923Core and Builtins
924-----------------
925
Ezio Melottiab2eb0e2010-06-05 19:21:32 +0000926- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
927 start byte and the continuation byte(s) are now considered invalid, instead
928 of the number of bytes specified by the start byte.
929 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
930 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
931 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
932 Previous versions returned a single u'\ufffd'.
933
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000934- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +0000935 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
936 arises from the "Overriding __eq__ blocks inheritance ..." warning
937 when turned into an exception: in this case the exception simply
938 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +0000939
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +0000940- Issue #8748: Fix two issues with comparisons between complex and integer
941 objects. (1) The comparison could incorrectly return True in some cases
942 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
943 (2) The comparison raised an OverflowError for large integers, leading
944 to unpredictable exceptions when combining integers and complex objects
945 in sets or dicts.
946
Mark Dickinson81336372010-05-30 12:12:25 +0000947- Issue #5211: Implicit coercion for the complex type is now completely
948 removed. (Coercion for arithmetic operations was already removed in 2.7
949 alpha 4, but coercion for rich comparisons was accidentally left in.)
950
Victor Stinnerc49dfcc2010-05-25 22:30:32 +0000951- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
952 and error handler, instead of writing to the C stderr file in utf-8
953
Georg Brandlfee0f442010-05-22 21:26:21 +0000954- Issue #7902: When using explicit relative import syntax, don't try implicit
955 relative import semantics.
Brett Cannoneb3cd302010-05-20 18:37:55 +0000956
Georg Brandlfee0f442010-05-22 21:26:21 +0000957- Issue #7079: Fix a possible crash when closing a file object while using it
958 from another thread. Patch by Daniel Stutzbach.
Antoine Pitrou83137c22010-05-17 19:56:59 +0000959
Victor Stinnerb65bd2e2010-06-11 19:22:28 +0000960- Issue #8868: Fix that ensures that python scripts have access to the
Ronald Oussoren27c72e92010-06-02 03:47:14 +0000961 Window Server again in a framework build on MacOSX 10.5 or earlier.

965
Georg Brandlfee0f442010-05-22 21:26:21 +0000966- Issue #5753: A new C API function, :cfunc:`PySys_SetArgvEx`, allows embedders
967 of the interpreter to set sys.argv without also modifying sys.path. This
968 helps fix `CVE-2008-5983

993
R. David Murray52dcd452010-06-02 22:03:15 +0000994- Issue #1368247: set_charset (and therefore MIMEText) now automatically

996
Alexander Belopolsky9292ee02010-05-27 20:55:27 +0000997- Issue #7150: Raise OverflowError if the result of adding or subtracting

1315 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00001327- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
1328 with a non-empty format string. This is an effort to future-proof user
1329 code. If a derived class does not currently implement __format__ but later
1330 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00001331 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00001332 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00001382- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
1383 InvalidOperation instead of returning False. (Comparisons involving a quiet
1384 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
1385 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00001386
Georg Brandlfee0f442010-05-22 21:26:21 +00001387- Issue #2531: Comparison operations between floats and Decimal instances now
1388 return a result based on the numeric values of the operands; previously they
1389 returned an arbitrary result based on the relative ordering of id(float) and
1390 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00001404- Comparisons using one of <, <=, >, >= between a complex instance and a
1405 Fractions instance now raise TypeError instead of returning True/False. This
1406 makes Fraction <=> complex comparisons consistent with int <=> complex, float

Georg Brandlba83f822010-03-14 09:50:54 +00001764- Issue #7766: Change ``sys.getwindowsversion()`` return value to a named tuple
1765 and add the additional members returned in an OSVERSIONINFOEX structure. The
1766 new members are service_pack_major, service_pack_minor, suite_mask, and

Georg Brandlba83f822010-03-14 09:50:54 +00001769- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
1770 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
1771 returning NULL. The macro now returns a statically allocated empty string
1772 instead.

1782 strings,
1783 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
1784 numeric strings corresponding to subnormal values,
1785 (3) a memory leak for some values large enough to cause overflow, and
1786 (4) a number of flaws that could lead to incorrectly rounded results.

