======================================================================
+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
+-------
+
+- Fix a bug in the ``compiler`` package that caused invalid code to be
+ generated for generator expressions.
+
+- The distutils version has been changed to 2.5.0. The change to
+ keep it programmatically in sync with the Python version running
+ the code (introduced in 2.5b3) has been reverted. It will continue
+ to be maintained manually as static string literal.
+
+- If the Python part of a ctypes callback function returns None,
+ and this cannot be converted to the required C type, an exception is
+ printed with PyErr_WriteUnraisable. Before this change, the C
+ callback returned arbitrary values to the calling code.
+
+- The __repr__ method of a NULL ctypes.py_object() no longer raises
+ an exception.
+
+- uuid.UUID now has a bytes_le attribute. This returns the UUID in
+ little-endian byte order for Windows. In addition, uuid.py gained some
+ workarounds for clocks with low resolution, to stop the code yielding
+ duplicate UUIDs.
+
+- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
+ before raising SystemExit, allowing IDLE to honor quit() and exit().
+
+- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
+
+- Patch #1536071: trace.py should now find the full module name of a
+ file correctly even on Windows.
+
+- logging's atexit hook now runs even if the rest of the module has
+ already been cleaned up.
+
+- Bug #1112549, fix DoS attack on cgi.FieldStorage.
+
+- Bug #1531405, format_exception no longer raises an exception if
+ str(exception) raised an exception.
+
+- Fix a bug in the ``compiler`` package that caused invalid code to be
+ generated for nested functions.
+
+
+Extension Modules
+-----------------
+
+- Patch #1511317: don't crash on invalid hostname (alias) info.
+
+- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
+ raises the correct exceptions.
+
+- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
+ '-no-stack-protector' compiler flag for OpenBSD has been removed.
+
+- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
+ uses the _as_parameter_ attribute when objects are passed to foreign
+ function calls. The ctypes version number was changed to 1.0.1.
+
+- Bug #1530559, struct.pack raises TypeError where it used to convert.
+ Passing float arguments to struct.pack when integers are expected
+ now triggers a DeprecationWarning.
+
+
+Tests
+-----
+
+- test_socketserver should now work on cygwin and not fail sporadically
+ on other platforms.
+
+- test_mailbox should now work on cygwin versions 2006-08-10 and later.
+
+- Bug #1535182: really test the xreadlines() method of bz2 objects.
+
+- test_threading now skips testing alternate thread stack sizes on
+ platforms that don't support changing thread stack size.
+
+
+Documentation
+-------------
+
+- Patch #1534922: unittest docs were corrected and enhanced.
+
+
+Build
+-----
+
+- Bug #1535502, build _hashlib on Windows, and use masm assembler
+ code in OpenSSL.
+
+- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
+
+- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
+
+
+C API
+-----
+
+- New API for Unicode rich comparisons: PyUnicode_RichCompare()
+
+- Bug #1069160. Internal correctness changes were made to
+ ``PyThreadState_SetAsyncExc()``. A test case was added, and
+ the documentation was changed to state that the return value
+ is always 1 (normal) or 0 (if the specified thread wasn't found).
+
+
+What's New in Python 2.5 beta 3?
+================================
+
+*Release date: 03-AUG-2006*
+
+Core and builtins
+-----------------
+
+- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
+ returned a long (see PEP 353).
+
+- Bug #1515471: string.replace() accepts character buffers again.
+
+- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
+ This provides the proper warning for struct.pack().
+ PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
+
+- Patch #1531113: Fix augmented assignment with yield expressions.
+ Also fix a SystemError when trying to assign to yield expressions.
+
+- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
+ with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
+ used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
+ excessive filesystem operations during imports.
+
+- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
+ operations on signed longs that are formally undefined by C.
+ Unfortunately, at least one compiler now cares about that, so complicated
+ the code to make that compiler happy again.
+
+- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
+
+- Patch #1232023: Stop including current directory in search
+ path on Windows.
+
+- Fix some potential crashes found with failmalloc.
+
+- Fix warnings reported by Klocwork's static analysis tool.
+
+- Bug #1512814, Fix incorrect lineno's when code within a function
+ had more than 255 blank lines.
+
+- Patch #1521179: Python now accepts the standard options ``--help`` and
+ ``--version`` as well as ``/?`` on Windows.
+
+- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
+ again. Fixing this problem required changing the .pyc magic number.
+ This means that .pyc files generated before 2.5b3 will be regenerated.
+
+- Bug #1524317: Compiling Python ``--without-threads`` failed.
+ The Python core compiles again, and, in a build without threads, the
+ new ``sys._current_frames()`` returns a dictionary with one entry,
+ mapping the faux "thread id" 0 to the current frame.
+
+- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
+
+
+Library
+-------
+
+- Fix #1693149. Now you can pass several modules separated by
+ comma to trace.py in the same --ignore-module option.
+
+- Correction of patch #1455898: In the mbcs decoder, set final=False
+ for stream decoder, but final=True for the decode function.
+
+- os.urandom no longer masks unrelated exceptions like SystemExit or
+ KeyboardInterrupt.
+
+- Bug #1525866: Don't copy directory stat times in
+ shutil.copytree on Windows
+
+- Bug #1002398: The documentation for os.path.sameopenfile now correctly
+ refers to file descriptors, not file objects.
+
+- The renaming of the xml package to xmlcore, and the import hackery done
+ to make it appear at both names, has been removed. Bug #1511497,
+ #1513611, and probably others.
+
+- Bug #1441397: The compiler module now recognizes module and function
+ docstrings correctly as it did in Python 2.4.
+
+- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
+ lost that tests are sorted by name before being run. This rarely
+ matters for well-written tests, but can create baffling symptoms if
+ side effects from one test to the next affect outcomes. ``DocTestFinder``
+ has been changed to sort the list of tests it returns.
+
+- The distutils version has been changed to 2.5.0, and is now kept
+ in sync with sys.version_info[:3].
+
+- Bug #978833: Really close underlying socket in _socketobject.close.
+
+- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
+ title().
+
+- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
+ to recursive calls and call it with the failing package name.
+
+- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
+
+- Patch #1515343: Fix printing of deprecated string exceptions with a
+ value in the traceback module.
+
+- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
+
+- Patch #1524429: Use repr() instead of backticks in Tkinter again.
+
+- Bug #1520914: Change time.strftime() to accept a zero for any position in its
+ argument tuple. For arguments where zero is illegal, the value is forced to
+ the minimum value that is correct. This is to support an undocumented but
+ common way people used to fill in inconsequential information in the time
+ tuple pre-2.4.
+
+- Patch #1220874: Update the binhex module for Mach-O.
+
+- The email package has improved RFC 2231 support, specifically for
+ recognizing the difference between encoded (name*0*=<blah>) and non-encoded
+ (name*0=<blah>) parameter continuations. This may change the types of
+ values returned from email.message.Message.get_param() and friends.
+ Specifically in some cases where non-encoded continuations were used,
+ get_param() used to return a 3-tuple of (None, None, string) whereas now it
+ will just return the string (since non-encoded continuations don't have
+ charset and language parts).
+
+ Also, whereas % values were decoded in all parameter continuations, they are
+ now only decoded in encoded parameter parts.
+
+- Bug #1517990: IDLE keybindings on MacOS X now work correctly
+
+- Bug #1517996: IDLE now longer shows the default Tk menu when a
+ path browser, class browser or debugger is the frontmost window on MacOS X
+
+- Patch #1520294: Support for getset and member descriptors in types.py,
+ inspect.py, and pydoc.py. Specifically, this allows for querying the type
+ of an object against these built-in types and more importantly, for getting
+ their docstrings printed in the interactive interpreter's help() function.
+
+
+Extension Modules
+-----------------
+
+- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
+ a socket operation on a socket with a timeout, the exception will be
+ caught correctly. Previously, the exception was not caught.
+
+- Patch #1529514: The _ctypes extension is now compiled on more
+ openbsd target platforms.
+
+- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
+ a memory leak, affecting pickles and deep copies.
+
+- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
+ Paul Eggert.
+
+- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
+
+- Patch #1521817: Index range checking on ctypes arrays containing
+ exactly one element enabled again. This allows iterating over these
+ arrays, without the need to check the array size before.
+
+- Bug #1521375: When the code in ctypes.util.find_library was
+ run with root privileges, it could overwrite or delete
+ /dev/null in certain cases; this is now fixed.
+
+- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
+ default mode for loading shared libraries in ctypes.
+
+- Because of a misspelled preprocessor symbol, ctypes was always
+ compiled without thread support; this is now fixed.
+
+- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
+ methods now allow their database parameter to be None as the
+ sleepycat API allows.
+
+- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
+ bluetooth API compared with Linux and FreeBSD.
+
+Tests
+-----
+
+- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
+ how long the test file should take to play. Now accepts taking 2.93 secs
+ (exact time) +/- 10% instead of the hard-coded 3.1 sec.
+
+- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
+ ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
+ run via ``regrtest.py``. Now they do.
+
+Build
+-----
+
+- Bug #1439538: Drop usage of test -e in configure as it is not portable.
+
+Mac
+---
+
+- PythonLauncher now works correctly when the path to the script contains
+ characters that are treated specially by the shell (such as quotes).
+
+- Bug #1527397: PythonLauncher now launches scripts with the working directory
+ set to the directory that contains the script instead of the user home
+ directory. That latter was an implementation accident and not what users
+ expect.
+
+
+What's New in Python 2.5 beta 2?
+================================
+
+*Release date: 11-JUL-2006*
+
+Core and builtins
+-----------------
+
+- Bug #1441486: The literal representation of -(sys.maxint - 1)
+ again evaluates to a int object, not a long.
+
+- Bug #1501934: The scope of global variables that are locally assigned
+ using augmented assignment is now correctly determined.
+
+- Bug #927248: Recursive method-wrapper objects can now safely
+ be released.
+
+- Bug #1417699: Reject locale-specific decimal point in float()
+ and atof().
+
+- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
+ omit a default "error" argument for NULL pointer. This allows
+ the parser to take a codec from cjkcodecs again.
+
+- Bug #1519018: 'as' is now validated properly in import statements.
+
+- On 64 bit systems, int literals that use less than 64 bits are
+ now ints rather than longs.
+
+- Bug #1512814, Fix incorrect lineno's when code at module scope
+ started after line 256.
+
+- New function ``sys._current_frames()`` returns a dict mapping thread
+ id to topmost thread stack frame. This is for expert use, and is
+ especially useful for debugging application deadlocks. The functionality
+ was previously available in Fazal Majid's ``threadframe`` extension
+ module, but it wasn't possible to do this in a wholly threadsafe way from
+ an extension.
+
+Library
+-------
+
+- Bug #1257728: Mention Cygwin in distutils error message about a missing
+ VS 2003.
+
+- Patch #1519566: Update turtle demo, make begin_fill idempotent.
+
+- Bug #1508010: msvccompiler now requires the DISTUTILS_USE_SDK
+ environment variable to be set in order to the SDK environment
+ for finding the compiler, include files, etc.
+
+- Bug #1515998: Properly generate logical ids for files in bdist_msi.
+
+- warnings.py now ignores ImportWarning by default
+
+- string.Template() now correctly handles tuple-values. Previously,
+ multi-value tuples would raise an exception and single-value tuples would
+ be treated as the value they contain, instead.
+
+- Bug #822974: Honor timeout in telnetlib.{expect,read_until}
+ even if some data are received.
+
+- Bug #1267547: Put proper recursive setup.py call into the
+ spec file generated by bdist_rpm.
+
+- Bug #1514693: Update turtle's heading when switching between
+ degrees and radians.
+
+- Reimplement turtle.circle using a polyline, to allow correct
+ filling of arcs.
+
+- Bug #1514703: Only setup canvas window in turtle when the canvas
+ is created.
+
+- Bug #1513223: .close() of a _socketobj now releases the underlying
+ socket again, which then gets closed as it becomes unreferenced.
+
+- Bug #1504333: Make sgmllib support angle brackets in quoted
+ attribute values.
+
+- Bug #853506: Fix IPv6 address parsing in unquoted attributes in
+ sgmllib ('[' and ']' were not accepted).
+
+- Fix a bug in the turtle module's end_fill function.
+
+- Bug #1510580: The 'warnings' module improperly required that a Warning
+ category be either a types.ClassType and a subclass of Warning. The proper
+ check is just that it is a subclass with Warning as the documentation states.
+
+- The compiler module now correctly compiles the new try-except-finally
+ statement (bug #1509132).
+
+- The wsgiref package is now installed properly on Unix.
+
+- A bug was fixed in logging.config.fileConfig() which caused a crash on
+ shutdown when fileConfig() was called multiple times.
+
+- The sqlite3 module did cut off data from the SQLite database at the first
+ null character before sending it to a custom converter. This has been fixed
+ now.
+
+Extension Modules
+-----------------
+
+- #1494314: Fix a regression with high-numbered sockets in 2.4.3. This
+ means that select() on sockets > FD_SETSIZE (typically 1024) work again.
+ The patch makes sockets use poll() internally where available.
+
+- Assigning None to pointer type fields in ctypes structures possible
+ overwrote the wrong fields, this is fixed now.
+
+- Fixed a segfault in _ctypes when ctypes.wintypes were imported
+ on non-Windows platforms.
+
+- Bug #1518190: The ctypes.c_void_p constructor now accepts any
+ integer or long, without range checking.
+
+- Patch #1517790: It is now possible to use custom objects in the ctypes
+ foreign function argtypes sequence as long as they provide a from_param
+ method, no longer is it required that the object is a ctypes type.
+
+- The '_ctypes' extension module now works when Python is configured
+ with the --without-threads option.
+
+- Bug #1513646: os.access on Windows now correctly determines write
+ access, again.
+
+- Bug #1512695: cPickle.loads could crash if it was interrupted with
+ a KeyboardInterrupt.
+
+- Bug #1296433: parsing XML with a non-default encoding and
+ a CharacterDataHandler could crash the interpreter in pyexpat.
+
+- Patch #1516912: improve Modules support for OpenVMS.
+
+Build
+-----
+
+- Automate Windows build process for the Win64 SSL module.
+
+- 'configure' now detects the zlib library the same way as distutils.
+ Previously, the slight difference could cause compilation errors of the
+ 'zlib' module on systems with more than one version of zlib.
+
+- The MSI compileall step was fixed to also support a TARGETDIR
+ with spaces in it.
+
+- Bug #1517388: sqlite3.dll is now installed on Windows independent
+ of Tcl/Tk.
+
+- Bug #1513032: 'make install' failed on FreeBSD 5.3 due to lib-old
+ trying to be installed even though it's empty.
+
+Tests
+-----
+
+- Call os.waitpid() at the end of tests that spawn child processes in order
+ to minimize resources (zombies).
+
+Documentation
+-------------
+
+- Cover ImportWarning, PendingDeprecationWarning and simplefilter() in the
+ documentation for the warnings module.
+
+- Patch #1509163: MS Toolkit Compiler no longer available.
+
+- Patch #1504046: Add documentation for xml.etree.
+
+
+What's New in Python 2.5 beta 1?
+================================
+
+*Release date: 20-JUN-2006*
+
+Core and builtins
+-----------------
+
+- Patch #1507676: Error messages returned by invalid abstract object operations
+ (such as iterating over an integer) have been improved and now include the
+ type of the offending object to help with debugging.
+
+- Bug #992017: A classic class that defined a __coerce__() method that returned
+ its arguments swapped would infinitely recurse and segfault the interpreter.
+
+- Fix the socket tests so they can be run concurrently.
+
+- Removed 5 integers from C frame objects (PyFrameObject).
+ f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
+
+- Bug #532646: object.__call__() will continue looking for the __call__
+ attribute on objects until one without one is found. This leads to recursion
+ when you take a class and set its __call__ attribute to an instance of the
+ class. Originally fixed for classic classes, but this fix is for new-style.
+ Removes the infinite_rec_3 crasher.
+
+- The string and unicode methods startswith() and endswith() now accept
+ a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
+
+- Buffer objects, at the C level, never used the char buffer
+ implementation even when the char buffer for the wrapped object was
+ explicitly requested (originally returned the read or write buffer).
+ Now a TypeError is raised if the char buffer is not present but is
+ requested.
+
+- Patch #1346214: Statements like "if 0: suite" are now again optimized
+ away like they were in Python 2.4.
+
+- Builtin exceptions are now full-blown new-style classes instead of
+ instances pretending to be classes, which speeds up exception handling
+ by about 80% in comparison to 2.5a2.
+
+- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
+ Unicode 4.1.
+
+- Patch #921466: sys.path_importer_cache is now used to cache valid and
+ invalid file paths for the built-in import machinery which leads to
+ fewer open calls on startup.
+
+- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
+ of-2 bases. The largest speedup is for inputs with about 1000 decimal
+ digits. Conversion from non-power-of-2 bases remains quadratic-time in
+ the number of input digits (it was and remains linear-time for bases
+ 2, 4, 8, 16 and 32).
+
+- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
+ when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
+ an integer close to ``sys.maxint``. This was repaired by patch
+ #1335972, which also gives a nice speedup.
+
+- Patch #1337051: reduced size of frame objects.
+
+- PyErr_NewException now accepts a tuple of base classes as its
+ "base" parameter.
+
+- Patch #876206: function call speedup by retaining allocated frame
+ objects.
+
+- Bug #1462152: file() now checks more thoroughly for invalid mode
+ strings and removes a possible "U" before passing the mode to the
+ C library function.
+
+- Patch #1488312, Fix memory alignment problem on SPARC in unicode
+
+- Bug #1487966: Fix SystemError with conditional expression in assignment
+
+- WindowsError now has two error code attributes: errno, which carries
+ the error values from errno.h, and winerror, which carries the error
+ values from winerror.h. Previous versions put the winerror.h values
+ (from GetLastError()) into the errno attribute.
+
+- Patch #1475845: Raise IndentationError for unexpected indent.
+
+- Patch #1479181: split open() and file() from being aliases for each other.
+
+- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
+ methods were always silently ignored by dictionaries when comparing keys.
+ They are now passed through (except when using the C API function
+ ``PyDict_GetItem()``, whose semantics did not change).
+
+- Bug #1456209: In some obscure cases it was possible for a class with a
+ custom ``__eq__()`` method to confuse dict internals when class instances
+ were used as a dict's keys and the ``__eq__()`` method mutated the dict.
+ No, you don't have any code that did this ;-)
+
+Extension Modules
+-----------------
+
+- Bug #1295808: expat symbols should be namespaced in pyexpat
+
+- Patch #1462338: Upgrade pyexpat to expat 2.0.0
+
+- Change binascii.hexlify to accept a read-only buffer instead of only a char
+ buffer and actually follow its documentation.
+
+- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
+
+- Patch #1478788 (modified version): The functional extension module has
+ been renamed to _functools and a functools Python wrapper module added.
+ This provides a home for additional function related utilities that are
+ not specifically about functional programming. See PEP 309.
+
+- Patch #1493701: performance enhancements for struct module.
+
+- Patch #1490224: time.altzone is now set correctly on Cygwin.
+
+- Patch #1435422: zlib's compress and decompress objects now have a
+ copy() method.
+
+- Patch #1454481: thread stack size is now tunable at runtime for thread
+ enabled builds on Windows and systems with Posix threads support.
+
+- On Win32, os.listdir now supports arbitrarily-long Unicode path names
+ (up to the system limit of 32K characters).
+
+- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
+ As a result, these functions now raise WindowsError instead of OSError.
+
+- ``time.clock()`` on Win64 should use the high-performance Windows
+ ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
+ Windows platforms).
+
+- Calling Tk_Init twice is refused if the first call failed as that
+ may deadlock.
+
+- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
+ accept it without potentially using an uninitialized pointer.
+
+- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
+ assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
+ patch numbers 1494885 and 1494902]
+
+- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
+ [pybsddb project SF patch number 1466734]
+
+- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
+ parameter is supplied. [SF pybsddb bug #1477863]
+
+- bsddb: the __len__ method of a DB object has been fixed to return correct
+ results. It could previously incorrectly return 0 in some cases.
+ Fixes SF bug 1493322 (pybsddb bug 1184012).
+
+- bsddb: the bsddb.dbtables Modify method now raises the proper error and
+ aborts the db transaction safely when a modifier callback fails.
+ Fixes SF python patch/bug #1408584.
+
+- bsddb: multithreaded DB access using the simple bsddb module interface
+ now works reliably. It has been updated to use automatic BerkeleyDB
+ deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
+ database calls that would previously deadlock. [SF python bug #775414]
+
+- Patch #1446489: add support for the ZIP64 extensions to zipfile.
+
+- Patch #1506645: add Python wrappers for the curses functions
+ is_term_resized, resize_term and resizeterm.
+
+Library
+-------
+
+- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
+ functions.

