 +00004036- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00004037 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
4038 mechanism. In the process, fix a bug where isinstance() and issubclass(),
4039 when given a tuple of classes as second argument, were looking up
4040 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
4041 type object.
4042
Neal Norwitz18aa3882008-08-24 05:04:52 +00004043- Fix crashes on memory allocation failure found with failmalloc.
4044
4045- Fix memory leaks found with valgrind and update suppressions file.
4046
4047- Fix compiler warnings in opt mode which would lead to invalid memory reads.
4048
4049- Fix problem using wrong name in decimal module reported by pychecker.
4050
Christian Heimes7d4c3172008-08-22 19:47:25 +00004051- Silenced another compiler warning about a used but not defined
4052 function 'stringlib_contains_obj'.

4055 ``__delslice__``.
4056
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00004057- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
4058 library targets in the Makefile.
4059
Gregory P. Smith980b99b2008-09-07 05:15:18 +00004060- Issue #1204: The configure script now tests for additional libraries
4061 that may be required when linking against readline. This fixes issues
4062 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

4073 stack usage in the case of deeply nested objects.
4074

Nick Coghland2e09382008-09-11 12:11:06 +00004085- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00004086 return a list or None rather than a custom object.
4087
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00004088- Issue #1638033: Cookie.Morsel gained the httponly attribute.

Brett Cannon1eaf0742008-09-02 01:25:16 +00004112 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4113 for catch_warnings() also led to an improvement in the raising of a
4114 DeprecationWarning related to warnings.warn_explicit().
4115
Benjamin Peterson973e6c22008-09-01 23:12:58 +00004116- The deprecation warnings for the old camelCase threading API were removed.

Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00004139- Issue #2975: When compiling several extension modules with Visual Studio 2008
4140 from the same python interpreter, some environment variables would grow
4141 without limit.
4142
Benjamin Peterson37346b22008-08-23 20:27:43 +00004143- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
4144 exploitation of poor argument checking.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004184
4185Core and Builtins
4186-----------------
4187
Guido van Rossumf8402962008-08-20 15:01:50 +00004188- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4189 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4190 extensions do not automatically benefit from the class attribute
4191 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4192 to their tp_flags field if they care. This is a backwards
4193 compatibility feature; in 3.0, all types will use the cache by
4194 default.
4195
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004196- Keyword arguments can now follow starred arguments. (``f(a, *args,
4197 keyword=23)`` is now valid syntax.)
4198
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004199- ctypes function pointers that are COM methods have a boolean True
4200 value again.
4201
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004202- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4203 by denying s# to parse objects that have a releasebuffer procedure,
4204 and introducing s*.
4205
Georg Brandl1e13ea92008-08-11 09:07:59 +00004206- Issue #3537: Fix an assertion failure when an empty but presized dict
4207 object was stored in the freelist.
4208
Mark Dickinsonb6467572008-08-04 21:30:09 +00004209- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4210 ValueError consistently across platforms.
4211
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004212- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4213 (64bit Unix, for example), unichr() would truncate its argument and return
4214 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4215
Neal Norwitze7d8be82008-07-31 17:17:14 +00004216- Apply security patches from Apple.
4217
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004218- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4219 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4220
Antoine Pitrou92f82162008-07-25 22:22:08 +00004221- Issue #1819: function calls with several named parameters are now on
4222 average 35% faster (as measured by pybench).
4223
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004224- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4225 the python debugger steps into a class statement: the free variables (local
4226 variables defined in an outer scope) would be deleted from the outer scope.
4227
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004228- Issue #2620: Overflow checking when allocating or reallocating memory
4229 was not always being done properly in some python types and extension
4230 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4231 all been updated to perform better checks and places in the code that
4232 would previously leak memory on the error path when such an allocation
4233 failed have been fixed.

4237
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004238- Issue #3612: Added some missing basic types in ctypes.wintypes.
4239
Benjamin Petersone977ad42008-08-20 01:42:01 +00004240- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4241 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4242
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004243- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4244 version reported by these tools does not necessarily follow the python
4245 version numbering scheme, so the module is less strict when parsing it.
4246
Nick Coghlanf70385a2008-08-18 12:42:46 +00004247- Issue #2235: Added Py3k warnings for types which will become unhashable
4248 under the stricter __hash__ inheritance rules in 3.0. Several types
4249 which did not meet the rules for hash invariants and were already
4250 unhashable in 3.0 have now been explicitly flagged as unhashable in
4251 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4252 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4253
Brett Cannon88f801d2008-08-18 00:46:22 +00004254- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4255 imported into the module but exposed as part of the module's API.
4256
Brett Cannon7b96f072008-08-18 00:41:11 +00004257- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4258
Brett Cannon46225e72008-08-18 00:36:52 +00004259- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004261- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4262
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004263- Issue #3575: Incremental decoder's decode function now takes bytearray
4264 by using 's*' instead of 't#'.

