Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000150- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
151 start byte and the continuation byte(s) are now considered invalid, instead
152 of the number of bytes specified by the start byte.
153 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
154 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
155 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
156 Previous versions returned a single u'\ufffd'.

Mark Dickinsone4b83e02010-06-05 12:14:43 +0000159 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
160 arises from the "Overriding __eq__ blocks inheritance ..." warning
161 when turned into an exception: in this case the exception simply
162 gets ignored.

Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000164- Issue #8748: Fix two issues with comparisons between complex and integer
165 objects. (1) The comparison could incorrectly return True in some cases
166 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
167 (2) The comparison raised an OverflowError for large integers, leading
168 to unpredictable exceptions when combining integers and complex objects
169 in sets or dicts.
170
Mark Dickinson81336372010-05-30 12:12:25 +0000171- Issue #5211: Implicit coercion for the complex type is now completely
172 removed. (Coercion for arithmetic operations was already removed in 2.7
173 alpha 4, but coercion for rich comparisons was accidentally left in.)
174
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000175- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding

309 non-float non-integer argument is now converted to an integer (if possible)
310 using its __int__ method. Previously, only small arguments were treated this

Georg Brandlfee0f442010-05-22 21:26:21 +0000551- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
552 with a non-empty format string. This is an effort to future-proof user
553 code. If a derived class does not currently implement __format__ but later
554 adds its own __format__, it would most likely break user code that had
555 supplied a format string. This will be changed to a DeprecationWaring in
556 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlba83f822010-03-14 09:50:54 +00001044 file position when calling `truncate()`. It would previously change the file
1045 position to the given argument, which goes against the tradition of

Georg Brandlba83f822010-03-14 09:50:54 +00001143- The ``__complex__()`` method is now looked up on the class of instances to
1144 make it consistent with other special methods.

1148
Mark Dickinson1b34d252010-01-01 17:27:30 +00001149- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00001150 DeprecationWarning when passed a float argument where an integer was expected.
1151 These functions and methods now raise TypeError instead. The majority of the
1152 effects of this change are in the extension modules, but some core functions
1153 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
1154 and many unicode/str methods.

1170 internal representation of a long.

1271 TypeError. For the 'L' format code (which previously had no warning) there is
1272 now a DeprecationWarning.

1321 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +00001322

1324 1e50 in absolute value.

Georg Brandlba83f822010-03-14 09:50:54 +00001337- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
1338 decimal string that's guaranteed to round back to x under correct rounding
1339 (with round-half-to-even rounding mode). Previously it gave a string based on
1340 rounding x to 17 decimal digits. repr(x) for a complex number behaves
1341 similarly. On platforms where the correctly-rounded strtod and dtoa code is
1342 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001343
Georg Brandlba83f822010-03-14 09:50:54 +00001344- Issue #7117: On almost all platforms: float-to-string and string-to-float
1345 conversions within Python are now correctly rounded. Places these conversions
1346 occur include: str for floats and complex numbers; the float and complex
1347 constructors; old-style and new-style numeric formatting; serialization and
1348 deserialization of floats and complex numbers using marshal, pickle and json;
1349 parsing of float and imaginary literals in Python code; Decimal-to-float
1350 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001351
Georg Brandlba83f822010-03-14 09:50:54 +00001352 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
1353 providing correctly-rounded strtod and dtoa C functions. This code is
1354 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
1355 the C compiler. There may be a small number of platforms on which correct
1356 operation of this code cannot be guaranteed, so the code is not used: notably,
1357 this applies to platforms where the C double format is not IEEE 754 binary64,
1358 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
1359 and Python's configure script is unable to determine how to change the FPU
1360 precision. On these platforms conversions use the platform strtod and dtoa,
1361 as before.
Mark Dickinsonb678de82009-11-19 18:41:49 +00001362
Georg Brandlba83f822010-03-14 09:50:54 +00001363- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
1364 uses the correctly-rounded string <-> float conversions described above (when
1365 available), and so produces correctly rounded results that will display nicely
1366 under the float repr. There are two related small changes: (1) round now
1367 accepts any class with an ``__index__()`` method for its second argument (but
1368 no longer accepts floats for the second argument), and (2) an excessively
1369 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
1370 raises an exception.

