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 -08001577- Issue #13590: OS X Xcode 4 - improve support for universal extension modules
1578 In particular, fix extension module build failures when trying to use
1579 32-bit-only installer Pythons on systems with Xcode 4 (currently
1580 OS X 10.8, 10.7, and optionally 10.6).
1581 * Backport 3.3.0 fixes to 2.7 branch (for release in 2.7.4)
1582 * Since Xcode 4 removes ppc support, extension module builds now
1583 check for ppc compiler support and by default remove ppc and
1584 ppc64 archs when they are not available.
1585 * Extension module builds now revert to using system installed
1586 headers and libs (/usr and /System/Library) if the SDK used
1587 to build the interpreter is not installed or has moved.
1588 * Try to avoid building extension modules with deprecated
1589 and problematic Apple llvm-gcc compiler. If original compiler
1590 is not available, use clang instead by default.

2022 Distutils-based packages with C extension modules may fail because
2023 Apple has removed gcc-4.2, the version used to build python.org
2024 64-bit/32-bit Pythons. If the user does not explicitly override
2025 the default C compiler by setting the CC environment variable,
2026 Distutils will now attempt to compile extension modules with clang
2027 if gcc-4.2 is required but not found. Also as a convenience, if
2028 the user does explicitly set CC, substitute its value as the default
2029 compiler in the Distutils LDSHARED configuration variable for OS X.

Ned Deily87e82bb2011-06-28 19:52:59 -07002282- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
2283 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
2284 interpreter process. This could cause failures in non-Distutils subprocesses
2285 and was unreliable since tests or user programs could modify the interpreter
Ezio Melotti302ad8d2013-01-19 19:44:58 +02002286 environment after Distutils set it. Instead, have Distutils set the
Ned Deily87e82bb2011-06-28 19:52:59 -07002287 deployment target only in the environment of each build subprocess. It is
2288 still possible to globally override the default by setting
2289 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
2290 greater or equal to the default value, the value with which the interpreter
2291 was built.

2321 the ticker doesn't have to wind down to zero from the old starting point
2322 before the new interval takes effect. And if the user increases the
2323 interval, it makes sure the new limit takes effect right away rather have an
2324 early task switch before recognizing the new interval.

3303
Raymond Hettinger20397532010-09-12 02:11:45 +00003304- Issue #9825: removed __del__ from the definition of collections.OrderedDict.
3305 This prevents user-created self-referencing ordered dictionaries from
3306 becoming permanently uncollectable GC garbage. The downside is that
3307 removing __del__ means that the internal doubly-linked list has to wait for
3308 GC collection rather than freeing memory immediately when the refcnt drops
3309 to zero.
3310
Raymond Hettingerffd2a422010-09-10 10:47:22 +00003311- Issue #9816: random.Random.jumpahead(n) did not produce a sufficiently

3314
Antoine Pitrouc818ed42010-09-07 21:40:25 +00003315- Issue #9792: In case of connection failure, socket.create_connection()
3316 would swallow the exception and raise a new one, making it impossible
3317 to fetch the original errno, or to filter timeout errors. Now the
3318 original error is re-raised.
3319
Antoine Pitrouf4f61712010-09-07 16:34:47 +00003320- Issue #9758: When fcntl.ioctl() was called with mutable_flag set to True,

Daniel Stutzbach66c981b2010-08-31 20:29:39 +00003330- Issue #808164: Fixed socket.close to avoid references to globals, to

3339
R. David Murray7c4bf552010-08-25 01:45:57 +00003340- Issue #1194222: email.utils.parsedate now returns RFC2822 compliant four
3341 character years even if the message contains RFC822 two character years.
3342
Daniel Stutzbach91287322010-08-24 21:09:30 +00003343- Issue #8750: Fixed MutableSet's methods to correctly handle

3355 module now correctly return a set. (Patch by Eli Bendersky.)
3356
Antoine Pitrou3ebaed62010-08-21 19:17:25 +00003357- Issue #9617: Signals received during a low-level write operation aren't
3358 ignored by the buffered IO layer anymore.
3359
Benjamin Peterson52c36052010-08-21 03:03:22 +00003360- Issue #2521: Use weakrefs on for caching in the abc module, so that classes
3361 are not held onto after they are deleted elsewhere.
3362
Raymond Hettingera54b2da2010-08-17 19:03:06 +00003363- Issue #9626: the view methods for collections.OrderedDict() were returning
3364 the unordered versions inherited from dict. Those methods are now
3365 overridden to provide ordered views.

