Actually, I think this is fixed already by #250 here:
I tested a pretty much identical change, which held up while manually deleting the sofile directory and (not that a difference should be expected) triggering systemctl start systemd-tmpfiles-clean
with a short cleanup time.
from callr.
That typically happens if some cleaner process cleans up the temporary directory. I forgot how this works exactly, but we can probably make it more robust, still.
from callr.
This is occurring fairly frequently for me -- is there an option to change the temporary directory used by callr in order to mitigate this issue?
from callr.
Yes, see ?tmpdir
.
from callr.
Thanks; I was hoping to restrict the change to callr itself but I will try this if need be. I am, though, uncertain that a cleaner process could be responsible for this error. On this system the /tmp directory is cleaned every 10 days, and was last cleaned 5 days ago. The issue has occurred multiple times and occurs at most some seconds after the background sessions is launched. Could it be a race condition of some kind involving prepare_client_libs? This error occurs when using r_bg
, and not r_session
.
from callr.
Oh, I understand now -- the client files are prepared during the start of an R session and are subsequently reused, and so for an R session that has been open for > 10 days the client sofile can be pulled out from under the session's feet -- is this correct?
from callr.
Yes, that's correct.
I'll try to improve this, but for now using another directory could be a workaround.
from callr.
OK, so if I understand correctly, this is now fixed.