+
+- Patch #1494750: Destroy master after deleting children in
+ Tkinter.BaseWidget.

+- Patch #1455898: The MBCS codec now supports the incremental mode for
+ double-byte encodings.
+
+- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
+ guarantee that adjacent triples in the return list always describe
+ non-adjacent blocks. Previously, a pair of matching blocks could end
+ up being described by multiple adjacent triples that formed a partition
+ of the matching pair.
+
+- Bug #1498146: fix optparse to handle Unicode strings in option help,
+ description, and epilog.
+
+- Bug #1366250: minor optparse documentation error.
+
+- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
+ clarify docs.
+
+- The wsgiref package has been added to the standard library.
+
+- The functions update_wrapper() and wraps() have been added to the functools

+
+What's New in Python 2.5 alpha 2?
+=================================
+
+*Release date: 27-APR-2006*
+
+Core and builtins
+-----------------
+
+- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
+ by converting these apis from macros into exported functions again:
+
+ PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
+ PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
+ PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
+ PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
+ PyRun_String Py_CompileString
+
+- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
+
+- All uses of PyStructSequence_InitType have been changed to initialize
+ the type objects only once, even if the interpreter is initialized
+ multiple times.
+
+- Bug #1454485, array.array('u') could crash the interpreter. This was
+ due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
+ to unicode when it didn't make sense. 'u#' now requires a unicode string.
+
+- Py_UNICODE is unsigned. It was always documented as unsigned, but
+ due to a bug had a signed value in previous versions.
+
+- Patch #837242: ``id()`` of any Python object always gives a positive
+ number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
+ ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
+ never been correct to implement a ``__hash()__`` method that returns the
+ ``id()`` of an object:
+
+ def __hash__(self):
+ return id(self) # WRONG
+
+ because a hash result must be a (short) Python int but it was always
+ possible for ``id()`` to return a Python long. However, because ``id()``
+ could return negative values before, on a 32-bit box an ``id()`` result
+ was always usable as a hash value before this patch. That's no longer
+ necessarily so.
+
+- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
+ to load extension modules and now provides the dl module. As a result,
+ sys.setdlopenflags() now works correctly on these systems. (SF patch
+ #1454844)
+
+- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
+ involving generators that have paused outside of any ``try`` or ``with``
+ blocks. (In 2.5a1, a paused generator that was part of a reference
+ cycle could not be garbage collected, regardless of whether it was
+ paused in a ``try`` or ``with`` block.)
+
+Extension Modules
+-----------------
+
+- Patch #1191065: Fix preprocessor problems on systems where recvfrom
+ is a macro.
+
+- Bug #1467952: os.listdir() now correctly raises an error if readdir()
+ fails with an error condition.
+
+- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
+
+- Bug #1117761: bsddb.*open() no longer raises an exception when using
+ the cachesize parameter.
+
+- Bug #1149413: bsddb.*open() no longer raises an exception when using
+ a temporary db (file=None) with the 'n' flag to truncate on open.
+
+- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
+ as older versions cause excessive test failures.
+
+- Patch #1062014: AF_UNIX sockets under Linux have a special
+ abstract namespace that is now fully supported.
+
+Library
+-------
+
+- Bug #1223937: subprocess.CalledProcessError reports the exit status
+ of the process using the returncode attribute, instead of
+ abusing errno.
+
+- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
+ a doctest to be skipped (the code is not run, and the expected output
+ or exception is ignored).
+
+- Fixed contextlib.nested to cope with exceptions being raised and
+ caught inside exit handlers.
+
+- Updated optparse module to Optik 1.5.1 (allow numeric constants in
+ hex, octal, or binary; add ``append_const`` action; keep going if
+ gettext cannot be imported; added ``OptionParser.destroy()`` method;
+ added ``epilog`` for better help generation).
+
+- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
+ called from a thread spawned as a side effect of importing a module.
+
+- The pydoc module now supports documenting packages contained in
+ .zip or .egg files.
+
+- The pkgutil module now has several new utility functions, such
+ as ``walk_packages()`` to support working with packages that are either
+ in the filesystem or zip files.
+
+- The mailbox module can now modify and delete messages from
+ mailboxes, in addition to simply reading them. Thanks to Gregory
+ K. Johnson for writing the code, and to the 2005 Google Summer of
+ Code for funding his work.
+
+- The ``__del__`` method of class ``local`` in module ``_threading_local``
+ returned before accomplishing any of its intended cleanup.
+
+- Patch #790710: Add breakpoint command lists in pdb.
+
+- Patch #1063914: Add Tkinter.Misc.clipboard_get().
+
+- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
+
+- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
+ Windows. Bug #1469163.
+
+- The warnings, linecache, inspect, traceback, site, and doctest modules
+ were updated to work correctly with modules imported from zipfiles or
+ via other PEP 302 __loader__ objects.
+
+- Patch #1467770: Reduce usage of subprocess._active to processes which
+ the application hasn't waited on.
+
+- Patch #1462222: Fix Tix.Grid.
+
+- Fix exception when doing glob.glob('anything*/')
+
+- The pstats.Stats class accepts an optional stream keyword argument to
+ direct output to an alternate file-like object.
+
+Build
+-----
+
+- The Makefile now has a reindent target, which runs reindent.py on
+ the library.
+
+- Patch #1470875: Building Python with MS Free Compiler
+
+- Patch #1161914: Add a python-config script.
+
+- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
+ --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
+ specified. (Can be overridden by explicitly setting LINKCC.) Decouple
+ CXX from --with-cxx-main, see description in README.
+
+- Patch #1429775: Link extension modules with the shared libpython.
+
+- Fixed a libffi build problem on MIPS systems.
+
+- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
+ now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
+ and "%zu" for unsigned integers of type ``size_t``.
+
+Tests
+-----
+
+- test_contextlib now checks contextlib.nested can cope with exceptions
+ being raised and caught inside exit handlers.
+
+- test_cmd_line now checks operation of the -m and -c command switches
+
+- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
+ it separately and by hand. It also wasn't cleaning up its changes to
+ the current Decimal context.
+
+- regrtest.py now has a -M option to run tests that test the new limits of
+ containers, on 64-bit architectures. Running these tests is only sensible
+ on 64-bit machines with more than two gigabytes of memory. The argument
+ passed is the maximum amount of memory for the tests to use.
+
+Tools
+-----
+
+- Added the Python benchmark suite pybench to the Tools/ directory;
+ contributed by Marc-Andre Lemburg.
+
+Documentation
+-------------
+
+- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
+
+- PEP 343: Added Context Types section to the library reference
+ and attempted to bring other PEP 343 related documentation into
+ line with the implementation and/or python-dev discussions.
+
+- Bug #1337990: clarified that ``doctest`` does not support examples
+ requiring both expected output and an exception.
+
+
+What's New in Python 2.5 alpha 1?
+=================================
+
+*Release date: 05-APR-2006*
+
+Core and builtins
+-----------------
+
+- PEP 338: -m command line switch now delegates to runpy.run_module
+ allowing it to support modules in packages and zipfiles
+
+- On Windows, .DLL is not an accepted file name extension for
+ extension modules anymore; extensions are only found if they
+ end in .PYD.
+
+- Bug #1421664: sys.stderr.encoding is now set to the same value as
+ sys.stdout.encoding.
+
+- __import__ accepts keyword arguments.
+
+- Patch #1460496: round() now accepts keyword arguments.
+
+- Fixed bug #1459029 - unicode reprs were double-escaped.
+
+- Patch #1396919: The system scope threads are reenabled on FreeBSD
+ 5.4 and later versions.
+
+- Bug #1115379: Compiling a Unicode string with an encoding declaration
+ now gives a SyntaxError.
+
+- Previously, Python code had no easy way to access the contents of a
+ cell object. Now, a ``cell_contents`` attribute has been added
+ (closes patch #1170323).
+
+- Patch #1123430: Python's small-object allocator now returns an arena to
+ the system ``free()`` when all memory within an arena becomes unused
+ again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
+ freed. Some applications will see a drop in virtual memory size now,
+ especially long-running applications that, from time to time, temporarily
+ use a large number of small objects. Note that when Python returns an
+ arena to the platform C's ``free()``, there's no guarantee that the
+ platform C library will in turn return that memory to the operating system.
+ The effect of the patch is to stop making that impossible, and in tests it
+ appears to be effective at least on Microsoft C and gcc-based systems.
+ Thanks to Evan Jones for hard work and patience.
+
+- Patch #1434038: property() now uses the getter's docstring if there is
+ no "doc" argument given. This makes it possible to legitimately use
+ property() as a decorator to produce a read-only property.
+
+- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
+ nb_index slot to the PyNumberMethods struct. The slot is consulted instead
+ of requiring an int or long in slicing and a few other contexts, enabling
+ other objects (e.g. Numeric Python's integers) to be used as slice indices.
+
+- Fixed various bugs reported by Coverity's Prevent tool.
+
+- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
+ new exception base class, BaseException, which has a new message attribute.
+ KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
+ Raising a string exception now raises a DeprecationWarning.
+
+- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
+ explicitly relative, using 'from .module import name' to mean 'from the same
+ package as this module is in. Imports without dots still default to the
+ old relative-then-absolute, unless 'from __future__ import
+ absolute_import' is used.
+
+- Properly check if 'warnings' raises an exception (usually when a filter set
+ to "error" is triggered) when raising a warning for raising string
+ exceptions.
+
+- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
+ The name was removed from Include/code.h.
+
+- PEP 308: conditional expressions were added: (x if cond else y).
+
+- Patch 1433928:
+ - The copy module now "copies" function objects (as atomic objects).
+ - dict.__getitem__ now looks for a __missing__ hook before raising
+ KeyError.
+
+- PEP 343: with statement implemented. Needs ``from __future__ import
+ with_statement``. Use of 'with' as a variable will generate a warning.
+ Use of 'as' as a variable will also generate a warning (unless it's
+ part of an import statement).
+ The following objects have __context__ methods:
+ - The built-in file type.
+ - The thread.LockType type.
+ - The following types defined by the threading module:
+ Lock, RLock, Condition, Semaphore, BoundedSemaphore.
+ - The decimal.Context class.
+
+- Fix the encodings package codec search function to only search
+ inside its own package. Fixes problem reported in patch #1433198.
+
+ Note: Codec packages should implement and register their own
+ codec search function. PEP 100 has the details.
+
+- PEP 353: Using ``Py_ssize_t`` as the index type.
+
+- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
+ info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
+ now allow Python to make use of memory blocks exceeding 2**32 bytes for
+ some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
+ to 4-byte allocations before.
+
+- Patch #1400181, fix unicode string formatting to not use the locale.
+ This is how string objects work. u'%f' could use , instead of .
+ for the decimal point. Now both strings and unicode always use periods.
+
+- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
+ configure would break checking curses.h.
+
+- Bug #959576: The pwd module is now builtin. This allows Python to be
+ built on UNIX platforms without $HOME set.
+
+- Bug #1072182, fix some potential problems if characters are signed.