3368 comment indicating they are generated. Manually maintained MANIFESTs
3369 without this marker will not be overwritten or removed.
3370
Antoine Pitroue1436d12010-08-12 15:25:51 +00003371- Issue #7467: when reading a file from a ZIP archive, its CRC is checked
3372 and a BadZipfile error is raised if it doesn't match (as used to be the
3373 case in Python 2.5 and earlier).
3374
Antoine Pitroucb4f47c2010-08-11 13:40:17 +00003375- Issue #9550: a BufferedReader could issue an additional read when the
3376 original read request had been satisfied, which could block indefinitely
3377 when the underlying raw IO channel was e.g. a socket. Report and original
3378 patch by Jason V. Miller.
3379
Fred Drake0a1fa0e2010-08-10 13:09:54 +00003380- Issue #9551: Don't raise TypeError when setting the value to None for

3399 This is how it is supposed to work, wget and curl do the same. Previous

3772 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
3773 Previous versions returned a single u'\ufffd'.

3783 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.

4033 indefinitely if the other end didn't respond.
4034
Georg Brandlfee0f442010-05-22 21:26:21 +00004035- The do_handshake() method of SSL objects now adjusts the blocking mode of the

4154
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +00004155- Issue #8329: Don't return the same lists from select.select when no fds are
4156 changed.
4157
Georg Brandlfee0f442010-05-22 21:26:21 +00004158- Issue #8259: ``1L << (2**31)`` no longer produces an 'outrageous shift error'
Mark Dickinson82791672010-04-06 16:47:55 +00004159 on 64-bit machines. The shift count for either left or right shift is

Georg Brandlfee0f442010-05-22 21:26:21 +00004168- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
4169 with a non-empty format string. This is an effort to future-proof user
4170 code. If a derived class does not currently implement __format__ but later
4171 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00004172 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00004173 Python 3.3 and it will be an error in Python 3.4.

Georg Brandlfee0f442010-05-22 21:26:21 +00004223- Issue #7279: Comparisons involving a Decimal signaling NaN now signal
4224 InvalidOperation instead of returning False. (Comparisons involving a quiet
4225 NaN are unchanged.) Also, Decimal quiet NaNs are now hashable; Decimal
4226 signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +00004227
Georg Brandlfee0f442010-05-22 21:26:21 +00004228- Issue #2531: Comparison operations between floats and Decimal instances now
4229 return a result based on the numeric values of the operands; previously they
4230 returned an arbitrary result based on the relative ordering of id(float) and
4231 id(Decimal).

Georg Brandlfee0f442010-05-22 21:26:21 +00004245- Comparisons using one of <, <=, >, >= between a complex instance and a
4246 Fractions instance now raise TypeError instead of returning True/False. This
4247 makes Fraction <=> complex comparisons consistent with int <=> complex, float
4248 <=> complex, and complex <=> complex comparisons.

Georg Brandlba83f822010-03-14 09:50:54 +00004666 file position when calling `truncate()`. It would previously change the file
4667 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00004668 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
4669

4671 class used to represent files stored inside an archive. The new
4672 implementation is significantly faster and can be wrapped in a

4674 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

Georg Brandlba83f822010-03-14 09:50:54 +00004765- The ``__complex__()`` method is now looked up on the class of instances to
4766 make it consistent with other special methods.

4770
Mark Dickinson1b34d252010-01-01 17:27:30 +00004771- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00004772 DeprecationWarning when passed a float argument where an integer was expected.
4773 These functions and methods now raise TypeError instead. The majority of the
4774 effects of this change are in the extension modules, but some core functions
4775 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
4776 and many unicode/str methods.

Georg Brandlba83f822010-03-14 09:50:54 +00004789- Issue #1811: Improve accuracy and cross-platform consistency for true division
4790 of integers: the result of a/b is now correctly rounded for ints a and b (at
4791 least on IEEE 754 platforms), and in particular does not depend on the
4792 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00004801 These executables now work properly with the arch(1) command: ``arch -ppc
4802 python`` will start a universal binary version of python in PPC mode (unlike