Mark Dickinsonb1d45852009-05-11 15:33:08 +00001512
Georg Brandlba83f822010-03-14 09:50:54 +00001513 (1) inf and nan strings with trailing whitespace were incorrectly rejected;
1514 (2) parsing of strings representing infinities and nans was locale aware; and
1515 (3) the interpretation of fromhex('-nan') didn't match that of float('-nan').

Georg Brandlba83f822010-03-14 09:50:54 +00001517- Issue #5920: For ``float.__format__()``, change the behavior with the empty
1518 presentation type (that is, not one of 'e', 'f', 'g', or 'n') to be like 'g'
1519 but with at least one decimal point and with a default precision
1520 of 12. Previously, the behavior the same but with a default precision of 6.
1521 This more closely matches ``str()``, and reduces surprises when adding
1522 alignment flags to the empty presentation type. This also affects the new
1523 complex.__format__ in the same way.
1524
1525- Issue #5890: In subclasses of 'property' the __doc__ attribute was shadowed by

1776 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Antoine Pitrou3c9f5412008-09-13 20:30:30 +00003132 AttributeError instead of RuntimeError, depending in which C API call
3133 exactly the recursion limit is exceeded. Consequently, both exception types
3134 are caught and silenced.

Martin v. Löwis9fa5a282008-09-11 06:53:30 +00003151- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
3152
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003153- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
3154 PyString_FromFormat or PyErr_Format to display size_t values. The macro
3155 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3156 ``printf`` function, whereas PyString_FromFormat has an independent
3157 implementation and uses "%zd" on all platforms for size_t values.
3158 This makes a difference on win64, where ``printf`` needs "%Id" to display
3159 64bit values.
3160
Benjamin Peterson97179b02008-09-09 20:55:01 +00003161- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
3162 error.
3163
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00003164- Issue #3777: long() applied to a float object now always return a long
3165 object; previously an int would be returned for small values. the __long__
3166 method is allowed to return either an int or a long, but the behaviour of
3167 float objects should not change to respect backward compatibility.
3168
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00003169- Issue #3751: str.rpartition would perform a left-partition when called with
3170 a unicode argument.
3171
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00003172- Issue #3683: Fix compilation when --without-threads is given.
3173
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003174- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00003175 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00003176 was correctly parsed but parsing of subsequent arguments failed.
3177
Vinay Sajip35e3b032008-09-01 14:33:59 +00003178- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00003179 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
3180 mechanism. In the process, fix a bug where isinstance() and issubclass(),
3181 when given a tuple of classes as second argument, were looking up
3182 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
3183 type object.
3184
Neal Norwitz18aa3882008-08-24 05:04:52 +00003185- Fix crashes on memory allocation failure found with failmalloc.
3186
3187- Fix memory leaks found with valgrind and update suppressions file.
3188
3189- Fix compiler warnings in opt mode which would lead to invalid memory reads.
3190
3191- Fix problem using wrong name in decimal module reported by pychecker.
3192
Christian Heimes7d4c3172008-08-22 19:47:25 +00003193- Silenced another compiler warning about a used but not defined
3194 function 'stringlib_contains_obj'.
3195

3197 ``__delslice__``.
3198
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00003199- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
3200 library targets in the Makefile.
3201
Gregory P. Smith980b99b2008-09-07 05:15:18 +00003202- Issue #1204: The configure script now tests for additional libraries
3203 that may be required when linking against readline. This fixes issues
3204 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

3226
Nick Coghland2e09382008-09-11 12:11:06 +00003227- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00003228 return a list or None rather than a custom object.
3229
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00003230- Issue #1638033: Cookie.Morsel gained the httponly attribute.

3254 warnings.catch_warnings() along with some API cleanup. Expanding the tests
3255 for catch_warnings() also led to an improvement in the raising of a
3256 DeprecationWarning related to warnings.warn_explicit().
3257
Benjamin Peterson973e6c22008-09-01 23:12:58 +00003258- The deprecation warnings for the old camelCase threading API were removed.

