Florent Xiclunac2279652012-02-12 14:49:03 +0100346- Issue #13994: Earlier partial revert of Distutils enhancements in 2.7
Ned Deilyc47a4592012-02-11 20:40:24 +0100347 has left two versions of customize_compiler, the original in
348 distutils.sysconfig and another copy in distutils.ccompiler, with some
349 parts of distutils calling one and others using the other.
350 Complete the revert back to only having one in distutils.sysconfig as
351 is the case in 3.x.
352
Ned Deily0d0ea482012-02-10 12:59:06 +0100353- Issue #13590: On OS X 10.7 and 10.6 with Xcode 4.2, building
354 Distutils-based packages with C extension modules may fail because
355 Apple has removed gcc-4.2, the version used to build python.org
356 64-bit/32-bit Pythons. If the user does not explicitly override
357 the default C compiler by setting the CC environment variable,
358 Distutils will now attempt to compile extension modules with clang
359 if gcc-4.2 is required but not found. Also as a convenience, if
360 the user does explicitly set CC, substitute its value as the default
361 compiler in the Distutils LDSHARED configuration variable for OS X.
362 (Note, the python.org 32-bit-only Pythons use gcc-4.0 and the 10.4u
363 SDK, neither of which are available in Xcode 4. This change does not
364 attempt to override settings to support their use with Xcode 4.)

Ned Deily87e82bb2011-06-28 19:52:59 -0700637- Issue #9516: On Mac OS X, change Distutils to no longer globally attempt to
638 check or set the MACOSX_DEPLOYMENT_TARGET environment variable for the
639 interpreter process. This could cause failures in non-Distutils subprocesses
640 and was unreliable since tests or user programs could modify the interpreter
641 environment after Distutils set it. Instead, have Distutils set the the
642 deployment target only in the environment of each build subprocess. It is
643 still possible to globally override the default by setting
644 MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
645 greater or equal to the default value, the value with which the interpreter
646 was built.

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

1624 This prevents user-created self-referencing ordered dictionaries from
1625 becoming permanently uncollectable GC garbage. The downside is that

2085-----------------
2086
Ezio Melottiab2eb0e2010-06-05 19:21:32 +00002087- Issue #8271: during the decoding of an invalid UTF-8 byte sequence, only the
2088 start byte and the continuation byte(s) are now considered invalid, instead
2089 of the number of bytes specified by the start byte.
2090 E.g.: '\xf1\x80AB'.decode('utf-8', 'replace') now returns u'\ufffdAB' and
2091 replaces with U+FFFD only the start byte ('\xf1') and the continuation byte
2092 ('\x80') even if '\xf1' is the start byte of a 4-bytes sequence.
2093 Previous versions returned a single u'\ufffd'.
2094
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002095- Issue #8627: Remove bogus "Overriding __cmp__ blocks inheritance of
Mark Dickinsone4b83e02010-06-05 12:14:43 +00002096 __hash__ in 3.x" warning. Also fix "XXX undetected error" that
2097 arises from the "Overriding __eq__ blocks inheritance ..." warning
2098 when turned into an exception: in this case the exception simply
2099 gets ignored.
Mark Dickinson23f0d6b2010-06-05 11:52:24 +00002100
Mark Dickinson4ca7c3c2010-05-30 13:18:10 +00002101- Issue #8748: Fix two issues with comparisons between complex and integer
2102 objects. (1) The comparison could incorrectly return True in some cases
2103 (2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
2104 (2) The comparison raised an OverflowError for large integers, leading
2105 to unpredictable exceptions when combining integers and complex objects
2106 in sets or dicts.
2107
Mark Dickinson81336372010-05-30 12:12:25 +00002108- Issue #5211: Implicit coercion for the complex type is now completely
2109 removed. (Coercion for arithmetic operations was already removed in 2.7
2110 alpha 4, but coercion for rich comparisons was accidentally left in.)
2111
Victor Stinnerc49dfcc2010-05-25 22:30:32 +00002112- Issue #3798: Write sys.exit() message to sys.stderr to use stderr encoding
2113 and error handler, instead of writing to the C stderr file in utf-8
2114
Georg Brandlfee0f442010-05-22 21:26:21 +00002115- Issue #7902: When using explicit relative import syntax, don't try implicit
2116 relative import semantics.

Georg Brandlfee0f442010-05-22 21:26:21 +00002488- Issue #7994: Issue a PendingDeprecationWarning if object.__format__ is called
2489 with a non-empty format string. This is an effort to future-proof user
2490 code. If a derived class does not currently implement __format__ but later
2491 adds its own __format__, it would most likely break user code that had
Antoine Pitrou01a196a2011-01-02 20:05:11 +00002492 supplied a format string. This will be changed to a DeprecationWarning in
Georg Brandlfee0f442010-05-22 21:26:21 +00002493 Python 3.3 and it will be an error in Python 3.4.

Barry Warsawf7f2d6f2010-03-31 21:07:16 +00002553- Issue #8233: When run as a script, py_compile.py optionally takes a single
Georg Brandlfee0f442010-05-22 21:26:21 +00002554 argument `-` which tells it to read files to compile from stdin. Each line is
2555 read on demand and the named file is compiled immediately. (Original patch by
2556 Piotr Ożarowski).

Georg Brandlba83f822010-03-14 09:50:54 +00002930- Issue #7561: Operations on empty bytearrays (such as ``int(bytearray())``)
2931 could crash in many places because of the ``PyByteArray_AS_STRING()`` macro
2932 returning NULL. The macro now returns a statically allocated empty string
2933 instead.

2943 strings,
2944 (2) a crash in dtoa.c that occurred in debug builds when parsing certain long
2945 numeric strings corresponding to subnormal values,
2946 (3) a memory leak for some values large enough to cause overflow, and
2947 (4) a number of flaws that could lead to incorrectly rounded results.

2966
Georg Brandlba83f822010-03-14 09:50:54 +00002967- Issue #2746: Don't escape ampersands and angle brackets ("&", "<", ">") in

Antoine Pitroud840e512010-02-04 20:20:18 +00002978- Issue #4772: Raise a ValueError when an unknown Bluetooth protocol is
Georg Brandlba83f822010-03-14 09:50:54 +00002979 specified, rather than fall through to AF_PACKET (in the ``socket`` module).
Antoine Pitroud840e512010-02-04 20:20:18 +00002980 Also, raise ValueError rather than TypeError when an unknown TIPC address
2981 type is specified. Patch by Brian Curtin.

Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002985- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +00002986 file position when calling `truncate()`. It would previously change the file
2987 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +00002988 ftruncate() and other truncation APIs. Patch by Pascal Chambon.
2989
Georg Brandlba83f822010-03-14 09:50:54 +00002990- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
2991 class used to represent files stored inside an archive. The new
2992 implementation is significantly faster and can be wrapped in a
2993 ``io.BufferedReader`` object for more speedups. It also solves an issue
2994 where interleaved calls to ``read()`` and ``readline()`` give wrong results.
2995 Patch by Nir Aides.

Georg Brandlba83f822010-03-14 09:50:54 +00003005- Issue #7748: Since unicode values are supported for some metadata options in
3006 Distutils, the DistributionMetadata get_* methods will now return an utf-8
3007 encoded string for them. This ensures that the upload and register commands
3008 send the correct values to PyPI without any error.

3084
Georg Brandlba83f822010-03-14 09:50:54 +00003085- The ``__complex__()`` method is now looked up on the class of instances to

3090
Mark Dickinson1b34d252010-01-01 17:27:30 +00003091- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +00003092 DeprecationWarning when passed a float argument where an integer was expected.
3093 These functions and methods now raise TypeError instead. The majority of the
3094 effects of this change are in the extension modules, but some core functions
3095 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
3096 and many unicode/str methods.

3112 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +00003279- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
3280 decimal string that's guaranteed to round back to x under correct rounding
3281 (with round-half-to-even rounding mode). Previously it gave a string based on
3282 rounding x to 17 decimal digits. repr(x) for a complex number behaves
3283 similarly. On platforms where the correctly-rounded strtod and dtoa code is
3284 not supported (see below), repr is unchanged.

Georg Brandlba83f822010-03-14 09:50:54 +00003286- Issue #7117: On almost all platforms: float-to-string and string-to-float
3287 conversions within Python are now correctly rounded. Places these conversions
3288 occur include: str for floats and complex numbers; the float and complex
3289 constructors; old-style and new-style numeric formatting; serialization and
3290 deserialization of floats and complex numbers using marshal, pickle and json;
3291 parsing of float and imaginary literals in Python code; Decimal-to-float
3292 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +00003293
Georg Brandlba83f822010-03-14 09:50:54 +00003294 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
3295 providing correctly-rounded strtod and dtoa C functions. This code is
3296 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
3297 the C compiler. There may be a small number of platforms on which correct
3298 operation of this code cannot be guaranteed, so the code is not used: notably,
3299 this applies to platforms where the C double format is not IEEE 754 binary64,
3300 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
3301 and Python's configure script is unable to determine how to change the FPU
3302 precision. On these platforms conversions use the platform strtod and dtoa,
3303 as before.

Georg Brandlba83f822010-03-14 09:50:54 +00003305- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
3306 uses the correctly-rounded string <-> float conversions described above (when
3307 available), and so produces correctly rounded results that will display nicely
3308 under the float repr. There are two related small changes: (1) round now
3309 accepts any class with an ``__index__()`` method for its second argument (but
3310 no longer accepts floats for the second argument), and (2) an excessively
3311 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
3312 raises an exception.

4882 integer format code ('bBhHiIlLqQ'). Packing an out-of-range integer now
4883 consistently raises struct.error.
Mark Dickinson5fd3af22009-07-07 15:08:28 +00004884
Georg Brandlba83f822010-03-14 09:50:54 +00004885- Issues #1530559, #1741130: Fix various struct.pack inconsistencies for the

Georg Brandlba83f822010-03-14 09:50:54 +00004889 - Packing a float now always gives a Deprecation Warning. Previously it
4890 only warned for 'I', 'L', '*B', '*H', '*I', '*L'.
Mark Dickinson463dc4b2009-07-05 10:01:24 +00004891
Georg Brandlba83f822010-03-14 09:50:54 +00004892 - If x is not an int, long or float, then packing x will always result in
4893 struct.error. Previously an x with an __int__ method could be packed by
4894 'b', 'B', 'h', 'H', 'i', 'l', '*b', '*h' ,'*i', '*l', and an x with a
4895 __long__ method could be packed by 'q', 'Q', '*q', '*Q'; for x with
4896 neither __int__ nor __long__, TypeError used to be raised (with a
4897 confusing error message) for 'I', 'L', '*B', '*H', '*I', '*L', and
4898 struct.error in other cases.

Georg Brandlba83f822010-03-14 09:50:54 +00004900 Note: as of Python 2.7 beta 1, the above is out of date. In 2.7 beta 1, any
4901 argument with an __int__ method can be packed, but use of this feature
4902 triggers a DeprecationWarning.

Georg Brandlba83f822010-03-14 09:50:54 +00004935- Issue #7431: Use TESTFN in test_linecache instead of trying to create a file
4936 in the Lib/test directory, which might be read-only for the user running the
4937 tests.
R. David Murray820b0ea2009-12-03 23:57:59 +00004938
Georg Brandlba83f822010-03-14 09:50:54 +00004939- Issue #7324: Add a sanity check to regrtest argument parsing to catch the case
4940 of an option with no handler.
R. David Murrayda826892009-11-15 00:04:32 +00004941
Georg Brandlba83f822010-03-14 09:50:54 +00004942- Issue #7312: Add a -F flag to run the selected tests in a loop until a test
4943 fails. Can be combined with -j.
R. David Murray7f7eea62009-11-14 15:18:22 +00004944
Antoine Pitrou310c9fe2009-11-11 20:55:07 +00004945- Issue #7295: Do not use a hardcoded file name in test_tarfile.