+
+- Bug #889500, fix line number on SyntaxWarning for global declarations.
+
+- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
+
+- Support for converting hex strings to floats no longer works.
+ This was not portable. float('0x3') now raises a ValueError.
+
+- Patch #1382163: Expose Subversion revision number to Python. New C API
+ function Py_GetBuildNumber(). New attribute sys.subversion. Build number
+ is now displayed in interactive prompt banner.
+
+- Implementation of PEP 341 - Unification of try/except and try/finally.
+ "except" clauses can now be written together with a "finally" clause in
+ one try statement instead of two nested ones. Patch #1355913.
+
+- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
+ now encodes backslash correctly.
+
+- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
+
+- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
+ and long longs.
+
+- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
+ It was possible for dlerror() to return a NULL pointer, so
+ it will now use a default error message in this case.
+
+- Replaced most Unicode charmap codecs with new ones using the
+ new Unicode translate string feature in the builtin charmap
+ codec; the codecs were created from the mapping tables available
+ at ftp.unicode.org and contain a few updates (e.g. the Mac OS
+ encodings now include a mapping for the Apple logo)
+
+- Added a few more codecs for Mac OS encodings
+
+- Sped up some Unicode operations.
+
+- A new AST parser implementation was completed. The abstract
+ syntax tree is available for read-only (non-compile) access
+ to Python code; an _ast module was added.
+
+- SF bug #1167751: fix incorrect code being produced for generator expressions.
+ The following code now raises a SyntaxError: foo(a = i for i in range(10))
+
+- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
+
+- SF Bug #887946: fix segfault when redirecting stdin from a directory.
+ Provide a warning when a directory is passed on the command line.
+
+- Fix segfault with invalid coding.
+
+- SF bug #772896: unknown encoding results in MemoryError.
+
+- All iterators now have a Boolean value of True. Formerly, some iterators
+ supported a __len__() method which evaluated to False when the iterator
+ was empty.
+
+- On 64-bit platforms, when __len__() returns a value that cannot be
+ represented as a C int, raise OverflowError.
+
+- test__locale is skipped on OS X < 10.4 (only partial locale support is
+ present).
+
+- SF bug #893549: parsing keyword arguments was broken with a few format
+ codes.
+
+- Changes donated by Elemental Security to make it work on AIX 5.3
+ with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
+ bug #105470: test_pwd fails on 64bit system (Opteron).
+
+- Changes donated by Elemental Security to make it work on HP-UX 11 on
+ Itanium2 with HP's 64-bit compiler (SF patch #1225212).
+
+- Disallow keyword arguments for type constructors that don't use them
+ (fixes bug #1119418).
+
+- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
+
+- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
+ exceptions that cause a function to exit.
+
+- The implementation of set() and frozenset() was revised to use its
+ own internal data structure. Memory consumption is reduced by 1/3
+ and there are modest speed-ups as well. The API is unchanged.
+
+- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
+
+- SF bug #1229429: PyObject_CallMethod failed to decrement some
+ reference counts in some error exit cases.
+
+- SF bug #1185883: Python's small-object memory allocator took over
+ a block managed by the platform C library whenever a realloc specified
+ a small new size. However, there's no portable way to know then how
+ much of the address space following the pointer is valid, so there's no
+ portable way to copy data from the C-managed block into Python's
+ small-object space without risking a memory fault. Python's small-object
+ realloc now leaves such blocks under the control of the platform C
+ realloc.
+
+- SF bug #1232517: An overflow error was not detected properly when
+ attempting to convert a large float to an int in os.utime().
+
+- SF bug #1224347: hex longs now print with lowercase letters just
+ like their int counterparts.
+
+- SF bug #1163563: the original fix for bug #1010677 ("thread Module
+ Breaks PyGILState_Ensure()") broke badly in the case of multiple
+ interpreter states; back out that fix and do a better job (see
+ http://mail.python.org/pipermail/python-dev/2005-June/054258.html
+ for a longer write-up of the problem).
+
+- SF patch #1180995: marshal now uses a binary format by default when
+ serializing floats.
+
+- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
+ the routines that promise to produce IEEE 754 binary representations
+ of floats now simply copy bytes around.
+
+- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
+ 278.
+
+- patch #1109424: int, long, float, complex, and unicode now check for the
+ proper magic slot for type conversions when subclassed. Previously the
+ magic slot was ignored during conversion. Semantics now match the way
+ subclasses of str always behaved. int/long/float, conversion of an instance
+ to the base class has been moved to the proper nb_* magic slot and out of
+ PyNumber_*().
+ Thanks Walter D�rwald.
+
+- Descriptors defined in C with a PyGetSetDef structure, where the setter is
+ NULL, now raise an AttributeError when attempting to set or delete the
+ attribute. Previously a TypeError was raised, but this was inconsistent
+ with the equivalent pure-Python implementation.
+
+- It is now safe to call PyGILState_Release() before
+ PyEval_InitThreads() (note that if there is reason to believe there
+ are multiple threads around you still must call PyEval_InitThreads()
+ before using the Python API; this fix is for extension modules that
+ have no way of knowing if Python is multi-threaded yet).
+
+- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
+ disabled caused a crash.
+
+- Bug #1165306: instancemethod_new allowed the creation of a method
+ with im_class == im_self == NULL, which caused a crash when called.
+
+- Move exception finalisation later in the shutdown process - this
+ fixes the crash seen in bug #1165761
+
+- Added two new builtins, any() and all().
+
+- Defining a class with empty parentheses is now allowed
+ (e.g., ``class C(): pass`` is no longer a syntax error).
+ Patch #1176012 added support to the 'parser' module and 'compiler' package
+ (thanks to logistix for that added support).
+
+- Patch #1115086: Support PY_LONGLONG in structmember.
+
+- Bug #1155938: new style classes did not check that __init__() was
+ returning None.
+
+- Patch #802188: Report characters after line continuation character
+ ('\') with a specific error message.
+
+- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
+
+- Bug #1124295: the __name__ attribute of file objects was
+ inadvertently made inaccessible in restricted mode.
+
+- Bug #1074011: closing sys.std{out,err} now causes a flush() and
+ an ferror() call.
+
+- min() and max() now support key= arguments with the same meaning as in
+ list.sort().
+
+- The peephole optimizer now performs simple constant folding in expressions:
+ (2+3) --> (5).
+
+- set and frozenset objects can now be marshalled. SF #1098985.
+
+- Bug #1077106: Poor argument checking could cause memory corruption
+ in calls to os.read().
+
+- The parser did not complain about future statements in illegal
+ positions. It once again reports a syntax error if a future
+ statement occurs after anything other than a doc string.
+
+- Change the %s format specifier for str objects so that it returns a
+ unicode instance if the argument is not an instance of basestring and
+ calling __str__ on the argument returns a unicode instance.
+
+- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
+ current thread state when the auto-GIL-state machinery knows about
+ it (since the thread state is being deleted, continuing to remember it
+ can't help, but can hurt if another thread happens to get created with
+ the same thread id).
+

+
+- Patch #1180695: Add nanosecond stat resolution, and st_gen,
+ st_birthtime for FreeBSD.
+
+- Patch #1231069: The fcntl.ioctl function now uses the 'I' code for

+ implementation treated all integer values except 1 as false.
+
+- Bug #1194181: bz2.BZ2File didn't handle mode 'U' correctly.

+ database.
+
+- stat_float_times is now True.
+
+- array.array objects are now picklable.
+
+- the cPickle module no longer accepts the deprecated None option in the
+ args tuple returned by __reduce__().
+
+- itertools.islice() now accepts None for the start and step arguments.
+ This allows islice() to work more readily with slices:
+ islice(s.start, s.stop, s.step)
+
+- datetime.datetime() now has a strptime class method which can be used to
+ create datetime object using a string and format.
+
+- Patch #1117961: Replace the MD5 implementation from RSA Data Security Inc
+ with the implementation from http://sourceforge.net/projects/libmd5-rfc/.
+
+Library
+-------
+
+- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
+ been renamed to have only a single underscore prefix. This was done to
+ make subclassing easier.
+
+- PEP 338: new module runpy defines a run_module function to support
+ executing modules which provide access to source code or a code object
+ via the PEP 302 import mechanisms.

+ now sport attributes that provide access to the parts of the result.
+
+- Patch #1462498: sgmllib now handles entity and character references
+ in attribute values.
+
+- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
+ a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
+ later to build this - if you have an earlier version, the C extension
+ module will not be built.
+
+- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
+ aren't officially supported here, and trying to use them will probably
+ raise an exception some day. But dicts have been allowed, and "mostly
+ worked", so support for them won't go away without warning.
+
+- Bug #1445068: getpass.getpass() can now be given an explicit stream
+ argument to specify where to write the prompt.
+
+- Patch #1462313, bug #1443328: the pickle modules now can handle classes
+ that have __private names in their __slots__.
+
+- Bug #1250170: mimetools now handles socket.gethostname() failures gracefully.
+
+- patch #1457316: "setup.py upload" now supports --identity to select the
+ key to be used for signing the uploaded code.
+
+- Queue.Queue objects now support .task_done() and .join() methods
+ to make it easier to monitor when daemon threads have completed
+ processing all enqueued tasks. Patch #1455676.
+
+- popen2.Popen objects now preserve the command in a .cmd attribute.
+
+- Added the ctypes ffi package.
+
+- email 4.0 package now integrated. This is largely the same as the email 3.0
+ package that was included in Python 2.3, except that PEP 8 module names are
+ now used (e.g. mail.message instead of email.Message). The MIME classes
+ have been moved to a subpackage (e.g. email.mime.text instead of
+ email.MIMEText). The old names are still supported for now. Several
+ deprecated Message methods have been removed and lots of bugs have been
+ fixed. More details can be found in the email package documentation.
+
+- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
+ (a subclass of tuple) that provides incremental decoders and encoders
+ (a way to use stateful codecs without the stream API). Python functions
+ codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
+ as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
+ have been added.
+
+- Patch #1359365: Calling next() on a closed StringIO.String object raises
+ a ValueError instead of a StopIteration now (like file and cString.String do).
+ cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
+ called before (like file and StringIO.StringIO do).
+
+- A regrtest option -w was added to re-run failed tests in verbose mode.
+
+- Patch #1446372: quit and exit can now be called from the interactive
+ interpreter to exit.
+
+- The function get_count() has been added to the gc module, and gc.collect()
+ grew an optional 'generation' argument.
+
+- A library msilib to generate Windows Installer files, and a distutils
+ command bdist_msi have been added.
+
+- PEP 343: new module contextlib.py defines decorator @contextmanager
+ and helpful context managers nested() and closing().
+
+- The compiler package now supports future imports after the module docstring.
+
+- Bug #1413790: zipfile now sanitizes absolute archive names that are
+ not allowed by the specs.
+
+- Patch #1215184: FileInput now can be given an opening hook which can
+ be used to control how files are opened.
+
+- Patch #1212287: fileinput.input() now has a mode parameter for
+ specifying the file mode input files should be opened with.
+
+- Patch #1215184: fileinput now has a fileno() function for getting the
+ current file number.