3327Core and Builtins
3328-----------------
3329
Guido van Rossumf8402962008-08-20 15:01:50 +00003330- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
3331 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
3332 extensions do not automatically benefit from the class attribute
3333 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
3334 to their tp_flags field if they care. This is a backwards
3335 compatibility feature; in 3.0, all types will use the cache by
3336 default.
3337
Benjamin Petersonf647dc12008-08-20 01:27:30 +00003338- Keyword arguments can now follow starred arguments. (``f(a, *args,
3339 keyword=23)`` is now valid syntax.)
3340
Thomas Heller0ad5ae02008-08-19 19:25:04 +00003341- ctypes function pointers that are COM methods have a boolean True
3342 value again.
3343
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00003344- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
3345 by denying s# to parse objects that have a releasebuffer procedure,
3346 and introducing s*.
3347
Georg Brandl1e13ea92008-08-11 09:07:59 +00003348- Issue #3537: Fix an assertion failure when an empty but presized dict
3349 object was stored in the freelist.
3350
Mark Dickinsonb6467572008-08-04 21:30:09 +00003351- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
3352 ValueError consistently across platforms.
3353
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00003354- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
3355 (64bit Unix, for example), unichr() would truncate its argument and return
3356 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
3357
Neal Norwitze7d8be82008-07-31 17:17:14 +00003358- Apply security patches from Apple.
3359
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00003360- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
3361 PyErr_ExceptionMatches returns 0 when an exception occurs there.
3362
Antoine Pitrou92f82162008-07-25 22:22:08 +00003363- Issue #1819: function calls with several named parameters are now on
3364 average 35% faster (as measured by pybench).
3365
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00003366- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
3367 the python debugger steps into a class statement: the free variables (local
3368 variables defined in an outer scope) would be deleted from the outer scope.
3369
Gregory P. Smith0470bab2008-07-22 04:46:32 +00003370- Issue #2620: Overflow checking when allocating or reallocating memory
3371 was not always being done properly in some python types and extension
3372 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
3373 all been updated to perform better checks and places in the code that
3374 would previously leak memory on the error path when such an allocation
3375 failed have been fixed.

Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00003380- Issue #3612: Added some missing basic types in ctypes.wintypes.
3381
Benjamin Petersone977ad42008-08-20 01:42:01 +00003382- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
3383 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
3384
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00003385- Issue #2234: distutils failed for some versions of the cygwin compiler. The
3386 version reported by these tools does not necessarily follow the python
3387 version numbering scheme, so the module is less strict when parsing it.
3388
Nick Coghlanf70385a2008-08-18 12:42:46 +00003389- Issue #2235: Added Py3k warnings for types which will become unhashable
3390 under the stricter __hash__ inheritance rules in 3.0. Several types
3391 which did not meet the rules for hash invariants and were already
3392 unhashable in 3.0 have now been explicitly flagged as unhashable in
3393 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
3394 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
3395
Brett Cannon88f801d2008-08-18 00:46:22 +00003396- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
3397 imported into the module but exposed as part of the module's API.
3398
Brett Cannon7b96f072008-08-18 00:41:11 +00003399- Remove an unneeded import of abc.ABCMeta from 'inspect'.
3400
Brett Cannon46225e72008-08-18 00:36:52 +00003401- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

3509
Nick Coghlan2a0c2b12008-08-04 12:47:17 +00003510- Issue #643841: The language reference now provides more detailed

3522-----------------
3523
Georg Brandl3e483f62008-07-16 22:57:41 +00003524- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3525 its methods now allow for items objects that can be converted to
3526 an integer using operator.index().
3527
Mark Dickinson64b7e502008-07-16 09:40:03 +00003528- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3529 produced a ValueError instead of giving the correct float.
3530
Eric Smitha5fa5a22008-07-16 00:11:49 +00003531- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3532 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3533
Mark Dickinson7103aa42008-07-15 19:08:33 +00003534- Issue #3008: the float type has a new instance method 'float.hex'
3535 and a new class method 'float.fromhex' to convert floating-point
3536 numbers to and from hexadecimal strings, respectively.
3537
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003538- Issue #2235: __hash__ is once again inherited by default. To allow
3539 collections.Hashable to remain meaningful in the presence of the
3540 default hash implementation (object.__hash__), it is now possible
3541 to explicit block inheritance of hash by setting __hash__=None at
3542 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3543 level.
3544
Nick Coghlanb028f502008-07-13 14:52:36 +00003545- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3546 the parent module cannot be found while performing an absolute import.
3547 This means that an incorrectly defined __package__ attribute will
3548 now only prevent relative imports in that module rather than causing
3549 all imports from that module to fail.
3550
Nick Coghlan14ff9942008-07-08 14:21:42 +00003551- Issue #2517: Allow unicode messages in Exceptions again by correctly