Antoine Pitrouc98efe02009-11-06 22:34:35 +00004947- Issue #7270: Add some dedicated unit tests for multi-thread synchronization
4948 primitives such as Lock, RLock, Condition, Event and Semaphore.
4949
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004950- Issue #7222: Make thread "reaping" more reliable so that reference
Georg Brandlba83f822010-03-14 09:50:54 +00004951 leak-chasing test runs give sensible results. The previous method of reaping
4952 threads could return successfully while some Thread objects were still
4953 referenced. This also introduces a new private function: ``thread._count()``.
Antoine Pitrou59c44f32009-10-30 17:07:08 +00004954
Georg Brandlba83f822010-03-14 09:50:54 +00004955- Issue #7151: Fixed regrtest -j so that output to stderr from a test no longer
4956 runs the risk of causing the worker thread to fail.
R. David Murray282396f2009-10-18 21:12:37 +00004957
Antoine Pitrou58d2f262009-10-10 20:52:11 +00004958- Issue #7055: test___all__ now greedily detects all modules which have an
4959 __all__ attribute, rather than using a hardcoded and incomplete list.
4960
R. David Murray14dcd432009-10-14 13:58:07 +00004961- Issue #7058: Added save/restore for things like sys.argv and cwd to
4962 runtest_inner in regrtest, with warnings if the called test modifies them,
4963 and a new section in the summary report at the end.
R. David Murrayabe3d3e2009-10-05 17:03:09 +00004964
Mark Dickinson245d9152009-10-04 18:38:39 +00004965- Issue #7042: Fix test_signal (test_itimer_virtual) failure on OS X 10.6.

4968 off the trailing 0 in the version number.
4969
Guilherme Polo7f146ab2009-06-21 17:22:50 +00004970- Issue #5450: Moved tests involving loading tk from Lib/test/test_tcl to
4971 Lib/lib-tk/test/test_tkinter/test_loadtk. With this, these tests demonstrate
Georg Brandlba83f822010-03-14 09:50:54 +00004972 the same behaviour as test_ttkguionly (and now also test_tk) which is to skip
4973 the tests if DISPLAY is defined but can't be used.
Guilherme Polo7f146ab2009-06-21 17:22:50 +00004974
Antoine Pitrou4698d992009-05-31 14:20:14 +00004975- Issue #6152: New option '-j'/'--multiprocess' for regrtest allows running
4976 regression tests in parallel, shortening the total runtime.
4977
Georg Brandlba83f822010-03-14 09:50:54 +00004978- Issue #5354: New test support function import_fresh_module() makes it easy to
4979 import both normal and optimised versions of modules. test_heapq and
4980 test_warnings have been adjusted to use it, tests for other modules with both
4981 C and Python implementations in the stdlib can be adjusted to use it over
4982 time.

4989
Georg Brandlba83f822010-03-14 09:50:54 +00004990- regrtest no longer treats ImportError as equivalent to SkipTest. Imports that
4991 should cause a test to be skipped are now done using import_module from test
4992 support, which does the conversion.
R. David Murray41448c52009-03-31 19:57:24 +00004993
Guilherme Polob1a98de2009-01-28 20:03:26 +00004994- Issue #5083: New 'gui' resource for regrtest.

5094
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00005095- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
5096 PyString_FromFormat or PyErr_Format to display size_t values. The macro
5097 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
5098 ``printf`` function, whereas PyString_FromFormat has an independent
5099 implementation and uses "%zd" on all platforms for size_t values.
5100 This makes a difference on win64, where ``printf`` needs "%Id" to display
5101 64bit values.

Benjamin Peterson97179b02008-09-09 20:55:01 +00005103- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on

5115
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005116- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00005117 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00005118 was correctly parsed but parsing of subsequent arguments failed.
5119
Vinay Sajip35e3b032008-09-01 14:33:59 +00005120- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00005121 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
5122 mechanism. In the process, fix a bug where isinstance() and issubclass(),
5123 when given a tuple of classes as second argument, were looking up
5124 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
5125 type object.
5126
Neal Norwitz18aa3882008-08-24 05:04:52 +00005127- Fix crashes on memory allocation failure found with failmalloc.

5136 function 'stringlib_contains_obj'.
5137
Benjamin Peterson712ee922008-08-24 18:10:20 +00005138- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
5139 ``__delslice__``.

5142 library targets in the Makefile.
5143
Gregory P. Smith980b99b2008-09-07 05:15:18 +00005144- Issue #1204: The configure script now tests for additional libraries
5145 that may be required when linking against readline. This fixes issues
5146 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

Brett Cannon1eaf0742008-09-02 01:25:16 +00005196 warnings.catch_warnings() along with some API cleanup. Expanding the tests
5197 for catch_warnings() also led to an improvement in the raising of a
5198 DeprecationWarning related to warnings.warn_explicit().
5199
Benjamin Peterson973e6c22008-09-01 23:12:58 +00005200- The deprecation warnings for the old camelCase threading API were removed.

5222
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00005223- Issue #2975: When compiling several extension modules with Visual Studio 2008
5224 from the same python interpreter, some environment variables would grow
5225 without limit.
5226
Benjamin Peterson37346b22008-08-23 20:27:43 +00005227- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005264What's New in Python 2.6 beta 3?
5265================================
5266
Barry Warsaw07a4a382008-08-21 01:15:08 +00005267*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00005268
5269Core and Builtins
5270-----------------
5271
Guido van Rossumf8402962008-08-20 15:01:50 +00005272- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
5273 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
5274 extensions do not automatically benefit from the class attribute
5275 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
5276 to their tp_flags field if they care. This is a backwards
5277 compatibility feature; in 3.0, all types will use the cache by
5278 default.
5279
Benjamin Petersonf647dc12008-08-20 01:27:30 +00005280- Keyword arguments can now follow starred arguments. (``f(a, *args,
5281 keyword=23)`` is now valid syntax.)
5282
Thomas Heller0ad5ae02008-08-19 19:25:04 +00005283- ctypes function pointers that are COM methods have a boolean True
5284 value again.
5285
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00005286- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
5287 by denying s# to parse objects that have a releasebuffer procedure,
5288 and introducing s*.
5289
Georg Brandl1e13ea92008-08-11 09:07:59 +00005290- Issue #3537: Fix an assertion failure when an empty but presized dict
5291 object was stored in the freelist.
5292
Mark Dickinsonb6467572008-08-04 21:30:09 +00005293- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
5294 ValueError consistently across platforms.
5295
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00005296- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
5297 (64bit Unix, for example), unichr() would truncate its argument and return
5298 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
5299
Neal Norwitze7d8be82008-07-31 17:17:14 +00005300- Apply security patches from Apple.
5301
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00005302- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
5303 PyErr_ExceptionMatches returns 0 when an exception occurs there.
5304
Antoine Pitrou92f82162008-07-25 22:22:08 +00005305- Issue #1819: function calls with several named parameters are now on
5306 average 35% faster (as measured by pybench).
5307
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00005308- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
5309 the python debugger steps into a class statement: the free variables (local
5310 variables defined in an outer scope) would be deleted from the outer scope.
5311
Gregory P. Smith0470bab2008-07-22 04:46:32 +00005312- Issue #2620: Overflow checking when allocating or reallocating memory
5313 was not always being done properly in some python types and extension
5314 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
5315 all been updated to perform better checks and places in the code that
5316 would previously leak memory on the error path when such an allocation
5317 failed have been fixed.