Antoine Pitroud840e512010-02-04 20:20:18 +00001817- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00001818 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00001819 Also, raise ValueError rather than TypeError when an unknown TIPC address
1820 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001824- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00001825 file position when calling `truncate()`. It would previously change the file
1826 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00001827 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
1828

1830 class used to represent files stored inside an archive. The new
1831 implementation is significantly faster and can be wrapped in a
1832 ``io.BufferedReader`` object for more speedups. It also solves an issue
1833 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
1834 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00001844- Issue #7748: Since unicode values are supported for some metadata options in
1845 Distutils, the DistributionMetadata get_* methods will now return an utf-8
1846 encoded string for them. This ensures that the upload and register commands
1847 send the correct values to PyPI without any error.

Georg Brandlba83f822010-03-14 09:50:54 +00002118- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
2119 decimal string that's guaranteed to round back to x under correct rounding
2120 (with round-half-to-even rounding mode). Previously it gave a string based on
2121 rounding x to 17 decimal digits. repr(x) for a complex number behaves
2122 similarly. On platforms where the correctly-rounded strtod and dtoa code is
2123 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00002125- Issue #7117: On almost all platforms: float-to-string and string-to-float
2126 conversions within Python are now correctly rounded. Places these conversions
2127 occur include: str for floats and complex numbers; the float and complex
2128 constructors; old-style and new-style numeric formatting; serialization and
2129 deserialization of floats and complex numbers using marshal, pickle and json;
2130 parsing of float and imaginary literals in Python code; Decimal-to-float
2131 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00002132
Georg Brandlba83f822010-03-14 09:50:54 +00002133 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
2134 providing correctly-rounded strtod and dtoa C functions. This code is
2135 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
2136 the C compiler. There may be a small number of platforms on which correct
2137 operation of this code cannot be guaranteed, so the code is not used: notably,
2138 this applies to platforms where the C double format is not IEEE 754 binary64,
2139 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
2140 and Python's configure script is unable to determine how to change the FPU
2141 precision. On these platforms conversions use the platform strtod and dtoa,
2142 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00002144- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
2145 uses the correctly-rounded string <-> float conversions described above (when
2146 available), and so produces correctly rounded results that will display nicely
2147 under the float repr. There are two related small changes: (1) round now
2148 accepts any class with an ``__index__()`` method for its second argument (but
2149 no longer accepts floats for the second argument), and (2) an excessively
2150 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
2151 raises an exception.

Georg Brandlba83f822010-03-14 09:50:54 +00002369 untrackable objects are not tracked by the garbage collector. This can reduce
2370 the size of collections and therefore the garbage collection overhead on

Georg Brandlba83f822010-03-14 09:50:54 +00002444- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
2445 existing .py counterpart, override the co_filename attributes of all code

2501
Georg Brandlba83f822010-03-14 09:50:54 +00002502- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
2503 file objects with closefd=False. The file descriptor is still kept open but
2504 the file object behaves like a closed file. The ``FileIO`` object also got a
2505 new readonly attribute ``closefd``.

2530 this code path is really executed because I cannot move to such directory on

2557 PyUnicode_DecodeUTF8() once, remember the result and output it in a second

Walter Dörwald726ba8e2009-05-06 14:32:35 +00002561- Issue #3739: The unicode-internal encoder now reports the number of characters

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00003934- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

3936 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
3937 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon672237d2008-09-09 00:49:16 +00004009 return a list or None rather than a custom object.
4010