Georg Brandlba83f822010-03-14 09:50:54 +00004965- Issue #7117: On almost all platforms: float-to-string and string-to-float
4966 conversions within Python are now correctly rounded. Places these conversions
4967 occur include: str for floats and complex numbers; the float and complex
4968 constructors; old-style and new-style numeric formatting; serialization and
4969 deserialization of floats and complex numbers using marshal, pickle and json;
4970 parsing of float and imaginary literals in Python code; Decimal-to-float
4971 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00004972
Georg Brandlba83f822010-03-14 09:50:54 +00004973 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
4974 providing correctly-rounded strtod and dtoa C functions. This code is
4975 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
4976 the C compiler. There may be a small number of platforms on which correct
4977 operation of this code cannot be guaranteed, so the code is not used: notably,
4978 this applies to platforms where the C double format is not IEEE 754 binary64,
4979 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
4980 and Python's configure script is unable to determine how to change the FPU
4981 precision. On these platforms conversions use the platform strtod and dtoa,
4982 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00004984- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
4985 uses the correctly-rounded string <-> float conversions described above (when
4986 available), and so produces correctly rounded results that will display nicely
4987 under the float repr. There are two related small changes: (1) round now
4988 accepts any class with an ``__index__()`` method for its second argument (but
4989 no longer accepts floats for the second argument), and (2) an excessively
4990 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
4991 raises an exception.

6576 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
6577 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
6578 neither __int__ nor __long__, TypeError used to be raised (with a
6579 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
6580 struct.error in other cases.

6583 argument with an __int__ method can be packed, but use of this feature

Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00006777- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with

6779 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
6780 ``printf`` function, whereas PyString_FromFormat has an independent

Brett Cannon1eaf0742008-09-02 01:25:16 +00006878 warnings.catch_warnings() along with some API cleanup. Expanding the tests
6879 for catch_warnings() also led to an improvement in the raising of a
6880 DeprecationWarning related to warnings.warn_explicit().

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006946What's New in Python 2.6 beta 3?
6947================================
6948
Barry Warsaw07a4a382008-08-21 01:15:08 +00006949*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00006950
6951Core and Builtins
6952-----------------
6953
Guido van Rossumf8402962008-08-20 15:01:50 +00006954- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
6955 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
6956 extensions do not automatically benefit from the class attribute
6957 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
6958 to their tp_flags field if they care. This is a backwards
6959 compatibility feature; in 3.0, all types will use the cache by
6960 default.
6961
Benjamin Petersonf647dc12008-08-20 01:27:30 +00006962- Keyword arguments can now follow starred arguments. (``f(a, *args,
6963 keyword=23)`` is now valid syntax.)
6964
Thomas Heller0ad5ae02008-08-19 19:25:04 +00006965- ctypes function pointers that are COM methods have a boolean True
6966 value again.
6967
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00006968- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
6969 by denying s# to parse objects that have a releasebuffer procedure,
6970 and introducing s*.
6971
Georg Brandl1e13ea92008-08-11 09:07:59 +00006972- Issue #3537: Fix an assertion failure when an empty but presized dict
6973 object was stored in the freelist.
6974
Mark Dickinsonb6467572008-08-04 21:30:09 +00006975- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
6976 ValueError consistently across platforms.
6977
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00006978- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
6979 (64bit Unix, for example), unichr() would truncate its argument and return
6980 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
6981
Neal Norwitze7d8be82008-07-31 17:17:14 +00006982- Apply security patches from Apple.
6983
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00006984- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
6985 PyErr_ExceptionMatches returns 0 when an exception occurs there.
6986
Antoine Pitrou92f82162008-07-25 22:22:08 +00006987- Issue #1819: function calls with several named parameters are now on
6988 average 35% faster (as measured by pybench).
6989
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00006990- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
6991 the python debugger steps into a class statement: the free variables (local
6992 variables defined in an outer scope) would be deleted from the outer scope.
6993
Gregory P. Smith0470bab2008-07-22 04:46:32 +00006994- Issue #2620: Overflow checking when allocating or reallocating memory
6995 was not always being done properly in some python types and extension
6996 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
6997 all been updated to perform better checks and places in the code that
6998 would previously leak memory on the error path when such an allocation
6999 failed have been fixed.