5320-------
5321
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00005322- Issue #3612: Added some missing basic types in ctypes.wintypes.
5323
Benjamin Petersone977ad42008-08-20 01:42:01 +00005324- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
5325 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
5326
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00005327- Issue #2234: distutils failed for some versions of the cygwin compiler. The
5328 version reported by these tools does not necessarily follow the python
5329 version numbering scheme, so the module is less strict when parsing it.
5330
Nick Coghlanf70385a2008-08-18 12:42:46 +00005331- Issue #2235: Added Py3k warnings for types which will become unhashable
5332 under the stricter __hash__ inheritance rules in 3.0. Several types
5333 which did not meet the rules for hash invariants and were already
5334 unhashable in 3.0 have now been explicitly flagged as unhashable in
5335 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
5336 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
5337
Brett Cannon88f801d2008-08-18 00:46:22 +00005338- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
5339 imported into the module but exposed as part of the module's API.
5340
Brett Cannon7b96f072008-08-18 00:41:11 +00005341- Remove an unneeded import of abc.ABCMeta from 'inspect'.
5342
Brett Cannon46225e72008-08-18 00:36:52 +00005343- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00005345- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
5346
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00005347- Issue #3575: Incremental decoder's decode function now takes bytearray
5348 by using 's*' instead of 't#'.
5349
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00005350- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00005351 fails unicode conversion on 2nd parameter. (windows only)
5352
Georg Brandl222e2082010-08-01 22:27:39 +00005353- Issue #2464: urllib2 now supports a malformation in the URL received
Facundo Batista94f243a2008-08-17 03:38:39 +00005354 in a redirect.
5355
Brett Cannonabe423e2008-08-16 21:47:07 +00005356- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00005357 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00005358
Facundo Batistaeb90b782008-08-16 14:44:07 +00005359- Issue #2776: fixed small issue when handling an URL with double slash
5360 after a 302 response in the case of not going through a proxy.
5361
Antoine Pitroub90a8be2008-08-15 21:03:21 +00005362- Issue #2676: in the email package, content-type parsing was hanging on
5363 pathological input because of quadratic or exponential behaviour of a
5364 regular expression.
5365
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00005366- Issue #3476: binary buffered reading through the new "io" library is now
5367 thread-safe.
5368
Brett Cannonbf3157b2008-08-14 05:00:03 +00005369- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
5370 since mimetools itself is deprecated. Because modules are cached, all
5371 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
5372
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00005373- Issue #3134: shutil referenced undefined WindowsError symbol.
5374
Robert Schuppenies14646332008-08-10 11:01:53 +00005375- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
5376 menu entries were not deleted.
5377
Brett Cannon83e81842008-08-09 23:30:55 +00005378- Copied the implementation of reduce() to _functools.reduce() to have a
5379 version that did not raise a DeprecationWarning under -3.
5380
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00005381- Issue #3205: When iterating over a BZ2File fails allocating memory, raise
5382 a MemoryError rather than silently stop the iteration.
5383
Guido van Rossum59ce9012008-08-09 14:55:34 +00005384- Issue #3487: sre "bytecode" validator. Passing invalid "re-bytecode"
5385 to _sre.compile() will now be rejected. This should not affect anybody
5386 since the re.compile() function never generates invalid re-bytecode.
5387
Skip Montanaroa032bf42008-08-08 22:52:51 +00005388- Issue #3436: Make csv.DictReader's fieldnames attribute a property so that
5389 upon first access it can be automatically initialized from the csv file if
5390 it wasn't initialized during instantiation.
5391
Brett Cannon3aa2a492008-08-06 22:28:09 +00005392- Issue #2338: Create imp.reload() to help with transitioning to Python 3.0 as
5393 the reload() built-in has been removed.
5394
Brett Cannon7e30b672008-08-04 21:52:25 +00005395- Changed code in the following modules/packages to remove warnings raised

5464-----------------
5465
Georg Brandl3e483f62008-07-16 22:57:41 +00005466- Issue #3156: Fix inconsistent behavior of the bytearray type: all
5467 its methods now allow for items objects that can be converted to
5468 an integer using operator.index().
5469
Mark Dickinson64b7e502008-07-16 09:40:03 +00005470- Issue #3360: Fix incorrect parsing of '020000000000.0', which
5471 produced a ValueError instead of giving the correct float.
5472
Eric Smitha5fa5a22008-07-16 00:11:49 +00005473- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
5474 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
5475
Mark Dickinson7103aa42008-07-15 19:08:33 +00005476- Issue #3008: the float type has a new instance method 'float.hex'
5477 and a new class method 'float.fromhex' to convert floating-point
5478 numbers to and from hexadecimal strings, respectively.
5479
Nick Coghlan6d6bd442008-07-15 15:40:22 +00005480- Issue #2235: __hash__ is once again inherited by default. To allow
5481 collections.Hashable to remain meaningful in the presence of the
5482 default hash implementation (object.__hash__), it is now possible
5483 to explicit block inheritance of hash by setting __hash__=None at
5484 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
5485 level.
5486
Nick Coghlanb028f502008-07-13 14:52:36 +00005487- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
5488 the parent module cannot be found while performing an absolute import.
5489 This means that an incorrectly defined __package__ attribute will
5490 now only prevent relative imports in that module rather than causing
5491 all imports from that module to fail.
5492
Nick Coghlan14ff9942008-07-08 14:21:42 +00005493- Issue #2517: Allow unicode messages in Exceptions again by correctly

5503 another thread's dictionary.
5504
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00005505- Issue #3004: Minor change to slice.indices(): the start and stop
5506 arguments are now treated identically, making the behaviour easier
5507 to describe and understand. For example, slice(None, -10,
5508 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
5509 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
5510 10, -1).
5511
Georg Brandl278fc502008-07-19 12:46:12 +00005512- Issue #3219: Calling a function with repeated keyword arguments,
5513 f(a=2, a=23), would not cause a syntax error. This was a regression
5514 from 2.4 caused by the switch to the new compiler.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005552- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
5553 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00005554 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00005555 content-length. The problem had been corrected in the 2.4 branch, but never
5556 merged into trunk.