3561 another thread's dictionary.
3562
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003563- Issue #3004: Minor change to slice.indices(): the start and stop
3564 arguments are now treated identically, making the behaviour easier
3565 to describe and understand. For example, slice(None, -10,
3566 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3567 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3568 10, -1).
3569
Georg Brandl278fc502008-07-19 12:46:12 +00003570- Issue #3219: Calling a function with repeated keyword arguments,
3571 f(a=2, a=23), would not cause a syntax error. This was a regression
3572 from 2.4 caused by the switch to the new compiler.

3611 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003612 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003613 content-length. The problem had been corrected in the 2.4 branch, but never

4019
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004020- On MacOS X it is now possible to install the framework in 64-bit
4021 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00004022 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00004023
4024 This is controlled by the configure argument ``--with-universal-archs``:
4025
4026 - ``--with-universal-archs=all``: install 4-way universal
4027
4028 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
4029
4030 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
4031
4032 This option should be used in combination with ``--enable-universalsdk=``.
4033
4034 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 +00004084- Issue #1631171: Re-implement the 'warnings' module in C (the
4085 original Python code has been kept as backup). This will allow for
4086 using the 'warning's machinery in such places as the parser where
4087 use of pure Python code is not possible. Both the ``showarning()``
4088 and ``formatwarning()`` gain an optional 'line' argument which is
4089 not called by default for backwards-compatibility reasons. Setting
4090 ``warnings.showwarning()`` to an implementation that lacks support
4091 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- Issue #2550: The approach used by client/server code for obtaining
4155 ports to listen on in network-oriented tests has been refined in an
4156 effort to facilitate running multiple instances of the entire
4157 regression test suite in parallel without issue.
4158 test_support.bind_port() has been fixed such that it will always
4159 return a unique port -- which wasn't always the case with the
4160 previous implementation, especially if socket options had been set
4161 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4162 new implementation of bind_port() will actually raise an exception
4163 if it is passed an AF_INET/SOCK_STREAM socket with either the
4164 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4165 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4166 the socket it's been passed. This currently only applies to
4167 Windows. This option prevents any other sockets from binding to the
4168 host/port we've bound to, thus removing the possibility of the
4169 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4170 when a second SOCK_STREAM socket binds and accepts to a host/port
4171 that's already been bound by another socket. The optional preferred
4172 port parameter to bind_port() has been removed. Under no
4173 circumstances should tests be hard coding ports!
4174
4175 test_support.find_unused_port() has also been introduced, which will
4176 pass a temporary socket object to bind_port() in order to obtain an
4177 unused port. The temporary socket object is then closed and
4178 deleted, and the port is returned. This method should only be used
4179 for obtaining an unused port in order to pass to an external program
4180 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4181 a parameter to a server-oriented class that doesn't give you direct
4182 access to the underlying socket used.
4183
4184 Finally, test_support.HOST has been introduced, which should be used
4185 for the host argument of any relevant socket calls (i.e. bind and
4186 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004187
4188 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004189 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004190 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4191 test_asynchat and test_socket_ssl.
4192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193 It is now possible for multiple instances of the regression test
4194 suite to run in parallel without issue.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004249 \Uxxxxxxxx did not accept values outside the Basic Multilingual
4250 Plane. This affected raw unicode literals and the
4251 'raw-unicode-escape' codec. Now UTF-16 surrogates are generated in
4252 this case, like normal unicode literals and the 'unicode-escape'
4253 codec.

4462
Fred Drakea8ee94b2008-03-01 02:45:07 +00004463- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00004464 644. The mode is now inherited from the py file.