7002-------
7003
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00007004- Issue #3612: Added some missing basic types in ctypes.wintypes.
7005
Benjamin Petersone977ad42008-08-20 01:42:01 +00007006- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
7007 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
7008
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00007009- Issue #2234: distutils failed for some versions of the cygwin compiler. The
7010 version reported by these tools does not necessarily follow the python
7011 version numbering scheme, so the module is less strict when parsing it.
7012
Nick Coghlanf70385a2008-08-18 12:42:46 +00007013- Issue #2235: Added Py3k warnings for types which will become unhashable
7014 under the stricter __hash__ inheritance rules in 3.0. Several types
7015 which did not meet the rules for hash invariants and were already
7016 unhashable in 3.0 have now been explicitly flagged as unhashable in
7017 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
7018 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
7019
Brett Cannon88f801d2008-08-18 00:46:22 +00007020- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
7021 imported into the module but exposed as part of the module's API.
7022
Brett Cannon7b96f072008-08-18 00:41:11 +00007023- Remove an unneeded import of abc.ABCMeta from 'inspect'.
7024
Brett Cannon46225e72008-08-18 00:36:52 +00007025- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00007027- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
7028
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00007029- Issue #3575: Incremental decoder's decode function now takes bytearray
7030 by using 's*' instead of 't#'.
7031
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00007032- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00007033 fails unicode conversion on 2nd parameter. (windows only)
7034
Georg Brandl222e2082010-08-01 22:27:39 +00007035- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00007036 in a redirect.
7037
Brett Cannonabe423e2008-08-16 21:47:07 +00007038- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00007039 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00007040
Facundo Batistaeb90b782008-08-16 14:44:07 +00007041- Issue #2776: fixed small issue when handling an URL with double slash
7042 after a 302 response in the case of not going through a proxy.
7043
Antoine Pitroub90a8be2008-08-15 21:03:21 +00007044- Issue #2676: in the email package, content-type parsing was hanging on
7045 pathological input because of quadratic or exponential behaviour of a
7046 regular expression.
7047
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00007048- Issue #3476: binary buffered reading through the new "io" library is now
7049 thread-safe.
7050
Brett Cannonbf3157b2008-08-14 05:00:03 +00007051- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
7052 since mimetools itself is deprecated. Because modules are cached, all
7053 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
7054
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00007055- Issue #3134: shutil referenced undefined WindowsError symbol.
7056
Robert Schuppenies14646332008-08-10 11:01:53 +00007057- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
7058 menu entries were not deleted.
7059
Brett Cannon83e81842008-08-09 23:30:55 +00007060- Copied the implementation of reduce() to _functools.reduce() to have a
7061 version that did not raise a DeprecationWarning under -3.
7062
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00007063- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
7064 a MemoryError rather than silently stop the iteration.
7065
Guido van Rossum59ce9012008-08-09 14:55:34 +00007066- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
7067 to _sre.compile() will now be rejected. This should not affect anybody
7068 since the re.compile() function never generates invalid re-bytecode.
7069
Skip Montanaroa032bf42008-08-08 22:52:51 +00007070- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
7071 upon first access it can be automatically initialized from the csv file if
7072 it wasn't initialized during instantiation.
7073
Brett Cannon3aa2a492008-08-06 22:28:09 +00007074- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
7075 the reload() built-in has been removed.
7076
Brett Cannon7e30b672008-08-04 21:52:25 +00007077- Changed code in the following modules/packages to remove warnings raised
Brett Cannonc1b76e42008-08-09 23:06:16 +00007078 while running under the ``-3`` flag: aifc, asynchat, asyncore, bdb, bsddb,

Antoine Pitroude781a42008-08-09 12:43:23 +00007089 asking for a specific length. This problem only affected files opened
7090 using the new "io" module, not the built-in open() function.
Benjamin Peterson01a24322008-07-28 23:35:27 +00007091
Mark Dickinsonfe84cce2008-07-27 06:39:07 +00007092- Issue #3449: Update decimal module to use most recent specification
7093 (v. 1.68) and tests (v. 2.58) from IBM.

7142
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00007143*Release date: 17-Jul-2008*

7146-----------------
7147
Georg Brandl3e483f62008-07-16 22:57:41 +00007148- Issue #3156: Fix inconsistent behavior of the bytearray type: all
7149 its methods now allow for items objects that can be converted to
7150 an integer using operator.index().
7151
Mark Dickinson64b7e502008-07-16 09:40:03 +00007152- Issue #3360: Fix incorrect parsing of '020000000000.0', which
7153 produced a ValueError instead of giving the correct float.
7154
Eric Smitha5fa5a22008-07-16 00:11:49 +00007155- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
7156 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
7157
Mark Dickinson7103aa42008-07-15 19:08:33 +00007158- Issue #3008: the float type has a new instance method 'float.hex'
7159 and a new class method 'float.fromhex' to convert floating-point
7160 numbers to and from hexadecimal strings, respectively.
7161
Nick Coghlan6d6bd442008-07-15 15:40:22 +00007162- Issue #2235: __hash__ is once again inherited by default. To allow
7163 collections.Hashable to remain meaningful in the presence of the
7164 default hash implementation (object.__hash__), it is now possible
7165 to explicit block inheritance of hash by setting __hash__=None at
7166 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
7167 level.
7168
Nick Coghlanb028f502008-07-13 14:52:36 +00007169- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
7170 the parent module cannot be found while performing an absolute import.
7171 This means that an incorrectly defined __package__ attribute will
7172 now only prevent relative imports in that module rather than causing
7173 all imports from that module to fail.
7174
Nick Coghlan14ff9942008-07-08 14:21:42 +00007175- Issue #2517: Allow unicode messages in Exceptions again by correctly