Brett Cannon1eaf0742008-09-02 01:25:16 +00004035 warnings.catch_warnings() along with some API cleanup. Expanding the tests
4036 for catch_warnings() also led to an improvement in the raising of a
4037 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004103What's New in Python 2.6 beta 3?
4104================================
4105
Barry Warsaw07a4a382008-08-21 01:15:08 +00004106*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00004107
4108Core and Builtins
4109-----------------
4110
Guido van Rossumf8402962008-08-20 15:01:50 +00004111- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
4112 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
4113 extensions do not automatically benefit from the class attribute
4114 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
4115 to their tp_flags field if they care. This is a backwards
4116 compatibility feature; in 3.0, all types will use the cache by
4117 default.
4118
Benjamin Petersonf647dc12008-08-20 01:27:30 +00004119- Keyword arguments can now follow starred arguments. (``f(a, *args,
4120 keyword=23)`` is now valid syntax.)
4121
Thomas Heller0ad5ae02008-08-19 19:25:04 +00004122- ctypes function pointers that are COM methods have a boolean True
4123 value again.
4124
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00004125- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
4126 by denying s# to parse objects that have a releasebuffer procedure,
4127 and introducing s*.
4128
Georg Brandl1e13ea92008-08-11 09:07:59 +00004129- Issue #3537: Fix an assertion failure when an empty but presized dict
4130 object was stored in the freelist.
4131
Mark Dickinsonb6467572008-08-04 21:30:09 +00004132- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
4133 ValueError consistently across platforms.
4134
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00004135- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
4136 (64bit Unix, for example), unichr() would truncate its argument and return
4137 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
4138
Neal Norwitze7d8be82008-07-31 17:17:14 +00004139- Apply security patches from Apple.
4140
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00004141- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
4142 PyErr_ExceptionMatches returns 0 when an exception occurs there.
4143
Antoine Pitrou92f82162008-07-25 22:22:08 +00004144- Issue #1819: function calls with several named parameters are now on
4145 average 35% faster (as measured by pybench).
4146
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00004147- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
4148 the python debugger steps into a class statement: the free variables (local
4149 variables defined in an outer scope) would be deleted from the outer scope.
4150
Gregory P. Smith0470bab2008-07-22 04:46:32 +00004151- Issue #2620: Overflow checking when allocating or reallocating memory
4152 was not always being done properly in some python types and extension
4153 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
4154 all been updated to perform better checks and places in the code that
4155 would previously leak memory on the error path when such an allocation
4156 failed have been fixed.

4159-------
4160
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00004161- Issue #3612: Added some missing basic types in ctypes.wintypes.
4162
Benjamin Petersone977ad42008-08-20 01:42:01 +00004163- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
4164 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
4165
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00004166- Issue #2234: distutils failed for some versions of the cygwin compiler. The
4167 version reported by these tools does not necessarily follow the python
4168 version numbering scheme, so the module is less strict when parsing it.
4169
Nick Coghlanf70385a2008-08-18 12:42:46 +00004170- Issue #2235: Added Py3k warnings for types which will become unhashable
4171 under the stricter __hash__ inheritance rules in 3.0. Several types
4172 which did not meet the rules for hash invariants and were already
4173 unhashable in 3.0 have now been explicitly flagged as unhashable in
4174 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
4175 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
4176
Brett Cannon88f801d2008-08-18 00:46:22 +00004177- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
4178 imported into the module but exposed as part of the module's API.
4179
Brett Cannon7b96f072008-08-18 00:41:11 +00004180- Remove an unneeded import of abc.ABCMeta from 'inspect'.
4181
Brett Cannon46225e72008-08-18 00:36:52 +00004182- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00004184- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
4185
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00004186- Issue #3575: Incremental decoder's decode function now takes bytearray
4187 by using 's*' instead of 't#'.
4188
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00004189- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00004190 fails unicode conversion on 2nd parameter. (windows only)
4191
Georg Brandl222e2082010-08-01 22:27:39 +00004192- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00004193 in a redirect.
4194
Brett Cannonabe423e2008-08-16 21:47:07 +00004195- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00004196 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00004197
Facundo Batistaeb90b782008-08-16 14:44:07 +00004198- Issue #2776: fixed small issue when handling an URL with double slash
4199 after a 302 response in the case of not going through a proxy.
4200
Antoine Pitroub90a8be2008-08-15 21:03:21 +00004201- Issue #2676: in the email package, content-type parsing was hanging on
4202 pathological input because of quadratic or exponential behaviour of a
4203 regular expression.
4204
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00004205- Issue #3476: binary buffered reading through the new "io" library is now
4206 thread-safe.
4207
Brett Cannonbf3157b2008-08-14 05:00:03 +00004208- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
4209 since mimetools itself is deprecated. Because modules are cached, all
4210 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
4211
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00004212- Issue #3134: shutil referenced undefined WindowsError symbol.
4213
Robert Schuppenies14646332008-08-10 11:01:53 +00004214- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
4215 menu entries were not deleted.
4216
Brett Cannon83e81842008-08-09 23:30:55 +00004217- Copied the implementation of reduce() to _functools.reduce() to have a
4218 version that did not raise a DeprecationWarning under -3.
4219
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00004220- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
4221 a MemoryError rather than silently stop the iteration.
4222
Guido van Rossum59ce9012008-08-09 14:55:34 +00004223- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
4224 to _sre.compile() will now be rejected. This should not affect anybody
4225 since the re.compile() function never generates invalid re-bytecode.
4226
Skip Montanaroa032bf42008-08-08 22:52:51 +00004227- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
4228 upon first access it can be automatically initialized from the csv file if
4229 it wasn't initialized during instantiation.
4230
Brett Cannon3aa2a492008-08-06 22:28:09 +00004231- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
4232 the reload() built-in has been removed.
4233
Brett Cannon7e30b672008-08-04 21:52:25 +00004234- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00004235 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,
Brett Cannon047e4a92008-08-17 04:16:04 +00004236 ConfigParser, cookielib, csv, difflib, distutils, DocXMLRPCServer, email,
4237 filecmp, fileinput, inspect, logging, modulefinder, pdb, pickle, profile,
4238 pstats, pydoc, re, rlcompleter, SimpleXMLRPCServer, shelve, socket,
4239 subprocess, sqlite3, tarfile, Tkinter, test.test_support, textwrap,
4240 threading, tokenize, traceback, urlparse, wsgiref, xml, xmlrpclib.
Brett Cannon7e30b672008-08-04 21:52:25 +00004241

