13 is modified during the lifetime of the Python process after zipimport has
14 already cached the zip's table of contents we detect this and recover

Ned Deily18fae3f2013-01-31 01:24:55 -08001582- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1583 In particular, fix extension module build failures when trying to use
1584 32-bit-only installer Pythons on systems with Xcode 4 (currently
1585 OS X 10.8, 10.7, and optionally 10.6).
1586 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1587 * Since Xcode 4 removes ppc support, extension module builds now
1588 check for ppc compiler support and by default remove ppc and
1589 ppc64 archs when they are not available.
1590 * Extension module builds now revert to using system installed
1591 headers and libs (/usr and /System/Library) if the SDK used
1592 to build the interpreter is not installed or has moved.
1593 * Try to avoid building extension modules with deprecated
1594 and problematic Apple llvm-gcc compiler. If original compiler
1595 is not available, use clang instead by default.

2027 Distutils-based packages with C extension modules may fail because
2028 Apple has removed gcc-4.2, the version used to build python.org
2029 64-bit/32-bit Pythons. If the user does not explicitly override
2030 the default C compiler by setting the CC environment variable,
2031 Distutils will now attempt to compile extension modules with clang

Ned Deily87e82bb2011-06-28 19:52:59 -07002287- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2288 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2289 interpreter process. This could cause failures in non-Distutils subprocesses
2290 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002291 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002292 deployment target only in the environment of each build subprocess. It is
2293 still possible to globally override the default by setting
2294 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2295 greater or equal to the default value, the value with which the interpreter
2296 was built.

2325 updating the check interval, so if the user decreases the check interval,
2326 the ticker doesn't have to wind down to zero from the old starting point
2327 before the new interval takes effect. And if the user increases the
2328 interval, it makes sure the new limit takes effect right away rather have an
2329 early task switch before recognizing the new interval.

3308
Raymond Hettinger20397532010-09-12 02:11:45 +00003309- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3310 This prevents user-created self-referencing ordered dictionaries from
3311 becoming permanently uncollectable GC garbage. The downside is that
3312 removing __del__ means that the internal doubly-linked list has to wait for
3313 GC collection rather than freeing memory immediately when the refcnt drops
3314 to zero.
3315
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003316- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3319
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003320- Issue #9792: In case of connection failure, socket.create_connection()
3321 would swallow the exception and raise a new one, making it impossible
3322 to fetch the original errno, or to filter timeout errors. Now the
3323 original error is re-raised.
3324
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003325- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

3344
R. David Murray7c4bf552010-08-25 01:45:57 +00003345- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3346 character years even if the message contains RFC822 two character years.
3347
Daniel Stutzbach91287322010-08-24 21:09:30 +00003348- Issue #8750: Fixed MutableSet's methods to correctly handle

3361
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003362- Issue #9617: Signals received during a low-level write operation aren't
3363 ignored by the buffered IO layer anymore.
3364
Benjamin Peterson52c36052010-08-21 03:03:22 +00003365- Issue #2521: Use weakrefs on for caching in the abc module, so that classes

3367
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003368- Issue #9626: the view methods for collections.OrderedDict() were returning
3369 the unordered versions inherited from dict. Those methods are now
3370 overridden to provide ordered views.

3373 comment indicating they are generated. Manually maintained MANIFESTs
3374 without this marker will not be overwritten or removed.
3375
Antoine Pitroue1436d12010-08-12 15:25:51 +00003376- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3377 and a BadZipfile error is raised if it doesn't match (as used to be the
3378 case in Python 2.5 and earlier).
3379
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003380- Issue #9550: a BufferedReader could issue an additional read when the
3381 original read request had been satisfied, which could block indefinitely
3382 when the underlying raw IO channel was e.g. a socket. Report and original
3383 patch by Jason V. Miller.
3384
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003385- Issue #9551: Don't raise TypeError when setting the value to None for

3777 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3778 Previous versions returned a single u'\ufffd'.

3787 objects. (1) The comparison could incorrectly return True in some cases
3788 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4038 indefinitely if the other end didn't respond.
4039
Georg Brandlfee0f442010-05-22 21:26:21 +00004040- The do_handshake() method of SSL objects now adjusts the blocking mode of the

4159
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004160- Issue #8329: Don't return the same lists from select.select when no fds are
4161 changed.