Nick Coghlanc060b0e2008-07-02 13:09:19 +00005571- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the

5573
Brett Cannon8bb8fa52008-07-02 01:57:08 +00005574- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

Ronald Oussoren5640ce22008-06-05 12:58:24 +00005962- On MacOS X it is now possible to install the framework in 64-bit
5963 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00005964 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00005965
5966 This is controlled by the configure argument ``--with-universal-archs``:
5967
5968 - ``--with-universal-archs=all``: install 4-way universal
5969
5970 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
5971
5972 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
5973
5974 This option should be used in combination with ``--enable-universalsdk=``.
5975
5976 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

5984- The PyBytes functions have been renamed to PyByteArray.
Christian Heimes7a990612008-05-26 13:15:11 +00005985
5986- The PyString functions have been renamed to PyBytes. A batch of
5987 defines were added so that the linker still sees the original
5988 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006026- Issue #1631171: Re-implement the 'warnings' module in C (the
6027 original Python code has been kept as backup). This will allow for
6028 using the 'warning's machinery in such places as the parser where
6029 use of pure Python code is not possible. Both the ``showarning()``
6030 and ``formatwarning()`` gain an optional 'line' argument which is
6031 not called by default for backwards-compatibility reasons. Setting
6032 ``warnings.showwarning()`` to an implementation that lacks support
6033 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00006058- The getpass module has been improved on Unix. It now uses /dev/tty
6059 by default and uses stderr instead of stdout. A GetPassWarning is
6060 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006075- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00006076 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00006096- Issue #2550: The approach used by client/server code for obtaining
6097 ports to listen on in network-oriented tests has been refined in an
6098 effort to facilitate running multiple instances of the entire
6099 regression test suite in parallel without issue.
6100 test_support.bind_port() has been fixed such that it will always
6101 return a unique port -- which wasn't always the case with the
6102 previous implementation, especially if socket options had been set
6103 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
6104 new implementation of bind_port() will actually raise an exception
6105 if it is passed an AF_INET/SOCK_STREAM socket with either the
6106 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
6107 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
6108 the socket it's been passed. This currently only applies to
6109 Windows. This option prevents any other sockets from binding to the
6110 host/port we've bound to, thus removing the possibility of the
6111 'non-deterministic' behaviour, as Microsoft puts it, that occurs
6112 when a second SOCK_STREAM socket binds and accepts to a host/port
6113 that's already been bound by another socket. The optional preferred
6114 port parameter to bind_port() has been removed. Under no
6115 circumstances should tests be hard coding ports!
6116
6117 test_support.find_unused_port() has also been introduced, which will
6118 pass a temporary socket object to bind_port() in order to obtain an
6119 unused port. The temporary socket object is then closed and
6120 deleted, and the port is returned. This method should only be used
6121 for obtaining an unused port in order to pass to an external program
6122 (i.e. the -accept [port] argument to openssl's s_server mode) or as
6123 a parameter to a server-oriented class that doesn't give you direct
6124 access to the underlying socket used.
6125
6126 Finally, test_support.HOST has been introduced, which should be used
6127 for the host argument of any relevant socket calls (i.e. bind and
6128 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00006129
6130 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00006131 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00006132 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
6133 test_asynchat and test_socket_ssl.
6134
Georg Brandl3ee81df2008-05-17 18:14:43 +00006135 It is now possible for multiple instances of the regression test
6136 suite to run in parallel without issue.

Eric Smitha73fbe72008-02-23 03:09:44 +00006415- Added the future_builtins module, which contains hex() and oct().
6416 These are the PEP 3127 version of these functions, designed to be
6417 compatible with the hex() and oct() builtins from Python 3.0. They
6418 differ slightly in their output formats from the existing, unchanged
6419 Python 2.6 builtins. The expected usage of the future_builtins
6420 module is:
6421 from future_builtins import hex, oct
6422
Eric Smith7ef40bf2008-02-20 23:34:22 +00006423- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
6424 exponents for exponents with absolute value < 100. Follows C99
6425 standard. This is a change on Windows, which would use 3 digits.
6426 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
6427 so that any alterations it does to the resulting string will be
6428 available in stringlib/formatter.h (for float.__format__).
6429
Eric Smith5a3c1352008-02-19 13:21:56 +00006430- Implemented PEP 3101, Advanced String Formatting. This adds a new
6431 builtin format(); a format() method for str and unicode; a
6432 __format__() method to object, str, unicode, int, long, float, and
6433 datetime; the class string.Formatter; and the C API
6434 PyObject_Format().
6435
Georg Brandl3ee81df2008-05-17 18:14:43 +00006436- Fixed several potential crashes, all caused by specially crafted
6437 __del__ methods exploiting objects in temporarily inconsistent
6438 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00006439
Vinay Sajipb7edfc42008-04-02 21:10:23 +00006440- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00006441 prevent a possible crash: an Abstract Base Class would try to access
6442 a slot on a registered virtual subclass.

