This configuration is for timing how we handle the NxM interaction when
we build a lot of targets from a lot of source files.
We create a list of 100 target files that will each be built by copying
a file from a corresponding list of 100 source files. The source
files themselves are each built by a Python function action that's the
equivalent of "echo contents > $TARGET".
"""
target_cnt = 100
env = Environment()
def create_file( env, target, source ):
t = str(target[0])
open( t, 'w' ).write('contents\n')
source_list = map(lambda t: 'source_%03d' % t, xrange(target_cnt))
target_list = map(lambda t: 'target_%03d' % t, xrange(target_cnt))
for source in source_list:
env.Command( source, [], create_file )
def copy_files( env, target, source ):
for t, s in zip(target, source):
open(str(t), 'w').write(open(str(s), 'r').read())
env.Command( target_list, source_list, copy_files )