Antoine Pitroude781a42008-08-09 12:43:23 +00004246 asking for a specific length. This problem only affected files opened
4247 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00004248
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00004249- Issue #3449: Update decimal module to use most recent specification
4250 (v. 1.68) and tests (v. 2.58) from IBM.

4303-----------------
4304
Georg Brandl3e483f62008-07-16 22:57:41 +00004305- Issue #3156: Fix inconsistent behavior of the bytearray type: all
4306 its methods now allow for items objects that can be converted to
4307 an integer using operator.index().
4308
Mark Dickinson64b7e502008-07-16 09:40:03 +00004309- Issue #3360: Fix incorrect parsing of '020000000000.0', which
4310 produced a ValueError instead of giving the correct float.
4311
Eric Smitha5fa5a22008-07-16 00:11:49 +00004312- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
4313 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
4314
Mark Dickinson7103aa42008-07-15 19:08:33 +00004315- Issue #3008: the float type has a new instance method 'float.hex'
4316 and a new class method 'float.fromhex' to convert floating-point
4317 numbers to and from hexadecimal strings, respectively.
4318
Nick Coghlan6d6bd442008-07-15 15:40:22 +00004319- Issue #2235: __hash__ is once again inherited by default. To allow
4320 collections.Hashable to remain meaningful in the presence of the
4321 default hash implementation (object.__hash__), it is now possible
4322 to explicit block inheritance of hash by setting __hash__=None at
4323 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
4324 level.
4325
Nick Coghlanb028f502008-07-13 14:52:36 +00004326- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
4327 the parent module cannot be found while performing an absolute import.
4328 This means that an incorrectly defined __package__ attribute will
4329 now only prevent relative imports in that module rather than causing
4330 all imports from that module to fail.
4331
Nick Coghlan14ff9942008-07-08 14:21:42 +00004332- Issue #2517: Allow unicode messages in Exceptions again by correctly
4333 bypassing the instance dictionary when looking up __unicode__ on

4337 set to a custom object whose write() method happens to install
4338 another file in sys.stdout.

Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00004340- Issue #3088: Corrected a race condition in classes derived from
4341 threading.local: the first member set by a thread could be saved in
4342 another thread's dictionary.
4343
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00004344- Issue #3004: Minor change to slice.indices(): the start and stop
4345 arguments are now treated identically, making the behaviour easier
4346 to describe and understand. For example, slice(None, -10,
4347 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
4348 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
4349 10, -1).
4350
Georg Brandl278fc502008-07-19 12:46:12 +00004351- Issue #3219: Calling a function with repeated keyword arguments,
4352 f(a=2, a=23), would not cause a syntax error. This was a regression
4353 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00004354
Georg Brandl278fc502008-07-19 12:46:12 +00004355- Issue #2862: Make int and float freelist management consistent with
4356 other freelists. Changes their CompactFreeList apis into
4357 ClearFreeList apis and calls them via gc.collect().