+ in pydoc.
+
+- Patch #1412872: zipfile now sets the creator system to 3 (Unix)
+ unless the system is Win32.
+
+- Patch #1349118: urllib now supports user:pass@ style proxy
+ specifications, raises IOErrors when proxies for unsupported protocols
+ are defined, and uses the https proxy on https redirections.
+
+- Bug #902075: urllib2 now supports 'host:port' style proxy specifications.
+
+- Bug #1407902: Add support for sftp:// URIs to urlparse.
+

+
+- Bug #1394565: SimpleHTTPServer now doesn't choke on query parameters
+ any more.
+
+- Bug #1403410: The warnings module now doesn't get confused
+ when it can't find out the module name it generates a warning for.
+
+- Patch #1177307: Added a new codec utf_8_sig for UTF-8 with a BOM signature.
+
+- Patch #1157027: cookielib mishandles RFC 2109 cookies in Netscape mode
+
+- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
+ LoadError as documented, instead of IOError. For compatibility,
+ LoadError subclasses IOError.
+
+- Added the hashlib module. It provides secure hash functions for MD5 and
+ SHA1, 224, 256, 384, and 512. Note that recent developments make the
+ historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
+ In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
+ Ronald L. Rivest offered this advice for Python:
+
+ "The consensus of researchers in this area (at least as
+ expressed at the NIST Hash Function Workshop 10/31/05),
+ is that SHA-256 is a good choice for the time being, but
+ that research should continue, and other alternatives may
+ arise from this research. The larger SHA's also seem OK."
+
+- Added a subset of Fredrik Lundh's ElementTree package. Available
+ modules are xml.etree.ElementTree, xml.etree.ElementPath, and
+ xml.etree.ElementInclude, from ElementTree 1.2.6.
+

+ ContentTooShortException, when the actually downloaded size does not
+ match the Content-Length header.
+
+- Bug #1121494: distutils.dir_utils.mkpath now accepts Unicode strings.
+
+- Bug #1178484: Return complete lines from codec stream readers
+ even if there is an exception in later lines, resulting in
+ correct line numbers for decoding errors in source code.
+
+- Bug #1192315: Disallow negative arguments to clear() in pdb.
+
+- Patch #827386: Support absolute source paths in msvccompiler.py.
+
+- Patch #1105730: Apply the new implementation of commonprefix in posixpath
+ to ntpath, macpath, os2emxpath and riscospath.
+
+- Fix a problem in Tkinter introduced by SF patch #869468: delete bogus
+ __hasattr__ and __delattr__ methods on class Tk that were breaking
+ Tkdnd.
+
+- Bug #1015140: disambiguated the term "article id" in nntplib docs and
+ docstrings to either "article number" or "message id".
+
+- Bug #1238170: threading.Thread.__init__ no longer has "kwargs={}" as a
+ parameter, but uses the usual "kwargs=None".
+
+- textwrap now processes text chunks at O(n) speed instead of O(n**2).
+ Patch #1209527 (Contributed by Connelly).
+
+- urllib2 has now an attribute 'httpresponses' mapping from HTTP status code
+ to W3C name (404 -> 'Not Found'). RFE #1216944.
+
+- Bug #1177468: Don't cache the /dev/urandom file descriptor for os.urandom,
+ as this can cause problems with apps closing all file descriptors.
+

+ it can be missing in embedded interpreters
+
+- Bug #1155638: Fix a bug which affected HTTP 0.9 responses in httplib.
+
+- Bug #1100201: Cross-site scripting was possible on BaseHTTPServer via
+ error messages.
+
+- Bug #1108948: Cookie.py produced invalid JavaScript code.
+
+- The tokenize module now detects and reports indentation errors.
+ Bug #1224621.
+
+- The tokenize module has a new untokenize() function to support a full
+ roundtrip from lexed tokens back to Python source code. In addition,
+ the generate_tokens() function now accepts a callable argument that
+ terminates by raising StopIteration.
+
+- Bug #1196315: fix weakref.WeakValueDictionary constructor.
+
+- Bug #1213894: os.path.realpath didn't resolve symlinks that were the first
+ component of the path.
+
+- Patch #1120353: The xmlrpclib module provides better, more transparent,
+ support for datetime.{datetime,date,time} objects. With use_datetime set
+ to True, applications shouldn't have to fiddle with the DateTime wrapper
+ class at all.
+
+- distutils.commands.upload was added to support uploading distribution
+ files to PyPI.
+
+- distutils.commands.register now encodes the data as UTF-8 before posting
+ them to PyPI.
+
+- decimal operator and comparison methods now return NotImplemented
+ instead of raising a TypeError when interacting with other types. This
+ allows other classes to implement __radd__ style methods and have them
+ work as expected.
+
+- Bug #1163325: Decimal infinities failed to hash. Attempting to
+ hash a NaN raised an InvalidOperation instead of a TypeError.
+
+- Patch #918101: Add tarfile open mode r|* for auto-detection of the
+ stream compression; add, for symmetry reasons, r:* as a synonym of r.

+ be exploited in various ways.
+
+- Bug #1222790: in SimpleXMLRPCServer, set the reuse-address and close-on-exec
+ flags on the HTTP listening socket.
+
+- Bug #792570: SimpleXMLRPCServer had problems if the request grew too large.
+ Fixed by reading the HTTP body in chunks instead of one big socket.read().
+
+- Patches #893642, #1039083: add allow_none, encoding arguments to
+ constructors of SimpleXMLRPCServer and CGIXMLRPCRequestHandler.
+
+- Bug #1110478: Revert os.environ.update to do putenv again.
+
+- Bug #1103844: fix distutils.install.dump_dirs() with negated options.
+
+- os.{SEEK_SET, SEEK_CUR, SEEK_END} have been added for convenience.
+
+- Enhancements to the csv module:
+
+ + Dialects are now validated by the underlying C code, better
+ reflecting its capabilities, and improving its compliance with
+ PEP 305.
+ + Dialect parameter parsing has been re-implemented to improve error
+ reporting.
+ + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
+ dictates.
+ + the parser now removes the escapechar prefix from escaped characters.
+ + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
+ types, rather than any object that can be represented as a numeric.
+ + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
+ to floats.
+ + reader now allows \r characters to be quoted (previously it only allowed
+ \n to be quoted).
+ + writer doublequote handling improved.
+ + Dialect classes passed to the module are no longer instantiated by
+ the module before being parsed (the former validation scheme required
+ this, but the mechanism was unreliable).
+ + The dialect registry now contains instances of the internal
+ C-coded dialect type, rather than references to python objects.
+ + the internal c-coded dialect type is now immutable.
+ + register_dialect now accepts the same keyword dialect specifications
+ as the reader and writer, allowing the user to register dialects
+ without first creating a dialect class.
+ + a configurable limit to the size of parsed fields has been added -
+ previously, an unmatched quote character could result in the entire
+ file being read into the field buffer before an error was reported.
+ + A new module method csv.field_size_limit() has been added that sets
+ the parser field size limit (returning the former limit). The initial
+ limit is 128kB.
+ + A line_num attribute has been added to the reader object, which tracks
+ the number of lines read from the source iterator. This is not
+ the same as the number of records returned, as records can span
+ multiple lines.
+ + reader and writer objects were not being registered with the cyclic-GC.
+ This has been fixed.
+
+- _DummyThread objects in the threading module now delete self.__block that is
+ inherited from _Thread since it uses up a lock allocated by 'thread'. The
+ lock primitives tend to be limited in number and thus should not be wasted on
+ a _DummyThread object. Fixes bug #1089632.
+
+- The imghdr module now detects Exif files.
+
+- StringIO.truncate() now correctly adjusts the size attribute.
+ (Bug #951915).
+
+- locale.py now uses an updated locale alias table (built using
+ Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
+ alias file); the encoding lookup was enhanced to use Python's
+ encoding alias table.
+
+- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
+
+- the pickle module no longer accepts the deprecated None option in the
+ args tuple returned by __reduce__().
+
+- optparse now optionally imports gettext. This allows its use in setup.py.
+
+- the pickle module no longer uses the deprecated bin parameter.
+
+- the shelve module no longer uses the deprecated binary parameter.
+
+- the pstats module no longer uses the deprecated ignore() method.
+
+- the filecmp module no longer uses the deprecated use_statcache argument.
+
+- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
+ extended or overridden by subclasses. Formerly, the subclassed method would
+ be ignored by the rest of the module. (Bug #1078905).
+
+- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
+ the same meaning as in list.sort().
+
+- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
+ once when a size argument is given. This prevents a buffer overflow in the
+ tokenizer with very long source lines.
+
+- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
+ immediately after creating the object, without any intervening
+ ``.decompress()`` calls.
+
+- The reconvert.quote function can now emit triple-quoted strings. The
+ reconvert module now has some simple documentation.
+
+- ``UserString.MutableString`` now supports negative indices in
+ ``__setitem__`` and ``__delitem__``
+
+- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
+ correctly.
+
+- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
+ ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
+ character even if the user has passed a size parameter to get a proper
+ line ending. Remove the special handling of a "\r\n" that has been split
+ between two lines.
+
+- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
+ about illegal code points. The codec now supports PEP 293 style error
+ handlers.
+
+- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
+ from the input stream, so that the output is a byte string in the correct
+ encoding instead of a unicode string.
+
+- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
+ considering it exactly like a '*'.
+
+- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
+ ``encodings.aliases``.
+
+- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
+
+- Patch #1413711: Certain patterns of differences were making difflib
+ touch the recursion limit.
+
+- Bug #947906: An object oriented interface has been added to the calendar
+ module. It's possible to generate HTML calendar now and the module can be
+ called as a script (e.g. via ``python -mcalendar``). Localized month and
+ weekday names can be ouput (even if an exotic encoding is used) using
+ special classes that use unicode.
+
+Build
+-----
+
+- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
+ by using -mieee gcc option.
+
+- Patch #1432345: Make python compile on DragonFly.
+
+- Build support for Win64-AMD64 was added.
+
+- Patch #1428494: Prefer linking against ncursesw over ncurses library.
+
+- Patch #881820: look for openpty and forkpty also in libbsd.
+
+- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
+ The zlib module is now builtin on Windows.
+
+- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
+
+- Bug #1189330: configure did not correctly determine the necessary
+ value of LINKCC if python was built with GCC 4.0.
+
+- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
+ vulnerability in zlib 1.2.1 and 1.2.2.
+
+- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
+ flags that change binary compatibility. Changes were also made to
+ distutils.sysconfig to also use the environment variable when used during
+ compilation of the interpreter and of C extensions through distutils.
+
+- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
+ and linking has changed (prebinding is now deprecated, and libcc_dynamic
+ no longer exists). This configure patch makes things right.
+
+- Bug #1158607: Build with --disable-unicode again.
+
+- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
+ defined. Discovered as a result of not being able to build on OS X.
+
+- setup.py now uses the directories specified in LDFLAGS using the -L option
+ and in CPPFLAGS using the -I option for adding library and include
+ directories, respectively, for compiling extension modules against. This has
+ led to the core being compiled using the values in CPPFLAGS. It also removes
+ the need for the special-casing of both DarwinPorts and Fink for darwin since
+ the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
+ ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
+ Fink, ``-I/opt/local/include`` for DarwinPorts).
+
+- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
+ to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
+ Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
+ Closes bug #1096244. Thanks Gregory Bond.
+
+C API
+-----
+
+- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
+ ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
+ is obtained via the ``PyObject_`` family, it must be released via the
+ ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
+ always been officially true, but when Python's small-object allocator was
+ introduced, an attempt was made to cater to a few extension modules
+ discovered at the time that obtained memory via ``PyObject_New`` but
+ released it via ``PyMem_DEL``. It's years later, and if such code still
+ exists it will fail now (probably with segfaults, but calling wrong
+ low-level memory management functions can yield many symptoms).
+
+- Added a C API for set and frozenset objects.
+
+- Removed PyRange_New().
+
+- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
+ mapping argument now. This string is used as a mapping table. Byte values
+ greater than the length of the string and 0xFFFE are treated as undefined
+ mappings.
+
+
+Tests
+-----
+
+- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
+
+- Patch #1276356: New resource "urlfetch" is implemented. This enables
+ even impatient people to run tests that require remote files.
+
+
+Documentation
+-------------
+
+- Bug #1402224: Add warning to dl docs about crashes.
+
+- Bug #1396471: Document that Windows' ftell() can return invalid
+ values for text files with UNIX-style line endings.
+
+- Bug #1274828: Document os.path.splitunc().
+
+- Bug #1190204: Clarify which directories are searched by site.py.
+
+- Bug #1193849: Clarify os.path.expanduser() documentation.
+
+- Bug #1243192: re.UNICODE and re.LOCALE affect \d, \D, \s and \S.
+
+- Bug #755617: Document the effects of os.chown() on Windows.
+
+- Patch #1180012: The documentation for modulefinder is now in the library reference.
+
+- Patch #1213031: Document that os.chown() accepts argument values of -1.
+
+- Bug #1190563: Document os.waitpid() return value with WNOHANG flag.
+
+- Bug #1175022: Correct the example code for property().
+
+- Document the IterableUserDict class in the UserDict module.
+ Closes bug #1166582.
+
+- Remove all latent references for "Macintosh" that referred to semantics for
+ Mac OS 9 and change to reflect the state for OS X.
+ Closes patch #1095802. Thanks Jack Jansen.
+
+Mac
+---
+
+
+New platforms
+-------------
+
+- FreeBSD 7 support is added.
+
+
+Tools/Demos
+-----------
+
+- Created Misc/Vim/vim_syntax.py to auto-generate a python.vim file in that
+ directory for syntax highlighting in Vim. Vim directory was added and placed
+ vimrc to it (was previous up a level).
+
+- Added two new files to Tools/scripts: pysource.py, which recursively
+ finds Python source files, and findnocoding.py, which finds Python
+ source files that need an encoding declaration.
+ Patch #784089, credits to Oleg Broytmann.
+
+- Bug #1072853: pindent.py used an uninitialized variable.
+
+- Patch #1177597: Correct Complex.__init__.
+
+- Fixed a display glitch in Pynche, which could cause the right arrow to
+ wiggle over by a pixel.
+
+

-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
--------
-
-- Fix a bug in the ``compiler`` package that caused invalid code to be
- generated for generator expressions.
-
-- The distutils version has been changed to 2.5.0. The change to
- keep it programmatically in sync with the Python version running
- the code (introduced in 2.5b3) has been reverted. It will continue
- to be maintained manually as static string literal.
-
-- If the Python part of a ctypes callback function returns None,
- and this cannot be converted to the required C type, an exception is
- printed with PyErr_WriteUnraisable. Before this change, the C
- callback returned arbitrary values to the calling code.
-
-- The __repr__ method of a NULL ctypes.py_object() no longer raises
- an exception.
-
-- uuid.UUID now has a bytes_le attribute. This returns the UUID in
- little-endian byte order for Windows. In addition, uuid.py gained some
- workarounds for clocks with low resolution, to stop the code yielding
- duplicate UUIDs.
-
-- Patch #1540892: site.py Quitter() class attempts to close sys.stdin
- before raising SystemExit, allowing IDLE to honor quit() and exit().
-
-- Bug #1224621: make tabnanny recognize IndentationErrors raised by tokenize.
-
-- Patch #1536071: trace.py should now find the full module name of a
- file correctly even on Windows.
-
-- logging's atexit hook now runs even if the rest of the module has
- already been cleaned up.
-
-- Bug #1112549, fix DoS attack on cgi.FieldStorage.
-
-- Bug #1531405, format_exception no longer raises an exception if
- str(exception) raised an exception.
-
-- Fix a bug in the ``compiler`` package that caused invalid code to be
- generated for nested functions.
-
-
-Extension Modules
------------------
-
-- Patch #1511317: don't crash on invalid hostname (alias) info.
-
-- Patch #1535500: fix segfault in BZ2File.writelines and make sure it
- raises the correct exceptions.
-
-- Patch # 1536908: enable building ctypes on OpenBSD/AMD64. The
- '-no-stack-protector' compiler flag for OpenBSD has been removed.
-
-- Patch #1532975 was applied, which fixes Bug #1533481: ctypes now
- uses the _as_parameter_ attribute when objects are passed to foreign
- function calls. The ctypes version number was changed to 1.0.1.
-
-- Bug #1530559, struct.pack raises TypeError where it used to convert.
- Passing float arguments to struct.pack when integers are expected
- now triggers a DeprecationWarning.
-
-
-Tests
------
-
-- test_socketserver should now work on cygwin and not fail sporadically
- on other platforms.
-
-- test_mailbox should now work on cygwin versions 2006-08-10 and later.
-
-- Bug #1535182: really test the xreadlines() method of bz2 objects.
-
-- test_threading now skips testing alternate thread stack sizes on
- platforms that don't support changing thread stack size.
-
-
-Documentation
--------------
-
-- Patch #1534922: unittest docs were corrected and enhanced.
-
-
-Build
------
-
-- Bug #1535502, build _hashlib on Windows, and use masm assembler
- code in OpenSSL.
-
-- Bug #1534738, win32 debug version of _msi should be _msi_d.pyd.
-
-- Bug #1530448, ctypes build failure on Solaris 10 was fixed.
-
-
-C API
------
-
-- New API for Unicode rich comparisons: PyUnicode_RichCompare()
-
-- Bug #1069160. Internal correctness changes were made to
- ``PyThreadState_SetAsyncExc()``. A test case was added, and
- the documentation was changed to state that the return value
- is always 1 (normal) or 0 (if the specified thread wasn't found).
-
-
-What's New in Python 2.5 beta 3?
-================================
-
-*Release date: 03-AUG-2006*
-
-Core and builtins
------------------
-
-- _PyWeakref_GetWeakrefCount() now returns a Py_ssize_t; it previously
- returned a long (see PEP 353).
-
-- Bug #1515471: string.replace() accepts character buffers again.
-
-- Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
- This provides the proper warning for struct.pack().
- PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
-
-- Patch #1531113: Fix augmented assignment with yield expressions.
- Also fix a SystemError when trying to assign to yield expressions.
-
-- Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
- with PEP 302. This was fixed by adding an ``imp.NullImporter`` type that is
- used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
- excessive filesystem operations during imports.
-
-- Bug #1521947: When checking for overflow, ``PyOS_strtol()`` used some
- operations on signed longs that are formally undefined by C.
- Unfortunately, at least one compiler now cares about that, so complicated
- the code to make that compiler happy again.
-
-- Bug #1524310: Properly report errors from FindNextFile in os.listdir.
-
-- Patch #1232023: Stop including current directory in search
- path on Windows.
-
-- Fix some potential crashes found with failmalloc.
-
-- Fix warnings reported by Klocwork's static analysis tool.
-
-- Bug #1512814, Fix incorrect lineno's when code within a function
- had more than 255 blank lines.
-
-- Patch #1521179: Python now accepts the standard options ``--help`` and
- ``--version`` as well as ``/?`` on Windows.
-
-- Bug #1520864: unpacking singleton tuples in a 'for' loop (for x, in) works
- again. Fixing this problem required changing the .pyc magic number.
- This means that .pyc files generated before 2.5b3 will be regenerated.
-
-- Bug #1524317: Compiling Python ``--without-threads`` failed.
- The Python core compiles again, and, in a build without threads, the
- new ``sys._current_frames()`` returns a dictionary with one entry,
- mapping the faux "thread id" 0 to the current frame.
-
-- Bug #1525447: build on MacOS X on a case-sensitive filesystem.
-
-
-Library
--------
-
-- Fix #1693149. Now you can pass several modules separated by
- comma to trace.py in the same --ignore-module option.
-
-- Correction of patch #1455898: In the mbcs decoder, set final=False
- for stream decoder, but final=True for the decode function.
-
-- os.urandom no longer masks unrelated exceptions like SystemExit or
- KeyboardInterrupt.
-
-- Bug #1525866: Don't copy directory stat times in
- shutil.copytree on Windows
-
-- Bug #1002398: The documentation for os.path.sameopenfile now correctly
- refers to file descriptors, not file objects.
-
-- The renaming of the xml package to xmlcore, and the import hackery done
- to make it appear at both names, has been removed. Bug #1511497,
- #1513611, and probably others.
-
-- Bug #1441397: The compiler module now recognizes module and function
- docstrings correctly as it did in Python 2.4.
-
-- Bug #1529297: The rewrite of doctest for Python 2.4 unintentionally
- lost that tests are sorted by name before being run. This rarely
- matters for well-written tests, but can create baffling symptoms if
- side effects from one test to the next affect outcomes. ``DocTestFinder``
- has been changed to sort the list of tests it returns.
-
-- The distutils version has been changed to 2.5.0, and is now kept
- in sync with sys.version_info[:3].
-
-- Bug #978833: Really close underlying socket in _socketobject.close.
-
-- Bug #1459963: urllib and urllib2 now normalize HTTP header names with
- title().
-
-- Patch #1525766: In pkgutil.walk_packages, correctly pass the onerror callback
- to recursive calls and call it with the failing package name.
-
-- Bug #1525817: Don't truncate short lines in IDLE's tool tips.
-
-- Patch #1515343: Fix printing of deprecated string exceptions with a
- value in the traceback module.
-
-- Resync optparse with Optik 1.5.3: minor tweaks for/to tests.
-
-- Patch #1524429: Use repr() instead of backticks in Tkinter again.
-
-- Bug #1520914: Change time.strftime() to accept a zero for any position in its
- argument tuple. For arguments where zero is illegal, the value is forced to
- the minimum value that is correct. This is to support an undocumented but
- common way people used to fill in inconsequential information in the time
- tuple pre-2.4.
-
-- Patch #1220874: Update the binhex module for Mach-O.
-
-- The email package has improved RFC 2231 support, specifically for
- recognizing the difference between encoded (name*0*=<blah>) and non-encoded
- (name*0=<blah>) parameter continuations. This may change the types of
- values returned from email.message.Message.get_param() and friends.
- Specifically in some cases where non-encoded continuations were used,
- get_param() used to return a 3-tuple of (None, None, string) whereas now it
- will just return the string (since non-encoded continuations don't have
- charset and language parts).
-
- Also, whereas % values were decoded in all parameter continuations, they are
- now only decoded in encoded parameter parts.
-
-- Bug #1517990: IDLE keybindings on MacOS X now work correctly
-
-- Bug #1517996: IDLE now longer shows the default Tk menu when a
- path browser, class browser or debugger is the frontmost window on MacOS X
-
-- Patch #1520294: Support for getset and member descriptors in types.py,
- inspect.py, and pydoc.py. Specifically, this allows for querying the type
- of an object against these built-in types and more importantly, for getting
- their docstrings printed in the interactive interpreter's help() function.
-
-
-Extension Modules
------------------
-
-- Patch #1519025 and bug #926423: If a KeyboardInterrupt occurs during
- a socket operation on a socket with a timeout, the exception will be
- caught correctly. Previously, the exception was not caught.
-
-- Patch #1529514: The _ctypes extension is now compiled on more
- openbsd target platforms.
-
-- The ``__reduce__()`` method of the new ``collections.defaultdict`` had
- a memory leak, affecting pickles and deep copies.
-
-- Bug #1471938: Fix curses module build problem on Solaris 8; patch by
- Paul Eggert.
-
-- Patch #1448199: Release interpreter lock in _winreg.ConnectRegistry.
-
-- Patch #1521817: Index range checking on ctypes arrays containing
- exactly one element enabled again. This allows iterating over these
- arrays, without the need to check the array size before.
-
-- Bug #1521375: When the code in ctypes.util.find_library was
- run with root privileges, it could overwrite or delete
- /dev/null in certain cases; this is now fixed.
-
-- Bug #1467450: On Mac OS X 10.3, RTLD_GLOBAL is now used as the
- default mode for loading shared libraries in ctypes.
-
-- Because of a misspelled preprocessor symbol, ctypes was always
- compiled without thread support; this is now fixed.
-
-- pybsddb Bug #1527939: bsddb module DBEnv dbremove and dbrename
- methods now allow their database parameter to be None as the
- sleepycat API allows.
-
-- Bug #1526460: Fix socketmodule compile on NetBSD as it has a different
- bluetooth API compared with Linux and FreeBSD.
-
-Tests
------
-
-- Bug #1501330: Change test_ossaudiodev to be much more tolerant in terms of
- how long the test file should take to play. Now accepts taking 2.93 secs
- (exact time) +/- 10% instead of the hard-coded 3.1 sec.
-
-- Patch #1529686: The standard tests ``test_defaultdict``, ``test_iterlen``,
- ``test_uuid`` and ``test_email_codecs`` didn't actually run any tests when
- run via ``regrtest.py``. Now they do.
-
-Build
------
-
-- Bug #1439538: Drop usage of test -e in configure as it is not portable.
-
-Mac
----
-
-- PythonLauncher now works correctly when the path to the script contains
- characters that are treated specially by the shell (such as quotes).
-
-- Bug #1527397: PythonLauncher now launches scripts with the working directory
- set to the directory that contains the script instead of the user home
- directory. That latter was an implementation accident and not what users
- expect.
-
-
-What's New in Python 2.5 beta 2?
-================================
-
-*Release date: 11-JUL-2006*
-
-Core and builtins
------------------
-
-- Bug #1441486: The literal representation of -(sys.maxint - 1)
- again evaluates to a int object, not a long.
-
-- Bug #1501934: The scope of global variables that are locally assigned
- using augmented assignment is now correctly determined.
-
-- Bug #927248: Recursive method-wrapper objects can now safely
- be released.
-
-- Bug #1417699: Reject locale-specific decimal point in float()
- and atof().
-
-- Bug #1511381: codec_getstreamcodec() in codec.c is corrected to
- omit a default "error" argument for NULL pointer. This allows
- the parser to take a codec from cjkcodecs again.
-
-- Bug #1519018: 'as' is now validated properly in import statements.
-
-- On 64 bit systems, int literals that use less than 64 bits are
- now ints rather than longs.
-
-- Bug #1512814, Fix incorrect lineno's when code at module scope
- started after line 256.
-
-- New function ``sys._current_frames()`` returns a dict mapping thread
- id to topmost thread stack frame. This is for expert use, and is
- especially useful for debugging application deadlocks. The functionality
- was previously available in Fazal Majid's ``threadframe`` extension
- module, but it wasn't possible to do this in a wholly threadsafe way from
- an extension.

-What's New in Python 2.5 beta 1?
-================================
-
-*Release date: 20-JUN-2006*
-
-Core and builtins
------------------
-
-- Patch #1507676: Error messages returned by invalid abstract object operations
- (such as iterating over an integer) have been improved and now include the
- type of the offending object to help with debugging.
-
-- Bug #992017: A classic class that defined a __coerce__() method that returned
- its arguments swapped would infinitely recurse and segfault the interpreter.
-
-- Fix the socket tests so they can be run concurrently.
-
-- Removed 5 integers from C frame objects (PyFrameObject).
- f_nlocals, f_ncells, f_nfreevars, f_stack_size, f_restricted.
-
-- Bug #532646: object.__call__() will continue looking for the __call__
- attribute on objects until one without one is found. This leads to recursion
- when you take a class and set its __call__ attribute to an instance of the
- class. Originally fixed for classic classes, but this fix is for new-style.
- Removes the infinite_rec_3 crasher.
-
-- The string and unicode methods startswith() and endswith() now accept
- a tuple of prefixes/suffixes to look for. Implements RFE #1491485.
-
-- Buffer objects, at the C level, never used the char buffer
- implementation even when the char buffer for the wrapped object was
- explicitly requested (originally returned the read or write buffer).
- Now a TypeError is raised if the char buffer is not present but is
- requested.
-
-- Patch #1346214: Statements like "if 0: suite" are now again optimized
- away like they were in Python 2.4.
-
-- Builtin exceptions are now full-blown new-style classes instead of
- instances pretending to be classes, which speeds up exception handling
- by about 80% in comparison to 2.5a2.
-
-- Patch #1494554: Update unicodedata.numeric and unicode.isnumeric to
- Unicode 4.1.
-
-- Patch #921466: sys.path_importer_cache is now used to cache valid and
- invalid file paths for the built-in import machinery which leads to
- fewer open calls on startup.
-
-- Patch #1442927: ``long(str, base)`` is now up to 6x faster for non-power-
- of-2 bases. The largest speedup is for inputs with about 1000 decimal
- digits. Conversion from non-power-of-2 bases remains quadratic-time in
- the number of input digits (it was and remains linear-time for bases
- 2, 4, 8, 16 and 32).
-
-- Bug #1334662: ``int(string, base)`` could deliver a wrong answer
- when ``base`` was not 2, 4, 8, 10, 16 or 32, and ``string`` represented
- an integer close to ``sys.maxint``. This was repaired by patch
- #1335972, which also gives a nice speedup.
-
-- Patch #1337051: reduced size of frame objects.
-
-- PyErr_NewException now accepts a tuple of base classes as its
- "base" parameter.
-
-- Patch #876206: function call speedup by retaining allocated frame
- objects.
-
-- Bug #1462152: file() now checks more thoroughly for invalid mode
- strings and removes a possible "U" before passing the mode to the
- C library function.
-
-- Patch #1488312, Fix memory alignment problem on SPARC in unicode
-
-- Bug #1487966: Fix SystemError with conditional expression in assignment
-
-- WindowsError now has two error code attributes: errno, which carries
- the error values from errno.h, and winerror, which carries the error
- values from winerror.h. Previous versions put the winerror.h values
- (from GetLastError()) into the errno attribute.
-
-- Patch #1475845: Raise IndentationError for unexpected indent.
-
-- Patch #1479181: split open() and file() from being aliases for each other.
-
-- Patch #1497053 & bug #1275608: Exceptions occurring in ``__eq__()``
- methods were always silently ignored by dictionaries when comparing keys.
- They are now passed through (except when using the C API function
- ``PyDict_GetItem()``, whose semantics did not change).
-
-- Bug #1456209: In some obscure cases it was possible for a class with a
- custom ``__eq__()`` method to confuse dict internals when class instances
- were used as a dict's keys and the ``__eq__()`` method mutated the dict.
- No, you don't have any code that did this ;-)
-
-Extension Modules
------------------
-
-- Bug #1295808: expat symbols should be namespaced in pyexpat
-
-- Patch #1462338: Upgrade pyexpat to expat 2.0.0
-
-- Change binascii.hexlify to accept a read-only buffer instead of only a char
- buffer and actually follow its documentation.
-
-- Fixed a potentially invalid memory access of CJKCodecs' shift-jis decoder.
-
-- Patch #1478788 (modified version): The functional extension module has
- been renamed to _functools and a functools Python wrapper module added.
- This provides a home for additional function related utilities that are
- not specifically about functional programming. See PEP 309.
-
-- Patch #1493701: performance enhancements for struct module.
-
-- Patch #1490224: time.altzone is now set correctly on Cygwin.
-
-- Patch #1435422: zlib's compress and decompress objects now have a
- copy() method.
-
-- Patch #1454481: thread stack size is now tunable at runtime for thread
- enabled builds on Windows and systems with Posix threads support.
-
-- On Win32, os.listdir now supports arbitrarily-long Unicode path names
- (up to the system limit of 32K characters).
-
-- Use Win32 API to implement os.{access,chdir,chmod,mkdir,remove,rename,rmdir,utime}.
- As a result, these functions now raise WindowsError instead of OSError.
-
-- ``time.clock()`` on Win64 should use the high-performance Windows
- ``QueryPerformanceCounter()`` now (as was already the case on 32-bit
- Windows platforms).
-
-- Calling Tk_Init twice is refused if the first call failed as that
- may deadlock.
-
-- bsddb: added the DB_ARCH_REMOVE flag and fixed db.DBEnv.log_archive() to
- accept it without potentially using an uninitialized pointer.
-
-- bsddb: added support for the DBEnv.log_stat() and DBEnv.lsn_reset() methods
- assuming BerkeleyDB >= 4.0 and 4.4 respectively. [pybsddb project SF
- patch numbers 1494885 and 1494902]
-
-- bsddb: added an interface for the BerkeleyDB >= 4.3 DBSequence class.
- [pybsddb project SF patch number 1466734]
-
-- bsddb: fix DBCursor.pget() bug with keyword argument names when no data
- parameter is supplied. [SF pybsddb bug #1477863]
-
-- bsddb: the __len__ method of a DB object has been fixed to return correct
- results. It could previously incorrectly return 0 in some cases.
- Fixes SF bug 1493322 (pybsddb bug 1184012).
-
-- bsddb: the bsddb.dbtables Modify method now raises the proper error and
- aborts the db transaction safely when a modifier callback fails.
- Fixes SF python patch/bug #1408584.
-
-- bsddb: multithreaded DB access using the simple bsddb module interface
- now works reliably. It has been updated to use automatic BerkeleyDB
- deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
- database calls that would previously deadlock. [SF python bug #775414]
-
-- Patch #1446489: add support for the ZIP64 extensions to zipfile.
-
-- Patch #1506645: add Python wrappers for the curses functions
- is_term_resized, resize_term and resizeterm.
-
-Library
--------
-
-- Patch #815924: Restore ability to pass type= and icon= in tkMessageBox
- functions.
-
-- Patch #812986: Update turtle output even if not tracing.
-
-- Patch #1494750: Destroy master after deleting children in
- Tkinter.BaseWidget.
-
-- Patch #1096231: Add ``default`` argument to Tkinter.Wm.wm_iconbitmap.
-
-- Patch #763580: Add name and value arguments to Tkinter variable
- classes.
-
-- Bug #1117556: SimpleHTTPServer now tries to find and use the system's
- mime.types file for determining MIME types.
-
-- Bug #1339007: Shelf objects now don't raise an exception in their
- __del__ method when initialization failed.
-
-- Patch #1455898: The MBCS codec now supports the incremental mode for
- double-byte encodings.
-
-- ``difflib``'s ``SequenceMatcher.get_matching_blocks()`` was changed to
- guarantee that adjacent triples in the return list always describe
- non-adjacent blocks. Previously, a pair of matching blocks could end
- up being described by multiple adjacent triples that formed a partition
- of the matching pair.
-
-- Bug #1498146: fix optparse to handle Unicode strings in option help,
- description, and epilog.
-
-- Bug #1366250: minor optparse documentation error.
-
-- Bug #1361643: fix textwrap.dedent() so it handles tabs appropriately;
- clarify docs.
-
-- The wsgiref package has been added to the standard library.
-
-- The functions update_wrapper() and wraps() have been added to the functools
- module. These make it easier to copy relevant metadata from the original
- function when writing wrapper functions.
-
-- The optional ``isprivate`` argument to ``doctest.testmod()``, and the
- ``doctest.is_private()`` function, both deprecated in 2.4, were removed.
-
-- Patch #1359618: Speed up charmap encoder by using a trie structure
- for lookup.
-
-- The functions in the ``pprint`` module now sort dictionaries by key
- before computing the display. Before 2.5, ``pprint`` sorted a dictionary
- if and only if its display required more than one line, although that
- wasn't documented. The new behavior increases predictability; e.g.,
- using ``pprint.pprint(a_dict)`` in a doctest is now reliable.
-
-- Patch #1497027: try HTTP digest auth before basic auth in urllib2
- (thanks for J. J. Lee).
-
-- Patch #1496206: improve urllib2 handling of passwords with respect to
- default HTTP and HTTPS ports.
-
-- Patch #1080727: add "encoding" parameter to doctest.DocFileSuite.
-
-- Patch #1281707: speed up gzip.readline.
-
-- Patch #1180296: Two new functions were added to the locale module:
- format_string() to get the effect of "format % items" but locale-aware,
- and currency() to format a monetary number with currency sign.
-
-- Patch #1486962: Several bugs in the turtle Tk demo module were fixed
- and several features added, such as speed and geometry control.
-
-- Patch #1488881: add support for external file objects in bz2 compressed
- tarfiles.
-
-- Patch #721464: pdb.Pdb instances can now be given explicit stdin and
- stdout arguments, making it possible to redirect input and output
- for remote debugging.
-
-- Patch #1484695: Update the tarfile module to version 0.8. This fixes
- a couple of issues, notably handling of long file names using the
- GNU LONGNAME extension.
-
-- Patch #1478292. ``doctest.register_optionflag(name)`` shouldn't create a
- new flag when ``name`` is already the name of an option flag.
-
-- Bug #1385040: don't allow "def foo(a=1, b): pass" in the compiler
- package.
-
-- Patch #1472854: make the rlcompleter.Completer class usable on non-
- UNIX platforms.
-
-- Patch #1470846: fix urllib2 ProxyBasicAuthHandler.
-
-- Bug #1472827: correctly escape newlines and tabs in attribute values in
- the saxutils.XMLGenerator class.

