Hi Andrei,
Thanks very much for your reply.
Could you try the unstable (cvs HEAD) version? There are some SYSV lock
fixes in it which were not backported to stable.
I will try it soon and report results. .
(note: all builds are done with OPENBSD_IS_AOUT=no
all tests are run as a non-priv user although running as root
produces identical behaviors but also occassionally huge core
dumps)
First I should mention the /dev/random on OpenBSD 3.2/sparc is reserved
for non-existant hardware random number generators; I realize that
you fall back to other methods but would it make sense to use one of
the other available /dev/*random* devices in OpenBSD?
Next, an experiment was to build it with 'posix sems' support;
when run as 'ser -m 8 -E -ddddddddd' I get:
0(32138) WARNING: could not read from /dev/random (5)
0(32138) read 0 from /dev/random

Too much shared memory demanded: 8388608
0(32138) shm_mem_destroy
0(32138) destroying the shared memory lock
note: '-m 1' in the command line produces the same behavior
/var/log/messages:

Next, I discovered that OpenBSD 3.2 pthreads exists and fixed problems
from the 2.x releases. I was able to build 'ser' with pthreads using
the '-pthread' switch in the gcc command-line at link time.
Now, here are the results from running the 'pthreads' version:
$ ser -E -m 8 -ddddddddd

Here are the major problems:
1. '-D' doesn't prevent forking to background
2. no fifo is created regardless of the 'fifo=' statement in 'ser.cfg'
or the command-line '-i' argument
3. no additional debug information is logged to syslog or stderr than
what is printed above (the only syslog message is "can't read from
/dev/random")
Permissions are correct for creating a fifo in the specified directory
(I ususally use /tmp).
'ser -c' reports 'ser.cfg' is ok.
The build of the 'ser' executable had no warnings; the only changes I
made were to Makefile.defs for the build environment and to 'locking.h':
66,69d65
< /* Addn'l defines -- MSG */
< #ifndef L_CRIT
< #define L_CRIT 2
< #endif
74d69
< #include <sys/errno.h>
These were necessary to complete the build.
I would appreciate any advice before I start peppering the code with
printfs.