Georg Brandlfee0f442010-05-22 21:26:21 +00004173- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4174 with a non-empty format string. This is an effort to future-proof user
4175 code. If a derived class does not currently implement __format__ but later
4176 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004177 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004178 Python 3.3 and it will be an error in Python 3.4.

4229 InvalidOperation instead of returning False. (Comparisons involving a quiet
4230 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4231 signaling NaNs remain unhashable.

Georg Brandlfee0f442010-05-22 21:26:21 +00004233- Issue #2531: Comparison operations between floats and Decimal instances now
4234 return a result based on the numeric values of the operands; previously they

4251 Fractions instance now raise TypeError instead of returning True/False. This
4252 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4253 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004671 file position when calling `truncate()`. It would previously change the file
4672 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004673 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4674

4676 class used to represent files stored inside an archive. The new
4677 implementation is significantly faster and can be wrapped in a
4678 ``io.BufferedReader`` object for more speedups. It also solves an issue
4679 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

4692 encoded string for them. This ensures that the upload and register commands
4693 send the correct values to PyPI without any error.

4769
Georg Brandlba83f822010-03-14 09:50:54 +00004770- The ``__complex__()`` method is now looked up on the class of instances to
4771 make it consistent with other special methods.
Benjamin Petersonecdae192010-01-04 00:43:01 +00004772
Antoine Pitrou5b7139a2010-01-02 21:12:58 +00004773- Issue #7462: Implement the stringlib fast search algorithm for the `rfind`,

4775
Mark Dickinson1b34d252010-01-01 17:27:30 +00004776- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004777 DeprecationWarning when passed a float argument where an integer was expected.
4778 These functions and methods now raise TypeError instead. The majority of the
4779 effects of this change are in the extension modules, but some core functions
4780 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4781 and many unicode/str methods.

4793
Georg Brandlba83f822010-03-14 09:50:54 +00004794- Issue #1811: Improve accuracy and cross-platform consistency for true division
4795 of integers: the result of a/b is now correctly rounded for ints a and b (at
4796 least on IEEE 754 platforms), and in particular does not depend on the
4797 internal representation of a long.

4805
Georg Brandlba83f822010-03-14 09:50:54 +00004806 These executables now work properly with the arch(1) command: ``arch -ppc
4807 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004830 renaming of `cPickle` to `pickle`. The warning was annoying since there's no

Georg Brandlba83f822010-03-14 09:50:54 +00004970- Issue #7117: On almost all platforms: float-to-string and string-to-float
4971 conversions within Python are now correctly rounded. Places these conversions
4972 occur include: str for floats and complex numbers; the float and complex
4973 constructors; old-style and new-style numeric formatting; serialization and
4974 deserialization of floats and complex numbers using marshal, pickle and json;
4975 parsing of float and imaginary literals in Python code; Decimal-to-float
4976 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004977
Georg Brandlba83f822010-03-14 09:50:54 +00004978 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4979 providing correctly-rounded strtod and dtoa C functions. This code is
4980 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4981 the C compiler. There may be a small number of platforms on which correct
4982 operation of this code cannot be guaranteed, so the code is not used: notably,
4983 this applies to platforms where the C double format is not IEEE 754 binary64,
4984 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4985 and Python's configure script is unable to determine how to change the FPU
4986 precision. On these platforms conversions use the platform strtod and dtoa,
4987 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004989- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4990 uses the correctly-rounded string <-> float conversions described above (when
4991 available), and so produces correctly rounded results that will display nicely
4992 under the float repr. There are two related small changes: (1) round now
4993 accepts any class with an ``__index__()`` method for its second argument (but
4994 no longer accepts floats for the second argument), and (2) an excessively
4995 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4996 raises an exception.

6581 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6582 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6583 neither __int__ nor __long__, TypeError used to be raised (with a
6584 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6585 struct.error in other cases.

6588 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006782- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6784 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6785 ``printf`` function, whereas PyString_FromFormat has an independent
6786 implementation and uses "%zd" on all platforms for size_t values.

