@@ -89,1561 +89,28 @@ Core and Builtins - Issue #1564: The set implementation should special-case PyUnicode instead of PyString. -- Issue #1402: Fix a crash on exit, when another thread is still running, and - if the deallocation of its frames somehow calls the PyGILState_Ensure() / - PyGILState_Release() functions. - -- Expose the Py_Py3kWarningFlag as sys.py3kwarning. - -- Issue #1445: Fix a SystemError when accessing the ``cell_contents`` - attribute of an empty cell object. - -- Issue #1460: The utf-7 incremental decoder did not accept truncated input. - It now correctly saves its state between chunks of data. - -- Patch #1739468: Directories and zipfiles containing a __main__.py file can - now be directly executed by passing their name to the interpreter. The - directory/zipfile is automatically inserted as the first entry in sys.path. - -- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a - generator expression when at the same time the executed code is closing a - paused generator. - -- sets and frozensets now have an isdisjoint() method. - -- optimize the performance of builtin.sum(). - -- Fix warnings found by the new version of the Coverity checker. - -- The enumerate() builtin function is no longer bounded to sequences smaller - than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically - shifts from ints to longs. - -- Issue #1686386: Tuple's tp_repr did not take into account the possibility of - having a self-referential tuple, which is possible from C code. Nor did - object's tp_str consider that a type's tp_str could do something that could - lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(), - respectively, fixed the issues. - -- Issue #1164: It was possible to trigger deadlock when using the 'print' - statement to write to a file since the GIL was not released as needed. Now - PyObject_Print() does the right thing along with various tp_print - implementations of the built-in types and those in the collections module. - -- Issue #1147: Exceptions were directly allowing string exceptions in their - throw() method even though string exceptions no longer allowed. - -- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested - list by using the recursion counter. - -- Issue #1202533: Fix infinite recursion calls triggered by calls to - PyObject_Call() never calling back out to Python code to trigger recursion - depth updates/checks. Required the creation of a static RuntimeError - instance in case normalizing an exception put the recursion check value past - its limit. Fixes crashers infinite_rec_(1|2|4|5).py. - - Patch #1031213: Decode source line in SyntaxErrors back to its original source encoding. -- Patch #1673759: add a missing overflow check when formatting floats - with %G. - -- Prevent expandtabs() on string and unicode objects from causing a segfault - when a large width is passed on 32-bit platforms. - -- Bug #1733488: Fix compilation of bufferobject.c on AIX. - -- Bug #1722485: remove docstrings again when running with -OO. - -- Add new attribute names for function objects. All the func_* become - __*__ attributes. (Some already existed, e.g., __doc__ and __name__.) - -- Add -3 option to the interpreter to warn about features that are - deprecated and will be changed/removed in Python 3.0. - -- Patch #1686487: you can now pass any mapping after '**' in function - calls. - -- except clauses may now be spelled either "except E, target:" or - "except E as target:". This is to provide forwards compatibility with - Python 3.0. - -- Deprecate BaseException.message as per PEP 352. - -- Bug #1303614: don't expose object's __dict__ when the dict is - inherited from a builtin base. - -- When __slots__ are set to a unicode string, make it work the same as - setting a plain string, ie don't expand to single letter identifiers. - -- Request #1191699: Slices can now be pickled. - -- Request #1193128: str.translate() now allows a None argument for - translations that only remove characters without re-mapping the - remaining characters. - -- Patch #1682205: a TypeError while unpacking an iterable is no longer - masked by a generic one with the message "unpack non-sequence". - -- Remove unused file Python/fmod.c. - -- Bug #1683368: The object.__init__() and object.__new__() methods are - now stricter in rejecting excess arguments. The only time when - either allows excess arguments is when it is not overridden and the - other one is. For backwards compatibility, when both are - overridden, it is a deprecation warning (for now; maybe a Py3k - warning later). Also, type.__init__() insists on the same signature - as supported by type.__new__(). - -- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object - to complex using its __complex__() method before falling back to the - __float__() method. Therefore, the functions in the cmath module now - can operate on objects that define a __complex__() method. - -- Patch #1623563: allow __class__ assignment for classes with __slots__. - The old and the new class are still required to have the same slot names. - -- Patch #1642547: Fix an error/crash when encountering syntax errors in - complex if statements. - -- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()`` - is called with an object that is faking its type. - -- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode - name. - -- Patch #1444529: the builtin compile() now accepts keyword arguments. - -- Bug #1678647: write a newline after printing an exception in any - case, even when converting the value to a string failed. - -- The dir() function has been extended to call the __dir__() method on - its argument, if it exists. If not, it will work like before. This allows - customizing the output of dir() in the presence of a __getattr__(). - -- Patch #922167: Python no longer segfaults when faced with infinitely - self-recursive reload() calls (as reported by bug #742342). - -- Patch #1675981: remove unreachable code from ``type.