Log message:
Fix a possibly long-standing issue, but also possibly fallout from the db4
changes.  The "dbm" module could fail to build correctly, erroring out \ 
with:

*** WARNING: renaming "dbm" since importing it failed: \ 
build/lib.linux-i686-2.5/dbm.so: undefined symbol: dbm_firstkey

In this case, the "dbm" module has accidentally linked with \ 
"databases/gdbm",
which happens to be installed, but was never buildlinked in.  It may be
relevant that /usr/include/gdbm/ndbm.h is installed on this system.

Remove the "gdbm" test from the "dbm" module configuration, \ 
leaving the "ndbm"
support, and the fall-back "bdb" support (which will likely fall back \ 
to db4).

Bump PKGREVISION - the package would still install, but with missing
functionality.

Log message:
bump PKGREVs for Python pkgs, as suggested by David Sainty -- at least
on Linux one can't build some extensions against an old Python (with
spurious -ldb4 linkage) anymore
also sync the bl3 files of the non-default versions with python25
for consistency

Log message:
don't propagate the "cups" dependency, this is nut referenced by
the exported libraries
(according to the CVS log, this was only to work around spurious db4
dependencies which are hopefully fixed by my last change to db4/bl3)

Log message:
gdbm is in disabled_module_list, yet if it's found on the system
the module gets built anyway. Don't do that.

Log message:
Remove empty PLIST.common_end.

Log message:
Remove @dirrm entries from PLISTs

Log message:
Recursive ABI depends update and PKGREVISION bump for readline-6.0 shlib

What's New in Python 2.5.3c1?
=============================

*Release date: 13-Dec-2008*

Core and builtins
-----------------

- Issue #1706039: Support continued reading from a file even after
  EOF was hit.

- Issue #1683: prevent forking from interfering in threading storage.

- Issue #4597: Fixed several opcodes that weren't always propagating
  exceptions.

- Issue #4589: Propagated an exception thrown by a context manager's
  __exit__ method's result while it's being converted to bool.

- Issue #4317: Fixed a crash in the imageop.rgb2rgb8() function.

- Issue #4230: If ``__getattr__`` is a descriptor, it now functions correctly.

- Issue #4048: The parser module now correctly validates relative imports.

- Issue #4176: Fixed a crash when pickling an object which ``__reduce__``
  method does not return iterators for the 4th and 5th items.

- Issue #3967: Fixed a crash in the count() and find() methods of string-like
  objects, when the "start" parameter is a huge value.

- Issue #3936: The parser warnings for using "as" and "with" \ 
as variable names
  didn't fire after import statements.

- Issue #3751: str.rpartition would perform a left-partition when called with
  a unicode argument.

- Issue #3537: Fix an assertion failure when an empty but presized dict
  object was stored in the freelist.

- Apply security patches from Apple.

- Issue #2620: Overflow checking when allocating or reallocating memory
  was not always being done properly in some python types and extension
  modules.  PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
  all been updated to perform better checks and places in the code that
  would previously leak memory on the error path when such an allocation
  failed have been fixed.

- Issue #2242: Fix a crash when decoding invalid utf-7 input on certain
  Windows / Visual Studio versions.

- Issue #3360: Fix incorrect parsing of '020000000000.0', which
  produced a ValueError instead of giving the correct float.

- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
  set to a custom object whose write() method happens to install
  another file in sys.stdout.

- Issue #3088: Corrected a race condition in classes derived from
  threading.local: the first member set by a thread could be saved in
  another thread's dictionary.

- Issue #3100: Corrected a crash on deallocation of a subclassed weakref which
  holds the last (strong) reference to its referent.

- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
  having a self-referential tuple, which is possible from C code.  Nor did
  object's tp_str consider that a type's tp_str could do something that could
  lead to an inifinite recursion.  Py_ReprEnter() and Py_EnterRecursiveCall(),
  respectively, fixed the issues.  (Backport of r58288 from trunk.)

- Patch #1442: properly report exceptions when the PYTHONSTARTUP file
  cannot be executed.

- The compilation of a class nested in another class used to leak one
  reference on the outer class name.

- Issue #1477: With narrow Unicode builds, the unicode escape sequence
  \Uxxxxxxxx did not accept values outside the Basic Multilingual Plane.  This
  affected raw unicode literals and the 'raw-unicode-escape' codec.  Now
  UTF-16 surrogates are generated in this case, like normal unicode literals
  and the 'unicode-escape' codec.

- Issue #2321: use pymalloc for unicode object string data to reduce
  memory usage in some circumstances.

- Issue #2238: Some syntax errors in *args and **kwargs expressions could give
  bogus error messages.