7184 threading.local: the first member set by a thread could be saved in
7185 another thread's dictionary.
7186
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00007187- Issue #3004: Minor change to slice.indices(): the start and stop
7188 arguments are now treated identically, making the behaviour easier
7189 to describe and understand. For example, slice(None, -10,
7190 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
7191 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
7192 10, -1).
7193
Georg Brandl278fc502008-07-19 12:46:12 +00007194- Issue #3219: Calling a function with repeated keyword arguments,
7195 f(a=2, a=23), would not cause a syntax error. This was a regression
7196 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00007197
Georg Brandl278fc502008-07-19 12:46:12 +00007198- Issue #2862: Make int and float freelist management consistent with
7199 other freelists. Changes their CompactFreeList apis into
7200 ClearFreeList apis and calls them via gc.collect().

7206 api functions without holding the GIL, which could lead to a fatal
7207 error when they failed.
7208
Martin v. Löwisaabf4042008-08-02 07:20:25 +00007209- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007234- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
7235 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00007236 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00007237 content-length. The problem had been corrected in the 2.4 branch, but never
7238 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00007253- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

Georg Brandl3ee81df2008-05-17 18:14:43 +00007705- Issue #1631171: Re-implement the 'warnings' module in C (the
7706 original Python code has been kept as backup). This will allow for
7707 using the 'warning's machinery in such places as the parser where
7708 use of pure Python code is not possible. Both the ``showarning()``
7709 and ``formatwarning()`` gain an optional 'line' argument which is
7710 not called by default for backwards-compatibility reasons. Setting
7711 ``warnings.showwarning()`` to an implementation that lacks support
7712 for the ``line`` argument will raise a DeprecationWarning.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007775- Issue #2550: The approach used by client/server code for obtaining
7776 ports to listen on in network-oriented tests has been refined in an
7777 effort to facilitate running multiple instances of the entire
7778 regression test suite in parallel without issue.
7779 test_support.bind_port() has been fixed such that it will always
7780 return a unique port -- which wasn't always the case with the
7781 previous implementation, especially if socket options had been set
7782 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
7783 new implementation of bind_port() will actually raise an exception
7784 if it is passed an AF_INET/SOCK_STREAM socket with either the
7785 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
7786 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
7787 the socket it's been passed. This currently only applies to
7788 Windows. This option prevents any other sockets from binding to the
7789 host/port we've bound to, thus removing the possibility of the
7790 'non-deterministic' behaviour, as Microsoft puts it, that occurs
7791 when a second SOCK_STREAM socket binds and accepts to a host/port
7792 that's already been bound by another socket. The optional preferred
7793 port parameter to bind_port() has been removed. Under no
7794 circumstances should tests be hard coding ports!
7795
7796 test_support.find_unused_port() has also been introduced, which will
7797 pass a temporary socket object to bind_port() in order to obtain an
7798 unused port. The temporary socket object is then closed and
7799 deleted, and the port is returned. This method should only be used
7800 for obtaining an unused port in order to pass to an external program
7801 (i.e. the -accept [port] argument to openssl's s_server mode) or as
7802 a parameter to a server-oriented class that doesn't give you direct
7803 access to the underlying socket used.
7804
7805 Finally, test_support.HOST has been introduced, which should be used
7806 for the host argument of any relevant socket calls (i.e. bind and
7807 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00007808
7809 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00007810 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00007811 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
7812 test_asynchat and test_socket_ssl.
7813
Georg Brandl3ee81df2008-05-17 18:14:43 +00007814 It is now possible for multiple instances of the regression test
7815 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00008094- Added the future_builtins module, which contains hex() and oct().
8095 These are the PEP 3127 version of these functions, designed to be
8096 compatible with the hex() and oct() builtins from Python 3.0. They
8097 differ slightly in their output formats from the existing, unchanged
8098 Python 2.6 builtins. The expected usage of the future_builtins
8099 module is:
8100 from future_builtins import hex, oct
8101
Eric Smith7ef40bf2008-02-20 23:34:22 +00008102- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
8103 exponents for exponents with absolute value < 100. Follows C99
8104 standard. This is a change on Windows, which would use 3 digits.
8105 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
8106 so that any alterations it does to the resulting string will be
8107 available in stringlib/formatter.h (for float.__format__).
8108
Eric Smith5a3c1352008-02-19 13:21:56 +00008109- Implemented PEP 3101, Advanced String Formatting. This adds a new
8110 builtin format(); a format() method for str and unicode; a
8111 __format__() method to object, str, unicode, int, long, float, and
8112 datetime; the class string.Formatter; and the C API
8113 PyObject_Format().
8114
Georg Brandl3ee81df2008-05-17 18:14:43 +00008115- Fixed several potential crashes, all caused by specially crafted
8116 __del__ methods exploiting objects in temporarily inconsistent
8117 state.