Christian Heimes5224d282008-02-23 15:01:05 +00004469
Vinay Sajipb7edfc42008-04-02 21:10:23 +00004470- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00004471 issue 215555 for a discussion.
4472
Eric Smitha73fbe72008-02-23 03:09:44 +00004473- Added the future_builtins module, which contains hex() and oct().
4474 These are the PEP 3127 version of these functions, designed to be
4475 compatible with the hex() and oct() builtins from Python 3.0. They
4476 differ slightly in their output formats from the existing, unchanged
4477 Python 2.6 builtins. The expected usage of the future_builtins
4478 module is:
4479 from future_builtins import hex, oct
4480
Eric Smith7ef40bf2008-02-20 23:34:22 +00004481- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
4482 exponents for exponents with absolute value < 100. Follows C99
4483 standard. This is a change on Windows, which would use 3 digits.
4484 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
4485 so that any alterations it does to the resulting string will be
4486 available in stringlib/formatter.h (for float.__format__).
4487
Eric Smith5a3c1352008-02-19 13:21:56 +00004488- Implemented PEP 3101, Advanced String Formatting. This adds a new
4489 builtin format(); a format() method for str and unicode; a
4490 __format__() method to object, str, unicode, int, long, float, and
4491 datetime; the class string.Formatter; and the C API
4492 PyObject_Format().
4493
Georg Brandl3ee81df2008-05-17 18:14:43 +00004494- Fixed several potential crashes, all caused by specially crafted
4495 __del__ methods exploiting objects in temporarily inconsistent
4496 state.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004505- Clear all free lists during a gc.collect() of the highest generation
4506 in order to allow pymalloc to free more arenas. Python may give back
4507 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00004508
Georg Brandl3ee81df2008-05-17 18:14:43 +00004509- Issue #2045: Fix an infinite recursion triggered when printing a
4510 subclass of collections.defaultdict, if its default_factory is set
4511 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00004512
Christian Heimesf75dbef2008-02-08 00:11:31 +00004513- Fixed a minor memory leak in dictobject.c. The content of the free
4514 list was not freed on interpreter shutdown.
4515
Georg Brandl21e99f42010-03-07 15:23:59 +00004516- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004517 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004518
Georg Brandl3ee81df2008-05-17 18:14:43 +00004519- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4520 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004521 to compact the internal free lists of pre-allocted ints and floats.
4522
Georg Brandl3ee81df2008-05-17 18:14:43 +00004523- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4524 calls. Python expected the return type int but the fork familie
4525 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004526
Georg Brandl3ee81df2008-05-17 18:14:43 +00004527- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4528 appear in the same code unit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004539- Patch #1473257: generator objects gain a gi_code attribute. This is
4540 the same object as the func_code attribute of the function that
4541 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004542
Georg Brandl3ee81df2008-05-17 18:14:43 +00004543- Issue #1920: "while 0" statements were completely removed by the
4544 compiler, even in the presence of an "else" clause, which is
4545 supposed to be run when the condition is false. Now the compiler
4546 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004547
Guido van Rossumeead05f2008-01-24 18:21:02 +00004548- A few crashers fixed: weakref_in_del.py (issue #1377858);
4549 loosing_dict_ref.py (issue #1303614, test67.py);
4550 borrowed_ref_[34].py (not in tracker).
4551
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004552- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004553 suppressed while an extension is loaded by calling SetErrorMode in
4554 dynload_win.c. The error is still reported properly.
4555
Georg Brandl3ee81df2008-05-17 18:14:43 +00004556- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004557 several extension methods and modules do not work without unicode
4558 support.
4559
Georg Brandl26543b12008-01-21 18:36:51 +00004560- Issue #1882: when compiling code from a string, encoding cookies in the

4564
Georg Brandl6caad7d2008-01-26 14:19:22 +00004565- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004566 added.
4567
Christian Heimesc94e2b52008-01-14 04:13:37 +00004568- sys.float_info / PyFloat_GetInfo: The floating point information
4569 object was converted from a dict to a specialized structseq object.
4570
Georg Brandl3ee81df2008-05-17 18:14:43 +00004571- Patch #1816: Added sys.flags structseq. It exposes the status of
4572 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004573
Georg Brandl3ee81df2008-05-17 18:14:43 +00004574- Objects/structseq.c: Implemented new structseq representation. The
4575 patch makes structseqs (e.g. the return value of os.stat) more
4576 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004577
Georg Brandl3ee81df2008-05-17 18:14:43 +00004578- Patch #1700288: added a type attribute cache that caches method
4579 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004580
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004581- Bug #1776: __import__() no longer accepts filenames on any platform.
4582 The first parameter to __import__() must be a valid module name.

