2023-07-10ash: disable sleep as builtin, closes 15619Denys Vlasenko
Has a few annoying problems: * sleepcmd() -> sleep_main(), the parsing of bad arguments exits the shell. * sleep_for_duration() in sleep_main() has to be interruptible for ^C traps to work, which may be a problem for other users of sleep_for_duration(). * BUT, if sleep_for_duration() is interruptible, then SIGCHLD interrupts it as well (try "/bin/sleep 1 & sleep 10"). * sleep_main() must not allocate anything as ^C in ash longjmp's. (currently, allocations are only on error paths, in message printing). Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

This fixes arith-precedence1.tests. This breaks arith-ternary2.tests again (we now evaluate variables on not-taken branches). We need a better logic here anyway: not only bare variables should not evaluate when not-taken: 1 ? eval_me : do_not_eval but any (arbitrarily complex) expressions shouldn't evaluate as well! 1 ? var_is_set=1 : ((var_is_not_set=2,var2*=4)) function old new delta evaluate_string 1097 1148 +51 Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
