Hello,
I am experiencing strange errors related to code that tries to ensure a
directory is there:
dir = dirname(dest)
if isfile(dir)
warn("Directory is file: ", dir)
continue
else
mkpath(dir)
end
However, while running this script parallel on a cluster, I regularly get
the error:
ERROR: LoadError: SystemError: mkdir: File exists
in mkdir at file.jl:42
in mkpath at file.jl:50
[inlined code] from /home/...
Maybe it is NFS that is caching too aggressively, or lying about the
existence of concurrently created directories. I don't know.
Would there be a way to make `mkpath()` behave more atomically? At the
moment I have to replace the `mkpath()` above with `ensuredir()` below:
function ensuredir(d::AbstractString)
if !isdir(d)
try
mkpath(d)
catch e
isdir(d) || throw(e)
end
end
end
Thanks,
---david
P.S. (If this is a re-post, I didn't loose the original in the end in
google somewhat buggy groups interface...)