8127 in order to allow pymalloc to free more arenas. Python may give back
8128 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00008129
Georg Brandl3ee81df2008-05-17 18:14:43 +00008130- Issue #2045: Fix an infinite recursion triggered when printing a
8131 subclass of collections.defaultdict, if its default_factory is set
8132 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00008133
Christian Heimesf75dbef2008-02-08 00:11:31 +00008134- Fixed a minor memory leak in dictobject.c. The content of the free

8141 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00008142 to compact the internal free lists of pre-allocted ints and floats.
8143
Georg Brandl3ee81df2008-05-17 18:14:43 +00008144- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
8145 calls. Python expected the return type int but the fork familie
8146 returns pi_t.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008160- Patch #1473257: generator objects gain a gi_code attribute. This is
8161 the same object as the func_code attribute of the function that
8162 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00008163
Georg Brandl3ee81df2008-05-17 18:14:43 +00008164- Issue #1920: "while 0" statements were completely removed by the
8165 compiler, even in the presence of an "else" clause, which is
8166 supposed to be run when the condition is false. Now the compiler
8167 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00008168

8185
Georg Brandl6caad7d2008-01-26 14:19:22 +00008186- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00008187 added.
8188
Christian Heimesc94e2b52008-01-14 04:13:37 +00008189- sys.float_info / PyFloat_GetInfo: The floating point information
8190 object was converted from a dict to a specialized structseq object.
8191
Georg Brandl3ee81df2008-05-17 18:14:43 +00008192- Patch #1816: Added sys.flags structseq. It exposes the status of
8193 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00008194
Georg Brandl3ee81df2008-05-17 18:14:43 +00008195- Objects/structseq.c: Implemented new structseq representation. The
8196 patch makes structseqs (e.g. the return value of os.stat) more
8197 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00008198
Georg Brandl3ee81df2008-05-17 18:14:43 +00008199- Patch #1700288: added a type attribute cache that caches method
8200 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00008201
Neal Norwitz3fc15b82008-01-10 05:42:58 +00008202- Bug #1776: __import__() no longer accepts filenames on any platform.
8203 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00008204
Georg Brandlaed6c662008-01-07 17:25:53 +00008205- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
8206
Georg Brandl3ee81df2008-05-17 18:14:43 +00008207- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
8208 envvar and sys.dont_write_bytecode attribute. All these can be set
8209 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00008210
Georg Brandl3ee81df2008-05-17 18:14:43 +00008211- Improve some exception messages when Windows fails to load an
8212 extension module. Now we get for example '%1 is not a valid Win32
8213 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00008214

