In general the alpha looks very good. There seems to be no new
critical gcc warnings, interactive testing with builtin grep looks OK
(e.g. we tested job control and repeated CTRL-C usage for grep -r
etc.) and Solaris uses |posix_spawn()| without problems.
The only issue we stumbled over is ./src/lib/libcmd/iconv.c, function
|listall()|:
-- snip --
if (!access(p, X_OK) || !access(p += 4, X_OK))
{
sfprintf(sfstdout, "\n");
execl(p, "iconv", "-l", 0);
}
-- snip --
... obviously the |execl()| will terminate the whole shell... any
suggestions what can be used in this case (|sh_run()| _may_ trigger a
recursive loop if ".sh.op_astbin=/bin" is used... right ?) ?
The only other (now annoying... since it was AFAIK reported multiple
times) is that "shtests" should really really set "ulimit -n" to
something higher than 256 on older Unix variants... it's generating
false errors since some tests rely on "ulimit -n 512' while old Unix
variants like Solaris sometimes still default to 256 (and "ulimit -s"
should be at least 65536 to handle deeper stack consumption on RISC
architectures (e.g. Solaris/SPARC and Linux/IA64)).
The following patch solves that:
