https://bugzilla.mcs.anl.gov/swift/show_bug.cgi?id=1369 Summary: NPE with filesys_mapper Product: Swift Version: 0.96 Platform: PC OS/Version: Linux Status: NEW Severity: normal Priority: P2 Component: General AssignedTo: [email protected] ReportedBy: [email protected] The following piece of code fails with a NullPointerException, when the file arrays out and err are using filesys_mapper. Changing the mapper to simple_mapper, gets the code running without issues. type file; int loops = toInt(arg("loops","50")); int delay = toInt(arg("delay", "1")); app (file out, file err) app_foo (file script, int delay) { bash @script delay stdout=@out stderr=@err; } file out[] <filesys_mapper; location="output", prefix="std", suffix=".out">; file err[] <filesys_mapper; location="output", prefix="std", suffix=".err">; //file out[] <simple_mapper; location="output", prefix="foo.", suffix=".out">; //file err[] <simple_mapper; location="output", prefix="foo.", suffix=".err">; file wrapper <"wrapper.sh">; foreach i in [1:loops] { tracef("Count : %i \n", i); (out[i], err[i]) = app_foo (wrapper, delay); } The logs from the run are here : http://users.rcc.uchicago.edu/~yadunand/filesys_mapper_NPE/ -- Configure bugmail: https://bugzilla.mcs.anl.gov/swift/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are watching all bug changes.
