Solve the following python programming problem given the following code:
def _install_component(self, component, destdir, release = True) : 
    installed_files = list () 
    manifest_name = ('install_manifest_%s.txt' % component) 
    if ((not release) and sys.platform.startswith ('win')) : 
        manifest_name = ('install_manifest_%s_debug.txt' % component) 
manifest_path = os.path.join (self.path, manifest_name) 
    if (not os.path.exists (manifest_path)) : 
        if (component == 'test') : 
            return list () 
mask = self._read_install_mask (component) 
        if release : 
            mask.extend (self._read_install_mask ('release')) 
if ((not src) and (component == 'runtime')) : 
            def filter_fun(x) : 
                return (qisys.sh.is_runtime (x) and (x != 'package.xml')) 
return qisys.sh.install (self.path, destdir, filter_fun = filter_fun) 
else : 
            mask.append ('exclude .*\\.mask') 
            mask.append ('exclude package\\.xml') 
            return self._install_with_mask (destdir, mask) 
else : 
        with open (manifest_path, 'r') as fp : 
            lines = fp.readlines () 
            for line in lines : 
                line = line.strip ()