4367
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00004368- Issue #643841: The language reference now provides more detailed

4380-----------------
4381
Georg Brandl3e483f62008-07-16 22:57:41 +00004382- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4383 its methods now allow for items objects that can be converted to
4384 an integer using operator.index().
4385
Mark Dickinson64b7e502008-07-16 09:40:03 +00004386- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4387 produced a ValueError instead of giving the correct float.
4388
Eric Smitha5fa5a22008-07-16 00:11:49 +00004389- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4390 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4391
Mark Dickinson7103aa42008-07-15 19:08:33 +00004392- Issue #3008: the float type has a new instance method 'float.hex'
4393 and a new class method 'float.fromhex' to convert floating-point
4394 numbers to and from hexadecimal strings, respectively.
4395
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004396- Issue #2235: __hash__ is once again inherited by default. To allow
4397 collections.Hashable to remain meaningful in the presence of the
4398 default hash implementation (object.__hash__), it is now possible
4399 to explicit block inheritance of hash by setting __hash__=None at
4400 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4401 level.
4402
Nick Coghlanb028f502008-07-13 14:52:36 +00004403- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4404 the parent module cannot be found while performing an absolute import.
4405 This means that an incorrectly defined __package__ attribute will
4406 now only prevent relative imports in that module rather than causing
4407 all imports from that module to fail.
4408
Nick Coghlan14ff9942008-07-08 14:21:42 +00004409- Issue #2517: Allow unicode messages in Exceptions again by correctly
4410 bypassing the instance dictionary when looking up __unicode__ on
4411 new-style classes.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004417- Issue #3088: Corrected a race condition in classes derived from
4418 threading.local: the first member set by a thread could be saved in
4419 another thread's dictionary.
4420
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004421- Issue #3004: Minor change to slice.indices(): the start and stop
4422 arguments are now treated identically, making the behaviour easier
4423 to describe and understand. For example, slice(None, -10,
4424 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4425 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4426 10, -1).
4427
Georg Brandl278fc502008-07-19 12:46:12 +00004428- Issue #3219: Calling a function with repeated keyword arguments,
4429 f(a=2, a=23), would not cause a syntax error. This was a regression
4430 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004431
Georg Brandl278fc502008-07-19 12:46:12 +00004432- Issue #2862: Make int and float freelist management consistent with
4433 other freelists. Changes their CompactFreeList apis into

4440 api functions without holding the GIL, which could lead to a fatal
4441 error when they failed.
4442
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004443- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004468- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4469 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004470 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004471 content-length. The problem had been corrected in the 2.4 branch, but never
4472 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004487- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

4831 suitable sign) if n is large and negative; previously, it raised
4832 OverflowError.