- Issue #2587: In the C API, PyString_FromStringAndSize() takes a signed size
  parameter but was not verifying that it was greater than zero.  Values
  less than zero will now raise a SystemError and return NULL to indicate a
  bug in the calling C code.

- Issue #2588, #2589: Fix potential integer underflow and overflow
  conditions in the PyOS_vsnprintf C API function.

- Issue #1204: The configure script now tests for additional libraries
  that may be required when linking against readline.  This fixes issues
  with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).

- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
  library targets in the Makefile.

Library
-------

- Issue #3767: Convert Tk object to string in tkColorChooser.

- Issue #4342: Always convert Text.index result to string.

- Issue 3248: Allow placing ScrolledText in a PanedWindow.

- Issue #4084: Fix max, min, max_mag and min_mag Decimal methods to
  give correct results in the case where one argument is a quiet NaN
  and the other is a finite number that requires rounding.

- Issue #1776581 and #4302. Minor corrections to smtplib.

- Issue #3774: Fixed an error when create a Tkinter menu item without command
  and then remove it.

- Assigning methods to ctypes.Structure and ctypes.Union subclasses
  after creation of the class does now work correctly.  See Issue #1700288.

- Issue #3895: _lsprof could be crashed with an external timer that did not
  return a float when a Profiler object is garbage collected.

- Issues #3968 and #3969: two minor turtle problems.

- Issue #3547: Fixed ctypes structures bitfields of varying integer
  sizes.

- Issue #3762: platform.architecture() fails if python is lanched via
  its symbolic link.

- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
  api functions without holding the GIL, which could lead to a fatal
  error when they failed.

- Issue #2234: distutils failed for some versions of the cygwin compiler. The
  version reported by these tools does not necessarily follow the python
  version numbering scheme, so the module is less strict when parsing it.

- Issue #2222: Fixed reference leak when occured os.rename()
  fails unicode conversion on 2nd parameter. (windows only)

- Issue #3134: shutil referenced undefined WindowsError symbol.

- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
  menu entries were not deleted.

- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

- Issue #3339: dummy_thread.acquire() could return None which is not a valid
  return value.

- Issue #3116 and #1792:  Fix quadratic behavior in marshal.dumps().

- Issue #2682: ctypes callback functions no longer contain a cyclic
  reference to themselves.

- Issue #2670:  Fix a failure in urllib2.build_opener(), when passed two
  handlers that derive the same default base class.

- Issue #2495: tokenize.untokenize now inserts a space between two consecutive
  string literals; previously, ["" ""] was rendered as \ 
[""""], which is
  incorrect python code.

- Issue #2482: Make sure that the coefficient of a Decimal is always
  stored as a str instance, not as a unicode instance.  This ensures
  that str(Decimal) is always an instance of str.  This fixes a
  regression from Python 2.5.1 to Python 2.5.2.

- Issue #2478: fix failure of decimal.Decimal(0).sqrt()

- Issue #2432: give DictReader the dialect and line_num attributes
  advertised in the docs.

- Issue #1747858: Fix chown to work with large uid's and gid's on 64-bit
  platforms.

- Bug #2220: handle rlcompleter attribute match failure more gracefully.

- Bug #1725737: In distutil's sdist, exclude RCS, CVS etc. also in the
  root directory, and also exclude .hg, .git, .bzr, and _darcs.

- Bug #1389051: imaplib causes excessive memory fragmentation when reading
  large messages.

- Bug #1389051, 1092502: fix excessively large memory allocations when
  calling .read() on a socket object wrapped with makefile().

- Bug #1433694: minidom's .normalize() failed to set .nextSibling for
  last child element.

- Issue #2791: subprocess.Popen.communicate explicitly closes its
  stdout and stderr fds rather than leaving them open until the
  instance is destroyed.

- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
  in the common case when the data is returned from the underlying socket
  in increments much smaller than bignumber.

- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
  argument in python 2.5, this broke code that subclassed Popen to include its
  own poll method.  Fixed my moving _deadstate to an _internal_poll method.

- Issue #2113: Fix error in subprocess.Popen if the select system call is
  interrupted by a signal.

- Issue #874900: after an os.fork() call the threading module state is cleaned
  up in the child process to prevent deadlock and report proper thread counts
  if the new process uses the threading module.

- Issue #3309: Fix bz2.BZFile iterator to release its internal lock
  properly when raising an exception due to the bz2file being closed.
  Prevents a deadlock.

Build
-----

- Issue #4368: Don't define _XOPEN_SOURCE on FreeBSD 4.*.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.
