Add filter() function to builtins #59

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Python 2.6 includes the function {{{filter()}}} in its set of builtins.  It 
would be advantageous to add this function to the VM's builtins.

Suggested implementation:

def filter(f, s):
    return [x for x in s if f(x)]

Discovered a bug along the way: if f is not a function, CALL_FUNCTION fails due 
to a 
PM_RET_ASSERT_FAIL.  The proper failure would be to throw a TypeError.  Code 
changed to 
make this happen.

Added system test t259.  Running system test reveals that RAM is low, created 
Issue #63 
to resolve low RAM.

After resolving issue #63, system tests pass.  Filter works on ipm, too.  Also, 
two t259 cases that throw TypeError on purpose did so.

Mainlined directly, see r408
