	    Thiago Jung Bauermann  <bauerman@br.ibm.com>
   	    Tom Tromey  <tromey@redhat.com>

	* breakpoint.c (condition_command): Simplify.  Move condition
	setting code to ...
	(set_breakpoint_condition): ... here.  New function.
	* breakpoint.h  (set_breakpoint_condition): Declare.
	* Makefile.in (SUBDIR_PYTHON_OBS): Add py-breakpoint.
	(SUBDIR_PYTHON_SRCS): Likewise.
	(py-breakpoint.o): New rule.
	* python/py-breakpoint.c: New file.
	* python/python-internal.h (gdbpy_breakpoints)
	(gdbpy_initialize_breakpoints): Declare.
	(GDB_PY_SET_HANDLE_EXCEPTION) Define.


2010-04-09  Phil Muldoon  <pmuldoon@redhat.com>

	* gdb.python/py-breakpoint.exp: New File.
	* gdb.python/py-breakpoint.C: Ditto.
