syslog connections unless they were rejected. This helps save wear and
tear on the syslog facility in large networks with many clienst systems.
yp_svc.c: Be a little smarter about using sigaction() -- set the SA_RESTART
flag.
svc_run: Be doubly paranoid about killing off child processes. Do a flag
chack and a pid check before letting child 'threads' self-destruct.
- There are two cases where the server can potentially block for a long
time while servicing a request: when handling a yp_all() request, which
could take a while to complete if the map being transfered is large
(e.g. 'ypcat passwd' where passwd.byname has 10,000 entries in it),
and while doing DNS lookups when in SunOS compat mode (with the -dns
flag), since some DNS lookups can take a long time to complete. While
ypserv is blocked, other clients making requests to the server will
also block. To fix this, we fork() ypall and DNS lookups into subprocesses
and let the parent ypserv process go on servicing other incoming
requests.
We place a cap on the number of simultaneous processes that ypserv can
fork (set at 20 for now) and go back to 'linear mode' if it hits the
limit (which just means it won't fork() anymore until the number of
simultaneous processes drops under 20 again). The cap does not apply
to fork()s done as a result of ypxfr calls, since we want to do our
best to insure that map transfers from master servers succeed.
To make this work, we need our own special copy of svc_run() so that
we can properly terminate child processes once the RPC dispatch
functions have run.
(I have no idea what SunOS does in this situation. The only other
possibility I can think of is async socket I/O, but that seems
like a headache and a half to implement.)
- Do the politically correct thing and use sigaction() instead of
signal() to install the SIGCHLD handler and to ignore SIGPIPEs.
- Doing a yp_all() is sometimes slow due to the way read_database() is
implemented. This is turn is due to a certain deficiency in the DB
hash method: the R_CURSOR flag doesn't work, which means that when
handed a key and asked to return the key/data pair for the _next_
key in the map, we have to reset the DB pointer to the start of the
database, step through until we find the requested key, step one
space ahead to the _next_ key, and then use that. (The original ypserv
code used GDBM has a function called gdbm_nextkey() that does
this for you.) This can get really slow for large maps. However,
when doing a ypall, it seems that all database access are sequential,
so we can forgo the first step (the 'search the database until we find
the key') since the database should remain open and the cursor
should be positioned at the right place until the yp_all() call
finishes. We can't make this assumption for arbitrary yp_first()s
and yp_next()s however (since we may have requests from several clients
for different maps all arriving at different times) so those we have
to handle the old way.
(This would be much easier if R_CURSOR really worked. Maybe I should
be using something other than the hash method.)

platform, I discovered the following: if you use ypcat (or anything that
does a yp_all() for that matter) to dump out a map and then hit ^C before
it finishes, ypserv gets hit with a SIGPIPE and dies. (The ypall() service
is implemented using TCP.)
Fix: ignore SIGPIPEs.

on dlclose. Also correctly call constructors and destructors for libraries
linked with /usr/lib/c++rt0.o.
Change interpretation of dlopen manpage to call _init() rather than init()
for dlopened objects.
Change c++rt0.o to avoid using atexit to call destructors, allowing dlclose to
call destructors when an object is unloaded.
Change interface between crt0 and ld.so to allow crt0 to call a function on
exit to call destructors for shared libraries explicitly.
These changes are backwards compatible. Old binaries will work with the new
ld.so and new binaries will work with the old ld.so. A version number has
been introduced in the crt0-ld.so interface to allow for future changes.

cpio/copyout.c:
Don't output a file if the major, minor or totality of its rdev would be
truncated. Print a message about the skipped files to stderr but don't
report the error in the exit status. cpio's abysmal error handling doesn't
allow continuing after an error, and the rdev checks had to be misplaced
to avoid the problem of returning an error code from routines that return
void.
pax/pax.h:
Use the system macros for major(), minor() and makedev().
pax already checks _all_ output conversions for overflow. This has the
undesirable effect that failure to convert relatively useless fields
such as st_dev for regular files causes files not to be output. pax
doesn't report exactly which fields couldn't be converted.
tar/create.c:
Don't output a file if the major or minor its rdev would be truncated.
Print a message about the skipped files to stderr and report the error

tar/tar.c:
For not immediately fatal errors, exit with status 1, not the error count
(mod 256).

Minor numbers are limited to 21 bits in pax's ustar format and to 18

pax's and cpio's ustar format is incompatible with gnu tar's ustar
format for other reasons (see cpio/README).

In the case where ypserv is started with the -dns flag, fall through to

incorrectly handed off to DNS.

The shlib code is not capable of supporting this feature in it's present

register ourselves as an NIS version 1 UDP server to pacify older SunOS 4
ypbinds that seem to insist on having one around. All this does is allow
ypserv to respond to DOMAIN_NONACK requests that are periodically
transmitted by ypbind: the server will not actually work as an NIS v1
server in any other way.
Unlike the mainline code, which implements this as a compile-time
option, this feature can be turned on with the newly-added -k flag
at runtime.

ypxfr can't easily be reduced down to one file like yppush because it
needs to do certain special things (such as binding to a specific
machine (the NIS master)) which the yp_*() functions in libc don't
allow.
in libc, we can get rid of the private/special copies of yp_*.c
files and rpcgen them at compile time instead. This leaves us with
just one unique source files: yppush.c

that ypxfr is supposed to log messages to /var/yp/ypxfr.log if it exists,
using syslog() makes more sense, especially since ypserv does the same
thing already. Try to use stderr by default, and use syslog() if stderr
is not a tty.
Also update the man page to reflect this change.

Have ypxfr log all output to /var/yp/ypxfr.log if stdin is not a

It now explicitly requires the specification of a directory to import
from, either as an argument to the script, or by asking the user about
it. (Previously, it implicitly used `.', like cvs import does.)
Also implemented an option `-n', which does essentially the same like
the overall CVS option `-n': show only what would have been done,
don't do any commitment. Note that since the modules' database is
checked out in place (and not commited back), it will erroneously be
reported as to be imported, too:
cvs import: Importing /home/ncvs/ports/foobar/foo/modules
I ports/foobar/foo/modules/CVS
N ports/foobar/foo/modules/modules
This is an unwanted side-effect, but gives the user the option to see
if the `ed' magic did the right thing when editing modules/modules.
Rod, can you please check the function ``checktag'' in the script if it
will be restritctive enough?