4363 api functions without holding the GIL, which could lead to a fatal
4364 error when they failed.
4365
Martin v. Löwisaabf4042008-08-02 07:20:25 +00004366- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004391- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
4392 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00004393 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00004394 content-length. The problem had been corrected in the 2.4 branch, but never
4395 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00004410- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
4411 handling is now the same as that of other special attributes like __name__).
4412
Brett Cannon8bb8fa52008-07-02 01:57:08 +00004413- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Georg Brandl3ee81df2008-05-17 18:14:43 +00004865- Issue #1631171: Re-implement the 'warnings' module in C (the
4866 original Python code has been kept as backup). This will allow for
4867 using the 'warning's machinery in such places as the parser where
4868 use of pure Python code is not possible. Both the ``showarning()``
4869 and ``formatwarning()`` gain an optional 'line' argument which is
4870 not called by default for backwards-compatibility reasons. Setting
4871 ``warnings.showwarning()`` to an implementation that lacks support
4872 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00004935- Issue #2550: The approach used by client/server code for obtaining
4936 ports to listen on in network-oriented tests has been refined in an
4937 effort to facilitate running multiple instances of the entire
4938 regression test suite in parallel without issue.
4939 test_support.bind_port() has been fixed such that it will always
4940 return a unique port -- which wasn't always the case with the
4941 previous implementation, especially if socket options had been set
4942 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
4943 new implementation of bind_port() will actually raise an exception
4944 if it is passed an AF_INET/SOCK_STREAM socket with either the
4945 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
4946 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
4947 the socket it's been passed. This currently only applies to
4948 Windows. This option prevents any other sockets from binding to the
4949 host/port we've bound to, thus removing the possibility of the
4950 'non-deterministic' behaviour, as Microsoft puts it, that occurs
4951 when a second SOCK_STREAM socket binds and accepts to a host/port
4952 that's already been bound by another socket. The optional preferred
4953 port parameter to bind_port() has been removed. Under no
4954 circumstances should tests be hard coding ports!
4955
4956 test_support.find_unused_port() has also been introduced, which will
4957 pass a temporary socket object to bind_port() in order to obtain an
4958 unused port. The temporary socket object is then closed and
4959 deleted, and the port is returned. This method should only be used
4960 for obtaining an unused port in order to pass to an external program
4961 (i.e. the -accept [port] argument to openssl's s_server mode) or as
4962 a parameter to a server-oriented class that doesn't give you direct
4963 access to the underlying socket used.
4964
4965 Finally, test_support.HOST has been introduced, which should be used
4966 for the host argument of any relevant socket calls (i.e. bind and
4967 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00004968
4969 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00004970 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00004971 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
4972 test_asynchat and test_socket_ssl.
4973
Georg Brandl3ee81df2008-05-17 18:14:43 +00004974 It is now possible for multiple instances of the regression test
4975 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00005254- Added the future_builtins module, which contains hex() and oct().
5255 These are the PEP 3127 version of these functions, designed to be
5256 compatible with the hex() and oct() builtins from Python 3.0. They
5257 differ slightly in their output formats from the existing, unchanged
5258 Python 2.6 builtins. The expected usage of the future_builtins
5259 module is:
5260 from future_builtins import hex, oct
5261
Eric Smith7ef40bf2008-02-20 23:34:22 +00005262- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
5263 exponents for exponents with absolute value < 100. Follows C99
5264 standard. This is a change on Windows, which would use 3 digits.
5265 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
5266 so that any alterations it does to the resulting string will be
5267 available in stringlib/formatter.h (for float.__format__).
5268
Eric Smith5a3c1352008-02-19 13:21:56 +00005269- Implemented PEP 3101, Advanced String Formatting. This adds a new
5270 builtin format(); a format() method for str and unicode; a
5271 __format__() method to object, str, unicode, int, long, float, and
5272 datetime; the class string.Formatter; and the C API
5273 PyObject_Format().
5274
Georg Brandl3ee81df2008-05-17 18:14:43 +00005275- Fixed several potential crashes, all caused by specially crafted
5276 __del__ methods exploiting objects in temporarily inconsistent
5277 state.