Brett Cannon1eaf0742008-09-02 01:25:16 +00006883 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6884 for catch_warnings() also led to an improvement in the raising of a
6885 DeprecationWarning related to warnings.warn_explicit().
6886

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006951What's New in Python 2.6 beta 3?
6952================================
6953
Barry Warsaw07a4a382008-08-21 01:15:08 +00006954*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006955
6956Core and Builtins
6957-----------------
6958
Guido van Rossumf8402962008-08-20 15:01:50 +00006959- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6960 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6961 extensions do not automatically benefit from the class attribute
6962 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6963 to their tp_flags field if they care. This is a backwards
6964 compatibility feature; in 3.0, all types will use the cache by
6965 default.
6966
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006967- Keyword arguments can now follow starred arguments. (``f(a, *args,
6968 keyword=23)`` is now valid syntax.)
6969
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006970- ctypes function pointers that are COM methods have a boolean True
6971 value again.
6972
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006973- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6974 by denying s# to parse objects that have a releasebuffer procedure,
6975 and introducing s*.
6976
Georg Brandl1e13ea92008-08-11 09:07:59 +00006977- Issue #3537: Fix an assertion failure when an empty but presized dict
6978 object was stored in the freelist.
6979
Mark Dickinsonb6467572008-08-04 21:30:09 +00006980- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6981 ValueError consistently across platforms.
6982
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006983- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6984 (64bit Unix, for example), unichr() would truncate its argument and return
6985 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6986
Neal Norwitze7d8be82008-07-31 17:17:14 +00006987- Apply security patches from Apple.
6988
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006989- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6990 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6991
Antoine Pitrou92f82162008-07-25 22:22:08 +00006992- Issue #1819: function calls with several named parameters are now on
6993 average 35% faster (as measured by pybench).
6994
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006995- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6996 the python debugger steps into a class statement: the free variables (local
6997 variables defined in an outer scope) would be deleted from the outer scope.
6998
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006999- Issue #2620: Overflow checking when allocating or reallocating memory
7000 was not always being done properly in some python types and extension
7001 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
7002 all been updated to perform better checks and places in the code that
7003 would previously leak memory on the error path when such an allocation
7004 failed have been fixed.

7007-------
7008
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007009- Issue #3612: Added some missing basic types in ctypes.wintypes.
7010
Benjamin Petersone977ad42008-08-20 01:42:01 +00007011- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7012 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7013
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007014- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7015 version reported by these tools does not necessarily follow the python
7016 version numbering scheme, so the module is less strict when parsing it.
7017
Nick Coghlanf70385a2008-08-18 12:42:46 +00007018- Issue #2235: Added Py3k warnings for types which will become unhashable
7019 under the stricter __hash__ inheritance rules in 3.0. Several types
7020 which did not meet the rules for hash invariants and were already
7021 unhashable in 3.0 have now been explicitly flagged as unhashable in
7022 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7023 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7024
Brett Cannon88f801d2008-08-18 00:46:22 +00007025- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7026 imported into the module but exposed as part of the module's API.
7027
Brett Cannon7b96f072008-08-18 00:41:11 +00007028- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7029
Brett Cannon46225e72008-08-18 00:36:52 +00007030- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007032- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7033
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007034- Issue #3575: Incremental decoder's decode function now takes bytearray
7035 by using 's*' instead of 't#'.
7036
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007037- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007038 fails unicode conversion on 2nd parameter. (windows only)
7039
Georg Brandl222e2082010-08-01 22:27:39 +00007040- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007041 in a redirect.
7042
Brett Cannonabe423e2008-08-16 21:47:07 +00007043- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007044 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007045
Facundo Batistaeb90b782008-08-16 14:44:07 +00007046- Issue #2776: fixed small issue when handling an URL with double slash
7047 after a 302 response in the case of not going through a proxy.
7048
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007049- Issue #2676: in the email package, content-type parsing was hanging on
7050 pathological input because of quadratic or exponential behaviour of a
7051 regular expression.
7052
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007053- Issue #3476: binary buffered reading through the new "io" library is now
7054 thread-safe.
7055
Brett Cannonbf3157b2008-08-14 05:00:03 +00007056- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7057 since mimetools itself is deprecated. Because modules are cached, all
7058 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7059
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007060- Issue #3134: shutil referenced undefined WindowsError symbol.
7061
Robert Schuppenies14646332008-08-10 11:01:53 +00007062- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7063 menu entries were not deleted.
7064
Brett Cannon83e81842008-08-09 23:30:55 +00007065- Copied the implementation of reduce() to _functools.reduce() to have a
7066 version that did not raise a DeprecationWarning under -3.
7067
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007068- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7069 a MemoryError rather than silently stop the iteration.
7070
Guido van Rossum59ce9012008-08-09 14:55:34 +00007071- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7072 to _sre.compile() will now be rejected. This should not affect anybody
7073 since the re.compile() function never generates invalid re-bytecode.
7074
Skip Montanaroa032bf42008-08-08 22:52:51 +00007075- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7076 upon first access it can be automatically initialized from the csv file if
7077 it wasn't initialized during instantiation.
7078
Brett Cannon3aa2a492008-08-06 22:28:09 +00007079- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7080 the reload() built-in has been removed.
7081
Brett Cannon7e30b672008-08-04 21:52:25 +00007082- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007083 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007094 asking for a specific length. This problem only affected files opened
7095 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007096
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007097- Issue #3449: Update decimal module to use most recent specification
7098 (v. 1.68) and tests (v. 2.58) from IBM.