-What's New in Python 2.5 alpha 2?
-=================================
-
-*Release date: 27-APR-2006*
-
-Core and builtins
------------------
-
-- Bug #1465834: 'bdist_wininst preinstall script support' was fixed
- by converting these apis from macros into exported functions again:
-
- PyParser_SimpleParseFile PyParser_SimpleParseString PyRun_AnyFile
- PyRun_AnyFileEx PyRun_AnyFileFlags PyRun_File PyRun_FileEx
- PyRun_FileFlags PyRun_InteractiveLoop PyRun_InteractiveOne
- PyRun_SimpleFile PyRun_SimpleFileEx PyRun_SimpleString
- PyRun_String Py_CompileString
-
-- Under COUNT_ALLOCS, types are not necessarily immortal anymore.
-
-- All uses of PyStructSequence_InitType have been changed to initialize
- the type objects only once, even if the interpreter is initialized
- multiple times.
-
-- Bug #1454485, array.array('u') could crash the interpreter. This was
- due to PyArgs_ParseTuple(args, 'u#', ...) trying to convert buffers (strings)
- to unicode when it didn't make sense. 'u#' now requires a unicode string.
-
-- Py_UNICODE is unsigned. It was always documented as unsigned, but
- due to a bug had a signed value in previous versions.
-
-- Patch #837242: ``id()`` of any Python object always gives a positive
- number now, which might be a long integer. ``PyLong_FromVoidPtr`` and
- ``PyLong_AsVoidPtr`` have been changed accordingly. Note that it has
- never been correct to implement a ``__hash()__`` method that returns the
- ``id()`` of an object:
-
- def __hash__(self):
- return id(self) # WRONG
-
- because a hash result must be a (short) Python int but it was always
- possible for ``id()`` to return a Python long. However, because ``id()``
- could return negative values before, on a 32-bit box an ``id()`` result
- was always usable as a hash value before this patch. That's no longer
- necessarily so.
-
-- Python on OS X 10.3 and above now uses dlopen() (via dynload_shlib.c)
- to load extension modules and now provides the dl module. As a result,
- sys.setdlopenflags() now works correctly on these systems. (SF patch
- #1454844)
-
-- Patch #1463867: enhanced garbage collection to allow cleanup of cycles
- involving generators that have paused outside of any ``try`` or ``with``
- blocks. (In 2.5a1, a paused generator that was part of a reference
- cycle could not be garbage collected, regardless of whether it was
- paused in a ``try`` or ``with`` block.)
-
-Extension Modules
------------------
-
-- Patch #1191065: Fix preprocessor problems on systems where recvfrom
- is a macro.
-
-- Bug #1467952: os.listdir() now correctly raises an error if readdir()
- fails with an error condition.
-
-- Fixed bsddb.db.DBError derived exceptions so they can be unpickled.
-
-- Bug #1117761: bsddb.*open() no longer raises an exception when using
- the cachesize parameter.
-
-- Bug #1149413: bsddb.*open() no longer raises an exception when using
- a temporary db (file=None) with the 'n' flag to truncate on open.
-
-- Bug #1332852: bsddb module minimum BerkeleyDB version raised to 3.3
- as older versions cause excessive test failures.
-
-- Patch #1062014: AF_UNIX sockets under Linux have a special
- abstract namespace that is now fully supported.
-
-Library
--------
-
-- Bug #1223937: subprocess.CalledProcessError reports the exit status
- of the process using the returncode attribute, instead of
- abusing errno.
-
-- Patch #1475231: ``doctest`` has a new ``SKIP`` option, which causes
- a doctest to be skipped (the code is not run, and the expected output
- or exception is ignored).
-
-- Fixed contextlib.nested to cope with exceptions being raised and
- caught inside exit handlers.
-
-- Updated optparse module to Optik 1.5.1 (allow numeric constants in
- hex, octal, or binary; add ``append_const`` action; keep going if
- gettext cannot be imported; added ``OptionParser.destroy()`` method;
- added ``epilog`` for better help generation).
-
-- Bug #1473760: ``tempfile.TemporaryFile()`` could hang on Windows, when
- called from a thread spawned as a side effect of importing a module.
-
-- The pydoc module now supports documenting packages contained in
- .zip or .egg files.
-
-- The pkgutil module now has several new utility functions, such
- as ``walk_packages()`` to support working with packages that are either
- in the filesystem or zip files.
-
-- The mailbox module can now modify and delete messages from
- mailboxes, in addition to simply reading them. Thanks to Gregory
- K. Johnson for writing the code, and to the 2005 Google Summer of
- Code for funding his work.
-
-- The ``__del__`` method of class ``local`` in module ``_threading_local``
- returned before accomplishing any of its intended cleanup.
-
-- Patch #790710: Add breakpoint command lists in pdb.
-
-- Patch #1063914: Add Tkinter.Misc.clipboard_get().
-
-- Patch #1191700: Adjust column alignment in bdb breakpoint lists.
-
-- SimpleXMLRPCServer relied on the fcntl module, which is unavailable on
- Windows. Bug #1469163.
-
-- The warnings, linecache, inspect, traceback, site, and doctest modules
- were updated to work correctly with modules imported from zipfiles or
- via other PEP 302 __loader__ objects.
-
-- Patch #1467770: Reduce usage of subprocess._active to processes which
- the application hasn't waited on.
-
-- Patch #1462222: Fix Tix.Grid.
-
-- Fix exception when doing glob.glob('anything*/')
-
-- The pstats.Stats class accepts an optional stream keyword argument to
- direct output to an alternate file-like object.
-
-Build
------
-
-- The Makefile now has a reindent target, which runs reindent.py on
- the library.
-
-- Patch #1470875: Building Python with MS Free Compiler
-
-- Patch #1161914: Add a python-config script.
-
-- Patch #1324762:Remove ccpython.cc; replace --with-cxx with
- --with-cxx-main. Link with C++ compiler only if --with-cxx-main was
- specified. (Can be overridden by explicitly setting LINKCC.) Decouple
- CXX from --with-cxx-main, see description in README.
-
-- Patch #1429775: Link extension modules with the shared libpython.
-
-- Fixed a libffi build problem on MIPS systems.
-
-- ``PyString_FromFormat``, ``PyErr_Format``, and ``PyString_FromFormatV``
- now accept formats "%u" for unsigned ints, "%lu" for unsigned longs,
- and "%zu" for unsigned integers of type ``size_t``.
-
-Tests
------
-
-- test_contextlib now checks contextlib.nested can cope with exceptions
- being raised and caught inside exit handlers.
-
-- test_cmd_line now checks operation of the -m and -c command switches
-
-- The test_contextlib test in 2.5a1 wasn't actually run unless you ran
- it separately and by hand. It also wasn't cleaning up its changes to
- the current Decimal context.
-
-- regrtest.py now has a -M option to run tests that test the new limits of
- containers, on 64-bit architectures. Running these tests is only sensible
- on 64-bit machines with more than two gigabytes of memory. The argument
- passed is the maximum amount of memory for the tests to use.
-
-Tools
------
-
-- Added the Python benchmark suite pybench to the Tools/ directory;
- contributed by Marc-Andre Lemburg.
-
-Documentation
--------------
-
-- Patch #1473132: Improve docs for ``tp_clear`` and ``tp_traverse``.
-
-- PEP 343: Added Context Types section to the library reference
- and attempted to bring other PEP 343 related documentation into
- line with the implementation and/or python-dev discussions.
-
-- Bug #1337990: clarified that ``doctest`` does not support examples
- requiring both expected output and an exception.
-
-
-What's New in Python 2.5 alpha 1?
-=================================
-
-*Release date: 05-APR-2006*
-
-Core and builtins
------------------
-
-- PEP 338: -m command line switch now delegates to runpy.run_module
- allowing it to support modules in packages and zipfiles
-
-- On Windows, .DLL is not an accepted file name extension for
- extension modules anymore; extensions are only found if they
- end in .PYD.
-
-- Bug #1421664: sys.stderr.encoding is now set to the same value as
- sys.stdout.encoding.
-
-- __import__ accepts keyword arguments.
-
-- Patch #1460496: round() now accepts keyword arguments.
-
-- Fixed bug #1459029 - unicode reprs were double-escaped.
-
-- Patch #1396919: The system scope threads are reenabled on FreeBSD
- 5.4 and later versions.
-
-- Bug #1115379: Compiling a Unicode string with an encoding declaration
- now gives a SyntaxError.
-
-- Previously, Python code had no easy way to access the contents of a
- cell object. Now, a ``cell_contents`` attribute has been added
- (closes patch #1170323).
-
-- Patch #1123430: Python's small-object allocator now returns an arena to
- the system ``free()`` when all memory within an arena becomes unused
- again. Prior to Python 2.5, arenas (256KB chunks of memory) were never
- freed. Some applications will see a drop in virtual memory size now,
- especially long-running applications that, from time to time, temporarily
- use a large number of small objects. Note that when Python returns an
- arena to the platform C's ``free()``, there's no guarantee that the
- platform C library will in turn return that memory to the operating system.
- The effect of the patch is to stop making that impossible, and in tests it
- appears to be effective at least on Microsoft C and gcc-based systems.
- Thanks to Evan Jones for hard work and patience.
-
-- Patch #1434038: property() now uses the getter's docstring if there is
- no "doc" argument given. This makes it possible to legitimately use
- property() as a decorator to produce a read-only property.
-
-- PEP 357, patch 1436368: add an __index__ method to int/long and a matching
- nb_index slot to the PyNumberMethods struct. The slot is consulted instead
- of requiring an int or long in slicing and a few other contexts, enabling
- other objects (e.g. Numeric Python's integers) to be used as slice indices.
-
-- Fixed various bugs reported by Coverity's Prevent tool.
-
-- PEP 352, patch #1104669: Make exceptions new-style objects. Introduced the
- new exception base class, BaseException, which has a new message attribute.
- KeyboardInterrupt and SystemExit to directly inherit from BaseException now.
- Raising a string exception now raises a DeprecationWarning.
-
-- Patch #1438387, PEP 328: relative and absolute imports. Imports can now be
- explicitly relative, using 'from .module import name' to mean 'from the same
- package as this module is in. Imports without dots still default to the
- old relative-then-absolute, unless 'from __future__ import
- absolute_import' is used.
-
-- Properly check if 'warnings' raises an exception (usually when a filter set
- to "error" is triggered) when raising a warning for raising string
- exceptions.
-
-- CO_GENERATOR_ALLOWED is no longer defined. This behavior is the default.
- The name was removed from Include/code.h.
-
-- PEP 308: conditional expressions were added: (x if cond else y).
-
-- Patch 1433928:
- - The copy module now "copies" function objects (as atomic objects).
- - dict.__getitem__ now looks for a __missing__ hook before raising
- KeyError.
-
-- PEP 343: with statement implemented. Needs ``from __future__ import
- with_statement``. Use of 'with' as a variable will generate a warning.
- Use of 'as' as a variable will also generate a warning (unless it's
- part of an import statement).
- The following objects have __context__ methods:
- - The built-in file type.
- - The thread.LockType type.
- - The following types defined by the threading module:
- Lock, RLock, Condition, Semaphore, BoundedSemaphore.
- - The decimal.Context class.
-
-- Fix the encodings package codec search function to only search
- inside its own package. Fixes problem reported in patch #1433198.
-
- Note: Codec packages should implement and register their own
- codec search function. PEP 100 has the details.
-
-- PEP 353: Using ``Py_ssize_t`` as the index type.
-
-- ``PYMALLOC_DEBUG`` builds now add ``4*sizeof(size_t)`` bytes of debugging
- info to each allocated block, since the ``Py_ssize_t`` changes (PEP 353)
- now allow Python to make use of memory blocks exceeding 2**32 bytes for
- some purposes on 64-bit boxes. A ``PYMALLOC_DEBUG`` build was limited
- to 4-byte allocations before.
-
-- Patch #1400181, fix unicode string formatting to not use the locale.
- This is how string objects work. u'%f' could use , instead of .
- for the decimal point. Now both strings and unicode always use periods.
-
-- Bug #1244610, #1392915, fix build problem on OpenBSD 3.7 and 3.8.
- configure would break checking curses.h.
-
-- Bug #959576: The pwd module is now builtin. This allows Python to be
- built on UNIX platforms without $HOME set.
-
-- Bug #1072182, fix some potential problems if characters are signed.
-
-- Bug #889500, fix line number on SyntaxWarning for global declarations.
-
-- Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
-
-- Support for converting hex strings to floats no longer works.
- This was not portable. float('0x3') now raises a ValueError.
-
-- Patch #1382163: Expose Subversion revision number to Python. New C API
- function Py_GetBuildNumber(). New attribute sys.subversion. Build number
- is now displayed in interactive prompt banner.
-
-- Implementation of PEP 341 - Unification of try/except and try/finally.
- "except" clauses can now be written together with a "finally" clause in
- one try statement instead of two nested ones. Patch #1355913.
-
-- Bug #1379994: Builtin unicode_escape and raw_unicode_escape codec
- now encodes backslash correctly.
-
-- Patch #1350409: Work around signal handling bug in Visual Studio 2005.
-
-- Bug #1281408: Py_BuildValue now works correctly even with unsigned longs
- and long longs.
-
-- SF Bug #1350188, "setdlopenflags" leads to crash upon "import"
- It was possible for dlerror() to return a NULL pointer, so
- it will now use a default error message in this case.
-
-- Replaced most Unicode charmap codecs with new ones using the
- new Unicode translate string feature in the builtin charmap
- codec; the codecs were created from the mapping tables available
- at ftp.unicode.org and contain a few updates (e.g. the Mac OS
- encodings now include a mapping for the Apple logo)
-
-- Added a few more codecs for Mac OS encodings
-
-- Sped up some Unicode operations.
-
-- A new AST parser implementation was completed. The abstract
- syntax tree is available for read-only (non-compile) access
- to Python code; an _ast module was added.
-
-- SF bug #1167751: fix incorrect code being produced for generator expressions.
- The following code now raises a SyntaxError: foo(a = i for i in range(10))
-
-- SF Bug #976608: fix SystemError when mtime of an imported file is -1.
-
-- SF Bug #887946: fix segfault when redirecting stdin from a directory.
- Provide a warning when a directory is passed on the command line.
-
-- Fix segfault with invalid coding.
-
-- SF bug #772896: unknown encoding results in MemoryError.
-
-- All iterators now have a Boolean value of True. Formerly, some iterators
- supported a __len__() method which evaluated to False when the iterator
- was empty.
-
-- On 64-bit platforms, when __len__() returns a value that cannot be
- represented as a C int, raise OverflowError.
-
-- test__locale is skipped on OS X < 10.4 (only partial locale support is
- present).
-
-- SF bug #893549: parsing keyword arguments was broken with a few format
- codes.
-
-- Changes donated by Elemental Security to make it work on AIX 5.3
- with IBM's 64-bit compiler (SF patch #1284289). This also closes SF
- bug #105470: test_pwd fails on 64bit system (Opteron).
-
-- Changes donated by Elemental Security to make it work on HP-UX 11 on
- Itanium2 with HP's 64-bit compiler (SF patch #1225212).
-
-- Disallow keyword arguments for type constructors that don't use them
- (fixes bug #1119418).
-
-- Forward UnicodeDecodeError into SyntaxError for source encoding errors.
-
-- SF bug #900092: When tracing (e.g. for hotshot), restore 'return' events for
- exceptions that cause a function to exit.
-
-- The implementation of set() and frozenset() was revised to use its
- own internal data structure. Memory consumption is reduced by 1/3
- and there are modest speed-ups as well. The API is unchanged.
-
-- SF bug #1238681: freed pointer is used in longobject.c:long_pow().
-
-- SF bug #1229429: PyObject_CallMethod failed to decrement some
- reference counts in some error exit cases.
-
-- SF bug #1185883: Python's small-object memory allocator took over
- a block managed by the platform C library whenever a realloc specified
- a small new size. However, there's no portable way to know then how
- much of the address space following the pointer is valid, so there's no
- portable way to copy data from the C-managed block into Python's
- small-object space without risking a memory fault. Python's small-object
- realloc now leaves such blocks under the control of the platform C
- realloc.
-
-- SF bug #1232517: An overflow error was not detected properly when
- attempting to convert a large float to an int in os.utime().
-
-- SF bug #1224347: hex longs now print with lowercase letters just
- like their int counterparts.
-
-- SF bug #1163563: the original fix for bug #1010677 ("thread Module
- Breaks PyGILState_Ensure()") broke badly in the case of multiple
- interpreter states; back out that fix and do a better job (see
- http://mail.python.org/pipermail/python-dev/2005-June/054258.html
- for a longer write-up of the problem).
-
-- SF patch #1180995: marshal now uses a binary format by default when
- serializing floats.
-
-- SF patch #1181301: on platforms that appear to use IEEE 754 floats,
- the routines that promise to produce IEEE 754 binary representations
- of floats now simply copy bytes around.
-
-- bug #967182: disallow opening files with 'wU' or 'aU' as specified by PEP
- 278.
-
-- patch #1109424: int, long, float, complex, and unicode now check for the
- proper magic slot for type conversions when subclassed. Previously the
- magic slot was ignored during conversion. Semantics now match the way
- subclasses of str always behaved. int/long/float, conversion of an instance
- to the base class has been moved to the proper nb_* magic slot and out of
- PyNumber_*().
- Thanks Walter D�rwald.
-
-- Descriptors defined in C with a PyGetSetDef structure, where the setter is
- NULL, now raise an AttributeError when attempting to set or delete the
- attribute. Previously a TypeError was raised, but this was inconsistent
- with the equivalent pure-Python implementation.
-
-- It is now safe to call PyGILState_Release() before
- PyEval_InitThreads() (note that if there is reason to believe there
- are multiple threads around you still must call PyEval_InitThreads()
- before using the Python API; this fix is for extension modules that
- have no way of knowing if Python is multi-threaded yet).
-
-- Typing Ctrl-C whilst raw_input() was waiting in a build with threads
- disabled caused a crash.
-
-- Bug #1165306: instancemethod_new allowed the creation of a method
- with im_class == im_self == NULL, which caused a crash when called.
-
-- Move exception finalisation later in the shutdown process - this
- fixes the crash seen in bug #1165761
-
-- Added two new builtins, any() and all().
-
-- Defining a class with empty parentheses is now allowed
- (e.g., ``class C(): pass`` is no longer a syntax error).
- Patch #1176012 added support to the 'parser' module and 'compiler' package
- (thanks to logistix for that added support).
-
-- Patch #1115086: Support PY_LONGLONG in structmember.
-
-- Bug #1155938: new style classes did not check that __init__() was
- returning None.
-
-- Patch #802188: Report characters after line continuation character
- ('\') with a specific error message.
-
-- Bug #723201: Raise a TypeError for passing bad objects to 'L' format.
-
-- Bug #1124295: the __name__ attribute of file objects was
- inadvertently made inaccessible in restricted mode.
-
-- Bug #1074011: closing sys.std{out,err} now causes a flush() and
- an ferror() call.
-
-- min() and max() now support key= arguments with the same meaning as in
- list.sort().
-
-- The peephole optimizer now performs simple constant folding in expressions:
- (2+3) --> (5).
-
-- set and frozenset objects can now be marshalled. SF #1098985.
-
-- Bug #1077106: Poor argument checking could cause memory corruption
- in calls to os.read().
-
-- The parser did not complain about future statements in illegal
- positions. It once again reports a syntax error if a future
- statement occurs after anything other than a doc string.
-
-- Change the %s format specifier for str objects so that it returns a
- unicode instance if the argument is not an instance of basestring and
- calling __str__ on the argument returns a unicode instance.
-
-- Patch #1413181: changed ``PyThreadState_Delete()`` to forget about the
- current thread state when the auto-GIL-state machinery knows about
- it (since the thread state is being deleted, continuing to remember it
- can't help, but can hurt if another thread happens to get created with
- the same thread id).
-

