Ref #310 #13954 #50718
I just got bitten by this (again), and it was very confusing (again): I converted my interactive job to a slurm job and thought it didn't work properly when I didn't see any debug output in the log file.
@KristofferC you say in #50718 that that PR would flush too much, and I agree this is potentially true for arbitrary IO, but here I propose to just flush on println(x), which is presumably not used for "serious" IO. This would not impact
println(io, x)
. It has the downside thatprintln(x)
is not the same asprintln(stdout, x)
but I think that's fair game compared to the confusion caused by not buffering anything.