7151-----------------
7152
Georg Brandl3e483f62008-07-16 22:57:41 +00007153- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7154 its methods now allow for items objects that can be converted to
7155 an integer using operator.index().
7156
Mark Dickinson64b7e502008-07-16 09:40:03 +00007157- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7158 produced a ValueError instead of giving the correct float.
7159
Eric Smitha5fa5a22008-07-16 00:11:49 +00007160- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7161 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7162
Mark Dickinson7103aa42008-07-15 19:08:33 +00007163- Issue #3008: the float type has a new instance method 'float.hex'
7164 and a new class method 'float.fromhex' to convert floating-point
7165 numbers to and from hexadecimal strings, respectively.
7166
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007167- Issue #2235: __hash__ is once again inherited by default. To allow
7168 collections.Hashable to remain meaningful in the presence of the
7169 default hash implementation (object.__hash__), it is now possible
7170 to explicit block inheritance of hash by setting __hash__=None at
7171 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7172 level.
7173
Nick Coghlanb028f502008-07-13 14:52:36 +00007174- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7175 the parent module cannot be found while performing an absolute import.
7176 This means that an incorrectly defined __package__ attribute will
7177 now only prevent relative imports in that module rather than causing
7178 all imports from that module to fail.
7179
Nick Coghlan14ff9942008-07-08 14:21:42 +00007180- Issue #2517: Allow unicode messages in Exceptions again by correctly

7190 another thread's dictionary.
7191
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007192- Issue #3004: Minor change to slice.indices(): the start and stop
7193 arguments are now treated identically, making the behaviour easier
7194 to describe and understand. For example, slice(None, -10,
7195 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7196 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7197 10, -1).
7198
Georg Brandl278fc502008-07-19 12:46:12 +00007199- Issue #3219: Calling a function with repeated keyword arguments,
7200 f(a=2, a=23), would not cause a syntax error. This was a regression
7201 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007202
Georg Brandl278fc502008-07-19 12:46:12 +00007203- Issue #2862: Make int and float freelist management consistent with
7204 other freelists. Changes their CompactFreeList apis into

