Wait for > subtle unreproducible race conditions to manifest? one solution could be do have an API function that must have been called from the rakefile to allow concurrent execution of Tasks. If that function wasn't called, -j defaults to 1 (is ignored). This has the drawback that a rakefile has to explicitly enable parallel execution but on the other side, thread unsafe rakefile won't executed in parallel. Example: rakefile: enable_parallel task :one do #compile file one end task :two do #compile file two end task :all => [:one, :two] do #link file one and two end running rake with -j 2 could execute task :one and :two in parallel. Without the call to enable_parallel(), -j would effectively ignored. kind regards Torsten _______________________________________________ Rake-devel mailing list [email protected] http://rubyforge.org/mailman/listinfo/rake-devel
