Hello,
We have some problems with read command on latest busybox
version.
$ read -n 5
123456
This command isn't returning after the fifth character. It seems
that it is blocked in the poll call. Only after the 6th character
is entered, the poll returns.
poll([{fd=0, events=POLLIN}], 1, -1) = 1 ([{fd=0, revents=POLLIN}])
read(0, "1", 1) = 1
poll([{fd=0, events=POLLIN}], 1, -1) = 1 ([{fd=0, revents=POLLIN}])
read(0, "2", 1) = 1
poll([{fd=0, events=POLLIN}], 1, -1
This is very likely to be caused by the latest patches:
* hush: use SA_RESTARTed signal handlers across read. (10c0131a)
* hush: make read builtin interruptible. (80542bad)
thanks,
Daniel.
