Various bits of what is known about busybox shells, in no particular order.

hush: fixed non-backgrounding of "sleep 1 &" and totally broken
|
|
|
|
|
"sleep 1 | sleep 2 &". Noticed a bug where successive jobs
|
|
|
|
|
get numbers 1,2,3 even when job #1 has exited before job# 2 is started.
|
|
|
|
|
(bash reuses #1 in this case)

hush: "sleep 1 | exit 3; echo $?" prints 0 because $? is substituted
|
|
|
|
|
_before_ pipe gets executed!! run_list_real() already has "pipe;echo"
|
|
|
|
|
parsed and handed to it for execution, so it sees "pipe"; "echo 0".

hush: removed setsid() and made job control sort-of-sometimes-work.
|
|
|
|
|
Ctrl-C in "rm -i" works now except for SH_STANDALONE case.
|
|
|
|
|
"sleep 1 | exit 3" + "echo $?" works, "sleep 1 | exit 3; echo $?"
|
|
|
|
|
shows exitcode 0 (should be 3). "sleep 1 | sleep 2 &" fails horribly.

lash, hush: both do setsid() and as a result don't have ctty!
|
|
|
|
|
Ctrl-C doesn't work for any child (try rm -i), etc...
|
|
|
|
|
lash: bare ">file" doesn't create a file (hush works)
|