Georg Brandlaed6c662008-01-07 17:25:53 +00004584- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4585
Georg Brandl3ee81df2008-05-17 18:14:43 +00004586- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4587 envvar and sys.dont_write_bytecode attribute. All these can be set
4588 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004589
Georg Brandl3ee81df2008-05-17 18:14:43 +00004590- Improve some exception messages when Windows fails to load an
4591 extension module. Now we get for example '%1 is not a valid Win32
4592 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004593

Christian Heimes0a8143f2007-12-18 23:22:54 +00004599- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004600 and INF. float("nan"), float("inf") and float("-inf") now work on
4601 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004602
Georg Brandl3ee81df2008-05-17 18:14:43 +00004603- Compiler now generates simpler and faster code for dictionary
4604 literals. The oparg for BUILD_MAP now indicates an estimated
4605 dictionary size. There is a new opcode, STORE_MAP, for adding
4606 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004635- Patch #1739468: Directories and zipfiles containing a __main__.py
4636 file can now be directly executed by passing their name to the
4637 interpreter. The directory/zipfile is automatically inserted as the
4638 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004639
Georg Brandl3ee81df2008-05-17 18:14:43 +00004640- Issue #1265: Fix a problem with sys.settrace, if the tracing
4641 function uses a generator expression when at the same time the
4642 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004643
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004644- sets and frozensets now have an isdisjoint() method.
4645
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004646- optimize the performance of builtin.sum().
4647
Neal Norwitz44f326e2007-10-05 05:29:17 +00004648- Fix warnings found by the new version of the Coverity checker.
4649
Georg Brandl21e99f42010-03-07 15:23:59 +00004650- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004651 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4652 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004653
Georg Brandl3ee81df2008-05-17 18:14:43 +00004654- Issue #1686386: Tuple's tp_repr did not take into account the
4655 possibility of having a self-referential tuple, which is possible
4656 from C code. Nor did object's tp_str consider that a type's tp_str
4657 could do something that could lead to an inifinite recursion.
4658 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4659 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004660
Georg Brandl3ee81df2008-05-17 18:14:43 +00004661- Issue #1164: It was possible to trigger deadlock when using the
4662 'print' statement to write to a file since the GIL was not released
4663 as needed. Now PyObject_Print() does the right thing along with
4664 various tp_print implementations of the built-in types and those in
4665 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004666
Georg Brandl3ee81df2008-05-17 18:14:43 +00004667- Issue #1147: Exceptions were directly allowing string exceptions in
4668 their throw() method even though string exceptions no longer
4669 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004670
Georg Brandl3ee81df2008-05-17 18:14:43 +00004671- Issue #1096: Prevent a segfault from getting the repr of a very

Brett Cannona0c05512007-09-10 21:38:27 +00004673
Brett Cannon1e534b52007-09-07 04:18:30 +00004674- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004675 PyObject_Call() never calling back out to Python code to trigger
4676 recursion depth updates/checks. Required the creation of a static
4677 RuntimeError instance in case normalizing an exception put the
4678 recursion check value past its limit. Fixes crashers
4679 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004680

Neal Norwitz0ac60192007-05-27 04:08:54 +00004694- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004695 __*__ attributes. (Some already existed, e.g., __doc__ and
4696 __name__.)

Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004698- Add -3 option to the interpreter to warn about features that are
4699 deprecated and will be changed/removed in Python 3.0.
4700
Georg Brandl2134e752007-05-21 20:34:16 +00004701- Patch #1686487: you can now pass any mapping after '**' in function
4702 calls.
4703
Collin Winter62903052007-05-18 23:11:24 +00004704- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004705 "except E as target:". This is to provide forwards compatibility
4706 with Python 3.0.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004710- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004711 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004712
Vinay Sajip8549ce32007-05-06 17:53:37 +00004713- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004714 setting a plain string, ie don't expand to single letter identifiers.
4715
Raymond Hettinger13936692007-04-11 18:40:58 +00004716- Request #1191699: Slices can now be pickled.
4717
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004718- Request #1193128: str.translate() now allows a None argument for
4719 translations that only remove characters without re-mapping the
4720 remaining characters.
4721
Georg Brandl5cb76c12007-03-21 09:00:39 +00004722- Patch #1682205: a TypeError while unpacking an iterable is no longer
4723 masked by a generic one with the message "unpack non-sequence".
4724

4726
Guido van Rossum143b5642007-03-23 04:58:42 +00004727- Bug #1683368: The object.__init__() and object.__new__() methods are
4728 now stricter in rejecting excess arguments. The only time when
4729 either allows excess arguments is when it is not overridden and the
4730 other one is. For backwards compatibility, when both are
4731 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004732 warning later). Also, type.__init__() insists on the same signature

Georg Brandl3ee81df2008-05-17 18:14:43 +00004735- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4736 object to complex using its __complex__() method before falling back
4737 to the __float__() method. Therefore, the functions in the cmath
4738 module now can operate on objects that define a __complex__()
4739 method.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004761 its argument, if it exists. If not, it will work like before. This
4762 allows customizing the output of dir() in the presence of a
4763 __getattr__().

Georg Brandlaa2321b2007-03-07 00:40:28 +00004775- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00004776 makes the filenames the warning module prints much more sensible
4777 when a PYTHONSTARTUP file is used.

4791 sq_ass_slice instead of the sq_slice slot.
4792
Georg Brandl3ee81df2008-05-17 18:14:43 +00004793- When printing an unraisable error, don't print exceptions. before

Georg Brandl2c1375c2006-10-12 11:27:59 +00004845- Bug #1545497: when given an explicit base, int() did ignore NULs
4846 embedded in the string to convert.
4847
Georg Brandl846f73a2006-10-08 07:11:54 +00004848- Bug #1569998: break inside a try statement (outside a loop) is now

Georg Brandl3ee81df2008-05-17 18:14:43 +00004896 generator expressions (x for x, in ... ) works again. Fixing this
4897 problem required changing the .pyc magic number. This means that
4898 .pyc files generated before 2.5c2 will be regenerated.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005705- Issue #829951: In the smtplib module, SMTP.starttls() now complies
5706 with RFC 3207 and forgets any knowledge obtained from the server not
5707 obtained from the TLS negotiation itself. Patch contributed by Bill
5708 Fenner.
Gregory P. Smith2b3ba582008-01-17 08:03:17 +00005709
Georg Brandl3ee81df2008-05-17 18:14:43 +00005710- Issue #1339: The smtplib.SMTP class has been refactored a bit such
Gregory P. Smithbde4ae42008-01-17 08:35:49 +00005711 that the SMTP.starttls() caller no longer needs to call ehlo()
5712 beforehand. SMTP.starttls() now raises an exception of the server
Georg Brandl3ee81df2008-05-17 18:14:43 +00005713 does not claim to support starttls. Adds the
5714 SMTP.ehlo_or_helo_if_needed() method. Patch contributed by Bill
5715 Fenner.

5795 complex, tuple, list, dict, set, and frozenset. Formerly, it would
5796 silently miscode subclasses of those types. Now, it raises a
5797 ValueError instead.
Raymond Hettinger12e94202007-11-07 01:13:09 +00005798

Georg Brandl3ee81df2008-05-17 18:14:43 +00005813 time so that opening a database previously created with the DB_DUP
5814 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5815 opens. Specifically: dictionary assignment to a DB object will
5816 replace all values for a given key when the database allows
5817 duplicate values. DB users should use DB.put(k, v) when they want
5818 to store duplicates; not DB[k] = v.
Gregory P. Smithec10a4a2007-11-05 02:32:26 +00005819

5825 characters with ASCII value less than 32. Also, it correctly quotes
5826 dots only if they occur on a single line, as opposed to the previous
5827 behavior of quoting dots if they are the second character of any
5828 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00005829
