......@@ -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. Changed to be more standard-conforming.
- Patch #1542451: disallow continue anywhere under a finally.
- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
- The return tuple from str.rpartition(sep) is (tail, sep, head) where
head is the original string if sep was not found.
- Bug #1520864: unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again. Fixing this problem
required changing the .pyc magic number. This means that .pyc files
generated before 2.5c2 will be regenerated.
- ``with`` and ``as`` are now keywords.
- Bug #1664966: Fix crash in exec if Unicode filename can't be decoded.
- Issue #1537: Changed GeneratorExit's base class from Exception to
BaseException.
- Fix Issue #1703448: A joined thread could show up in the
threading.enumerate() list after the join() for a brief period until
it actually exited.

only useful in Unix/Linux environments.
- Bug #1706381: Specifying the SWIG option "-c++" in the setup.py file
(as opposed to the command line) will now write file names ending in
".cpp" too.

called with a timeout, and use it from httplib (whose HTTPConnection
and HTTPSConnection now accept an optional timeout).

AttributeError instead of an IOError when the server's response didn't
contain a valid HTTP status line.
- Patch #957650: "%var%" environment variable references are now properly
expanded in ntpath.expandvars(), also "~user" home directory references
are recognized and handled on Windows.

Python program, optionally with different arguments.
- Patch #1649190: Adding support for _Bool to ctypes as c_bool.
- Patch #1530482: add pydoc.render_doc() which returns the documentation
for a thing instead of paging it to stdout, which pydoc.doc() does.

strings for the code to time and the setup code. Also added two
convenience functions for instantiating a Timer and calling its methods.
- Patch #1537850: tempfile.NamedTemporaryFile now has a "delete" parameter
which can be set to False to prevent the default delete-on-close
behavior.
- Patch #1581073: add a flag to textwrap that prevents the dropping of
whitespace while wrapping.

are set for invalid interpolation sequences that would lead to errors
on reading back those values.
- Added support for the POSIX.1-2001 (pax) format to tarfile.py. Extended
and cleaned up the test suite. Added a new testtar.tar.

and server_activate() in the constructors for TCPServer, SimpleXMLRPCServer
and DocXMLRPCServer.
- Bug #1531963: Make SocketServer.TCPServer's server_address always
be equal to calling getsockname() on the server's socket. Fixed by
patch #1545011.

never made sense with ordinary subclasses -- the failure just occurred
later, with a more cumbersome exception.
- Patch #787789: allow to pass custom TestRunner instances to unittest's
main() function.
- Patches #1550273, #1550272: fix a few bugs in unittest and add a

- Fixes for 64-bit Windows: In ctypes.wintypes, correct the
definitions of HANDLE, WPARAM, LPARAM data types. Make
parameterless foreign function calls work.
- The version number of the ctypes package changed to "1.1.0".
- Bug #1627575: logging: Added _open() method to FileHandler which can
be used to reopen files. The FileHandler instance now saves the
encoding (which can be None) in an attribute called "encoding".
- Bug #411881: logging.handlers: bare except clause removed from
SMTPHandler.emit. Now, only ImportError is trapped.

bytes.
- The implementation of UnicodeError objects has been simplified (start and end
attributes are now stored directly as Py_ssize_t members).
- Issue829951: In the smtplib module, SMTP.starttls() now complies with
RFC 3207 and forgets any knowledge obtained from the server not obtained
from the TLS negotiation itself. Patch contributed by Bill Fenner.
- Issue1339: The smtplib.SMTP class has been refactored a bit such
that the SMTP.starttls() caller no longer needs to call ehlo()
beforehand. SMTP.starttls() now raises an exception of the server
does not claim to support starttls. Adds the SMTP.ehlo_or_helo_if_needed()
method. Patch contributed by Bill Fenner.

time so that opening a database previously created with the DB_DUP or
DB_DUPSORT flag set will keep the proper behavior on subsequent opens.
Specifically: dictionary assignment to a DB object will replace all
values for a given key when the database allows duplicate values.
DB users should use DB.put(k, v) when they want to store duplicates; not
DB[k] = v.
- Add the bsddb.db.DBEnv.lock_id_free method.
- Bug #1686475: Support stat'ing open files on Windows again.

Tests
-----
- Refactor test_logging to use doctest.
- Refactor test_profile and test_cprofile to use the same code to profile.
- Make test_runpy reentrant by fixing _check_module to clear out any module
being tested. Was causing an error by __import__ doing a reload on the
second run and thus suppressing bytecode recreation.

test_urllib2net and raise test.test_support.ResourceDenied.
- Patch #1559413: Fix test_cmd_line if sys.executable contains a space.

to preserve user/group and permissions. Added also a --nobackup option
to not create the backup if the user is concerned regarding this. Check
issue 1050828 for more details.
- Tools/scripts/win_add2path.py was added. The simple script modifes the
PATH environment var of the HKCU tree and adds the python bin and script
directory.
- Tools/18n/pygettext.py was added to the list of scripts installed by
Tools/scripts/setup.py (tracker item 642309).

newer GCC versions may optimize away overflow buffer overflow checks
without this option!
- Patch #1418: Make the AC_REPLACE_FUNCS object files actually work.
- Add a FAST_LOOPS build option that speeds-up looping by trading away
periodic threadstate and signal checking in tight loops. By default,

-----
- Unified naming convention for free lists and their limits. All free lists
in Object/ are named ``free_list``, the counter ``numfree`` and the upper
limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.
- ``PySet_Add()`` can now modify a newly created frozenset. Similarly to
``PyTuple_SetItem``, it can be used to populate a brand new frozenset; but
it does not steal a reference to the added item.
- Added ``PySet_Check()`` and ``PyFrozenSet_Check()`` to the set API.
- Backport of PyUnicode_FromString(), _FromStringAndSize(), _Format and
_FormatV from Python 3.0. Made PyLong_AsSsize_t and PyLong_FromSsize_t

- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
``PyFloat_GetInfo()`` to the float API.
- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
format code incorrectly truncated the length to an int, even when
PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
results with huge strings.
- Issue #1629: Renamed Py_Size, Py_Type and Py_Refcnt to Py_SIZE, Py_TYPE
and Py_REFCNT.
- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.
- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
- Patch #1733960: Allow T_LONGLONG to accept ints.
- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
- Added a new API function ``PyImport_ImportModuleNoBlock``.
- Bug #1637022: Prefix AST symbols with _Py_.
- Fix some leftovers from the conversion from int to Py_ssize_t
(relevant to strings and sequences of more than 2**31 items).
- Make _PyGILState_NoteThreadState() static, it was not used anywhere
outside of pystate.c and should not be necessary.
- ``PyImport_Import`` and ``PyImport_ImportModule`` now always do absolute
imports. In earlier versions they might have used relative imports under
some conditions.
- Added case insensitive comparison methods ``PyOS_stricmp(char*, char*)``
and ``PyOS_strnicmp(char*, char*, Py_ssize_t)``.
- Bug #1542693: remove semi-colon at end of PyImport_ImportModuleEx macro
so it can be used as an expression.
Windows
-------
- Patch #1706: Drop support for Win9x, WinME and NT4. Python now requires
Windows 2000 or greater. 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().