7211 api functions without holding the GIL, which could lead to a fatal
7212 error when they failed.
7213
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007214- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007239- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7240 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007241 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007242 content-length. The problem had been corrected in the 2.4 branch, but never
7243 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007258- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007710- Issue #1631171: Re-implement the 'warnings' module in C (the
7711 original Python code has been kept as backup). This will allow for
7712 using the 'warning's machinery in such places as the parser where
7713 use of pure Python code is not possible. Both the ``showarning()``
7714 and ``formatwarning()`` gain an optional 'line' argument which is
7715 not called by default for backwards-compatibility reasons. Setting
7716 ``warnings.showwarning()`` to an implementation that lacks support
7717 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007780- Issue #2550: The approach used by client/server code for obtaining
7781 ports to listen on in network-oriented tests has been refined in an
7782 effort to facilitate running multiple instances of the entire
7783 regression test suite in parallel without issue.
7784 test_support.bind_port() has been fixed such that it will always
7785 return a unique port -- which wasn't always the case with the
7786 previous implementation, especially if socket options had been set
7787 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7788 new implementation of bind_port() will actually raise an exception
7789 if it is passed an AF_INET/SOCK_STREAM socket with either the
7790 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7791 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7792 the socket it's been passed. This currently only applies to
7793 Windows. This option prevents any other sockets from binding to the
7794 host/port we've bound to, thus removing the possibility of the
7795 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7796 when a second SOCK_STREAM socket binds and accepts to a host/port
7797 that's already been bound by another socket. The optional preferred
7798 port parameter to bind_port() has been removed. Under no
7799 circumstances should tests be hard coding ports!
7800
7801 test_support.find_unused_port() has also been introduced, which will
7802 pass a temporary socket object to bind_port() in order to obtain an
7803 unused port. The temporary socket object is then closed and
7804 deleted, and the port is returned. This method should only be used
7805 for obtaining an unused port in order to pass to an external program
7806 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7807 a parameter to a server-oriented class that doesn't give you direct
7808 access to the underlying socket used.
7809
7810 Finally, test_support.HOST has been introduced, which should be used
7811 for the host argument of any relevant socket calls (i.e. bind and
7812 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007813
7814 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007815 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007816 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7817 test_asynchat and test_socket_ssl.
7818
Georg Brandl3ee81df2008-05-17 18:14:43 +00007819 It is now possible for multiple instances of the regression test
7820 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008099- Added the future_builtins module, which contains hex() and oct().
8100 These are the PEP 3127 version of these functions, designed to be
8101 compatible with the hex() and oct() builtins from Python 3.0. They
8102 differ slightly in their output formats from the existing, unchanged
8103 Python 2.6 builtins. The expected usage of the future_builtins
8104 module is:
8105 from future_builtins import hex, oct
8106
Eric Smith7ef40bf2008-02-20 23:34:22 +00008107- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8108 exponents for exponents with absolute value < 100. Follows C99
8109 standard. This is a change on Windows, which would use 3 digits.
8110 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8111 so that any alterations it does to the resulting string will be
8112 available in stringlib/formatter.h (for float.__format__).
8113
Eric Smith5a3c1352008-02-19 13:21:56 +00008114- Implemented PEP 3101, Advanced String Formatting. This adds a new
8115 builtin format(); a format() method for str and unicode; a
8116 __format__() method to object, str, unicode, int, long, float, and
8117 datetime; the class string.Formatter; and the C API
8118 PyObject_Format().
8119
Georg Brandl3ee81df2008-05-17 18:14:43 +00008120- Fixed several potential crashes, all caused by specially crafted
8121 __del__ methods exploiting objects in temporarily inconsistent
8122 state.

8133 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008134
Georg Brandl3ee81df2008-05-17 18:14:43 +00008135- Issue #2045: Fix an infinite recursion triggered when printing a
8136 subclass of collections.defaultdict, if its default_factory is set
8137 to a bound method.

8148
Georg Brandl3ee81df2008-05-17 18:14:43 +00008149- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8150 calls. Python expected the return type int but the fork familie
8151 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008165- Patch #1473257: generator objects gain a gi_code attribute. This is
8166 the same object as the func_code attribute of the function that
8167 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008168
Georg Brandl3ee81df2008-05-17 18:14:43 +00008169- Issue #1920: "while 0" statements were completely removed by the
8170 compiler, even in the presence of an "else" clause, which is
8171 supposed to be run when the condition is false. Now the compiler
8172 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008173

8190
Georg Brandl6caad7d2008-01-26 14:19:22 +00008191- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008192 added.
8193
Christian Heimesc94e2b52008-01-14 04:13:37 +00008194- sys.float_info / PyFloat_GetInfo: The floating point information
8195 object was converted from a dict to a specialized structseq object.
8196
Georg Brandl3ee81df2008-05-17 18:14:43 +00008197- Patch #1816: Added sys.flags structseq. It exposes the status of
8198 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008199
Georg Brandl3ee81df2008-05-17 18:14:43 +00008200- Objects/structseq.c: Implemented new structseq representation. The
8201 patch makes structseqs (e.g. the return value of os.stat) more
8202 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008203
Georg Brandl3ee81df2008-05-17 18:14:43 +00008204- Patch #1700288: added a type attribute cache that caches method
8205 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008206
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008207- Bug #1776: __import__() no longer accepts filenames on any platform.
8208 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008209
Georg Brandlaed6c662008-01-07 17:25:53 +00008210- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8211
Georg Brandl3ee81df2008-05-17 18:14:43 +00008212- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8213 envvar and sys.dont_write_bytecode attribute. All these can be set
8214 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008215
Georg Brandl3ee81df2008-05-17 18:14:43 +00008216- Improve some exception messages when Windows fails to load an
8217 extension module. Now we get for example '%1 is not a valid Win32
8218 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008219