8218 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00008219
Christian Heimes0a8143f2007-12-18 23:22:54 +00008220- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00008221 and INF. float("nan"), float("inf") and float("-inf") now work on
8222 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00008223
Georg Brandl3ee81df2008-05-17 18:14:43 +00008224- Compiler now generates simpler and faster code for dictionary
8225 literals. The oparg for BUILD_MAP now indicates an estimated
8226 dictionary size. There is a new opcode, STORE_MAP, for adding
8227 entries to the dictionary.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008256- Patch #1739468: Directories and zipfiles containing a __main__.py
8257 file can now be directly executed by passing their name to the
8258 interpreter. The directory/zipfile is automatically inserted as the
8259 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00008260
Georg Brandl3ee81df2008-05-17 18:14:43 +00008261- Issue #1265: Fix a problem with sys.settrace, if the tracing
8262 function uses a generator expression when at the same time the
8263 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00008264
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00008265- sets and frozensets now have an isdisjoint() method.
8266
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00008267- optimize the performance of builtin.sum().
8268
Neal Norwitz44f326e2007-10-05 05:29:17 +00008269- Fix warnings found by the new version of the Coverity checker.
8270
Georg Brandl21e99f42010-03-07 15:23:59 +00008271- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00008272 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
8273 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00008274
Georg Brandl3ee81df2008-05-17 18:14:43 +00008275- Issue #1686386: Tuple's tp_repr did not take into account the
8276 possibility of having a self-referential tuple, which is possible
8277 from C code. Nor did object's tp_str consider that a type's tp_str
8278 could do something that could lead to an inifinite recursion.
8279 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
8280 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00008281
Georg Brandl3ee81df2008-05-17 18:14:43 +00008282- Issue #1164: It was possible to trigger deadlock when using the
8283 'print' statement to write to a file since the GIL was not released
8284 as needed. Now PyObject_Print() does the right thing along with
8285 various tp_print implementations of the built-in types and those in
8286 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00008287
Georg Brandl3ee81df2008-05-17 18:14:43 +00008288- Issue #1147: Exceptions were directly allowing string exceptions in
8289 their throw() method even though string exceptions no longer
8290 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00008291
Georg Brandl3ee81df2008-05-17 18:14:43 +00008292- Issue #1096: Prevent a segfault from getting the repr of a very
8293 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00008294
Brett Cannon1e534b52007-09-07 04:18:30 +00008295- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00008296 PyObject_Call() never calling back out to Python code to trigger
8297 recursion depth updates/checks. Required the creation of a static
8298 RuntimeError instance in case normalizing an exception put the
8299 recursion check value past its limit. Fixes crashers
8300 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00008301
Georg Brandl3ee81df2008-05-17 18:14:43 +00008302- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00008315- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00008316 __*__ attributes. (Some already existed, e.g., __doc__ and
8317 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00008318
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00008319- Add -3 option to the interpreter to warn about features that are
8320 deprecated and will be changed/removed in Python 3.0.
8321
Georg Brandl2134e752007-05-21 20:34:16 +00008322- Patch #1686487: you can now pass any mapping after '**' in function
8323 calls.
8324
Collin Winter62903052007-05-18 23:11:24 +00008325- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00008326 "except E as target:". This is to provide forwards compatibility
8327 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00008328
Brett Cannon229cee22007-05-05 01:34:02 +00008329- Deprecate BaseException.message as per PEP 352.
8330
Georg Brandl3ee81df2008-05-17 18:14:43 +00008331- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00008332 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00008333
Vinay Sajip8549ce32007-05-06 17:53:37 +00008334- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00008335 setting a plain string, ie don't expand to single letter identifiers.
8336
Raymond Hettinger13936692007-04-11 18:40:58 +00008337- Request #1191699: Slices can now be pickled.
8338
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00008339- Request #1193128: str.translate() now allows a None argument for
8340 translations that only remove characters without re-mapping the
8341 remaining characters.
8342
Georg Brandl5cb76c12007-03-21 09:00:39 +00008343- Patch #1682205: a TypeError while unpacking an iterable is no longer
8344 masked by a generic one with the message "unpack non-sequence".
8345
Neal Norwitzaa754b72007-03-21 06:39:48 +00008346- Remove unused file Python/fmod.c.
8347
Guido van Rossum143b5642007-03-23 04:58:42 +00008348- Bug #1683368: The object.__init__() and object.__new__() methods are
8349 now stricter in rejecting excess arguments. The only time when
8350 either allows excess arguments is when it is not overridden and the
8351 other one is. For backwards compatibility, when both are
8352 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00008353 warning later). Also, type.__init__() insists on the same signature
8354 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00008355
Georg Brandl3ee81df2008-05-17 18:14:43 +00008356- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
8357 object to complex using its __complex__() method before falling back
8358 to the __float__() method. Therefore, the functions in the cmath
8359 module now can operate on objects that define a __complex__()
8360 method.
Georg Brandl2b869942007-03-17 16:08:45 +00008361
Georg Brandl3ee81df2008-05-17 18:14:43 +00008362- Patch #1623563: allow __class__ assignment for classes with
8363 __slots__. The old and the new class are still required to have the
8364 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00008365
Georg Brandl3ee81df2008-05-17 18:14:43 +00008366- Patch #1642547: Fix an error/crash when encountering syntax errors

8370 ``object.__reduce_ex__()`` is called with an object that is faking
8371 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00008372
Georg Brandl3ee81df2008-05-17 18:14:43 +00008373- Patch #1680015: Don't modify __slots__ tuple if it contains an

