If I observe a directory for changes but send a signal to interrupt the script before any changes happen I got an unhandled error message. This is not the case using the code in the REPL or if there was a change in directory before.
So what I’m doing wrong here? Thx for answers and hints as always.
Here are the code lines (sorry I dont see how to format the code lines nicely):
#handle interruption - not needed in REPL
ccall(:jl_exit_on_sigint, Void, (Cint,), 0)
#directory to observe
dir = “/path_to_dir/”
try w = watch_file(dir,-1) if w.changed println("changed") end catch x return error("Recieved interupting signal while watching $dir") end
How I said, if any change happens before the interrupting signal comes all works fine.
Otherwise I got this error:
ERROR (unhandled task failure): InterruptException:
 process_events at ./libuv.jl:82 [inlined]
 wait() at ./event.jl:216
 wait(::Condition) at ./event.jl:27
 macro expansion at ./distributed/remotecall.jl:230 [inlined]
 (::Base.Distributed.##131#132)() at ./event.jl:73
and the script is still running.
