. 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
. it's a good extra interface to have but doesn't
meet standardised functionality
. applications (in pkgsrc) find it and expect
full functionality the minix mmap doesn't offter
. on the whole probably better to hide these functions
(mmap and friends) until they are grown up; the base system
can use the new minix_* names
. MAP_SHARED was used to implement sysv shared memory
. used to signal shareable memory region to VM
. assumptions about this situation break when processes
use MAP_SHARED for its normal, standardised meaning
POSIX truncate specification says "Upon successful completion, if
the *file size is changed*, this function shall mark for update the
st_ctime and st_mtime fields of the file." This patch prevents
changing of the date fields when the size stays the same.
. Feature to do a 'release' into a permanent
and usable FS hierarchy, usable with chroot
. Just like the temporary staging hierarchy really
. Useful to checking out and building the latest
version of minix from a host minix; to
(1) make an uptodate minix jail, and
(2) make a sterile, reproducible jail environment, and
(3) use as disposable environment in which moving /usr/pkg
is ok
(i.e. pkgsrc bulk builds)
. strerror() assumes this
. remove generated libminc/errlist.c
. errno's in <sys/errno.h> have to be in sorted order
. filtering out some errno.h in Makefile lets us use near-stock
errlist.awk
* VFS and installed MFSes must be in sync before and after this change *
Use struct stat from NetBSD. It requires adding new STAT, FSTAT and LSTAT
syscalls. Libc modification is both backward and forward compatible.
Also new struct stat uses modern field sizes to avoid ABI
incompatibility, when we update uid_t, gid_t and company.
Exceptions are ino_t and off_t in old libc (though paddings added).
