Not sure if this is a bug, so posting here first. If I run:
cnt <- 0L
while (TRUE) {
cnt <- cnt + 1L
p <- pipe("echo /dev/stdin > /dev/null", open = "w")
writeLines("foobar", p)
tryCatch(close(p), error = function(e) { print(cnt); stop(e)})
}
then once cnt gets to around 650, it fails with:
[1] 654
Error in close.connection(p) : ignoring SIGPIPE signal
Should I not be using pipe() in this way? Here is my sessionInfo()