5288 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00005289
Georg Brandl3ee81df2008-05-17 18:14:43 +00005290- Issue #2045: Fix an infinite recursion triggered when printing a
5291 subclass of collections.defaultdict, if its default_factory is set
5292 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00005293
Christian Heimesf75dbef2008-02-08 00:11:31 +00005294- Fixed a minor memory leak in dictobject.c. The content of the free

5303
Georg Brandl3ee81df2008-05-17 18:14:43 +00005304- Issue #1983: Fixed return type of fork(), fork1() and forkpty()

5306 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005320- Patch #1473257: generator objects gain a gi_code attribute. This is
5321 the same object as the func_code attribute of the function that
5322 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00005323
Georg Brandl3ee81df2008-05-17 18:14:43 +00005324- Issue #1920: "while 0" statements were completely removed by the
5325 compiler, even in the presence of an "else" clause, which is
5326 supposed to be run when the condition is false. Now the compiler
5327 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00005328

Georg Brandl3ee81df2008-05-17 18:14:43 +00005337- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00005338 several extension methods and modules do not work without unicode
5339 support.
5340
Georg Brandl26543b12008-01-21 18:36:51 +00005341- Issue #1882: when compiling code from a string, encoding cookies in the
5342 second line of code were not always recognized correctly.
5343
Georg Brandl14404b62008-01-19 19:27:05 +00005344- Issue #1679: "0x" was taken as a valid integer literal.
5345
Georg Brandl6caad7d2008-01-26 14:19:22 +00005346- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00005347 added.
5348
Christian Heimesc94e2b52008-01-14 04:13:37 +00005349- sys.float_info / PyFloat_GetInfo: The floating point information
5350 object was converted from a dict to a specialized structseq object.
5351
Georg Brandl3ee81df2008-05-17 18:14:43 +00005352- Patch #1816: Added sys.flags structseq. It exposes the status of
5353 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00005354
Georg Brandl3ee81df2008-05-17 18:14:43 +00005355- Objects/structseq.c: Implemented new structseq representation. The
5356 patch makes structseqs (e.g. the return value of os.stat) more
5357 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00005358
Georg Brandl3ee81df2008-05-17 18:14:43 +00005359- Patch #1700288: added a type attribute cache that caches method
5360 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00005361
Neal Norwitz3fc15b82008-01-10 05:42:58 +00005362- Bug #1776: __import__() no longer accepts filenames on any platform.
5363 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00005364
Georg Brandlaed6c662008-01-07 17:25:53 +00005365- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
5366
Georg Brandl3ee81df2008-05-17 18:14:43 +00005367- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
5368 envvar and sys.dont_write_bytecode attribute. All these can be set
5369 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00005370
Georg Brandl3ee81df2008-05-17 18:14:43 +00005371- Improve some exception messages when Windows fails to load an
5372 extension module. Now we get for example '%1 is not a valid Win32
5373 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00005374
Georg Brandl3ee81df2008-05-17 18:14:43 +00005375- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005377- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
5378 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00005379
Christian Heimes0a8143f2007-12-18 23:22:54 +00005380- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00005381 and INF. float("nan"), float("inf") and float("-inf") now work on
5382 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00005383
Georg Brandl3ee81df2008-05-17 18:14:43 +00005384- Compiler now generates simpler and faster code for dictionary
5385 literals. The oparg for BUILD_MAP now indicates an estimated
5386 dictionary size. There is a new opcode, STORE_MAP, for adding
5387 entries to the dictionary.

Andrew M. Kuchling395fe442007-12-05 13:27:20 +00005397- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00005398 SystemError.
5399
Nick Coghlanef01d822007-12-03 12:55:17 +00005400- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00005416- Patch #1739468: Directories and zipfiles containing a __main__.py
5417 file can now be directly executed by passing their name to the
5418 interpreter. The directory/zipfile is automatically inserted as the
5419 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00005420
Georg Brandl3ee81df2008-05-17 18:14:43 +00005421- Issue #1265: Fix a problem with sys.settrace, if the tracing
5422 function uses a generator expression when at the same time the
5423 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00005424
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00005425- sets and frozensets now have an isdisjoint() method.
5426
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00005427- optimize the performance of builtin.sum().
5428
Neal Norwitz44f326e2007-10-05 05:29:17 +00005429- Fix warnings found by the new version of the Coverity checker.
5430
Georg Brandl21e99f42010-03-07 15:23:59 +00005431- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00005432 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
5433 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00005434
Georg Brandl3ee81df2008-05-17 18:14:43 +00005435- Issue #1686386: Tuple's tp_repr did not take into account the
5436 possibility of having a self-referential tuple, which is possible
5437 from C code. Nor did object's tp_str consider that a type's tp_str
5438 could do something that could lead to an inifinite recursion.
5439 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
5440 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00005441
Georg Brandl3ee81df2008-05-17 18:14:43 +00005442- Issue #1164: It was possible to trigger deadlock when using the
5443 'print' statement to write to a file since the GIL was not released
5444 as needed. Now PyObject_Print() does the right thing along with
5445 various tp_print implementations of the built-in types and those in
5446 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00005447
Georg Brandl3ee81df2008-05-17 18:14:43 +00005448- Issue #1147: Exceptions were directly allowing string exceptions in
5449 their throw() method even though string exceptions no longer
5450 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00005451
Georg Brandl3ee81df2008-05-17 18:14:43 +00005452- Issue #1096: Prevent a segfault from getting the repr of a very
5453 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00005454
Brett Cannon1e534b52007-09-07 04:18:30 +00005455- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00005456 PyObject_Call() never calling back out to Python code to trigger
5457 recursion depth updates/checks. Required the creation of a static
5458 RuntimeError instance in case normalizing an exception put the
5459 recursion check value past its limit. Fixes crashers
5460 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00005461
Georg Brandl3ee81df2008-05-17 18:14:43 +00005462- Patch #1031213: Decode source line in SyntaxErrors back to its