__new__()`` method. - -- Patch #1491866: change the complex() constructor to allow parthensized - forms. This means complex(repr(x)) now works instead of raising a - ValueError. - -- Patch #703779: unset __file__ in __main__ after running a file. This - makes the filenames the warning module prints much more sensible when - a PYTHONSTARTUP file is used. - -- Variant of patch #697613: don't exit the interpreter on a SystemExit - exception if the -i command line option or PYTHONINSPECT environment - variable is given, but break into the interactive interpreter just like - on other exceptions or normal program exit. - -- Patch #1638879: don't accept strings with embedded NUL bytes in long(). - -- Bug #1674503: close the file opened by execfile() in an error condition. - -- Patch #1674228: when assigning a slice (old-style), check for the - sq_ass_slice instead of the sq_slice slot. - -- When printing an unraisable error, don't print exceptions. before the name. - This duplicates the behavior whening normally printing exceptions. - -- Bug #1653736: Properly discard third argument to slot_nb_inplace_power. - -- PEP 352: Raising a string exception now triggers a TypeError. Attempting to - catch a string exception raises DeprecationWarning. - -- Bug #1377858: Fix the segfaulting of the interpreter when an object created - a weakref on itself during a __del__ call for new-style classes (classic - classes still have the bug). - -- Bug #1579370: Make PyTraceBack_Here use the current thread, not the - frame's thread state. - -- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py - -- Prevent seg fault on shutdown which could occur if an object - raised a warning. - -- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main, - to avoid relying on atexit. - -- Bug #1590891: random.randrange don't return correct value for big number - -- Patch #1586791: Better exception messages for some operations on strings, - tuples and lists. - -- Bug #1067760: Deprecate passing floats to file.seek. - -- Bug #1591996: Correctly forward exception in instance_contains(). - -- Bug #1588287: fix invalid assertion for `1,2` in debug builds. - -- Bug #1576657: when setting a KeyError for a tuple key, make sure that - the tuple isn't used as the "exception arguments tuple". - -- Bug #1565514, SystemError not raised on too many nested blocks. - -- Bug #1576174: WindowsError now displays the windows error code - again, no longer the posix error code. - -- Patch #1549049: Support long values in structmember, issue warnings - if the assigned value for structmember fields gets truncated. - -- Update the peephole optimizer to remove more dead code (jumps after returns) - and inline unconditional jumps to returns. - -- Bug #1545497: when given an explicit base, int() did ignore NULs - embedded in the string to convert. - -- Bug #1569998: break inside a try statement (outside a loop) is now - recognized and rejected. - -- list.pop(x) accepts any object x following the __index__ protocol. - -- A number of places, including integer negation and absolute value, - were fixed to not rely on undefined behaviour of the C compiler - anymore. - -- Bug #1566800: make sure that EnvironmentError can be called with any - number of arguments, as was the case in Python 2.4. - -- Patch #1567691: super() and new.instancemethod() now don't accept - keyword arguments any more (previously they accepted them, but didn't - use them). - -- Fix a bug in the parser's future statement handling that led to "with" - not being recognized as a keyword after, e.g., this statement: - from __future__ import division, with_statement - -- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)). - -- Fix %zd string formatting on Mac OS X so it prints negative numbers. - -- Allow exception instances to be directly sliced again. - -- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This - allows calling unicode() on exceptions classes directly to succeed. - -- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack. - Also make sure that every exception class has __module__ set to - 'exceptions'. - -- Bug #1550983: emit better error messages for erroneous relative - imports (if not in package and if beyond toplevel package). - -- Overflow checking code in integer division ran afoul of new gcc - optimizations.

The _WINVER and NTDDI_VERSION macros are set to - Win2k for x86/32bit builds and WinXP for AMD64 builds. - -- Conditionalize definition of _CRT_SECURE_NO_DEPRECATE - and _CRT_NONSTDC_NO_DEPRECATE. - -- Bug #1216: Restore support for Visual Studio 2002. - - -Mac ---- - -- cfmfile now raises a DeprecationWarning. - -- buildtools now raises a DeprecationWarning. - -- Removed the macfs module. It had been deprecated since Python 2.5. This - lead to the deprecation of macostools.touched() as it relied solely on macfs - and was a no-op under OS X. - - -What's New in Python 2.5 release candidate 1? -============================================= - -*Release date: 17-AUG-2006* - -Core and builtins ------------------ - -- Unicode objects will no longer raise an exception when being - compared equal or unequal to a string and a UnicodeDecodeError - exception occurs, e.g. as result of a decoding failure. - - Instead, the equal (==) and unequal (!=) comparison operators will - now issue a UnicodeWarning and interpret the two objects as - unequal. The UnicodeWarning can be filtered as desired using - the warning framework, e.g. silenced completely, turned into an - exception, logged, etc. - - Note that compare operators other than equal and unequal will still - raise UnicodeDecodeError exceptions as they've always done. - -- Fix segfault when doing string formatting on subclasses of long. - -- Fix bug related to __len__ functions using values > 2**32 on 64-bit machines - with new-style classes. - -- Fix bug related to __len__ functions returning negative values with - classic classes. - -- Patch #1538606, Fix __index__() clipping. There were some problems - discovered with the API and how integers that didn't fit into Py_ssize_t - were handled. This patch attempts to provide enough alternatives - to effectively use __index__. - -- Bug #1536021: __hash__ may now return long int; the final hash - value is obtained by invoking hash on the long int. - -- Bug #1536786: buffer comparison could emit a RuntimeWarning. - -- Bug #1535165: fixed a segfault in input() and raw_input() when - sys.stdin is closed. - -- On Windows, the PyErr_Warn function is now exported from - the Python dll again. - -- Bug #1191458: tracing over for loops now produces a line event - on each iteration. Fixing this problem required changing the .pyc - magic number. This means that .pyc files generated before 2.5c1 - will be regenerated. - -- Bug #1333982: string/number constants were inappropriately stored - in the byte code and co_consts even if they were not used, ie - immediately popped off the stack. - -- Fixed a reference-counting problem in property(). - Library ------- |
