The bsd signal names are out-of-order compared to the minix ones.
I found out (the hard way) that the (MINIX-descending) ordered list of
signals in <sys/signal.h> does not match the (BSD-descending) ordered
list of signals in usr/src/lib/libc/nbsd_libc/gen/sig{name,list}.c
Beyond being unfortunate, it prevents the trap command of ash to handle
correctly a named signal; a funny test case is
#!/bin/sh
trap 'echo trapping signal BUS' BUS
trap 'echo trapping signal 10 (USR1)' 10
trap # show me what is currently trapped
As a quick workaround, I disabled the use of the libc-provided
sys_sig{name,list} arrays for ash, and reverted to the hand-made array
which is used by the less capable MINIX libc. It allowed me to use
pkgsrc.
. needed for netbsd libc dns resolution
. points to minix nonamed
. /etc/resolv.conf should have the real info
(written by netconf / dhcp client)
. nonamed should be phased out but will probably
be around for the 'old' libc
. fold 2 exception-in-kernel cases (pagefault and rest)
into 1
. for exceptions that occur in kernel, don't just print
kernel stacktrace (typically that is just the exception
handler) but also the stacktrace of when the exception
happened
. don't install minix <termcap.h> as libterminfo
has its own (but still install it in /usr/include.ack)
. forget minix termcap functions in -lcompat_minix
. make commands use -lterminfo in netbsd libc compile mode
. speeds up mkdep (i.e. world builds) significantly
. have to keep minix /bin/sed for a while because previous
usr/etc/rc depends on it
. force mkdep to use /usr/bin/sed for speedup
Improves cache locality by grouping together dependency generation
with building for each program instead of doing a whole-tree dep
generation phase followed by a whole-tree build phase