8223 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008224
Christian Heimes0a8143f2007-12-18 23:22:54 +00008225- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008226 and INF. float("nan"), float("inf") and float("-inf") now work on
8227 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008228
Georg Brandl3ee81df2008-05-17 18:14:43 +00008229- Compiler now generates simpler and faster code for dictionary
8230 literals. The oparg for BUILD_MAP now indicates an estimated
8231 dictionary size. There is a new opcode, STORE_MAP, for adding
8232 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Patch #1739468: Directories and zipfiles containing a __main__.py
8262 file can now be directly executed by passing their name to the
8263 interpreter. The directory/zipfile is automatically inserted as the
8264 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008265
Georg Brandl3ee81df2008-05-17 18:14:43 +00008266- Issue #1265: Fix a problem with sys.settrace, if the tracing
8267 function uses a generator expression when at the same time the
8268 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008269
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008270- sets and frozensets now have an isdisjoint() method.
8271
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008272- optimize the performance of builtin.sum().
8273
Neal Norwitz44f326e2007-10-05 05:29:17 +00008274- Fix warnings found by the new version of the Coverity checker.
8275
Georg Brandl21e99f42010-03-07 15:23:59 +00008276- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008277 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8278 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008279
Georg Brandl3ee81df2008-05-17 18:14:43 +00008280- Issue #1686386: Tuple's tp_repr did not take into account the
8281 possibility of having a self-referential tuple, which is possible
8282 from C code. Nor did object's tp_str consider that a type's tp_str
8283 could do something that could lead to an inifinite recursion.
8284 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8285 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008286
Georg Brandl3ee81df2008-05-17 18:14:43 +00008287- Issue #1164: It was possible to trigger deadlock when using the
8288 'print' statement to write to a file since the GIL was not released
8289 as needed. Now PyObject_Print() does the right thing along with
8290 various tp_print implementations of the built-in types and those in
8291 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008292
Georg Brandl3ee81df2008-05-17 18:14:43 +00008293- Issue #1147: Exceptions were directly allowing string exceptions in
8294 their throw() method even though string exceptions no longer
8295 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008296
Georg Brandl3ee81df2008-05-17 18:14:43 +00008297- Issue #1096: Prevent a segfault from getting the repr of a very
8298 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008299
Brett Cannon1e534b52007-09-07 04:18:30 +00008300- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008301 PyObject_Call() never calling back out to Python code to trigger
8302 recursion depth updates/checks. Required the creation of a static
8303 RuntimeError instance in case normalizing an exception put the
8304 recursion check value past its limit. Fixes crashers
8305 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008306
Georg Brandl3ee81df2008-05-17 18:14:43 +00008307- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008320- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008321 __*__ attributes. (Some already existed, e.g., __doc__ and
8322 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008323
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008324- Add -3 option to the interpreter to warn about features that are
8325 deprecated and will be changed/removed in Python 3.0.
8326
Georg Brandl2134e752007-05-21 20:34:16 +00008327- Patch #1686487: you can now pass any mapping after '**' in function
8328 calls.
8329
Collin Winter62903052007-05-18 23:11:24 +00008330- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008331 "except E as target:". This is to provide forwards compatibility
8332 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008333
Brett Cannon229cee22007-05-05 01:34:02 +00008334- Deprecate BaseException.message as per PEP 352.
8335
Georg Brandl3ee81df2008-05-17 18:14:43 +00008336- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008337 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008338
Vinay Sajip8549ce32007-05-06 17:53:37 +00008339- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008340 setting a plain string, ie don't expand to single letter identifiers.
8341
Raymond Hettinger13936692007-04-11 18:40:58 +00008342- Request #1191699: Slices can now be pickled.
8343
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008344- Request #1193128: str.translate() now allows a None argument for
8345 translations that only remove characters without re-mapping the
8346 remaining characters.
8347
Georg Brandl5cb76c12007-03-21 09:00:39 +00008348- Patch #1682205: a TypeError while unpacking an iterable is no longer
8349 masked by a generic one with the message "unpack non-sequence".
8350
Neal Norwitzaa754b72007-03-21 06:39:48 +00008351- Remove unused file Python/fmod.c.
8352
Guido van Rossum143b5642007-03-23 04:58:42 +00008353- Bug #1683368: The object.__init__() and object.__new__() methods are
8354 now stricter in rejecting excess arguments. The only time when
8355 either allows excess arguments is when it is not overridden and the
8356 other one is. For backwards compatibility, when both are
8357 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008358 warning later). Also, type.__init__() insists on the same signature
8359 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008360
Georg Brandl3ee81df2008-05-17 18:14:43 +00008361- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8362 object to complex using its __complex__() method before falling back
8363 to the __float__() method. Therefore, the functions in the cmath
8364 module now can operate on objects that define a __complex__()
8365 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008366
Georg Brandl3ee81df2008-05-17 18:14:43 +00008367- Patch #1623563: allow __class__ assignment for classes with
8368 __slots__. The old and the new class are still required to have the
8369 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008370
Georg Brandl3ee81df2008-05-17 18:14:43 +00008371- Patch #1642547: Fix an error/crash when encountering syntax errors