5466 with %G.
5467
Georg Brandl3ee81df2008-05-17 18:14:43 +00005468- Prevent expandtabs() on string and unicode objects from causing a
5469 segfault when a large width is passed on 32-bit platforms.

Neal Norwitz0ac60192007-05-27 04:08:54 +00005475- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00005476 __*__ attributes. (Some already existed, e.g., __doc__ and
5477 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00005478
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00005479- Add -3 option to the interpreter to warn about features that are
5480 deprecated and will be changed/removed in Python 3.0.
5481
Georg Brandl2134e752007-05-21 20:34:16 +00005482- Patch #1686487: you can now pass any mapping after '**' in function
5483 calls.
5484
Collin Winter62903052007-05-18 23:11:24 +00005485- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00005486 "except E as target:". This is to provide forwards compatibility
5487 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00005488
Brett Cannon229cee22007-05-05 01:34:02 +00005489- Deprecate BaseException.message as per PEP 352.
5490
Georg Brandl3ee81df2008-05-17 18:14:43 +00005491- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00005492 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00005493
Vinay Sajip8549ce32007-05-06 17:53:37 +00005494- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00005495 setting a plain string, ie don't expand to single letter identifiers.
5496
Raymond Hettinger13936692007-04-11 18:40:58 +00005497- Request #1191699: Slices can now be pickled.
5498
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00005499- Request #1193128: str.translate() now allows a None argument for
5500 translations that only remove characters without re-mapping the
5501 remaining characters.
5502
Georg Brandl5cb76c12007-03-21 09:00:39 +00005503- Patch #1682205: a TypeError while unpacking an iterable is no longer
5504 masked by a generic one with the message "unpack non-sequence".
5505
Neal Norwitzaa754b72007-03-21 06:39:48 +00005506- Remove unused file Python/fmod.c.
5507
Guido van Rossum143b5642007-03-23 04:58:42 +00005508- Bug #1683368: The object.__init__() and object.__new__() methods are
5509 now stricter in rejecting excess arguments. The only time when
5510 either allows excess arguments is when it is not overridden and the
5511 other one is. For backwards compatibility, when both are
5512 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00005513 warning later). Also, type.__init__() insists on the same signature
5514 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00005515
Georg Brandl3ee81df2008-05-17 18:14:43 +00005516- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
5517 object to complex using its __complex__() method before falling back
5518 to the __float__() method. Therefore, the functions in the cmath
5519 module now can operate on objects that define a __complex__()
5520 method.
Georg Brandl2b869942007-03-17 16:08:45 +00005521
Georg Brandl3ee81df2008-05-17 18:14:43 +00005522- Patch #1623563: allow __class__ assignment for classes with
5523 __slots__. The old and the new class are still required to have the
5524 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00005525
Georg Brandl3ee81df2008-05-17 18:14:43 +00005526- Patch #1642547: Fix an error/crash when encountering syntax errors

Georg Brandl3ee81df2008-05-17 18:14:43 +00005529- Patch #1462488: Python no longer segfaults when
5530 ``object.__reduce_ex__()`` is called with an object that is faking
5531 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00005532
Georg Brandl3ee81df2008-05-17 18:14:43 +00005533- Patch #1680015: Don't modify __slots__ tuple if it contains an