8377
Georg Brandl7b9c5552007-03-12 14:30:05 +00008378- Bug #1678647: write a newline after printing an exception in any
8379 case, even when converting the value to a string failed.
8380
Georg Brandl871f1bc2007-03-12 13:17:36 +00008381- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00008382 its argument, if it exists. If not, it will work like before. This
8383 allows customizing the output of dir() in the presence of a
8384 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00008385
Collin Winter276887b2007-03-12 16:11:39 +00008386- Patch #922167: Python no longer segfaults when faced with infinitely
8387 self-recursive reload() calls (as reported by bug #742342).
8388
Georg Brandl3ee81df2008-05-17 18:14:43 +00008389- Patch #1675981: remove unreachable code from ``type.__new__()``

Georg Brandl3ee81df2008-05-17 18:14:43 +00008392- Patch #1491866: change the complex() constructor to allow
8393 parthensized forms. This means complex(repr(x)) now works instead of
8394 raising a ValueError.
Collin Wintere38051d2007-03-09 20:33:07 +00008395
Georg Brandlaa2321b2007-03-07 00:40:28 +00008396- Patch #703779: unset __file__ in __main__ after running a file. This
Georg Brandl3ee81df2008-05-17 18:14:43 +00008397 makes the filenames the warning module prints much more sensible
8398 when a PYTHONSTARTUP file is used.
Georg Brandlaa2321b2007-03-07 00:40:28 +00008399
Georg Brandl49aafc92007-03-07 00:34:46 +00008400- Variant of patch #697613: don't exit the interpreter on a SystemExit
8401 exception if the -i command line option or PYTHONINSPECT environment
Georg Brandl3ee81df2008-05-17 18:14:43 +00008402 variable is given, but break into the interactive interpreter just
8403 like on other exceptions or normal program exit.

Georg Brandl0fca97a2007-03-05 22:28:08 +00008411- Patch #1674228: when assigning a slice (old-style), check for the
8412 sq_ass_slice instead of the sq_slice slot.
8413
Georg Brandl3ee81df2008-05-17 18:14:43 +00008414- When printing an unraisable error, don't print exceptions. before
8415 the name. This duplicates the behavior whening normally printing
8416 exceptions.

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00008917- Added a timeout parameter to the constructor of other protocols
8918 (telnetlib, ftplib, smtplib and poplib). This is second part of the
8919 work started with create_connection() and timeout in httplib, and

Georg Brandl3ee81df2008-05-17 18:14:43 +00008948 AttributeError instead of an IOError when the server's response
8949 didn't contain a valid HTTP status line.

Georg Brandl3ee81df2008-05-17 18:14:43 +00008955- Patch #1429539: pdb now correctly initializes the __main__ module
8956 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00008957 correctly now.
8958

Georg Brandl3ee81df2008-05-17 18:14:43 +00008966- Patch #1530482: add pydoc.render_doc() which returns the

8981
Georg Brandl92a6bae2007-03-13 17:43:32 +00008982- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00008983 are set for invalid interpolation sequences that would lead to
8984 errors on reading back those values.

9027 returned string up to the first NUL character.

9038
Georg Brandl3ee81df2008-05-17 18:14:43 +00009039- unittest now verifies more of its assumptions. In particular,
9040 TestCase and TestSuite subclasses (not instances) are no longer
9041 accepted in TestSuite.addTest(). This should cause no
9042 incompatibility since it never made sense with ordinary subclasses
9043 -- the failure just occurred later, with a more cumbersome
9044 exception.

9054
Georg Brandl3ee81df2008-05-17 18:14:43 +00009055- Patch #1673619: setup.py identifies extension modules it doesn't

9409 complex, tuple, list, dict, set, and frozenset. Formerly, it would

Gregory P. Smithec10a4a2007-11-05 02:32:26 +00009426- pybsddb.sf.net Bug #477182: Load the database flags at database open
Georg Brandl3ee81df2008-05-17 18:14:43 +00009427 time so that opening a database previously created with the DB_DUP
9428 or DB_DUPSORT flag set will keep the proper behavior on subsequent
9429 opens. Specifically: dictionary assignment to a DB object will
9430 replace all values for a given key when the database allows
9431 duplicate values. DB users should use DB.put(k, v) when they want
9432 to store duplicates; not DB[k] = v.

9439 characters with ASCII value less than 32. Also, it correctly quotes
9440 dots only if they occur on a single line, as opposed to the previous
9441 behavior of quoting dots if they are the second character of any
9442 line.
