prototypes for all syscalls. The args structs are still declared in
comments as in VOP implementation functions. I don't like the
duplication for this, but several more layers of changes are required
to get it right. First we need to catch up with 4.4lite2, which uses
macros to handle struct padding. Then we need to catch up with NetBSD,
which passes the args correctly (as void *). Then we need to handle
varargs functions and struct padding better. I think all the details
can be hidden in machine-generated functions so that the args structs
and verbose macros to reference them don't have to appear in the core
sources.
Add prototypes.
Add bogus casts to hide the evil type puns exposed by the previous
steps. &uap[1] was used to get at the args after the first. This
worked because only the first arg in *uap was declared. This broke
when the machine- genenerated args struct declared all the args
(actually it declares extra args in some cases and depends on the
user stack having some accessible junk after the last arg, not to
mention the user args being on the stack. It isn't possible to
declare a correct args struct for a varargs syscall). The msgsys(),
semsys() and shmsys() syscall interfaces are BAD because they
multiplex several syscalls that have different types of args.
There was no reason to duplicate this sysv braindamage but now
we're stuck with it. NetBSD has reimplemented the syscalls properly
as separate syscalls #220-231.
Declare static functions as static in both their prototype and their
implementation (the latter is optional, and this misfeature was used).
Remove gratuitous #includes.
Continue cleaning up new init stuff.
failed when there was an obj directory. Use .PATH.n for installing too
so that make can find the source files. This allows the source files to
be in several directories (the old method using cd only works well for
a single directory). The dependencies are on the source files even for
the compressed case, although it would be more flexible to depend on the
files being installed, so that `make install' doesn't attempt to build
things
Force COPY to -c for the NOMANCOMPRESS case. Then the files to be installed
are always sources, so they must not be moved.
bsd.man.mk when I change the latter to use `::' instead of `:'
dependencies. (bsd.man.mk is included because NOMAN isn't defined.
The maninstall target is supposed to be private to bsd.man.mk so
bsd.man.mk doesn't bother testing if it is already defined. The
test for redefinition in Makefile.dev was too early to do anything.)
Change install target to a beforeinstall target (perhaps there should
be an `extrainstall' target so that Makefiles don't have to abuse
one of beforeinstall, install, realinstall or afterinstall). Don't
bother testing for the install target already being defined. Rewrite
the shell loop as a make loop (this reduces the time for installing
groff from 78s to 65s here).
include this in the old makefiles.
I intended to fix only the private maninstall rule but found a lot of
other bogons and bugs:
- strong resistance to installing the program anywhere other than
${DESTDIR}/usr/bin (first, ../../Makefile.inc was not included.
../Makefile/inc was redundantly included instead. Second, /usr/bin
was hard coded).
- the owner, group and permissions were hard coded.
- the man page was installed twice.
- MANDEPEND wasn't necessary.
- calculations to determine the obj directory weren't necessary.
- there were unnecessary private rules for depend, rcsfreeze and tags.
We don't support the rcsfreeze target.
- there was an extra, bogus, rule for `all'.
The final version uses suffix rules to eliminate the remaining verboseness
involving directories (${.CURDIR}) and to potentially allow multiple
shell programs in one directory.
that the FTP install doesn't deal with timeouts and hasn't since it was
written. Fixed.
2. Totally eliminate the OptionFlags. I only had to work harder to
sync them with configuration variables, so why not simply always use
configuration variables? This has actually greatly simplified areas
of the code.
The private clean rules have been broken since we started
building compressed man pages in the obj directory and the
others don't do anything different from the general rules.
strings describing the drive status and error bits are so deficient
that the pointer is always NULL.

handler (remove SA_NODEFER).
On the other hand, signal() case should set sa_flags to SA_NODEFER as
in previous change.
In addition, added #ifdef'd code for signal() to or in SA_RESETHAND
flag for when that compatability is implemented.
o fix brokeness for 1>&5 redirection, where `5' was an invalid file
descriptor, but no error message has been generated
o fix brokeness for redirect to/from myself case
valid bytes, we must also clear the B_DONE flag. Some filesystems
depend on this (incl NFS) and is probably the cause of the biodone
error and subsequent crash. Anyway this change needs to be made.
Add SA_NODEFER define to signal.h
Add ps_nodefer field to struct sigacts in signalvar.h.
Add code to kern_sig.c to handle SA_NODEFER.
If flag is set, when the signal is delivered, it is not masked automatically
from receiving the same signal again.