-
-Library
--------
-
-- Patch #1388073: Numerous __-prefixed attributes of unittest.TestCase have
- been renamed to have only a single underscore prefix. This was done to
- make subclassing easier.
-
-- PEP 338: new module runpy defines a run_module function to support
- executing modules which provide access to source code or a code object
- via the PEP 302 import mechanisms.
-
-- The email module's parsedate_tz function now sets the daylight savings
- flag to -1 (unknown) since it can't tell from the date whether it should
- be set.
-
-- Patch #624325: urlparse.urlparse() and urlparse.urlsplit() results
- now sport attributes that provide access to the parts of the result.
-
-- Patch #1462498: sgmllib now handles entity and character references
- in attribute values.
-
-- Added the sqlite3 package. This is based on pysqlite2.1.3, and provides
- a DB-API interface in the standard library. You'll need sqlite 3.0.8 or
- later to build this - if you have an earlier version, the C extension
- module will not be built.
-
-- Bug #1460340: ``random.sample(dict)`` failed in various ways. Dicts
- aren't officially supported here, and trying to use them will probably
- raise an exception some day. But dicts have been allowed, and "mostly
- worked", so support for them won't go away without warning.
-
-- Bug #1445068: getpass.getpass() can now be given an explicit stream
- argument to specify where to write the prompt.
-
-- Patch #1462313, bug #1443328: the pickle modules now can handle classes
- that have __private names in their __slots__.
-
-- Bug #1250170: mimetools now handles socket.gethostname() failures gracefully.
-
-- patch #1457316: "setup.py upload" now supports --identity to select the
- key to be used for signing the uploaded code.
-
-- Queue.Queue objects now support .task_done() and .join() methods
- to make it easier to monitor when daemon threads have completed
- processing all enqueued tasks. Patch #1455676.
-
-- popen2.Popen objects now preserve the command in a .cmd attribute.
-
-- Added the ctypes ffi package.
-
-- email 4.0 package now integrated. This is largely the same as the email 3.0
- package that was included in Python 2.3, except that PEP 8 module names are
- now used (e.g. mail.message instead of email.Message). The MIME classes
- have been moved to a subpackage (e.g. email.mime.text instead of
- email.MIMEText). The old names are still supported for now. Several
- deprecated Message methods have been removed and lots of bugs have been
- fixed. More details can be found in the email package documentation.
-
-- Patches #1436130/#1443155: codecs.lookup() now returns a CodecInfo object
- (a subclass of tuple) that provides incremental decoders and encoders
- (a way to use stateful codecs without the stream API). Python functions
- codecs.getincrementaldecoder() and codecs.getincrementalencoder() as well
- as C functions PyCodec_IncrementalEncoder() and PyCodec_IncrementalDecoder()
- have been added.
-
-- Patch #1359365: Calling next() on a closed StringIO.String object raises
- a ValueError instead of a StopIteration now (like file and cString.String do).
- cStringIO.StringIO.isatty() will raise a ValueError now if close() has been
- called before (like file and StringIO.StringIO do).
-
-- A regrtest option -w was added to re-run failed tests in verbose mode.
-
-- Patch #1446372: quit and exit can now be called from the interactive
- interpreter to exit.
-
-- The function get_count() has been added to the gc module, and gc.collect()
- grew an optional 'generation' argument.
-
-- A library msilib to generate Windows Installer files, and a distutils
- command bdist_msi have been added.
-
-- PEP 343: new module contextlib.py defines decorator @contextmanager
- and helpful context managers nested() and closing().
-
-- The compiler package now supports future imports after the module docstring.
-
-- Bug #1413790: zipfile now sanitizes absolute archive names that are
- not allowed by the specs.
-
-- Patch #1215184: FileInput now can be given an opening hook which can
- be used to control how files are opened.
-
-- Patch #1212287: fileinput.input() now has a mode parameter for
- specifying the file mode input files should be opened with.
-
-- Patch #1215184: fileinput now has a fileno() function for getting the
- current file number.
-
-- Patch #1349274: gettext.install() now optionally installs additional
- translation functions other than _() in the builtin namespace.
-
-- Patch #1337756: fileinput now accepts Unicode filenames.
-
-- Patch #1373643: The chunk module can now read chunks larger than
- two gigabytes.

- in pydoc.
-
-- Patch #1412872: zipfile now sets the creator system to 3 (Unix)
- unless the system is Win32.
-
-- Patch #1349118: urllib now supports user:pass@ style proxy
- specifications, raises IOErrors when proxies for unsupported protocols
- are defined, and uses the https proxy on https redirections.
-
-- Bug #902075: urllib2 now supports 'host:port' style proxy specifications.
-
-- Bug #1407902: Add support for sftp:// URIs to urlparse.
-
-- Bug #1371247: Update Windows locale identifiers in locale.py.
-
-- Bug #1394565: SimpleHTTPServer now doesn't choke on query parameters
- any more.
-
-- Bug #1403410: The warnings module now doesn't get confused
- when it can't find out the module name it generates a warning for.
-
-- Patch #1177307: Added a new codec utf_8_sig for UTF-8 with a BOM signature.
-
-- Patch #1157027: cookielib mishandles RFC 2109 cookies in Netscape mode
-
-- Patch #1117398: cookielib.LWPCookieJar and .MozillaCookieJar now raise
- LoadError as documented, instead of IOError. For compatibility,
- LoadError subclasses IOError.
-
-- Added the hashlib module. It provides secure hash functions for MD5 and
- SHA1, 224, 256, 384, and 512. Note that recent developments make the
- historic MD5 and SHA1 unsuitable for cryptographic-strength applications.
- In <http://mail.python.org/pipermail/python-dev/2005-December/058850.html>
- Ronald L. Rivest offered this advice for Python:
-
- "The consensus of researchers in this area (at least as
- expressed at the NIST Hash Function Workshop 10/31/05),
- is that SHA-256 is a good choice for the time being, but
- that research should continue, and other alternatives may

-- Enhancements to the csv module:
-
- + Dialects are now validated by the underlying C code, better
- reflecting its capabilities, and improving its compliance with
- PEP 305.
- + Dialect parameter parsing has been re-implemented to improve error
- reporting.
- + quotechar=None and quoting=QUOTE_NONE now work the way PEP 305
- dictates.
- + the parser now removes the escapechar prefix from escaped characters.
- + when quoting=QUOTE_NONNUMERIC, the writer now tests for numeric
- types, rather than any object that can be represented as a numeric.
- + when quoting=QUOTE_NONNUMERIC, the reader now casts unquoted fields
- to floats.
- + reader now allows \r characters to be quoted (previously it only allowed
- \n to be quoted).
- + writer doublequote handling improved.
- + Dialect classes passed to the module are no longer instantiated by
- the module before being parsed (the former validation scheme required
- this, but the mechanism was unreliable).
- + The dialect registry now contains instances of the internal
- C-coded dialect type, rather than references to python objects.
- + the internal c-coded dialect type is now immutable.
- + register_dialect now accepts the same keyword dialect specifications
- as the reader and writer, allowing the user to register dialects
- without first creating a dialect class.
- + a configurable limit to the size of parsed fields has been added -
- previously, an unmatched quote character could result in the entire
- file being read into the field buffer before an error was reported.
- + A new module method csv.field_size_limit() has been added that sets
- the parser field size limit (returning the former limit). The initial
- limit is 128kB.
- + A line_num attribute has been added to the reader object, which tracks
- the number of lines read from the source iterator. This is not
- the same as the number of records returned, as records can span
- multiple lines.
- + reader and writer objects were not being registered with the cyclic-GC.
- This has been fixed.
-
-- _DummyThread objects in the threading module now delete self.__block that is
- inherited from _Thread since it uses up a lock allocated by 'thread'. The
- lock primitives tend to be limited in number and thus should not be wasted on
- a _DummyThread object. Fixes bug #1089632.
-
-- The imghdr module now detects Exif files.
-
-- StringIO.truncate() now correctly adjusts the size attribute.
- (Bug #951915).
-
-- locale.py now uses an updated locale alias table (built using
- Tools/i18n/makelocalealias.py, a tool to parse the X11 locale
- alias file); the encoding lookup was enhanced to use Python's
- encoding alias table.
-
-- moved deprecated modules to Lib/lib-old: whrandom, tzparse, statcache.
-
-- the pickle module no longer accepts the deprecated None option in the
- args tuple returned by __reduce__().
-
-- optparse now optionally imports gettext. This allows its use in setup.py.
-
-- the pickle module no longer uses the deprecated bin parameter.
-
-- the shelve module no longer uses the deprecated binary parameter.
-
-- the pstats module no longer uses the deprecated ignore() method.
-
-- the filecmp module no longer uses the deprecated use_statcache argument.
-
-- unittest.TestCase.run() and unittest.TestSuite.run() can now be successfully
- extended or overridden by subclasses. Formerly, the subclassed method would
- be ignored by the rest of the module. (Bug #1078905).
-
-- heapq.nsmallest() and heapq.nlargest() now support key= arguments with
- the same meaning as in list.sort().
-
-- Bug #1076985: ``codecs.StreamReader.readline()`` now calls ``read()`` only
- once when a size argument is given. This prevents a buffer overflow in the
- tokenizer with very long source lines.
-
-- Bug #1083110: ``zlib.decompress.flush()`` would segfault if called
- immediately after creating the object, without any intervening
- ``.decompress()`` calls.
-
-- The reconvert.quote function can now emit triple-quoted strings. The
- reconvert module now has some simple documentation.
-
-- ``UserString.MutableString`` now supports negative indices in
- ``__setitem__`` and ``__delitem__``
-
-- Bug #1149508: ``textwrap`` now handles hyphenated numbers (eg. "2004-03-05")
- correctly.
-
-- Partial fixes for SF bugs #1163244 and #1175396: If a chunk read by
- ``codecs.StreamReader.readline()`` has a trailing "\r", read one more
- character even if the user has passed a size parameter to get a proper
- line ending. Remove the special handling of a "\r\n" that has been split
- between two lines.
-
-- Bug #1251300: On UCS-4 builds the "unicode-internal" codec will now complain
- about illegal code points. The codec now supports PEP 293 style error
- handlers.
-
-- Bug #1235646: ``codecs.StreamRecoder.next()`` now reencodes the data it reads
- from the input stream, so that the output is a byte string in the correct
- encoding instead of a unicode string.
-
-- Bug #1202493: Fixing SRE parser to handle '{}' as perl does, rather than
- considering it exactly like a '*'.
-
-- Bug #1245379: Add "unicode-1-1-utf-7" as an alias for "utf-7" to
- ``encodings.aliases``.
-
-- ` uu.encode()`` and ``uu.decode()`` now support unicode filenames.
-
-- Patch #1413711: Certain patterns of differences were making difflib
- touch the recursion limit.
-
-- Bug #947906: An object oriented interface has been added to the calendar
- module. It's possible to generate HTML calendar now and the module can be
- called as a script (e.g. via ``python -mcalendar``). Localized month and
- weekday names can be ouput (even if an exotic encoding is used) using
- special classes that use unicode.
-
-Build
------
-
-- Fix test_float, test_long, and test_struct failures on Tru64 with gcc
- by using -mieee gcc option.
-
-- Patch #1432345: Make python compile on DragonFly.
-
-- Build support for Win64-AMD64 was added.
-
-- Patch #1428494: Prefer linking against ncursesw over ncurses library.
-
-- Patch #881820: look for openpty and forkpty also in libbsd.
-
-- The sources of zlib are now part of the Python distribution (zlib 1.2.3).
- The zlib module is now builtin on Windows.
-
-- Use -xcode=pic32 for CCSHARED on Solaris with SunPro.
-
-- Bug #1189330: configure did not correctly determine the necessary
- value of LINKCC if python was built with GCC 4.0.
-
-- Upgrade Windows build to zlib 1.2.3 which eliminates a potential security
- vulnerability in zlib 1.2.1 and 1.2.2.
-
-- EXTRA_CFLAGS has been introduced as an environment variable to hold compiler
- flags that change binary compatibility. Changes were also made to
- distutils.sysconfig to also use the environment variable when used during
- compilation of the interpreter and of C extensions through distutils.
-
-- SF patch 1171735: Darwin 8's headers are anal about POSIX compliance,
- and linking has changed (prebinding is now deprecated, and libcc_dynamic
- no longer exists). This configure patch makes things right.
-
-- Bug #1158607: Build with --disable-unicode again.
-
-- spwdmodule.c is built only if either HAVE_GETSPNAM or HAVE_HAVE_GETSPENT is
- defined. Discovered as a result of not being able to build on OS X.
-
-- setup.py now uses the directories specified in LDFLAGS using the -L option
- and in CPPFLAGS using the -I option for adding library and include
- directories, respectively, for compiling extension modules against. This has
- led to the core being compiled using the values in CPPFLAGS. It also removes
- the need for the special-casing of both DarwinPorts and Fink for darwin since
- the proper directories can be specified in LDFLAGS (``-L/sw/lib`` for Fink,
- ``-L/opt/local/lib`` for DarwinPorts) and CPPFLAGS (``-I/sw/include`` for
- Fink, ``-I/opt/local/include`` for DarwinPorts).
-
-- Test in configure.in that checks for tzset no longer dependent on tm->tm_zone
- to exist in the struct (not required by either ISO C nor the UNIX 2 spec).
- Tests for sanity in tzname when HAVE_TZNAME defined were also defined.
- Closes bug #1096244. Thanks Gregory Bond.
-
-C API
------
-
-- ``PyMem_{Del, DEL}`` and ``PyMem_{Free, FREE}`` no longer map to
- ``PyObject_{Free, FREE}``. They map to the system ``free()`` now. If memory
- is obtained via the ``PyObject_`` family, it must be released via the
- ``PyObject_`` family, and likewise for the ``PyMem_`` family. This has
- always been officially true, but when Python's small-object allocator was
- introduced, an attempt was made to cater to a few extension modules
- discovered at the time that obtained memory via ``PyObject_New`` but
- released it via ``PyMem_DEL``. It's years later, and if such code still
- exists it will fail now (probably with segfaults, but calling wrong
- low-level memory management functions can yield many symptoms).
-
-- Added a C API for set and frozenset objects.
-
-- Removed PyRange_New().
-
-- Patch #1313939: PyUnicode_DecodeCharmap() accepts a unicode string as the
- mapping argument now. This string is used as a mapping table. Byte values
- greater than the length of the string and 0xFFFE are treated as undefined
- mappings.
-
-
-Tests
------
-
-- In test_os, st_?time is now truncated before comparing it with ST_?TIME.
-
-- Patch #1276356: New resource "urlfetch" is implemented. This enables
- even impatient people to run tests that require remote files.
-
-

-
-- FreeBSD 7 support is added.
-
-
-Tools/Demos

-
-- Added two new files to Tools/scripts: pysource.py, which recursively
- finds Python source files, and findnocoding.py, which finds Python
- source files that need an encoding declaration.
- Patch #784089, credits to Oleg Broytmann.
-
-- Bug #1072853: pindent.py used an uninitialized variable.