Ronald Oussoren5640ce22008-06-05 12:58:24 +00004878- On MacOS X it is now possible to install the framework in 64-bit
4879 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004880 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004881
4882 This is controlled by the configure argument ``--with-universal-archs``:
4883
4884 - ``--with-universal-archs=all``: install 4-way universal
4885
4886 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4887
4888 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4889
4890 This option should be used in combination with ``--enable-universalsdk=``.
4891
4892 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 +00004942- Issue #1631171: Re-implement the 'warnings' module in C (the
4943 original Python code has been kept as backup). This will allow for
4944 using the 'warning's machinery in such places as the parser where
4945 use of pure Python code is not possible. Both the ``showarning()``
4946 and ``formatwarning()`` gain an optional 'line' argument which is
4947 not called by default for backwards-compatibility reasons. Setting
4948 ``warnings.showwarning()`` to an implementation that lacks support
4949 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005012- Issue #2550: The approach used by client/server code for obtaining
5013 ports to listen on in network-oriented tests has been refined in an
5014 effort to facilitate running multiple instances of the entire
5015 regression test suite in parallel without issue.
5016 test_support.bind_port() has been fixed such that it will always
5017 return a unique port -- which wasn't always the case with the
5018 previous implementation, especially if socket options had been set
5019 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
5020 new implementation of bind_port() will actually raise an exception
5021 if it is passed an AF_INET/SOCK_STREAM socket with either the
5022 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
5023 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
5024 the socket it's been passed. This currently only applies to
5025 Windows. This option prevents any other sockets from binding to the
5026 host/port we've bound to, thus removing the possibility of the
5027 'non-deterministic' behaviour, as Microsoft puts it, that occurs
5028 when a second SOCK_STREAM socket binds and accepts to a host/port
5029 that's already been bound by another socket. The optional preferred
5030 port parameter to bind_port() has been removed. Under no
5031 circumstances should tests be hard coding ports!
5032
5033 test_support.find_unused_port() has also been introduced, which will
5034 pass a temporary socket object to bind_port() in order to obtain an
5035 unused port. The temporary socket object is then closed and
5036 deleted, and the port is returned. This method should only be used
5037 for obtaining an unused port in order to pass to an external program
5038 (i.e. the -accept [port] argument to openssl's s_server mode) or as
5039 a parameter to a server-oriented class that doesn't give you direct
5040 access to the underlying socket used.
5041
5042 Finally, test_support.HOST has been introduced, which should be used
5043 for the host argument of any relevant socket calls (i.e. bind and
5044 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00005045
5046 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00005047 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00005048 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
5049 test_asynchat and test_socket_ssl.
5050
Georg Brandl3ee81df2008-05-17 18:14:43 +00005051 It is now possible for multiple instances of the regression test
5052 suite to run in parallel without issue.

Amaury Forgeot d'Arc9a0d3462008-03-23 09:55:29 +00005106- Issue #1477: With narrow Unicode builds, the unicode escape sequence
Georg Brandl3ee81df2008-05-17 18:14:43 +00005107 \Uxxxxxxxx did not accept values outside the Basic Multilingual
5108 Plane. This affected raw unicode literals and the
5109 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
5110 this case, like normal unicode literals and the 'unicode-escape'
5111 codec.

Eric Smitha73fbe72008-02-23 03:09:44 +00005331- Added the future_builtins module, which contains hex() and oct().
5332 These are the PEP 3127 version of these functions, designed to be
5333 compatible with the hex() and oct() builtins from Python 3.0. They
5334 differ slightly in their output formats from the existing, unchanged
5335 Python 2.6 builtins. The expected usage of the future_builtins
5336 module is:
5337 from future_builtins import hex, oct
5338
Eric Smith7ef40bf2008-02-20 23:34:22 +00005339- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5340 exponents for exponents with absolute value < 100. Follows C99
5341 standard. This is a change on Windows, which would use 3 digits.
5342 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5343 so that any alterations it does to the resulting string will be
5344 available in stringlib/formatter.h (for float.__format__).
5345
Eric Smith5a3c1352008-02-19 13:21:56 +00005346- Implemented PEP 3101, Advanced String Formatting. This adds a new
5347 builtin format(); a format() method for str and unicode; a
5348 __format__() method to object, str, unicode, int, long, float, and
5349 datetime; the class string.Formatter; and the C API
5350 PyObject_Format().
5351
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352- Fixed several potential crashes, all caused by specially crafted
5353 __del__ methods exploiting objects in temporarily inconsistent
5354 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00005355
Vinay Sajipb7edfc42008-04-02 21:10:23 +00005356- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00005357 prevent a possible crash: an Abstract Base Class would try to access
5358 a slot on a registered virtual subclass.
Amaury Forgeot d'Arc60d6c7f2008-02-15 21:22:45 +00005359