5537
Georg Brandl7b9c5552007-03-12 14:30:05 +00005538- Bug #1678647: write a newline after printing an exception in any
5539 case, even when converting the value to a string failed.
5540
Georg Brandl871f1bc2007-03-12 13:17:36 +00005541- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00005542 its argument, if it exists. If not, it will work like before. This
5543 allows customizing the output of dir() in the presence of a
5544 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00005545
Collin Winter276887b2007-03-12 16:11:39 +00005546- Patch #922167: Python no longer segfaults when faced with infinitely
5547 self-recursive reload() calls (as reported by bug #742342).
5548
Georg Brandl3ee81df2008-05-17 18:14:43 +00005549- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00005552- Patch #1491866: change the complex() constructor to allow
5553 parthensized forms. This means complex(repr(x)) now works instead of
5554 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00005555
Georg Brandlaa2321b2007-03-07 00:40:28 +00005556- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00005557 makes the filenames the warning module prints much more sensible
5558 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00005559
Georg Brandl49aafc92007-03-07 00:34:46 +00005560- Variant of patch #697613: don't exit the interpreter on a SystemExit
5561 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00005562 variable is given, but break into the interactive interpreter just
5563 like on other exceptions or normal program exit.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005568- Bug #1674503: close the file opened by execfile() in an error
5569 condition.
Georg Brandl098cd692007-03-06 12:17:50 +00005570
Georg Brandl0fca97a2007-03-05 22:28:08 +00005571- Patch #1674228: when assigning a slice (old-style), check for the
5572 sq_ass_slice instead of the sq_slice slot.
5573
Georg Brandl3ee81df2008-05-17 18:14:43 +00005574- When printing an unraisable error, don't print exceptions. before
5575 the name. This duplicates the behavior whening normally printing

Facundo Batistad918a652007-04-24 13:54:38 +00006067- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006068 the client's request was successfully received, understood, and
6069 accepted. Now in these cases no error is raised in urllib (issue
6070 #1177) and urllib2.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00006078- Added a timeout parameter to the constructor of other protocols
6079 (telnetlib, ftplib, smtplib and poplib). This is second part of the
6080 work started with create_connection() and timeout in httplib, and
6081 closes patch #723312.
6082
Vinay Sajip8549ce32007-05-06 17:53:37 +00006083- Patch #1676823: Added create_connection() to socket.py, which may be
6084 called with a timeout, and use it from httplib (whose HTTPConnection

Georg Brandl3ee81df2008-05-17 18:14:43 +00006109 AttributeError instead of an IOError when the server's response
6110 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00006111

Georg Brandl3ee81df2008-05-17 18:14:43 +00006116- Patch #1429539: pdb now correctly initializes the __main__ module
6117 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00006118 correctly now.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006127- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00006140- Patch #1581073: add a flag to textwrap that prevents the dropping of

6142
Georg Brandl92a6bae2007-03-13 17:43:32 +00006143- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00006144 are set for invalid interpolation sequences that would lead to
6145 errors on reading back those values.

6188 returned string up to the first NUL character.

6199
Georg Brandl3ee81df2008-05-17 18:14:43 +00006200- unittest now verifies more of its assumptions. In particular,
6201 TestCase and TestSuite subclasses (not instances) are no longer
6202 accepted in TestSuite.addTest(). This should cause no
6203 incompatibility since it never made sense with ordinary subclasses
6204 -- the failure just occurred later, with a more cumbersome
6205 exception.

6215
Georg Brandl3ee81df2008-05-17 18:14:43 +00006216- Patch #1673619: setup.py identifies extension modules it doesn't

Georg Brandl3ee81df2008-05-17 18:14:43 +00006594 time so that opening a database previously created with the DB_DUP
6595 or DB_DUPSORT flag set will keep the proper behavior on subsequent
6596 opens. Specifically: dictionary assignment to a DB object will
6597 replace all values for a given key when the database allows
6598 duplicate values. DB users should use DB.put(k, v) when they want
6599 to store duplicates; not DB[k] = v.

6606 characters with ASCII value less than 32. Also, it correctly quotes
6607 dots only if they occur on a single line, as opposed to the previous
6608 behavior of quoting dots if they are the second character of any
6609 line.