8375 ``object.__reduce_ex__()`` is called with an object that is faking
8376 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008377
Georg Brandl3ee81df2008-05-17 18:14:43 +00008378- Patch #1680015: Don't modify __slots__ tuple if it contains an

8382
Georg Brandl7b9c5552007-03-12 14:30:05 +00008383- Bug #1678647: write a newline after printing an exception in any
8384 case, even when converting the value to a string failed.
8385
Georg Brandl871f1bc2007-03-12 13:17:36 +00008386- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008387 its argument, if it exists. If not, it will work like before. This
8388 allows customizing the output of dir() in the presence of a
8389 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008390
Collin Winter276887b2007-03-12 16:11:39 +00008391- Patch #922167: Python no longer segfaults when faced with infinitely
8392 self-recursive reload() calls (as reported by bug #742342).
8393
Georg Brandl3ee81df2008-05-17 18:14:43 +00008394- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008397- Patch #1491866: change the complex() constructor to allow
8398 parthensized forms. This means complex(repr(x)) now works instead of
8399 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008400
Georg Brandlaa2321b2007-03-07 00:40:28 +00008401- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008402 makes the filenames the warning module prints much more sensible
8403 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008404
Georg Brandl49aafc92007-03-07 00:34:46 +00008405- Variant of patch #697613: don't exit the interpreter on a SystemExit
8406 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008407 variable is given, but break into the interactive interpreter just
8408 like on other exceptions or normal program exit.

Georg Brandl098cd692007-03-06 12:17:50 +00008415
Georg Brandl0fca97a2007-03-05 22:28:08 +00008416- Patch #1674228: when assigning a slice (old-style), check for the
8417 sq_ass_slice instead of the sq_slice slot.
8418
Georg Brandl3ee81df2008-05-17 18:14:43 +00008419- When printing an unraisable error, don't print exceptions. before
8420 the name. This duplicates the behavior whening normally printing
8421 exceptions.
Neal Norwitz88516a62007-02-26 22:41:45 +00008422

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008922- Added a timeout parameter to the constructor of other protocols
8923 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8924 work started with create_connection() and timeout in httplib, and
8925 closes patch #723312.
8926
Vinay Sajip8549ce32007-05-06 17:53:37 +00008927- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00008953 AttributeError instead of an IOError when the server's response
8954 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00008955

Georg Brandl3ee81df2008-05-17 18:14:43 +00008960- Patch #1429539: pdb now correctly initializes the __main__ module
8961 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008962 correctly now.
8963

Georg Brandl3ee81df2008-05-17 18:14:43 +00008971- Patch #1530482: add pydoc.render_doc() which returns the

Georg Brandl9e6b4702007-03-13 18:15:41 +00008984- Patch #1581073: add a flag to textwrap that prevents the dropping of

8986
Georg Brandl92a6bae2007-03-13 17:43:32 +00008987- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008988 are set for invalid interpolation sequences that would lead to
8989 errors on reading back those values.

9032 returned string up to the first NUL character.

9043
Georg Brandl3ee81df2008-05-17 18:14:43 +00009044- unittest now verifies more of its assumptions. In particular,
9045 TestCase and TestSuite subclasses (not instances) are no longer
9046 accepted in TestSuite.addTest(). This should cause no
9047 incompatibility since it never made sense with ordinary subclasses
9048 -- the failure just occurred later, with a more cumbersome
9049 exception.

9414 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009431- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009432 time so that opening a database previously created with the DB_DUP
9433 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9434 opens. Specifically: dictionary assignment to a DB object will
9435 replace all values for a given key when the database allows
9436 duplicate values. DB users should use DB.put(k, v) when they want
9437 to store duplicates; not DB[k] = v.

9444 characters with ASCII value less than 32. Also, it correctly quotes
9445 dots only if they occur on a single line, as opposed to the previous
9446 behavior of quoting dots if they are the second character of any
9447 line.