Georg Brandl3ee81df2008-05-17 18:14:43 +00005363- Clear all free lists during a gc.collect() of the highest generation
5364 in order to allow pymalloc to free more arenas. Python may give back
5365 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005366
Georg Brandl3ee81df2008-05-17 18:14:43 +00005367- Issue #2045: Fix an infinite recursion triggered when printing a
5368 subclass of collections.defaultdict, if its default_factory is set
5369 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005370
Christian Heimesf75dbef2008-02-08 00:11:31 +00005371- Fixed a minor memory leak in dictobject.c. The content of the free
5372 list was not freed on interpreter shutdown.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005377- Patch #1953: Added ``sys._compact_freelists()`` and the C API
5378 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00005379 to compact the internal free lists of pre-allocted ints and floats.
5380
Georg Brandl3ee81df2008-05-17 18:14:43 +00005381- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
5382 calls. Python expected the return type int but the fork familie
5383 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005397- Patch #1473257: generator objects gain a gi_code attribute. This is
5398 the same object as the func_code attribute of the function that
5399 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005400
Georg Brandl3ee81df2008-05-17 18:14:43 +00005401- Issue #1920: "while 0" statements were completely removed by the
5402 compiler, even in the presence of an "else" clause, which is
5403 supposed to be run when the condition is false. Now the compiler
5404 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005405
Guido van Rossumeead05f2008-01-24 18:21:02 +00005406- A few crashers fixed: weakref_in_del.py (issue #1377858);
5407 loosing_dict_ref.py (issue #1303614, test67.py);
5408 borrowed_ref_[34].py (not in tracker).
5409
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00005410- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00005411 suppressed while an extension is loaded by calling SetErrorMode in
5412 dynload_win.c. The error is still reported properly.
5413
Georg Brandl3ee81df2008-05-17 18:14:43 +00005414- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005415 several extension methods and modules do not work without unicode
5416 support.
5417
Georg Brandl26543b12008-01-21 18:36:51 +00005418- Issue #1882: when compiling code from a string, encoding cookies in the

5422
Georg Brandl6caad7d2008-01-26 14:19:22 +00005423- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005424 added.
5425
Christian Heimesc94e2b52008-01-14 04:13:37 +00005426- sys.float_info / PyFloat_GetInfo: The floating point information
5427 object was converted from a dict to a specialized structseq object.
5428
Georg Brandl3ee81df2008-05-17 18:14:43 +00005429- Patch #1816: Added sys.flags structseq. It exposes the status of
5430 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005431
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432- Objects/structseq.c: Implemented new structseq representation. The
5433 patch makes structseqs (e.g. the return value of os.stat) more
5434 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005435
Georg Brandl3ee81df2008-05-17 18:14:43 +00005436- Patch #1700288: added a type attribute cache that caches method
5437 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005438
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005439- Bug #1776: __import__() no longer accepts filenames on any platform.
5440 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00005442- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5443
Georg Brandl3ee81df2008-05-17 18:14:43 +00005444- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5445 envvar and sys.dont_write_bytecode attribute. All these can be set
5446 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005447
Georg Brandl3ee81df2008-05-17 18:14:43 +00005448- Improve some exception messages when Windows fails to load an
5449 extension module. Now we get for example '%1 is not a valid Win32
5450 application' instead of 'error code 193'.

Christian Heimes0a8143f2007-12-18 23:22:54 +00005457- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005458 and INF. float("nan"), float("inf") and float("-inf") now work on
5459 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005460
Georg Brandl3ee81df2008-05-17 18:14:43 +00005461- Compiler now generates simpler and faster code for dictionary
5462 literals. The oparg for BUILD_MAP now indicates an estimated
5463 dictionary size. There is a new opcode, STORE_MAP, for adding
5464 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005493- Patch #1739468: Directories and zipfiles containing a __main__.py
5494 file can now be directly executed by passing their name to the
5495 interpreter. The directory/zipfile is automatically inserted as the
5496 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005497
Georg Brandl3ee81df2008-05-17 18:14:43 +00005498- Issue #1265: Fix a problem with sys.settrace, if the tracing
5499 function uses a generator expression when at the same time the
5500 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005501
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005502- sets and frozensets now have an isdisjoint() method.
5503
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005504- optimize the performance of builtin.sum().

5507
Georg Brandl21e99f42010-03-07 15:23:59 +00005508- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005509 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5510 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005511
Georg Brandl3ee81df2008-05-17 18:14:43 +00005512- Issue #1686386: Tuple's tp_repr did not take into account the
5513 possibility of having a self-referential tuple, which is possible
5514 from C code. Nor did object's tp_str consider that a type's tp_str
5515 could do something that could lead to an inifinite recursion.
5516 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5517 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005518
Georg Brandl3ee81df2008-05-17 18:14:43 +00005519- Issue #1164: It was possible to trigger deadlock when using the
5520 'print' statement to write to a file since the GIL was not released
5521 as needed. Now PyObject_Print() does the right thing along with
5522 various tp_print implementations of the built-in types and those in
5523 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005524
Georg Brandl3ee81df2008-05-17 18:14:43 +00005525- Issue #1147: Exceptions were directly allowing string exceptions in
5526 their throw() method even though string exceptions no longer
5527 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005528
Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00005531
Brett Cannon1e534b52007-09-07 04:18:30 +00005532- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005533 PyObject_Call() never calling back out to Python code to trigger
5534 recursion depth updates/checks. Required the creation of a static
5535 RuntimeError instance in case normalizing an exception put the
5536 recursion check value past its limit. Fixes crashers
5537 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005538