6448 in order to allow pymalloc to free more arenas. Python may give back
6449 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00006450
Georg Brandl3ee81df2008-05-17 18:14:43 +00006451- Issue #2045: Fix an infinite recursion triggered when printing a
6452 subclass of collections.defaultdict, if its default_factory is set
6453 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00006454
Christian Heimesf75dbef2008-02-08 00:11:31 +00006455- Fixed a minor memory leak in dictobject.c. The content of the free
6456 list was not freed on interpreter shutdown.
6457
Georg Brandl21e99f42010-03-07 15:23:59 +00006458- Limit free list of method and built-in function objects to 256

6462 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00006463 to compact the internal free lists of pre-allocted ints and floats.
6464
Georg Brandl3ee81df2008-05-17 18:14:43 +00006465- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
6466 calls. Python expected the return type int but the fork familie
6467 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00006468

Georg Brandl3ee81df2008-05-17 18:14:43 +00006478- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
6479 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00006480
Georg Brandl3ee81df2008-05-17 18:14:43 +00006481- Patch #1473257: generator objects gain a gi_code attribute. This is
6482 the same object as the func_code attribute of the function that
6483 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00006484
Georg Brandl3ee81df2008-05-17 18:14:43 +00006485- Issue #1920: "while 0" statements were completely removed by the
6486 compiler, even in the presence of an "else" clause, which is
6487 supposed to be run when the condition is false. Now the compiler
6488 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00006489
Guido van Rossumeead05f2008-01-24 18:21:02 +00006490- A few crashers fixed: weakref_in_del.py (issue #1377858);
6491 loosing_dict_ref.py (issue #1303614, test67.py);
6492 borrowed_ref_[34].py (not in tracker).
6493
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00006494- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00006495 suppressed while an extension is loaded by calling SetErrorMode in
6496 dynload_win.c. The error is still reported properly.
6497
Georg Brandl3ee81df2008-05-17 18:14:43 +00006498- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00006499 several extension methods and modules do not work without unicode
6500 support.
6501
Georg Brandl26543b12008-01-21 18:36:51 +00006502- Issue #1882: when compiling code from a string, encoding cookies in the
6503 second line of code were not always recognized correctly.
6504
Georg Brandl14404b62008-01-19 19:27:05 +00006505- Issue #1679: "0x" was taken as a valid integer literal.
6506
Georg Brandl6caad7d2008-01-26 14:19:22 +00006507- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00006508 added.
6509
Christian Heimesc94e2b52008-01-14 04:13:37 +00006510- sys.float_info / PyFloat_GetInfo: The floating point information
6511 object was converted from a dict to a specialized structseq object.
6512
Georg Brandl3ee81df2008-05-17 18:14:43 +00006513- Patch #1816: Added sys.flags structseq. It exposes the status of
6514 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00006515
Georg Brandl3ee81df2008-05-17 18:14:43 +00006516- Objects/structseq.c: Implemented new structseq representation. The
6517 patch makes structseqs (e.g. the return value of os.stat) more
6518 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00006519
Georg Brandl3ee81df2008-05-17 18:14:43 +00006520- Patch #1700288: added a type attribute cache that caches method
6521 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00006522
Neal Norwitz3fc15b82008-01-10 05:42:58 +00006523- Bug #1776: __import__() no longer accepts filenames on any platform.
6524 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00006525
Georg Brandlaed6c662008-01-07 17:25:53 +00006526- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
6527
Georg Brandl3ee81df2008-05-17 18:14:43 +00006528- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
6529 envvar and sys.dont_write_bytecode attribute. All these can be set
6530 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00006531
Georg Brandl3ee81df2008-05-17 18:14:43 +00006532- Improve some exception messages when Windows fails to load an
6533 extension module. Now we get for example '%1 is not a valid Win32
6534 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00006535
Georg Brandl3ee81df2008-05-17 18:14:43 +00006536- Bug #1481296: Fixed long(float('nan')) != 0L.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006538- Issue #1640: Added math.isinf(x), math.isnan(x) and math.copysign(x,
6539 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00006540
Christian Heimes0a8143f2007-12-18 23:22:54 +00006541- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00006542 and INF. float("nan"), float("inf") and float("-inf") now work on
6543 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00006544
Georg Brandl3ee81df2008-05-17 18:14:43 +00006545- Compiler now generates simpler and faster code for dictionary
6546 literals. The oparg for BUILD_MAP now indicates an estimated
6547 dictionary size. There is a new opcode, STORE_MAP, for adding
6548 entries to the dictionary.
Raymond Hettingerfd7ed402007-12-18 21:24:09 +00006549
Georg Brandl3ee81df2008-05-17 18:14:43 +00006550- Issue #1638: %zd configure test fails on Linux.
Christian Heimesdb3d6cb2007-12-16 21:39:43 +00006551
Georg Brandl3ee81df2008-05-17 18:14:43 +00006552- Issue #1620: New property decorator syntax was modifying the
6553 decorator in place instead of creating a new decorator object.
Christian Heimes90e10e72007-12-14 02:35:23 +00006554
Georg Brandl3ee81df2008-05-17 18:14:43 +00006555- Issue #1538: Avoid copying string in split/rsplit if the split char
6556 is not found.
Skip Montanaro26015492007-12-08 15:33:24 +00006557
Andrew M. Kuchling395fe442007-12-05 13:27:20 +00006558- Issue #1553: An erroneous __length_hint__ can make list() raise a
Christian Heimes7cc1c6f2007-12-05 12:52:34 +00006559 SystemError.
6560
Nick Coghlanef01d822007-12-03 12:55:17 +00006561- PEP 366: Allow explicit relative imports when executing modules
6562 inside packages with the -m switch via a new module level
6563 __package__ attribute.
6564
Georg Brandl3ee81df2008-05-17 18:14:43 +00006565- Issue #1402: Fix a crash on exit, when another thread is still
6566 running, and if the deallocation of its frames somehow calls the
6567 PyGILState_Ensure() / PyGILState_Release() functions.
Amaury Forgeot d'Arcbe49a902007-11-30 20:37:22 +00006568