Neal Norwitz0ac60192007-05-27 04:08:54 +00005552- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005553 __*__ attributes. (Some already existed, e.g., __doc__ and
5554 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005555
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005556- Add -3 option to the interpreter to warn about features that are

5558
Georg Brandl2134e752007-05-21 20:34:16 +00005559- Patch #1686487: you can now pass any mapping after '**' in function
5560 calls.
5561
Collin Winter62903052007-05-18 23:11:24 +00005562- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005563 "except E as target:". This is to provide forwards compatibility
5564 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005568- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005569 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005570
Vinay Sajip8549ce32007-05-06 17:53:37 +00005571- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005572 setting a plain string, ie don't expand to single letter identifiers.
5573
Raymond Hettinger13936692007-04-11 18:40:58 +00005574- Request #1191699: Slices can now be pickled.
5575
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005576- Request #1193128: str.translate() now allows a None argument for
5577 translations that only remove characters without re-mapping the
5578 remaining characters.
5579
Georg Brandl5cb76c12007-03-21 09:00:39 +00005580- Patch #1682205: a TypeError while unpacking an iterable is no longer

5584
Guido van Rossum143b5642007-03-23 04:58:42 +00005585- Bug #1683368: The object.__init__() and object.__new__() methods are
5586 now stricter in rejecting excess arguments. The only time when
5587 either allows excess arguments is when it is not overridden and the
5588 other one is. For backwards compatibility, when both are
5589 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005590 warning later). Also, type.__init__() insists on the same signature
5591 as supported by type.__new__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00005593- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5594 object to complex using its __complex__() method before falling back
5595 to the __float__() method. Therefore, the functions in the cmath
5596 module now can operate on objects that define a __complex__()
5597 method.

5617
Georg Brandl871f1bc2007-03-12 13:17:36 +00005618- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005619 its argument, if it exists. If not, it will work like before. This
5620 allows customizing the output of dir() in the presence of a
5621 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00005633- Patch #703779: unset __file__ in __main__ after running a file. This

5650
Georg Brandl3ee81df2008-05-17 18:14:43 +00005651- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00005703- Bug #1545497: when given an explicit base, int() did ignore NULs
5704 embedded in the string to convert.
5705
Georg Brandl846f73a2006-10-08 07:11:54 +00005706- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00006559- The implementation of UnicodeError objects has been simplified
6560 (start and end attributes are now stored directly as Py_ssize_t
6561 members).
Walter Dörwald84a3efe2007-06-13 16:57:12 +00006562
Georg Brandl3ee81df2008-05-17 18:14:43 +00006563- Issue #829951: In the smtplib module, SMTP.starttls() now complies
6564 with RFC 3207 and forgets any knowledge obtained from the server not
6565 obtained from the TLS negotiation itself. Patch contributed by Bill
6566 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00006567
Georg Brandl3ee81df2008-05-17 18:14:43 +00006568- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00006569 that the SMTP.starttls() caller no longer needs to call ehlo()
6570 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00006571 does not claim to support starttls. Adds the
6572 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
6573 Fenner.

6653 complex, tuple, list, dict, set, and frozenset. Formerly, it would
6654 silently miscode subclasses of those types. Now, it raises a
6655 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00006656

Georg Brandl3ee81df2008-05-17 18:14:43 +00006671 time so that opening a database previously created with the DB_DUP
6672 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6673 opens. Specifically: dictionary assignment to a DB object will
6674 replace all values for a given key when the database allows
6675 duplicate values. DB users should use DB.put(k, v) when they want
6676 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00006677

6683 characters with ASCII value less than 32. Also, it correctly quotes
6684 dots only if they occur on a single line, as opposed to the previous
6685 behavior of quoting dots if they are the second character of any
6686 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00006687

7094 solely on macfs and was a no-op under OS X.