Amaury Forgeot d'Arcce7d10c2007-11-24 13:44:17 +00006572 attribute of an empty cell object.
6573
Georg Brandl3ee81df2008-05-17 18:14:43 +00006574- Issue #1460: The utf-7 incremental decoder did not accept truncated
6575 input. It now correctly saves its state between chunks of data.
Amaury Forgeot d'Arcf57375a2007-11-21 01:38:26 +00006576
Georg Brandl3ee81df2008-05-17 18:14:43 +00006577- Patch #1739468: Directories and zipfiles containing a __main__.py
6578 file can now be directly executed by passing their name to the
6579 interpreter. The directory/zipfile is automatically inserted as the
6580 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00006581
Georg Brandl3ee81df2008-05-17 18:14:43 +00006582- Issue #1265: Fix a problem with sys.settrace, if the tracing
6583 function uses a generator expression when at the same time the
6584 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00006585
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00006586- sets and frozensets now have an isdisjoint() method.
6587
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00006588- optimize the performance of builtin.sum().
6589
Neal Norwitz44f326e2007-10-05 05:29:17 +00006590- Fix warnings found by the new version of the Coverity checker.
6591
Georg Brandl21e99f42010-03-07 15:23:59 +00006592- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00006593 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
6594 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00006595
Georg Brandl3ee81df2008-05-17 18:14:43 +00006596- Issue #1686386: Tuple's tp_repr did not take into account the
6597 possibility of having a self-referential tuple, which is possible
6598 from C code. Nor did object's tp_str consider that a type's tp_str
6599 could do something that could lead to an inifinite recursion.
6600 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
6601 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00006602
Georg Brandl3ee81df2008-05-17 18:14:43 +00006603- Issue #1164: It was possible to trigger deadlock when using the
6604 'print' statement to write to a file since the GIL was not released
6605 as needed. Now PyObject_Print() does the right thing along with
6606 various tp_print implementations of the built-in types and those in
6607 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00006608
Georg Brandl3ee81df2008-05-17 18:14:43 +00006609- Issue #1147: Exceptions were directly allowing string exceptions in
6610 their throw() method even though string exceptions no longer
6611 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00006612
Georg Brandl3ee81df2008-05-17 18:14:43 +00006613- Issue #1096: Prevent a segfault from getting the repr of a very
6614 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00006615
Brett Cannon1e534b52007-09-07 04:18:30 +00006616- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00006617 PyObject_Call() never calling back out to Python code to trigger
6618 recursion depth updates/checks. Required the creation of a static
6619 RuntimeError instance in case normalizing an exception put the
6620 recursion check value past its limit. Fixes crashers
6621 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00006622
Georg Brandl3ee81df2008-05-17 18:14:43 +00006623- Patch #1031213: Decode source line in SyntaxErrors back to its
6624 original source encoding.

6627 with %G.
6628
Georg Brandl3ee81df2008-05-17 18:14:43 +00006629- Prevent expandtabs() on string and unicode objects from causing a
6630 segfault when a large width is passed on 32-bit platforms.
Neal Norwitz7dbd2a32007-06-09 03:36:34 +00006631

Georg Brandla5ea6892007-06-01 11:33:33 +00006635
Neal Norwitz0ac60192007-05-27 04:08:54 +00006636- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00006637 __*__ attributes. (Some already existed, e.g., __doc__ and
6638 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00006639
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00006640- Add -3 option to the interpreter to warn about features that are
6641 deprecated and will be changed/removed in Python 3.0.
6642
Georg Brandl2134e752007-05-21 20:34:16 +00006643- Patch #1686487: you can now pass any mapping after '**' in function
6644 calls.
6645
Collin Winter62903052007-05-18 23:11:24 +00006646- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00006647 "except E as target:". This is to provide forwards compatibility
6648 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00006649
Brett Cannon229cee22007-05-05 01:34:02 +00006650- Deprecate BaseException.message as per PEP 352.
6651
Georg Brandl3ee81df2008-05-17 18:14:43 +00006652- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00006653 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00006654
Vinay Sajip8549ce32007-05-06 17:53:37 +00006655- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00006656 setting a plain string, ie don't expand to single letter identifiers.
6657
Raymond Hettinger13936692007-04-11 18:40:58 +00006658- Request #1191699: Slices can now be pickled.
6659
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00006660- Request #1193128: str.translate() now allows a None argument for
6661 translations that only remove characters without re-mapping the
6662 remaining characters.
6663
Georg Brandl5cb76c12007-03-21 09:00:39 +00006664- Patch #1682205: a TypeError while unpacking an iterable is no longer
6665 masked by a generic one with the message "unpack non-sequence".
6666
Neal Norwitzaa754b72007-03-21 06:39:48 +00006667- Remove unused file Python/fmod.c.
6668
Guido van Rossum143b5642007-03-23 04:58:42 +00006669- Bug #1683368: The object.__init__() and object.__new__() methods are
6670 now stricter in rejecting excess arguments. The only time when
6671 either allows excess arguments is when it is not overridden and the
6672 other one is. For backwards compatibility, when both are
6673 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00006674 warning later). Also, type.__init__() insists on the same signature
6675 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00006676
Georg Brandl3ee81df2008-05-17 18:14:43 +00006677- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
6678 object to complex using its __complex__() method before falling back
6679 to the __float__() method. Therefore, the functions in the cmath
6680 module now can operate on objects that define a __complex__()
6681 method.
Georg Brandl2b869942007-03-17 16:08:45 +00006682
Georg Brandl3ee81df2008-05-17 18:14:43 +00006683- Patch #1623563: allow __class__ assignment for classes with
6684 __slots__. The old and the new class are still required to have the
6685 same slot names.
Žiga Seilnacht6f2d09c2007-03-16 11:59:38 +00006686
Georg Brandl3ee81df2008-05-17 18:14:43 +00006687- Patch #1642547: Fix an error/crash when encountering syntax errors
6688 in complex if statements.

Georg Brandl3ee81df2008-05-17 18:14:43 +00006690- Patch #1462488: Python no longer segfaults when
6691 ``object.__reduce_ex__()`` is called with an object that is faking
6692 its type.
Žiga Seilnacht20f43d32007-03-15 11:44:55 +00006693
Georg Brandl3ee81df2008-05-17 18:14:43 +00006694- Patch #1680015: Don't modify __slots__ tuple if it contains an
6695 unicode name.

Georg Brandl5240d742007-03-13 20:46:32 +00006697- Patch #1444529: the builtin compile() now accepts keyword arguments.
6698
Georg Brandl7b9c5552007-03-12 14:30:05 +00006699- Bug #1678647: write a newline after printing an exception in any
6700 case, even when converting the value to a string failed.
6701
Georg Brandl871f1bc2007-03-12 13:17:36 +00006702- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00006703 its argument, if it exists. If not, it will work like before. This
6704 allows customizing the output of dir() in the presence of a
6705 __getattr__().
Georg Brandl871f1bc2007-03-12 13:17:36 +00006706
Collin Winter276887b2007-03-12 16:11:39 +00006707- Patch #922167: Python no longer segfaults when faced with infinitely
6708 self-recursive reload() calls (as reported by bug #742342).
6709
Georg Brandl3ee81df2008-05-17 18:14:43 +00006710- Patch #1675981: remove unreachable code from ``type.__new__()``
6711 method.
Žiga Seilnacht89032082007-03-11 15:54:54 +00006712
Georg Brandl3ee81df2008-05-17 18:14:43 +00006713- Patch #1491866: change the complex() constructor to allow
6714 parthensized forms. This means complex(repr(x)) now works instead of
6715 raising a ValueError.

Georg Brandl4e933132006-09-06 20:05:58 +00006820- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.

7226 ".cpp" too.
7227
Facundo Batistad918a652007-04-24 13:54:38 +00007228- As specified in RFC 2616, an HTTP response like 2xx indicates that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007229 the client's request was successfully received, understood, and
7230 accepted. Now in these cases no error is raised in urllib (issue
7231 #1177) and urllib2.
Facundo Batistad918a652007-04-24 13:54:38 +00007232

Facundo Batistab6a5c9d2007-03-29 18:22:35 +00007239- Added a timeout parameter to the constructor of other protocols
7240 (telnetlib, ftplib, smtplib and poplib). This is second part of the
7241 work started with create_connection() and timeout in httplib, and
7242 closes patch #723312.
7243
Vinay Sajip8549ce32007-05-06 17:53:37 +00007244- Patch #1676823: Added create_connection() to socket.py, which may be
7245 called with a timeout, and use it from httplib (whose HTTPConnection
Facundo Batista70f996b2007-05-21 17:32:32 +00007246 and HTTPSConnection now accept an optional timeout).
Facundo Batista07c78be2007-03-23 18:54:07 +00007247
Martin v. Löwis0af33882007-03-23 13:27:15 +00007248- Bug #978833: Revert r50844, as it broke _socketobject.dup.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007255- Patch #1273829: os.walk() now has a "followlinks" parameter. If set
7256 to True (which is not the default), it visits symlinks pointing to
Georg Brandlcae9f3d2007-03-21 09:10:29 +00007257 directories.
7258

7260 GNOME or KDE browser, depending on whether there is a session of one

7268
Georg Brandlf66b6032007-03-14 08:27:52 +00007269- Bug #767111: fix long-standing bug in urllib which caused an
Georg Brandl3ee81df2008-05-17 18:14:43 +00007270 AttributeError instead of an IOError when the server's response
7271 didn't contain a valid HTTP status line.
Georg Brandlf66b6032007-03-14 08:27:52 +00007272
Georg Brandl3ee81df2008-05-17 18:14:43 +00007273- Patch #957650: "%var%" environment variable references are now
7274 properly expanded in ntpath.expandvars(), also "~user" home
7275 directory references are recognized and handled on Windows.
Georg Brandl03b90d82007-03-13 22:07:36 +00007276
Georg Brandl3ee81df2008-05-17 18:14:43 +00007277- Patch #1429539: pdb now correctly initializes the __main__ module
7278 for the debugged script, which means that imports from __main__ work
Georg Brandlb6ae6aa2007-03-13 21:58:44 +00007279 correctly now.
7280
Georg Brandlbad6f192007-03-13 21:32:56 +00007281- The nonobvious commands.getstatus() function is now deprecated.

7287
Georg Brandl3ee81df2008-05-17 18:14:43 +00007288- Patch #1530482: add pydoc.render_doc() which returns the
7289 documentation for a thing instead of paging it to stdout, which
7290 pydoc.doc() does.
Georg Brandl8441f152007-03-13 20:02:57 +00007291
Georg Brandl3ee81df2008-05-17 18:14:43 +00007292- Patch #1533909: the timeit module now accepts callables in addition

7298 parameter which can be set to False to prevent the default
7299 delete-on-close behavior.
Georg Brandl35ef9c12007-03-13 18:31:49 +00007300
Georg Brandl9e6b4702007-03-13 18:15:41 +00007301- Patch #1581073: add a flag to textwrap that prevents the dropping of
7302 whitespace while wrapping.
7303
Georg Brandl92a6bae2007-03-13 17:43:32 +00007304- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00007305 are set for invalid interpolation sequences that would lead to
7306 errors on reading back those values.
Georg Brandl92a6bae2007-03-13 17:43:32 +00007307

7320
Georg Brandl94fe3f52007-03-13 09:32:11 +00007321- Patch #1635454: the csv.DictWriter class now includes the offending
Georg Brandl3ee81df2008-05-17 18:14:43 +00007322 field names in its exception message if you try to write a record
7323 with a dictionary containing fields not in the CSV field names list.

Collin Winter22c42ba2007-03-10 02:51:26 +00007341

7349 returned string up to the first NUL character.
7350

7360
Georg Brandl3ee81df2008-05-17 18:14:43 +00007361- unittest now verifies more of its assumptions. In particular,
7362 TestCase and TestSuite subclasses (not instances) are no longer
7363 accepted in TestSuite.addTest(). This should cause no
7364 incompatibility since it never made sense with ordinary subclasses
7365 -- the failure just occurred later, with a more cumbersome
7366 exception.
Georg Brandl9caadf82007-03-08 18:37:31 +00007367

7375 given a unicode argument and os.listdir() returns unicode filenames.
7376
Georg Brandl3ee81df2008-05-17 18:14:43 +00007377- Patch #1673619: setup.py identifies extension modules it doesn't

7379 build.

Georg Brandl3ee81df2008-05-17 18:14:43 +00007755 time so that opening a database previously created with the DB_DUP
7756 or DB_DUPSORT flag set will keep the proper behavior on subsequent
7757 opens. Specifically: dictionary assignment to a DB object will
7758 replace all values for a given key when the database allows
7759 duplicate values. DB users should use DB.put(k, v) when they want
7760 to store duplicates; not DB[k] = v.

7767 characters with ASCII value less than 32. Also, it correctly quotes
7768 dots only if they occur on a single line, as opposed to the previous
7769 behavior of quoting dots if they are the second character of any
7770 line.
Georg Brandl4aef7272007-03-13 22:49:43 +00007771
